Can you rinse the salt off canned beans?
Salt is used by food manufacturers to enhance flavor—we've seen more than 500mg in just ½ cup of beans. That's why we call for canned beans to be rinsed and drained before preparing.
THE TEST: We rinsed, drained, and then tested two varieties of beans and compared them with their unwashed counterparts.
THE RESULTS: Black Beans: Sodium in ½ cup: 424mg; Sodium in ½ cup, rinsed and drained: 232mg; Red Kidney Beans: Sodium in ½ cup: 260mg; Sodium in ½ cup, rinsed and drained: 148mg
Bottom line: The beans lose more than 40% of their sodium when rinsed and drained.
