As the saying goes, “An apple a day keeps the disease away from me.” Apple is undoubtedly recognized as a healthy fruit. However, many people peel apples when eating them, which is too bad. In fact, apple peel is more nutritious than apple pulp.
Japan’s Aomori Prefecture, which is famous for producing apples, pointed out in its “Aomori Apple Strategy Association website” that the apple peel and the part between the peel and pulp are more nutritious than the apple pulp.
There are a lot of “apple polyphenols” here, of which epicatechin, procyanidins and anthocyanins are representative. These polyphenols have many effects such as reducing blood lipid, anti-aging, anti-cancer and so on, which are very beneficial to human body.
Japanese Anti-aging Medical Association found that apple polyphenols can effectively inhibit wrinkles caused by excessive ultraviolet rays. Even eating apples with skins can help produce Prevent wrinkles.
In addition to polyphenols, apple peel is rich in dietary fiber, iron, potassium and vitamins A, C, E, K, etc. Among them, the dietary fiber in apple peel is half of the total fiber content of apple.
Japanese nutritionist Ameba (website) also pointed out that the contents of potassium and vitamin E in apple peel and its adjacent peel are 2 times and 4 times that in pulp, respectively.
Five Common Nutrients in Apple Peel
Apple Skin Nutrition 1: Proanthocyanidins
Proanthocyanidins in apple peel have strong antioxidant capacity, and have the effects of reducing blood lipid, resisting cancer, eliminating halitosis, preventing tooth decay, whitening skin, etc.
Apple Skin Nutrition 2: Epicatechin
Epicatechin is also a high antioxidant active ingredient, which can reduce cholesterol concentration in blood, prevent dental caries and periodontal disease, and inhibit harmful bacteria in intestinal tract and helicobacter pylori in gastric inside.
Apple Skin Nutrition 3: Anthocyanin
Anthocyanin in apples is mainly found in the peel. Anthocyanin can improve vision, prevent eye fatigue, and also has effect in preventing eye diseases such as cataract and glaucoma. In addition, anthocyanin can also promote metabolism and smooth blood circulation.
Apple Peel Nutrition 4: Pectin
The rich water soluble dietary fiber between apple peel and pulp is called “apple pectin”. This apple pectin has more than twice the detoxification capacity of other pectins and can inhibit harmful bacteria. In addition, it also has the functions of lowering cholesterol level, inhibiting blood sugar level rise, preventing constipation, and promoting visceral fat decomposition, which is also helpful for cancer prevention.
Apple Peel Nutrition 5: Potassium
Potassium is responsible for the excretion of excess salt in the human body, has diuretic and detumescence effects, and helps prevent hypertension and arteriosclerosis.
Method for eating apple with peel
The simplest way to eat apples together is to bite directly, which can improve the chewing power of teeth and eat complete fiber.
However, many people do not like eating apples with skins because the skins taste hard and the taste is not so good.
You might as well cut the apple peel into smaller sizes and boil it in a pan to make apple sauce. Or roast the whole apple.
These methods can make the peel taste smoother.
Attention to 2 Points in Cleaning Apple Peel
For apple skins, people are most concerned about the problems of “pesticides” and “fruit wax”. In order to avoid skin contamination, attention should be paid when cleaning apple skin:
Flowing clear water+brushing to remove apple pesticide
When planting apples, farmers usually use pesticides to prevent diseases and insect pests.
There is not much pesticide residue in apples. Rubbing apples with a large amount of flowing clean water can remove most of the pesticides, and brushing with a soft brush is better.
At the same time, the two sunken parts of apple are easy to accumulate pesticides, so it is recommended to cut them off and not eat them.
Fruit wax on Apple Peel
Scraping the apple surface may scrape out white powder, which is usually the natural fruit waxing produced by the apple itself during its growth. It is used to prevent the evaporation of water in the pulp, prevent diseases and keep it fresh. This natural fruit waxing is harmless to human body.
Some apples will be waxed manually, especially imported apples, which need long-distance transportation. Without waxing, apples will easily lose moisture and deteriorate.
Artificial wax is divided into edible wax and industrial wax. Edible wax is safe for human body and can also be removed by gently brushing with a soft brush under warm water flow. However, some unscrupulous manufacturers may use industrial wax, which contains lead, mercury and other substances and is not edible. Wipe the apple surface with paper towel. If reddish substances can be wiped off, it may be industrial wax.
In order to ensure eating peace of mind, it is best to buy apples from reliable merchants or organic apples.
Last but not least, people with bad intestines and stomach should eat it after peeling, because apple peel has high fiber content and is relatively difficult to digest.
