Four nutrients affect the fetal vision First, alpha linolenic acid We often eat nuts such as walnuts, deep-sea fish such as grouper, salmon, tuna, or fish oil are all rich in alpha linolenic acid. In fact, supplementing cod liver oil is also a good way to brighten your eyes. There are similar alpha-linolenic acid capsules like cod liver oil. Here it is important to point out the importance of alpha linolenic acid for fetal eye development. Alpha-linolenic acid is an important component of brain cells and retinal cells. It can promote fetal and neonatal brain cell development, promote rhodopsin formation in the retina, increase fetal and neonatal intelligence and vision, and reduce fetal and neonatal neural tube. Malformations and incidence of various birth defects. Experiments abroad have also shown that alpha-linolenic acid can enhance fetal infant vision, and alpha-linolenic acid also affects the optic nerve. If the alpha linolenic acid intake is low, abnormalities of the retinal map may occur. If maternal or postnatal newborns lack alpha-linolenic acid, the content of DHA in the phospholipids of the newborn's retina will be reduced by half, and the brain gray matter will be reduced by 1/4, which will weaken the visual acuity of newborns, which will affect future vision. Recommendation: Since maternity is the main provider of fetal and infant nutrition, mothers during pregnancy and lactation should pay special attention to the intake of alpha linolenic acid. In addition to the normal diet, an additional 1000 mg of alpha linolenic acid is recommended daily. Second, vitamin A There are two types of foods rich in vitamin A: First, the original vitamin A, that is, various carotene, found in plant foods, such as green leafy vegetables, yellow vegetables and fruits, rich in spinach, wolfberry, Pea seedlings, red heart sweet potatoes, carrots, green peppers, squash, etc.; the other is vitamin A from animal foods, this type of vitamin A can be directly used by the body, mainly in animal liver, milk and dairy products (Unskimmed milk) and poultry eggs. Vitamin A is an important raw material for synthetic rhodopsin, and rhodopsin is a photosensitive material that is present in the retina. Vitamin A plays a very important role in maintaining the normal vision of the human body, especially the ability to observe under low light. In the absence of vitamin A, the ability of the eyes to feel weak light will decline, and objects cannot be seen clearly under low light. Fish contains rich vitamin A, but I do not recommend pregnant mothers to eat canned fish food, it is best to buy fresh fish for cooking, pregnant mothers eat at least once a week fish. In addition, pregnant mothers can choose cod liver oil if they worry about the pollution of deep-sea fish. In addition, I also recommend that mothers eat more foods rich in vitamin A, such as animal liver, egg yolk, milk, cod liver oil, carrots, apples and so on. Among them, vitamin A is the most common in chicken liver. It should be noted that vitamin A supplementation is not anxious. Once it is oversupplyed, it can easily cause vitamin A toxicity. Therefore, mothers can also choose to use vitamin A supplements for pregnant women. The fetus needs to store a certain amount of vitamin A in the liver. Therefore, our nutrition experts recommend daily intake of 1200 micrograms for pregnant women. In addition to the increase in intake of food from pregnant women, pregnant women also need to supplement 500 micrograms daily. Breast-feeding mothers also need to add supplements. Three, taurine Among all foods, fish and shellfish have the most abundant taurine content. Regular consumption of these foods can supplement taurine and stay healthy. At present, the per capita annual consumption of taurine in some major countries in the world is roughly: Japan 60g, the United States 50g, the United Kingdom 34g, Germany 32g, Canada 29g, France 26g, South Korea 19g, Indonesia 17g, Singapore 17g, and China is less than 0.2g. There is a large amount of taurine in the human retina, which can improve the visual function and promote the development of the retina. Taurine can also protect the retina, which facilitates the development of visual receptors and improves visual function. Studies have shown that the cornea of ​​the eye has the ability to repair itself, and taurine can strengthen the self-repairing ability of the cornea to fight eye diseases. It can be seen that taurine is also very important for preventing eye diseases and protecting eye health. Taurine is an amino acid that is ubiquitously present in various tissues of animals in free form. Taurine promotes the development of the central nervous system and promotes the proliferation, migration and differentiation of brain cells. When the content of taurine in the retina is reduced, the structure and function of the retina may be disordered, which is extremely detrimental to the development of vision. The synthesis of taurine in infants and the reabsorption of taurine by renal tubular cells are all poor. If there is no external supply, taurine deficiency may occur. Preterm infants lack the reserves of taurine and are more likely to lack. Nutritionists recommend taurine supplementation to the fetus and infant through the mother. It is very necessary for pregnant mothers and new mothers to supplement taurine as soon as possible. Recommendation: When mothers expect more taurine to be supplied to the fetus during pregnancy, the fetus can accumulate 6-8 mg of taurine per day four months after the pregnancy. The best daily supplement for pregnant women and mothers is 20mg. IV. Vitamin B Vitamin B1 is widely found in natural foods. It is rich in animal organs (liver, heart and kidney), meat, beans, peanuts, cereals, nuts and nuts. The content of fruits, vegetables, eggs, and milk is low. Animal viscera is rich in vitamin B2, especially in the liver. Other animal foods such as pork, eggs, eel and crab in aquatic products also contain more vitamin B2. Bacteria and algae foods in plant foods such as mushrooms, kelp, and seaweed contain more vitamin B2. Vitamin B1 and vitamin B2 are one of the sources of nutrition for the optic nerve. If vitamin B1 is insufficient, eyes can easily fatigue. If vitamin B2 is insufficient, it can cause keratitis. Recommendation: Pregnant mothers only need to eat 50 to 100 grams of these viscera each day to meet the needs of pregnant mothers a day of vitamin B2. In addition, do not eat too white and over-scouring the rice, cereals is the main source of vitamin B1, but due to the presence of vitamin B1 in bran and embryos, such as rice flour milling can cause a lot of vitamin B1 loss.
