  (September 2003) 

Q: Has anyone tried failsafe for Lupus?

A: Yes, the Illawarra failsafe group reports great success with both Lupus and arthritis. More details from Bernard: btrudget@ozemail.com.au.

Q: I read about Lactobacillus GG, probiotics and Vaalia yoghurt in your book 'Fed Up with Asthma'. Are you aware that Vaalia yogurt contains natural colour 160b?

A: You should be able to get Vaalia natural yoghurt which is colour-free. It is only the vanilla and fruit-flavoured Vaalia yoghurts which contain 160b. Please let me know if your Woolworths supermarket refuses to stock Vaalia natural (give the location of the supermarket).

Q: Sometimes I have this uneasy feeling when I breathe, it is as if I am on a plane flying at 40 000 feet and having that dry feeling in your throat and eyes. I keep thinking that it must be something that I eat or drink. I have had it after a fruitcake and also from raisin bread. My daughter avoids cask wine for the same reason.

A: For breathing problems within 15 minutes of food or drink, suspect sulphites (220-228). Raisins and dried fruit such as cherries and artificial cherries in fruit cakes etc may contain sulphites. Wine is the other most common source of sulphites. Asthmatics who see an occasional reaction to sulphited foods are probably affected more than they realise.

Q: I came across the new Cottees Lemonade the supermarket today, and was wondering if it is failsafe? The ingredients are carbonated water, sugar, food acid 330, natural flavour.

A: These ingredients are the same as in 7UP and Schweppes lemonade. The natural flavour is lemon juice, which contains both salicylates and amines. For the elimination diet, the RPA recommended limit is 150 mls per week (less than one glass). In my experience, most parents give more than that and then complain that their children react. Best to save it for treats such as birthday parties.

Q: We live on a farm in WA and I am planning for the whole family to do the Elimination Diet. I am determined to persevere this time, nearly 5 years after our first attempt. I think the best way for me to ensure we stick at it is to do a thorough menu plan, including lunch boxes and snacks; to do a big shop in Perth for food and non food items; discuss incentives and rewards before commencing; clear my diary of all unnecessary time-consuming, stress-inducing appointments, meetings etc; advise the school and other relevant people; keep a food and behaviour diary; communicate frequently with the dietitian. Have I missed anything? Is Amway still OK for washing clothes and Imperial Leather for personal soap? (I see toothpaste is available by mail order). We buy our meat in bulk (about every 3 months). Our butcher cooks a chook for me on the rotisserie without anything added. I use the white meat only (no skin) for the children's lunches. Is this OK?

A: It all sounds good except the meat. Meat should be cooked the day you buy it or frozen and used within 4 weeks. If you pass your amine challenge you can go back to buying in bulk every three months.

Q: A few months ago, I developed a cough and tight chest which got worse and now I have been diagnosed with asthma for the first time in my life (I am 35). I am on a weight loss diet and have been snacking every day on a mixture of dried fruit and nuts. I saw your factsheet about asthma and muesli bars. Could dried fruit cause chronic asthma?

A: Dried fruit such as apples, apricots and coconut contain sulphur dioxide (220 also called sulphites). Sulphites are strongly associated with asthma. It is possible for some people to develop chronic steroid-dependent asthma simply by eating dried fruit in muesli bars or trail mix nearly every day. If cutting out the trail mix doesn't help, you may need to investigate the effects of other food chemicals including salicylates (more details in Fed Up with Asthma).

Q: Is there a failsafe lipbalm?

A: I haven't found one yet. I use vaseline. Any suggestions from readers?

Q: My problem has been a severe burning sensation on my face, especially temples and nose, on and off for the past year. I have recently started the failsafe diet and on the salicylate challenge my skin became so painful and my face was swollen, that I had to use liberal amounts of cortisone cream. I work in a shoe shop and have always had a bad reaction while at work. As soon as I leave work I have no discomfort. This happened on the challenge, but the reaction was only on that day that I worked. I have not had such a bad reaction since, but even this week, there was a slight tingling on my skin, but only while I was at work. Could my reaction be coming from something at work?

A: Exposure to toxic chemicals (such as the glues and solvents used in shoe manufacture) can sensitize you to other chemicals including food chemicals. You can identify occupational exposure because of the timing: your symptoms will occur at work, (or for asthma, more often on work nights) and stop during holidays. If you continue to be exposed at work, eventually your symptoms will become irreversible. The best cure is to change your job. Easy to say, hard to do, but you run the risk of becoming far more sensitive if you don't. See the Fumes and Perfumes factsheet on the website and the section on occupational exposure in Fed Up with Asthma.

Q: I have been reading some information about a new milk product called A2 milk that will soon be available in Victoria. Do you know anything about it?

A: If you can tolerate cows or goats milk, A2 (it's a form of milk protein called beta-casein) will be suitable for you. Most milk in the world is A2 milk - Asian and African cows milk, goats milk, yak milk etc. Most milk in Western countries is not A2, except for occasional breeds such as Guernsey cows. There is some interesting research suggesting that A2 milk is better for health in a number of areas, including autism and heart disease. It would be relatively easy to convert Western milk to A2 if dairy farmers wanted to do it. You can read all about it by doing a google search: www.google.com SEARCH "A2 milk"

Q: Are there any failsafe worm tablets?

A: None of the standard pharmaceutical treatments are failsafe but one reader's pharmacist recommended large doses of garlic - three cloves a day, with the garlic in the biggest chunks the child can swallow, to allow pieces of garlic to actually get right through the intestines (Nuttelex on the lumps makes it easier to get down) plus four odourless garlic tablets a day, plus a multivitamin supplement (we recommend Macro M or Amcal). He also recommended no sugar for a week although you can have permitted fruit.

Q: I am 5.5 months pregnant and have had chronic insomnia since being pregnant. I have gone to a sleep clinic and am beginning to think that my insomnia is closing related to MSG. I have been keeping a sleep diary and it appears that on the nights after I go out for lunch or dinner I may not sleep at all or only get a few hours sleep. Just recently I bought Woolies BBQ chicken not realising this would contain MSG, both nights after these chickens I did not sleep at all. Ever since becoming pregnant I have been going out to lunches an awful lot, so I can look back and say 'yes 3 times a week, no sleep, yes could MSG be the problem here?' Do you know of anyone else that has insomnia from MSG? I find I am thirsty, have nightmares, have developed a rash on my calves and do not fall asleep. It is very hard to find out which restaurant foods may contain MSG. Do you have a list?

A: Other people are affected by MSG too, see Reader's story 'Bad insomnia caused by MSG and preservatives'. For detailed information about how to avoid MSG, see pages 193-196 in Fed Up with Asthma. Since you developed a rash after eating Woolies chicken, I would also suspect ribonucleotides (flavour enhancers 635, 627 and 631). If avoiding MSG and ribonucleotides doesn't stop your insomnia, you may want to try the failsafe diet to see if other food chemicals are contributing to your problem.

Q: Are Neways products failsafe?

A: You will have to judge each product individually. The Radiance toothpaste without peppermint oil (there are two Radiance toothpastes) is OK without the mouthwash. The only other products I have tried (shampoos and conditioner) are not failsafe because they contained very high salicylates in ingredients such as tangelo oil, despite the 'fragrance free' label. I normally use Palmolive Naturals shampoo and conditioner for normal hair, available from supermarkets. They are not 100% failsafe but I can tolerate them, unlike the Neways products. Dermaveen shampoo and conditioner from pharmacies are 100% failsafe.

Q: My baby is 4 1/2 months old. He's never been a great sleeper and since I started him on solids three weeks ago at least one breastfeed a day is a nightmare - he will drink for a minute or two then pull off and scream and arch his back. People told us he would be more settled on solids! I've given him potato, sweet potato, pumpkin, apple and avocado and I can't say I've noticed any of these really affecting him. Can you suggest what foods I should be giving him?

A: Some babies are more sensitive than others. You won't always see an immediate reaction but effects build up. Apple and especially avocado are not great for babies with food intolerance because they are high in natural chemicals called salicylates. Homemade baby rice cereal (cooked and blended rice) is generally very safe and you could try potatoes and baby pear. Bananas are good unless your baby reacts to natural food chemicals called amines. If you are breastfeeding you may have to change your own diet too. There are more details in The Failsafe Cookbook, or you could see a dietitian.

