    "definition": "The broad bean or fava bean, Vicia faba, an annual legume domesticated in the Near East by around 10,000 years ago, grown for large edible seeds eaten fresh from the pod or dried, used in dishes such as ful medames and falafel in Egypt, and as fodder and a nitrogen-fixing cover crop; the registry aliases include the broad bean pod and the Fava di Leonforte, a traditional Sicilian variety. Eating fava beans can trigger acute haemolytic anaemia, called favism, in people with G6PD deficiency, a common inherited enzyme deficiency, and sudden dark urine, jaundice or pallor after eating them needs urgent medical care.",
