Scientists have found that almonds keep blood vessels healthy, reduce high blood pressure and improve blood flow; reducing the risk of heart disease. In the study, participants ate 50 grams, about 54 almonds, a day for a month. At 6 calories per almond, a more reasonable approach may be to sprinkle a few slivered almonds on your salad, yogurt, sautéed vegetables, or entrée—you’re likely to reap some of the heart-healthy effects.
