If dairy is not good for mercury detox, then a vegetarian is going to have to go vegan. It's very hard as a vegan to make sure that enough protein is consumed, at least on a low carb diet.

Maybe this is the problem, not the meat itself - the need for a high protein diet, low carb diet. From what Russ etc have said, I'm suspecting that is the key - to go low carb. Eating meat and vegetables is essentially the low carb diet. This helps with diabetes and other health problems.

It's very hard to be low carb, high protein on a vegan diet. I'm going to try going vegan again, but am looking for a good protein shake to take. There are a lot of shakes out there, but unfortunately are not all good.
