promoted by Dr. Benjamin Feingold
in the 1974
book Why Your Child Is Hyperactive
. The basic idea is that was used to be diagnosed as hyperactivity
and now is known by Attention Deficit Hyperactivity Disorder
is caused in many cases by children
eating too many artificial colors
and artificial flavors
or foods rich in natural salicylates
. Removing these substances from a child's diet can cause dramatic improvement in hyperactivity symptoms according to Dr. Feingold.
Of course, there are those who believe this is hogwash, and that the only treatment for hyperactivity is to dope your kid up on Ritalin, but it seems to me the Feingold Diet is worth trying as a first step, and is probably a better way to eat in general. I have known children who the Feingold Diet has at least helped with, and although they may still be using Ritalin their symptoms are much less severe overall.
