Which of the following foods is considered a source of beta carotene?

Sweet potatoes are a well-known source of beta-carotene, which is a type of carotenoid and a precursor to vitamin A. Beta-carotene is responsible for the orange color found in many fruits and vegetables, and sweet potatoes are particularly rich in this nutrient. Consuming foods high in beta-carotene can provide various health benefits, including supporting vision health, boosting the immune system, and promoting skin health due to its role as an antioxidant.

In contrast, chicken, cereal grains, and fish do not contain significant amounts of beta-carotene. Chicken is primarily a source of protein and does not provide beta-carotene since it comes from animal sources. Cereal grains may contain some vitamins and minerals but are not noted for their beta-carotene content. Fish also does not offer beta-carotene and is more recognized for its omega-3 fatty acids and protein. Therefore, sweet potatoes stand out as a prime source of beta-carotene among these options.
