Which of the following foods is high in vitamin C?

Oranges are widely recognized as a significant source of vitamin C, which plays a crucial role in various bodily functions such as the maintenance of healthy skin, blood vessels, and immune function. A medium-sized orange typically contains about 70 mg of vitamin C, which meets and even exceeds the daily recommended intake for adults.

The high vitamin C content in oranges is beneficial for preventing nutritional deficiencies and is essential for the synthesis of collagen, a protein that aids in the healing of wounds and the maintenance of healthy connective tissues. Other fruits and vegetables, such as strawberries, kiwis, and bell peppers, also contain high levels of vitamin C, but in this case, oranges are particularly well-known for their association with this vitamin.

In contrast, apples, cereals, and bananas contain lower amounts of vitamin C when compared to oranges. For example, apples might provide some vitamin C, but at a significantly lower level than oranges. Cereals often do not contain vitamin C unless fortified, and bananas also have relatively low amounts of this important nutrient. Thus, oranges clearly stand out as the food option highest in vitamin C among the choices presented.
