This pungent little bulb is one of the best detoxing foods out there. It helps stimulate the liver into producing detoxification enzymes that help filter toxic residues from the digestive system. I recommend adding sliced or cooked garlic to a suitable dish, as this will help any detox diet.his pungent little bulb is one of the best detoxing foods out there.
