Dutch scientists have found that children with ADHD might be able to alleviate symptoms by changing their diets. One hundred young children were put on two diets—one group ate whole, hypoallergenic foods such as rice and vegetables, while the other ate a normal diet including processed foods. At the end of five weeks, 78 percent of the children on the non-processed, hypoallergenic diet saw a decline in ADHD symptoms. While the link between ADHD and diet is known, the study is the first large, long-term look at the relationship. ADHD affects eight to 10 percent of the school age population in the US.
