Sweet Potatoes for Eye Health

Research suggests that sweet potatoes, as a source of beta-carotene, may support eye health through this carotenoid's antioxidant properties and its role as a precursor to vitamin A, both of which have been associated with vision support and reduced risk of eye-related disorders. The available evidence on this topic comes from a 2024 narrative review examining carotenoids broadly, which found associations between beta-carotene intake and eye health benefits, though review articles of this type summarize existing literature rather than establishing causation directly. It is worth noting that one of the two linked studies concerns seed potato microbiomes and crop vigor, and does not bear on human eye health at all, which meaningfully limits the breadth of the evidence base presented here. Readers should be aware that stronger evidence for sweet potatoes and eye health specifically would ideally come from controlled human trials or meta-analyses targeting this relationship directly.
