Quizplus · Accepted Answer

Lactose intolerance is more common in areas that historically have not relied on dairy products, such as parts of Asia, Africa, and South America. This is due to a lower presence of the lactase enzyme in the population's genetic makeup, which breaks down lactose in dairy products.
