Breastmilk is the ideal food for full-term infants up to 12 months of age. Breast milk is fresh, has the right temperature, is free of bacterial contamination, will have catabolic subject IgA, phagocytes, lactoferrin and iron-binding whey protein, inhibits the growth of Escherichia coli in the intestine, and contains a variety of essential and sulfur-containing amino acids. Cow’s milk contains excessive sodium, potassium and protein which increases the burden on the kidneys and is not suitable for infants. Infants under 12 months of age who are fed only whole milk are prone to blood loss in the intestinal tract. Milk containing low fat can cause energy deficiency. Soy formula is used to feed children with lactase deficiency or galactosemia and infants with milk allergy, but ginkgo with milk allergy may also be allergic to soy protein, so infants with milk allergy or absorption disorders are better off with a formula with protein hydrolysis.
