2. Lactose is a disaccharide found in milk. Many adults throughout the world get sick from drinking milk because they cannot digest lactose. Lactose intolerance varies markedly among various human populations. For example, only about 3% of people of Danish descent are lactose intolerant, compared with 97% of people of Thai descent. When someone who is lactose intolerant ingests milk, the lactose accumulates in the lumen of the small intestine because there is no mechanism for uptake of the disaccharide....
