Comparison of the nutritional value of cow s milk and breast milk

There is no comparison, the nutritional value of breast milk in the first 6 months is the best, and there are a large number of substances that enhance children's immunity, which can effectively avoid the risk of children's disease, and the nutrition gradually decreases in 6 months, and then milk powder or goat milk powder (freshly squeezed milk and goat milk are not good, the milk particles are large and not processed at all, and the goat milk can be absorbed, but it is unhygienic to deal with it yourself). After the age of 1, the milk in the box of the brand on the market is nutritious enough, so drink it with confidence.

Many mothers think that breast milk is the same during breastfeeding, but it is not. Breast milk is magical. It changes according to each stage of the baby's growth and is constantly adjusted to suit the baby. Therefore, the nutrient content and proportion of breast milk are different at different times.

Do you know? Do you know? Different stages of breast milk have different nutrient profiles.

Breast milk can change as your baby grows, but mothers can't tell if breast milk is nutritious by the color and thickness of breast milk alone.

Colostrum, transition, mature and late milk.

1.Colostrum: Milk for 7 days after giving birth.

The concentrations of sodium, potassium and chloride in colostrum are higher than those of mature milk, and the proportion of protein, vitamins, minerals and antibodies is higher than that of mature milk. Colostrum is a good protective barrier for newborns.

Colostrum also has a laxative effect, which can promote the elimination of meconium and reduce neonatal jaundice. Colostrum is also low in fat, which is very beneficial for newborns with poor gastrointestinal growth.

2.Transitional milk: 7-14 days postpartum milk.

Breast milk between colostrum and mature milk is transitional milk. This period is short, but it is during this stage that breast milk has the highest fat content and a gradual decrease in protein and minerals.

3.Mature milk: 14 days postpartum.

The composition of mature milk gradually stabilizes, especially the protein remains at a fairly constant level. Although mature milk contains less protein than colostrum, it is superior to other milk due to the proper ratio of various protein components, rich in fats and carbohydrates, vitamins and trace elements, and enzymes and immune substances that aid in digestion.

4.Late milk: 10 months postpartum milk.

Over time, your baby's growth can no longer be completely dependent on breast milk. The amount of milk in the later milk is reduced, and the nutrients in the breast milk are also reduced. This is a natural regulation system, and the nutrition of the milk changes with the baby.

Even if the same breastfeeding process is divided into fore, middle and hind milk, there will be subtle variations, including changes in the colour and concentration of the milk.

The foremilk is high in protein and the hind milk is high in fat. The milk in front contains more water, sugar, and protein. Just like an appetizer, the high fat content of the back milk tells you that your baby is full.

It's a magical mother-child exchange. It is impossible to do this with a formula, because the formula has not changed at all.

About foremilk and hindmilk.

Breast milk can also be divided into foremilk and hindmilk. Pre-milk contains protein, lactose, vitamins, inorganic salts and a lot of water, mainly for the baby to "quench thirst"; The milk is high in fat, mainly to "relieve hunger" for the baby.

Every time the mother feeds, the baby can eat the front milk and the back milk to ensure that the baby has enough nutrition.

The protein, fat and other nutrients in milk are very suitable for babies. But mothers need to add complementary foods according to their baby's growth to meet all of their nutritional needs.

There are differences in the nutritional value of breast milk, not all mothers' breast milk is the same, different physique, different nutritional conditions, or different stages of milk production of the same mother, the breast milk obtained is not the same.

The nutritional value of breastfeeding is determined according to the mother's physique, during the lactation period, the mother's physique is better and nutritious, the nutritional value of pregnancy and lactation is high, if the mother's physique is poor and the nutrition is insufficient, the nutritional value of breastfeeding is also low.

Because breast milk contains proteins, fats, vitamins, trace elements, and sugars, it tastes sweet, not salty. However, each woman's physique and nutritional status are different, so the proportion of nutrients in breast milk will be different.

Some breast milk contains a lot of fat, and at this time, you can see that the breast milk is particularly thick, while some breast milk contains less fat, but more protein and sugar, although the color is lighter, but the nutritional value is particularly high.

Breast milk Breast milk begins after childbirth as colostrum, then transitional milk, and after 3-7 days it becomes mature milk, and breast milk has many advantages.

1. The composition of breast milk is most suitable for the needs of newborns and premature infants: the ratio of whey protein and casein in the protein is 7:3, the milk curd formed is the smallest, easy to quiet, and the amino acid metabolism is complete, so as not to retain too much phenylalanine and tyrosine.

Both cystic acid and amino-vico-taurine are high in human milk. Human milk is high in unsaturated lipotic acid, which is easily absorbed, and calcium absorption increases. Sugars are mainly lactose, which helps the absorption of calcium and magnesium, the total amount of minerals is not high, and the ratio of calcium and phosphorus is appropriate.

The permeability of the main lane of human milk is not high, which is not easy to cause necrotizing enterocolitis and does not increase the burden of the kidneys.

The protein content of breast milk of full-term infants is low in sodium, zinc, copper, etc., which cannot meet the needs of preterm infants. Breast milk for premature infants:

1) High protein, the protein of breast colostrum before gestational age 34 weeks is high, which is conducive to the rapid growth of premature infants, and the premature breast milk has higher protein quality, which is suitable for the needs of premature infants of different gestational ages. Premature babies have a strong ability to digest protein and can adapt to breast milk with high protein content.

