legumes and lentils nutritional facts

Nutritional facts of lentils

Lentils contain 3 of the most important nutrients you will need for your training: a lot of fiber, protein, and slow-digesting carbohydrates.

A cup of lentils contains only 230 calories, with an impressive 18 grams of protein, and a total of 16 grams of fiber.


Adults generally need 10 to 35 percent of their total daily calories from proteins. This amounts to about 50-175 grams of protein a day based on a 2,000-calorie-a-day diet (according to Mayo Clinic).

As per the U.S. Department of Agriculture National Nutrient Database for Standard Reference, 1 cup of cooked legumes/lentils contains about 18 grams of protein. So with some clever permutations and combinations, it should be possible to get all your protein needs from legumes, lentils, and dairy products.

Meat eaters, however, will point out that legumes/lentils do not contain all nine essential amino acids. For that reason we cannot consider them as a complete source of proteins. They basically lack the amino acids methionine and cysteine. The good news, however, is that you can easily get all nine amino acids by consuming legumes/lentils with a grain such as rice.

types of lentils


Though different types of lentils may vary slightly in their nutrient contents, one cup (198 grams) of cooked lentils generally provides about 38 grams of carbohydrates (with fibers making almost 42%).

One cup of cooked red lentils provides almost 62% of the daily dietary fiber requirement for adults (15.6 g), which is the highest among all high-fiber foods such as chickpeas, kidney beans, and whole wheat bread. Split red lentil also has the lowest glycemic index (GI) when compared with rice and white bread, which makes the lentil an ideal food for people with diabetes.


There is almost no fat in lentils, which makes them a naturally fat-free food. However, many cooks add fat such as olive oil when they cook lentils, and that will change the nutrition facts. One-cup serving of lentils contains less than 1 gram of fat (0.8 grams).

Vitamins & minerals
