A University of Maine study is the first using rats to demonstrate a relationship between consumption of whole wild blueberries and calming stress-related reactions that can lead to high blood pressure.


The blueberry-chomping rats generated less force in their blood circulation in response to phenylephrine, a stress hormone, than did arteries in rats fed the same diet without blueberries, meaning their arteries remained relaxed under stressful conditions.


The two-year research project led by Dorothy Klimis-Zacas was funded in part by the Wild Blueberry Association of North America.
