Ba­nanas are great for de­hy­dra­tion cramps.

Men's Health (Australia) - - ADVANTAGE -

True, but there’s noth­ing mag­i­cal about ba­nanas. The potas­sium in ba­nanas may be key. Potas­sium, an­other elec­trolyte, helps blunt the ef­fects of sodium and, with help from your kid­neys, moves it out of your body. Think of sodium and potas­sium on op­po­site sides of a see­saw, work­ing to balance each other to achieve proper hy­dra­tion. Most peo­ple get around half the rec­om­mended 4,700 mil­ligrams of potas­sium daily, says Megan Meyer, of the In­ter­na­tional Food In­for­ma­tion Coun­cil Foun­da­tion. Im­bal­ance can also af­fect blood pres­sure and heart con­trac­tions.
