The benefits of lactose for the body

The main property of lactose is that it is a substrate for the reproduction and development of bifidobacteria and lactobacilli, which form the basis of normal intestinal microflora. Thus, it is necessary for the treatment and prevention of various dysbiosis. Lactose is a source of energy in the body, a powerful stimulant of the nervous system. It has a positive effect on the development of the central nervous system in children, normalizes calcium metabolism, facilitating the absorption of calcium, and maintains the balance of intestinal microflora. Lactose belongs to the means of preventing cardiovascular diseases, improves the production of B vitamins and vitamin C, is a necessary component for the synthesis of various substances that impart viscosity to saliva.

What is "lactose intolerance"

Lactose can be harmful if the body does not have the ability to absorb it. This condition occurs when the enzyme lactase is deficient, it is called "lactose intolerance" (hypolactasia). In this case, this carbohydrate becomes dangerous for the body. Hypolactasia can be primary and secondary - acquired. Primary intolerance is almost always a hereditary genetic disorder. Acquired intolerance appears under the influence of the following factors: surgery on the stomach, intestines, dysbiosis, influenza, inflammatory diseases of the small intestine, ulcerative colitis, Crohn's disease, celiac disease, Whipple's disease, chemotherapy.

Lactose intolerance is manifested by abdominal pain accompanied by bloating, in some cases, severe flatulence leads to uncontrolled release of digestive gases. There is nausea, rumbling in the intestines, diarrhea, appearing one to two hours after eating dairy products or food containing milk. Lactose intolerance should not be confused with milk allergy. In case of allergies, this product should not be consumed at all, otherwise a person will develop characteristic symptoms: itching, skin rashes, clear nasal discharge, shortness of breath, swelling and swelling of the eyelids.

In hypolactasia, symptoms will depend on the amount of milk-containing product that has entered the intestines. With small amounts of lactose, the body will be able to break it down, in this case, there will be no symptoms of intolerance. If a person suffers from hypolactasia, you should not completely exclude milk and dairy products from the diet. The average safe dose of lactose is about 4.5 g per day, this amount is contained in 100 ml of milk, 50 g of ice cream or yogurt. For people who are completely intolerant of milk sugar, doctors prescribe calcium in combination with lactase.
