Lentils are a nutritious and versatile legume used in many different dishes. There are different types of lentils, including green, brown, and red varieties. Lentils are an excellent source of plant-based protein, fiber, and essential vitamins and minerals. Lentils also have a low glycemic index (GI). 

The low GI of lentils can help regulate blood sugar levels and keep energy levels stable throughout the day. This article will discuss the glycemic index of lentils, how they affect blood sugar, and the benefits of eating lentils. Whether you’re following a vegetarian or vegan diet or just looking to add more plant-based foods to your meals, lentils are a versatile and affordable option for doing so.

Types of Lentils

There are many different kinds of lentils to choose from, each with a unique flavor and texture. The nutrition each type provides may vary slightly, but they’re all pretty similar. Here are some of the most common types of lentils:

Green lentils

Green lentils are the most widely available. They have a mild, earthy flavor and hold their shape well when cooked, making them a great choice for salads and stews.

Red lentils

Red lentils have a slightly sweet, nutty flavor and cook down to a soft, creamy texture. They are commonly used in Indian and Middle Eastern cuisine for dishes like dhal and soups.

French lentils

French lentils may sometimes be called Puy lentils. These small, dark green lentils have a nutty flavor and hold their shape well when cooked. They are often used in salads and side dishes.

Brown lentils

Brown lentils share a similar taste and texture with green lentils, but they are slightly smaller and don’t take as long to cook. They are often used as a meat substitute in soups, stews, and vegetarian dishes.

All types of lentils offer several health benefits and make a delicious, high-protein, high-fiber addition to any diet.

Glycemic Index and Load of Lentils

The glycemic index (GI) tells you how quickly food raises blood sugar levels. The glycemic load (GL), on the other hand, considers both the GI and the number of carbohydrates in a serving of food. Low GI foods help manage blood glucose levels, especially when combined with high GI foods. 

Lentils have a low GI and a low GL, so they are digested slowly, and the body’s glycemic response is minimal. This means that lentils do not cause a rapid spike in blood glucose levels. 

The GI of a serving size of lentils ranges from 18 to 36, depending on the type of lentil and how it is prepared. Boiled red lentils often have a lower GI, while canned green lentils have a higher GI. Lentils have a low GL of 5. This makes lentils a great choice for those looking to regulate their blood sugar levels and maintain a healthy weight.^1,2,3

Other low-glycemic legumes include chickpeas, kidney beans, black beans, and peas.
