Heart Health Tips

  • Have a sense of humor! A good laugh can send up to 20 percent more blood pumping through the body.
  • Eat a diet low in these three nutrients: fat, cholesterol, and salt. They contribute to high cholesterol and blood pressure.
  • Eat chocolate. Indulging regularly could reduce your risk for heart attack by roughly 37 percent. Just keep the chocolate dark (more antioxidants) and the portion small (one ounce).
  • Check sodium labels, and aim for less than 2,000 mg per day. A high salt diet significantly raises the risk of heart disease.
  • Get moving to avoid heart disease. For every minute you walk, your life is extended by 1.5 to two minutes.
