dietotherapy is an effective way to prevent diseases and protect health by using food. Ancient doctors said that "medication is not as good as dietotherapy". Traditional Chinese medicine believes that the eyes are also a part of an organic whole with internal relations between zang-fu organs and meridians, and dietotherapy is helpful to prevent and treat eye diseases such as dry eye and asthenopia. \x1d\ Foods that usually contain a lot of vitamin A, vitamin B1 and vitamin C, such as animal liver, lean meat, fish and shrimp, milk, beans, peanuts, almonds, walnuts, etc., vegetables such as green peppers, spinach, amaranth, leeks, etc., and fruits such as pears and oranges, have a good health care effect on eyes and can prevent eye dryness, visual fatigue and aging. \x1d\ In recent years, according to scientists' research, the occurrence of myopia is closely related to the intake of a nutrient called lutein. Lutein belongs to "carotenoid", which is high in fresh green vegetables and citrus fruits. Lutein plays an important role in protecting the "macula" in the retina. If lutein is lacking, it will easily cause macular degeneration and lead to blurred vision. Now is the season when a large number of citrus fruits are on the market. Ophthalmologists suggest that everyone should eat more citrus fruits every day to prevent vision degradation, which is especially suitable for students and office workers who use computers for a long time. \x1d\ At the same time, according to the theory of "homology of medicine and food", adding some Chinese medicines that can be used as medicine in daily diet can also play a better role in preventing eye diseases. In winter, Chinese medicines suitable for eye tonic such as Lycium barbarum, longan pulp, cassia seed, mulberry seed, chrysanthemum morifolium, yam, Ophiopogon japonicus, jujube, black bean, etc. Here, I would like to recommend several common recipes of Chinese medicine "eye tonic": \x1d\1. Pork liver soup with Lycium barbarum: 111g of pork liver and 31g of Lycium barbarum \x1d\ First, slice the pork liver, mix well with proper amount of starch, put it in the pot with Lycium barbarum, and add water to soup for seasoning. This is an ancient diet prescription for the treatment of night blindness. Pig liver is rich in vitamin A and Lycium barbarum contains carotene, so it has a certain positive effect on vision fatigue and eye care. \x1d\2. Chrysanthemum eyesight-improving porridge: 21g of chrysanthemum and 61g of japonica rice \x1d\ Grind dried chrysanthemum for later use, and when the japonica rice porridge is cooked until it is thick, add chrysanthemum powder and appropriate amount of crystal sugar to taste. Once a day in the morning and once a night. This prescription has the effects of dispelling wind and heat, clearing liver fire, regulating qi and blood, improving eyesight and caring skin, and is suitable for office workers with red eyes and swelling pain due to liver fire or long-term computer use. \x1d\3. Walnut, jujube, wolfberry and egg soup \x1d\ 311g of walnut kernel, 251g of jujube, 151g of medlar and 211g of fresh pig liver, add a little water and stew for half an hour. Take 2~3 tablespoons a day, beat in 2 eggs, add some sugar and steam into a soup. This recipe is beneficial to kidney and liver, nourishing blood and improving eyesight. It can prevent myopia, vision loss and some senile eye diseases. \x1d\ Traditional Chinese medicine tonic methods are varied and flexible. For patients with eye fatigue, appropriate amount of Angelica sinensis can be added to the above recipes; Ophiopogon japonicus and mulberry seeds can be added for dry eyes; Cataract, macular degeneration can eat more black beans, yam and so on. \x1d\ Need to remind everyone that Chinese medicine tonic should be implemented dialectically according to physical fitness. For most middle-aged and elderly patients, there are symptoms of liver and kidney loss and insufficient yin and body fluid, so the above method is suitable for Chinese medicine tonic; For patients with excessive liver fire, Hangzhou chrysanthemum is suitable for eye repair; At the same time, patients with hyperlipidemia and other diseases, animal liver and medlar should not be ingested in large quantities, and vegetables and fruits should be used instead.
