From the first trimester of pregnancy, the baby's brain has entered the early development, the third trimester is the period of rapid development of the baby's brain, so throughout the pregnancy, expectant mothers should pay attention to nutrition, eat more to promote the baby's brain development food. Early Pregnancy (1-3 Months): Baby Brain Enters Early Developmental Stage At this stage, although the expectant mother does not feel very obvious, the fetus's brain has begun to develop. In the second half of the first month, the brain and spinal cord enter the early stages of development; in the second month, there are 100,000 neurons produced every minute in the brain. To know that there are a total of about 100 billion neurons in an adult brain, the speed is very high. amazing. The first month was also an important period for the formation of neural tube division. The nervous system began to function from about the 2nd month and even produced a weak brain wave. Early pregnancy nutrition advice Mothers are smarter to eat baby like this 1. Daily supplementation of folic acid 400 micrograms. In order to avoid neonatal neural tube malformation and insufficient brain development, it is necessary to start supplementing folic acid daily from the beginning of pregnancy until the entire pregnancy. Eat more foods rich in folic acid, such as animal liver, kidneys, eggs, beans, green leafy vegetables such as spinach. However, it is worth noting that animal livers are rich in vitamin A, and excessive intake of vitamin A may be detrimental to the fetus, so each time should not be excessive (25-50 grams is good). 2. Eat more foods rich in vitamin B6, vitamin B12, can ease the pregnancy response. During this period, expectant mothers began to have gestational reactions. Pregnancy reactions lead to reduced diets, which may result in deficiency of micronutrients such as folic acid, zinc, and iodine. Severe vomiting may also lead to loss of water and electrolytes and disorders in the body, resulting in excessive decomposition of body fat. Excessive metabolism of ketone bodies and ketoacidosis, which will affect the development of the fetal nervous system. It is recommended to eat more animal livers, fruits, nuts and coarse grains rich in vitamin B6 and vitamin B12. When necessary, under the guidance of a doctor, oral supplement B-complex vitamin preparations. 3. Pay attention to the intake of staple food grains (mainly carbohydrates). Glucose can provide energy to the brain, and carbohydrates are the main suppliers of glucose, so despite the bad appetite in early pregnancy, we must ensure that the daily intake of not less than 200 grams of staple foods, as well as the right amount of potatoes and fruits. Mid-pregnancy (4-6 months): The basic structure of the baby’s brain At this stage, the brain still maintained the early speed development. The left and right cerebral hemispheres grew rapidly and the connections between neurons became more complex. At the sixth month, all the neurons were generated and the surface of the brain began to fold. Already close to the brain structure of adults. Second trimester nutritional advice 1. The basic menu to ensure brain development: eat 2-3 times a week fish, one of which is as much as possible marine fish; one egg per day; seafood at least once a week; 250 milliliters of milk per day or the same amount of dairy products. In addition to providing high-quality protein, fish can also provide Omega-3 polyunsaturated fatty acids (DHA and EPA) that are essential for fetal brain and retina function development. Eggs, especially egg yolks, are a good source of lecithin, vitamin A and vitamin B2. Seafood can prevent inadequate intake of iodine during pregnancy and affect fetal brain development. Dairy products supplement calcium for mothers and baby babies. 2. Eat more soy, nuts (walnuts, almonds, etc.) and deep-sea fish and shrimp, to provide the baby with the fat needed for brain development. Fat, especially lecithin and polyunsaturated fatty acids, play an important role in promoting the development of brain cells and the formation of nerve myelin. Appropriate increases in the intake of these foods can be made from the second trimester. Normal edible oils such as sunflower oil, soybean oil, and olive oil contain polyunsaturated fatty acids, but the total intake should be controlled so as to avoid excessive dietary energy and cause maternal and child obesity. Late pregnancy (7-9 months): Brain development begins to accelerate Experts refer to the last 3 months of pregnancy and the first year after birth as the "accelerating period of brain development." At this stage, the brain gains 1.7 grams per day, which means that the weight gain is about 1 milligram per minute. The development of the brain is more sophisticated and sophisticated. In the end of the fetus, brain waves show that the baby has even the sleep and awakening phases. Late pregnancy nutrition advice The basic structure of the baby’s brain during the second trimester cannot be formed, but the nutritional intake at this stage is neglected. The “basic menu†that promotes brain development during the second trimester must continue to be guaranteed. Fish, poultry, eggs, lean meat The intake of seafood may increase in moderation. Tips: mothers do not eat too much fish, especially oversized fish Although fish is beneficial, it should not eat too much. The survey data showed that there is widespread contamination of heavy metals (tribute, cadmium, and lead) in marine fish. You can choose small-sized sea fish and eat less fish head, skin and internal organs. The heavy metal content in these parts is higher than that of fish. You can eat it 1-2 times a week, and you need to use vegetables when you eat.
