What foods to eat help with vision?

To put it simply, the trace elements that help vision are vitamin A, followed by calcium, vitamin B and vitamin C. Vitamin A, also known as retinol, plays an important role in the formation of human vision. It is involved in the synthesis of rhodopsin in the retina, and if vitamin A is insufficient, the eye's ability to adapt to dark environments will be reduced, and in severe cases, it may lead to night blindness.

Vitamin A can also promote the growth and differentiation of epithelial cells, and if it is deficient, it will become thicker and drier. In addition, vitamin A deficiency may also reduce the body's resistance to infectious diseases, and in children and adolescents, it may affect growth and reproductive function. Vitamin A**:

Animal liver, cod liver oil, caviar, whole milk and whole dairy products, eggs and other contents are higher. The carotene contained in plant vegetables can be converted into vitamin A in the human body, hence the name provitamin A. Provitamin A is abundant in green and yellow vegetables, fruits such as spinach, leeks, pea sprouts, alfalfa, green peppers, sweet potatoes, carrots, pumpkin, apricots, and mangoes.

Carotene is fat-soluble, and eating it with oil can promote its absorption, for example, eating fried shredded carrots is easier to absorb than eating raw carrots. Calcium is the "protector" of the eye tissue. If there is a lack of calcium in the body, it will not only cause the elasticity of the retina of the eye, the pressure in the lens will rise, and the anterior and posterior diameter of the eye will be elongated, but also the cornea and ciliary muscle will degenerate, which will easily cause vision loss or myopia.

Dairy, legumes, edible mushrooms, dried fruits and seafood are rich in calcium, cod liver oil, animal liver, dairy products and egg yolks are rich in vitamins. The trace elements selenium, zinc and chromium are also beneficial to improve the function of eye tissues and prevent and treat vision loss. Foods containing more selenium include animal liver, eggs, fish, shellfish, soybeans, mushrooms, asparagus, camellia, carrots, etc.; Foods containing more zinc include liver, kidney, seafood, milk, cereals, beans, hard fruits, etc.; Foods that contain more chromium include beef, black pepper, brown rice, corn, millet, semolina, brown sugar, grape juice, edible mushrooms, etc.

Foods rich in vitamin A: such as carrots, amaranth, spinach, leeks, green peppers, sweet potatoes, and oranges, apricots, persimmons, etc. Foods rich in vitamin B complex:

Foods rich in B vitamins include whole grains, liver, yeast, yogurt, wheat germ, legumes, milk (vitamin B2), meat (vitamin B1, niacin). Foods rich in vitamin C: such as fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, bok choy, fresh dates, pears and oranges are the highest.

Protein-rich foods: Lean meats, animal offal, fish and shrimp, milk, eggs, legumes and other foods are rich in protein, and protein is the main component of cells, and the eyes are no exception. Calcium-rich foods:

Beans, green leafy vegetables, shrimp skin, and milk are rich in calcium. Cooking methods such as roasted pork rib soup and sweet and sour pork ribs can increase the calcium content. Ensuring that your baby drinks 2 cups of milk a day can ensure calcium intake.

With the acceleration of the pace of life, the increasing pressure of work, air pollution, and chemicals, overuse of eyes, malnutrition, eye diseases, bad eye habits, etc. may be the cause of your current situation Beneficial to the eyes 1. Provide sufficient vitamin A: Vitamin A is an important raw material for the composition of eye photosensitive substances, which has the function of protecting the eyes and other epithelial tissues and indirectly resisting infection. Vitamin A is abundant, which can increase the finish of the cornea, making the eyes bright and looking radiant.

2. Supplement enough protein: The rhodopsin on the retina of the eye is composed of protein, and when it is deficient, in addition to muscle weakness, poor development, easy infection, edema, anemia, visual impairment will also occur. Therefore, it is important to give your child more foods with high protein content, such as lean meat, fish, milk, eggs and soy products.

3. Calcium and phosphorus are indispensable: calcium and phosphorus can make the sclera tough and participate in the physiological activities of the optic nerve. When calcium and phosphorus are deficient, it is easy to cause visual fatigue, distraction, and myopia.

4. Vitamin C, B1 and B2 are indispensable: Vitamin C is an important nutrient component of the eye lens, and insufficient intake will make the eye lens cloudy, and is one of the important causes of cataracts. Foods rich in vitamin C include oranges, mandarins, pomelo, tomatoes, various fruits and vegetables, etc., and the content of fresh dates and kiwifruit is even richer.

Vitamins B1 and B2 are important substances involved in the metabolism of nerve cells including the optic nerve, and have the effect of protecting the eyelid conjunctiva, bulbar conjunctiva and cornea, and can also prevent and delay the formation of lateral canthus and tail lines at the corners of the eyes. 5. Trace elements cannot be ignored: Although the content of trace elements in the human body is less than 1 percent of body weight, it has a great effect.

Without them, metabolism is difficult to carry out, and children's health suffers. Trace elements such as zinc, chromium, molybdenum, selenium, etc., also participate in the metabolism of various substances in the eye, regulate their physiological functions, and cannot be ignored. Good eye habits The posture of reading and writing should be correct, and the reading time should be rested for a while; Do not read in dim light and direct sunlight, and do not stay in bed, ride in a car, or walk into the house to read.

The body is a fist away from the desk, the index finger is an inch away from the tip of the pen, and the eyes are a foot away from the desk. There are many types of eye drops and ointments, most of which are antibacterial and anti-inflammatory drugs or hormone-containing eye drugs. For bacterial conjunctivitis and keratitis, we often use chloramphenicol eye drops as the main ingredient.

