Breastmilk provides sufficient nutrition for optimal growth, development and health of the infant during the first 6 months of life. Exclusive breastfeeding of infants is the standard for growth and development because human milk provides the ideal amount of calories and protein needed for a healthy full-term infant. During the first 6 months of life, breastfed infants do not need any additional food or fluids. Healthy full-term infants of well-nourished mothers do not need vitamin or mineral supplements (except for vitamin D supplementation). The introduction of complementary foods after the child is about 6 months old requires additional supplementation and getting the child used to eating a variety of family foods. In particular, foods higher in iron and zinc should be introduced into the child’s diet, as iron and zinc needs increase as the amount of minerals in breast milk decreases. Breastmilk continues to provide critical and important nutrients. As large amounts of complementary foods are introduced into children’s diets, the intake of breast milk will gradually decrease. To meet the nutritional needs of the growing number of breastfed children, supplemental foods should be fed promptly, adequately, safely, and appropriately. Breast milk is the ideal food for infants and young children. The content and proportion of nutrients not only meet the needs of growth and development, but also are easily digested and absorbed, adapting to the underdeveloped digestive system of infants and young children. Breast milk is rich in DHA, while cow’s milk has low or no detectable DHA content, etc. Breast milk has natural advantages in three major nutrients: fat, protein and sugar. Fat 1. 98% of fat exists in the form of triglycerides and provides 50% of energy. 2.Fatty acids in breast milk are mainly in the form of sn-2 palmitic acid, accounting for 60-70%, relative to cow’s milk only 30-40%, which can avoid calcium soap generation to the greatest extent, reduce hard stools and promote calcium absorption. 3, breast milk is rich in DHA, which can better support normal eye and brain development. Protein 1. There is more whey protein than casein in breast milk, the ratio is about 60:40 in mature breast milk, but the ratio of whey to casein in cow’s milk is 18:82. 2. There is more whey protein than casein, and the clot formed in the stomach is small and soft, which is suitable for infants to digest and absorb. Lactose The lactose content in breast milk is much higher than cow’s milk, which has the characteristics of third-order absorption. 1.It is absorbed and used in the small intestine to provide energy. 2.It is broken down and utilized by flora in the colon, which facilitates the growth of bifidobacteria as well as lactobacilli. The intestinal flora metabolizes lactose and promotes the absorption of minerals by promoting the dissolution of certain minerals, lowering the ph value in the intestine and increasing the osmotic pressure in the intestine. With the modernization of our society, the current nutritional deficiency is transformed to overnutrition or nutritional imbalance. Currently more research is organic food. But, do you really understand organic? 1, organic is a product production and processing methods, organic products production process shall not use chemically synthesized pesticides, fertilizers, growth regulators, feed additives, and genetically engineered organisms and their products. 2, non-organic products may use excessive amounts of chemical pesticides, antibiotics, etc. during the production process, which can cause certain health risks, such as affecting the nervous system. The potential safety risks present in food can affect the health of adults, and the health of delicate babies can be even greater. The production of organic formulas needs to meet more stringent standards, from the farm to the cow to the factory, with layers of control that can ensure it is safer and healthier.
