The eyes are one of the hardest-working organs in the human body, and as such, they are particularly prone to fatigue and aging due to overwork. Eyes that have worked hard also need nutritional supplementation through food. Recently, a study by the University of Manchester in the UK confirmed that spinach is one of the best sources of lutein, which is highly effective in preventing "macular degeneration" caused by eye aging.
Researchers from Ohio State University in the United States also stated that the large amount of lutein found in dark green leafy vegetables like spinach is very helpful in preventing cataracts. According to research, leafy green vegetables are also good sources of vitamin B2 and beta-carotene. When there is sufficient vitamin B2, the eyes are less likely to become bloodshot. Beta-carotene can be converted into vitamin A in the body, preventing conditions such as "dry eye syndrome."
Spinach, among the green leafy vegetables, offers even more benefits. It is rich in potassium, calcium, and magnesium, which help enhance the elasticity of the eye muscles, making it less likely for myopia to develop. It is well known that people with calcium deficiencies have poor eye elasticity and are more prone to elongated eye axes. Researchers also pointed out that a daily diet consisting of white rice, stir-fried meat, braised fish, sweetened beverages, and desserts can lead to significant calcium loss in the body. If one could eat less meat and more spinach, this deficiency could be compensated for, greatly benefiting the enhancement of eye muscle elasticity.
