Bean

A bean is the seed of plants in many genera of the legume family (Fabaceae) used as a vegetable for human consumption or animal feed. The seeds are sold fresh or preserved through drying (a ''pulse''). Beans have been cultivated since the seventh millenium BCE in Thailand, and since the second millennium BCE in Europe and in Peru. Most beans, with the exception of peas, are summer crops. As legumes, the plants fix nitrogen and form seeds with a high protein content. They are produced on a scale of millions of tons annually in many countries; India is the largest producer.

Dried beans are traditionally soaked and boiled, and used in traditional dishes throughout the world including salads, soups, and stews such as chili con carne. Some are processed into tofu; others are fermented to form tempeh. Guar beans are used for their gum. The unripe seedpods of some varieties are also eaten whole as green beans or ''edamame'' (immature soybean). Some types are sprouted to form beansprouts.

Many fully ripened beans contain toxins like phytohaemagglutinin and require cooking to make them safe to eat. Many species contain indigestible oligosaccharides that produce flatulence. Beans have traditionally been seen as a food of the poor. Provided by Wikipedia
