Health Claim on Food Labels: POTASSIUM Do you read the labels on the food you buy? Have you noticed the health claim on the front of the package related to potassium? All health claims on food labels are regulated by the Food and Drug Administration. Every statement, phrase or symbol on a food label must be truthful and not misleading. Approved Health Claim on Foods FDA has approved the following health claim for food labels: "Diets containing foods that are good sources of potassium and low in sodium may reduce the risk of high blood pressure and stroke." To qualify for the new health claim, a food must have at least 350 milligrams of potassium and less than 140 milligrams of sodium per serving. The food must also be low in fat and cholesterol. Why do we need potassium? Potassium is a mineral that:
Diuretics and potassium Some diuretics deplete potassium; others have little effect on it. A normal diet may not provide enough potassium to make up for what is lost due to a diuretic. Making a special effort to include potassium-rich foods in your diet will help compensate for the losses. Your doctor may also prescribe a potassium supplement. This should be monitored closely. Too much potassium? Excess amounts are usually excreted and harmful effects are rare. If the excess cannot be excreted, it can cause heart problems. People with kidney problems may not be able to get rid of excess potassium and may be advised to limit intake. Foods high in potassium In general, fruits and vegetables are excellent sources of potassium. Along with other health benefits, their potassium content is another reason for eating at least five servings of fruits and vegetables a day. Fish, beans, and nuts are also good sources. So are milk and yogurt; they also supply calcium, another mineral that may protect against high blood pressure. More potassium is found in lean cuts of meat than in fatty cuts since it is concentrated in muscle tissue.
