What Counteracts Sodium?

Electrolyte Activity

Sodium and potassium work together to control the balance of fluids and minerals in and around every cell of your body. Most of the work done by sodium takes place outside cell walls, whereas potassium carries out most of its work inside cells. This important balancing act helps regulate blood pressure and support normal nerve, muscle and organ function. A high-sodium diet can cause you to retain fluids, which can ultimately lead to high blood pressure. Potassium helps your body excrete excess sodium through urine.

Sodium Intake

The American Dietetic Association estimates that most people in the United States get about 3,400 milligrams of sodium a day, and that roughly 80 percent of this amount comes from processed foods. U.S. Dietary Guidelines suggest that if you’re healthy and under the age of 50, you should generally keep your sodium intake under 2,300 milligrams a day. Older adults, African Americans and individuals with high blood pressure, kidney disease or diabetes are advised to limit their sodium intake to 1,500 milligrams a day. According to the American Heart Association, all adults should keep their daily sodium intake below 1,500 milligrams.

Potassium Intake

Since fruits and vegetables aren’t a major part of the standard American diet, it comes as no surprise that Americans generally don’t get enough potassium. According to the Linus Pauling Institute at Oregon University, most women in the United States consume just 2,300 milligrams of potassium a day, while the average intake for men isn’t much higher. Dietary guidelines recommend that all healthy adults get at least 4,700 milligrams of potassium a day. At this intake level, potassium has been found to diminish the effects of sodium, reduce high blood pressure and protect against osteoporosis and kidney stones.

Considerations

Prunes, raisins, bananas, dark leafy greens, dried beans and peas, lentils, tomatoes, potatoes, sweet potatoes, yogurt and fish are some of the best sources of potassium. Because it’s not a heat-sensitive nutrient, cooked foods are generally higher in potassium than their raw counterparts – a cup of tomato sauce is significantly higher in potassium than a cup of chopped tomato, just as cooked spinach delivers more potassium than the raw variety. Boost your potassium intake with unprocessed foods whenever possible so you don’t inadvertently increase your sodium intake. Dried beans are high in potassium and virtually sodium-free, while the canned variety is high in potassium as well as sodium.
