Dry eyes are a common condition today due to many reasons such as excessive use of electronic devices, polluted environment, or a diet lacking essential nutrients.
Sweet potatoes contain a very high beta-carotene content, which is a precursor to vitamin A. Just a medium-sized sweet potato, about 130g, provides more than 400% of your daily vitamin A needs in the form of beta-carotene. When entering the body, beta-carotene is converted into vitamin A - an essential nutrient that helps protect and maintain the health of the eye surface, as well as prevent dry eyes.
The World Health Organization also emphasizes the important role of vitamin A in the prevention of eye diseases, especially cornea dryness and retinopathy. The World Health Organization warns that vitamin A deficiency is a leading cause of preventable blindness in children, and improving vitamin A intake through natural foods is the most effective way.
Research shows that supplementing foods rich in beta-carotene, especially from sweet potatoes and carrots, significantly improves tear levels and reduces symptoms of dry eyes after 8 consecutive weeks of use.
Sweet potatoes also contain vitamins C, E and other antioxidants ingredients that help reduce inflammation, improve corneal health and maintain natural moisture for the eyes.
