Anthocyanins are a class of powerful antioxidants, the vibrant pigments found in red, purple and blue fruits and vegetables. They belong to a larger class of phytochemicals called flavonoids, which are known for their many health benefits. Flavonoids are abundant in all parts of the plant: fruits, seeds, shoots, flowers and leaves. In nature, anthocyanins act as protectors against oxidative stress and inflammation, which are key players in various chronic diseases. Anthocyanidins are mainly composed of benzene rings and indole rings, and have purple-black or blue-purple colors. Anthocyanidins contain multiple phenolic groups and aromatic rings in their structure, and have strong antioxidant effects, which can help protect cells from damage by free radicals. Anthocyanidins not only provide color for plants, but also have certain medicinal value, and are often used to treat inflammation and enhance immunity. Anthocyanins are classified as follows:
- Delphinidin
- Malvinin
- Pelargonin
- Peonidin
- Peunidin
Sources of Anthocyanins
Fruits, vegetables, and grains with red, purple, blue, or black hues tend to be rich in anthocyanins. Blueberries, blackberries, raspberries, and strawberries are good sources. Other foods rich in anthocyanins include:
- Fruits: black plums, blood oranges, cherries, black grapes, red grapes, pomegranates.
- Vegetables: potatoes, purple yams, blueberries, mangosteens, purple grapes.
- Beans and rice: black beans, black rice, black soybeans.
- Drinks: grape juice, wine, food additives.
"The best strategy is to incorporate anthocyanin-rich foods into your daily dietary pattern," Prescott said. "We know these foods are safe and can help improve your overall nutrition."
Benefits of Anthocyanins for Human Health

Dosage
Based on research recommendations, adults can get the best health benefits by consuming about 25-30 mg of anthocyanins per day.
