The fruit known for being particularly high in vitamin C is the orange. Oranges are citrus fruits that are not only deliciously sweet and juicy but also provide a significant amount of this essential nutrient, which is crucial for maintaining a healthy immune system. Just one medium-sized orange can provide about 70 mg of vitamin C, exceeding the recommended daily intake for adults. In addition to vitamin C, oranges are a good source of dietary fiber, folate, and antioxidants. Consuming oranges can help enhance skin health and may reduce the risk of chronic diseases.
