It is best for pregnant women not to eat crab yellow tofu. Although crab meat is delicious, it is a cold food and has the effect of promoting blood circulation and removing blood stasis, which is harmful to pregnant women. And crab claws even have the function of abortion. After 1 1 week of pregnancy, the fetus begins to develop rapidly and needs more and more nutrition. At this time, expectant mothers need to eat more high-quality food, but the diet should be light, which is conducive to absorption, and more foods high in protein should be supplemented.

Dietary considerations in the first trimester of pregnancy:

In the early pregnancy, pregnant women need to pay great attention to diet, and it is best to take more nutrients beneficial to embryo development, such as high-quality protein, fatty acids, heat energy, multivitamins and mineral elements. Spicy and irritating food, fried food and some foods that are easy to get angry are best eaten less or not.

1, intake of protein, this period is a period when protein is stored relatively much in the body, in which the fetus remains about 170g, and the mother remains about 375g, which requires pregnant women to increase their dietary protein supply by 25g compared with non-pregnant women, and should consume more animal food and soybean food.

2, essential fatty acids, this period is the peak of fetal brain cell appreciation, it is necessary to provide enough essential fatty acids such as arachidonic acid to meet the needs of brain development, eating more marine fish can be conducive to the supply of DHA.

3. Calcium and iron intake. More than half of the calcium in the fetus is stored in the third trimester. Pregnant women should take 1500mg of calcium every day and supplement appropriate amount of vitamin D.. Fetal liver stores iron at a rate of 5mg per day during this period until it reaches 300-400mg at birth. Pregnant women should consume 28mg of iron per day, and should consume more hemoglobin-based iron from animal foods.

4. Pregnant women should regularly consume milk, fish and bean products. It is best to fry small fish or eat them with vinegar crisp and drink sparerib soup. Shrimp skin is rich in calcium, and a little can be added to the soup; The liver and blood of animals have high iron content and high utilization rate, so they should be used frequently.

5, vitamins. Adequate water-soluble vitamins, especially thiamine, are needed in the third trimester of pregnancy. If it is lacking, it will easily cause vomiting and burnout, and the uterine contraction will be weak during delivery, which will delay the labor process.

6. Heat energy, the supply of which is the same as that in the second trimester, does not need to be supplemented too much, especially in the last trimester 1 month. The intake of saturated fat and carbohydrates should be appropriately restricted to avoid the fetus being too large and affecting the smooth delivery.
