Seasoning your food with herbs and spices might do more than make your food taste better. It might improve your health. In a new study from the American Society for Nutrition, researchers at Oxford and Penn State University found that adults who seasoned foods with just over one teaspoon of herbs and spices was associated with lower blood pressure after four weeks. Simply switching from using herbs and spices instead of salt to add flavor to your meals might be a simple way to help improve your heart health.
