Lactose intolerance
Lactose intolerance is a condition wherein an individual cannot digest lactose, a sugar found in milk. When a lactose intolerant individual ingests any form of milk, he or she may experience extreme stomach discomfort as well as other symptoms such as cramping and bloating. Such individuals do not produce an enzyme called lactase that breaks down lactose after weaning.[1]
The proportion of lactose intolerant individuals varies by region on the planet. 99% of Chinese are lactose intolerant, whereas only 10% of Americans are. Recent research indicates that lactose intolerance is high where cows were not domesticated. [2]At higher latitudes, lactose intolerance decreases. As average temperature increases, lactose intolerance increases.[3]
Lactose tolerance is determined by a recessive gene. Researchers have recently identified a DNA mutation that allows people to tolerate milk.[4] Lactose tolerance is often called lactose persistence.
