As the saying goes: A pregnant woman must eat for two. Affected by this sentence, many pregnant women unconsciously increase their food intake, and the elderly at home will also urge them to take more supplements, for fear that they will not eat enough and starve their babies.
This concept is actually wrong. The nutrients needed for fetal development come from the mother\’s body. The nutrients eaten by pregnant women must be broken down into molecules, absorbed by the blood, and then enter the fetal blood through the placenta. It is not a good thing if the pregnant mother gains too much weight and the fetus is too large.
So, what should you eat during pregnancy?
First trimester (before 12 weeks of pregnancy)
In the first trimester, you can eat the same diet as before pregnancy. At this time, the embryo is still small and a normal diet is sufficient to meet the growth needs of the fetus.
Just follow the dietary principles of \”moderate, balanced and diverse\”. 
Second trimester (13-27 weeks of pregnancy)
Entering the second trimester. In most pregnant mothers, pregnancy symptoms disappear and their appetite begins to improve. This is also a good time for the fetus to grow rapidly. Remember to \”control your weight, eat less high-sugar and high-fat foods\” and increase your protein intake.
Third trimester (after 28 weeks of pregnancy)
As the due date approaches, many pregnant mothers are anxious, worried that their baby will not develop enough, and start eating and drinking excessively. This will increase the risk of \”giant baby\” and is detrimental to both the fetus and the pregnant mother.
Three principles of late pregnancy
1. Eat small meals and frequent meals: As the uterus gradually increases and compresses the stomach, it can easily cause indigestion. Therefore, eat small meals frequent and less greasy and indigestible food
2. Diet diversification: Supplement more high-quality protein, drink more milk, and have a daily protein intake of 85g, such as beans, eggs, milk, fish, etc.
3. Monitor the rate of weight growth: Weight grows very quickly in the third trimester, and you need to weigh yourself every day. If you grow too fast, you need to control it, especially staple foods such as rice, noodles, steamed buns and other carbohydrates, and fruits that contain a lot of sugar. Also eat less
Another important nutrient in late pregnancy is unsaturated fatty acids, such as walnuts, sesame, etc., which can promote the growth and development of the fetal brain and promote the development of the fetal retina
It is normal for weight gain during pregnancy to be around 20-25 pounds
How to grow a fetus without gaining weight?
For this issue, I believe it is the issue that pregnant mothers are most concerned about. 
First of all, every time you eat something, supply it to the fetus first, and then supply the excess to yourself. If you eat too much in one meal. The fetus does not need so much, and the excess nutrients are absorbed by yourself. So eat smaller meals more frequently.
Secondly, the placenta transports nutrients in one direction and will not transport the nutrients of the fetus to you.
In addition, reduce the intake of carbohydrates, fats and fruits, especially fruits, which are high in sugar, and increase the intake of high-quality protein. And take more walks after meals
