"Currently, the USDA’s National Nutrient Database, which is widely used as the “official” source for nutrient levels, includes more than 6,600 food products, including meat; fresh, frozen and canned produce; and processed foods. They even include candy bars, gumdrops, TV dinners and hundreds of fast food items in the database. But the agency has not included a single organic item, nor any entries for products from pasture-based meat or dairy systems."
