High Anthocyanin Intake and Heart Attack Risk Reduction

Updated: Feb 2

According to the CDC, heart disease is the leading cause of death in the United States (1 in 4 deaths). It’s also the leading cause of death for women in the United States (1 in 5 deaths), making it an important health issue (1).

This study from Cassidy et al. (2013), followed 93,600 women (25–42 years old) from the Nurses’ Health Study II over an 18-year period. The purpose of the study was to examine the relationship between anthocyanins and other flavonoids, and the risk of myocardial infarctions, also known as heart attacks (2).

Flavonoids, a diverse group of phytonutrients, are widely available in many plant-based foods including a variety of fruits and vegetables. Previous studies have shown that purple corn is high in anthocyanins, one of the many sub-classes of flavonoids (2).

The study concluded that a high intake of anthocyanins may reduce heart attack risk, predominantly in young women. The greatest reduction in heart attack risk was 32%. For every 15 mg increase in anthocyanin intake, the relative heart attack risk decreased by 17% (2).
