Breastfeeding is not only beneficial to the baby's digestion and absorption, but also can increase the parent-child relationship and promote the baby's normal growth and development.
Now the benefits of breast milk are accepted by more and more mothers, and mothers begin to breastfeed their babies. So what do mothers know about breast milk?
According to the different periods of postpartum mother's milk secretion, breast milk can be divided into colostrum, transitional milk, mature milk and late milk.
"Colostrum" is the milk secreted by the parturient 7 days after delivery. As the baby's first bite of food, it is the most suitable and precious gift for the baby from the mother.
"Transitional milk" is the milk secreted by the mother 7- 14 days after delivery.
"Mature milk" is the milk secreted by the parturient from 2 weeks to 9 months after delivery. In fact, mature milk will not stabilize until 30 days later.
Finally, the milk secreted at postpartum 10 months is collectively called "late milk"
Among them, colostrum and mature milk are the most important for babies.
Why do you say that? This is because:
The proportions of protein, lactose, fat and minerals in breast milk are different in different periods.
Colostrum is small, dark yellow and sticky. It contains less fat, but there are many immune substances such as globulin, antibody, trace elements, calcium and phosphorus, white blood cells and so on. Compared with breast milk secreted in the later period, colostrum has stronger disease resistance, which is very important for neonatal development and anti-infection. It is the earliest oral immune antibody obtained by babies after birth, so colostrum is also called "liquid gold".
The duration of transitional milk is very short, but at this stage, the fat content of breast milk is the highest, and protein and minerals are gradually decreasing compared with colostrum. It is at this stage that many mothers experience lactation reflex, that is, "milk matrix". During the transitional lactation period, the breast will gradually adjust the lactation amount according to the amount of milk the child drinks.
The composition of mature milk is relatively fixed, and the ratio of protein, fat and sugar is 1: 3: 6. If the tacit understanding between the breast and the baby is high during this period, the balance between supply and demand can basically be achieved, and the situation of breast flatulence will be less. Of course, if there is breast swelling, it must be sucked out in time to prevent mastitis.
Finally, talk about late breast milk. The content of various components in late breast milk decreased, and the secretion decreased. But pure breast milk should be used for 8- 10 months as far as possible. If conditions permit, it is recommended to feed until the age of 2, but attention should be paid to adding complementary food in time to ensure the nutrition of children.
At each feeding, breast milk is divided into pre-milk and post-milk according to the order of milk secretion.
Pre-milk is the first milk produced by the mother during each lactation. Breast milk is low in fat and high in water, protein and minerals.
Pre-milk looks very thin and light, but it is rich in water and protein, which also makes exclusive breast-fed babies generally do not need to add extra water within 4 months after birth.
Post-milk is the whiter milk produced by the mother after each breastfeeding process. The protein content of post-milk gradually decreases and the fat content gradually increases, because it contains more fat and lactose and looks whiter than the former milk. These fats and lactose provide most of the energy for breastfeeding.
Every time a mother breast-feeds her baby, she must master the correct breast-feeding method, and take turns to feed the breasts on both sides, so that the baby can suck one side first and then the other side, so that she can eat enough front milk, ensure enough protein and try to eat enough back milk. If the fat is full and protein digests slowly, the baby won't be hungry too fast. If one side is not finished, she will change to the other side and come back later. Babies eat a lot easily.
According to the different nutrition and structure of mother's diet, breast milk is divided into thin milk and thick milk.
If mother's nutrition can't keep up, she will eat thinner food and have thinner milk. It doesn't matter if the milk is thin once or twice. If this continues, it may be difficult to meet the nutritional needs of children. Parents are advised to pay attention to whether their children's growth and development meet the standards at any time. Once the nutrition can't keep up, we should supplement some complementary foods rich in protein.
However, it is not good for mom to have too much nutrition. They eat too much fish and meat, and sometimes milk is covered with oil. Children who eat this milk can't digest it at all, and it is easy to have "fatty diarrhea"
So, mom can't make up for it. Meat, bean products, eggs, vegetables and fruits should be matched in proportion to ensure their nutritional intake. Just don't be picky about food. In addition, we should try to avoid spicy, irritating food, allergic food and alcohol during lactation.
