Anthocyanins are naturally occurring, water-soluble plant pigments belonging to the flavonoid family. They contribute many of the red, purple and blue colors found in fruits, vegetables, flowers and other plant tissues.
Chemically, anthocyanins are sugar-bound forms of compounds called anthocyanidins. The term commonly appears in nutrition, plant chemistry and wellness discussions, particularly when talking about deeply colored plant foods and their naturally occurring phytochemicals.
Where Anthocyanins Are Found
Anthocyanins occur in foods such as blueberries, blackberries, elderberries, red and purple grapes, red cabbage and other deeply colored fruits and vegetables.
Color alone does not prove that a food contains anthocyanins. Plants contain several different families of pigments, and the amount and type of anthocyanins present can vary with plant variety, growing conditions, ripeness, storage and processing.
Evidence & Research
Anthocyanins have been widely studied for their antioxidant activity and for their possible relationship to cardiovascular and metabolic health.
Human research has found associations between anthocyanin-rich diets and some measures of health, while clinical trials continue to investigate how anthocyanins and their metabolites behave in the body. Findings vary according to the food or extract studied, amount consumed, study population and outcome being measured.
Why Context Matters
Foods rich in anthocyanins also contain fiber, vitamins, minerals and many other plant compounds. A health effect associated with berries or other colorful plant foods cannot automatically be attributed to anthocyanins alone, and the presence of anthocyanins should not be interpreted as evidence that a food or supplement can prevent or treat disease.
