Sodium and potassium
Sodium and potassium
Nearly all Americans eat too much salt. Most of the salt comes from eating processed foods (75 percent), or adding salt to food while cooking and using the salt shaker at meals (5 to 10 percent). On average, the more salt a person eats, the higher his or her blood pressure. Eating less salt is an important way to reduce the risk of high blood pressure, which may in turn reduce the risk of heart disease, stroke, congestive heart failure, and kidney damage. To reduce the amount of sodium in your diet, eat less processed food and use less salt while cooking and at the table.
Other lifestyle changes may prevent or delay having high blood pressure and may help lower elevated blood pressure. These include eating more potassium-rich foods, losing excess weight, being more physically active, reducing stress triggers, and eating a healthy diet. If you drink alcoholic beverages, do so in moderation.
Did you know that sodium and potassium both impact blood pressure? A diet rich in potassium helps to counterbalance some of sodium's harmful effects on blood pressure.
