Health notes

Lactose is generally recognized as safe (GRAS) by the FDA. Many individuals, especially adults, experience lactose intolerance because their bodies do not produce enough of the enzyme lactase to digest it. This can lead to digestive discomfort. JECFA has not set an acceptable daily intake (ADI) for lactose, as it is a natural component of milk rather than a food additive.
