The forgotten food when it comes to health and wellness are lentils and legumes. Lentils are a popular food in other countries, but many do not realize that this legume offers ample fiber, nutrients, and little calories. A one cup serving of cooked lentils contains about 18 grams of protein, with little to no fat when prepared in water. Lentils are a great midday option at lunch time and they can help to fill you up and keep you feeling full. You can add any of your favorite spices to flavor the lentils and consider adding them to a serving of rice.
