Q. I regard potatoes more as a starchy carbohydrate than a vegetable and wonder if my son has too many.

A. Often called uber tubers, potatoes contain all the vitamins, minerals, proteins, calories and cellulose necessary for life. A healthy adult can survive indefinitely on potatoes alone. A potato crop can grow in any climate and can yield four times the calories of a grain crop. (http://books.guardian.co.uk/review/story/0,,2263286,00.html). Jamie Oliver lists potatoes as the top crop for home gardeners: 'Everyone deserves to experience home-grown potatoes - what a pleasure!' To be low in salicylates, potatoes must be large, old, brown skinned, white fleshed and thickly peeled. Potatoes that are small, new, red skinned or have coloured flesh - even cream colour like Kipfler - are higher in salicylates.

Q. I seem to have troubling neurological symptoms due to Rosemary Extract, commonly used as an antioxidant in almost all vegetable oils. The amounts are so small as to avoid labelling laws, yet enough to upset a sensitive soul like myself. Even rabid herbalists concede rosemary can cause gastric and neural problems in some people. Are you aware of any reports on reactions to rosemary? 

A. Rosemary extract would be very high in natural food chemicals called salicylates. These chemicals occur in most plant foods in varying amounts and can cause the same problems as additives if consumed in large doses or by sensitive people, see our salicylate factsheet. Compare the following figures from Swain et al's 1985 paper 'Salicylates in Foods': pears 0.00 (mg per 100 mg); carrot 0.23; strawberries 1.36; sultanas (dried white grapes) 7.80; cinnamon powder 15.20; rosemary (dried) 68.00.

Q.I have just started my son on the elimination diet, he is in the 3rd week and we have slowly seen some improvement.

A. By the end of the 3rd week most people see spectacular improvement if they have the diet right. Have you read the Checklist of Common Mistakes on the website? You are welcome to send me a list of everything your son eats in a typical day so I can look for possible mistakes. I can usually find about five mistakes - some serious enough to prevent improvement - in food lists from people who swear they are sticking strictly to the diet.

Q. I am finding it hard to come up with enough variety of foods for my son as he is very fussy and this seems to limit what sort of foods he can eat. Do you have any suggestions?

A. Fussy eaters usually improve when you get the diet right. One mother whose two young daughters had previously been picky described how they turned into 'clean plate' eaters after three weeks on the diet. For suggestions regarding a variety of foods I recommend the Failsafe Cookbook. One mother whose son was lunch swapping wrote: 'I was able to buy your cookbook, so now he is getting enough interesting things and variety that he feels he is not missing out!'

Q. Since we started our elimination diet I have been experiencing a lot of diarrhoea, at one point, every day for a week. I thought maybe it was a withdrawal reaction, but it has continued. I have stopped my 2 blocks of chocolate a day habit and to get me through I am using xylitol which the homeopath said was completely safe. Is xylitol not recommended as a sugar substitute?

A. Xylitol is not safe for some people. It doesn't cause the full range of food intolerance reactions such as behaviour or headaches, but any of the sugar free sweeteners ending in '-ol' (e.g. Sorbitol, Mannitol) can cause diarrhea and irritable bowel symptoms, especially if eaten frequently. See our Sugar Free Sweetener factsheet for more details.

Q I've noticed that my brand of contraceptive pill has artifical colouring. I really don't want to be consuming this every single day! Do you know of any brands of the contraceptive pill that are failsafe or where I might find out?

A. Contraceptive pills aren't great for women with food intolerance because female hormones can make symptoms of food intolerance worse, i.e. premenstrually and when taking oestrogen in medication. For pills without artificial colour, you can browse through the Consumer Medicine Information (CMI) sheets for ingredients of oral contraceptives at http://www.mydr.com.au/drugs/mediresults.asp.

Q. I bought green grapes two weeks straight – they were so cheap and I haven’t bought them since last year. My son loved them but for those two weeks he was screaming and hitting me and going crazy until I put it together - behaviour + grapes.  I was talking to another friend and she said her daughter was reacting the same way.  We took the grapes away and both the kids calmed down within a couple of days.  There was a warning at the supermarket about sulphur dioxide next to the price sign on the grapes. Is this a common phenomenon?

A. Since the ‘salad bar’ asthmatic deaths in the 1970s due to overuse of sulphur dioxide on lettuce, sulphur dioxide has been banned on fresh fruit and vegetables except for grapes. These days they use sulphur dioxide generator pads instead of sprays. However, growers are warned that high temperatures can cause excessive sulphur dioxide in the grapes. January was the hottest month ever in Australia so sulphur dioxide level could have been very high. Sulphur dioxide (220-228) can cause asthma, behaviour problems, eczema, irritable bowel and other symptoms. Another reader has reported feeling asthmatic since buying similarly labelled grapes. Another possibility would be behavioural disturbance due to high natural levels of salicylates, amines and glutamate in grapes (and sultanas). The more children eat, the more likely they are to be affected.

Q. Would removing the crusts on bread get rid of the preservative?

A. In Australia, preservative 282 is baked into the bread and removing the crusts will make no difference. In the UK, according to a recent article by Ian Tokelove of the Food Commission, the freshly baked loaf of bread is given ‘a light coating of preservative - usually calcium propionate or E282’ (http://www.foodcomm.org.uk/backmags.htm#2007). In that case, it is possible that removing crusts from bread could remove preservative E282. However, I would want to know for sure that all bakers used this system, and that cutting off crusts would remove all the preservative before I would rely on it. Any UK failsafers like to comment? (reply to suedengate@ozemail.com.au with newsletter reply in the subject line)

Q. Can you tell me is bocconcini cheese failsafe? I assumed it was since it is a fresh white cheese.

A. White cheeses such as cottage cheese or ricotta are low in amines and failsafe as long as they are recently made and preservative-free. Bocconcini are small, mild, white, young mozzarella cheeses kept moist by storage in natural whey or brine. Fresh bocconcini are probably failsafe but if kept will develop amines.

Q. We have benefited greatly from failsafe eating. However we are in a newly renovated house and although my son is on the full elimination diet, his behaviour which we discovered to be due to food has now returned to pre-diet due to the effects of paint smells etc. Any suggestions?

A. The best way to deal with new renovation smells is to ventilate - leave all the doors and windows wide open as much as possible and run fans. If there are any smelly removable items such as mattresses or new furniture, you can put them on a verandah or leave them in the garage to gas off. Some people have dealt with this problem successfully by getting their kids to sleep in a tent in the back yard. Or could you stay with someone else for a month or two until the worst of it is over. Formaldehyde (a common VOC in renovations) is a carcinogen so it's not something you want to be exposed to anyway.