(June 2003)

Q. I had two sips from a bottle of the new Pepsi Blue and within 30-40 seconds I became violently ill. I was taken to hospital and it took me approximately ten days to recover fully.

A. Pepsi Blue contains two artificial colours, Allura red 129 and Brilliant Blue (133, Blue #1). Except for ribonucleotides (flavour enhancer 635), it is very unusual to experience a ten day reaction to food additives, but we have once before received a report of a dramatic ten-day reaction to Brilliant Blue.

Q. We have been doing to the diet now for 2.5 weeks and we are really struggling. My daughter's behaviour seems to a be a little worse than before, crying, pains in tummy, tantrums, irritable, and my son is very grumpy. I have read stories/frequently asked questions and I may be feeding them too many LCM's ( only 1 per day). I have just discovered that Helgas ( which we have been living on) is not failsafe! … I'm now off to Brumbys.

A. The diet will not work if you make mistakes. Read the Checklist of Common Mistakes on the website. I don't recommend any LCMs until your children have already turned into angels, and even then, be careful. Many children can't manage them. If they set up a craving, avoid them. It is also essential to get your bread right.

Q. We have definitely seen an improvement overall in my son at school since going failsafe, but not a total elimination of all behavior issues, just more tolerable - so it may mean we haven't gotten it all yet. How much vanilla is too much? My children have vanilla in cookies, vanilla flavoured soy milk and icecream.

A. Vanilla is supposed to be limited to 2 drops per day, but if the diet isn't working 100 per cent for you, try cutting it all out for a few weeks, and especially the vanilla flavoured soydrink.

Q. Mannateck Phytobears changed my daughter into a squealy, unsociable little two year old. What's in them?

A. Phytobears are very high in salicylates and/or amines (in broccoli, cauliflower, kale, tomato, turnip, onion, carrot, papaya, pineapple, ambrotose, aloe barbadensis, larix decidua, astragalus gummifer, anogeissue latifolia) and also contain annatto 160b natural colour, the only natural colour which affects some kids as badly as artificial colours although it is often a next day grumpy reaction. A few people have reported that their children improve on phytobears - they must be kids who don’t react to salicylates, amines or annatto.

Q. Are you able to help me with ideas on how to change school lunch order choices? My daughter's school has a terrible list (party pies and choc donuts).

A. See the website for the School Tuckshop Factsheet. People say it is very helpful.

(April 2003) 

Q. My son is 4 years old and he has been diagnosed with borderline ADHD and the children's doctor has recommended I take him off all preservatives and colours. I am wondering if there is a list of what preservatives are the best to avoid?

A. It is good to hear that doctors are now recommending avoidance of food additives. However, children with ADHD are equally likely to be affected by natural food chemicals called salicylates. It would have been more helpful for your doctor to refer you to a failsafe-friendly dietitian for a 3-week trial of the elimination diet (a list of failsafe-friendly dietitians is available, ask us).

Q. My butcher is going to try and make bacon or corned beef without nitrates. Its all too complicated for me but am happy to let him try BUT he needs to know if he can use saltpetre. Have you ever heard of this? He said this is what butchers would have used before nitrates. He wonders if it is nitrates under an old fashioned name.

A. Saltpetre is an alternative name for potassium nitrate and Chile saltpetre is an alternative name for sodium nitrate. Both are naturally occurring minerals used in the manufacture of gunpowder, in metallurgy, as a fertiliser, preservative, colour-fixer and curing salt. Potassium nitrate can also be artificially manufactured. Saltpetre is not failsafe. If you have passed your amine challenge, you can do a nitrate challenge (large serves of bacon or corned beef every day for three days while otherwise failsafe) to see whether you react.

(February 2003)

Q. The front page of your website lists frequent nose bleeds as an FI symptom. Under what conditions do these nose bleeds occur and what foods seem to be implicated? My wife gets unexplained nosebleeds fairly often. Her doctor can find nothing as a cause.

A. In my experience, dairy foods are a big contributor, but everyone is different so you would have to consider the usual suspects (additives, salicylates etc).

Q. How can I eat well and stay sane at the same time? I would like to lose a bit of the weight that I have put on in the last 12 months and altogether I need to lose about 8 kgs.

A. See the new factsheet on the website, Failsafe Weight Loss, I've tried it and it works.

Q. Our pediatrician recommended Fergon elixir iron supplement. I was wondering if my daughter can take this while on the elimination diet? This supplement contains Glucose liquid, Ethanol and Saccharin Sodium.

A. You can't trust labels on pharmaceutical products, because they don't have to declare all additives. Here are the actual contents of Fergon, as listed on the CMI (Consumer Medication Information sheet), available in the packet or at www.myDr.com.au :

Active Ingredient: Ferrous Gluconate 300mg in 5mL

Other Ingredients: Glucose Liquid, Glycerol, Ethanol (alcohol), Saccharin Sodium, Gluconolactone, Apricot Superarome, Water - Purified

The strong apricot flavour ('super-aroma') is not failsafe. All strong fruit flavours are very high in salicylates.

For more details, see the new Supplements factsheet on the website.

Q. In the last 2 or 3 months, my stomach has been almost continuously bloated. On occasions the amount of gas in my stomach is so extreme that I have to force myself to burp to relieve the pressure in my stomach. I doubt that my diet is a problem as my wife and I eat low fat and very healthy. I am an otherwise healthy 31 year old non smoker and very mild drinker. However, I have recently begun chewing 'x.cite' chewing gum several times a day, ingredients: maltitol, gum base, flavour, thickener 414, emulsifier (322, from soy), colour 171, sweeteners (951, 950), glazing agent 903, antioxidant 320. Do you think that the gum may be the reason for my problem?

A. Maltitol can cause the problems you mention. Sugar alcohols including maltitol, sorbitol (420), mannitol (421), xylitol (967), glycerin (422) and hydrogenated glucose syrup (965) are used in 'sugar-free' chewing gum and candies and in low joule or carbohydrate modified food including icecreams and jams. Although sugar alcohols are chemically related to sugars, they are not as sweet, don't cause tooth decay and are poorly absorbed into the blood stream. This poor absorption means they can work their way through the digestive tract, causing bloating, abdominal pain and severe diarrhoea. The FDA requires a warning about 'laxative effects' on foods containing more than 50 grams. The trouble is, consumers are affected by a lot less than that. In 1999, the Centre for Science in the Public Interest (www.cspinet.org) petitioned the FDA to require foods containing more than one gram or more to bear a label stating: 'This product contains sorbitol (or whatever) which may cause diarrhoea, bloating and abdominal pain…'. No response from the FDA so far.

Q. Thanks for your website. I was excited to see your section on "Additives around the world" listed but sorry not to see a section about France.

A. I didn't write much about France because the food is so good there! French people seem very aware that fresh food is best, most seem to be against American-style food, and very few additives are used as far as I could see. French bread is excellent. Of course, if you buy American-style foods then you will have problems with the same additives as everyone else. You do need to be aware of additives in medication. There are many articles in French medical journals about this - and again, French doctors seem to be more aware of the problems than most - see article about asthma and benzoates in the last newsletter.

Q. I notice that you don't include Helga's in your list of preservative free breads, however according to the label it contains only emulsifiers - is there something else in there?

A. Helga's bread usually contains either vinegar (which is not failsafe) or extras such as linseed and corn which are not failsafe. If you only have to avoid propionates it is OK.

Q. My 5 yr old son has Williams Syndrome. What I have read on your web page sounds like my son since birth. He has a learning disability but we have also experienced behavioral, sleeping and feeding problems and he never relaxes even while watching TV. Does the diet work for this syndrome?

A. It is possible to have food intolerance by itself or in association with a number of conditions. If your child's behaviour is related to food intolerance, then the failsafe diet will help. There are failsafe families using the diet successfully for children with Fragile X Syndrome, Prader-Willi syndrome, Porphyria and Down Syndrome as well as ADHD, PDD (pervasive developmental disorder), learning disabilities, autism, ODD (oppositional defiant disorder) and CD (both conduct disorder and coeliac disease). The diet will take care of the food-related symptoms but you may need other inventions such as behaviour management, special education, speech or motor-sensory programs. Parents usually find that other interventions are much more effective once the diet has kicked in. See Factsheet - FI and Behaviour.

