What are the nutrients of breast milk and what nutrients does breast milk contain

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.

Breast milk contains nutrients that cannot be replaced by any artificial product. In other words, no milk powder can replace mother's milk, but many mothers do not understand what specific nutrients are good for their babies in breast milk. So what are the nutrients of breast milk?

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. If your baby consumes less protein, it can lead to a weakened immune system. And it may also lead to anemia, so breastfeeding is good for the baby, and the mother should give the baby milk as soon as possible.

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, the main substance in breast milk fat is linoleic acid, which can make the baby smart.

3. Lactose. In addition to being rich in fat and protein, breast milk also contains lactose, we know that sugar is also the main energy of the human body, but like glucose or fructose contained in milk powder, the baby does not absorb it very well, but breast milk is different, and the sugar contained in breast milk is also lactose, and the baby can absorb it well. Breast milk is rich in nutrients, and mothers should try to breastfeed their babies.

The nutritional content of breast milk can be said to be very high, insulting the nutritional content, which is basically the same as the composition of our human body, which includes seven major nutrients. Including fats. Protein.

Carbohydrates. Dietary fiber. Minerals.

Water. There are also vitamins contained in breast milk with these seven hard elements. And its nutritional mix is relatively uniform, which is very helpful for the growth of young children.

It can provide sufficient and comprehensive nutrients for the growth of young children.

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 is formulated with SN-2

PLUS affinity structural fat with natural milk fat 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.

Breast milk contains those nutrients.

Protein: Lactalbumin in breast milk accounts for more than 70% of the total protein, lactalbumin can promote the synthesis of sugar, and the clot formed after encountering acid in the stomach is small, which helps digestion.

Amino acids: Breast milk contains more taurine, which can bind to bile acids and plays an important role in the digestion process, which maintains the stability of cells.

Fat: Breast milk has few fat globules and contains a variety of digestive enzymes that aid in the digestion of fat. The unsaturated fatty acids in breast milk also help with the development of the baby's brain and nerves.

Lactose: The lactose contained in breast milk can promote the development of the baby's brain, and it will also be used by lactic acid bacteria in the intestine to produce lactic acid, which in turn promotes the absorption of calcium in the gastrointestinal tract and inhibits the growth of harmful bacteria.

Inorganic salts: The ratio of calcium and phosphorus in breast milk is 2:1, which is easy to absorb and has a certain effect on the prevention and treatment of rickets.

Minerals: The mineral content of breast milk is more conducive to the absorption of the baby's kidneys and gastrointestinal tract, and the absorption rate of iron can reach 50%.

Immune-active substances: Breast milk is rich in immunoactive proteins, such as lactoferrin, lysozyme, etc., which can help fight digestive and respiratory diseases.

In addition to the important lactoferrin, breast milk also contains carbohydrates, proteins, fats, vitamins, minerals, fatty acids and taurine, which are balanced to meet the needs of the child's growth and can be configured according to the baby's age. Breast milk also contains some enzymes, antibodies, growth factors and other components that cannot be mimicked in formula. Therefore, breast milk, especially newborn breast milk, is highly nutritious.

In fact, the nutrients in breast milk are very comprehensive, and breast milk contains all the nutrients that babies need, so they need to breastfeed, breastfeed, and breastfeed nutrition.
