Pomegranate juice may improve blood flow to the heart in people with ischemic coronaryheart disease(CHD). In a study of 45 people with CHD and myocardial ischemia (in which not enough blood gets to the heart muscle), participants who drank about 8 fluid ounces of pomegranate juice daily for 3 months had less ischemia during astress test. Study participants who did not drink the juice, meanwhile, had evidence of more stressinduced ischemia. The study noted no negative effects to drinking pomegranate juice (even on blood sugar levels orbody weight). Lead researcher, Dean Ornish, MD, believes pomegranate juice may even be able to help prevent heart disease in people who do not already have it.
