With the rapid development of relief in our country, nutrition during pregnancy is getting more and more attention. It is both related to the health of the mother and beneficial to the fetal development. If the pregnant woman is malnourished can lead to fetal growth restriction, stunted development, or in serious cases, fetal malformation or fetal death in the womb. In general, pregnant women should diversify their diet, correct partiality, eat more meat, eggs, soy products and fresh vegetables and fruits (including nuts, such as walnuts, peanuts, etc.), and eat less spicy and stimulating food. Pre-conception preparation Three months before conception, take small doses of folic acid by mouth once a day. Because the human body cannot synthesize folic acid and mainly relies on food supply, and the need increases during pregnancy, additional supplementation is often needed in the first 3 months of pregnancy. Folic acid deficiency in early pregnancy can predispose the fetus to neural tube defects malformations. Main diet during pregnancy The daily calorie intake during pregnancy is between 2000-2250 kcal, which, according to the Chinese diet, is equivalent to at least half a catty of rice, 3 taels of meat (pork, beef, chicken or fish), 2 eggs plus a moderate amount of soy products, fresh vegetables and fruits per day. To avoid boredom with a certain food, try to eat alternately, eggs can be boiled or fried, in which case it is easy to stick to and ensure adequate nutrition. It should also be added that animal offal, mutton and rabbit are rich in nutrients, but due to folk customs and personal preferences, many pregnant women rarely eat animal offal, mutton and rabbit do not eat at all, in fact, they can eat. For fruits, what is available in the market to eat, do not have to deliberately buy expensive, rare high-grade fruit, so perhaps more practical and effective. Trace elements that need special supplementation during pregnancy 1, early pregnancy 3 months: mainly supplement folic acid and zinc, etc. At present, there are many kinds of trace element preparations specially prepared for pregnant women, which can be purchased according to the actual local situation. 2.Mid and late pregnancy: mainly supplement iron and calcium, and drink milk and milk products every day. After the middle of pregnancy, pregnant women have to consume up to 1000g of calcium and 28mg of iron per day, which must be specially supplemented. Since nowadays all attach importance to regular maternity checkups during pregnancy, if the mother-to-be still does not understand or is not sure, consult more with her doctor. If a careful mother-to-be wants to calculate the calories of her diet by herself, I provide an approximate calorie table, it may be worth calculating (rough reference). For every 50g, 5kcal for green vegetables, 15kcal for fruits (on average), 250kcal for dried fruits, 170kcal for rice, 175kcal for noodles, 66.5kcal for pork, 68kcal for beef, 60kcal for chicken, 77.5kcal for eggs, 30kcal for milk, 61.5kcal for grass carp and 41kcal for carp.
