The kidney bean is a variety of common bean, scientifically known as Phaseolus vulgaris. It is named for its shape, which resembles a human kidney. Kidney beans are typically red or white and are commonly used in various dishes, including chili, salads, and rice dishes. They are rich in protein, fiber, and essential nutrients, making them a popular choice for both vegetarian and non-vegetarian diets. These beans must be cooked properly, as raw or undercooked kidney beans contain toxins that can be harmful. Soaking the beans and boiling them for at least 10 minutes helps eliminate these toxins. Kidney beans are not only nutritious but also versatile, adding flavor and texture to many meals.
