As a special group, pregnant women should not only pay attention to strengthening nutrition and eating nutritious food in moderation, but also pay great attention to dietary structure, cooking, food hygiene and food selection. During pregnancy, the baby's various organs continue to develop and need adequate nutrition supply. If you don't pay attention to balanced nutrition during pregnancy, not only will the fetus be stunted, but the mother will be weaker after delivery. To increase nutrition is not to eat more, but to pay attention to balanced nutrition in food.
1, not suitable for long-term high-fat diet.
During pregnancy, pregnant women need to increase their intake of fat appropriately, but if pregnant women eat a high-fat diet for a long time, it is bound to increase the risk of fetal reproductive system cancer. Eating high-fat foods for a long time will increase the concentration of cholic acid and neutral cholesterol in the large intestine. At the same time, high-fat foods can increase the synthesis of prolactin and promote the occurrence of breast cancer, which is not conducive to maternal and infant health.
2. Excessive intake of high protein is not advisable.
According to medical research, the insufficient supply of protein makes pregnant women weak, the fetus grows slowly, the postpartum recovery is slow, and the milk meter secretion is scarce. Therefore, the daily protein requirement of pregnant women should reach 90-100g. However, a long-term high-protein diet during pregnancy will affect the appetite of pregnant women, increase the burden on the gastrointestinal tract, and easily cause bloating, loss of appetite, dizziness, fatigue and other phenomena.
3, should not be high sugar diet.
Pregnant women with high blood sugar are prone to give birth to overweight fetuses, and also easily lead to fetal congenital malformation and toxemia of pregnancy. A large number of medical studies show that eating too much sugar will weaken the immunity of the human body, reduce the disease resistance of pregnant women, and make them susceptible to germs and viruses, which is not conducive to eugenics.
4, unfavorable long-term high calcium diet.
Pregnant women blindly eat a high-calcium diet, drink a lot of milk, and take calcium tablets and vitamin D, which is harmful to the fetus. Excessive calcium supplementation in pregnant women may lead to hypercalcemia in the fetus. After birth, the fontanel will be closed too early, and the jawbone will be widened and protruding, which is not conducive to healthy growth and development. Generally speaking, the daily calcium requirement of pregnant women in the first trimester is 800 mg, and it can be increased to 1 100 mg in the later trimester, which does not need special supplement, as long as it is taken reasonably from daily foods such as fish, meat and eggs.
5, should not be too salty.
Modern medical research believes that there is a certain relationship between salt consumption and the incidence of hypertension. Excessive salt consumption in pregnant women can easily lead to pregnancy-induced hypertension syndrome. For health care during pregnancy, experts suggest that the daily salt intake should be about 6 grams.
6, it is not appropriate to take warm supplements.
During pregnancy, if pregnant women often take warm tonics and supplements, such as ginseng, velvet antler, deer fetal glue, antler glue, longan, litchi, walnut meat, etc., it is bound to lead to hyperactivity of yang due to yin deficiency, disorder of qi stagnation, excess of qi and yin consumption, blood heat rash, aggravation of morning sickness, edema, hypertension, constipation and other symptoms, and even miscarriage or stillbirth.