Q. My son aged 12 months is allergic to soy. Do you know the number codes for soy derived emulsifiers etc?

A. From a reader who is sensitive to both soy and legumes: “As well as 322 (lecithin) I also avoid additives 476,471,492 (emulsifiers), vegetable gums 410,412,415,416,461 (not all soy but derivatives of various beans), vegetable gums & vegetable protein, TVP (textured vegetable protein) and vegetable starch (even if they do not specifically state soy, I don't take the chance). Soya beans, soya meal, soy flour (very common in breads and cakes), soya sauce, miso, tofu and chickpeas. In fact quite a lot of 'health foods' are grossly unhealthy for me. Packaged health foods nearly always contain a soy additive.” See more details in story [314] “13 years of intolerance to soy” (April 2004).

Q. It is easier for me to buy goats’ milk than A2 milk. Is it the same?

A. Goats milk contains the same A2 beta casein protein as A2 cow’s milk, but it has a different nutritional profile. Babies who have goat’s milk may need extra supplements including Vitamin D and Folic Acid. Your dietitian can advise about this.

(November 2007)

Q. I came across "1422 - thickener" in a packet of frozen meals. What is this please and is it a no no? We really enjoy your informative site.

A. Thickeners are only a problem for coeliacs and others who are very sensitive to gluten. Also called modified starches, thickeners 1400-1450 may contain trace amounts of gluten if they have been derived from wheat. If gluten is in the product, it will be listed on the label.

Q. I would like your opinion on whether fresh coriander is failsafe or not. Also interested in seeing if there is a difference between fresh coriander and ground seed?

A. Technically, fresh coriander is moderate in salicylates. It contains 0.20 mg per 100 mg (compared to fresh parsley leaves with 0.08 and Red Delicious apple with 0.19, according to the Swain et al 1985 analyses). An occasional small amount is probably okay for most salicylate sensitive people, but I recommend caution if using it in a product you eat every day. It is so easy for salicylates to build up when you are not looking. Ground coriander seed was not tested but you would expect it to be much higher in salicylates.

Q. My son’s aggression has been increasing. He has been eating a lot of the new all natural jelly cups, strawberry flavour (ingredients: sugar, thickener (401), food acids (355,331), mineral salt (341), flavour, colour (120).) What do you think, is this jelly failsafe?

A. Those jelly cups are fine for families who are simply going additive-free but they are not failsafe because of the strawberry flavour which contains natural chemicals called salicylates. Salicylates can cause the same problems as additives if consumed in large doses or by sensitive people. Note that colour (120, cochineal) doesn’t cause behaviour problems but because it is made from insects it should be used with caution by children with a family history of food allergy (also not kosher). 

Q  I feel very confused about which is the lesser of two evils - the trans fats in butter (which is listed as 'natural trans fats' - what does that mean???) or the preservative 202.

A. It is the unnatural trans fats that are the problem. We ourselves eat pure butter (Mainland Buttersoft from NZ) and totally avoid 202. We also avoid synthetic trans fats. Nuttelex additive-free dairy-free margarine is low in trans fats. However, we minimise our intake of saturated fats including butter. For example, when baking I will often choose to make muffins or a cake recipe with vegetable oil rather than rather than butter or margarine. For vegetable oil, we use canola oil. It's a monounsaturate with one of the best omega ratios despite scientific-seeming internet criticism probably started by an opposing industry. Olive oil is similar but we can't eat it because of salicylates.

Q. I recently asked our Swedish food safety authorities if they do tests on additives themselves, or do they rely only on the tests done by the producers of the additives? They answered that neither they, nor the EFSA (European Food Safety Authority), do any tests at all. The approval of an additive is based solely on tests performed by the producer of the additive. Isn´t this a bit like asking Phillip Morris if smoking is safe? – Stefan from Sweden

A. It’s even worse than that – before additives are approved there are no tests at all regarding their effects on children’s health, behaviour and learning – and there is no monitoring afterwards. When consumers report adverse effects, they are advised to carry out their own double blind placebo controlled studies.

 

Q. I found the following radio story a bit of a worry: http://www.abc.net.au/news/stories/2007/11/20/2095831.htm  [A leading CSIRO scientist says there is no reason to fear that future gene technology will threaten food safety. Deputy chief of plant industry research, Dr TJ Higgins, says consumers have been using oil from genetically modified cotton for the past 10 years. Most of the fish and chips that we eat are cooked in the oil from cotton seed, and there are 33 other foods have been approved for consumption. "So there are already many products that are in the food chain that we have been consuming safely."]

 

A. We are worried too. Dr Higgins says there are strict regulations to protect consumer food safety, but as we have already seen, regulations about food additives haven't done anything to protect our children. Here's what you can do. This Saturday, vote for your local Green candidate and vote Green in the Senate. The Greens have a strong policy about GM foods, including mandatory full labelling. Of course they won't win, but every vote sends a message and if there are some Greens in the Senate, there is a chance of controlling what happens with GM foods.

(August 2007)

Q. I have just read your fact sheet on 635 (riborash).  It seems that any time we eat a food with this in it (particularly cream of chicken and corn soup used in risotto), my 16 month old gets severe nappy rash.  Could this be a reaction to the additive? 

 

A. Yes. The rash can appear differently in different people. One of the original observations of ribo rash was in twin 10-month-old boys who suffered severe rash in the nappy area and extending down to their feet and on their faces when at its worst.

 

Q. I have been using a saline spray for my son’s seasonal itchy nose with great success. However we have experienced aggressive episodes since using the product (Narium).  I did a double check and found a preservative Benzalkonium Chloride (BAC) is in the product. Have you had any experience with this?

 

A. There have been some reports of nasal burning, dryness, or irritation due to nasal sprays preserved with BAC. There are also reports in the medical literature of contact dermatitis due to BAC. We generally find any additive that can cause the very obvious signs of contact dermatitis may also be associated with more subtle behavioural symptoms such as aggression. It is possible to make your own preservative free saline: a teaspoon of salt in half a litre of water, boiled and cooled. Store in the fridge and discard after 24 hours.

 

Q. Why is sulphur dioxide added to wine?

 

A. According to Erl Happs, maker of the excellent Happs range of preservative-free and low preservative wines, sulphur dioxide ‘hardens the palate’ of a wine, see http://www.happs.com.au/pages/PFQandA.html.

 

Q. Is there a product like muesli bars that can be bought directly off the shelf that is homemade without all the additives?

 

A. Thanks to Jenny Ravlic from Additive Education (www.additiveeducation.com.au) for the following answer: We don't suggest any of the standard packets of muesli bars available in supermarkets because they all have either sulphites, annatto, flavours and/or nasty antioxidants in the oil. There is a great product called Naturally Organic Oat Slice (few varieties) made by the All Natural Bakery. They are sold individually in 100g slices with no artificial flavours, colours or preservatives - very much like a homemade product. There is also the Amore Fruity Nut Bars, sold in multi packs. Both of these are available in Coles, possibly Safeways and IGA. Please note that these suggestions are additive free but not failsafe (low in salicylates and amines).

