The health of your vision depends on daily care. So, do you know how to choose fruits in your daily life to protect your vision?
Modern people are prone to vision problems due to work and life reasons. Therefore, for women, choosing the right fruits is a good way to protect their vision.
1. Foods that improve vision
To protect vision and prevent eye diseases, it is necessary to work on multiple aspects, among which paying attention to nutrition also helps to improve vision. In daily diets, foods that improve vision include:
(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 prolonged, and in severe cases, it can lead to night blindness. If the diet continues to lack or be insufficient in Vitamin A, xerophthalmia may occur. This disease can further develop into corneal softening and corneal ulcers, and corneal folds and Bitot's spots may also appear. The best food sources of Vitamin A are various animal livers, cod liver oil, fish roe, poultry eggs, etc. The Vitamin A precursors in vegetables such as carrots, spinach, amaranth, alfalfa, red sweet potatoes, pumpkins, and green peppers can be converted into Vitamin A in the body.
(2) Foods rich in Vitamin C, which can reduce the damage of light and oxygen to the eye's lens, thereby delaying the onset of cataracts. Foods containing Vitamin C include bell peppers, tomatoes, lemons, kiwis, hawthorns, and other fresh vegetables and fruits.
(3) Calcium, which is related to the structure of the eyeball. A lack of calcium can lead to myopia. Adolescents are in a period of peak growth, and their body's demand for calcium is relatively increased. If calcium supplementation is not noted, it will not only affect bone development but also reduce the elasticity of the sclera—the outer layer of the developing eyeball—increase the intraocular pressure of the lens, and lengthen the anteroposterior diameter of the eyeball, leading to myopia. Foods rich in calcium mainly include dairy products and their derivatives, shellfish (shrimp), bone meal, beans and bean products, egg yolks, and dark green vegetables.
(4) Chromium, a deficiency of which can easily lead to myopia. Chromium activates insulin, allowing the pancreas to exert its maximum biological effect. If the body's chromium content is insufficient, it will cause a disorder in insulin's blood sugar regulation function, increase plasma osmotic pressure, and consequently increase the osmotic pressure and refractive power of the eye's lens and aqueous humor, thus inducing myopia. Chromium is mostly found in brown rice, wheat bran, and is also relatively abundant in animal livers, grape juice, and nuts.
(5) Zinc, a deficiency of which can lead to vision impairment. Zinc is mainly distributed in bones and blood in the body. It is also present in the corneal epithelium, iris, retina, and lens. Zinc participates in the metabolism and transport of Vitamin A in the eye, maintains the normal tissue state of the retinal pigment epithelium, and maintains normal visual function. Foods rich in zinc include oysters, meat, liver, eggs, peanuts, wheat, beans, and coarse grains.
(6) Pearl, which contains more than 95% calcium carbonate and small amounts of minerals such as magnesium oxide and aluminum oxide, and also contains various amino acids such as leucine, methionine, alanine, glycine, glutamic acid, and aspartic acid. Pearl is sweet, salty, and cold in nature. "Pearl Powder," made with pearl powder and borneol, amber, etc., can be applied to the eyes to inhibit the formation of cataracts.
(7) Kelp, which, in addition to iodine, contains one-third of mannitol. The surface of dried kelp has a thick layer of "white frost," which is the mannitol in the kelp. Mannitol has a diuretic effect and can reduce intraocular pressure, making it effective in treating acute glaucoma. Other seaweeds such as wakame also contain mannitol and can be used as an auxiliary food for treating acute glaucoma.
2. Health foods that help improve vision
Diet can increase nutrition and improve vision, so we should consume more of the foods mentioned above. If, on the basis of a daily diet, appropriate health foods with vision-improving functions are selected, it can play a good auxiliary therapeutic role. The selectable health foods include:
(1) Foods rich in Vitamin A, such as products made from wolfberry.
(2) Foods rich in protein, peptides, certain amino acids, such as taurine, nucleic acids, etc.
(3) Health teas, granules, or capsules containing cassia seed, chrysanthemum, hawthorn, pearl powder, etc.
