New Review Finds Wild Blueberries Support Heart and Gut Health

A newly published scientific review brings together decades of research examining how wild blueberries may influence cardiometabolic health. This area of health includes key measures such as blood vessel function, blood pressure, blood lipids (cholesterol and triglycerides), and blood sugar (glucose).

The review appears in Critical Reviews in Food Science and Nutrition and grew out of an expert symposium organized by the Wild Blueberry Association of North America (WBANA) in Bar Harbor, Maine. The symposium included twelve specialists representing nutrition, food science, dietetics, nutrition metabolism and physiology, cardiovascular and cognitive health, gut health and microbiology, and both preclinical and clinical research models. While participants received travel reimbursement to attend the meeting, no funding was provided for writing or developing the review itself.

Decades of clinical research under review

The paper evaluates 12 human clinical trials conducted over a span of 24 years across four countries that specifically investigated the cardiometabolic effects of wild blueberries. In addition, the authors reviewed dozens of related clinical, translational, and mechanistic studies involving wild blueberries, cultivated blueberries, and a wide range of cardiometabolic outcomes.