Q. Can you please give us more info on the asthma meds. Our son is on maximum dosage, what are the alternatives???????????

A. You might like to look at what he eats - see my new book "Fed Up with Asthma".

Q. My daughter is allergic to sulphites, and we have had some very scary and life threatening moments. She is being treated at the allergy clinic but I can't seem to find any detailed information on sulphites.

A. See sulphite list in the asthma feature on the website, and the "how to avoid sulphites" section in my book Fed Up with Asthma.

(September 2002)

Q. My failsafe son has a very bad cold at the moment and I can't seem to find any thing to help ease his symptoms - do you have any recommendations?

A. See the Failsafe Cookbook page 174 for home remedies. Basically, drink lots of fluids - warm magic cordial is excellent - and squirt warm salty water up the nose to unblock. Avoid coloured or preserved syrups and medications. You might like to try white Panadol tablets for pain, Bisolvon white tablets - not elixir - to dissolve mucous and another failsafe possibility is Claratyne white antihistamine tablets, which will dry everything up.

Q. My question is about annatto colour (160b). We get vegetarian sausages (have been vegetarian since birth) from Sanitarium which have annatto and carrageenan (both listed as "natural" additives) in them. When I phoned Sanitarium they said they weren't aware of any negative reactions with either and were, therefore, not prepared to substitute them for something considered safer. I was wondering what annatto is and what reactions to annatto have been reported.

A. Annatto is a yellow colour made from the seed coat of a tropical tree. It is one of 50 additives identified by researchers at Royal Prince Alfred Hospital as most likely to cause adverse reactions. American researchers found more people with urticaria reacted to annatto than to any artificial colours. This network receives frequent complaints about effects of annatto including headaches, headbanging in young children, behaviour problems and even arthritis. Beta carotene (160a) is a safe alternative and is used widely in Europe but our national food authority tells food manufacturers that it is too difficult and expensive to use 160a. See factsheet on website.

Q. I have a autistic and hyperactive son with a lot of challenging behavior. I have read about your research on the internet. When I went to the bakery to buy bread, I was told that it has no 282 but it does have another preservative, is it alright to give my son?

A. Bread preservative 282 is not the only food chemical which can cause behaviour problems but for many families it is one of the worst. You can try bread without 282. If your son still has problems, I suggest you read my books Fed Up or the Failsafe Cookbook.


Q. I recently purchased some rice pasta from Freedom Foods. It has Inulin (dietary fibre ) in the ingredients. Do you know what this is derived from? Is it safe?

A. Inulin is a starch derived from the root of a lily. It is highly refined, like cornflour, and thus failsafe, we would have thought. However, there has been one possible adverse reaction reported from a very sensitive member of the network.

Q. Can you recommend a non-toxic way of sealing a timber floor?

A. Bio Paints do natural organic varnishes as well as paints, freecall 1800 809 448 for information and free coloured brochure. Try also Berger "Breathe Easy" brand.

Q. My doctor says that if my son's behaviour can be controlled by diet, it's not ADHD.

A. Your doctor's information is out of date. He needs to read "Diet, ADHD and behaviour: a quarter-century review" by the highly regarded and unbiased (that is, not industry-funded) Centre for Science in the Public Interest. You can download the 40-page report from their website (www.cspinet.org) or see my website for a summary.

Q. Can you tell me if tonic water and soda water are OK? (ie: gin and tonic, scotch and soda) and if these alcohol mixes should be limited (from a chemical rather than an alcohol point of view)?

A. Soda water should be OK, tonic water varies. Schweppes is preservative-free, Kirklands is not and don't drink tonic water on tap. Purely from a food chemical point of view, gin and preservative-free tonic and scotch and soda are unlimited …

Q. I was so impressed by the change in my son's behaviour just by going failsafe that I would like to lobby the school where he attends to change the foods sold from the canteen. I am really dedicated to making these changes as I believe that even by changing the breads used you can make a huge difference to kids' behaviour. What is your opinion of how to approach the committee?

A. You might like to print out the tuckshop factsheet on the website. It includes: CSPI recommendations that schools should minimise their use of behaviourally harmful additives; a story about a school that achieved great success by banning additives; and a suggested low additive tuckshop list with some failsafe options. A ban on colours, MSG and the bread preservative is achievable and worthwhile.

Q. Are there any failsafe moisturisers?

A. Look for products without perfume. Sorbolene is the product best tolerated by very sensitive people. See also the Q.V. range by Ego Pharmaceuticals, and the Dermaveen range by Dermatech.

Q. Isn't canola oil dangerous?

A. This might be an urban legend running wild on the internet. See http://www.urbanlegends.com/ulz/canola.html

Q. What is your personal opinion of medication for ADHD?

A. I agree with the CSPI report (see www.cspinet.org): parents should be warned of the adverse effects of medication, offered the option of diet, and use medication as a last resort rather than the first and often only option.

Q. I've been doing the failsafe diet with my son for two weeks. Already he seems to be less angry and has more self control. Two days ago he had king prawns for tea and today he seems more uptight again. What is it in prawns that that causes this reaction?

A. Prawns - and most seafood - are high in amines. The only exceptions are very fresh white fleshed fish (not tuna or salmon) and white fleshed seafood, eg fresh crab, lobster, calamari, scallops and oysters. Caviar is very high in amines.

Q. Is sake failsafe?

A. Sake is low in salicylates but contains amines.

Q. What's the colour that makes some egg yolks much darker than others? My son seems to react to them.

A. I am waiting for a reply from the Australian egg industry. In Britain, chicken feed often contains canthaxanthin (E161g), citranaxanthin (E161i) and beta apo81 carotenal (E160). See for yourself what it does to the eggs - http://www.iceland.co.uk/Ext_11/web/Market.nsf/(WebSearch)/CusEggs/ . Also see two interesting articles about colours fed to chickens, fish (farmed salmon) and animals to enhance the colour their eggs or flesh, see http://news.bbc.co.uk and search for canthaxanthin.

Q. My son refuses to have any vegetables.

A. Have you tried vegetable soup? I started with just potato, cabbage and salt blended well so you couldn't tell what was in it, no lumps. My kids only had to lick the tiniest amount off one teaspoon (just touch it with their tongue) the first night to get a reward - a small toy. The next night they had to have more (lick a small amount off the teaspoon) to get another small toy. The next night it was twice as much and so on. By the end of two weeks they would eat a mug of vegetable soup. Then we cut out the rewards and established the most important rule of the house - no dinner until soup is eaten. Since then they have eaten vegetable soup nearly every night of their lives. My 19 yo daughter has been living away from home for a year now. She cooks failsafe vegetable soup once a week, freezes it in one serve portions and has a cup every night. My 16 yo eats a huge serving of soup every day. I can put any failsafe vegetable in the soup including Brussels sprouts, lentils and dried beans and he will eat it without complaint.

Q. Which book of yours should I buy?

A. My books are all different and they are all worth reading. Failsafers tell me that The Failsafe Cookbook is the best one to start on because it is so clear and easy to follow.

Q. We live in SE Asia and the only golden syrup we can get is Tate and Lyle's from the UK. Is that failsafe?

A. I haven't seen Tate and Lyle golden syrup for years, but Rebecca used to react to it. It must contain salicylates. It tastes better than CSR, and the rule is "if you like it, you can't have it". Stick with CSR golden syrup or see the FS Cookbook page 161, for mock maple syrup. You can use that instead but omit the vanilla if your child hasn't turned into an angel yet.

