Fava beans are the dried beans of the Vicia faba species of the legume family. They're the same species as the fresh or frozen green broad beans more familiar in British cooking but fava beans are the fully mature dried fruit of smaller seeded varieties. Fava beans are loaded with nutrients and may offer impressive health benefits. Eating these beans regularly may have benefits for symptoms of Parkinson's disease, help prevent birth defects, boost immunity, aid weight loss and lower cholesterol levels and blood pressure
