Simply stated, potassium is a mineral that’s classified as an electrolyte, because it’s highly reactive in water. When dissolved in water, potassium produces ions that are positively charged. This ability to conduct electricity is what makes it an integral part of our body’s ability to function properly. Its importance for our health cannot be emphasized enough. “Potassium helps with many processes in the body, including water regulation in and out of the cells, sending nerve signals, and controlling muscle contractions,” explains Amy Shapiro, MS, RD, CDN, and founder of Real Nutrition. “It also has been shown to help decrease high blood pressure, reduce the risk of stroke, and prevent kidney stones and osteoporosis. This is because it helps to prevent calcium from leaching out of the bones.” Everyone thinks of bananas when trying to consume adequate potassium, but a single banana contains just 9 percent of your daily potassium requirement. “There are so many other whole foods that are abundant with potassium,” explains Shapiro.
