According to a new meta-analysis a higher consumption of Carotenoids and certain Vitamins is associated with a significantly decreased risk for Age Related Cataract (ARC) formation.
8 randomized controlled trial (RCTs) and 12 cohort studies were included in this meta-analysis. These studies, published through June, 2018, assessed dietary Carotenoid and Vitamin intake and ARC risks.
The meta-analysis found most Carotenoids (Beta Carotene, Lutein and Zeaxanthin) and Vitamins A, C, and E were associated with significant reductions in ARC risks. The risk for ARC decreased 26% for every 10 mg/d increase in Lutein or Zeaxanthin intake, 18% for every 500 mg/d increase in Vitamin C intake, 8% for every 5 mg/d increase in Beta Carotene, and 6% for each 5mg/d increase in Vitamin A.
