As the saying goes, "An apple a day keeps the doctor away," apples have become a popular fruit for many people since this saying emerged.Indeed, statistics show that apples are the best-selling fruit. However, this nutritious fruit is not immune to pesticide contamination. How can we clean apples properly? Should we eat apples with or without the peel? Many people believe that apples have a lot of pesticide residue, so it's best to eat them without the peel.
However, the peel of apples contains a lot of bioactive substances, such as phenolic compounds, flavonoids, and octacosanol, which can inhibit the conversion of angiotensin, which is a key factor in blood pressure, and help prevent chronic diseases such as cardiovascular disease and coronary heart disease.
Foreign studies also show that the peel of apples has stronger antioxidant properties than the flesh, and the antioxidant effect of the apple peel is higher than that of other fruits and vegetables. The antioxidant capacity of the peel of a normal-sized apple is equivalent to 800 mg of vitamin C.The octacosanol in the apple peel also has the effects of reducing fatigue and enhancing physical strength. What nutrients are found in the apple peel?
Vitamins: Researchers at the University of Illinois have found that the apple peel contains a lot of vitamin A and vitamin C. Vitamin A, also known as retinol, helps maintain normal vision and bone growth. Vitamin C promotes wound healing and enhances the body's immune system.
Minerals: Researchers at the University of Illinois believe that the apple peel contains a lot of minerals, including calcium, potassium, phosphorus, iron, and folic acid. Eating apple peel is also beneficial for the body's absorption of minerals.
Calcium and phosphorus make teeth and bones stronger, potassium strengthens the heart and digestive function, and iron is essential for the normal production of red blood cells, preventing anemia, and maintaining overall health.
