Carotenoids are natural pigments found in many fruits and vegetables, giving them vibrant colors like orange, yellow, and red. They are important for plant health, helping with photosynthesis and protecting against damage from sunlight. Common carotenoids include beta-carotene, lutein, and zeaxanthin, which are often found in foods like carrots, spinach, and sweet potatoes. In addition to their role in plants, carotenoids are beneficial for human health. They act as antioxidants, helping to protect cells from damage. Some carotenoids, such as beta-carotene, can be converted into vitamin A in the body, which is essential for vision and immune function.