Q. We'd like to break the diet occasionally but not too much. Can you recommend some not-too-bad treats?

A. Everyone is different. It depends what affects you the worst. You have to work it out for yourself. We always avoid additives. Dairy foods are the least of my problems but amines (and salicylates) are bad so a treat for me is a chocolate covered icecream like an eskimo pie. I can manage the occasional slice of rockmelon or watermelon but a whole serve of commercial fruit salad isn't worth the consequences. My daughter can manage some dairy foods, has to be even more careful of salicylates but can manage amines. She sticks to her diet strictly for weeks before important occasions (like exams and performances) then will have a treat like a Sara Lee Chocolate Pudding, Chocolate Bavarian, caramel top n fill on icecream, or Paul's custard (with 169a). She also likes to have a few Dick Smith's shortbread cream biscuits every so often, but she doesn't eat sweets like Werther's original butter candy, Fantales or Pascall's Chocolate Eclairs because they set up a craving. However, my son and I can eat these as occasional treats. Some failsavfers recommend Fads (used to be Fags, imitation cigarettes) and Chuppa Chups cola flavoured - as once a month treats.

Q. Is white chocolate failsafe?

A. White chocolate does not contain any cocoa product, so it won't contain amines to the same extent as brown chocolate. RPA cautiously restrict the amount allowed as they're not sure and the milk itself (because it's 'aged') will probably contain amines. "Flavours" in both white and brown chocolate can be a problem.

Q. Is Sanitarium Organics Simply Soy milk safe or is it too high in salicylates as it contains raw cane sugar?? The ingredients are "Organic whole soy beans, organic raw cane sugar, food acid 332, mineral (calcium phosphate), filtered water added".

A. Not failsafe, sorry. Raw sugar is moderate in salicylates which is definitely not OK if you are drinking it constantly. The fresh Sanitarium So Good with linseed is not failsafe either. The UHT version is failsafe.

Q. On the weekend I gave my 10 yo son a Hungry Jack's strawberry thickshake and fries and within an hour he was extremely rude (threw money at me at the shopping centre because I would not buy him an iced donut). This behaviour happened a few weeks ago after the same food so obviously he won't be getting that again. I wondered if you knew of major problems with these foods?

A. I couldn't find a Hungry Jack's ingredient list on the internet but because he reacted so quickly, your son's reaction is most likely due to artificial colouring in the milkshake. It could be any of the red colours 122, 123, 124, 127 or 129 and possibly some tartrazine as well (102). You might like to reply to the petition above! Also possible is an antioxidant from the range 310-312 or 319-320 in the fries, but these usually cause irritability the next day.

Q. What is it about Weetbix that affects children?

A. I wish I knew. I used to think it was salicylates in the raw sugar, but my daughter reacts even worse to VitaBrits which are sugar free. RPA suggested it could be the wholegrain wheat. A few people report that LiteBix are better.

Q. When our son went to university, he started eating several packets of Burger Rings a day and drinking lots of Diet Coke. He developed a facial tic and failed all subjects. We've never had those kinds of foods at home. Could they have anything to do with his problems?

A. Burger Rings contain the following unsafe additives: colours (102,110,155), antioxidant (319) and MSG (621). Diet Coke contains preservative (211) and artificial sweetener (951). All of the additives above have been associated with adverse reactions by RPA except 951 which has not been tested but is not recommended. Common reactions to food additives include restlessness and inattention which can obviously result in student failure. Tics are less common reactions to food chemicals.

Q. I've just spent more than $200 on a psychiatrist. I told him my son had gone ballistic after eating Chinese takeaway (we ate the meal one day and the leftovers the next day). He told me there was no evidence that food affects children's behaviour, and mentioned a study at the Great Ormond Street Children's Hospital. Have I wasted my money?

A. Your psychiatrist was referring a study which tested only food colouring and found that parents could not distinguish the effects of colours from placebo. Excluding food additives alone is not helpful for the majority of ADHD children, so challenges must be carried out during a comprehensive elimination diet. There are many highly successful studies, including two at Great Ormond Street (Egger and others, 1985, Carter and others 1993) which avoided more foods. I suggest you send your psychiatrist a copy of the press release about diet and children's behaviour from the Centre for Science in the Public Interest www.cspinet.org

Q. I'd like to write a book about my experiences. Can you give me any hints?

A. Writing is time-consuming and poorly paid. The Australian Society of Authors (www.asauthors.org) calculate that authors are paid less per hour than any other occupational group including fruit-pickers. I would have made more from one year of teaching than from 2 best-selling books over 8 years. Publishing houses pocket 90% of the RRP, so the author gets about $2 for a $20 book. You keep a lot more of the profit if you self-publish, but the publishing houses get bigger distribution so spread the word much better. Only about 1% of manuscripts submitted to publishers are accepted. See the Writers and Artists Yearbook in your library for information about publishers.

Q. What's in Coke? I'm addicted to it and I'm sure it's bad for me.

A. Most people blame caffeine, which is a drug and does cause addiction. The definition of addiction is doing something that makes you feel good until it makes you feel bad. Caffeine can cause anxiety, jitters and agitation. Some people are more sensitive than others. Diet Coke contains aspartame artificial sweetener (951) which is very addictive for some people. It also contains sodium benzoate preservative (211), one of the worst preservatives. People who drink a lot - sometimes one can/hour or up to 7 litres a day - are exposed to very high doses. Coca-cola is free of aspartame and preservatives but the flavours include essential oils of lemon, orange, nutmeg and cinnamon, so it is high in salicylates (about the same salicylates as a glass of juice), especially in large quantities. If you want to support the Coca-Cola company, buy Mt Franklin spring water. Use soda bicarb to overcome cravings and withdrawal symptoms.

Q. What exactly are those kids eating on the cover of the Failsafe Cookbook?

A. It was a ham and tomato roll - not failsafe, but it's a great photo. So I asked the graphic artist to make the ham look like chicken and the tomato look like beetroot which is moderate in salicylates. I would prefer the lettuce to be iceberg but you can't have everything.

Q. Where is the evidence that whey powder is a natural form of calcium propionate (282)?

A. Bonita Glatz, professor of food science at Iowa State University, describes the disadvantage of propionic acids used as a preservative: "The pure acid or propionic salt must be labelled as a preservative when added to a food, thus precluding the use of the desirable term "all natural". She then provides an option: "Alternatively, the propionibacteria may be grown in a natural medium such as milk or cheese whey and the entire medium … may be dried and used as a natural preservative". Ref: Glatz, B. "The classical propionibacteria: their past, present and future as industrial organisms" American Society for Microbiology News, 1992, vol 58, no 4, 199-200.

Q. Help. Where do I start?

A. This is definitely the most frequently asked question. Write down everything your child normally eats in a day. Now check whether they are failsafe by going the list of failsafe foods (in the booklet from your dietitian, also page 206 Fed Up, page 195 FS Cookbook) or the recipes. If not, write down a substitute for each food. For example, breakfast: Nutrigrain. Not failsafe. Use Rice Bubbles or rolled oats instead. Raw sugar. Not failsafe. Use white sugar instead. Milk. Decide whether you will include milk or not (eg if frequent ear infections, switch to Vitasoy Calciplus). Toast. Read label on bread and switch to preservative-free bread. Margarine. Read label and switch to Nuttelex. Vegemite. Not failsafe. Switch to golden syrup, pear jam, or Nuttelex with sprinkle of salt. Eggs. Failsafe. Pancakes. Failsafe. Read label on maple syrup and switch to pure. Vitamins. Throw out chewable child tablets and switch to Macro M or Amcal One-a-Day. Morning tea. Fruit. Not failsafe. Switch to peeled ripe soft and juicy pear, or read through snack suggestions in the recipe section and choose something your child will like. Eg. Saltine crackers with nuttelex, or Margie's lunchbox muffins … and so on. If you have the FS Cookbook, read "How to Start" on page 18 and the Checklist of Common Mistakes on page 207 (or on the website). Any questions, join the discussion group, phone your local contact, or email me for support.

Q. Help! Where do I start?

A. Thanks to a reader for this answer: "I think the biggest hurdle is that first shopping trip. I picked out several recipes I wanted to try, and carefully reviewed the list of acceptable foods. I made sure I put all the ingredients I needed for the recipes on my shopping list, along with acceptable foods, including goodies like chips, pretzels and ice cream. At the supermarket it did take a long time to find all the new things I was buying, but when I got home, I had a kitchen full of failsafe products and all the ingredients I needed for some failsafe recipes. Having all those things in the house made following the diet a lot easier. I'm such an organizational freak that I have my shopping list on the computer. I print out copies and post them on the refrigerator; then I check off the things I need as they run out. On the back, I print out the additives to avoid, so I always have it with my shopping list when I'm shopping."

