In the 1980s, the United States Food and Drug Administration (FDA) made a sharp delineation between food and medicine. Food products were not allowed to claim to have medical benefits, and so-called health foods were considered to have "no legal definition."
至於美國，八○年代食品與藥物管理局 FDA 把食品與藥品做二分，不准食品宣稱療效，認為所謂的健康食品是「無法定義的」。
