How to eat diet to protect baby's eyesight?
Lutein acts on retina, β -carotene prevents night blindness, zeaxanthin is more resistant to strong light, anthocyanin eliminates eye fatigue, DHA is an important component of retina, and zinc improves the regulation of light.
Lutein is an important antioxidant, which can scavenge free radicals and enhance immune function. Its absorption spectrum contains near blue-violet light, which can help the retina of the eye resist ultraviolet rays, improve fundus circulation, promote nutrient supply and maintain the function of retinal cells. Food source: mango, orange, corn, carrot, spinach, leek, Chinese cabbage and pumpkin.
β -carotene has antioxidant effect and can scavenge free radicals; It can be converted into vitamin A in the body, also known as provitamin A; Vitamin A can be converted into rhodopsin, which can maintain the circulation of dark vision sensitive substances and prevent night blindness and dry eye. Food sources: spinach, carrots, pumpkins, mangoes, sweet potatoes, lettuce, papaya and broccoli.
Zeaxanthin protects cone cells and epithelial cells; Maintain the health of retina and macula, enhance the ability of macula to resist harmful substances and light damage, and prevent cataracts. Food source: corn, pepper, cantaloupe, mango, medlar, peach and egg yolk.
Anthocyanin can accelerate fundus circulation, enhance substance metabolism and exchange, and then improve macular recovery time and night vision ability; It can promote the regeneration of rhodopsin in retinal rod cells and scavenge free radicals in vivo. Food source: purple potato, grape, blood orange, blueberry, blueberry, cherry, mulberry and purple cabbage.
DHA can improve retinal reflex function, prevent visual impairment from affecting the formation of brain and retinal tissue structure and the improvement of optic nerve function. Food sources: deep-sea fish, nuts, shrimps, crabs and shellfish, and vegetable oil. Zinc participates in the metabolism and transportation of vitamin A, maintains the normal tissue state of retinal pigment epithelium, and has a certain regulatory effect on light. Food sources: oysters, animal meat, liver, beans and nuts.