Q. We have just done the amine challenge with our children. My three-year-old daughter reacted but my son actually improved. How can this be?

A. It is not unusual for non-responders to improve during challenges. There can be three reasons for this: 1) normal improvement over time. Improvements on this diet will continue for about 9 months if the diet isn't broken eg by challenges 2) Challenge foods such as bananas and chocolate have replaced small "treats" or mistakes with problems such artificial flavours. 3) Avoidance of a staple which has been causing problems, eg a boy who improved dramatically during the dairy challenge because he had been reacting to soymilk.

Q. I have a child - not diagnosed - with some behavioural problems. Currently I am working with his doctor using behaviour management and his teacher using diet to try to tone down or eliminate the behaviour problems. Any tips or dietary recommendations would be appreciated.

A. I presume your son's teacher has noticed the effects of foods on your son sometimes. Artificial food colours generally cause the most obvious problems. However, if your son reacts to colours, then he probably also reacts to a wide range of other food chemicals with effects which are more subtle, delayed and difficult to identify. I would immediately remove the bread preservative calcium propionate (282) from his diet (you also have to avoid whey powder, which is a natural source of this additive). Brumbys bread is safe if there is one near you and I believe Sunicrust makes preservative-free bread. Have you heard of salicylates? If not, I suggest you read my book "Fed Up", available in most libraries and bookshops, and in particular, have a good look at chapter eight, "What's wrong with fruit and other healthy foods?" Salicylates are natural chemicals in most fruit and some vegetables, which can cause behaviour problems in about 75% of children with irritability, restlessness, inattention or difficulty falling asleep. Hard to believe but true, as this mother reports: "Since purchasing your book "Fed Up" and reading through it last week I immediately cut back my 5 yo daughter's intake of fruit to approximately one quarter of what she would normally have. By the weekend we already saw huge changes in our girl. Her behaviour was more evened out (not so many HUGE highs and lows) and just more sensible, obliging, less aggressive and defiant - just a much more pleasant girl altogether."

Q. How am I going to do the amine challenge? I'm sure my kids won't eat dark chocolate.

A. Buy some Nestle dark chocolate Choc Bits in your supermarket baking section. I will be very surprised if your kids don't eat those. They need to eat about 60 grams a day. You can make the lunchbox choc chip muffins, Fed Up page 230, as a loaf (put in extra choc chips and bake for one hour) and slather it with a thick layer of chocolate icing, using pure cocoa powder and pure icing sugar. With challenges it is terribly important to eat enough, right from the start. If you don't use chocolate the results are likely to be confusing. As well as chocolate, eat at least 2 ripe bananas a day. Bananas go well in milk or soyshakes or frozen on a stick and dipped in homemade chocolate sauce, or in banana cake. Don't forget you can also eat tinned fish like tuna in springwater, lots of gravy with roasts and pawpaw, which also goes well in milkshakes. Reactions are often delayed, day 3 or later. Stop as soon as you see a reaction. If you are not totally sure because of other factors like bullying, wait for three good days and start again.

Q. Shallots in WA shops are small brown onions which look like pickling onions from the outside but inside are pinky white- are these ok ?

A. The shallots we mean are like thin leeks, green at the top and white at the bottom but with no onion-like bulb. In the US they are called green onions, in some states spring onions.

Q. My 5 yo son has been invited to a birthday party at Macdonalds. What do you recommend?

A. You might like to try this reader's approach: "My son is in kindergarten and has been invited to three Macdonalds parties this year. At the first one he ate everything and it resulted in hyperactive behaviour and tantrums. For the next two he ate only the chicken nuggets, chips and drank water. I supply the lollybag, and tell him not to eat the icecream cake - which seems fine with him. We haven't had a problem with this." Some children will react the next day to the antioxidants in the oil. Minimise the amount he eats by feeding him just before he arrives. Then what he will eat most of is your approved lollybag, and he will be happy about going to parties.

Q. I am curious as to what kind of behaviour a 2 1/2-year-old child might exhibit due to an intolerance to some foods?

A. The most common behavioural effects of food chemicals are, in this order, irritability (touchy, easily annoyed, short fuse), restlessness, inattention and sleep disturbance (difficulty settling to sleep or frequent night waking). Quoting from the 1994 study by Rowe and Rowe (see references on website): "The younger children (aged 2 to 6) had constant crying, tantrums, irritability, restlessness and severe sleep disturbance, and were described as "disruptive", "high as a kite", and "out of control". Their parents were exhausted through lack of sleep and the demands of their children who were unable to be comforted or controlled." Children are not necessarily hyperactive, as you can see this story from a reader in Victoria: "I was referred to your book by a friend who had great success with her overactive son. I too have had success, however my 4-year-old boy has always been the opposite. He was always tired and grizzly. He would get upset easily if he couldn't do something and would rarely amuse himself. I also had to put him to bed at the right time or he wouldn't settle and would wake between 5 and 6 o'clock. He would also wake up very cranky and require his breakfast straight away but wouldn't eat much. It was very difficult to persuade him to do what we would like. It caused a lot of friction in the family and I would often hate him … Now he is a changed boy. He sleeps in until nearly 7 o'clock, wakes up in a good mood and doesn't demand his meals straight away. He is very happy and co-operative and his appetite has increased immensely. He originally scored a 50 on the Fed Up scale and now only rates a 5.''

Q. I was reading through your list of common mistakes and was shocked by "confrontational parenting/teaching". This I'm afraid may well be me and at present, my son's teacher. I thought we were doing so well with the diet, he seemed to be much better at home however, his mid year report showed a worsening in behaviour and the comments were fairly destructive. What exactly is confrontational parenting/teaching ? I feel I am missing something and this may be it.

A. When children are oppositional and defiant, a negative, angry cycle of arguments, screaming, prohibitions, criticism and punishments can become almost the only way in which parents or teacher and child relate. They bring out the worst in each other. The key rules of managing oppositional behaviour are to remain calm, to avoid conflict and confrontation, to avoid backing children into a corner and to emphasise rewards and positivity. Parents or teachers may need advice on how to break the cycle by finding areas of common interest (for example, a father may invite his son to go fishing with him and discover his son enjoys it.) This can provide a warm and enjoyable experience shared by both as a basis for change. This is much easier to do once diet has been implemented successfully, but you still have to take the steps to reverse the cycle. An authoritarian teacher who seems to be "picking on" your child can ruin the effects of the diet at school. Sometimes a change of teacher or school is required. You can read more about this topic in "Different Kids" especially p224 (point 2), and the following articles on the website under Order in the House: Self esteem (article about teachers), issue 14, front page; A calm approach to oppositional teenagers, issue 17, front page; and Oppositional Defiance, further down in issue 17. For children under 13 it is also worth watching the video "1,2,3-Magic" (you can borrow it from the LD Coalition, phone 02 9540 3300). For older primary and teenagers, the Lavoie video "When the Chips are Down" is excellent.

Q. I tried phoning a dietitian but she told me she didn't really like to do elimination diets. I was wondering what to do next?

A. Where do you live? We may be able to recommend a sympathetic dietitian for you. Or you can phone all the private dietitians in your phone book plus the hospital dietitians to see if there is anyone who will supervise the Royal Prince Alfred Hospital elimination diet. If not, we can give you the email address of a dietitian who will do email consultations.

Q. I find it difficult when we are out somewhere and the kids start the "I'm hungry, Mum" whine! What can they have if we are at the movies or out shopping for instance?

