Common fruits that are high in vitamin C include oranges, strawberries, kiwi, guavas, and papayas. These fruits contain significant amounts of this essential nutrient, which is vital for immune function and skin health. Incorporating vitamin C-rich fruits into the diet can enhance antioxidant defenses, support collagen production, and improve overall health. Including a variety of these fruits ensures adequate intake of vitamin C, especially during cold and flu seasons, when the body may require additional support for its immune system.
