Surprising Benefits of the Humble Eggplant

5. Preserve Vision

Folk remedies in some tropical areas used eggplant to relieve vision problems. Although the effectiveness of such remedies is impossible to determine, we now know that eggplants contain lutein, zeaxanthin, zeaxanthin, resveratrol, and vitamin C. These nutrients all enhance eye health. A Japanese study finds that anthocyanin in black currants correlated with increased blood flow to optic nerves and stabilized fields of vision in people with glaucoma. Eggplants also contain anthocyanin, which may partially explain its traditional use for vision problems.
