Rainbow peppers are beneficial due to their rich nutrient content, including vitamins, antioxidants, and fiber, which contribute to various health benefits. They are a good source of vitamins A and C, potassium, folic acid, and fiber. Different colors of peppers contain varying amounts of specific antioxidants, like beta-carotene (more abundant in red peppers) and lycopene (in red peppers), which support eye health, may reduce the risk of certain diseases, and improve overall health.
