Tofu is low in fiber, though, even though whole soybeans boast 8 g per cup.  Soy foods contain isoflavones, natural chemicals that exert estrogen-like effects on the body. Some research suggests that isoflavones can raise cancer risk in women with a history of estrogen-related cancers and men with low-testosterone levels.
