In modern society, people spend more and more time looking at electronic screens such as mobile phones and computers, which increases the degree of Eye strain. One of the direct effects of Eye strain is myopia. In addition, Eye strain can also accelerate eye aging. In addition to paying attention to eye hygiene, eating the following foods regularly can also improve Eye strain and protect eyes. Pig liver: Supplementing vitamin A is a crucial vitamin for vision. Especially for people who often watch electronic screens, they should eat foods that contain more vitamin A. The requirement for adult vitamin A is 800 micrograms of RAE/day for males and 700 micrograms of RAE/day for females. There are two types of food sources for vitamin A: plant-based and animal based. In plant-based foods, green or yellow fruits and vegetables such as spinach, leeks, pea seedlings, alfalfa, green peppers, sweet potatoes, carrots, pumpkins, apricots, and mangoes contain β- Carotenoids are abundant and can be converted into vitamin A upon entry into the body. In animal food, animal liver, Cod liver oil, milk and eggs are high in content, which is a good source of vitamin A. The content of vitamin A in pig liver is 4972 micrograms per day, which is very rich. However, it should be noted that its purine and cholesterol levels are also relatively high. In terms of consumption, for animal viscera, adults who do not have dietary restrictions generally consume 2-3 times a month, each time around 25 grams (raw weight). Wheat germ: Supplementing vitamin B1 is one of the nutritional sources for the visual nerve. Insufficient vitamin B1 can cause eye fatigue. In addition, many people nowadays like to eat sweets, and excessive consumption of sweets can consume a large amount of vitamin B1 in the body, which can also lead to decreased vision. Vitamin B1 has a rich food source, including grains, potatoes, beans, yeast, hard fruits, animal hearts, liver, kidneys, lean meat, and eggs. Among them, the highest content is found in cereal germ, with wheat germ powder containing up to 3.5 milligrams per 100 grams. To eat wheat germ, you can add it in the cooked Congee or rice while it is hot, and then stew it for 3-5 minutes, or add it when making pasta. Kiwi fruit: supplement vitamin C Vitamin C is one of the ingredients that make up the eye lens. Adequate intake of vitamin C will help delay the aging and aging of the eyes and alleviate Eye strain. Rosa roxburghii, fresh dates, colored peppers, Bok choy, kiwi fruit, strawberries, broccoli, cauliflower, etc. are all rich in vitamin C. Here we recommend kiwifruit, which can be purchased almost all year round and is relatively convenient to eat. Its vitamin C content is as high as 62 milligrams per 100 grams. Eating a regular sized kiwi can meet 1/2 of the daily vitamin C requirement. When eating, be careful. As kiwifruit can easily stimulate the stomach and intestines, it is not recommended to eat on an empty stomach. It is best to place it between two meals and not exceed three per day.
