Everyone knows that for newborn babies, breastmilk is the best baby food. In the case of insufficient breast milk, it is necessary to consume formula milk powder. Generally, it is not advisable to eat fresh milk directly. Why is this?
Protein: Whey protein is better absorbed than casein
The ratio of whey protein to casein in breast milk is 60:40, while the ratio of whey protein and casein in normal milk is 18:82. Whey protein is easily digested, and the bioavailability of protein is high, which effectively reduces the burden on the kidneys. Although casein is nutritious, it is a very difficult-to-digest and decompose curd. Excess casein will produce higher renal solute load. Formula milk, with reference to breast milk, adjusts the structure of the protein and is more conducive to absorption than fresh milk.
Fat: Fresh milk is mostly saturated fatty acid
The fat in the milk is mainly animal-saturated fat, which stimulates the baby's delicate intestinal tract, causes intestinal chronic hemorrhage, and causes anemia and other illnesses. In addition, the composition of fatty acids in fresh milk is significantly different from that of breast milk. In particular, the lack of fatty acid, linoleic acid, necessary for the growth of infants is not conducive to newborn babies. Part of or all of the formula milk replaces saturated fatty acids with unsaturated fatty acids, which is more suitable for babies.
Lactose: Lactose in fresh milk is not well absorbed
Lactose in fresh milk is mainly alpha-type lactose, which inhibits bifidobacteria and promotes the production of E. coli, which can easily induce gastrointestinal diseases in infants.
Minerals: formula milk is more reasonable
Milk contains a high amount of minerals, and the ratio of calcium to phosphorus is also detrimental to the baby's physiology. Higher levels of phosphorus in fresh milk can affect calcium absorption. Due to the imperfect development of your baby's kidneys, too much inorganic salt will increase the burden on the kidneys. In addition, the content of iron can not meet the needs of infants. As a result, iron deficiency can be caused, which affects the physical and intellectual development of infants. The formula milk adjusts the mineral content according to the baby's physiological characteristics and is more suitable for the baby.
Vitamin: Fresh milk has low vitamin content
The vitamins A, C, D, and E contained in fresh milk are very low and far from meeting the normal needs of infants. Formula milk is for the baby needs to add some vitamins, trace elements, nucleotides, polyunsaturated fatty acids and other essential ingredients for infant growth and development, to overcome the shortcomings of fresh milk, more conducive to the healthy growth of children.
