Discarding lemon peel when using lemons is a common habit for most people. However, according to several studies, it is a treasure trove packed with abundant vitamins and nutrients. So, what surprising health benefits can keeping lemon peel bring to you?
Rich in Powerful Antioxidants
Lemon peel is rich in essential antioxidants such as vitamin C, D-limonene, and the flavonoid hesperidin. These compounds help strengthen the immune system and reduce the risk of certain health conditions.
Research shows that the peels of citrus fruits provide even more antioxidants than their juice or pulp. In particular, preliminary evidence on lemon peel indicates that its antioxidant activity is even stronger than that of mandarin peel or grapefruit peel.
Provides Essential Nutrients
Lemon peel is low in calories (only about 3 calories per tablespoon) while containing 1 gram of pectin fiber—a crucial type of dietary fiber. The peel of this fruit also provides 8 mg of calcium, small amounts of potassium and magnesium, and meets about 9% of the daily value for vitamin C.
Supports Oral Health
Several studies indicate that lemon peel may support oral health by inhibiting the growth of bacteria in the oral cavity—the primary culprits behind tooth decay and gum infections.
In another study, lemon peel extract was shown to be effective against Streptococcus mutans, the bacteria responsible for dental caries. This further reinforces the evidence that other components of this fruit can also deliver similar benefits for oral health.
Reduces the Risk of Cardiovascular Disease
Several nutrients and antioxidants in lemon peel can help lower high blood pressure, high cholesterol, and obesity—factors linked to cardiovascular disease. Overweight and obese adolescents who took lemon peel supplements experienced reductions in blood pressure and LDL cholesterol levels.
Possesses Antifungal and Antibacterial Properties
Laboratory studies show that lemon peel can help inhibit the growth of harmful bacteria and fungi. The natural antimicrobial and antifungal compounds in lemon peel have the ability to fight against and reduce the proliferation of microorganisms on the skin and within the body.
When combined with vinegar, lemon peel can also be used to make an excellent all-purpose natural cleaner.
