'''''Vicia faba''''', the '''broad bean''', '''fava bean''', '''faba bean''', '''horse bean''', '''field bean''' or '''tic bean''' is a species of [[legume|bean]] ([[Fabaceae]]) native to north [[Africa]] and southwest [[Asia]], and extensively cultivated elsewhere. Although usually classified in the same genus ''[[Vicia]]'' as the [[Vicia|vetches]], some botanists treat it in a separate monotypic genus as ''Faba sativa'' Moench.
[[Image:Tuinboon zaden in peul.jpg|left|thumb|Broad beans in the pod]]
It is a rigid, erect plant 0.5-1.7 m tall, with stout stems with a square cross-section. The [[leaf|leaves]] are 10-25 cm long, pinnate with 2-7 leaflets, and of a distinct glaucous grey-green colour; unlike most other vetches, the leaves do not have tendrils for climbing over other vegetation. The [[flower]]s are 1-2.5 cm long, with five petals, the standard petal white, the wing petals white with a black spot (true black, not deep purple or blue as is the case in many "black" colourings [http://chla.library.cornell.edu/cgi/t/text/pageviewer-idx?sid=75ed643231a8cab76743747215fd6ab6&idno=2731628&c=chla&cc=chla&q1=Cheiranthus&seq=51&view=image]), and the keel petals white. The [[fruit]] is a broad leathery pod, green maturing blackish-brown, with a densely downy surface; in the wild species, the pods are 5-10 cm long and 1 cm diameter, but many modern [[cultivar]]s developed for food use have pods 15-25 cm long and 2-3 cm thick. Each pod contains 3-8 [[seed]]s; round to oval and 5-10 mm diameter in the wild plant, usually flattened and up to 20-25 mm long, 15 mm broad and 5-10 mm thick in food cultivars. Vicia faba has a diploid (2n) chromosome number of 12, meaning that each cell in the plant has 12 chromosomes (6 homologous pairs). Five pairs are [[acrocentric]] chromosomes and 1 pair is [[metacentric]].
==Cultivation and uses==
Broad beans have a long tradition of cultivation in [[Old World]] [[agriculture]], being among the most ancient plants in cultivation and also among the easiest to grow. It is believed that along with [[lentil]]s, [[peas]], and [[chickpea]]s, they became part of the eastern [[Mediterranean]] diet in around [[6000 BC]] or earlier. They are still often grown as a [[cover crop]] to prevent [[erosion]] because they can over-winter and because as a [[legume]], they fix [[nitrogen]] in the soil.
[[Image:Tuinboon voor zaad.jpg|left|thumb|Mature field bean pods]]
In much of the [[Anglophone]] world, the name '''broad bean''' is used for the large-seeded cultivars grown for human food, while '''horse bean''' and '''field bean''' refer to cultivars with smaller, harder seeds (more like the wild species) used for animal feed, though their stronger flavour is preferred in some human food recipes, such as [[falafel]]. The term '''fava bean''' (from the [[Italian language|Italian]] name ''fava'') is commonly used in the United States (especially for beans grown for human consumption), but is also seen elsewhere, especially in Mediterranean recipes (this language shift can also be seen in the common use of the term "[[arugula]]" in the US for what in the UK is called "rocket").
==Culinary uses==
[[Image:Broad-beans-after-cooking.jpg|thumb|right|250px|Broad beans, shelled and lightly steamed for 3 minutes.]]
Broad beans are eaten while still young and tender, enabling harvesting to begin as early as the middle of spring for plants started under glass or over-wintered in a protected location, but even the maincrop sown in early spring will be ready from mid to late summer. Horse beans, left to mature fully, are usual
ly harvested in the late autumn.
The beans can be fried, causing the skin to split open, and then salted to produce a crunchy snack. These are popular in China, and also in Thailand where their name means "open-mouth nut".
In the [[Sichuan cuisine]] of [[China]], broad beans are combined with [[soybean]]s and [[chili peppers]] to produce a spicy fermented bean paste called ''[[doubanjiang]]''.
In most Arab countries the fava bean is used for a breakfast meal called [[ful medames]]. Ful medames is usually crushed fava beans in a sauce although the Fava beans do not have to be crushed.
==Health issues==
Broad beans are rich in [[tyramine]], and thus should be avoided by those taking [[monoamine oxidase inhibitor|monoamine oxidase (MAOI) inhibitor]]s.
Raw broad beans contain [[vicine]] and [[convicine]], which can induce [[hemolytic anemia]] in patients with the hereditary condition [[glucose-6-phosphate dehydrogenase deficiency]] (G6PDD). This potentially fatal condition, which is quite common in certain ethnic groups, is called "favism" after the fava bean.<ref>{{cite web | url=http://www.scienzavegetariana.it/nutrizione/favabeans.html | title=Fava Beans, Levodopa, and Parkinson's Disease | author=Kathrynne Holden}}</ref><ref>{{cite web | url=http://archive.southcoasttoday.com/daily/05-96/05-29-96/c01li096.htm | author=Russ Parsons | title=The Long History of the Mysterious Fava Bean}}</ref>
Broad beans are rich in [[levodopa|L-dopa]], a substance used medically in the treatment of [[Parkinson's disease]]. L-dopa is also a natriuretic agent, which might help in controlling [[hypertension]].<ref>Vered Y, Grosskopf I, Palevitch D, Harsat A, Charach G, Weintraub MS, Graff E.

==Other uses==
* In ancient [[Greece]] and [[Rome]], beans were used in voting; a white bean being used to cast a ''yes'' vote, and a black bean for ''no''.
* In [[Ubykh people|Ubykh]] culture, throwing beans on the ground and interpreting the pattern in which they fall was a common method of divination ([[favomancy]]), and the word for "bean-thrower" in that language has become a generic term for seers and soothsayers in general.
* In [[Italy]], broad beans are traditionally sown on [[November 2]], [[All Souls Day]]. Small cakes made in the shape of broad beans (though not of them) are known as ''fave dei morti'' or "beans of the dead". According to tradition, [[Sicily]] once experienced a failure of all crops other than the beans; the beans kept the population from starvation, and thanks were given to [[Saint Joseph]]. Broad beans subsequently became traditional on [[Saint Joseph's Day]] altars in many Italian communities. Some people carry a broad bean for good [[luck]]; some believe that if one carries a broad bean, one will never be without the essentials of life. In [[Rome]], on the first of May Roman families traditionally eat fresh fava beans with [[Pecorino Romano]] cheese during a daily excursion in the [[Roman Campagna|Campagna]].
* In ancient [[Greece]] and [[Rome]], beans were used as a food for the dead, such as during the annual [[Feast of the Lemures|Lemuria]] festival. In some folk legends, such as in [[Estonia]] and the common [[Jack and the Beanstalk]] story, magical beans grow tall enough to bring the hero to the clouds. The [[Grimm Brothers]] collected a story in which a bean splits its sides laughing at the failure of others. Dreaming of a bean is sometimes said to be a sign of impending conflict, though others said that they caused bad dreams. [[Pliny the Elder|Pliny]] claimed that they acted as a [[laxative]]. European folklore also claims that planting beans on [
[Good Friday]] or during the night brings good luck.

* In the film ''[[The Silence of the Lambs (film)|The Silence of the Lambs]]'', [[Hannibal Lecter]] mentions that he once ate the liver of a census taker "with some fava beans and a nice [[Chianti]]."
