1st trimester Staple nutrient: Folic acid Role: Prevent fetal neural organ defects Folic acid supplementation can prevent anemia, premature birth and fetal malformations, which is especially important in the early stages of pregnancy, when fetal neural organ development is crucial. Pregnant mothers should always eat foods rich in folic acid, such as cereals like bread, noodles, white rice and flour, as well as beef liver, spinach, lobelia, asparagus, beans and apples, citrus and oranges. In addition to dietary supplements, you can also take oral folic acid tablets to ensure the daily requirement of folic acid. 2nd month of pregnancy Main nutrients: vitamin C, vitamin B6 Effects: Relieve gum bleeding, inhibit pregnancy vomiting In the 2nd month of pregnancy, some mothers-to-be may find their gums bleeding when they brush their teeth. At the same time, it can help improve the body’s resistance and prevent dental diseases. Vitamin C in life comes from fresh fruits and vegetables, for example, peppers, cauliflower, cabbage, tomatoes, cucumbers, spinach, lemons, strawberries, apples, etc. The above foods should not be cooked for too long to avoid large loss of vitamin C. For those mothers-to-be who suffer from pregnancy vomiting, vitamin B6 is the nemesis of pregnancy vomiting. Vitamin VB6 is highest in maltose, and 1-2 spoons of maltose a day can not only suppress pregnancy vomiting, but also energize pregnant women. Foods rich in vitamin B6 include bananas, potatoes, soybeans, carrots, walnuts, peanuts, spinach and other plant foods. Animal foods such as lean meat, chicken, eggs, fish, etc. are more abundant. The main nutrients in the third month of pregnancy: magnesium, vitamin A Role: promote the growth and development of the fetal baby Magnesium is not only vital to the health of the fetal muscles, but also helps the normal development of bones. Recent studies have shown that the amount of magnesium consumed in the first trimester is related to the height, weight and head circumference size of the newborn. Magnesium is readily found in salad oil, green leafy vegetables, nuts, soybeans, pumpkin, melon, sunflower seeds and whole grains. In addition, magnesium is good for the recovery of the uterine muscles of the mother-to-be. Vitamin A is needed throughout the development of the fetus, and it especially ensures the health of the fetal skin, gastrointestinal tract and lungs. During the first trimester, the fetus cannot store vitamin A on its own yet, so the pregnant mother must have an adequate supply. Sweet potatoes, pumpkins, spinach and mangoes all contain high amounts of VA. 4th trimester Staple nutrient: Zinc Role: Preventing fetal baby stunting This month the mother-to-be needs to increase her intake of zinc. If the mother-to-be is deficient in zinc, it will affect the growth of the fetal baby in the womb and will cause the fetal brain, heart, and other vital organs to develop poorly. Zinc deficiency can cause abnormal taste and smell, loss of appetite, poor digestion and absorption, and reduced immunity in pregnant mothers, which will inevitably result in delayed intrauterine development of the fetus. Zinc-rich foods include oysters, oysters, liver, portobello mushrooms, sesame seeds, red mussels, etc. Oysters are especially rich in zinc. Zinc supplementation should also be in moderation and should not exceed 45 mg of zinc in the diet daily. The 5th month of pregnancy The main nutrients: vitamin D, calcium Role: to promote the development of the fetal baby’s bones and teeth After the 5th month of pregnancy, the fetal baby’s bones and teeth grow especially fast, is a period of rapid calcification, the demand for calcium is simply a sharp increase. Therefore, from this month onwards, milk, maternal milk powder or yogurt is an essential calcium supplement drink for the mother-to-be every day. In addition, one should also eat more of the following foods that are easy to get calcium, such as, dried cheese, tofu, eggs or duck eggs, shrimp, fish, and seaweed. In addition, the mother-to-be should take calcium supplements daily. It is important to note that calcium supplements should be taken throughout the pregnancy. Of course, pure calcium supplementation is still not enough, vitamin D can promote the effective absorption of calcium, pregnant mothers should eat more fish and eggs, in addition, sun exposure can also create VD, pregnant mothers can be appropriate sun exposure, but first of all, we must do a good job of sun protection. The main nutrient in the sixth month of pregnancy: iron Role: to prevent iron deficiency anemia At this time, the nutritional needs of the mother-to-be and the fetal baby are increasing. Many mothers-to-be begin to show symptoms of anemia. Iron is one of the important elements in the composition of red blood cells, so it is especially important to pay attention to the intake of iron this month. In order to avoid iron deficiency anemia, mothers-to-be should pay attention to dietary preparation and consciously eat some iron-rich vegetables, animal liver, lean meat and eggs. You can also take 0.3-0.6 grams of ferrous sulfate orally every day starting from this month. The 7th month of pregnancy The main nutrient: “brain gold” Role: to ensure the normal development of the baby’s brain and retina DHA, EPA and lecithin, lecithin and other substances together, known as “brain gold”. “Brain gold” has a double significance for the mother-to-be in the first month of pregnancy. First of all, “brain gold” can prevent premature birth, prevent fetal growth retardation, and increase the weight of the baby at birth. Secondly, at this time, the fetal baby’s neurological system is gradually perfected, and the development of the whole body tissues, especially the brain cells, is significantly faster than that of the early pregnancy. The intake of sufficient “brain gold” can ensure the normal development of the baby’s brain and retina. In order to supplement the adequate amount of “brain gold”, pregnant mothers can alternatively eat some DHA-rich substances, such as walnuts, pine nuts, sunflower seeds, almonds, hazelnuts, peanuts and other nuts rich in natural linoleic acid, linolenic acid, in addition to sea fish, fish oil, etc.. These foods are rich in essential fatty acids needed for the development of brain cells of the fetal baby, and have a brain-boosting and educational effect. The 8th month of pregnancy The main nutrient: carbohydrates Role: to maintain the body’s caloric needs In the 8th trimester, the fetus begins to store glycogen and fat in the liver and subcutaneous. Insufficient carbohydrate intake at this time will result in protein deficiency or ketoacidosis, so the supply of calories should be ensured in the 8th trimester by increasing the intake of staple foods, such as rice and flour. Generally speaking, the mother-to-be needs to eat about 400g of cereals on average every day, which is important to ensure the supply of calories and save protein. In addition to rice and flour staples, add some coarse grains, such as millet, corn, oatmeal, etc. The main nutrient in the ninth month of pregnancy: dietary fiber Role: to prevent constipation and promote intestinal peristalsis Later in pregnancy, the gradually increasing fetal baby brings burden to the mother-to-be, who is prone to constipation. Due to constipation, internal and external hemorrhoids can occur. In order to relieve the pain caused by constipation, pregnant mothers should pay attention to the intake of sufficient amounts of dietary fiber to promote intestinal peristalsis. Whole wheat bread, celery, carrots, white potatoes, potatoes, bean sprouts, cauliflower and various other fresh vegetables and fruits are rich in dietary fiber. Pregnant mothers should also take appropriate outdoor exercise and develop the habit of regular daily bowel movements. In the 10th month of pregnancy, the main nutrient: thiamine (vitamin B1) Role: to avoid prolonged labor and delivery difficulties In the last month, it is necessary to supplement all kinds of vitamins and sufficient iron, calcium, adequate water-soluble vitamins, especially thiamine is the most important. If thiamine is not enough, it will cause vomiting, lethargy and lack of body, and may affect the contraction of the uterus during labor, prolonging labor and making delivery difficult. The content of thiamine is relatively high in sea fish.
