Actually, this is not established at all.  It's an "obvious" observation
on someone's part.

Autistic people tend to have brains and heads considerably larger than
those of the general population.  And they have their own special types
of attentional problems.  Those who are high functioning are often
diagnosed ADD.

I'm not prepared to argue the importance of diet here, except that there
is some amount of connection between problems with grain eating and the
condition of autism.  That is, celiac disease (gluten intolerance of
some type) tends to be higher in the autistic population than in most
other groups.
