Early pregnancy symptoms (7th week) Principles of nutritional needs of pregnant mothers

Early pregnancy symptoms In the 7th week, pregnant mothers should consume brain-building foods: The diet of pregnant mothers is closely related to the brain-building of the fetus. Modern nutritionists point out that the mother\’s diet during pregnancy is very important, as it directly affects the growth and development of the fetus, especially the development of the brain. There are two peaks of brain development during the fetal period, the first is within 3 to 4 months of pregnancy, and the second is from 7 months to full term. The brain is 50% to 60% fat, and most of it is unsaturated fat. Unsaturated fats mainly come from plant foods. Foods rich in vegetable fat include: millet, corn, soba noodles, sesame seeds, peanut kernels, walnut kernels, sweet potatoes, potatoes, various melon seeds, soybeans and their products, etc. The main component of the fat contained in walnuts is linoleic acid glycerol, which is a necessary nutrient for the development of fetal brain and visual functions. The trace elements zinc and manganese are important components of the pituitary gland. The normal intake of linolenic acid should start 3 months before pregnancy. If the pregnant mother does not have enough supply, the fetus will not be able to form a healthy brain, and once the nervous system is formed, it can no longer be repaired, which will lead to attention deficits in the child as an adult. The probability of hyperactivity disorder, impulsivity, anxiety, easy temper, poor sleep, poor memory and mental disorders is 6 times higher than that of ordinary people. Early Pregnancy Symptoms Pregnant mothers should eat enough calories in the 7th week: Due to the large amount of fat storage and the formation of new fetal tissue, the calorie consumption of pregnant mothers is higher than that during non-pregnancy. Therefore, caloric needs increase after pregnancy and gradually increase as pregnancy continues. It is extremely important to ensure the caloric supply of pregnant mothers. If the caloric supply is insufficient during pregnancy, the glycogen and fat stored in the mother\’s body will be used, and the pregnant mother will become thin and lack of energy. Dry skin, degeneration of skeletal muscles, slow pulse, lowered body temperature, weakened resistance, etc. According to research, the dietary caloric intake of pregnant mothers directly affects the growth and development of the fetus. Low intake can lead to low birth weight of the fetus. Therefore, pregnant mothers should consume sufficient calories and keep blood sugar at normal levels. Because glucose is necessary for fetal metabolism and is mostly used for fetal respiration. When the fetus consumes more maternal glucose, the mother has to supply it with oxidized fat and protein. When a pregnant mother does not consume enough sugar, consumes fat too quickly, and suffers from incomplete oxidation, ketoacidosis is very likely to occur. Pregnant mothers suffering from ketosis will have low blood sugar and high blood ketone bodies. Maternal hypoxia will lead to fetal hypoxia, which will have adverse effects on the fetal brain and nervous system development. Calories mainly come from fat and sugar. Fats mainly come from animal oils and vegetable oils. The caloric requirements of pregnant mothers should increase with the increase in basal metabolism during pregnancy, the growth and development of the fetus and placenta, the increase in maternal related tissues, and the increase in body weight. In early pregnancy, the increase in basal metabolism is not obvious, the embryo develops slowly, and the mother\’s body weight and breast development change very little. Therefore, the caloric intake only needs to be slightly increased than when not pregnant to meet the needs. Pregnant women need 400 to 500 grams of sugar every day. It is best to adjust the daily caloric supply according to the increase in weight. The weight should increase by about 12.5 grams during the entire pregnancy, and the weight should increase by about 12.5 grams per week in the second and third trimesters.The weight should be 0.3~0.5 dry grams.
