My 6 and a half year old daughter has been diagnosed with PDD-NOS. Since about 6 months of age, we have given her those kids yoghurts that you buy in 6 packs with the kids themes like Nemo and Bob the builder. We thought that because she wouldn’t drink milk we needed to give her a dairy substitute, and that they would suffice.

While being a generally placid child since birth, she displayed difficulty concentrating on tasks, a great attraction to the colour yellow, meltdowns at times such as leaving a friend’s house or upon being denied a request, sneaky poos, bedwetting, and poor fine motor skills. She was assessed as having a severe speech delay when 3 and a half. Her drawing was at best scribbling in a general area, and she had great problems following dotted outlines of alphabet letters. She displayed very poor short term memory, and repetitive behaviours. She was also wanting food all the time, although she is not overweight. She only drinks water, has never eaten confectionery, has ice cream on the odd occasion, but otherwise generally eats rice bubbles, weetbix, watermelon, grapes, apples, pears, occasionally custard, and plain biscuits. Dinner is usually either rice, pasta or mashed potato with steamed veggies and fish, chicken or beef with no added sauces.

Recently we were made aware of your book and in particular, the adverse effects of the 160b colouring additive. Upon reading up about it in the book, we also looked at the fed up website where we noticed the link to PDD-NOS. After reading some of the testimonials and realising that many of the other parent’s experiences were sounding familiar, we decided to eliminate 160b from her diet.

We initially stopped the kids’ yoghurts, which she had been having up to 5 a day, on 22 February 2009. Within about 4 or 5 days her drawing had improved remarkably, she could follow dotted lines correctly, her concentration to tasks jumped, not one meltdown occurred, her sneaky poos stopped, bedwetting reduced, and her speech started to improve noticeably. After noticing these improvements, we then looked at the rest of her diet and switched to Brumbys bread, eliminated anything else that we thought had 160b such as custard, switched to A2 or Jersey mik, and stopped using fabric conditioner. We have noticed over the last month that she seems to have matured noticeably, is more compliant, and is more focussed on cognitive tasks. Her teachers and tutors have all noticed a dramatic improvement in her learning ability. She no longer seeks food constantly, has lost her attraction to the colour yellow, has mostly stopped her repetitive behaviour, and her short term memory is markedly better. In fairness, we also started a reward scheme to help stop the sneaky poos at about the same time. However, she is a bit unique in that except for the 160b element, she was virtually following a failsafe style diet already. So we have been quite surprised that it seems that removing 160b has had a dramatic effect for her. -Sharon, Qld
