Can people with lactose intolerance consume protein powder?
Lactose intolerance generally does not prevent someone from consuming protein powder, provided the protein powder is lactose-free and the individual is not allergic to the protein.
Lactose intolerance usually refers to reduced activity of lactase enzyme in the body. After consuming foods containing lactose, the intestinal mucosa may become irritated, easily triggering diarrhea. Protein powders are rich in protein, and moderate consumption can effectively supplement the body's protein needs. However, it's important to check the ingredient list when consuming protein powder. If it contains lactose, it should be avoided, as it may otherwise lead to symptoms such as bloating and diarrhea. Additionally, because individuals vary in constitution, those who are allergic to a specific type of protein should not consume it, as doing so may trigger allergic reactions.
Lactose intolerance is most commonly seen in infants and young children. Once diagnosed, it's best to avoid protein powders and formula milks that contain lactose to prevent discomfort and adverse symptoms.
