But I also wonder about the fruit and teeth since all fruitarians I've met had awfull teeth. But they tend to gorge on fruit, being starved for other nutrients. I always sip juice with a straw and rinse my mouth after most fruit. My teeth are very good and I've been on the diet for half a year. But that's still short, I know.
I really think, being happy and comfortable with a life rich in pleasures, as well as living and eating sustainably, in tune with your environment will make you most healthy. cheers to being unscientific.

If you're happy you will be more in tune with yourself and moderate because you are not using food for pleasure or punishment.
If I could choose, I wouldn't want to be a carnivore, like a tiger or lion. They seem edgy, moody,aggressive. Just not as nice as a rabbit or a coala bear. But I can be a bit sneaky and steal an egg or snatch a fish in a river and hit it over the head with a stone. But hell, I don't want to kill a cow!!!!!!!!!!!!!!!!!!!!!!!
