A kidney bean is a type of legume that belongs to the Phaseolus vulgaris species, commonly cultivated for its edible seeds. The name "kidney bean" derives from the resemblance of the seeds to the shape and color of a human kidney. It is primarily grown in tropical and subtropical regions as an annual crop that thrives in warm climates.
Kidney beans have a distinctive elongated shape with a slightly curved side and a blunt end, giving them an appearance similar to a kidney. They possess a thin skin that encloses a firm, creamy-textured, and starchy flesh. Kidney beans are available in various color variations, with the most common being deep red, although there are also white, black, and striped varieties.
Nutritionally, kidney beans are highly regarded for their rich content in dietary fiber, protein, essential vitamins, and minerals. They are a valuable source of plant-based protein, especially for individuals following a vegetarian or vegan diet. Additionally, kidney beans provide essential nutrients like iron, folate, potassium, and magnesium.
In culinary applications, kidney beans are widely utilized in a variety of dishes across different cuisines. They are a staple ingredient in classic recipes such as chili con carne, bean salads, soups, stews, and rice dishes. Kidney beans possess a robust, earthy flavor that tends to absorb the flavors of complementary ingredients in a dish.
While kidney beans are a versatile and nutritious food source, it is important to note that they must be cooked properly to ensure they are safe for consumption. Raw or undercooked kidney beans contain a naturally occurring toxin called lectin, which can cause digestive upset if not adequately neutralized by cooking.
A sort of bean-so called from its shape.
