Adults can drink infant formula if they are not allergic to cow’s milk or goat’s milk. Infant formula mainly contains carbohydrates, proteins, vitamins, trace elements, etc. The above nutrients are the same as those needed by adults to maintain the functioning of the body, so adults occasionally drink infant formula will not affect their health, but because the energy and nutrients required by the adult body are higher than those required by infants, the nutrients in infant formula cannot meet the needs of the adult body. Therefore, adults can drink a small amount of infant formula, but not often drink infant formula. The carbohydrate content in infant formula is high, mostly lactose, so if adults are lactose intolerant, they usually cannot drink infant formula at this time, otherwise it may cause gastrointestinal discomfort, such as abdominal pain and diarrhea. Adults or the elderly can choose milk powder that meets their needs, such as skim milk powder or whole milk powder, to supplement high-quality protein as well as trace elements and vitamins. Adults can supplement their nutrition by drinking milk powder in moderation to ensure their body and bone development needs and help prevent osteoporosis, but milk powder is not a substitute for a normal diet, so you should eat vegetables, meat, eggs and other foods to provide energy and supplement nutrients.
