Cataract and macular degeneration are the main causes of the deterioration of visual acuity and blindness, especially in the elderly. Cataract is characterized by the progressive blurring of the crystalline cone, which, in time, leads to sight decay. In spite of the fact that it is considered an inevitable health condition, which occurs as a result of aging, some experts claim that it can be effectively prevented, or even reversed with the help of an adequate diet.
- Foods rich in vitamin C and E
A healthy diet is the strongest weapon against aging and its imminent consequences. For instance, there is a wide range of nutrients that nourish and protect the eye, and which help preserve a healthy vision.
This is the main reason five portions of vegetables and fruits a day are essential after a certain age. Some of the most important foods you should include in your diet for maintaining the health of your eyes are those rich in vitamin C and E.
A scientific study shows us that a dosage of about 107 mg of vitamin C a day can considerably decrease the risks associated with cataract. In this respect, an orange contains about 70 mg of vitamin C.
Another study points that a dosage of 8 mg of daily vitamin E intake can protect the eyes from developing cataracts.
Ideal sources of vitamin C include broccoli, cauliflower, cabbage, kale, peas, and tomatoes.
Great sources of vitamin E include spinach, avocado, pumpkin, sunflower seeds and so on.
According to research, a varied diet rich in vegetables and fruits can contribute to decreasing the risks of developing an eye-related problem.
This particular ingredient presents the amazing capacity of reducing the oxidation of the crystalline cone, which is the major cause of the majority of visual issues. Curcumin, which is an active compound found in turmeric, is a powerful polyphenol that remarkably protects the eyes from the formation of cataracts. Studies developed in rats show that the crystalline cone of the rats that were fed with curcumin extract was increasingly more resistant to eye-related problems.
Plus, turmeric encompasses anti-inflammatory properties as well, which can contribute to reducing inflammation associated with eye dryness.
- B vitamins
A diet rich in B complex vitamins ensures the health of the eyes, protecting them from developing cataract. Additionally, vitamin B6 has been proven to present protective properties concerning age-related eye issues.
- Foods rich in lutein
Lutein is a powerful antioxidant present in green veggies, fruits, yolk, and calendula. Additionally, lutein is present in the macula, also in small quantities in the retina, crystalline, and optical nerve. The consumption of foods rich in lutein prevents blindness and macular degeneration while at the same time decreasing the risks of developing cataracts.
Eye-related problems often occur because of the harmful effects of free radicals. Thus, given the fact that bilberries contain important levels of powerful antioxidants, they are recommended for preventing and treating multiple eye disorders associated with aging.
Wheatgrass is considered a miraculous supplement, presenting a myriad of health benefits for preserving the overall health. Additionally, studies conducted on aged dogs show that wheatgrass extract is effective in reversing the symptoms associated with cataract.
