GRAS is an acronym for the phrase Generally Recognized As Safe. This list is presented by the US Food and Drug Administration (FDA) and explains if a particular food or food additive has been shown by experts to be safe for use. This list a complex way of answering the question, “Is this food safe to eat?” If it is, the product should be listed. In 2018, the FDA removed partially-hydrogenated oils from the GRAS list, and as a result PHOs have been recently removed from the diet of Americans across the board after years of health debates.
