Chances are you know someone who is lactose intolerant. After all, about 20% of Caucasians, over 50% of Hispanic Americans, 75% of those of African descent, almost 80% of Native American Indians and 80% of Asians are lactose intolerant to some degree.
For most lactose-intolerant people, managing their condition often means avoiding dairy products altogether, even though most people can tolerate small amounts of lactose with no problem. As the amount of lactose consumed increases, however, the severity of symptoms usually increases. Researchers at the National Institute of Health noted this and decided to review the existing evidence to find out: first, what amount of lactose a lactose-intolerant person could consume on a daily basis without experiencing symptoms, and second, if any of the typical treatments could be said to work.
