Soy is an important protein source for vegetarians and vegans and can safely be consumed on a daily basis along with a variety of other plant protein sources. It’s important to note that research points to the benefit of consuming soy when in it’s least processed forms (tofu, tempeh, soy beans, soy milks, and edamame). Benefits include reduced risk for cancer, heart disease, type 2 diabetes and hot flashes. Remember, it’s not just a single food that typically causes harm. You have to also take into account the whole scope of your eating patterns because we don’t eat foods in isolation.
