English: Black turtle bean
Scientific Name: Phaseolus vulgaris
Black turtle bean, also known as black bean, is a small, shiny, black-colored bean commonly used in Latin American cuisine. It is a variety of the common bean (phaseolus vulgaris) and is native to the Americas, where it has been cultivated for thousands of years.
Black turtle beans are a good source of protein, fiber, and various vitamins and minerals, including iron, magnesium, and folate. They are often used in dishes such as soups, stews, and salads, and are a key ingredient in many traditional Latin American dishes, such as black bean soup, frijoles negros, and gallo pinto.
In addition to their culinary uses, black turtle beans have also been studied for their potential health benefits. Some research suggests that consuming black beans may help to reduce the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. This may be due in part to their high fiber and antioxidant content.