Of course, in addition to diet, even the milk secreted by a breast is sometimes thick and sometimes thin, which is mostly caused by different constitutions or different nutritional status. Breastfeeding is not simple. Mothers must try their best to provide healthy and high-quality breast milk for their babies. In short, breast milk is specially made for their babies, and nothing can be replaced.
Breast milk is called "soft gold", and the nutrition in breast milk is irreplaceable by formula milk powder. Then the nutritional value of breast milk is high. Where is the height?
First of all, the nutritional content of breast milk is much higher than that of formula milk. There are about 400 known nutrients in breast milk, but only 50 in formula milk.
Secondly, breast milk is more suitable for newborns than formula milk. Newborns have delicate intestines and stomach, and the proportion of nutrition in breast milk is more suitable for baby's gastrointestinal absorption.
Breast milk has high electrolyte concentration and few protein molecules, which is more suitable for the condition of underdeveloped kidneys of newborns.
Third, there are more unsaturated fatty acids in breast milk, which is beneficial to promote the baby's brain development.
Fourth, in the process of breastfeeding, children can have close skin contact with their mothers. In addition, during breastfeeding, babies can smell their mothers and their eyes can see their faces. During the whole breastfeeding process, their sense of touch, sight and smell will receive information, which will be stored in their brains to stimulate their early brain development.
Therefore, we will say that breast-fed babies are smarter. Many times, it is not the credit of breast milk, but that breast-fed babies spend more time interacting with their mothers in the early life. The better the baby's brain develops.
Fifth, antibodies in breast milk can enhance children's immunity, while there are no antibodies in formula milk. There is a saying that children should eat breast milk within two hours after birth, because the flora on the mother's nipple can quickly help newborns establish intestinal flora. That is, the child's first immunization.
The reason why breast milk has high nutritional value is that breast milk not only contains the nutritional elements needed by the baby's growth and development, but also contains immune factors that enhance the baby's immunity. Especially colostrum, the mother's antibody will be given to the baby through breast milk, which can protect the baby from getting sick.
Breast milk provides more comprehensive nutrition. Breast milk contains natural nutrients, and the proportion is also suitable for the growth and development of babies, which ensures the complete metabolism of amino acids and will not accumulate too much phenylalanine and complex acids.
Moreover, breast milk will change with the baby's growth, and the nutritional components of breast milk are different in different months to meet the baby's needs. This is irreplaceable by any dairy product.
Second, breast milk can protect the health of babies. Colostrum and excessive milk contain a lot of immune factors, which can make babies immune. It can prevent allergic diseases, such as asthma and allergic eczema.
The content of lysozyme in breast milk is high, which contains many macrophages and can be directly sterilized. Lactose contributes to the growth of Lactobacillus and Bifidobacterium, and contains a lot of lactoferrin, which can inhibit the growth and activity of Escherichia coli, protect the gastrointestinal mucosa and enhance the resistance of gastrointestinal tract.
Studies have proved that breast-fed babies are much less likely to suffer from cardiovascular diseases and diabetes in adulthood than those who are not breast-fed.
Third, reduce sudden infant death. Breast milk is high in unsaturated fatty acids and easy to absorb. Lactose is the main sugar, which is beneficial to the absorption of calcium. The total osmotic pressure is not high and it is not easy to cause necrotizing enterocolitis.
Fourth, promote baby development. The content of cysteine and aminotaurine in breast milk is high, which is beneficial to the brain development of newborns and promotes intellectual development. The act of sucking can promote the development of language ability.
So breastfeeding is really good for the baby and good for the mother. It can not only enhance the relationship between mother and child, but also help mother to promote postpartum recovery. It can not only save family expenses, but also save worry and effort in feeding. It's good not to worry about inferior milk powder or bacterial infection.
Breast milk has corresponding high nutritional value at any stage of the baby. For example, from 0 to 7 days, we call it colostrum, which is a little yellowish and sticky and rich in protein, antibodies and immunoglobulin. It can help newborns with jaundice and allergies at this stage and lay a solid foundation for their growth in the next six months, which is why colostrum is called liquid gold.
