Developed and released in 1991, Norstar is a medium, early-maturing navy bean with a wide set of culinary uses and health benefits. For one, it containns magnesium and folate, both of which work together to keep the heart strong and protected. Folate, for instance, decreases levels of homocysteine, thereby preventing heart attacks and strokes with the help of magnesium. In addition, navy beans in general have the ability to promote healthy circulation, reduce the risk of cancer, stimulate growth, and lower diabetes risk.
