- Lactose intolerance is caused by reduced production of the enzyme lactase. A variety of digestive system problems, such as celiac disease and Crohn’s disease) can also lower the production of lactase. If an individual produces low levels of the enzyme lactase, explain why they might be able to tolerate eating dairy products that contain lower levels of lactose (e.g., hard cheeses, feta cheese, and cottage cheese), but will not be able to tolerate foods with high levels of lactose (e.g., milk).arrow_forwardIn healthy adults, the concentration of glucose in blood is approximately80 to 110 milligrams per deciliter (mg/dl).
