Seems like a lot of people believe that eating/using natural products are healthy. Commercials/ads abuse this a lot too.
But really though... cooking is rather unnatural. Only humans do this. And they do so in all cultures. Even so, it's hardly natural.
Same goes for drinking milk after your mother stops giving milk. That's pretty much nature's decision. When the mother stops giving milk, the young ones will have to do without milk. There's lots of other things.
So when you put it all in perspective... Cooking, drinking milk, clothes, etc... while not natural, are good for your health. Of course, this is just living in a natural way... the way nature seems to have intended it. Humans have evolved in such a way, that they can make most products in nature healthy to them.
What are your thoughts about this?
