Final answer:
The vitamin that aids in iron absorption and healing and is found in citrus fruits, melons, berries, and tomatoes is Vitamin C. It is a water-soluble vitamin essential for the immune system and must be consumed regularly as it is not stored in the body. An adult's daily requirement is approximately 70 mg.
Step-by-step explanation:
The nutrient found in citrus fruits, melons, berries, and tomatoes that aids in iron absorption and healing is Vitamin C.
D) Vitamin C. This water-soluble vitamin is essential for various bodily functions, including the absorption of iron from the intestine, which is vital for preventing anemia. In addition, Vitamin C plays a crucial role in the healing process and the maintenance of healthy connective tissues. High dietary intake of Vitamin C can reduce the severity and duration of the common cold, demonstrating its impact on the immune system.
Rich sources of Vitamin C include citrus fruits such as lemons and oranges, as well as green vegetables, cabbage, lettuce, guavas, berries, melons, and tomatoes. Adults require a daily intake of approximately 70 mg of Vitamin C, which can be easily obtained from a balanced diet that includes these foods. Unlike fat-soluble vitamins such as Vitamins A, D, E, and K, excess Vitamin C is not stored in the body but excreted through urine, requiring regular intake to maintain optimal levels. The discovery of Vitamin C's benefits, especially in preventing scurvy, is attributed to the 18th-century Scottish surgeon James Lind, a significant figure in the history of nutrition.
