Things that Raise/Homocysteien

I just ran across another study showing that comething in coffee and tea raise homocysteine (translate dysregulate your methylation: http://www.ajcn.org/content/73/3/532.short

I thought I would invite comment. On a former memory stick that was stolen I had gathered some studies on coffee and tea regarding methylation and it seemed to show that coffee raises homocysteine but tea (overall) decreases it, although when tested by component, there are component(s) in tea that raise it.
However I found studies that showed tea causes neural tube defects in pregnant woman and that showed the reason it is stronger than any chemo on the market is because it breaks folate metabolism (something I do not want). I used to drink a lot of tea and stopped for this very reason. Tea has me puzzled because so many healthy people drink it and tout its health benefits.

On WrongDiagnosis a list of things that affect methylation was posted. I thought I'd repost here and see if anyone has any more to add.

These food items could be a reason for crashes and the like so it seems a good idea to keep them in mind:

Oh, I could not find that list so I guess I'll start a new one:
