Pigeon peas are small, round to oval, mostly cherry-red colored seeds in the legume family. However, they come in other color variations like yellow, brown, variegated, etc. Pigeonpeas are thought to have originated in India where they recognized as red gram, and currently grown as pulse crop throughout the tropics and subtropics of Asia, and sub-Saharan Africa for their nutritious dry seeds.
Pigeon beans are high in carbohydrates, but they are also rich in fiber (both soluble and insoluble). Pigeon beans also do not contain sugar. Instead, they have slowly-digested carbohydrates and resistant starch. This means that the carbohydrates in black beans are slowly converted to glucose, and some are not digested at all.
