Who is affected by lactose intolerance
Lactose intolerance is very common—approximately 50 million people in the United States have the condition.1 Worldwide, 70% of adults have some degree of lactose intolerance.2
Lactose intolerance occurs more often in Native Americans and people of Asian, African, and South American descent than among people of European descent. Experts believe that lactose intolerance is directly related to how long ago a person's ancestors were introduced to dairy products.
