Five key nutrients for the prevention and treatment of cataracts and macular degeneration
Dietary factors play a key role in the prevention and treatment of cataracts and macular degeneration. A diet high in brightly colored fruits and vegetables, as well as targeted supplements, reduces the risk of both diseases.
Lutein and Zeaxanthin
Lutein and Zeaxanthin: Research shows that lutein and zeaxanthin supplements not only help prevent macular degeneration but can even improve visual function in people with macular degeneration. In particular, patients with macular degeneration receiving 10-15 mg of lutein per day led to a significant improvement in their condition: to restore glare, increase contrast sensitivity and visual acuity compared with the placebo group.
Lutein is also important for preventing cataracts and improving visual function in people with existing cataracts. Natural human lens in the same way as the macula, accumulate lutein and zeaxanthin. In fact, it’s the only carotenoids in the human body, and they are in the lens of the human eye. Three large studies have shown that consumption of lutein was associated with a significant reduction in the risk of cataract development.
Extracts rich in flavonoids
Extracts, rich in flavonoids: flavonoids Rich extracts of blueberry, bilberry, pine bark, or grape seed also have valuable benefits for eye health. In addition to the high antioxidant activity, these extracts have been shown to increase blood flow to the retina and improve visual processes, especially poor night vision. Take 150-300 mg per day of one of these extracts to support eye health.
Dietary antioxidants such as beta-carotene, vitamins C and E, zinc, copper and selenium are extremely important for eye health. Research conducted by the Research group involved in age-related eye diseases confirm that the combination of these nutrients produces better results than any of them individually. But even the reception for something very simple, such as vitamin C or zinc can lead to dramatic consequences. In one study it was shown that women who took vitamin C for more than 10 years had a 77 percent lower level of cataract formation compared to women who did not take the vitamin.
Zinc plays an important role in the metabolism of the retina and the vision process. A two-year study involving 151 participants have shown that in the group of participants taking zinc, loss of vision was much lower than in the placebo group.
Coenzyme Q10 and Acetyl-L-carnitine
As was shown in a double-blind clinical trial of 200 mg of acetyl-L-carnitine, omega-3 fatty acids (460 mg EPA and 320 mg DHA) and 20 mg of coenzyme Q10 improved visual function and led to positive changes in the early stage of macular degeneration. This combination stopped the progression of the disease in 47 of 48 cases.
Fish oil: There is a close relationship between atherosclerosis (hardening of the arteries) and eye health. Therefore, in the same way as in atherosclerosis, omega-3 fatty acids in fish oil play an important role in preventing macular degeneration and other eye diseases. The recommended dose is 1000 mg of EPA and DHA.
Food for your eyes
Foods rich in carotenoids such as lycopene, zeaxanthin, and lutein include peppers, carrots, greens, cabbage, papaya, spinach, sweet potatoes and tomatoes.
