Carotenoids are a group of natural pigments that give yellow, orange, and red color to many fruits, vegetables, and other plants. They play an important role in photosynthesis, protecting plants from damage caused by sunlight and are involved in the conversion of light energy. The main carotenoids found in foods include beta-carotene, lycopene, lutein, and zeaxanthin.

Carotenoids are important for human health due to their antioxidant properties. They protect cells from oxidative stress, reducing the risk of developing cardiovascular disease, certain cancers, and eye diseases such as age-related macular degeneration. Beta-carotene, for example, is provitamin A, meaning it is converted in the body into vitamin A, which is essential for healthy skin, vision, and the immune system.

Carotenoids are also found in many vegetables and fruits, such as carrots, pumpkins, tomatoes, spinach, and bell peppers. Regular consumption of foods rich in carotenoids contributes to the overall promotion of health and protection of the body from chronic diseases.
