Citrus fruits, particularly oranges, are well-known for their high vitamin C content. A medium-sized orange typically provides about 70 mg of vitamin C, which is around 78% of the daily recommended intake for adults. This vitamin is crucial for many bodily functions, including the synthesis of collagen, absorption of iron, and supporting the immune system. Other fruits, like kiwis, strawberries, and guavas, also boast significant vitamin C levels. Incorporating these fruits into your diet can enhance your overall health and help in preventing various diseases. Therefore, oranges and other similar fruits are excellent choices for boosting vitamin C intake.
