7. Heart health
The flavonoids, vitamin C, and pectin in lemon peel assists in managing cardiovascular disorders by preventing heart diseases, diabetes, and improving blood circulation. The pectin and d-limonene also decrease cholesterol levels and promote good heart health. Controlling cholesterol levels lowers the risk of diabetes, obesity, and cardiovascular diseases. Lemon peels also have abundant amounts of potassium that help in the regulation of blood pressure.
A short-term study done with overweight children showed lower LDL and blood pressure levels when they were given pulverized lemon peel. A systematic review of multiple studies also showed that increased flavonoid uptake in humans lowers the risk of heart disease.