(May 2007)

Q. What is the best way to stay with the most current info on the salicylate content in foods?

A. See the latest edition of Friendly Food by the Royal Prince Alfred Hospital Allergy Clinic, http://www.cs.nsw.gov.au/rpa/Allergy/default.htm

Q. My daughter suffers from dizzy spells. Specialist testing, from MRI scans to epilepsy, has found nothing. I was wondering if intolerance to certain foods can cause dizziness, I am at my wit’s end as my daughter cannot even close her eyes sometimes at night because her head starts to spin.

A. Dizziness and a spinning head (vertigo) can be related to chemicals in foods and medications. The most likely culprits are: synthetic salicylates in medications such as aspirin, nurofen and other pain killers or anti-inflammatory medications, acne cleansers, wart medication, sports liniments and medicated lotions; artificial colours and preservatives in foods and medications; natural salicylates in most fruit and some vegetables - particularly high in tomato sauce, juice, broccoli, grapes and citrus fruits - (see the Salicylates and Meniere’s factsheets). If avoiding salicylate-containing medications doesn't help, the best way to find out if foods are your daughter's problem would be to do a 3 week trial of the RPAH (Royal Prince Alfred Hospital) elimination diet, supervised by a dietitian. Write to confoodnet@ozemail.com.au for our list of supportive dietitians.

Q. I would like to contact Woolworths with an enquiry about their Home Brand products. Do you have an email address for them?

A. Go to www.woolworths.com.au and click on Contact Us

Q. Since we are off dairy I thought we would have to do an amine challenge without chocolate, otherwise how will we know if we are reacting to amines or the milk solids in the chocolate? 

A. You can buy dairy-free chocolate (read labels, e.g. Sweet William www.sweetwilliam.com.au, contains soy flour and soy lecithin).

Q. Where can I get the dietician’s booklets for information about challenges?

A. Your dietitian will give you one or you can buy them direct from Royal Prince Alfred Hospital Allergy Clinic: www.cs.nsw.gov.au/rpa/Allergy.

Q.  My husband and I are having severe relationship problems, and I'm not sure how much of it might be due to ODD (oppositional defiance). When he is calm and rational and nothing immediate is happening, he seems normal, mature, etc. Says all the right things. But if a situation arises where he is confronted with a problem he seems to react badly. His behaviour is like that of a child throwing a tantrum. I am finding it very hard to cope and have noticed this comes in cycles. This is really difficult for me because it feels like I have 3 children sometimes, not 2 and honestly, our children behave better than he does, and appropriately for their ages whereas he doesn't. The symptoms that really stood out when reading the ODD factsheet were “deliberately annoying other people” (He says he knows he does this sometimes and to the point where he can't stop himself) “blames me for mistakes or problems related to him” (He is very good at this, most of the time I end up wondering what it is that I have done wrong). Living with him is like walking on eggshells. I don't know what might set him off - what triggers him one day doesn’t trigger him the next. He keeps putting off responsibilities and either refuses to do them or puts it off so long that I end up doing it or he is too tired to do it and leaves it for the next day. If I remind him or ask him, he often reacts with anger, resentment and refusal. I'm aware of a few food additives such as tartrazine that trigger aggressive moods in him but I feel there are other things influencing his behaviour. His mother told me recently he was a problem child and on drugs for ADHD. Is this possible - that adults can have ODD too?

A. Yes. The most important behavioural effect of food chemicals is irritability, which is also the core feature of ODD. There are numerous reports of ODD-type symptoms improving in the father or mother when the whole family goes on the diet to support a difficult child.

Q. Recently my husband has awoken with awful headaches after eating a "Healthy Choice" meal which is supposed to be "good for you". One was a stuffed shell dinner and another one was a beef stroganoff meal, which he used to eat without getting a headache. I wonder if they're currently sneaking in things which produce the same thing in him that MSG does; i.e., bad headaches?

A. Since you already know your husband gets headaches from MSG, it is most likely he is affected by some new flavour enhancers that can enhance the effects of MSG by up to 15 times. Here in Australia they are called disodium inosinate (627), disodium guanylate (631) and ribonucleotides (635, a combination of the previous two). In the US, they can be listed with different names such as disodium inosinate (“DSI” or “IMP”), disodium guanylate (“DSG” or “GMP”), and the combination of IMP and GMP (“I&G”); IMP, GMP and I&G are also known as nucleotides. Although these extra flavour enhancers are used to enhance the effect of MSG, MSG itself doesn't have to be listed on the label and often the packet will say "no added MSG" although MSG will be there in some other form such as yeast extract, hydrolysed or autolysed vegetable or plant proteins or even just "flavor".

Q. My daughter who is 3.5 years old suffers from eczema and around the age of about 10 months she went completely bald from Alopecia Areata (she lost all hair on her head, eyebrows and eye lashes), but fortunately the hair started to grow back around 19 or 20 months. However, we are very disappointed to discover the alopecia appears to be returning as a bald patch has recently appeared on the top of her head. I am wondering if you are aware of any food additives which may have triggered this condition?

A. Alopecia areata (patchy baldness) or totalis (total hair loss) has been associated with coeliac disease and may respond well to a gluten-free diet, see http://www.fedupwithfoodadditives.info/factsheets/Symptomalopecia.htm. Coeliac disease is a serious condition, if you suspect you have CD, see more information at www.coeliac.org.

Q. Is strawberry Nesquik OK for a homemade milkshake on the elimination diet?  The ingredients are: cane sugar, maltodextrin, natural colour (120), natural flavour.

A. No. The natural flavour is obviously strawberry. It’s probably in a very strong, concentrated flavour and would contain at least as many salicylates as a milkshake made with real strawberries, possibly much more.

Q. Do you know anything about brilliant scarlet 4R CI6255? It is one of the active ingredients in Polaramine antihistamine tablets. I gave this to my son (10yrs) tonight under instruction from my pharmacist for sedative reasons. My son’s reaction to the tablet was very defiant/angry, definitely did not want to go to sleep etc and we could not reason with him at all.

A. That’s another name for artificial colour (124) also known as Ponceau 4R. It is one of the worst of the artificial colours – known as synthetic coal tar dyes and azo dyes – that have been associated with irritability, restlessness, inattention and sleep disturbance in children, and also with asthma and many other problems such as hives. Children who have a big reaction to an artificial colour are likely to be sensitive to a range of other additives, and salicylates as well. If your son has problems enough to need medication, you might want to try the elimination diet supervised by a dietitian to find out exactly what affects him. You can request our list of friendly dietitians from confoodnet@ozemail.com.au.

