Pulses are defined by the Food and Agricultural Organization of the United Nations (FAO) as annual leguminous crops yielding from one to twelve grains or seeds of variable size, shape and color within a pod. Pulses are used for food and animal feed.
The term pulses, as used by the FAO, is reserved for crops harvested solely for the dry grain. This therefore excludes green beans and green peas, which are considered vegetable crops. Also excluded are crops that are mainly grown for oil extraction (oilseeds like soybeans and peanuts), and crops which are used exclusively for sowing (clovers, alfalfa).
India is both the world's largest producer and the world's largest importer of pulses.
Canada, Myanmar, Australia and the United States are significant exporters of pulses. These are the four most significant suppliers of India's imports, in that order.
The vast majority of leguminous crops grown in the United States are soybeans, used as livestock feed and for extraction of vegetable oil, and peanuts, neither of which is considered a pulse. Lentils are also considered pulses.
Classification of pulses
Variety of pulses
FAO recognizes 11 primary pulses.
Dry beans (Phaseolus spp. including several species now in Vigna)
Pulses are 20 to 25% protein by weight, which is double the protein content of wheat and three times that of rice. For this reason, pulses are sometimes called "poor man’s meat". While pulses are generally high in protein, and the digestibility of that protein is also high, they often are relatively poor in the essential amino acidmethionine. Grains (which are themselves deficient in lysine) are commonly consumed along with pulses to form a complete protein diet.
Health
Pulses have significant nutritional and health advantages for consumers.[1] They are the most important dietary predictor of survival in older people of different ethnicities,[2] and in the Seven Countries Study, legume consumption was highly correlated with a reduced mortality from coronary heart disease.[3]
