Oh I love meat, not eating meat to me is stupid. You need the minerals and vitamins from both meat and plants. But people eat too much meat, and even 1-2 meatless meals a week is great for you. People need a variety of foods.
I've been a vegetarian for 20 years and I am healthier than I used to be before. So your argument about what I "need" to eat is... a missed shot at best.
I DO eat variety of foods. But meat doesn't belong to that, that's all.
AND... I think even a child knows that the best source for vitamins are vegetables and fruits, not meat
