White bean varieties include cannellini, Great Northern, and navy beans, however their nutritional profiles are all quite similar.
Along with protein, beans have a high amount of fiber (usually 10-11g per 1/2 cup serving) that helps lower cholesterol and regulate blood sugar levels. The white beans have been shown to contain higher levels of calcium than dark beans. They also hold potassium, folate, vitamin C, and non-heme iron. Be sure to soak dry beans or rinse canned beans to eliminate the gas-producing sugars and any added sodium.
