The diet in infancy is very important for a person's life. A reasonable and balanced nutritious diet will lay a solid foundation for a person's health throughout his life, and some unreasonable eating styles and habits will also lay hidden dangers for the health of adults.
Babies before four months have little saliva secretion, and basically do not have the function of secreting amylase. Adding starchy food too early will make food difficult to digest. Starch foods rich in carbohydrates accumulate in the stomach and ferment and inflate, which is easy to cause infantile diarrhea. Therefore, babies 4 months ago are generally breast-fed. It is particularly worth mentioning that colostrum within 1-12 days after delivery is extremely rich in nutrition, which is called "liquid gold" and contains precious natural antibiotics, growth factors and other necessary nutrients, among which immune components similar to gamma globulin can effectively inhibit the reproduction of harmful bacteria in the digestive tract.
The laxative effect of colostrum can also make the newborn excrete meconium as early as possible, which is beneficial to the normal digestion and absorption of nutrition by the digestive tract after birth. In some special cases, such as the mother's lack of milk or some infectious diseases, some diseases that are not conducive to breastfeeding, mothers can add or use milk and goat milk to feed.
After three or four months, because the iron content in the mother's milk has decreased, it is necessary to add broken egg yolk to the baby in time. After the baby is getting older, you can also eat steamed egg soup or drink some light soup made of pig blood and duck blood or liver paste made of pig liver, sheep liver and chicken liver to supplement the baby's demand for iron and prevent iron deficiency anemia.
After six months, the baby's deciduous teeth begin to sprout, and the capacity of the stomach is greatly increased, which can grow to about three times that of the newborn. At this time, adding complementary food is to prepare for weaning in the near future, and it is also the foundation for laying a lifelong intellectual development and healthy physique. At this time, babies can eat some soft solid foods, such as mashed vegetables, mashed meat or soft cakes, meatballs and the foods rich in iron, calcium and zinc mentioned above.
In addition, it is not easy to put a lot of sugar in the baby's diet. Although the first taste of human beings is sweetness, excessive intake of sugar will make the remaining calorie savings form puffiness, and importantly, it will consume a lot of calcium in the baby's body, which will affect the growth and development.
Some indigestion and emaciated babies can often eat rice oil. Professor Li Ruifen, a famous nutrition expert, actively suggested that rice oil be used as a supplementary food to supplement nutrition for thin babies. "Rice oil" is a fine and smooth layer of porridge skin floating on the surface of rice porridge, which is rich in carbohydrates, vitamins and unsaturated fatty acids. It is a nutritious food that babies can absorb easily and is effective in nourishing the gastrointestinal tract and improving the health of babies.
Infants should start with a single food, from less to more, from simple to complex, and the taste must be light. Excessive salt intake in infancy is also one of the causes of hypertension in adults. Within one year, the baby's brain develops very fast, which can reach 7%-75% of that of adults. This is an important period of brain function development, and a reasonable nutritious diet can help the baby to grow up into a smart baby in the first place. At this stage, we need to supplement enough high-quality protein, fat, B vitamins and vitamin C.
