From the time a baby is born until the age of six, it is the golden age of vision development.But you know what?A proper diet can also protect children's eyes.
1. Foods rich in vitamin A, which is closely related to normal vision.If vitamin A is insufficient, the regeneration of rhodopsin is slow, and incomplete, the dark adaptation time is extended, and serious night blindness is caused.If dietary vitamin A continues to be deficient or insufficient, dry eye disease may occur. This disease can develop into keratomalacia and corneal ulceration. Corneal wrinkles and Pitt's plaques may also occur.The best food sources of vitamin A are various animal livers, cod liver oil, fish eggs, poultry eggs, etc.Carrots, spinach, amaranth, alfalfa, sweet potatoes, squash, green peppers and other vegetables contain vitamin A in the body can be converted to vitamin A.
2, Vitamin B group rich in food, the retina of the eye storage has a considerable amount of free vitamin B2.If the baby vitamin B group lack, will lead to photophobia, tears, burning pain and itching, visual fatigue, eye cramps.
3, Rich in vitamin C food, vitamin C is one of the components of the lens of the eye, the vitamin can also effectively inhibit cell oxidation, lack of vitamin C easy to make the baby dry eyes.
4, Rich in protein food, protein is the main component of cells, tissue repair and update need to constantly supplement protein.Eating more protein can make your baby's eyes bright.
5, Calcium, calcium and the composition of the eye, calcium deficiency can lead to myopia.Children are in the growth peak, calcium in the body of the relative increase in demand, do not pay attention to calcium supplement will not only affect bone development, and will make the developing eye wall - sclera elasticity is reduced, the pressure in the lens rise, causing the diameter of the eyeball before and after elongated and cause myopia.The food that contains much calcium basically has milk kind and its products, shell kind (shrimp), bone meal, bean and bean products, egg yolk and dark green vegetable.
6, Chromium, lack of chromium is prone to myopia, chromium can activate insulin, so that the pancreatic islet to play the maximum biological effect.The deficiency of chromium content in human body will cause the dysfunction of the function of insulin to regulate blood sugar, and the increase of plasma osmotic pressure will increase the osmotic pressure of the lens and aqueous humor of the eye and increase the diopter, thus inducing myopia.Chromium is found in brown rice and wheat bran. It is also found in animal liver, grape juice and nuts.
7. Zinc. Zinc deficiency can lead to visual impairment. Zinc is found in the body mainly in the bones and blood.Zinc is also found in the corneal epidermis, iris, retina and lens. Zinc is involved in the representation and transportation of vitamin A in the eye, maintaining the normal tissue status of retinal pigment epithelium and maintaining normal visual function.Foods with more zinc include oysters, meat, liver, eggs, peanuts, wheat, beans, grains and so on.
8, Pearls, pearl contains more than 95% of the calcium carbonate and a small amount of magnesium oxide, alumina and other minerals, and contain a variety of amino acids, such as leucine, methionine, alanine, glycine, glutamic acid, aspartic acid, pearl sexual flavour gan salty cold, with pearl powder with borneol, amber, etc into the "pearls" point of the eye can inhibit the formation of cataracts.
9, Kelp, kelp in addition to iodine also contains 1/3 of the mannitol, dried kelp surface has a thick layer of "white frost", it is the mannitol in kelp, mannitol diuretic effect, can reduce the pressure in the eye, used to treat acute glaucoma has a good effect.Other seaweeds, such as wakame, also contain mannitol and can be used as an adjunct in the treatment of acute glaucoma.
