Vegetarian, Vegan and Animal Rights

But turn it around, and assume that all of us are naturally lactose intolerant--meaning that we are not meant to consume cow's milk, really, and that our eating it is an adaptation for survival in cold climates back in history. Not our natural food, in other words. We get used to it, but we do better without it. And when we eat some once in a while after not having it, we notice the effects.

Same thing with meat--a meal heavy with meat will make a person feel sluggish and slow, compared to a plant-based meal. But when people have it every day, three times a day, they think how they feel is normal. They don't know how good they could be feeling.
