A single medium-sized lemon provides about 30 mg of vitamin C. This is about 50 percent of the daily recommended intake by the USDA. Research has shown that adding foods that contain high levels of vitamin C to your diet can reduce the risk of heart disease or stroke.

Lemons also contain fiber and the plant compounds diosmin and hesperidin. These have been found to reduce the risk factors for developing heart disease by controlling high levels of LDL cholesterol.

Kidney stones, tiny deposits of crystallized waste that develop in the kidneys, are more likely to occur in those who have suffered them previously. Studies show that drinking ½ cup of lemon juice a day can provide enough citric acid to prevent kidney stones in people that have previously experienced them. Because lemons are high in citric acid, they aid in increasing the production of urine. They also increase the pH levels in urine. These factors create an environment in the kidneys that is more likely to prevent kidney stones from forming.

Lemons are also rich in antioxidants, this factor along with the high content of vitamin C make lemons very effective at countering inflammation and protecting the cells of the immune system.

According to researchers in the November 4, 2019 issue of Medical News Today, eating a whole lemon every day can help improve the immune system and protect you from several illnesses.
