Speakers at AutismOne promote all sorts of diets to “cure” autism without any evidence to back it up. They have collections of testimonials , which do not collectively make evidence. While anecdotes may lead to hypotheses for further study, they are not, on their own, evidence. Put somewhat cheekily: the plural of anecdote is not data.
The entire claim that dietary inventions can “cure” autism completely depends on the idea that autism is curable, which, as we have discussed on this site, contradicts what we know about the genetics and neuroscience of autism.
