The research provides the first direct evidence that blueberries can help prevent harmful plaques or lesions, symptomatic of atherosclerosis, from increasing in size in arteries.

Principal investigator Xianli Wu, based in Little Rock, Ark., with the USDA Agricultural Research Service (ARS) Arkansas Children’s Nutrition Center and with the University of Arkansas for Medical Sciences, led the investigation. The findings are reported in the current issue of the Journal of Nutrition.

Atherosclerosis is the leading cause of two forms of cardiovascular disease–heart attacks and strokes. Cardiovascular disease is the number one killer of Americans.

The study compared the size, or area, of atherosclerotic lesions in 30 young laboratory mice. Half of the animals were fed diets spiked with freeze-dried blueberry powder for 20 weeks; the diet of the other mice did not contain the berry powder.
