The story
What makes it unique
Red lentils are hulled and split seeds of Lens culinaris, offering fast digestion and cooking times compared to whole legumes. They provide a high-protein, high-fiber macronutrient profile that promotes prolonged satiety and slow glucose release. The removal of the hull slightly reduces insoluble fiber compared to whole lentils but increases digestibility and reduces anti-nutrient load.
