Lactose intolerance is the lack of ability to digest the milk sugar or lactose. This inability cause s the most common gastrointestinal symptoms such as flatulence, cramps, bloating, and diarrhea in some individuals. When a person is lactose intolerant, it means that they don’t have enough of the lactase enzyme which breaks down milk sugar lactose into more simple sugars – glucose and galactose.
Infants and small children have these enzymes that break down lactose into glucose and galactose, which are then properly absorbed into the bloodstream, just because it’s natural to drink milk in infancy. Around 75 percent of grownups lose this ability along the way.
People of Asian origins are most common to lack the lactase enzyme, and Caucasians of European origin are the ablest to digest dairy products because of an inherited genetic mutation. Lactose intolerant individuals are often worried about their calcium levels. However, calcium is available in other food sources such as green leafy vegetables including broccoli, kale, and collards.
