Today we’re going to take a collective look at all the conflicting warnings and exhortations we hear about what we should and shouldn’t eat. It seems everyone has some pet theory that you shouldn’t drink milk, or you have to eat organic, or you shouldn’t eat "processed" foods, or you must only eat raw. There are always explanations for why this is: We didn’t "evolve" to eat this or that; it isn’t "natural" to eat something; our digestive systems weren’t meant to handle a certain thing. I know what you’re thinking: How is it possible to cover all those possible claims in a single Skeptoid episode? We’re going to do it by stepping back from all of the specific claims and specific foods, way back. We’re going to look at food as a whole, and study what it’s made of, what those bits are, see what we need and what we don’t. And then, with this as a foundation, we’ll have the tools to effectively examine any given eating philosophy.
