Lentils are a plentiful source of fiber, folic acid, and potassium. These nutrients all support heart health. According to the American Heart Association (AHA), increased fiber intake can reduce levels of low density lipoprotein (LDL) cholesterol, or bad cholesterol

Brown, green, yellow, red or black — lentils are low in calories, rich in iron and folate and an excellent source of protein. They pack health-promoting polyphenols and may reduce several heart disease risk factors. They're easily cooked in 5–20 minutes, which — like soaking — reduces their antinutrient content.
