Modern medicine has proved that milk contains a variety of functional factors beneficial to eugenics, among which L-carnitine contained in milk is an energy substance for sperm maturation, which can increase the number and vitality of sperm and help maintain male reproductive health.
Vitamin K and vitamin A contained in milk are not only beneficial to the synthesis and secretion of sex hormones, but also can ensure the normal concentration and vitality of sperm. In addition, vitamin A is one of the elements of fetal development and children's growth, which contributes to good pregnancy, placental protection and normal early development. Vitamin B2 contained in milk can help pregnant women to effectively supplement vitamin B2 and avoid fetal skeletal malformation.
Vitamin E contained in milk can enhance ovarian function and prevent habitual abortion. Folic acid contained in milk can prevent fetal neural tube malformation and spina bifida, and avoid the birth of neural tube malformation, anencephaly and spina bifida.
Trace elements such as zinc and selenium contained in milk are conducive to maintaining the health of gonads, promoting the sound development of sexual organs and secondary sexual characteristics, making the number of male sperm normal and the menstruation of women normal, which is conducive to the sound development of pregnant fetuses without teratogenesis and normal growth.
In addition, milk is rich in minerals such as protein, fat, lactose, vitamins, calcium, iron and sodium, and is considered as an ideal food with balanced nutrition. Sticking to drinking milk is one of the important ways to fully supplement women's nutrition. More and more young couples begin to pay attention to how to give birth to a healthy baby scientifically, and know that during pregnancy and lactation, the mother is the only source of nutrition for the baby, and reasonable nutritional supplement is very important for pregnancy and eugenics.
The nutritional status of mother directly affects the health of fetus. Malnutrition or deficiency not only affects the health of pregnant women, but also has a close relationship with the differentiation and growth of fetal organs. In severe cases, it will even affect the development of fetal brain cells, which is not conducive to the intellectual development of the fetus. This requires mothers to improve their nutritional reserves before pregnancy, strengthen their nutritional intake during pregnancy and lactation, and reasonably supplement various nutrients. At present, the most ideal and economical way is to drink milk.
Of course, the emergence of milk and dairy products containing related substances in the market for the special needs of pregnant women is undoubtedly a sign that society attaches importance to prenatal and postnatal care and improves women's quality of life. In addition, milk can also prevent hypertension. Although hypertension is a common disease in middle-aged and elderly people. However, research shows that this disease can be prevented from the time when the fetus is in the mother's belly. If the baby's mother insists on drinking a certain amount of milk every day in the last three months of pregnancy, it can lower the child's blood pressure. If the blood pressure in childhood exceeds the normal standard, high blood pressure will often occur in adulthood. If you drink a glass of milk every day, you can lower the systolic blood pressure. Therefore, people call milk the natural enemy of hypertension.
Some developed countries attach great importance to and ensure the intake of milk by women and children. In Japan, from the beginning of female pregnancy, local government departments began to give free milk, which was distributed by special personnel. Send two bottles home every day until the child is 2 years old. The regulations of local government departments are slightly different, and the distribution cycle is even longer in some places.
In Canada, people even use the monthly tax-free benefits paid by the government to eligible applicants to help raise children under the age of 18, which is called "milk money". These countries generally attach importance to and strive to ensure children's demand for milk, and have developed good milk consumption habits. The role and contribution of milk to human health, women and children is still enormous.
