Eating this way will make the eyes of the old man brighter! Look at the elderly at home.

The eye is the window of the soul and the most precious sensory organ of the human body. However, the eye is the most delicate and most vulnerable organ. Therefore, if people want to have good vision, it is very important to “eat”.

Studies have shown that the visual acuity of middle-aged and elderly people is most closely related to long-term exposure to ultraviolet radiation, lack of vitamins, and dehydration.

The lens cells of the eye are mainly composed of crystallized proteins. The lens is exposed to ultraviolet light for a long period of time, and components such as lipids and proteins are damaged. When the damaged protein accumulates, it gradually changes from transparent to turbid to form a cataract.

There are high concentrations of antioxidants vitamin C and vitamin E in the lens, as well as some carotenoids of lutein and zeaxanthin. They are effective in preventing damage caused by UV rays and free radicals.

The more proteins that are damaged in the lens, the less proteases and antioxidants that protect them, and the more likely the lens is to develop cataracts and macular degeneration.

Prevention of cataract

Cataract is the leading blind eye disease in China. It is caused by the oxidative destruction of the crystal proteins of the eye, which makes the transparent crystals turbid.

In 2001, the US Department of Agriculture Senior Nutrition Research Center conducted a study of 478 women aged 53-73 years without diabetes and cataract. The results showed that with vitamin C, vitamin E, riboflavin, folic acid, Compared with women with the lowest intake of lycopene, beta carotene, lutein and zeaxanthin, women with adequate nutrient intake have a lower probability of developing cataracts;

Women who regularly eat vitamin C tablets have a 64% lower probability of developing cataracts than women who never eat vitamin C tablets;

Although lutein, zeaxanthin and lycopene have lower concentrations in the lens, they also play an important role in preventing the occurrence of cataract.

Therefore, middle-aged and elderly people often eat fresh fruits and vegetables rich in vitamin C, grapefruit, citrus, kiwi, grape, lemon, hawthorn, tomato, etc. , which is of great significance for preventing and reducing the occurrence of cataract.

According to reports, spinach, cabbage and broccoli have the highest levels of lutein and zeaxanthin, and lycopene has the highest content in cooked tomatoes, so it is appropriate to eat more. Carrots, bananas, green vegetables, etc. are also helpful in preventing and treating cataracts. In addition, to prevent cataracts, it is advisable to eat less animal fat.

Prevent macular degeneration

In the center of the retina, there is a 3 mm diameter macular, which is a low-sensitivity tissue film behind the retina, a visual tissue that plays a key role in the eye. The decomposition and degradation of photoreceptor cells are an important cause of age-related macular degeneration.

Studies have confirmed that high-energy blue light in sunlight has the strongest visual damage, while lutein and zeaxanthin in the macula absorb blue light and eliminate free radicals, thus protecting the retina.

Prevention of diabetic retinopathy

With the increasing number of diabetic patients in China, diabetic retinopathy is also increasing, and hypertension can increase the incidence of diabetic retinopathy.

Studies have found that low-sugar, high-protein, low-salt, low-fat diets can effectively prevent diabetes and diabetic retinopathy. Therefore, diabetic patients should choose low-sugar, low-salt (not more than 5 grams per day), low-fat diet (no more than 25 grams per day), should eat more high-quality protein foods.

Paying attention to glaucoma prevention and treatment of glaucoma is the third blind eye disease in China. Once it causes visual impairment, it will be irreparable. Studies have shown that the intraocular pressure of rice as a staple food and the intraocular pressure based on pasta are significantly reduced.

Therefore, glaucoma patients should use a low-fat diet based on rice to control the intake of carbohydrates and salt; pay attention to excessive drinking water (preferably take a small amount of drinking water), so as not to aggravate the edema of the eye tissue to aggravate the condition; usually milk Soymilk, juice, and other liquid diets should also be moderate; but also eat less spicy food such as green onions, ginger, garlic and pepper.
