HUMAN NUTRITION

Detailed explanation-1: -Lactose malabsorption is a condition in which your small intestine cannot digest, or break down, all the lactose you eat or drink. Not everyone with lactose malabsorption has digestive symptoms after they consume lactose. Only people who have symptoms are lactose intolerant.

Detailed explanation-2: -Diseases associated with secondary lactose intolerance include intestinal infection, celiac disease, bacterial overgrowth and Crohn’s disease. Treatment of the underlying disorder might restore lactase levels and improve signs and symptoms, though it can take time.

Detailed explanation-3: -The body digests lactose using a substance called lactase. This breaks down lactose into two sugars called glucose and galactose, which can be easily absorbed into the bloodstream. People with lactose intolerance don’t produce enough lactase, so lactose stays in the digestive system where it’s fermented by bacteria.

Detailed explanation-4: -The most common type of carbohydrate intolerance is lactose intolerance due to a primary insufficiency of the lactose digesting enzyme, lactase.

Detailed explanation-5: -If people with lactose intolerance eat dairy products, the lactose from these foods pass into their intestines, which can lead to gas, cramps, a bloated feeling, and diarrhea. Some people can have small amounts of dairy without problems. Others have a lot of stomach trouble and need to avoid all dairy products.
