Name a notable source of vitamin A.

Carrots are a well-known source of vitamin A, particularly in the form of beta-carotene, which is a plant pigment that the body can convert into vitamin A. This vitamin is essential for several functions, including vision, immune function, and skin health. The vibrant orange color of carrots is indicative of their high beta-carotene content, making them a staple food for promoting good vision and overall health.

While spinach and fish also provide vitamin A, they do so in different forms. Spinach contains vitamin A in the form of carotenoids, similar to carrots, but it’s not as prominent a source as carrots are known to be. Fish, particularly fatty fish like cod liver and salmon, offer vitamin A in the form of retinol, which is the active form utilized directly by the body. Bananas, on the other hand, contain very little vitamin A and are not considered a significant source of this nutrient. Thus, carrots stand out as a notable source of vitamin A in the context given.
