Good and effective visual stimuli can enable the baby to more clearly and accurately perceive, accept, process external information, and form more visual memories in the cerebral cortex, thereby promoting brain development and improving intelligence levels. Therefore, during the baby's growth, vision development is a crucial link, and adequate nutrition is the material basis for vision development.
One of the nutrients: DHA
Among the retinal photoreceptors, DHA is the most abundant long chain polyunsaturated fatty acid, accounting for 50% of the total retinal phospholipids. Babies cannot synthesize DHA themselves and can only rely on dietary supplements. Studies have shown that foods such as deep-sea fishes and seaweeds are rich in DHA, while other foods have little or no DHA. Infants will use DHA primarily through breastmilk or formula milk.
The second nutrient: Vitamin A
Vitamin A plays a very important role in maintaining the normal vision of the human body, especially the ability to observe under low light. Because it is an important raw material for the synthesis of rhodopsin, and rhodopsin is a photosensitive material, present in the retina. Baby daily supplements can be added vitamin A, such as carrots, animal liver and so on. It should be noted that vitamin A supplementation is not anxious. Once it is oversupplyed, it can easily cause vitamin A toxicity.
Nutrients III: Taurine
There is a lot of taurine in the retina, which can improve the visual function and promote the development of the retina. 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. At this point, it is necessary to supplement taurine as soon as possible. The content of taurine in the following foods can be used as reference (milligrams per 100 grams of food): scallop 827, mussel 655, squid 356, tuna 39, black chicken 169, chicken 18, lean pork 61, beef 43.
Four nutrients: antioxidant nutrients
If the eyes are sensitive to light, they are prone to oxidation problems. At this time, some antioxidants, such as vitamin C, vitamin E, and lutein, can be supplemented in a timely manner. Vitamin C is derived from vegetables and fruits, among which dark green vegetables are particularly rich in vitamin C. Vitamin E comes from vegetable oils, dark green vegetables, wheat germ, and so on. Lutein belongs to the class of β-carotene and has significant preventive and ameliorative effects on eye diseases caused by retinitis pigmentosa, macular degeneration, and cataracts that increase with age. Lutein cannot be synthesized by the body itself. At present, there is no authoritative nutrition institution to propose recommended intake of lutein. In fact, the supplement of lutein is very simple and the cost is not high, so long as there are more choices of dark green vegetables, such as spinach and kale.
