And it has nothing to do with animal rights!! It's just a healthier way to eat.
All of my vegan friends look like death warmed over and they catch every ailment that comes down the pike.
I've know all of them since the 60's but they really started going downhill when they became vegetarians and it happened quite rapidly. I was one of them but quickly saw that the vegetarian way was not really "healthy" like its advocates claimed, but was actually quite the opposite.
Went back to moderate amounts of meat in my diet (my appetite usually guides me correctly...that's what it's there for) and have maintained tha same weight within 3 pounds and the same healthy blood pressure for over 20 years.
I still eat a lot of veggies, but I don't don't treat meat like it's the worst thing that ever happened.
