A Review of the Properties of Anthocyanins and Their Influence on Factors Affecting Cardiometabolic and Cognitive Health

The incidence of cardiovascular and metabolic diseases has increased over the last decades and is an important cause of death worldwide. An upcoming ingredient on the nutraceutical market are anthocyanins, a flavonoid subgroup, abundant mostly in berries and fruits. Epidemiological studies have suggested an association between anthocyanin intake and improved cardiovascular risk, type 2 diabetes and myocardial infarct. Clinical studies using anthocyanins have shown a significant decrease in inflammation markers and oxidative stress, a beneficial effect on vascular function and hyperlipidemia by decreasing low-density lipoprotein and increasing high-density lipoprotein. They have also shown a potential effect on glucose homeostasis and cognitive decline. This review summarizes the effects of anthocyanins in in-vitro, animal and human studies to give an overview of their application in medical prevention or as a dietary supplement.

Automated summary

Anthocyanins, a subgroup of flavonoids found mostly in berries and fruits, have shown potential benefits in improving cardiovascular risk, type 2 diabetes, and myocardial infarct. Clinical studies have demonstrated their ability to decrease inflammation and oxidative stress, improve vascular function, and have a positive effect on hyperlipidemia. Additionally, anthocyanins may also have an impact on glucose homeostasis and cognitive decline.
