Everyone is a fucking expert when it comes to diet. The body can take care of itself. It knows what it needs, if you listen to it. Just eat a variety of different foods, and pay attention to what agrees with you. Moderation is the key to everything in life, as the ancient Greeks wrote. Avoid fads, such as the vitamin fad, the vegan fad, the meatless fad, the all-meat fad, the raw vegie fad, the berries and twigs fad. Avoid processed, artificial foods -- cook your own food at home. See, I'm an expert on diet, too. Everybody is.
