Admit it: Incorporating more potassium into your diet isn't at the top of your priorities. (That is until you're in the middle of a cramp, in which case you reach for a banana.) Although, there many reasons you should start reaching for potassium-rich foods aside from their cramp-curing qualities. In fact, this mineral is crucial to our body's functions and helps to maintain the health of our cells and organs. "Because this nutrient is under-consumed, it's a public health concern in the United States," says registered dietitian nutritionist Maya Feller, MS, RD, CDN. The 2015–2020 U.S. Dietary Guidelines for Americans recommends 4700 mg of potassium each day although a study found that the average American woman gets only half of the recommended intake.
The recommended amount supports fluid balance, bone health, cardiovascular and digestive health, and muscular function. The problem is that many American diets are high in refined grains, processed meats, and sugary beverages, says Feller. "This pattern of eating is not in line with consuming minimally processed vegetables, fruit, and whole grains—which are potassium-rich," she says. Some symptoms of a potassium deficiency (aka hypokalemia) are constipation, fatigue, irregular heartbeat, tingling, and numbness. But avoiding these conditions is easier than you may think. All you have to do is focus on basics foods that give you more of the nutrients you need.
