Re: Autism spectrum disorder: advances in diagnosis and evaluation

I am grateful to Joel Brind, but while I would not wish to dismiss out of hand low glycine consumption as a potential factor in autism - among other environmental influences - I also note that his statement:

"There has been in recent years, in the industrialized world, a general dietary shift away from the consumption of whole meats, fish and poultry, toward the consumption of exclusively muscle meats."

is not supported by any cited evidence, though he has twelve footnotes. Meanwhile, I still find on visits to supermarkets that the shelves are still stacked with fish and poultry as well as "muscle meat". I understand that even Macdonald's offer alternatives to burgers, including fish and chicken. Nor, perhaps, would the parents of autistic children like to be stereo-typed as burger eaters!
