Finally, in addition to all the other reasons to eat fruits and vegetables, there are some that relate to the brain. The pigments that account for the varied colors of vegetables and fruits have antioxidant properties that offer significant protection against cancer and other chronic diseases, as well as protection from a range of environmental toxins, including pesticides. Toxic injury to the brain is almost certainly the cause of Parkinson's disease, and probably amyotrophic lateral sclerosis (Lou Gehrig's disease). For that reason alone, it's a good idea to eat every day from as many parts...
