Rats fed a powder made from tart cherries had a lower risk of heart disease than those on a diet that simulates how most Americans eat, according to a study from the University of Michigan.The work was funded by Cherry Marketing Institute, which was not directly involved in the project, according to a news release.The rats, which have been designed to be at risk of heart trouble, had lower cholesterol and inflammation when the powder was added to the high-fat, moderate carbohydrate diet all the animals in the study ate. They also had lower body fat and a decrease in belly fat, which has been found to be a greater indicator of heart disease.The researchers suggested cherry consumption could have an effect on important fat genes and genetic expression."Heart disease is the No. 1 killer of Americans today, so it's important we continue researching ways people can improve their diet to help reduce key risk factors," said study co-author Dr. Steven F. Bolling, a cardiac surgeon. "We know excess body fat increases the risk for heart disease. This research gives us one more support point suggesting that diet changes, such as including cherries, could potentially lower heart disease risk."Researchers said the animal study is encouraging and will lead to further clinical studies in humans to explore the link between diet, weight, inflammation and lowering heart disease risk.Tart cherries, frequently sold as dried, frozen or juice, contain powerful antioxidants known as anthocyanins, which provide the bright, rich red color. Studies suggest these colorful plant compounds may be responsible for cherries' anti-inflammatory properties and other health benefits.
