Things you'll learn along the way

• ✓Excess sodium (salt) intake causes the body to retain water, increasing blood volume and raising blood pressure. Most health guidelines recommend limiting sodium to less than 2,300 mg per day.
• ✓A heart attack occurs when a blood clot blocks blood flow in a coronary artery, depriving part of the heart muscle of oxygen. Without treatment, the affected tissue dies.
• ✓The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise per week (about 30 minutes, 5 days a week) for cardiovascular health.
