Lemon juice contains antioxidants that help fight off the common cold, flu, and cancer, according to Medical News Today. It also helps reduce fluid retention, pain and swelling, and promotes a healthy complexion.
Lemon juice is a good digestive aid, notes Cleveland Clinic. It contains citric acid, a natural preservative that helps the body break down carbohydrates. The acid slows carbohydrates conversion to sugar, limiting spikes in blood sugar that promote insulin resistance and diabetes. The acids in lemon juice also help to prevent and dissolve kidney stones.
Lemon juice contains a significant amount of vitamin C, which is a powerful antioxidant, says Medical News Today. Vitamin C strengthens the immune system to defend against infection and cellular damage. Vitamin C from lemon juice, taken orally or applied directly to the skin, protects against sun damage, wrinkles and pollution.
The vitamin C in lemon juice also neutralizes toxic free radicals and oxidation that cause cancer, according to Cleveland Clinic. Additionally, individuals who consume a high amount of vitamin C have a lower risk of developing asthma.
Lemon juice is a heart-healthy food that may lower the risk of ischemic stroke in women, states Medical News Today. It also increases the body's ability to absorb iron.
