Your food choices can significantly influence your cardiovascular health, and eating the right breads is a smart idea for protecting your heart. Whole-grain breads, such as whole wheat, whole rye and whole multigrain, may help reduce blood pressure if you eat them regularly. When buying bread, look for those labeled 100-percent whole grain or those with whole grain as the first ingredient. Some breads advertise whole-grain status but are made of mostly white, refined flour.
In a study published in the "American Journal of Clinical Nutrition" in 2010, researchers found that participants who ate three portions of whole grains per day experienced a significantly greater reduction in blood pressure after 12 weeks than those who did not eat whole grains. The difference was enough to reduce the risk of coronary artery disease and stroke by 15 percent to 25 percent, according to the study authors.
