How might nutrition prevent and/or treat of cataracts and macular degeneration?

Correct Answer

verifed

Oxidative stress appears to play a significant role in the development of cataracts,but supplements of the antioxidant nutrients (vitamin C,vitamin E,and carotenoids)do not seem to prevent or slow the progression.By comparison,a healthy diet that includes plenty of fruits and vegetables rich in these antioxidant nutrients does seem to slow the progression or reduce the risk of developing cataracts.A word of caution: vitamin C supplements in high doses (1000 milligrams)and long duration (several years)may increase the risk of cataracts.One other diet-related factor may play a role in the development of cataracts- obesity.Obesity appears to be associated with cataracts,but its role has not been identified.Risk factors that typically accompany obesity,such as inactivity,diabetes,or hypertension,do not explain the association.The leading cause of visual loss among older people is age-related macular degeneration,a deterioration of the macular region of the retina.As with cataracts,risk factors for age-related macular degeneration include oxidative stress from sunlight.Preventive factors may include supplements of the omega-3 fatty acids,some B vitamins (folate,vitamin B6,and vitamin B12),antioxidants (vitamin C,vitamin E,and beta-carotene),zinc,and the carotenoids lutein and zeaxanthin.
