Final answer:
The statement that citrus fruits like orange and lemon, as well as green leafy and yellow vegetables, are rich sources of Vitamin C is true. Vitamin C is a water-soluble vitamin essential for many body functions and found in a variety of fruits and vegetables.
Step-by-step explanation:
Foods rich in Vitamin C indeed include citrus fruits such as orange and lemon, as well as certain green leafy and yellow vegetables. This statement is true. Vitamin C, also known as ascorbic acid, serves several critical roles in the human body. It is an antioxidant, helps in the absorption of iron from the intestine, and can reduce the duration and severity of the common cold.
Citrus fruits are not the only sources of Vitamin C. In addition to oranges and lemons, Vitamin C can also be found in other fruits like guavas, berries, and melons as well as vegetables such as cabbage, lettuce, and tomatoes. A daily intake of Vitamin C is essential, with recommended amounts being 30 mg for infants and 70 mg for adults.
Unfortunately, there is a common misconception that Vitamin B and C are fat-soluble. It is important to clarify that Vitamin C is in fact a water-soluble vitamin and is crucial for immune function and skin health. Historically, a lack of Vitamin C in the diet led to scurvy, a disease famously prevented by the inclusion of citrus fruits in sailors' diets.
