In the case of insufficient breast milk for food safety reasons, many parents will give their newborn babies fresh milk instead of formula milk, is fresh milk really better than formula milk? Let’s take a look at the main components of the two types of milk in comparison. Protein: whey protein is better absorbed than casein For newborn babies it is generally not recommended to consume fresh milk directly because of the different protein bodies. Whey protein in breast milk is high and easily digested, while casein, although nutritious, is a type of curd that is extremely difficult to digest and break down, and excess casein can produce a high renal solute load. The formula, on the other hand, has adjusted the structure of the protein with reference to breast milk, which is more conducive to absorption than fresh milk. Fat: Fresh milk is mostly saturated fatty acids The fat in fresh milk is mainly animal saturated fat, which can stimulate the tender intestines of infants, causing chronic occult blood loss in the intestines and causing conditions such as anemia. Formula milk, on the other hand, replaces some or all of the saturated fatty acids with unsaturated fatty acids, making it more suitable for babies. Lactose: Lactose in fresh milk is not well absorbed The lactose in fresh milk is mainly alpha 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 The higher phosphorus content in fresh milk will affect the absorption of calcium. In addition, the content of iron does not meet the needs of infants, and as a result, can cause iron deficiency, which affects the physical and intellectual development of infants. Formula milk, on the other hand, is more suitable for babies as the mineral content is adjusted according to their physiological characteristics. Vitamins: Fresh milk is low in vitamins. Fresh milk is low in vitamins, which is far from meeting the normal needs of infants. The formula milk for baby needs to add some vitamins, trace elements, nucleotides, polyunsaturated fatty acids and other ingredients necessary for the growth and development of infants and children, more conducive to the healthy growth of children.
