What is Cyanidin?
Cyanidin, a member of the anthocyanin family, is a natural plant pigment responsible for the red, purple, and blue hues seen in various fruits, vegetables, and flowers. Its chemical structure consists of a flavylium cation with two phenol rings and a positively charged oxygen atom. This compound is particularly abundant in foods like berries (e.g., blueberries, strawberries, blackberries), red grapes, cherries, and red cabbage, contributing not only to their vibrant coloration but also to their potential health benefits.
Research indicates that cyanidin possesses numerous beneficial properties, including antioxidant, anti-inflammatory, and anticancer activities. Additionally, it has been observed to enhance cognitive function while protecting against age-related ailments.
