Lentils are a type of legume (such as pinto and kidney beans) which have the advantage of being much more quick-cooking than other dried beans, and do not have to be soaked ahead of time. They come in many colors -- although the most common ones are green or brown, you can find pink ones (which cook the fastest, but don't hold their shape), yellow ones, and black ones. They generally have a low glycemic index due to the high amounts of slowly-digested starch and resistant starch they contain. (For more information about these special types of starches see under "Health Benefits" below.) Lentils are also high in fiber, and legumes such as lentils have more protein than almost any other plant source.

Glycemic Index for Lentils

There have been quite a number of glycemic index studies for lentils, the averages of which tend to be around 30, which is very low due to the slowly digested and resistant starch in lentils. The exception was a study of canned lentils, which was 52. (Studies of canned beans (as well as those cooked in a pressure cooker) always show them to have a higher glycemic index than dried beans which are soaked and boiled.)

Health Benefits of Lentils

Lentils are an excellent source of fiber, folate and manganese, a very good source of iron, and a good source of copper and thiamin.

Lentils, like other legumes, are perhaps the best food source of slowly-digested carbohydrate and resistant starch. Essentially, this means that they contain starch which is slowly converted to glucose, and starch which is not digested in the small intestine at all. At least one study has shown that replacing more rapidly-digested carbohydrates with legumes improved glycemic control in diabetics. Consuming foods high in resistant starch may also improve colon health, including promoting healthy bowel flora. Resistant starch may even improve insulin sensitivity and absorbtion of minerals such as calcium. Note though, that canned beans have a higher glycemic index, and less slowly-digested and resistant starch than dried beans which are cooked home. Also, some diabetics note that lentils and beans raise cause a rapid rise of blood glucose, so there is clearly a lot of individual variation in how our digestive systems handle legumes.
