I suffer from depression.
recently I started using soya milk ( as I have become vegan) over the last couple of weeks I have been severely depressed, I havent felt as low as I have in a long time.
Well I was reading this book of mine about foods that effect your mood and one of the top five bad mood foods listed was soya!
So i did some more reasearch and found that Soy can cause depression
Now I dont know how much of this is true - I like to keep an open mind about wht I read on the net but I decided to stop the soy and funnily enough I have felt so much better.
Maybe it is coinsdence!

I am not sure.
Cos I have also read about the benifits of soy!
