Why Are Legumes Called Pulses? Discover the Origin!

Legumes and pulses are terms often used interchangeably, but they have distinct meanings that trace back to historical, botanical, and culinary contexts. Understanding why legumes are called pulses requires exploring their definitions, origins, and uses.

What Are Legumes?

Legumes are plants in the family Fabaceae (or Leguminosae) that produce seeds in pods. This family includes a wide variety of plants such as beans, lentils, peas, chickpeas, soybeans, and peanuts. Legumes are valued for their ability to fix nitrogen in the soil, improving soil fertility naturally.

Defining Pulses

Pulses are a subset of legumes. Specifically, pulses refer to the dry, edible seeds of leguminous plants. Common pulses include dried beans, lentils, chickpeas, and dry peas. Unlike fresh peas or green beans, pulses are harvested solely for their dry seeds.

Botanical and Culinary Distinctions

• Legumes: The broader category including all plants in the Fabaceae family, encompassing fresh vegetables (like green beans and fresh peas), oilseeds (like soybeans and peanuts), and pulses.
• Pulses: The dry seeds harvested from leguminous plants, excluding those used for oil extraction or as fresh vegetables.

Origin of the Term "Pulse"

The word "pulse" comes from the Latin word puls, meaning thick soup or porridge made from boiled legumes. This term was adopted into English to describe the dry seeds used primarily for cooking hearty dishes.

Nutritional Importance of Pulses

Pulses are rich in protein, fiber, vitamins, and minerals, making them a staple in vegetarian and vegan diets worldwide. They are low in fat and have a low glycemic index, contributing to heart health and blood sugar regulation.

Why the Distinction Matters

Understanding the difference between legumes and pulses helps in agriculture, nutrition, and culinary arts. For example, pulses are often promoted for their sustainability and health benefits, while legumes as a whole include a broader range of plants with diverse uses.
