Milk is a product made by mammals to feed their young. It is not surprising that it contains a large amount of nutrients, as well as vitamins and minerals necessary for the life of a small organism that cannot yet feed on its own. People most often eat cow's milk, which contains B vitamins, vitamins A and C, niacin, calcium, sulfur, fluorine, zinc, copper.
Vitamins in milk
Cow's milk is rich in vitamins that calves need for proper growth and development. But they are also useful for humans, especially in childhood. Scientists claim that this nutritious liquid contains all known vitamins that dissolve in water or fats. Most of the milk contains B vitamins: this is a very important riboflavin or B2, which is necessary for many biochemical processes in the human body; it is B12, which is known to be unable to be synthesized in the human body and is found mainly in animal products; this is B1, or thiamine, which is involved in metabolism. Also in milk there is B6, which strengthens the nervous system and increases efficiency.
Milk contains a small amount of vitamin A, which is insufficient to replenish the daily requirement of up to 900 mcg. However, this product can be used as an additional source of carotene, along with carrots, soy and legumes, liver and fish oil.
Vitamin C, a well-known ascorbic acid, is also present in milk, although milk is still a long way from plant sources of this antioxidant. Also contained in this animal product is vitamin PP, or niacin, which is involved in the oxidative reactions of cells, and biotin, which is contained in enzymes that regulate metabolism. For expectant mothers, folic acid is very useful, which is also in milk, it allows the child to develop normally in the womb.
It is necessary to understand that there are fewer fat-soluble vitamins in skim milk.
Trace elements in milk
In addition to organic substances, vitamins, milk contains a huge amount of inorganic compounds in small, but important quantities for the human body. First of all, it is calcium, which serves as a building material for the formation of the musculoskeletal system. A liter of milk contains the daily intake of calcium for humans, including children, who especially need this trace element.
The rest of the minerals are not so well known, but in small quantities are also important for the proper functioning of the body. These are fluorine, copper, zinc, manganese, bromine. Even aluminum, titanium, silver, tin are contained in milk. It contains compounds of potassium, magnesium, sodium, phosphorus, iron.
Milk, according to researchers, contains about 200 useful substances, in addition to vitamins and minerals, these are fatty acids of several types and lactose - milk sugar.
