Our bodies are so complicated that it's difficult to determine what exactly is good for them and what is not. So much effort goes into trying to figure this out, but many different results are often obtained. Since we're all different, this makes sense to some extent. I think that as long as we keep biology in mind and remember that we evolved to survive and thrive in a natural enviorment, we can make smart food choices. That is, foods that were available to us millions of years ago, like fruit or nuts, are generally good for us, whereas things we've recently concoted such as Twinkies and Oreos generally aren't. Even supplements should be viewed with a skeptical eye. Our ancestors survived without them, so we shold be able to make it as well.

No matter how much we try to defy nature, we cannot. Death, unfortunately, is inevitable, even if we want to optimize our nutrition to the fullest. We might as well be reasonable about it so that we can live life without spending every moment worrying if what we are eating is okay.
