The fava bean is the edible seed of *Vicia faba*, a legume also known as broad bean or faba bean. It is grown and eaten worldwide as a food crop, and the plant is also used as fodder and a cover crop.

What it is

Fava beans are large, flat seeds that grow in pods on *Vicia faba*, a plant in the pea and bean family (Fabaceae). They are pale green to whitish when fresh and are used as a vegetable or dried pulse. The term "fava bean" is often used interchangeably with "broad bean."

Why it matters

Fava beans are a nutrient-dense legume, providing protein, fibre, and several vitamins and minerals. They are a common plant-based ingredient in many cuisines. However, some people with glucose-6-phosphate dehydrogenase deficiency can develop favism—a serious hemolytic reaction—after eating them.

Key details

Fava beans can be eaten raw, blanched, cooked, or dried and rehydrated. The tough outer skin is often removed before cooking. In Canada, they are used in home gardens and cooking, especially in immigrant cuisines and seasonal markets, and are grown as a cool-season crop.