Breast milk at 7- 15 days is called transitional milk, and the milk will gradually change from light yellow to milky white, which also provides the nutrition that the baby needs at this stage. /kloc-after 0/5 days, breast milk will become stable and mature milk, which will supplement all kinds of nutrients needed by the baby's growth, because breast milk itself will constantly change with the change of the child's growth stage, giving him all the nutrients he needs. This is also the reason why breast milk is not as good as milk powder. In particular, the fat content and calcium content in breast milk are many times that of milk powder, which is more conducive to the baby's absorption.
In the face of a baby who wants to add complementary food after six months, the activity of lysozyme in breast milk will be improved intelligently, which will greatly improve the gastrointestinal tract of the baby who adds complementary food and help him absorb and digest it better. Therefore, breast milk is the best gift for babies at every stage of growth.
Key points of breast milk nutrition: 0 ~ 7 days, pale yellow colostrum is called liquid gold; 7 to 15 days is milky white transitional milk; After 35 days, it is a mature species with rich nutrition; After six months, it will improve the activity of lysozyme and help the baby who adds complementary food to absorb and digest it better. So the nutritional value of breast milk at any stage is very high.
Hello! I am a breast milk mutual guide trained by the International Breast Milk Association and a midwife trained by the International Fertility Education Association. I will share the reasons for the high nutritional value of breast milk from my personal professional point of view, hoping to help all mothers.
Seeing other answers to this question, I answered very well. What are the nutritional components of breast milk and what are its benefits? Here, I want to talk about the reason why breast milk is widely recognized, and there is another very important value-the relationship between mother and baby.
Thanks for reading.
1. is beneficial to the digestion and absorption of infants. The absorption and utilization rate of nutrients in breast milk is generally higher than that of formula infant milk powder. Iron deficiency, zinc deficiency, indigestion and diarrhea are less serious.
2. Feeding is beneficial to the establishment of beneficial flora in infants' intestines. Almost all the large intestine of breast-fed babies are beneficial bacteria such as Bifidobacterium.
3. Enhance your baby's anti-infection ability. Infant's immune system is not yet mature, and human immunoglobulin, lactoferrin and other components in breast milk can provide effective defense system for infants.
4. Breastfeeding will reduce the anti-infection ability.
Breastfeeding is beneficial to the emotional, behavioral and intellectual development of infants.
6. It is beneficial to the health of future generations, and the risk of childhood obesity, hypertension and cardiovascular and cerebrovascular diseases in adulthood is lower than that of milk powder feeding children.
7. Breastfeeding is safe, economical and convenient, and it can also promote the recovery of the mother's uterus. In addition, breastfeeding can also help the breast empty milk and prevent breast swelling and mastitis. At the same time, breastfeeding can promote the feelings of mother and baby.
8. Breastfeeding is conducive to rebuilding the nutritional balance in the body.
The reason why breast milk has high nutritional value is because breast milk contains the following nutrients, which is very beneficial to the baby's brain development and physical growth.
1, carbohydrate
The carbohydrate in breast milk is mainly β-lactose, which is very important for infant brain development. In addition, β lactose can promote the effective absorption of nutrients in the baby's stomach.
2. Fat
In breast milk, fat is the main component in the middle and late stages, which contains a variety of digestive enzymes, which is beneficial to the development of baby's organ system.
3. protein
Protein is very important to human body and is the material basis of life. Protein in breast milk is mainly milk protein and ferritin. These substances can promote baby's digestion, inhibit bacteria and sterilize.
4. Fat
50% of the energy of breast milk is provided by fat. Breast milk contains less fat globules and more digestive enzymes. The fat content in breast milk is more beneficial to newborns and premature infants who lack pancreatic lipase.
5. Mineral elements and vitamins
Breast milk is rich in minerals. The absorption rate of zinc in breast milk can reach 59.2%. Zinc can promote baby's brain development. The iron content in breast milk is also very rich, and the baby absorbs it well. All kinds of vitamins in breast milk are enough to meet the needs of baby's physical development.
Step 6: Moisture
Breast milk contains enough water, mainly the front end of breast milk, which can meet the baby's daily water demand.
It can be seen from these that the nutrition of breast milk is very comprehensive and rich, which can meet all the nutritional needs of the baby's body. So those who can breastfeed try to breastfeed.