Q. Sago pudding is on your recipe list (and we like eating it) yet every brand of sago I have seen so far contains 220. Do you know if it possible to buy sago without it and from where?

A. Howard tested Lion brand sago from Anchor foods with sulphite test strips. This brand lists preservative 220 but Howard couldn’t detect any either cold (uncooked) or when cooked. We also buy Cock brand Tapioca Pearl (really sago) from Thailand which has no preservative listed and tests sulphite-free.

Q. My 5yr-old daughter has been diagnosed with severe food intolerances and a moderate allergy to soy. I do not have the finances to use a private dietician. I went to the public hospital yesterday with no positive outcomes – they can’t offer the service of their dietician as they are understaffed and are not taking outpatient appointments – and I was told to go home and try the elimination diet again. This is hard work on your own. I need some support. – by email

A. I recommended the Failsafe booklet and our email support groups to this mother. A week later, she replied “Thank God for the Failsafe booklet. I am now managing to keep the whole family on the elimination diet due to the extra recipes”. She had also joined an email support group.

Q. We have dairy and soy issues. Is there a substitute for yoghurt?

A. We have been unable to make yoghurt or kefir out of rice milk and have found it only works with soymilk and cows’ milk, due to the protein content. If you can tolerate A2 milk you can make your own A2 yoghurt using sheep’s yoghurt as a starter. If you are asking because you want an alternative to eat, see Narni’s custard recipe in the new version of the Failsafe Cookbook.  If you are asking because of the probiotic effects, an alternative is the Inner Health Plus dairy-free probiotic capsules – these are not on the RPAH elimination diet list so you would have to introduce them as a challenge. Note that there is little scientific evidence for the effectiveness of probiotic supplements other than Lactobacillus GG; however, some people say they help and others report no effect.

Q. After eating a lot of dried fruit we noticed our sons’ behaviour worsened as well as asthma.  Are sulphites also likely to cause hyperactivity and/or aggression?

A. Yes, but they are not the only problem with dried fruit - most dried except pears contain high levels of natural salicylates and some (e.g. sultanas) contain very high levels of both salicylates and amines.  Although sulphites have been associated with a range of symptoms including asthma, headaches, irritable bowel and behaviour, so too have other food chemicals including salicylates and amines. It is worth suspecting sulphites in dried fruit first for asthma, but everyone is different, and you might need to consider any or all of these food chemicals.

Q. Is Aussie mite (vegemite alternative) failsafe?

A. Yeast extracts are never OK because they are loaded with natural glutamates (MSG is a yeast extract) as well as high in salicylates and amines.

Q. Is benzoyl peroxide (for acne) failsafe? My teenage son seems to have had a reaction to it.

A. Benzoyl peroxide breaks down into benzoic acid and is excreted as benzoate, so unfortunately it is not suitable for failsafers. It would be like drinking products preserved with sodium benzoate (211). (Would the person who sent this question please write again as I deleted your email by mistake. S)

(January 2007)

Q. Over the last two months I have consumed 4 bottles of a special juice from the Himalayas. Since taking this product my eyes have become very dry and sore and I had to go to an optometrist who advised I apply a solution to my eyes to get relief. My sister did a little research and discovered that one of the preservatives in this juice is benzoic acid (210), and that side effects of benzoic acid can include eye irritation as well as asthma, hives and hyperactivity. This was a shock to me as I have been taking the juice because I believed it to be beneficial for my health, containing natural ingredients. I would like to know what your thoughts are on benzoic acid and its effects.

A. I agree with your sister. Benzoic acid and other benzoates (310-319) can be associated with a very wide range of adverse effects. Reactions are related to dose and delayed, so the effects will be worse when you are consuming a benzoate-preserved product every day. The effects can build up so slowly you would not be able to notice the connection between a new food and how it is affecting you. You could test this for yourself by avoiding your special juice until your eye symptoms disappear. Then reintroduce the special juice in the same doses that you have been consuming while keeping a diary of your eye symptoms. If you want to test the benzoates without the juice - there is always a possibility that something in the juice itself is affecting you - you could use Schweppes lemonade in cans (contain preservative 211) not bottles (preservative free).

Reply (two weeks later): As you suggested I went off the special juice. It has been 2 weeks now and my eyes have improved 100%. Who would have thought that something like that could do this? Thank you for your reply because if it was not for you and my sister I would probably still be taking it.

Q. I’m confused. On page 16, Friendly Food says shallots are low in salicylates, but the recipes and shopping list refer to “spring onions (scallions)”?

A. These members of the onion family lack a fully-developed bulb and are milder tasting than other onions. I call them shallots but they have various regional names (scallions, spring onions, eschallots, green onions). See what to buy on our DVD, Friendly Food p7 or http://en.wikipedia.org/wiki/Scallion

Q. We're on day seven of our elimination diet for my six-year-old daughter, and every day since we've been on this new diet she's gotten a little worse - more insolent, less able to keep still than normal, much MORE day-dreamy and going off on tangent-ish, slightly 'violent' - absolutely driving me crazy! How long does it take to see positive effects?

A. These turned out to be withdrawal symptoms, and the answer was, it took 8 days to see positive effects.

Q. The website is so handy and I refer to it frequently, but I often get lost looking for a piece of information I know I have read somewhere. A search tool would be very useful!

A. You can search our website using google. Search for: fedupwithfoodadditives <whatever you are looking for>

Q Can you direct me to any research that shows how diet can affect an adolescent with ADHD & ODD?

A. Superintendent Peter Bennett from the West Yorkshire police did a diet trial with 12 chronic juvenile offenders (aged 8-16) who had an average arrest rate of more than once a month. All improved. Those who remained on the diet did not re-offend. These were children whose ODD had progressed to Conduct Disorder, see citation below. You can see this study on our DVD. It is very difficult to do diet with adolescents unless 1) they themselves want to try it and 2) they get support from the community (e.g. school etc). The participants in the Shipley Project had to stay at home in the care of their parents for the first three weeks of their elimination diet. Further reading: Bennett CPW and others, The Shipley Project: treating food allergy to prevent criminal behaviour in community settings, J Nutr Envir Med 1998;8:77-83.

Q. Can the elimination diet help these children: • a four year old girl who can be quite defiant when asked to do something she does not want to do, blames others for her behaviour (mainly her six-year-old brother), is very loud and chatty, and sings all the time when she is not chatting  • a three year old boy son is very defiant, answers back "no", won’t listen to instructions, almost shouts when he speaks and wakes early (5.30am) in the foulest mood?

