Anti-oxidants are protective against cataracts

Anti-oxidants are protective against cataractsA total of 13 observational studies with 18,999 participants were included in this meta-analysis. The studies evaluated the risk of cataract in association with blood levels of vitamin A, vitamin C, vitamin E, alpha-carotene, beta-carotene, lutein, zeaxanthin, lycopene and beta-cryptoxanthin.

The authors found that high serum vitamin E, α-carotene, lutein and zeaxanthin levels were each associated with a 25 to 30 percent lower risk of developing cataracts. Vitamin A and C were associated with a 31 to 33 percent risk reduction. The effect, however, was  observed in Asian but not Western populations. Beta-carotene, lycopene, and β-cryptoxanthin were not associated with a decreased risk of cataracts.

Based on these findings, antioxidants might have a protective effect against cataract, highlighting the importance of eating a diet that is rich in antioxidant vitamins and carotenoids.
