Believed to have originated in Mexico and south-western areas of the United States, Hopi Red lima beans have an almost nutty taste that makes them quite perfect for chili and other Hispanic dishes. And because they are very high in protein, these beans are a wonderful alternative to meat. In addition, one cup of lima beans contains 25 percent of an adult’s iron needs. It is worth noting that Iron plays a significant role in the production of red blood cells, not to mention that it also helps your body produce energy.
