Water spinach is rich in calcium, but it also contains high oxalic acid, which is easy to form calcium oxalate precipitation and affect the absorption of calcium. So you can't eat more, especially in the third trimester.

Dietary considerations in the second trimester of pregnancy:

With the growth of the fetus, pregnant mommy's body needs to take in more protein and calcium. 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.
