What is the role and efficacy of breast milk The nutritional content of breast milk

Water – the main component of breast milk. Therefore, breastfed babies can get enough water from breast milk without supplementation. This is true even if the weather is hotter.

Easier to digest protein – The protein contained in breast milk is almost digested by infants. That's why breastfed babies have heavier stools than babies who don't breastfeed. This is also the reason why they are fed more often.

1. Vitamins: The normal nutrition of breast milk contains more vitamins A, E and C, while the content of vitamins B1, B2, B6, B12, K and folic acid is less, but it can meet physiological needs. The content of vitamin D in human milk and bovine milk is low.

3. Fat: It exists in the form of emulsion with fine particles (diameter < 10 m), in which the content of oleic acid lipids that are easier to absorb is twice that of milk, and the volatile short-chain fatty acids are 7 times less than that of milk, and there are more long-chain unsaturated fatty acids, which are easy to digest and absorb.

4. Protein: Human milk has a low protein content and is composed of casein and lactalbumin, the former providing amino acids and inorganic phosphorus. Lactalbumin accounts for about 2 3 of the total protein, and the main components are - lactalbumin, lactoferrin, lysozyme, albumin, rich in essential amino acids, high nutritional value, small clots formed in the stomach, conducive to digestion and absorption.

How much do you know about the five major nutrients of breast milk?

5. Minerals: The mineral content of human milk is about 1 3 of cow's milk. Calcium and phosphorus content in human milk (33:

15) It is lower than cow's milk (125:99), but the ratio of calcium and phosphorus is appropriate (2:1 for human milk, and 2:1 for milk

1) Calcium absorption is good, so hypocalcemia is less common in human breastfed infants. The content of iron in human milk and cow's milk is low, but the absorption rate of iron in human milk is significantly higher than that of cow's milk. However, if complementary foods and iron-containing foods are not added in time, iron deficiency anemia is still prone to occur.

The zinc content of human milk is lower than that of cow's milk (human milk, cow's milk but its bioavailability is high, because there is a small molecular weight ligand in human milk that binds to zinc, which can promote the absorption of zinc, and the zinc in milk is combined with a large molecular weight protein, which is difficult to absorb. If you are a mother with less breast milk, you can choose synbiotic milk powder, which uses SN-2 plus affinity structural fat with natural milk fat, which is closer to the structure and proportion of breast milk fat, and clinical experiments have proved that the feeding effect is closer to breast milk.

1. Protein. Breast milk is rich in protein sodium cryptoplasm, and whey protein is the main one, with less casein content, which is easy to digest and absorb. Breast milk is also rich in taurine, which is conducive to the development of the neurological system of infants and young children.

2. Fat. Breast milk is relatively high in fat, mainly short-, medium- and long-chain fatty acids, linoleic acid and linolenic acid, which are easy to digest and absorb. Breast milk also contains unsaturated fatty acids, which can promote the development of the nervous system in infants and young children.

3. Sugars. The lactose content in breast milk is 5% to 8%, which can provide energy. Lactose is used by lactic acid bacteria in the intestine to produce lactic acid, which inhibits the growth of harmful bacteria.

4. Vitamins, the number of ashwagandha and minerals. Breast milk contains vitamin C, B vitamins, vitamin A, etc., and the content of vitamin D is relatively small. Breast milk also contains zinc, copper, calcium, phosphorus, etc., and the appropriate ratio of calcium and phosphorus is more conducive to the absorption of calcium, which can promote the bone development of infants and young children.

5. A variety of immune factors. Breast milk contains a large amount of immunoglobulins, such as SIGA and IgM, and colostrum contains a small amount of IgG. The immune substances in breast milk also include macrophages, lactoferrin, lysosomes, bifidus, etc., which can enhance the immunity of newborns after birth.

6. Hormones and growth factors. Such as epidermal growth factor, nerve growth factor, insulin-like growth factor, etc., can regulate the growth and development of infants and young children. At the same time, it also contains thyroid hormones, prostaglandins and other substances, which can maintain, regulate and promote the growth and development of various organs of infants and young children.

When mothers breastfeed their children, they actually know that if they insist on feeding their children, such as these breast milks, will help the children's health to a certain extent. However, some children may also feel a pair of nutritional absorption and some breast milk in the process of drinking breast milk, and their taste is actually different. Therefore, in view of these aspects, it is also recommended that some mothers must eat more vegetables and some crucian carp soup in their daily life.

Physical health helps to a certain extentThese healthier foods can also help themselves, and then in the process of feeding the children, let the children supplement some vitamins or some healthier substances through these breast milk. Many people will be curious about what nutrients are contained in these breast milks. In the process of feeding children, can they let them grow their bodies, and also solve their satiety?

Some healthier substances are actually like this breast milk, but it does contain a lot of nutrients, first of all, it is the well-known lactoferrin, and in addition to such an element, there are some other various nutrients. For example, carbohydrates and fats, vitamins, etc., which contain calcium, and proteins and minerals, etc., are also in these breast milk, which means that such a breast milk actually contains a variety of nutrients.

It is of great significance to the growth of children, but we should also pay attention to it in the process of feeding, and we must let the baby feed in a very comfortable environment. Otherwise, the children may not be in the right position, which may lead to choking or feeling very uncomfortable. In addition, it is important to keep it clean, otherwise it may breed some bacteria, or there may be some pain in the process of eating for the children, etc.

Breast milk contains nutrients such as proteins, amino acids, fats, lactose, inorganic salts, minerals, and immunoactive substances.

Your baby's brain development is mainly based on lactose. In addition, breast milk also contains beta-lactose, which can indirectly inhibit the growth of E. coli.

1. Protein.

There are many ingredients in life that contain protein, and breast milk is rich in protein, which is more suitable for babies and can meet the needs of their growth and development.

2. Fat. Fat is an essential substance for human metabolism, is the main energy of the human body, the nutrients in breast milk are mainly fat, in addition to meeting the baby's metabolic needs, but also to promote the development of the baby's intelligence.

3. Lactose. Breast milk is rich in fat and protein, as well as lactose.

Breast milk is rich in protein and various minerals, trace elements and vitamins, and the nutrition of breast milk is very high, and it is the most natural food.

The nutritional composition of breast milk is known, and there are elements that have not yet been discovered, but it is certainly better than the nutrition of milk powder, milk powder has limited nutrition, although milk powder has something to improve the baby's immunity, but breast milk also contains.

Breast milk contains nutrients such as fat, protein, lactose, vitamins and minerals that are easy for babies to digest and absorb.

The first is protein, which is composed of complex protein and whey protein, mainly whey protein, which is rich in essential amino acids, high nutritional value and conducive to digestion and absorption.

Second, carbohydrates, the main carbohydrate in breast milk is lactose, and human milk has the highest lactose content of all mammals, providing 40% of the baby's energy needs.

Third, fat, is the most variable component of human milk and provides up to 50% of calories.

Fourth, vitamins are normal nutrition of pure breast milk, with high levels of vitamins A, C, and EJ. The content of vitamins B1, B2, B6, B12 and folic acid is less, but it can meet physiological needs.

Fifth, the absorption of inorganic salts, human milk calcium, phosphorus ratio of undecacium, so human milk fed infants are less likely to develop hypocalcemia.

Sixth, water, water accounts for breast milk, and the water in breast milk is enough to meet all the water needs of the baby, even in hot and dry climates.
