Overview

Bean is a common name for the edible seeds of several genera in the family Fabaceae, used worldwide as a staple source of protein, starch, and fiber. The term covers hundreds of varieties across species, from the common bean (Phaseolus vulgaris) to soybeans, chickpeas, fava beans, and mung beans. Flavor and texture vary widely by type: black beans are earthy and creamy, chickpeas are nutty and firm, and mung beans are mild and soft when cooked.

Origin and history

Beans were domesticated independently in multiple regions. The common bean (Phaseolus vulgaris) originated in Mesoamerica, where it was domesticated alongside maize and squash in the milpa system by roughly 5000–3500 BCE [2][3]. Fava beans (Vicia faba) were domesticated in the Near East around 6000 BCE, and soybeans (Glycine max) in East Asia by approximately 3000 BCE [4]. The Three Sisters agricultural system — maize, beans, and squash — was foundational to Mesoamerican civilizations, with beans fixing nitrogen in the soil that maize depletes [2]. After 1492, New World beans spread globally via Spanish and Portuguese trade routes, while Old World beans (fava, chickpea, lentil) had already been established across Europe, Africa, and Asia for millennia [4].

Varieties and aliases

  • Common bean (Phaseolus vulgaris): black bean, pinto bean, kidney bean, navy bean, cannellini, cranberry bean, flageolet
  • Soybean (Glycine max): edamame (immature green), dried soybean
  • Mung bean (Vigna radiata): green gram, moong; used whole, split (moong dal), or as bean sprouts
  • Chickpea (Cicer arietinum): garbanzo bean, ceci; desi (small, dark) and kabuli (large, light) types
  • Fava bean (Vicia faba): broad bean, horse bean
  • Adzuki bean (Vigna angularis): red bean, azuki
  • Lima bean (Phaseolus lunatus): butter bean
  • Black-eyed pea (Vigna unguiculata): cowpea, lobia
  • Pigeon pea (Cajanus cajan): toor dal, gandul

Culinary uses

Beans are prepared in nearly every culinary tradition. They are boiled, stewed, fried, fermented, ground into flour, or sprouted. In Mexican cuisine, black beans and pinto beans are refried (frijoles refritos), served whole in caldo, or mashed as a filling for tlacoyos [2]. In Filipino cooking, mung beans (monggo) are stewed with garlic and pork for a Friday Lenten dish, and fermented black beans (tausi) season fish and braised pork [1]. In Persian cuisine, chickpeas and white beans thicken ash-e reshteh and appear in khoresh. In Japanese cooking, soybeans become tofu, natto, miso, and edamame. In Vietnamese cooking, mung bean paste fills bánh chưng and bánh tét for Tết, and red kidney beans layer into chè ba màu. In Korean cuisine, soybeans are fermented into doenjang and ganjang, and soybean sprouts (kongnamul) are a ubiquitous banchan.

Cross-cuisine context

Beans are the most widely distributed protein-starch staple across the cuisines represented on this platform. The Mesoamerican milpa bean (Phaseolus vulgaris) has no direct analogue in East Asian cuisines, where the soybean (Glycine max) occupies a structurally similar but functionally distinct role — soybeans are rarely eaten whole as a side dish in the way black beans are in Mexico, but instead are processed into tofu, soy sauce, and fermented pastes [5]. Comparison-by-function: the refried bean of Mexican cuisine and the mashed mung bean of Filipino hopia fillings both use cooked, mashed legumes as a savory-sweet base, though the flavor profiles diverge (lard and epazote vs. sugar and coconut milk). In West Asian and Mediterranean cuisines, chickpeas and fava beans serve the same protein-stretching role as common beans in the Americas, appearing in dips (hummus, foul medames), soups, and stews [6].

Notes for cooks

  • Dried beans must be soaked before cooking to reduce cooking time and improve digestibility. A quick soak (boil 2 minutes, rest 1 hour) works as well as an overnight soak [5].
  • Canned beans are fully cooked and need only reheating. Rinse them to reduce sodium and remove the metallic canning liquid.
  • Undercooked kidney beans contain lectins (phytohaemagglutinin) that can cause food poisoning. Kidney beans must be boiled vigorously for at least 10 minutes before simmering [5].
