What to eat during the third trimester
Entering the third trimester, the pregnant women's demand for nutrients also increases, because in addition to meeting the needs of fetal growth and development, pregnant women and fetuses also need to store some nutrients during this period. Therefore, pregnant women should increase the number of daily meals and food intake. Various nutrients and energy in the diet can meet the needs of pregnant women and fetuses. Here we take a look at the nutritional principles of the third trimester of pregnancy and some precautions.
The 5 nutrition principles of late pregnancy
Protein
From 28 weeks to 40 weeks of pregnancy, the body weight is increased from 1000 to 3000 grams, and the placenta, uterus, and breasts are also increased. It is necessary to increase protein intake, especially in the last 10 weeks of pregnancy, which is the most stored protein. A period.
2. Thermal energy
In addition to accelerated maternal metabolism, increased tissue, and rapid fetal growth, the fetus begins to store glycogen and fat in the skin and liver. Therefore, the fetus needs to increase calories.
3. Calcium and Vitamin D
Although expectant mothers need calcium supplementation during pregnancy, expectant mothers in late pregnancy have a marked increase in calcium requirements. At the same time, the calcification rate of the fetus's teeth and bones is also accelerating. Half of the calcium in the fetus is stored in the last two months of pregnancy. And calcium supplementation helps prevent pregnancy-induced hypertension in expectant mothers.
Vitamin D deficiency can cause a decrease in serum calcium, not only the mother's osteomalacia, but also fetal bone calcification disorders and tooth development defects, and even congenital rickets.
4. Iron
The fetal liver stores iron at a rate of 5 milligrams per day during the third trimester until it reaches 300-400 milligrams of iron at birth and expects mothers to consume 28 milligrams of iron per day.
5. Vitamins
Adequate water-soluble vitamins, especially vitamin B1, are needed during the third trimester. If it is absent, vomiting, burnout, and uterine contraction during delivery are likely to result in delays in labor.
When it comes to production, what should we pay attention to in order to make up for nutrition during this crucial period?
(1) Fresh vegetables and fruits are indispensable.
(2) Daily foods are all available to ensure that the intake of nutrients is complete.
(3) There is no need to add other supplements, a balanced diet can provide adequate nutrition.
(4) Spicy seasonings such as mustard, pepper, pepper, etc. should be eaten less.
(5) Wine, espresso, and cigarettes are harmful to the body and should be avoided as much as possible. Should not drink too much tea, tea contains a lot of caffeine, caffeine has an excite effect, drinking too much will stimulate increased fetal movement, and even endanger the growth and development of the fetus.
(6) Salted foods should be eaten less, such as salted eggs, salted fish, pickles, etc.; processed foods such as bacon, ham, sausage, fermented bean curd, etc. should also eat less or not eat.
(7) Ingestion of high-polysaccharide foods such as cakes, candies, etc., can easily lead to excessive weight and tooth damage, but also can reduce the alkalinity in the body, easily cause fatigue, weakness. A long-term acidic constitution also makes it easier for mothers to suffer from certain diseases, and more importantly, it affects normal and healthy growth and development of the fetus. It also affects the appetite of pregnant women and should be avoided as much as possible.
