Apple skin is rich in antioxidant components and bioactive substances, so eating apple skin is good for health. Apple peel contains many bioactive substances, such as phenols, flavonoids and octacosanol. These bioactive substances can inhibit angiotensin converting enzyme, which leads to hypertension, and help to prevent chronic diseases such as cardiovascular disease and coronary heart disease, and reduce their incidence.
Therefore, it is best to eat apples with skin after cleaning.
