June 6 is National Eye Care Day. In daily life, besides eye hygiene, work and rest, there is nothing closer to eye health than diet. A proper dietary structure is the basis for eye nutrition and health. The eye is a complex visual nervous system with high nutritional needs, so it is important to take in a balanced and comprehensive nutrition, and not to waste one of them. There are two types of foods that are not good for the eyes: sweets and garlic. Generally speaking, sweets should not be eaten too much, but a little is fine, while garlic is fine if eaten sparingly, but a little more will quickly cause a reaction in people with sensitive bodies. Most people only know that eating sweets often tends to increase weight and cause metabolic diseases, but in fact, it also has a very big impact on eye health and can induce or aggravate some eye diseases, such as: cataract, myopia, optic nerve atrophy, etc. Eating too many sweets can easily contribute to the deterioration of these eye diseases. The sugar contained in sweets needs a lot of vitamin B1 when metabolized in the human body. Excessive intake of sugar in the human body will consume a lot of vitamin B1, which is one of the indispensable nutrients for the eyes, and the lack of access to this important element for the eyes will lead to the occurrence of many eye diseases. Excessive consumption of garlic is equally harmful to the eyes. Garlic is a very good vegetable and has a preventive effect on many diseases. However, if garlic is consumed in excess for a long period of time, especially for people with eye diseases and those who have frequent fever, hot flashes and night sweats, etc., eating too much garlic can have adverse consequences. There is a folk saying that “garlic has a hundred benefits but only harms the eyes”. Therefore, elderly people suffering from eye diseases should pay attention to this during treatment, otherwise it will affect the effectiveness of treatment. Water is the source of life, and the health of the eyes cannot be separated from water. Talking about eye health, the first thing that should not be neglected is to maintain an adequate supply of water. Both young and old should get into the habit of drinking more water, plain water, tea and beverages, so that the eyes are always maintained and moisturized by water, which is essential to maintain eye health. The main material basis of the visual system is composed of protein and vitamin A derivatives together, and a lack of these two substances may cause night blindness and cataracts. The main sources of high quality protein are milk, eggs and animal meats. Foods rich in vitamin A are mainly animal offal, vegetables such as carrots, pumpkins and green leafy vegetables, and fruits such as citrus and oranges. The B vitamins are important substances involved in the metabolism of nerve cells, including the optic nerve, and protect the eyelids, conjunctiva and cornea. Friends who use computers frequently, have or have not yet developed dry eyes, and patients with diabetic eye complications can take appropriate supplements of these vitamins. Foods rich in B vitamins include peanuts, beans, millet, animal offal, meat, eggs, fish, rice bran, peas, etc. Vitamin C is an important nutrient for the lens of the eye and its deficiency can lead to clouding of the lens, loss of vision and consequently cataracts. Simply adding tomatoes, peppers, citrus fruits, kiwis, berries and cauliflower to your daily menu is generally enough to ensure your vitamin C intake. Zinc, chromium, calcium, molybdenum, selenium and copper are also involved in the synthesis of various substances in the eye and regulate their physiological functions, which are important for maintaining eye health. Foods rich in selenium mainly include animal liver, kidney, purple amaranth, asparagus, mushrooms, garlic, sesame, etc. Foods rich in calcium include milk and its products, beans and soy products, fish, dark green vegetables, kelp, nori, egg yolk, melon seeds, walnuts, peanuts, etc. Foods rich in zinc include oysters, meat, liver, eggs, peanuts, almonds, wheat, fish, beans, chestnuts, coarse pasta, brown rice, etc. Chromium is found in brown rice, coarse pasta and wheat bran. Foods rich in copper include animal liver, soybeans and soy products, peanuts, walnuts, hard-shelled fruits, and crustaceans.
