What percentage of black people are lactose intolerant?

Why do African Americans have high rates of lactose intolerance?
Lactose intolerance in African Americans may be due to a genetic design. Research has shown that the proportion of people that are lactose intolerant can be tied to their region of genetic origin. Put simply, regions where dairy herds could be raised safely and efficiently produced people that could digest lactose.

What causes lactose intolerance in infants?
Lactose intolerance in infants is caused by a mutation of the LCT gene, resulting in life-long intolerance. In adults, the disorder is caused by decreasing activity of the LCT gene, resulting in an increasing inability to digest lactose as an individual ages.
What are the symptoms of lactose intolerance?
Lactose intolerance is generally harmless but its symptoms can cause extreme discomfort. Symptoms of lactose intolerance appear after consuming lactose or dairy and include: 1 Bloating 2 Abdominal cramps 3 Diarrhea 4 Gas

Can lactose intolerance be treated?

Can lactose intolerance cause osteoporosis?
Those who have lactose intolerance and need to avoid consuming dairy products run the risk of not receiving enough nutrients, specifically calcium and vitamin D. A lack of calcium can lead to osteoporosis, a condition in which one’s bones become brittle and more likely to break.

What is lactose intolerance?
Lactose intolerance is “an impaired ability to digest lactose, a sugar found in milk and other dairy products,” according to the National Institutes of Health (NIH). Lactose intolerance in infants is caused by a mutation in the LCT gene, which results in a life-long intolerance. This condition is inherited, rare, and most common in Finland.
Is lactose intolerance inherited?
This condition is inherited, rare, and most common in Finland. In adults, lactose intolerance is caused by normally decreasing activity of the LCT gene, which means adults may experience increasing inability to digest lactose as they age.
