Autism and Diet

I've seen in the news lately that autism rates among children are sharply increasing.  A recent federal study estimates that now roughly 1 in every 150 children is autistic.  So what's causing all this?

Some researchers believe that gluten and casein in modern diets are to blame.  But a new study suggests that a lack of omega-3 fatty acids may be a large part of the problem.  This new randomized, double-blind study showed that supplementation with omega-3 fatty acids significantly reduced symptoms in autistic children. 

I hope that additional studies on this continue and that this information becomes more available to the public.  Many modern conditions can at least be partially treated by reverting to a Paleolithic diet.  In my opinion, this should usually be the first line of treatment before more drastic measures are taken.
