which gives you a 12 page document. This is from page 4:

"The peak years for annual con-
sumption of HFCS coincided with the peak growth rates
of ASD in California, the only state that reports number
of cases of ASD dating back to the mid-1980s [4]. The
Mercury Toxicity Model shows the HFCS characteristics
most likely contributing to autism include the zinc-
depleting effect that comes from consuming HFCS and
certain food colors found in processed foods, and the
additional Hg exposure that may occur from the low Hg
concentrations sometimes found in HFCS as a result of
the manufacturing process [4,17]. This model can be
expanded to include additional adverse effects associated
with the consumption of HFCS that likely contribute to
the development of autism through PON1 gene modula-
tion and lead intoxication."

Its a complex argument I haven't gone through myself. The graph I attached was just one that had the most up to date numbers showing the levelling-off to stable trend for HFCS consumption. It just happened to include a line for autism frequency.