It is best to see a doctor, eat more physical objects that are good for the eyes, and develop good habits.

What you eat, what you eat, optical fiber eats your eyes, you are eating something else.

What to eat, what to make up for eating human eyes.

Eat animal liver (pork liver, chicken heart, chicken liver).

Eat more vegetables and fruits.

Foods that have a vision-improving effect.

1.Foods rich in vitamin A: Vitamin A 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, night blindness is caused.

If dietary vitamin A deficiency or insufficiency continues, dry eye disease will occur, and further development of the disease can lead to corneal transformation and corneal ulcers, as well as corneal folds and Bitot's spots. Vitamin A best food** all kinds of animal liver, cod liver oil, fish eggs, poultry eggs, etc.; The provitamin A contained in vegetables such as carrots, spinach, amaranth, alfalfa, red hearts, pumpkin, and green peppers can be softened into vitamin A in the body.

2.Vitamin C-rich foods can reduce the damage of light and oxygen to the lens of the eye, thereby delaying the onset of cataracts. Foods rich in vitamin C are fresh vegetables and fruits such as persimmons, lemons, kiwis, hawthorns, etc.

3.Calcium calcium is related to the composition of the eyeball, and calcium deficiency can lead to myopia. If you do not pay attention to calcium supplementation, it will not only affect the development of bones, but also reduce the elasticity of the developing eyeball wall - sclera, and increase the pressure in the lens, resulting in the elongation of the anterior and posterior diameters of the eyeball, resulting in myopia.

4.Chromium deficiency is prone to myopia, chromium can activate insulin, so that insulin to exert the maximum biological effect, such as insufficient chromium content in the human body, it will make insulin dysfunction, plasma osmolality increase, resulting in the lens of the eyeball, aqueous humor osmotic pressure increase and refraction increase, thereby inducing myopia. The daily physiological requirement of the human body for chromium is:

Chromium is mostly found in brown rice and wheat bran, and is also abundant in animal liver, grape juice, and nuts.

5.Zinc deficiency can lead to visual disturbances, and zinc is mainly found in the bones and blood in the body. The corneal epidermis, iris, retina and lens also contain zinc, which is involved in the metabolism and transport of vitamin A in the eye, maintaining the normal tissue status of the retinal pigment epithelium and maintaining normal visual function.

Foods that contain more zinc include oysters, meat, liver, eggs, peanuts, wheat, beans, and grains.

6.Pearl pearls contain more than 90% calcium carbonate and a small amount of magnesium oxide, alumina and other inorganic salts, and contain a variety of amino acids, such as leucine, methionine, alanine, glycine, glutamic acid, aspartic acid, etc. Pearls are sweet and salty in nature, and the formation of cataracts can be inhibited by the "true pearl scattering" point of pearl powder with borneol, amber, etc.

7.In addition to containing iodine, kelp also contains 1 3 mannitol, and there is a thick layer of "hoarfrost" on the surface of the dried kelp, which is mannitol in kelp, mannitol has a diuretic effect, which can reduce intraocular pressure and has a good effect on acute glaucoma. Other seaweeds such as wakame also contain mannitol and can also be used as a supplementary food for acute glaucoma.

The eyes are important organs of the human body, and they are used excessively, such as when reading, engraving, embroidering, and watching television.

Too long of activity can cause eye fatigue, general fatigue, and extreme mental tension; Malnutrition, too.

Can cause vision loss. Common symptoms of eye strain are headache, forehead swelling, dry eyes, and long-term eyes.

Fatigue can cause vision loss and reduced work efficiency. Protect your eyes, except for the usual attention to the combination of work and rest, no.

You should read books and watch TV for a long time, do eye exercises regularly, and eat foods that are good for your eyes.

Protecting your eyes can also play a big role. So what are the foods that are good for the eyes? Such as lean meat, poultry.

Animal offal, fish and shrimp, milk, eggs, legumes, etc., are rich in protein, and protein is.

The main component of the cell, the repair and renewal of tissues, requires constant replenishment of protein, vitamin A-containing food.

It is also good for the eyes, and when vitamin A is deficient, the ability of the eyes to adapt to the dark environment is reduced, which is severe.

It is easy to suffer from nocturnal wandering syndrome. Vitamin A can also prevent and ** dry eye disease. When there is a chronic deficiency of vitamin A.

To eliminate eye fatigue, you should consume enough vitamin A every dayThe best** of vitamin A is from all kinds of animals.

Liver, cod liver oil, milk and eggs, plant-based foods such as carrots, amaranth, spinach, leeks, greens.

Peppers, red sweet potatoes, and fruits such as oranges, apricots, persimmons, and other carotene. Contains vitamin C.

Food is also good for the eyes. Vitamin C is one of the components that make up the lens of the eyeball. If there is a deficiency of vitamin C.

Cataract disease that is prone to cloudy lenses. Therefore, it is important to take care of vitamin C in your daily diet

Abundant foods, such as a variety of fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, and whites.

Vegetables, fresh dates, raw pears and oranges have the highest content. Rich calcium powder is also good for the eyes, calcium has the ability to eliminate.

The effect of eye tension. For example, beans, green leafy vegetables, and shrimp skin are rich in calcium. Grilled pork rib soup and pine fish.

Cooking methods such as sweet and sour pork ribs can also increase the calcium content.
