Lactose intolerance is very common. It is estimated that in the United States affects an estimated 50 million people. This type of sugar is not only milk but also in all dairy products.

Lactose intolerance can be primary, which is rare, or secondary to other diseases.

The reason for this intolerance is a deficiency of an enzyme, lactose, which is produced by cells in the intestine. The lactose is responsible for dividing the molecule of the milk sugar (a dis saccharides) into two smaller units so that they can be absorbed into the bloodstream.

In some cases the children are born with an inability to produce lactose. But more common is this deficiency that develops with the years. In humans, lactose production will decline with age, that’s why there are adults who are lactose intolerant to cow’s milk.

However, some vegetables such as broccoli, are rich in calcium and have very low in lactose. The same is true for fish such as salmon and sardines, shrimp and oysters. Also on soy cheese (tofu) is rich in calcium and low in lactose.
