Does milk really have miraculous nutrition and efficacy, and what is the nutrition of human milk?

Breast milk is the only most natural, safest and most complete natural food for infant growth, which is rich in nutrients and contains all the nutrients and antibodies needed by babies to ensure the normal and healthy development of infants. Some mothers give up breastfeeding due to busy work or lack of physical strength, resulting in insufficient nutrition and weak constitution for their babies. In addition, correct feeding methods are also important.

1.Moisture: The moisture content of milk is about 87%.

6.Vitamins: Milk contains a variety of vitamins, including vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B2, vitamin B6, etc.

Among them, vitamin D contributes to the absorption and utilization of calcium, while vitamin B2 and vitamin B6 contribute to the body's metabolic and immune functions.

Milk is a very nutritious food with nutritional value in the following aspects:

1.Provide high-quality protein: The protein in milk is a very high-quality protein, and its amino acid composition is relatively close to the amino acids required by the human body, which is easy to be absorbed and utilized by the human body.

1.Provide high-quality protein: The protein in milk is a very high-quality protein, and its lack of amino acid composition is relatively close to the amino acids required by the human body, which is easy to be absorbed and utilized by the human body.

1.Provide high-quality protein: The protein in milk is a very high-quality protein, and its amino acid composition is relatively close to the amino acids required by the human body, which is easy to be absorbed and utilized by the human body.

2.Protein: Milk contains a variety of proteins, the most important of which are whey, egg and casein.

Whey protein is a high-quality protein that is easy to digest, while casein is a slow-absorbing protein. In addition, milk also contains small amounts of collagen and immunoglobulins.

The nutritional content of breast milk mainly includes the following:

1. Protein.

Protein is one of the five major nutrients of breast milk, breast milk contains a low amount of protein composed of casein and lactalbumin, casein can provide amino acids and inorganic phosphorus for the baby, and - lactalbumin, lactoferrin, lysozyme, albumin as the main components of lactalbumin, rich in essential amino acids, high nutritional value, baby smoking in the stomach to form a small clot, conducive to digestion and absorption.

2. Carbohydrates.

Carbohydrates, one of the five major nutrients of breast milk, are the main caloric energy of babies within 6 months**, because the lactose concentration it contains is higher than that of milk.

3. Vitamins.

Breast milk contains more vitamins A, E, C and a small amount of vitamins B1, B2, B6, B12, K, folic acid, which can meet the general needs of babies, but it should be noted that the content of vitamin D is very low in both human milk and cow's milk, and it generally needs to be supplemented.

4. Fat. Breast milk contains fat, which exists in the form of emulsion with fine particles (diameter "10 m"), because its volatile short-chain fatty acids are 7 times less than milk, long-chain unsaturated fatty acids are more, and the oleic acid content that is easier to absorb is twice as much as that of cow's milk, because it is easy to digest and absorb, it is very suitable for babies to eat, 5. Minerals.

The mineral content of breast milk is about 1 3 of cow's milk.

1. The calcium and phosphorus content (33:15) is lower than that of cow's milk (125:99), but the proportion is easier for the baby to absorb, so human breastfed infants are less likely to have hypocalcemia; Second, although the zinc content in breast milk is lower than that of cow's milk, because of the presence of a small molecular weight ligand (ligand) combined with zinc, it can promote the absorption of zinc, and the zinc in milk is combined with large molecular weight protein, which is not easy to absorb, so the zinc bioavailability of breast milk is relatively higher; Third, the absorption rate of iron in breast milk is significantly higher than that of cow's milk, but it is necessary to supplement iron by adding complementary foods and iron foods to avoid iron deficiency anemia.

0 has so many substances that the human body needs, of course, there is nutrition.

Milk has a high nutritional value, it is rich in protein, trace elements, calcium, and improves immunity required by the human body.

Breast milk is the best, most suitable and safest food that babies naturally have for the first few months of life. Exclusive breastfeeding can fully meet all the nutritional needs of the infant up to 6 months of age.

Breast milk contains more than 400 components, which change from moment to moment, including the composition of each period, the amount of secretion, and even the composition of each drop.

The milk secreted by the mother within 4-5 days after delivery is colostrum; 6-10 days for transitional milk; Milk from 11 days to 9 months is mature milk; After 10 months, it is called late breastfeeding. Colostrum is small, light yellow, high in protein (mainly immunoglobulins) and low in fat, rich in vitamin A, taurine and minerals, and contains colostrum globules, which are very important for the growth and development of newborns and their ability to resist infection.

How high is the nutritional value of breast milk?

1. Rich in nutrients, appropriate proportion, easy to digest and absorb. Among them, there is more albumin and less casein, which forms a small clot in the stomach and is easy to absorb; It contains more polyunsaturated fatty acids, small fat particles, appropriate calcium and phosphorus ratio, more lactose, more trace elements such as zinc, copper, iodine, and breast milk iron is easy to absorb, and contains more digestive enzymes such as amylase, lactase, etc., which is helpful for digestion;

Second, the protein of breast milk is mainly whey protein, which is the whey protein of human beings, and the amino acid arrangement in breast milk is also the structure of human beings, which is the substance that babies need most. Breast milk has more high-quality protein, essential amino acids and lactose, which is conducive to the development of infants;

3. Breast milk contains substances that promote immunity, such as immune cells, immunoglobulins, lactoferrin, bifidus and other immunoglobulins, which can effectively prevent and protect infants from infection and chronic diseases.
