My story started with an uncontrollable daughter who at 8 years of age was already getting suspended from school and was a horrible bully. The school wrote me a referral to a paediatrician. At the time I thought would only mean having her medicated to control her which I was dead set against.

I have two older boys that were very well behaved so I wanted to find the cause of the problem and not just cover it up with medication. Three days after Christmas 2002 my daughter went off to such a degree that all I could do was hold on to her while she bit, kicked and screamed until she was physically exhausted. That was when I knew there was something seriously wrong so I went to see a child psychologist who fortunately for me recommended your book Fed Up.

Within a month I went from thinking my daughter was destined for jail to thinking what a lovely young girl she is turning into. The results were noticeable that quickly. And from my daughter’s point of view she felt better within herself. She was no longer on an emotional roller coaster every day. Because of how she felt on the diet it made it easy to keep her on it. She was feeling a whole lot more in control of herself.

Since cleaning out our cupboards I noticed that my eldest boy no longer suffered migraines and no longer took so long with gut aches on the toilet. So obviously he also was affected by these chemicals but in a different manner than my uncontrollable daughter.

Now in our family two of my nephews and a niece have also gone on the diet with the same excellent results. One of my nephews went from struggling to get through one reader a week to reading one a night almost instantly.

My daughter is now twelve with her full potential being realised and is the biggest advocate of all for the failsafe diet. We laugh now about what we refer to as her "psychotic episodes" (which thankfully we haven't seen in a few years now). I used to think "what did I do so wrong with my daughter. My boys are good boys where did I go wrong." It was good to learn that it wasn't anything I did wrong as such. It was the food I was feeding her. – email, NT
