Calcium supplementation is needed before pregnancy
New medical research has found that expectant mothers are calcium deficient before pregnancy, so experts remind them to especially strengthen calcium supplementation. Calcium ion is the most abundant inorganic ion. Under normal circumstances, the total calcium content in the adult body is about 1200 mg. About 99% of it is concentrated in bones and teeth, and the remaining 1% often exists in extracellular fluid, blood and soft tissues in a free or combined ion state. Calcium is a major component that is indispensable and used in large amounts during fetal development. Pregnant women use a large amount of calcium. If the mother\’s reserves are insufficient, it will be difficult to meet the fetus\’s large needs, and the fetus will use the mother\’s calcium, which is detrimental to maternal health and fetal development. Therefore, women before pregnancy must consume 2 times more calcium than usual. Although the demand for calcium is not so important at the beginning of pregnancy, it is only for a short period of time. Calcium is stored in the human body for a long time. A large amount of calcium supplement before pregnancy provides favorable conditions for use in the second trimester.
Calcium deficiency in men will slow down sperm movement and reduce the activity of sperm acrosome protease, which will definitely affect pregnancy.
In order to give birth to a healthy baby, expectant parents should supplement calcium before pregnancy. While supplementing calcium, they should also supplement vitamin D, which is beneficial to the absorption and utilization of calcium. You should usually eat more calcium-rich foods, and milk and dairy products are the best, as they are not only rich in calcium, but also have high absorption rates. In addition, sesame seeds, sesame paste, egg yolks, beans, peanuts, and vegetables are also high in calcium. Small shrimps are particularly rich in calcium, and cereals also contain calcium. And pay attention to get more sun at ordinary times. If the symptoms of calcium deficiency are very obvious, calcium supplements should be supplemented under the guidance of a doctor.
Supplementing selenium before pregnancy
Women of childbearing age who are deficient in selenium may have difficulty conceiving; if pregnant women are deficient in selenium, miscarriage may occur. Selenium can lower blood pressure in pregnant women, eliminate edema, improve vascular symptoms, prevent and treat pregnancy-induced hypertension, and inhibit the malignant transformation of gynecological tumors. In addition, it can prevent fetal teratogenesis. Selenium deficiency in men of childbearing age will reduce the energy source required for sperm activity, reduce sperm motility, and be detrimental to conception.
Therefore, expectant parents must supplement selenium before pregnancy. It is recommended that 400 micrograms of dietary selenium per day be the maximum safe intake. In addition to eating more fruits and vegetables before pregnancy, in addition to iodized salt, you should eat more marine plants such as seaweed, kelp, and seaweed in your daily diet. It is recommended to consume iodine-rich foods at least once a week.
Zinc supplementation is essential before pregnancy
Zinc is an important component of various enzymes necessary for a series of biochemical reactions in the human body, has a great impact on the metabolic activities of the human body. Zinc deficiency can lead to loss of taste and appetite, reduce the intake of nutrients, and affect growth and development. Zinc deficiency in pregnant women will affect the fetus, causing growth retardation, short stature, and even fetal malformations.
Zinc plays an important role in women’s pregnancy and fetal growth, so zinc should be supplemented when preparing for pregnancy. my country stipulates that pregnant women should provide 20 mg of zinc per day.
Modern medicine believes that zinc is directly and extensively involved in many aspects of male reproductive physiological processes, maintaining and improving sexual function, improving sperm quality, participating in the synthesis of testosterone, \”replenishing the seminiferous epithelium and sperm\” \”vitality\”; \”participates in the synthesis of any protein in the human body\”. According to numerous clinical experiments by medical scientists, the zinc content in normal male semen must maintain a healthy standard of 15 to 30 ml/100 ml. If it is lower than this standard limit, it means zinc deficiency or zinc loss, resulting in zinc deficiency. disease.
Scientific research shows that male zinc deficiency may be a cause of male infertility. The zinc content in normal human plasma is 0.6 to 1.33 micrograms/ml. The zinc content in semen is a hundred times higher than that in plasma. Zinc is directly involved in the glycolysis and oxidation processes in sperm, and is important for maintaining the integrity and permeability of sperm cell membranes and maintaining sperm vitality. If men are deficient in zinc, testosterone and dihydrotestosterone (androgens) will be reduced, which is not conducive to sperm production. Zinc deficiency can easily lead to unhealed prostatitis and epididymitis, which can cause male infertility. Therefore, when the wife is preparing to become pregnant, the husband must not be deficient in zinc. Therefore, eat more foods rich in zinc, such as pork liver, egg yolks, pork, peanuts, walnuts, apples, etc. my country\’s zinc supply stipulates that adults are 15 mg per day. If each person eats 120 mg of animal food per day, they can get the zinc they need.
Iodine supplementation is necessary before pregnancy
Although the iodine content is extremely low, it is indispensable for the development of various systems, especially the nervous system. Pregnant women can eliminate iodine deficiency. In addition to causing fetal brain development disorders, it can also cause obvious mental retardation and psychomotor disorders after birth. Supplement 175 mg of iodine every day. Foods rich in iodine include kelp, seaweed, and iodized salt.
