Although spinach is rich in iron, it also contains a lot of oxalic acid. Oxalic acid combines with calcium in human body to form calcium oxalate. If pregnant women eat spinach in large quantities, calcium in the body will be rapidly lost, leading to calcium deficiency. The fetus itself needs a lot of calcium during its growth. If calcium is lost in pregnant women, the growth of the fetus will be affected. It seems that pregnancy really needs to be careful.

In addition, when spinach is eaten, if it is eaten with other foods at the same time, adverse chemical reactions may occur. For example, eating spinach and tofu together may induce stones. The health of pregnant women during pregnancy is very important. If eating a certain food is potentially harmful, I would rather not eat it than take chances.

In life, before eating spinach, blanch it with hot water, and most of the oxalic acid will be removed. Because oxalic acid is soluble in water, vitamins and iron in spinach can be absorbed by human body. For the health of pregnant women and babies, they should be eaten in small amounts, or they can be replaced by other iron-containing foods or vegetables.

Pay attention to the diet in the second trimester:

1, the diet should be rich in calcium.

Calcium is an important component to form bones and teeth, help muscle contraction and maintain blood function, and it needs to be taken in large quantities in the second trimester. Sardines and dried fish are important sources of calcium, but choose foods with less salt. Dairy products, green vegetables, eggs, almonds and sesame seeds are all rich in calcium. High calcium food can improve the absorption rate if it is eaten with beef, pork and chicken.

2. Adequate iron intake

Iron intake can prevent anemia. Foods rich in iron include red meat and animal liver. If iron food is taken together with vitamin C, the absorption rate will be higher, because vitamin C can promote the body's absorption of iron. On the contrary, black tea, coffee and other drinks contain caffeine, which will hinder the absorption of iron in the body. Pregnant mommy can't drink these drinks before eating 1 hour.

Step 3 eat foods rich in cellulose

Eating more foods rich in cellulose can effectively prevent constipation, but it should be eaten in moderation to avoid affecting the absorption rate of calcium and iron. In order to get enough cellulose, pregnant women can replace white rice with miscellaneous grains rice, replace broth or chicken soup with vegetable soup, and eat more fresh fruits and vegetables. Eat more than two kinds of vegetables every meal, and eat kelp, seaweed, kelp, seaweed and other foods with Shanghai algae every day.