A. The symptoms described generally improve if you can get the diet right.

Q.  I have a son in his thirties who has been on the diet since the age of 6 (salicylates, preservatives, colours and dyes are the problem, not amines). Unfortunately, he has recently begun getting quite serious depression and is seeing a psychiatrist who just keeps prescribing different anti-depressants as none seem to work.  I recently wrote a letter to the psychiatrist explaining my son’s dietary problems and the symptoms he gets. The psychiatrist told him that all food intolerance is psychosomatic. You can imagine how much help that was. Are there any psychiatrists or counsellors who understand this chemical sensitivity problem? While he does try to stick to his diet, I do suspect there may be too frequent diversions from it or something is catching him out he is not aware of. Trying the elimination diet again is something I think I shall try to persuade him to do. 

A. Symptoms of food intolerance can change throughout the lifespan, and it is not uncommon to find the foods that caused hyperactivity in childhood can cause depression in adulthood. There is case history describing a young adult with a history of childhood ADD whose severe treatment-resistant depression improved dramatically on a low salicylate elimination diet (Parker G and Watkins T, Treatment-resistant depression: when antidepressant drug intolerance may indicate food intolerance, Aust N Z J Psychiatry, 2002). The article concludes that clinicians should be aware of food intolerance-related depression and that it may be worsened by psychotropic medication. You can request our list of supportive health professionals - including some psychologists – from confoodnet@ozemail.com.au. It may be worth consulting a dietitian, as safe foods for this diet change constantly and your son could be following an out-of-date diet. To send the article’s abstract to your son’s psychiatrist, see http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Select+from+History&db=pubmed&query_key=1 

Q. I know it is a mistake to buy anything without checking the ingredients, but the name on the packet of "Traditional Home Style Preservative Free" Egg Noodles sort of lulled me into a false sense of security. These egg noodles contain two artificial colours Sunset Yellow (110) and the dreaded Tartrazine (102)! ... I wouldn't have even noticed if the water I cooked them in hadn't turned a sickly yellow colour! The back of the packet talks about how the family began making traditional noodles back in the 'thirties from a time-honoured family recipe and also says that that the family has a commitment to quality and hand-made authenticity ... isn’t this a bit misleading? I intend to email them to register my disappointment.

A. It is always worth emailing a food company with feedback about their product. Let us know about their reply and if you need any backup. Or nominate it for our Nasty Food Awards – send us the packet or a good photo of the packet and ingredients list.

Q. Because everything on the elimination diet is so 'green' I decided it would be a great idea to get red cabbage to liven my fried rice up a bit! ... problem is (being a novice) I had no idea that the red cabbage would colour the eggs in the fried rice an amazingly rich blue!!! ... lovely but it didn't look so appetizing! Then the next day I was thinking of using the cabbage to colour icing for some 'gingerless pigs'. How do I extract the colour without my icing tasting like cabbage??? ... Also, although I noticed the eggs went bright blue, water left in the bowl with some leftover cabbage in it went a kind of a beetroot 'red'... Just curious as to why, how and whether I can make two different colours out of my cabbage?

A. Cabbage juice will be different colours depending on whether it is acid or alkaline - you can make it acid by adding citric acid (red; that will also take care of the cabbage taste), and alkaline by adding soda bicarb (blue).

Q. I believe my six-year-old son may be affected by food additives as he is erratic, runs, yells loud and then fights with his two older brothers, although he can behave when he wants to. After observing my son, our paediatrician decided that he did not have ADHD nor did the food he eats affect him, instead he said it was my parenting skills. I do not believe this as I have two older boys who do not behave badly. The paediatrician refused to write me a referral letter. I need help.

A. There are a number of ways around this. If you need to prove to the paediatrician that behaviour management isn’t the answer you could do a parenting course such as 123 Magic (many community organisations are now offering this) or see the 123 Magic DVD (there’s a link from our website). You would probably find it very helpful to join one of our email support groups (see EMAIL SUPPORT GROUPS on the website)  You could ask your group or local contact if there is a supportive dietitian who can help you or write to confoodnet@ozemail.com.au for our list of supportive dietitians. Or you could cut down on problem additives and foods such as tomato sauce, citrus and broccoli, see the free downloadable Failsafe Booklet (under FAILSAFE EATING on the website).

Q. Are there any laxatives that can be used during our elimination diet?

A. Your dietitian may recommend one of the following laxatives – though obviously not the coloured or flavoured options:

psyllium hulls or husks - a type of dietary fibre that is used as a bulk forming laxative, the husks swell when they come in contact with liquids so should be taken with plenty of liquids - available from your health food store or as plain Metamucil from pharmacies

Ispaghula husks act in the same was as psyllium, available from your pharmacy as Fybogel

• guar gum - a vegetable gum sold in health food stores as a gluten free baking aid that you can add to muffins, bread etc, or as Benefibre in pharmacies

lactulose - a synthetic sugar available as Actilax from pharmacies

• Epsom salts (magnesium sulphate - do not confuse safe sulphates with nasty sulphites, only for occasional use as a laxative). A bath of Epsom salts is sometimes used to calm autistic children, see www.epsomsaltcouncil.org for health benefits including a claim to ease migraines. Consult your pharmacist about dosage.

• vanilla parachoc.

Q: I have heard that the US National Academy of Sciences concluded in 2002 that the only safe intake of trans fats is zero, and that the World Health Organisation (WHO) has recommended that governments phase out partially hydrogenated oils. In Australia, are trans fatty acids identified on food labels? Is our government taking action to reduce trans fatty acids in food?

A: Trans fatty acid contents must be declared if a nutrition claim is made in respect of cholesterol or saturated, trans, polyunsaturated or monounsaturated fatty acids; or omega-3, omega-6 or omega-9 fatty acids. Some food manufacturers voluntarily list the amount of trans fatty acids in their products. FSANZ is proposing to allow manufacturers to use a claim that a food 'low in trans fatty acids and saturated fat can reduce the risk of heart disease' when they introduce a new regulation on health claims on foods in 2007. This will assist consumers to make healthier choices and encourage the food industry to develop healthier products.

The Australian Government has also set up a National Collaboration on Trans Fats that includes representatives from the Australian National Heart Foundation, the Australian Food and Grocery Council, the Dietitians Association of Australia and FSANZ. The primary aim of this group is to work cooperatively in reducing the amount of trans fatty acids in the Australian food supply without an associated increase in the amount of saturated fat. The group will promote wide implementation of current industry and public health initiatives for reducing the levels of trans fatty acids and increasing consumer awareness and understanding. http://www.foodstandards.gov.au/newsroom/factsheets/factsheets2006/transfattyacids24oct3388.cfm

Q. I know that failsafe eating is meant to help with PMT, but my almost 15 year old daughter who has had monthly cramps but no period for 4 years suddenly got her period. We have been on the elimination diet for 3 weeks. Is this a coincidence?

