Separately, lemon or lime juice and olive oil have their health benefits. The juices are low in calories and good sources of vitamin C, while the oil is rich in vitamin E and heart-healthy fats. But when taken together with water, proponents claim that they help cleanse your liver. There's no evidence to support this liver-cleansing benefit, however.
About the Cleanse
The lemon or lime and olive oil cleanse is touted as helping rid both the liver and gallbladder of chemicals and germs. It's also reported to help prevent and treat illnesses, including liver cancer, according to the American Cancer Society. Proponents of the citrus juice and olive oil cleanse recommend you drink the mixture for at least two days, sometimes while fasting, once or twice a year to flush the liver. The cancer society reports the drink causes you to have several bowel movements.
Truth Behind the Cleanse
There is no scientific evidence to support the claims that drinking lemon or lime juice with olive oil mixed in water cleanses your liver, let alone cures diseases such as cancer, according to American Cancer Society. In fact, when in good health, your liver, along with your kidneys, naturally rids your body of toxic substances on its own and eliminates them through your urine, stool and sweat. Additionally, many of these types of cleanses can be dangerous to certain groups of people, including children and teens and people with chronic illnesses.