A. Some suggestions for movies: buy spring water or soda water and take your own food - Pascall's white marshmallows or Kettles chips. Some kids can manage violet crumble bars if they do not react to amines. Handbags or the pockets of cargo pants are good for smuggling food or you can write for permission to bring your own food. Suggestions for shopping: preferably, don't take the kids. Or feed everyone before you go. Or take a packed lunch, eg homemade chicken and salad sandwiches (lettuce, chives, FAILSAFE mayonnaise, beetroot as a treat, salt), hardboiled eggs, homemade cookies. Or you can buy spring water, Kettle chips, Pascall's white marshmallows, fresh rolls from Brumby's or Baker's Delight, celery juice from a juice bar (with half a carrot as a treat), So Good Soyaccino, cup of decaf coffee, Glengarry shortbreads, grilled fresh fish and a tiny serve of chips to share, steak sandwich with no extras - only bread and steak, order a plain BBQ chicken and take your own preservative free bread, have a picnic in the park. This all gets easier as you go, but there are some excellent tips about how to deal with whining in the video 1,2,3-Magic. Some toy libraries have it, otherwise you can borrow it from the LD Coalition, phone 02 9540 3300.

Q. I have observed that small amounts of salicylates seem to disrupt my child's ability to regulate his blood sugar. Is this possible?

A. As far as I can see this is not documented in the medical literature but I have observed the same effect in my daughter. She can even suffer from attacks which are like a diabetic hypo, particularly induced by exercise, overheating or shock (eg from an accident). The attacks can include weakness, lack of cooperation, belligerence, swearing, mental confusion and paranoia. Normally she is not like that at all. They come on very quickly and can improve equally quickly if she eats a spoonful of sugar, which she normally resists while in that state. This is described in my book "Different Kids". She also reacts behaviourally to sugar while eating salicylates. If we avoid salicylates,a dditives and flavours, she has no problems with sugar.

There is a condition called ketonic hypoglycemia which was relatively common in children 20-30 years ago, when children were often given aspirin (salicylates). The condition became very rare when aspirin was no longer recommended for children. One of the children in our network was recently diagnosed with it The treatment of glucose polymer caloric supplement throughout the day as well as FAILSAFE foods made a huge difference to him.

The only other medical journal article I've found about a possible salicylate-blood sugar connection was written by a marathon running doctor. His paper describes collapse during a marathon which he attributes to the interaction of aspirin for a knee injury plus exertion and overheating, the point being that he had run many marathons before and taken aspirin before but never both at the same time. He concluded that the interaction contributed to his collapse.

Q. I am looking for bought lollies that I can use for my sons birthday. I have looked for all lollies mentioned in Fed Up (in several shops) but apart from Pascalls vanilla marshmallows I cannot find anything. Darryl lea white jelly beans have lemon oil in them so that may be why my son has reacted badly to them. I phoned up Snows confectionery to find out what is in the 'flavour' listed on their packets is. They said "it is a trade secret". Could be old boot polish for all I know or something worse. Many packets of lollies do list 'flavours' on the packet. Would these be FAILSAFE? My son's birthday is next week and I really need to know if there is anything left that is FAILSAFE. Could you please help me with this?

A. I share your frustration. It would be so easy for manufacturers to make a wide range of additive and flavour free delicious caramels, toffees, butterscotch, barley sugar, caramel fudge, and milkbased lollies, but they don't. Darryl Lea butterscotch and honeycomb crunch are FAILSAFE. After that it gets more difficult. If the label says flavours (even natural flavours) then some children will react, especially if they eat more than one. Many children react to the white jelly beans permitted by RPA, so I no longer recommend them. If your son can manage amines, you can try Violet Crumble Bars. My daughter can manage only a few Werther's Original Butter Candies because of the flavours, same with Moo Choos. Allen's milkshake lollies seem fairly safe. We used to get Fantails or Chocolate Eclair lollies for lolly bags - a few for our kids and lots for the guests. If you look around local shops sometimes you can find caramel fudge made without flavours. White fairy floss (cotton candy) is FAILSAFE if you can find a person willing to do it. One of the schools here hires out a machine and an operator but you'd have to have a pretty big birthday party.

Q. Can this diet not work?

A. There are many mistakes which will cancel the benefits of the diet. The most common problem is too many mistakes. Next is too many salicylates, often in the form of pear juice, or snack packs of pears in natural juice, or pears which are too hard, too many pears or pear jam. Or too many treats, like white jelly beans, Kellogg's Rice Bubble Treats or too much 7UP. Some people are better off avoiding these. If you have to drink 7UP, less than one glass a week is best. For young children, mint-flavoured toothpaste or chewable vitamin tablets are enough to ruin their diet. Added "flavours" in processed foods like sweets or yoghurt can be too much. Antioxidants (310-321) in oils are a common problem. Any commercial food which contains vegetable oil is likely to contain these additives and they don't have to be listed on the label, eg biscuits, snack foods, fish and chips. Commercial chickens are usually cooked with MSG and other flavourings on the skin. This affects the meat. There are many complaints of reactions after Red Rooster meals or BBQ chickens. Some people need to avoid extra foods such as dairy foods, wheat, gluten or soy. Watch out for non-food factors like perfumes, or cleaning chemicals, new carpet or new car smells. Illness and prescribed medication can cause extra problems. Stress can also cause the diet to fail. A child or adult who is angry or forgetful cannot be expected to become a cheerful high achiever in an authoritarian, punitive, hostile atmosphere at home, school or at work.

Q. Do you think that everyone should try this diet?

A. This is a hard question. You should only try the diet if you have a problem, but I have seen many people who didn't realise they had a problem until they did the diet because of another family member - and found that they felt much better. If there is no one in the family with migraine, itchy skin rashes, asthma or irritable bowel symptoms, it is probably worth just cutting out additives for three weeks, then reintroducing them. But it is almost impossible to avoid additives unless you really know what you are doing. One of the advantages of the elimination diet is that it is basically a three week course in how to avoid additives. A good compromise is to do the elimination diet but to include unlimited fresh fruit and vegetables. The result is additive-free but quite luxurious from the point of view of someone who is doing the diet strictly.

 Q. I have been wondering since reading your book if my son may have always been intolerant to foods, even my breastmilk. He had skin rashes/eczema in the first weeks of his life and was a very difficult baby (reflux, colic) until I stopped breastfeeding him. At the time it was felt that this was because I had enough milk for two babies and very heavy let down that this little baby was trying to guzzle! I wonder now if he was so unsettled because I was eating foods he reacted to.

A. Food chemicals including additives and salicylates can go through breastmilk to affect a food sensitive baby with any reactions from the range of food intolerance symptoms including itchy skin rashes, irritable bowel (colic, reflux), irritability, restlessness, difficulty falling asleep and frequent night waking. I wish I'd known about this when my kids were babies (see "Different Kids", chapter 1).

Q. Having just finished reading your book "Fed Up" this morning (great thing to do on Mothers Day), and then rushing around the kitchen to look at the ingredient labelling on many of the foods we eat, I felt that I must e-mail you promptly to ask if you know of any elimination diet friendly dietitians in and around Fremantle, Western Australia???

A. It is very difficult to find elimination diet friendly dietitians in WA, particularly around Perth. I would love to hear from any interested dietitians! Failing that, we can recommend a dietitian who will do consultations by email.

Q. I was wondering if you could offer any suggestions as to how to get my son to take the 'antidotes' you suggest. He's not able to take tablets yet and I 'wore' the bicarb I tried to get him to have!

A. Bicarb tastes horrible. You can buy some Caltrate tablets (at any pharmacy), crush up a half and serve it in a spoonful of golden syrup or pear jam. The limit per day is 2000mg for adults, so halve that for children. One tablet contains 600 mg.

Q. We have found that our daughter, who has a mild case of ADHD, may be having some reaction to different food colourings and flavourings. We have noticed that every time she stays with her grandmother, who feeds her Froot Loops, she is unbearable. We are looking at the elimination diet and hopefully she will improve. We explained to her why we are doing this and she seems to be quite co-operative with it. Now it is waiting and seeing time.

A. Froot Loops no longer contain artificial colours, although they do contain natural yellow colour annatto 160b which is one of the Big 50 additives known to cause problems. Your daughter's behaviour might also be triggered by the other flavours and colours in Froot Loops which contain salicylates.

Q. Our children aged 6 and 10 yrs become uncontrollable after eating some foods, we had previously put it down to being sugar. Can you see any other links between cordial (pale colours as we have always been wary of colouring), apple juice (no preservatives listed), muesli bars, chocolate and lollies? The reactions are almost immediate with the children going "hypo".

