Protein? When you are 4-6 months pregnant, you should eat 15g protein more than usual every day, and 25g more when you are 7-9 months pregnant. High-quality protein mainly comes from animals, such as all kinds of meat, milk, eggs, fish, especially milk.
The main function of sugar is to provide heat. Most of the staple food eaten by pregnant women is starch, and the total daily staple food in the middle and late pregnancy is about 8 Liang 1 kg, which is enough.
Trace elements? Include many things, but almost all trace elements except iron can be obtained through normal food, such as calcium, zinc and iodine. However, the supply of iron is difficult to be completely supplemented from the diet, so iron can still be supplemented orally if conditions permit. As for related foods, milk is a rich source of calcium, and pregnant women are encouraged to drink it; Animal proteins (liver, meat and eggs) are rich in iron, which is more easily absorbed than iron in vegetables.
Most vitamins can be obtained from food, especially fresh fruits and vegetables, but the demand for folic acid is obviously increasing, which is related to fetal neural tube malformation, so it is recommended to take folic acid orally in the first three months of pregnancy.
So what should you pay attention to during pregnancy?
1. First of all, we must grasp several principles.
The biggest principle in diet should be omnivore, and the technical term is to pay attention to diet balance. The doctor said that eating fish is good and can supplement high-quality protein, so I will eat fish; The doctor says it is good to eat fresh vegetables, which can supplement vitamins and trace elements. For pregnant women with gestational diabetes, it is beneficial to do appropriate outdoor activities every day. Don't think gestational diabetes is far away from you. According to the current diagnostic criteria, the incidence rate is about 20%, that is, one fifth of the people. Moreover, even if you are not gestational diabetes, your insulin function during pregnancy is affected, and you have a tendency to have high blood sugar. It is also helpful to control diet, eat less and eat more meals, and exercise moderately. If you are thin during pregnancy, you will gain more weight during pregnancy. According to the figure of China people, women of childbearing age are still obese. This obesity means that the body mass index is greater than 26, that is, the weight divided by the square of the height, and the unit is kg/m2. In this way, the height is 1.65m and the weight can reach 70kg. Most young women in China can meet this standard. Moreover, if the body mass index is less than 19.8, it is considered to be underweight, that is to say, people with a height of 1.65 meters weigh less than 100 kg, so such women should gain more weight during pregnancy. For most people whose body mass index is between 65438 and 09.8-26, it is better to control the total weight gain during pregnancy between 23 kg and 32 kg, and the value is easy to remember. However, the weekly weight gain in the first trimester was less, and it increased by about1-2 kg throughout the first trimester. In the second and third trimester of pregnancy, she gained about 6 Liang to 1 kg per week.