A. As well as an improvement in PMT, failsafe women have reported reductions in period pain, postnatal depression and clots during menstrual bleeding. There have also been several reports of overcoming infertility - in other words, a pregnancy within months of starting failsafe after years of trying. So your daughter’s experience is possibly not a coincidence. We’d love to hear of any similar reports (email suedengate@ozemail.com.au).

Q. My daughter’s skin prick tests show a moderate allergy to cows milk and we have trialled soymilk several times but it makes her depressed, intrusive, argumentative and very negative (feels the whole world is against her). She seems totally unaware of this occurring, even when pointed out. Is this a reaction you are aware of? 

A. Some children do have behavioural reactions to soy milk. We would like to hear from anyone else who has experienced soy-related depression. (suedengate@ozemail.com.au)

Q. My 18yo son has been a failsafer for 8 years now and has always been excellent with his diet. We recently had a very upsetting time when over a period of months he deteriorated into an angry, swearing, depressed young man. The cause turned out to be that an avid gym goer, he was taking Musashi Protein food (powder) mixed with water, every single morning after going to the gym to build himself up and as an additional protein source. The ingredients included, amongst other things, a couple of flavour enhancers, although not numbered. Would full cream canned milk powder or Sustagen be an alternative for him to take? He says he needs to get the extra protein but obviously can’t cook himself up a meal as he goes straight to work from the gym so something he can mix with water like he did with the protein powder would be ideal.

A. If he can tolerate dairy foods, milk powder or Sustagen is okay. Pure egg white powder is another alternative you can sometimes find amongst body building supplies, it goes well in a milk or soyshake.

Q. Can you tell me what sort of cooking oil I should use to avoid macular degeneration (AMD)?

A. A recent review in the Medical Journal of Australia found that the evidence regarding dietary fats and AMD is conflicting regarding saturated, polyunsaturated or monounsaturated fats; that three out of nine studies found a diet rich in dark green or yellow vegetables helpful; that the only proven modifiable risk factor for AMD is smoking; and that a low fat healthy diet with vegetables is probably a good idea. See the full details at http://www.mja.com.au/public/issues/184_09_010506/guy11072_fm.html.

Q. Can pool chlorine affect children’s behaviour?

A. Yes! This is a common problem every summer when schools start the swimming programs, see story number [466], Swimming pool chlorine triggers oppositional defiance.

Q. We’ve been meaning to do a dairy challenge but there always seems to be a reason not to.

A. From the beginning of January and right through first term is usually an excellent time to do challenges because the party season is over.

Q. My oppositionally defiant amine-sensitive daughter is having a hard time at the moment and I am wondering if it might be due to spring flowers?

A. It is well known that salicylate responders can be affected by the scent of flowers and plant products such as bark, potpourri, essential oils and incense and a salicylate-sensitive failsafer from New Zealand has commented that Australian natives seem to be particularly strong. What about amines? We would welcome feedback from amine responders on this topic (suedengate@ozemail.com.au).

Q. My daughter has had severe reactions to cochineal pink colour (120) in a strawberry milkshake and some sweets. The reaction seems to occur within minutes and presents as a significant rash from the part way up the nose across the face to the jaw line. She gets significant swelling, although no breathing symptoms. Why is this not in your banned list?

A. Reactions to cochineal (120) are true allergic reactions to proteins in the cochineal which is made from crushed beetles. As such, they are quick and easy to identify - which is what you have found. The treatment for true allergies like this is avoidance of the allergen. Allergy to cochineal is quite rare whereas the additives on our banned list cause a very wide range of intolerance reactions in large numbers of consumers. Unlike allergies, intolerance reactions are usually delayed and can be difficult to identify except through the use of an elimination diet.  (Further reading: Chung K and others, Identification of carmine allergens among three carmine allergy patients. Allergy. 2001 Jan;56(1):73-7, abstract on www.pubmed.com)

(August 2006)

Q: I see there have been food recalls and publicity in UK about the carcinogen Sudan 1 in artificial colour Sunset Yellow 110 and in some foods. What's happening in Australia?

A: If a change is made in international specifications for an additive, which usually takes years through a committee known as JECFA, then the new specification will be picked up when the Australia and New Zealand Food Standards Code is amended and updated.. For instance, the permitted level of lead in sunset yellow (110) has just been reduced from 10 to 2 mg/kg. Not that any of us are eating such stuff.

Q: I have found a commercial bread, at a good price, made of unbleached flour but it contains 282. The ones I can find without 282 contain bleached flour. What is your opinion - which is worse ?

A: 282 is worse. The Bread Research Institute in Sydney confirmed that there is no bleached flour produced or sold in Australia, nor is there permission for it. The only exception is in commercial sponge flour, which you can't buy as a flour at the retail level. If you buy a cooked sponge cake there is a small chance that the flour will have been bleached to stabilise the protein so the sponge doesn't collapse. A lot of the claims on websites for bleaching of flour relate to US flours, which are made from red wheats which may be bleached to give a whiter appearance.

Q. For at least 2 years now I have constantly suffered from reflux and could never work out what was the common ingredient. After seeing the 635 TV segment I found that 635 was a common element in the foods in our cupboard. As an experiment I stopped eating foods that contained it and after two days the reflux disappeared. About three weeks later I suffered another bout of bad reflux and looked at what had changed. That night I had eaten some BBQ chips that contained, you guessed it, 635. Are there other people for whom 635 has had this effect?

A. Yes! People react differently to food chemicals so any food chemical can cause any reaction. While 635 is often associated with itchy rashes, it can also be associated with any other food intolerance symptoms including reflux and children’s behaviour. On our DVD, one woman talks about itchy rashes, swelling of the lips and tongue and extremely painful spasms of the oesophagus due to 635. “I thought I was going to die,“ she says. Although food regulators claim consumers are protected by food additive labelling, in our experience both consumers and their health care providers are usually unaware of the effects of food additives, resulting in years of unnecessary pain and medication. 

Q. Is it possible that fish oil could have caused an increase in my Aspergers son’s behaviour problems? It may purely coincidence but it appears that his behaviour seriously deteriorated when we started giving him the fish oil and it improved (or rather went back to what it was before the fish oil) a couple of days after we stopped giving it to him.

