Blueberries may help fight atherosclerosis, according to a study in laboratory mice.
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.
Lesion size, measured at two sites on aorta, was 39% and 58% less than that of lesions in mice whose diet did not contain blueberry powder.
The blueberry-spiked diet contained 1 percent blueberry powder, the equivalent of about a half-cup of fresh blueberries.
