Carrots for Eye Health

Research suggests that carrots, as a rich dietary source of beta-carotene, may support eye health primarily through beta-carotene's role as a vitamin A precursor and its antioxidant properties, with a 2024 review linking beta-carotene intake to reduced risk of eye-related disorders alongside other health outcomes. A separate 2013 review focused on lutein and zeaxanthin — carotenoids more directly associated with retinal protection and reduced risk of age-related macular degeneration and cataracts — noting that while carrots contain some of these pigments, foods like leafy greens and eggs are more concentrated sources, which introduces some nuance when attributing eye health benefits specifically to carrots. The available evidence comes primarily from review articles and observational or epidemiological research rather than controlled clinical trials specifically on carrot consumption, and two of the linked studies focused on beta-carotene production in yeast and carrot genetics, offering mechanistic context rather than direct human health findings. Studies indicate a generally supportive but not conclusive picture, and readers should be aware that the broader carotenoid research encompasses many foods and compounds beyond carrots alone.
