Benefits of Olive Oil & Lemon Juice

People believe that olive oil and lemon juice together can have the following health benefits-

Lower gallstones and kidney stones risk

  • Our diet plays a significant role in forming kidney stones and gallstones.
  • People who take high amounts of saturated fat and inadequate vitamin C can lead to kidney and gall bladder stone formation. Gallstones are solid deposits of cholesterol and bilirubin that appear in the gall bladder.
  • Some informal studies claim that lemon juice and olive oil can act as a greasy substance and move the gallstone out of the body. However, there is no scientific evidence to confirm the claim.
  • Some research suggests that consuming healthy fats, viz, olive oil, can avoid gallstone formation by vacating the gall bladder as needed.
  • Deficiency of vitamin C can lead to gallstone formation. Our body’s vitamin C works by preventing cholesterol solidification and helps convert it into bile acids. It thus helps prevent gallstone formation.
  • A research study has found that an increase of vitamin C by 27 micromoles per liter leads to decreased gallstone formation in women 4 Benefits| Researched based study from National Library of Medicine . However, new studies are warranted to establish this fact.

Detoxifies the body

  • Research study on the consumption of olive oil compared to other plant-based oils found that people who took olive oil had lower levels of bad cholesterol (low-density lipoprotein) and higher amounts of good cholesterol (high-density lipoprotein).
  • The antioxidants in lemon juice and olive oil might act as cleansing agents to detoxify the body and prevent infections 5 Benefits| Researched based study from National Library of Medicine . However, additional studies are needed to validate the combination in detoxifying the body.

Olive oil and lemon juice for weight loss

  • Studies have shown that monounsaturated fatty acid in olive oil and vitamin C in lemon juice play a vital role in losing weight.
  • In our body, vitamin C is very essential for carnitine production. Carnitine transports fat molecules into cells and breaks them into energy. Thus, insufficient vitamin C can lead to decreased fat breakdown.
  • One study found that people with low vitamin C burned less fat than people exercising regularly and with adequate vitamin C.
  • In another animal study, mice fed with vitamin C and a high-fat diet gained less body fat than mice without a high-fat diet 6 Benefits| Researched based study from National Library of Medicine.
