Aronia Berries Regulate Blood Sugar Levels, U.S. Study Finds

Berries from the genus Aronia, commonly known as black chokeberry, are native to North America and have garnered attention for their high polyphenolic compound content.

These compounds are linked to health benefits beyond basic nutrition, including antioxidant properties that help reduce inflammation, Jordan Joseph reported for Earth.com.

A recent study led by Dr. Stephanie M. G. Wilson of Montana State University investigated whether aronia juice could protect against diet-induced gut microbiome challenges.

The research focused on how bacteria in the digestive system respond when aronia berries are introduced, particularly under unhealthy dietary conditions that promote inflammation.

Using a mouse model with transplanted human gut microbiomes from donors with varying levels of inflammation, researchers found that aronia supplementation provided robust protection.

Dr. Wilson noted that the study revealed significant increases in Eggerthellaceae, a family of bacteria capable of processing polyphenols. Additionally, the study linked black chokeberry intake with improved gut barrier function and shifts in metabolites associated with a healthier microbiome.

The findings suggest that aronia-based products may help balance the digestive system during periods of dietary stress, such as prolonged consumption of high-fat or sugary foods.

Researchers also highlighted that individual microbiomes could affect how people adapt to specific dietary habits.

Beyond its antioxidant properties, aronia has been associated with improved glucose levels, heart health, and metabolic function, possibly due to the presence of anthocyanins and other phenolic substances.