A. Fish oil is thought to benefit about 30 per cent of children with learning or behaviour problems. Others can be badly affected due to the presence of natural salicylates (in ingredients such as thyme oil, evening primrose oil and lemon or lime flavouring) and natural amines in fish oils. Failsafers have reported adverse reactions including behaviour problems, depression and migraines to a range of fish oil products. See below for reader reports regarding children's reactions. Some families do a fish oil challenge for a week or more while keeping a careful food and symptom dairy - at the end of the time, parents can review the diary and decide whether their child is better or worse.  For more details and reader reports regarding the fish oil’s claims to be salicylate and amine free, and some children's reactions, see the new factsheet: Fish oils, Vitamins and Vegetables.

Q. With depression etc at record highs, I’m just wondering if anyone has done a study on tartrazine (colour 102) and its effects on emotions, more specifically, depression.  I have been challenging things from my seven year old daughter’s diet. Yesterday we had some fruit mentos and afterwards she was teary, her eyes were purple and red and blotchy.  As for me I felt suddenly stressed and angry. This lasted about 1/2 hour for me and about 1 hour for her.

A. The link between food chemicals and depression is generally not recognized by the medical profession, and there is only a little research about it, see the Depression factsheet on our website and also the Sleep Disturbance factsheet. Most of the studies on food colours have concerned hyperactivity but food chemicals including artificial colours and salicylates can affect people in different ways. Some children may become hyperactive, loud or aggressive after exposure to artificial colours or salicylates while others may become quiet, inattentive, tearful or anxious. Effects of food chemicals can change with age, so that children who react with hyperactivity in primary school may react with depression in high school. If they are eating food chemicals that affect them all the time, the condition will appear to be chronic as reported in the Parker and Watkins 2003 paper described in the depression factsheet. This issue is so overlooked that medications for depression are coloured with artificial colours!

Q. My sister says I should take my kids to Advanced Allergy Elimination (AAE) to get them desensitized. Can you tell me if that works?

A. There is no scientific basis for AAE and it can be very expensive. Some people say it has helped them. Others say it hasn’t.

 Q. Is home brand OK for soy drink, wheat bix, rice bubbles and 2 minute noodles (the ingredients say wheat flour, vegetable oil (palm) water and salt?

A. Read the labels carefully. Some home brand products are OK but if you buy a product that contains any vegetable oil (that includes  2 minute noodles or soy drink), it probably contains unlisted antioxidants like BHA (320) in the vegetable oil. It is impossible for us to get accurate information about legally unlisted antioxidants in vegetable oils in homebrand products so we don’t recommend them.

Q. We have been through the RPA elimination diet but my three year old did not fit the mould.  She has major reactions to anything orange or yellow such as corn, pumpkin, apricots, citrus fruits, pineapple, egg, etc  Her reactions occur almost instantly at the slightest amount of any of the above – there is no build up.  It is enough to use the same spoon to serve peas as carrots to give her a reaction. 

A. I can’t find anything in the medical literature about allergy or intolerance to beta-carotene but you are not the first to report this problem. I would like to hear from anyone else who thinks they may have a sensitivity to this food chemical. (email confoodnet@ozemail.com.au)

Q. My son had a severe outbreak of hives while taking Robitussin ME for a cough. The doctor was surprised with the reaction to the Robitussin, but as soon as we discontinued using the product the hives went away.

A. This is the second report of severe reactions to Robitussin ME we have received, so it is worth reporting it - the Adverse Events Medications Hotline ceased to exist from June 2006, due to lack of funding but the Adverse Drug Reactions Advisory Committee can be contacted with reports of reactions. Although this is technically not their role, they are apparently very concerned about the situation and will take note of any reports. ADRAC phone 1800 044 114.

Q. I saw a dietician but she seemed quite vague about it and I got a lot more information from your site than she gave me anyway. I really need to see a good dietician so any recommendations would be appreciated.

A. We receive a lot of feedback like this. Our list of supportive dietitians is available on request from confoodnet@ozemail.com.au. If you are prepared to travel, ask for one of our miracle workers, a small group of dietitians who are very experienced and talented. If you see someone who is less than helpful, please give us the name so we can warn others. Dietitians in hospitals and community health centres are free, some are helpful, some are not. There are some good free dietitians on our list. To find a private dietitian, you can go to the dietitians’ website www.daa.asn.au, click on Find an APD, choose Allergy and Food Sensitivity (under Area of Practice), and your suburb or state as your search terms, then look for anyone near you - and let us know what you think of them! The best way to judge a dietitian is to ask them how many years experience they have in supervising the RPA elimination diet.

(May 2006)

Q. I am wondering if you can tell me what food groups aggravate arthritis as my father is suffering from arthritis in his feet. He has already noticed that when he eats tomatoes and also dark chocolate, his feet are a lot worse for the next few days.

A. Salicylates, amines, additives, dairy and wheat – any or all can affect arthritics. Suspect salicylates first. Tomatoes contain both salicylates and amines, chocolate contains only amines, so it could be both affecting him or only amines – also in cheese, wine, tinned or frozen fish, broccoli, tomatoes, bananas, mushrooms and many others.

Q. I have read your books, which have been terrific! I have applied your facts to my own children and I am forever getting credit for their good behaviour, many thanks to you!! I was wondering if you have yet got a DVD out.  I know a lot of friends that would take the time to watch a DVD rather than sit and read a book!

A. Thanks for asking - yes we have, it was released on 1 May 2006, see some very positive reader comments in One Liners. Details on www.fedup.com.au

 (our new easy to spell website name).

Q. I was also wondering if you are going to do a talk in Ballina or  Lismore soon?

A. No, after Grafton and Coffs Harbour I won't be doing any more talks until next year - I have to stop talking and start writing to get my books back on the shelves. But you can buy the DVD through the website, it is better than the talks in my opinion.

Q. Since we have been buying bread without preservative 282, we have seen a huge difference in our 6 year old son (we have also been avoiding other preservatives).  However, up until now, we have only bought Brumby's. Two weeks ago, I noticed that Wonder White was now free of preservatives. Two weeks on and two weeks of absolutely nightmarish behaviour has forced me to change back to Brumbys. Our son has not had Wonder White for three days now, and everything has really calmed down again. What are your thoughts?  Other than this bread, there has been no other change to his diet that I believe could explain this. When we switched to preservative free bread last year, within a week my son's behaviour had changed so much we were astounded. The last two weeks felt like we were back where we started  - but it took that long to realise what it was! ...

A. Most supermarket breads that advertise “free of artificial preservatives” use vinegar as a preservative instead. Many children whose behaviour is affected by additives are also affected by natural food chemicals called salicylates and amines, and vinegar contains high amounts of these, so you are better off sticking to Brumbys or Bakers Delight breads, or looking for breads with no preservatives, vinegar, antioxidant 320 or whey powder (that’s another source of problems in bread). You would probably find your son would improve even more on a trial of the low chemical elimination diet (free of additives, low in salicylates, amines and flavour enhancers).