2) The amount of fat is lower and easier to absorb.

3) Lactose is low in carbohydrates. Indicated for preterm infants with low lactase activity.

4) The sodium salt is high, which is conducive to the early excretion of relatively large sodium in the extracellular fluid in preterm infants.

5) High calcium and phosphorus, which is conducive to bone growth.

6) Although the total caloric energy is low, the preterm infant is less active and has less caloric energy requirement.

2. Breastfeeding can enhance disease resistance: colostrum and transitional milk have high secretory type, which can enhance the disease resistance of the gastrointestinal tract. Breast milk is high in lysotropin and has many macrophages, so it can be directly sterilized.

There is a lot of lactoferrin in breast milk, which can inhibit the growth and activity of E. coli, and also directly protect the intestinal mucosa, so that the mucosa is protected from the invasion of bacteria. Babies breastfeed directly, and the milk is not easily contaminated.

3. Breastfeeding can enhance the relationship between mother and baby: so that the baby can get more maternal love, enhance the sense of security, and grow up with a more cheerful and approachable personality. There are many factors that contribute to the formation of character, but breastfeeding is one of the most important.

Rooming-in in maternity homes and increased direct contact between babies and mothers can improve the success rate of breastfeeding.

Milk. Cow's milk is nutritious and a good food for babies, but it has many disadvantages compared with human milk

1. The milk protein content is too high, which increases the burden on the kidneys.

2. The ratio of whey protein to cool protein is not appropriate, which is easy to produce transient hypertyrosinemia and hyperphenylalanine acidemia, which has an impact on development.

3. Saturated fatty acids in milk are high, which is not easy to digest and absorb, and the stomach empties for a long time.

4. The lactose in the sugar is low, and the proportion of calcium and phosphorus is low, which affects the absorption of calcium.

5. Milk is high in minerals, increasing urine osmotic pressure.

Preterm infants fed cow's milk are susceptible to late metabolic acidosis. Newborns are now rarely fed with pure cow's milk and are replaced by formula milk.

Raw milk. Raw milk refers to freshly squeezed milk that is boiled before drinking. Milk is rich in immunoglobulins, which can effectively resist viruses and supplement the calcium necessary for growth and development, and is suitable for growing children, adolescents and the elderly.

The chemical composition of milk varies depending on the type of cow, its age, feeding method, time of arrival, and health status. According to the analysis, every 100 grams of cow's milk contains:

moisture in grams; protein grams;

fat grams; carbohydrate grams;

ash decigrams; mg of calcium; phosphorus mg; iron mg;

thiamine mg, riboflavin mg, vitamin A140 IU;

niacin mg, ascorbic acid mg;

Milk is a complete protein food, containing 8 kinds of amino acids necessary for the human body, about 40% of its protein is casein, and only 13 mg per 100 grams of milk fat is also available, and it also has the effect of lowering cholesterol.

Its taste is sweet, flat and slightly cold. The medicinal effects are to replenish deficiency, benefit lung qi, moisten **, detoxify fever and moisten the intestines. Dietary Therapy:

1) Cure physical weakness and lack of qi and blood.

Milk boiled rice, jujube porridge, often eaten.

2) Treatment of gastric and duodenal ulcers.

Boil 500 grams of milk, add 50 grams of honey, 10 grams of baiji powder, 1 time a day.

3) Treatment of habitual constipation.

250 grams of milk, 100 grams of honey, a little green onion juice, boil, take it on an empty stomach in the morning.

The difference between the composition of cow's milk and breast milk.

Milk and breast milk are two ways to feed the baby, and now people are disturbed that Bi has realized the benefits and advantages of breastfeeding, it can be said that more and more women have joined the breastfeeding army, but there are still some people who do not understand the difference between the two. So, what is the difference between the composition of cow's milk and breast milk?

There is definitely a certain difference in the composition of cow's milk and breast milk. To put it simply, the protein in breast milk is relatively low. Glycine, this ingredient is only found in slippery milk, and it is not found in breast milk.

Breast milk contains higher milk protein than casein, but the opposite is true in cow's milk.

Looking at the protein in milk and breast milk, although both are relatively rich in protein, the two are not the same. The protein contained in breast milk is easily digested by the baby, and it usually takes more than an hour to digest it. However, the protein in milk is more difficult to digest, and the specific time required is about three hours.

Breast milk also contains nutrients that are not found in cow's milk. This ingredient is taurine, which can help and promote the baby's brain development from the perspective of efficacy. This is a valuable nutrient in breast milk.

In addition to the sugar content of these breast milks, they are also better than cow's milk, so breast milk is more suitable for feeding babies.

According to the order of breast milk production, there are two types of milk: foremilk and aftermilk. When breastfeeding, you should never express the initial milk, and only eat the aftermilk, which will lack water and protein. This is because the milk that comes out first is called "foremilk", although it looks thinner, it is rich in water and protein, which also makes it easy for exclusively breastfed babies to generally do not need additional water in the first 4 months of life.

The milk after the "foremilk" becomes white and thicker, which is the "aftermilk". Milk is rich in fat, lactose and other nutrients, providing many calories and ensuring that your child will not be hungry as often as possible.

There will be different nutrient absorption, but also contains different nutrients, will produce different nutritional value, human development will also have different effects, there will be different substances.
