It is not too late to eat these foods during pregnancy.

In different pregnancy periods, the development of the fetus is not the same, and the nutrition needed is also different. Therefore, expectant mothers should reasonably arrange their own diet according to different stages of pregnancy. So how to eat before pregnancy is scientific and reasonable?

Different dietary priorities during pregnancy

1, early pregnancy:

(1)Fetal development features:

In the early stages of pregnancy, the fertilized eggs divide and divide to form the various organs. At this point, the embryos are still small and grow slowly. Therefore, the demand for various nutrients is basically the same as or slightly higher than that before pregnancy.

(2) Dietary points:

1) Light diet and palatability: Mainly include fresh vegetables and fruits, soy products, fish, poultry, eggs, and various cereal products;

2) Eat small meals: In order to ensure food intake, ensure daily intake of 150 grams of carbohydrates, about 200 grams of cereals;

3) Increase the intake of B vitamins: In early pregnancy, many mothers will experience nausea, vomiting and other pregnancy reactions, there is no appetite, so, in the early stages of pregnancy can be appropriately increased intake of B vitamins to reduce the incidence of reduced pregnancy . You can eat chicken, fish, eggs, beans and other VB-rich foods, you can also eat complex vitamin supplements during pregnancy.

4) Supplement folic acid: 400 micrograms should be added daily until the entire pregnancy.

2, during the second trimester:

(1)Fetal development features:

After entering the second trimester, the early pregnancy response usually disappears. At this time, the growth and development of the fetus is accelerated, and the need for various nutrients is increased, especially in the third trimester. Therefore, attention should be paid to the supplementation of the following nutrients.

(2) Dietary points:

1) Properly increase protein intake:

Since the fetus's muscles and bones will develop rapidly at this stage, expectant mothers should consume 50 to 100 grams of food rich in high-quality protein such as fish, eggs, milk, lean meat, soybeans, and soy products. Among them, the preferred animal food is fish. Eat 2 or 3 times a week fish can also get polyunsaturated fatty acids.

Eggs, especially egg yolks, are a good source of lecithin, vitamin A and B2, and pregnant women should ingest one egg per day.

2) Appropriately increase milk intake:

The Chinese Nutrition Society recommends daily intake of 1,000 mg of calcium during the second trimester.

Therefore, starting from the middle of pregnancy, drink at least 300 ml of milk daily, supplement 300 mg of calcium, or drink 500 ml of low-fat milk daily to meet the needs of calcium.

3) Eat iron-rich foods:

In the second trimester, blood volume increases rapidly, red blood cells increase relatively slowly, and the incidence of anemia is high. The iron reserve in the first 6 months of the baby also comes from embryonic iron stores, so iron intake should be increased from the second trimester.

Iron-rich foods include animal liver and blood, lean meat, black fungus, etc., and animal-derived iron has a high absorption and utilization rate.

Increase the intake of vegetables and fruits rich in vitamin C, can promote the absorption of iron.

Dr Su Shiping said:

Expectant mothers should appropriately adjust the diet structure according to the different development and growth stages of the fetus, so that the nutrition is rich and reasonable, and do not blindly tonic, otherwise it will not only lead to excess nutrition, but also increase the chance of complications during pregnancy.
