4. Lentils
A rich source of dietary fiber, which aids in digestion and therefore cleanses the liver, lentils are a great food to consume if you are looking to cleanse and improve the function of this organ. Lentils also contain plant-based protein, which is much better for your liver than animal-based proteins.
Protein that is derived from animals can be hard on the liver, which can actually cause damage. Lentils, on the other hand, provide necessary protein without causing damage to this vital organ.
