[QUOTE="Nelson Vergel, post: 17385, member: 3"] Another interesting one that shows vegans have higher SHBG than omnivores. Another study showing that removing fat and animal protein may not be best for men's sex hormone binding globulin. [B]Testosterone, sex hormone-binding globulin, calculated free testosterone, and oestradiol in male vegans and omnivores [/B]British Journal of Nutrition / Volume 64 / Issue 01 / July 1990, pp 111-119 Timothy J.
