I stated a little earlier on this thread that I was a vegetarian for several years, an earnest one, and I felt tired and fuzzy-headed all the time. Also, I am healing from drug damage done to me by an antidepressant, as well as chelating mercury from amalgam removal. My naturopath says that in her experience, people recover from these kinds of illnesses more quickly and thoroughly if they eat meat. I've learned enough about how my body reacts to certain things to know that this is true for me. I am on the Paleolithic Diet and would not eat legumes, grains, and certainly not soya, so where else would I get the protein I need? I'd love not to have to buy meat, it is expensive, but I've spent enough time being ill, I'm going to do what it takes to get well. I'm just not willing to sacrifice my health for a principle (i.e. not eating meat because there are too many people in the world who eat it)when it would not make a dent in the bigger picture anyway.
