Definition: Legally, food labeled "natural" does not contain any artificial ingredients, coloring ingredients, or chemical preservatives, and, in the case of meat and poultry, is minimally processed.
Meat from animals treated with artificial hormones can (and is) labeled "natural," as is meat injected with saline solution (claimed to add flavor, which it does, but it also adds considerable weight to a product sold by the pound). Food containing "natural flavors" such as processed proteins that you may or may not consider desirable can legally sport the label "natural."
