Often discarded after the juice is extracted, lemon peel contains fibre, vitamin C and plant compounds that research suggests may support heart health, immunity and oral hygiene.
According to Healthline, one tablespoon of lemon peel provides about nine per cent of the daily value for vitamin C and one gram of fibre. It also contains antioxidants, including flavonoids and D-limonene, the compound responsible for lemon’s distinctive aroma.
These antioxidants help protect cells from damage caused by free radicals and may contribute to reducing the risk of certain chronic diseases.
Laboratory studies suggest that antibacterial compounds in lemon peel may inhibit bacteria associated with dental cavities and gum infections. Its fibre, particularly pectin, alongside flavonoids and vitamin C, may also help lower cholesterol and other risk factors for heart disease. Some studies involving lemon-based supplements have reported improvements in blood pressure and cholesterol levels.
Research has also identified potential antimicrobial and antifungal properties, including activity against certain drug-resistant bacteria. However, these findings largely come from laboratory studies and do not establish lemon peel as a treatment for infections in humans.
Scientists have investigated D-limonene for possible anticancer effects and its potential to dissolve gallstones. While some test-tube and animal studies have produced promising results, further human research is needed. Lemon peel should not be considered a cure or substitute for medical treatment.
Beyond its potential health benefits, lemon peel can be grated into salads, baked goods, soups and drinks, or added to tea. It can also be used in homemade cleaning solutions and as a natural deodoriser.
Before consuming lemon peel, wash the fruit thoroughly to reduce dirt and possible pesticide residue.
