Lentils are a powerhouse for anyone looking to manage blood sugar. Rich in both soluble fiber and plant-based protein, they digest slowly—meaning they don’t cause the sharp blood glucose spikes often triggered by refined carbs. Soluble fiber helps trap sugars and slow their absorption, while protein supports steady energy. Lentils are also high in resistant starch, a type of carbohydrate that feeds healthy gut bacteria and contributes to improved insulin sensitivity. Add them to hearty soups, stews, curries, or cold grain bowls. They’re affordable, shelf-stable, and deeply satisfying—a true pantry staple for blood sugar balance.
