I can't understand why we even care about any studies on rats. They only
prove what rats should/shouldn't eat. So what?
The same is true for any studies on animals. Feed rabbit or chicken with fat
and they get arteriosclerosis, it's no surprise to me.
It's like feeding men with grains and carrots. They will get sick
eventually, because it's not what he's supposed to eat.
