Is it true that apple peel is more nutritious? Some people like to remove the apple skin when eating apples. However, research shows that apple skin is rich in antioxidant components and bioactive substances. Eating apple skin is beneficial to health. What nutrition does apple peel have?
Apple skin contains many bioactive substances, such as phenols, flavonoids, and twenty-eight alkanols, which can inhibit angiotensinconverting enzyme that causes high blood pressure, and help prevent chronic diseases such as cardiovascular disease and coronary heart disease, and reduce the incidence rate.
Moreover, apple skin intake can reduce the incidence rate of lung cancer. Foreign studies have shown that apple peel has stronger antioxidant activity than pulp, and the antioxidant effect of apple peel is higher than that of other fruits and vegetables. The antioxidant capacity of the peel of an ordinary size apple is equivalent to the antioxidant capacity of 800 mg of vitamin C.
Octacosanol in apple peel also has the effects of anti fatigue and strengthening physical strength. Apple peel can inhibit the enzyme activity of dental scale and the growth of bacteria in the mouth. It has anti-corrosion effect and can protect teeth. It can also make the skin white and tender, prevent the formation of melanin and have cosmetic effect.
At present, many manufacturers have developed functional foods by extracting bioactive substances from apple peel. As a valuable food additive, apple peel powder can be used to produce fortified food. A small amount of apple peel powder can increase the content of polyphenols and flavonoids in food.
Therefore, nutritionists' advice on apple peel is basically this: if you like to eat, continue to eat. If you don't like it, peel it thinly and don't blame yourself.
Advice on eating peel: 1. You might as well give priority to bagged apples. The apple skin is clean and uniform, and is less affected by polluted gas and pesticide spraying.
2. Apples mature in autumn. Fresh apples were sold at that time without preservative treatment. It was safer to eat peel. The most worrying thing is that foreign apples come from across the ocean, because they must be kept fresh, and waxing of foreign fruits is more common.
3. There is a layer of fruit wax on the surface of fresh apples, but there is also a thin layer of fruit powder, which is not visible. After apple harvest, in order to improve the commodity value and delay the water loss of apples, waxing machines are often used for polishing, and there may be problems such as preservative treatment. Therefore, it is best to peel and eat apples with particularly beautiful and shiny surface, especially out of season apples.
4. It is best to choose apples with pollution-free, green and organic certification. Such apples will have much less heavy metal and pesticide residues. Even if they are not equal to zero, they will have less residues than ordinary apple skins. Therefore, you can safely use apple skins.
