A list of food additives/ingredients considered to be Generally Recognized as Safe, by the American Government’s Food and Drug Administration (FDA). This list of additives is judged to be safe by a panel of FDA pharmacologists and toxicologists, who base their judgment upon data that is available for each ingredient. In practice, those additives for which extensive experience of common use in foods (without known ill effects) has been accumulated over time (e.g., common table salt) are often approved by the FDA due more to the “common use factor” than to any toxicology data, per se.
