I'm sorry you had such a difficult time on a vegetarian diet. I think everyone has find a diet that suits them and their needs. I say, there's nothing wrong with eating meat as long as you know where it's coming from. The best option
is supporting local farmers and choosing grass-fed or even organic meat.
Unfortunately, some people seem to have trouble absorbing iron. Even some meat eater are actually iron deficient. How are your iron levels these days?
