What is Lactose Intolerance?
Lactose intolerance is the body’s inability to digest significant amounts of lactose, the major sugar found in milk. Lactose intolerance is caused by a shortage of the enzyme lactase, which is produced by the cells that line the small intestine. This enzyme breaks down milk sugar into two simpler forms called glucose and galactose, which are then absorbed into the bloodstream. This site also discusses how to balance lactose intolerance with nutrition and eating healthy foods, and how lactose intolerance can be treated.
