In fact, this is a big misunderstanding! Proper improvement of diet and nutrition for pregnant women can enhance their physical fitness and promote fetal development. However, if there is overnutrition, the harm is not shallow.
During pregnancy, the blood content of the body increases, 20~30% more than usual. Relatively speaking, the burden in my heart will be heavier. Eating too much will increase the burden of digestion and have a certain impact on the heart. The result of blind pursuit of high nutrition is that the number of pregnant women with pregnancy-induced hypertension and diabetes increases, and the fetus is too large and stunted.
Pregnancy-induced hypertension syndrome is an important cause of maternal death in China. Dystocia and prolonged labor caused by "macrosomia" often lead to postpartum hemorrhage, which is another important cause of maternal death. Therefore, pregnant women should properly control their diet.
Pregnant women often feel hungry, which is a normal physiological reaction, but it is also an important reason why pregnant women are difficult to eat normally. It is suggested that pregnant women should include some low-energy and high-calorie foods, such as sweet potatoes and potatoes (except fried potatoes).
Now let's get back to the subject. Eat a lot every day during pregnancy. Where's all the meat?
After pregnancy, with the increase of pregnancy, the fetus develops rapidly, the pregnant woman's stomach is getting bigger and bigger, and her weight is also rising linearly. During the whole pregnancy, the weight of expectant mother and fetus increases almost simultaneously. Referring to the above composition chart of weight gain during pregnancy, under normal circumstances, the average weight gain during pregnancy is about 25 kg, and the baby weighs 6-7 kg at birth. The weight of placenta, amniotic fluid, uterus, blood, various body fluids, mammary glands, etc. It is about 10- 12 kg, and the meat growing on the mother (mother reserve) is 6-7 kg.
As we all know, if pregnant women want to develop their fetuses well, they must work harder on their diet, but this does not mean blind overeating. Although proper weight gain of pregnant women is one of the manifestations of healthy fetal development, it is unhealthy for pregnant women to gain too much or too little weight. Throughout pregnancy, the weight gain of pregnant women should be around 12kg. If you exceed this weight, it will not make the fetus "extra" fat, but will make the pregnant woman richer.
