Two of the components often used heavily in the vegan community scare me: flax and soy. I may have a bit of each from time to time but I do NOT want to make either a food group. The estrogenic part of it does not appeal. And I’m not convinced that there may not be negative consequences that go pretty far into the health of a person eating them heavily that may take quite a while to show up. I’ve seen things in my long term vegetarian friends that cause me to question whether they’re really even as healthy as their non-vegetarian brothers & sisters, things like heart troubles, gall stones, strokes, diabetes, cancer, and Alzheimer’s, not minor things.
I don’t know about anybody else, but 46g of protein, for me, is a protein deficiency.
