Some of you are probably aware of Bill Walsh Phd. as a student of Pfeiffer (who was an early pioneer in the brain/ nutrition research).Walsh has a book out called Nutrient Power and is an excellent read as an adjunct to the info available on this site. He details the epigenetic influence on many of the afflictions we as a nation suffer from. I personally believe that autism and other ASD are treatable and Walsh in his work details the mechanisms that drive the disorders. It seems I am hawking books today but I believe in giving back to this forum--it has improved my life through the info on methylation.
