I wasn't insulted by what Meena wrote about me. I just have a personal rule about debating wackadoos.
I don't know that it is totally accurate to say that we are genetically omnivorous. There is a great deal of debate about that. It's not entirely certain what 'genetically herbivore' would even mean. Most herbivores will eat meat if they are hungry enough. And, it's very odd that we have to cook our meat for it to be safe and edible. We have to modify it. A big clue that you were genetically designed to eat a certain food is that you don't have to put it over a fire in order to keep from dying when you eat it. See what I mean?
Also, just about every single plague that has whiped out huge populations was a result of our consumption of meat. Every single one started in a different animal and jumped species. The vast majority jumped from our cattle to us. The current one is bird flu.
I also want to stress that a purely vegetarian diet is no more full of problems than any other diet. Getting everything your body needs without suplements is difficult and it's not something a lot of people do or try, even the meat eaters.
And there is a HUUUUUGE problem with including meat in your diet and not being careful about it:
Meat becomes very unhealthy if you eat too much. You get high blood pressure and cholesterol problems and heart attacks. Eating too many vegetables isn't going to kill you the way too much meat will. A diet with meat can be life threatening if done wrong. A vegetarian diet can possibly only lead to poor nutrition, but so can an omnivorous diet.
I pay close attention to my nutrition and getting what would otherwise have gotten from meat is the easy part.
