由于小孩子生长发育速度快,因此有这样的说法:“小孩子每天都不一样”,尤其是刚出生的小孩。新生儿期是人生的开端,又是一生中生长发育最快速的阶段,尤其是大脑发育最迅速的时期,故需要高质量营养。但新生儿的消化功能尚未发育完全,母乳则是母亲专为自己婴儿生产的最理想、最适宜的天然食品,能提供小孩子快速生长发育所需的营养物质,从质和量上均符合新生儿的生理需求。母乳中所含的优质蛋白质中乳白蛋白含量最高,在胃中形成的乳凝块小,易于小孩子的胃肠道消化吸收;母乳中所含脂肪以不饱和脂肪酸为主,而且还含有降脂糖,有利于脂肪的消化吸收,其吸收率大大高于其他乳类;母乳中的乳糖为β型乳糖,在体内能分解成半乳糖。母乳中的营养物质不仅能满足小孩子体格生长需要,还是小孩子大脑发育必不可少的“原料”,为小孩子智力开发打下良好的物质基础。所以人们称 As children grow and develop fast, so there is such a saying: “children every day is different,” especially the newborn child. Neonatal period is the beginning of life, but also the fastest growing stage of life growth, especially in the brain is the most rapid period of development, it requires high-quality nutrition. However, the digestive function of newborns has not yet fully developed, breast milk is the mother ideal for their own baby production of the best, most suitable natural food, can provide children with rapid growth and development of nutrients needed, qualitative and quantitative are in line with the new Children’s physical needs. Breast milk contains high-quality protein in the highest content of lactalbumin in the stomach to form a small clot, easy to digest and absorb the gastrointestinal tract in children; breast milk contains mainly unsaturated fatty acids, but also contains lipid-lowering Sugar, is conducive to the digestion and absorption of fat, its absorption rate is much higher than other dairy products; lactose in breast milk is β-lactose, in the body can break down into galactose. Nutrients in breast milk not only meet the needs of children’s physical growth, or children’s brain development essential “raw material” for children’s intellectual development and lay a good material foundation. So people say
