Lactose intolerant people can eat lactose plums, but it is not a must. Lactose intolerance is caused by the lack of lactase enzyme that digests lactose, and patients show symptoms such as diarrhea, bloating and abdominal pain after eating dairy products. For people with lactose intolerance, taking lactose plum can digest and break down the lactose in the body into glucose and galactose, which can be absorbed by the intestines, thus reducing the symptoms of lactose intolerance. Lactose intolerant people can take lactose plums, but they can skip lactase if they don’t normally eat dairy products containing lactose, so lactase is not a must. If you need to take lactase, you should use the medicine under the supervision of a doctor. Lactase adverse reactions and contraindications have not been clarified, but if abdominal discomfort, flatulence, anorexia, nausea, vomiting and other symptoms occur during the use of the drug, you should stop taking lactase.
