There is an ongoing debate over the relation between wheat/gluten and sugar allergies in an autistic child. Usually, children on the autistic spectrum seem to react very strongly to sugar, in general, and sugar replacements like high fructose corn syrup, in particular.
From a personal point of view, I came to realize that I am allergic to wheat/gluten by following an elimination diet meant for my daughter: I became her buddy after several failed attempts at keeping her off wheat/gluten. We both felt better within days of starting the diet: more energy, happier mood and less foggy brain. The most amazing change was the disappearance of my six-year-old eczema. It just went away. No shots or cream. Every time I get exposed to gluten, the eczema comes back with a vengeance!
Then, I got the surprise of my life: migraine headaches after drinking soda fountain. I could not make any connections between my gluten and dairy allergies and the horrible headache produced by drinking soda.
I did the only think I can think of: more homework. Several days later, I found an old book published by Reader’s Digest in 1982. It is called: Eat Better, Live Better. In the last chapter, the authors mention the existence of related food allergies. According to this article, a “person allergic to one food in the family is likely to be allergic to some or all of the other foods in that group”. Also, the “grass” food family includes wheat and bamboo shoots (used to produce cane sugar). This might be the proof for the connection between sugar and gluten intolerance in susceptible individuals.
For my part, I stopped drinking soda for two reasons: it contains high fructose corn syrup which gives me a horrible headache and the lining of all bags from soda fountains are made from a wheat derivative!
Imagine that: there is wheat in the lining of the bags containing soda!
