This post summarises a couple of things I stumbled upon. While browsing Wikipedia, the page on peptides actually contains this:

It has also been documented that, when certain food proteins such as gluten, casein, egg protein and spinach protein are broken down, opioid peptides are formed. These peptides mimic the effects of morphine, and those who are unable to break them down will experience mental illness. These peptides are quite short and are given names such as casomorphine, gluten exorphine and dermorphine.

What proof have they got for that? peptides are basically like proteins, but simpler. It's not alltogether clear where one category starts and the other ends.

Science Blog speculates that obesity may be contagious, via a virus.

Same guy behind that obesity stuff though. More sources needed.

Lastly I read a claim on Slashdot (How's that for trusted sources :-) that 90% of autists are of blood type A. Sources needed!