A. The link in all these foods (including chocolate if it contains fruit or mint flavours which many do) is salicylates. Most people have a slow delayed reaction to salicylates but there are a few who react straight away. Or you might be misinterpreting the reaction by looking at the food last eaten when they are really reacting to something they ate yesterday, or "going over the top" because of the cumulative effect. The only way to find out is to do a proper elimination and challenge. It took me six years to understand salicylates:

  • All plants produce toxic chemicals to protect themselves from insects.
  • Some humans are sensitive to these.
  • The most widespread toxic chemicals in plants are salicylates.
  • Aspirin is a member of the salicylate family.
  • The average daily Australian diet can contain almost as many salicylates as an aspirin tablet. This is enough to affect people with salicylate sensitivity.
  • There are some people who can't tolerate any amount of salicylates.
  • In salicylate-sensitive families, salicylates are more likely to cause problems than any other food chemical.
  • Most aspirin and salicylate sensitive people (perhaps more than one million Australians) are not aware of their sensitivity.
  • Salicylates occur in some fruits, vegetables, nuts, seeds, spices, herbs, processed foods containing these foods or fruit flavours, herbal medicines and vitamin tablets.
  • People who react to salicylates will also react to some additives such as colours, flavours and preservatives.
  • Salicylates can provoke a very wide range of problems including (but not only) itchy skin rashes, irritable bowel, asthma, arthritis, difficulty settling to sleep, irritability, restlessness, hyperactivity, headaches, tinnitus, impairment of memory and concentration, depression, panic attacks, epilepsy and anaphylaxis.

Q. After four weeks on the elimination diet, I gave my kids one Usana children's chewable vitamin pill (Usanimals) each. All four kids reacted for a week, like "silly cats" - silly, jumping around, wouldn't listen, couldn't concentrate, fighting with each other. The little ones were the worst. I couldn't believe it, how could one tiny little pill be so bad?

A. Usanimals, like all children's chewable vitamin supplements, contain flavours, usually strong natural fruit flavours such as cherry, raspberry or orange, which are very high in salicylates. This also applies to flavours in children's antibiotic and painkilling syrups. Food sensitive children nearly always react to these. As well, some vitamin preparations contain bioflavonoids or herbal supplements which are a potent source of salicylates.

The only recommended FAILSAFE vitamins are Macro M, Amcal one-a-day, and MVM (not the children's chewable) multivitamins, and plain white Vitamin C tablets. Adult capsules can be emptied and white tablets can be crushed and served in a spoonful of golden syrup or rice syrup (half dose for children). The same with antibiotics and painkillers.

Q. There is a new herbal supplement in the USA which is supposed to really help kids with ADHD. Is it FAILSAFE?

A. Herbal supplements all contain salicylates. Sometimes the benefits outweigh the disadvantages, usually not. If you want to use a supplement such as Efalex, then you can test it in a careful challenge after you have finished your elimination diet. Wait for three good days in a row, then take the maximum dose every day for 7 full days while sticking strictly to FAILSAFE foods. Keep a food/symptom diary. If there is a strong reaction, stop the challenge. After 7 days, review your diary entries and decide whether the supplement is making you better, worse, or no change.

Q. Does the failsafe diet work for people with Aspergers or autism?

A. Yes, but as well as failsafe you should try glutenfree and dairyfree. Then do your challenges. There are a number of ASD children in our network. Some have come to us already doing an GFDF diet. They usually find it is worth looking at salicylates and amines as well, for instance, this mother: "your advice was wonderful. My daughter is on a gluten/dairy free diet for her autism. I had been cooking coconut bread (from a recipe given to me from the USA). You told me about coconut being a 'no-no' because of the salicylates. Well I decided to challenge. Wow, what a difference. Things keep on getting better. I still have a lot to learn!!!"

Q. My son is now 8. He was diagnosed with ADHD when he was 5. He has been on Dexamphetamine, Ritalin, Catapres, Melleril and many others. He has not been on any medication for some time now. He developed tics at about the age of 6, which he still has. Will this diet also help Tourette Syndrome? All the doctors and specialists I have seen told me that the elimination diet does not work. Well, after what we all have been through, I am at the point where I feel the doctors aren't helping us at all.

A. Tics are definitely food-related in some people. Families in this network report that tics reduce and may go away altogether while on failsafe foods but will return when children break the diet, or late at night when very tired.

Q. Does diet help with sleep apnoea?

A. As far as I know there is no connection recognised in the medical literature, but we have received reports of sleep apnoea disappearing completely while on failsafe foods, and returning during transgressions (so far reports of yum yums and some preservatives).

Q. Is there a link with diet and ADD in adults?

A. This question was asked recently on our email discussion group. A surprising number of members responded that yes, they were ADD adults controlled by diet.

Q. My husband sometimes gets pains in his left arm, spreading up to his shoulder and in the region of his heart. Of course, the first thing we considered was heart attack but when he goes to hospital they can't find anything wrong.

A. There is a report of an incident like this 30 years ago during a study of the effects of MSG (Schaumberger, 1969). One of the volunteers who was a GP took himself to hospital with a possible heart attack. He later realised his symptoms were triggered by MSG. We have received two similar reports of emergency trips to hospital hours after dinner in a Chinese restaurant, only to find nothing is wrong.

Q. I am alarmed about a story on the internet about a teenager in the USA who died while taking Ritalin. My son took large doses of Ritalin for years until we started on the diet. Now he only takes one or two a day while studying.

A. The 14-year-old died at home while playing on his skateboard. The medical examiner found the cause of death to be cardiac arrest secondary to blockage of coronary arteries that supplied blood to his heart. Such changes in the blood vessels are not ordinarily found in children so young. It's well known that amphetamine and cocaine affect the coronary blood vessels and the heart itself. The Michigan autopsy found pathological changes in the boy that match those of amphetamine and cocaine abusers. The boy had been taking Ritalin for attention-deficit hyperactivity disorder prescription for 10 years, since the age of 4. The medical examiner believed that no other reason could account for the changes in the child's heart. At least two other children who were taking Ritalin have recently died, in Texas and Ohio. These cases will now be investigated further. Ritalin has been used for more than 40 years for children with ADHD. But until the 1990s treatment for more than five years was unusual. Now many behavior experts are recommending lifetime stimulant treatment for ADHD and more children are taking Ritalin into adolescence. Doctors recommend that any ADHD teens complaining of heart symptoms should be assessed by their doctor and possibly referred to a cardiologist for a more complete exam and a stress electrocardiogram.

Q. Is aspartame FAILSAFE?

A. Aspartame and other artificial sweeteners are not permitted on the RPAH elimination diet.

Approved sweeteners are white sugar, brown sugar, icing sugar, caster sugar, golden syrup, glucose syrup, rice syrup and pure maple syrup. Although FINA has never received complaints of food intolerance reactions to aspartame, there have been overseas reports of itchy skin rashes, headaches and children's behaviour problems. We have, however, received a number of complaints about serious aspartame addiction. These consumers may drink up to 15 cans a day of aspartame-sweetened drinks, representing a can an hour while awake plus one or two in the middle of the night. Obesity can also be problem. People who consume large quantities of aspartame may gain weight rather than lose it. Aspartame's effect of increased appetite, which defeats the whole purpose of a low-joule sweetener, is reported in the Lancet (1986). The best reason of all for avoiding aspartame is a possible association with brain cancers, which have been increasing in children and adults in westernised countries during the period that aspartame has been available on the market. Olney's studies with rats (1996) showed that rats fed aspartame developed a higher rate of brain cancers than those not fed aspartame. A study by aspartame manufacturer G.D. Searle to test the toxicity of diketopiperazine, a metabolic by-product of aspartame which may be responsible for brain tumours, found that both experimental and control rats developed a 16 times higher rate of brain tumours than average. The Bessler Report on an FDA investigation of Searle laboratories noted evidence of failure to maintain and feed control and experimental animals separately. It is possible that both groups were eating aspartame-containing feed. The FDA did not act on this report or other scientific evidence urging caution before approving aspartame for public use. (See references in Fed Up, p 127-128, 339)

Q. According to your shopping list, Kellogg's Rice Bubble Treats are permitted. But my son reacts to them.

A. Some children are more sensitive than others. Any food listed as "limited" may affect some children. My daughter also reacts to Kellogg's Rice Bubble Treats. She says when she eats even one, it sets up a craving so she'd rather not have them in the house.

