Every expectant mother wants to make her baby smart and healthy, so the lovely mothers don't even consider the girl's figure and march to the food. There is a heroic sacrifice for the baby's birth and the heroic sacrifice. spirit. However, if you simply eat high-fat, high-protein foods is by no means a clever move, and even bring about unexpected consequences. When preparing for pregnancy, essential fatty acid preparations must be available. In 1993, the “Expert Meeting on Experts on Fats and Oils in Human Nutrition†put forward by the UN Food and Agriculture Organization and the World Health Organization pointed out that if you are blind to weight loss before pregnancy, you may suffer from pregnancy failure if you eat low-fat foods and lack body fat. Even if you become pregnant, you may endanger the development of the embryo. Therefore, preparation of fat is essential. But the preparation of fat is also very particular. Not all fats are good. As a mother, you should choose good fats for the baby that are good for your brain and physical development. For example, the fat of some sea fish and shrimp is currently We need to add, because the fat of marine fish contains mainly n-3 fatty acids; fat mothers such as corn oil, soybean oil and sunflower oil will eat less. Because these vegetable oils contain too much linoleic acid, it is an n-6 fatty acid, although it is also an essential fatty acid. However, at present, people use too much oil for cooking. At the same time, the proportion of linoleic acid contained in these oil components is too large. As a result, the n-6 fatty acids ingested by the human body are severely excessive, resulting in n-6 The phenomenon of severe imbalance of n-3 fatty acids affects the normal development of the brain and retina of the fetus and infant. The ratio recommended by the World Health Organization is 4:1 to 6:1. However, in fact, the ratio of DHA test centers to blood tests for pregnant women in Taiyuan, Beijing, and Guangzhou is seriously unbalanced to 25: 1 to 30:1 situation. Why should we emphasize the proportion of fatty acids? There are many expectant mothers who have symptoms of dysmenorrhea before pregnancy. They feel declining after pregnancy and often have numb hands and feet. After delivery, they also have memory loss, blurred vision, and even postpartum depression. These performances are inextricably linked to the vegetable oils we currently eat. Take corn oil as an example. It contains linoleic acid (n-6) up to 50%. In the corn oil meal plan in the United Kingdom in 1965, it was discovered that corn oil not only does not protect the heart and brain of heart patients. Instead, it also increased the death rate from heart disease. For women planning to become pregnant, excessive consumption of linoleic acid is more harm than good for itself and for the fetus. Because linoleic acid is metabolized into thromboxane in the body, it shrinks blood vessels and uterine smooth muscle, and sometimes even causes miscarriage. In addition to the choice of fat intake, the protein food is not as much as possible. What kind of influence does excessive intake of protein have? According to a report by the BBC (British Broadcasting Corporation), scientists in the United States have found that excessive levels of protein in the diet can reduce the success rate of female pregnancy. If the protein content of the diet is too high, the level of ammonium in the reproductive system will increase accordingly, affecting the normal imprinting of the H19 gene and fetal development, as well as increasing the chance of abortion. For women who want children, protein intake should not exceed 20% of total energy. Therefore, dietary nutrition before pregnancy is not what you eat. Protein supplementation can be based on labor intensity. For example, a pregnant woman who is very light and physically needs 80 grams of protein per day, whereas a woman who needs light energy needs 85 grams of protein. To sum up, pre-pregnancy nutrition preparation is not to say that the more everything is better, we should learn to identify the science, give our baby a nutritional future, but also give mothers a nutritional basis for their own.
