VITAMIN C helps our body absorb iron and helps to keep body cells (细胞) healthy. What’s more, as an antioxidant (抗氧化物), it may give us protection from illness. Since the body doesn’t store vitamin C, we should eat high-C foods daily. Good sources (来源) include apples, watermelon, lemons, oranges, dark leafy green vegetables, peppers, potatoes and tomatoes.