Q. We did the diet strictly for 2 months with our 10-year-old son. There was absolutely no change. What did we do wrong?

A. The most common reason for failure to improve is tiny frequent mistakes. If there is no improvement at all within 10 days, it is worth contacting your dietitian, or our email support group to check for mistakes. The other, less common, possibility is a small mistake only once a week (eg a seasoned chicken, one ordinary sausage, too much parsley) for a type 3 responder (slow to react, slow to recover - up to a month in some people), so improvement never happens. The most common mistakes are listed below:

  • Pear juice or pears canned in juice instead of syrup. Those handy little containers of pears in natural juice, which fit into lunchboxes, will cancel the benefits of the diet.
  • Too many pear products, fresh, tinned, pureed, jam and ketchup. There is a limit of two pears pears per day, less for some people, note that pears must be soft
  • Too much parsley - use for colour not for flavour
  • Too many Darryl Lea white jelly beans (limit of 4/day but many children are better with none)
  • Too much 7UP (less than 150 ml/week) or Peter's Lemonade Icypoles (1 per week)
  • Cold-pressed oil, even canola - the only safe cold-pressed oil is soy
  • Coloured or mint-flavoured toothpaste
  • Antioxidants, not listed on the label, in any biscuit which contains 'vegetable oil'. Ritz and Jatz often cause problems. Low-fat crackers such as water crackers, Saltine and Saos contain less oil, but the more you eat, the more likely you are to react
  • Hot chips and potato crisps (eg Arnott's Lite) cooked in oil with antioxidants
  • BBQ chicken with seasoning or stuffing - it is NOT OK to eat the meat and avoid the skin or stuffing
  • Flavours, even natural vanilla, will affect some children, eg in vanilla soymilk, flavours in commercial custard and yoghurt but watch especially for flavours in caramels, toffees, lollies
  • Natural or artificial fruit flavours in vitamins or children's syrup medications eg such as paracetamol and cold medications, flavours or colours in antibiotics. We have many reports of people with presumed antibiotic intolerance that is really a reaction to the coloured capsule. Ask if you can empty the capsule contents into golden syrup or a glass of water.
  • You may need to exclude more foods, like dairy foods, wheat, gluten or soy
  • Some people do better on free-range eggs, or no eggs.
  • Some people are sensitive to citric acid or cashews (not common, but it happens)
  • Exposure to chemical fumes like paints, household cleaners, workplace chemicals, aerosol deodorants, cosmetics, garden pesticides, weedkillers, new carpets, mattresses, shopping malls, service stations
  • Sometimes there is a non-food cause like too much stress, confrontational teaching styles, or even a need for more praise from parents

Q. How can I find a dietitian?

A. There are free dietitians in hospitals and community care centres, and private dietitians are listed in the yellow pages. Ask for a dietitian who has experience in supervising the Simplified Elimination Diet from Royal Prince Alfred Hospital. Your best bet is a dietitian who has visited RPAH for an inservice. Good dietitians should give you a set of two booklets from RPAH plus an a set of corrections (1998) or a shopping list (1999). They should also be prepared to answer questions by phone, and refer to RPAH if they don't know the answers. If your dietitian is unable or unwilling to answer questions as they arise, you might like to join our email support group (send request to sdengate@ozemail.com.au).

Q. We have always bought in bulk, exploiting a rather large freezer in the basement. It makes economic sense, and saves us time too. Who would have dreamed this policy might aggravate my children's conditions?

A. Other families with large freezers have reported problems for amine responders. Meat should be frozen the day you buy it and used within a month.

Q. I notice you mark, as salicylate, many items that feingold.org does not, such as pineapple. Perhaps you avoid even the smallest traces? Feingold does this too, in their special SAS diet, but I've never looked at that one.

A. Pineapple is definitely not a small trace. It is the salicylate equivalent of dynamite, but yes, we do avoid even small traces. I believe the SAS diet is the same as ours regarding salicylates. Most people have no idea how sensitive their children are to salicylates until they avoid them all. Some children react even to pears. I have seen desperate families exclude dairy, gluten and soy when the only problem was salicylate sensitivity, plus additives of course.

Q. Between salicylates and amines, are there any fruits left?

A. Only pears, they have to be peeled, ripe soft and juicy (limit 2 per day), or canned but only in syrup not in natural juice because the juice usually contains peel which contains salicylates. This is not forever, but until you find out which foods are a problem. After challenges, small quantities are reintroduced systematically to build up tolerance.

Q. We use to use lemons all the time, as a form of salad dressing, since we can't trust anything from a bottle. Do you have any other dressing ideas?

A. Try Robin's dressing:

¼ cup maize cornflour

3 tsp citric acid

1 tsp salt

½ cup sugar

1¼ cups water

2 eggs

175 ml canola oil

Cook together cornflour, citric acid, salt, sugar and water. When thickened, pour into blender and while whizzing add eggs and drizzle in canola oil. Keeps well in refrigerator for approximately two weeks. (with thanks to Robin Fisher)

Q. Like fruits, virtually all nuts seem to be bad. Are there any good ones?

A. Raw cashews are limited to 10 per day

Q. I know cheese is a problem but what about dairy foods like milk, butter and pure icecream?

A. Some children react to dairy foods, some don't. If there is a history of frequent ear infections, grommets, or lactose intolerance, it may be necessary to avoid all dairy during your elimination diet and do a systematic challenge as soon as you have obtained five good days in a row. All healthy foods must be challenged according to the protocol so that you are not avoiding them unnecessarily. If dairy foods are not suspect, then plain milk, fresh white unpreserved cheeses (like ricotta and cream cheese) butter and pure ice cream (eg Sara Lee rich vanilla) are ok. Vanilla yoghurt can be ok, limited, but watch out for annatto colour (160b).

Q. Most natural sugars are ok, but what about corn syrup?

A. Corn syrup contains small amounts of salicylates, as does raw sugar & cane juice

Q. Since sunflower seeds are high, how about sunflower oil for cooking?

A. The only recommended oils are sunflower, safflower and canola, not cold pressed and free of antioxidants (gallates and TBHQ, BHA and BHT). Cold pressed soy oil is OK, the others have too many salicylates in them.

Q. How long can cooked meat or fish sit in the fridge before it becomes a problem?

A. The same day, but preferably leftovers should be frozen as soon as possible. Note that fish should be frozen within 12 hours of being caught and eaten within 2 weeks.

Q. Do the comments about chicken (skin livers etc) apply to all poultry, such as duck and turkey?

A. The stronger the flavour, the more amines, so approach duck with caution. Turkey is FAILSAFE but of course can't be selfbasting or all those other things they do to it.

Q. These restrictions can make for some rather bland meals, if we can't use some spices. Which ones are ok?

A. Garlic and salt, nothing else. Nothing is bland if you use garlic! You will find your taste buds adapt very quickly and food tastes stronger and better than ever. You'll wonder why you ever needed all those strong flavours. Most people find processed food is far too strong after they have eaten FAILSAFE food for a while; their taste buds had previously been seduced by the food industry.

Q. How about rutabega? This is in the same family as broccoli and cauliflower, so I thought I'd ask.

A. We think that this is what we call swede, which is OK. You can't go by food families. Broccoli and cauliflower are out, cabbage and brussel sprouts (same family) are FAILSAFE .

Q. How about soy oil, or, partially hydrogenated soy oil. The latter is in many commercial products, even the purest products at the healthfood store.

A. Soy oil is OK, see conditions above, but we always have to phone the manufacturer to find out whether it contains BHA or similar because it does not have to be listed on the label.

Q. How long can eggs sit in the fridge before they form amines?

A. Most people can manage eggs, except for those with a true egg allergy (less than 1% of adults, less than 3% of children under 5). Sensitive people can react if the eggs are obviously stale. Some people manage free-range eggs better. Also it depends what the chickens are eating. Some sensitive people react to the feed that is now used to make the yolks orange.

Q. I know canned fish/meat is a problem. Is this because the proteins age or something to do with canning?

A.
