I started supplementing with soy protein powder over a week ago and think it is the cause for my severe stomach cramps and bloat. I actually switched brands to see if that was the problem, but still no luck. I'm really upset about it since I like it very much.
My husband, who is not a big fan of soy, sent me the following article: http://www.utne.com/2007-07-01/Scie...f-Soy.aspx
The women there writes "After years of consuming various forms of soy nearly every day, I felt reasonably fit, but somewhere along the line I'd stopped menstruating. I couldn't figure out why my stomach became so upset after I ate edamame or why I was often moody and bloated. It didn't occur to me at the time to question soy, heart protector and miracle food."
I too lost my period a while ago having been a big soy milk drinker but never was sick or bloated. But now I am, due to the potein powder, I believe.
I just wondered if anyone else has any experiences like this or any thoughts on the matter.