Q. I’m trying to track the cause of a persistent skin rash in my 2 year old son. Are Brumbys’ sausage rolls OK?

A. No! We recommend ONLY the plain breads and the white iced finger buns at Brumbys – nothing else. Beware: the plain white iced cup cakes that look failsafe are preservative free, but contain sunset yellow (110) artificial colour. And the sausage rolls are a disaster area. In North Queensland, sausage rolls sold in Brumbys contain 8 nasty additives: artificial colours 102 and 124, annatto colour160b, potassium sorbate 202, sodium metabisulphite 223, synthetic antioxidant BHT 321, flavour enhancers 621 and 631. For skin rashes I would suspect 631 first (a nucleotide flavour enhancer, see Ribo Rash factsheet), but any of these could cause a skin rash – or behaviour problems, or asthma.

Q. When my son was getting ready to go failsafe, he ate sausages one time and hot chips another and reacted to both hours later with exercise induced asthma. Do these foods have an additive in common?

A. Sausages and hot chips are classic sources of sulphite preservatives (220-228), the additive most likely to be associated with asthma. See Papazian article for an FDA article about sulphites in French fries, describing a quick, obvious reaction. It is less well understood that sulphites can cause irritated airways with no obvious symptoms until combined with exposure to an environmental trigger such as exercise – and it can happen hours or even days later. Further reading: Sulfites: Safe for Most, Dangerous for Some by Ruth Papazian (do a google search for free full text), and see the full story in Reader Stories. The child in the question went on to win his school cross country race while failsafe with ‘no asthmatic reactions at all afterwards or during, whilst plenty of kids were, in his words, "dropping like flies with asthma attacks all around him" - some quite seriously so! Of course, as usual, the school had a sausage sizzle going all that day to raise money - bizarre isn't it?’ 

Q. Is there any research on nitrates entering the food chain through water? I have noticed in intensive farming areas of northern France that they no longer drink the local water because one will become violently ill after three days. This is due to the high nitrate input when producing maize in the area. I have also noticed in the same area that the incidence of teenage problems from suicide to poor exam results to excessive drink and drug problems are a major puzzle for the adults. This is an area where they do not agreed with fizzy drinks or sweets and bake their own bread.

A. Contamination of ground water by nitrates from agricultural fertilizers is a common, well documented and increasing problem. Nitrates are transformed into nitrites in the GI tract and can be fatal to infants when the water is used to make up baby formulas. There are also concerns about cancer risks but there has been very little research concerning other health risks and none regarding behavioural effects on children. Yet another reason to drink filtered or bottled water. Further reading: Kumar S and others, Need for revision of nitrates standards for drinking water: a case study of Rajasthan. Indian J Environ Health. 2002;44(2):168-72; Kozliuk AS and others, Immunologic status of children living in a region with an increased level of nitrates in the drinking water, Gig Sanit.1989 ;(3):19-22.

Q. I was wondering if the product from Healtheries Kids Care Rice Wheels are failsafe - in the ingredients list it includes something stated as Barbecue flavour (natural and nature identical flavouring substances). I wondered if this was an attempt to hide anything sinister.

A. As journalist Eric Schlosser says in his book Fast Food Nation, ‘Natural and artificial flavours are now manufactured at the same chemical plants …calling any of these flavours “natural” requires a flexible attitude’. The ingredients in added flavours don’t have to be listed because they are trade secrets. Under the 5% labeling loophole, flavours can contain unlisted artificial colours and preservatives, so I suppose the word ’natural’ protects you from those but you can work out what barbecue flavour might contain from a barbecue sauce recipe: tomato soup, tomato sauce, molasses, vinegar, onion, seasoned salt, mustard, Worcestershire sauce, orange or lemon zest, paprika, pepper. So it doesn't matter whether it's natural or artificial - it's NOT failsafe.

Q. Is there anywhere to get soft canned pears? Lately they’ve been like rocks.

A. In my experience, it is always worth complaining - politely at first - about a specific product to the manufacturer, telling them exactly what is wrong and giving them the product code, useby date etc. I wrote to Great Lakes complaining about their hard pears (greatlakes@maxwellfoods.com) and quoting the all the numbers on the bottom of the can. I received a very friendly letter explaining that they have been using a snow pear variety that is crunchier than the traditional Bartlett variety but they won’t do it again, and sending a $5 cheque for the inconvenience.

Q. Just wondering if you can tell me what foods are most likely to affect speech especially stuttering?

A. It depends on the child. For some children, the answer can be avoidance of one or two additives such as nitrates in ham, benzoates in drinks or the bread preservative. Other children may need to do the full elimination diet. See our new factsheet on stuttering and other speech anomalies, including speech delay, loud voice, vocal tics and silly noises.

Q. I believe that my niece has mild autism that is food related, I've talked to her parents but as they say you can lead a horse to water but you can't make it drink.

A. The easiest dietary changes you can recommend are to switch to a2 milk (see www.a2australia.com.au); preservative free bread from Brumbys or Bakers Delight; drink water instead of juice and cordial; and avoid artificial colours in lollies by switching to Werthers Originals. Some children improve so much just by doing this that families are then prepared to try the full diet.

Q. I saw Velcorin listed on a fruit juice label. Is it a safe additive?

A. Velcorin is a new antimicrobial agent chemically known as Dimethyl dicarbonate (DMDC). It is used for the cold sterilisation of non-alcoholic beverages and can reduce the need for nasty preservatives such as sodium benzoate (211) or sodium metabisulphite (223). Once added to the product, Velcorin breaks down quickly into small amounts of carbon dioxide and methanol, which occur naturally in most beverages, including fruit juice. It is too early for us to be sure, but it seems highly likely that Velcorin will NOT cause children’s behaviour, learning problems and other symptoms of food intolerance. (Failsafers will still have to consider natural salicylates and amines in the juice itself). More information about natural food additives including natural colours from www.victus.com.au

Q. Are Ingham’sLite Chicken Breast Nuggets’ failsafe?  Ingredients: Chicken (Minimum 56%), Flour (Wheat, Maize, Rice), Salt, Water, Wheat Starch, Whey Protein Concentrate, Thickener (1400), Vegetable Oil, Vegetable Gum (412), Sugar, Mineral Salts (451), Bakers Yeast, Ground Spice. (97% fat free, no artificial colours, flavours or preservatives, cost $6.69 for 13 nuggets at Coles)

A. Although the label says ‘no colours, flavours or preservatives’ there could be unlisted BHA 320 or TBHQ 319 in the vegetable oil, the ground spices are a source of salicylates, and as far as we can work out the Bakers Yeast in a non-bread product is probably there as a natural source of nucleotide flavour enhancers otherwise known as 635.  Not recommended, see our recipe for homemade nuggets below.
