Don't consume tofu as its very controversial food. Studies have shown that it lowers testosterone levels in males. Also, Soy beans are naturally toxic to humans, but they're harmless when they go through a fermentation process, which is how we get tofu.
But soy is being used in more and more things these days. Just look through your cabinet. You'll be surprised.
Anyway, most companies aren't putting their soy beans through this process because it takes too much time, and time = money.
Instead, they put it through a chemical process, but this rarely gets rid of the soy's toxicity completely.
Symptoms of a high soy diet are thyroid problems, breast cancer, and other complications.
People get these symptoms because the soy they eat isn't fermented.
