Introduction to Lentils and Legumes

Lentils and legumes are among the oldest cultivated foods in human history, belonging to the Fabaceae family. These nutrient-dense plant foods have been a dietary staple across civilizations due to their long shelf life, adaptability, affordability, and exceptional nutrition.

Lentils are small, lens-shaped seeds, while legumes include a broader group such as beans, peas, chickpeas, and peanuts. Together, they form the backbone of many traditional diets—from Indian dals and Mediterranean chickpea dishes to Latin American bean stews.

Beyond culinary versatility, lentils and legumes are recognized globally as powerful plant-based protein sources that support heart health, digestion, blood sugar balance, and sustainable eating.
