"If there’s one thing I know for sure, it’s that carbs are evil. This is probably the silliest of all the silly, pop-culture propaganda about diet and health."

"All plant foods are carbohydrate sources. Yeah, but: Carbs are evil. Everything from lentils to lollipops, pinto beans to jelly beans, tree nuts to doughnuts, is a carbohydrate source. Most plant foods are mostly carbohydrate. So if 'all carbs' are evil, then so are vegetables, fruits, whole grains, beans, lentils, nuts, and seeds. Sure, but, I should still avoid carbs, right? Exactly the opposite is true. You cannot have a complete or healthful diet without carbohydrate sources. Why have I been led to believe that carbs are evil? Highly processed grains and added sugar are bad, not because they are carbohydrate, but because they’ve been robbed of nutrients, they raise insulin levels, and they’re often high in added fats, sodium, and weird ingredients. Carbs are not evil; junk food is evil."
