Mice fed a diet rich in vegetables were less likely to develop atherosclerosis, fatty deposits in the arteries that can lead to heart attack and stroke.
In the study, researchers from Wake Forest University School of Medicine used mice specially bred to develop atherosclerosis. Half were fed a diet with no vegetables and the other half were fed a vegetable-rich diet, including broccoli, green beans, corn, peas and carrots.
Sixteen weeks later, mice fed vegetables had 38 percent less buildup of fatty plaques in their arteries, along with a reduction in total cholesterol and body weight.
Further, mice that ate a vegetable-rich diet had a 37 percent reduction in a marker of inflammation called serum amyloid, which suggests the vegetables may fight inflammation. (Inflammation in the arteries is linked to atherosclerosis.)
Although it's not known whether these results hold true for humans as well, it is known that fruits and vegetables fight heart disease in humans. However, on average most people only eat three out of the five (minimum) recommended servings of fruits and vegetables a day.
