While there are benefits to eating vegetarian, some blood types aren't able to handle it. I'm a type O, and when I ate raw vegan for 3 weeks I lost 6 lbs. and couldn't stand up without getting dizzy. I need red meat.
That being said, there are
a lot of health benefits to eating grass-fed meats...the way they are naturally meant to be eaten.
A couple of years ago I was diagnosed with Crohn's disease, and was told that fats and grains (especially wheat) should be avoided altogether. While large amounts of these items are very tough for me to digest, small amounts whole wheat and grass-fed meats go down just fine, and help keep my weight up. Same for dairy - goat is very easy to digest.
One of my favorite things to do right now is freeze some grass-fed beef in small patties (which kills the bacteria) and then cook it medium-rare and eat it with some leafy green veggies. Tastes great and is super-easy to digest.
Rick is right about the American food industry - we're in a time warp when it comes to food processing:
