Apple peel extract can delay the aging process. Eat apples, don’t peel them

"An apple a day keeps the doctor away from you" is a well-known health proverb However, the best way to eat apples is to take the skin with you According to the latest issue of Nature Medicine, US researchers found that the combination of dasatinib (a leukemic drug) and quercetin (an extract from apple peel) can prolong the life span of old mice by 36% Senescent cells usually appear in the human body in their 60s, but earlier in obese or chronic patients These abnormal cells are in a state of decline, but they are not willing to die It is believed that aging cells themselves can catalyze the process of aging A team led by James Cochran of the Mayo Clinic in the United States has shown that this is indeed the case When the researchers injected a small amount of senescent cells into six-month-old mice, their speed, endurance and strength decreased by 20% to 50% in a few weeks, almost the level of a typical two-year-old mouse To block the effects of aging cells, the team chose a combination of dasatinib and quercetin, both of which interfere with the way aging cells avoid death When the team gave the combination to mice that had aged from the injection of senescent cells, the mice recovered 50% to 100% of their lost physical ability within two weeks When the team gave the drug to older mice aged 24 to 27 months, the speed, endurance and strength of these mice increased by 30 to 100%, and their remaining life span was 36% longer than that of those without the drug Nutritional value of apple peel Apple ranks first among the 30 anti-cancer fruits and vegetables promoted by the American Cancer Society, because it is rich in vitamin C, vitamin E and β - carotene, which can effectively prevent heart disease and cancer In addition, apple peel is rich in guest oxidation substances In addition, there is a special "pectin" component in apple, which is a kind of water-soluble fiber The main function of the skin between the pulp and the peel is to help the body excrete cholesterol to the outside body, so as to achieve the purpose of lowering cholesterol The content of total polyphenols in apple peel is 307mg / 100g, total flavonoids is 184mg / 100g, procyanidins is 105mg / 100g These data are beyond the reach of flesh It was found that polyphenols extracted from Apple have significant anti radiation effect, which can delay the survival period of animals exposed to radiation; it can also promote the excretion of lead pollution in animals, and significantly reduce the lead content in liver, bone and blood of lead poisoned mice It can be seen that although apple peel contains a little more lead than pulp, it also has a strong ability to help eliminate lead poisoning Compared with each other, the benefits and harms are not so terrible What are the benefits of eating apple peel? It is rich in dietary fiber Dietary fiber plays an important role in promoting good digestion and excretion of solid waste Eating an apple when constipated has a good effect The skin of an apple contains more than twice as much dietary fiber as the flesh The skin of a medium-sized apple contains 4.4g of dietary fiber, while the flesh contains only 2.1g If apples are peeled before eating, the intake of dietary fiber will be greatly reduced An apple rich in vitamins contains about one third more vitamin C and vitamin A in its skin than in its meat And vitamins, especially vitamin C, are common to important people Don't you eat skin Protecting the lung apple peel contains the natural antioxidant quercetin, which can protect the lung from pollutants Especially in the haze days, apple peel is a health food to improve lung function Can protect memory in addition to the antioxidant quercetin helps prevent degenerative diseases of brain tissue damage, thereby protecting memory There are more than ten triterpenoids in apple peel that can inhibit the growth of cancer cells such as liver cancer, colon cancer or breast cancer and also kill cancer cells The dietary fiber and vitamin content in the apple skin are very high, and the apple skin can increase the sense of fullness, which can effectively promote digestion and resist hunger for people who lose weight It is suggested to eat apples instead of dinner every day to relieve obesity Eat the apple peel notice 1, might as well choose the apple which the bagging handles preferentially This kind of apple skin is clean and even, which is less affected by pollution gas and pesticide spraying 2 Apples mature in autumn Fresh apples are sold without preservative treatment at that time, so it is safer to eat the peel The most uneasy thing is the foreign apples that come from overseas, because they must be preserved, and waxing of foreign fruits is more common 3 There is a natural layer of fruit wax on the surface of fresh apple, but there is also a thin fruit powder, which is not a light discernable appearance After apple harvest, in order to improve the commodity value and delay the water loss of apple, waxing machine is often used for polishing, and there may be problems such as preservative treatment, so it is better to peel and eat the apple with beautiful and shiny surface, especially the off-season apple 4 It is better to choose the apple with pollution-free, green and organic certification Such Apple will have much less heavy metal and pesticide residues, even if it is not equal to zero, it will also have less residues than the ordinary apple skin, and it is more reassuring to eat the apple skin Which kind of Apple should be peeled Apple ranks first among the 30 anti-cancer fruits and vegetables promoted by the American Cancer Society, because it is rich in vitamin C, vitamin E and β - carotene, which can effectively prevent heart disease and cancer In addition, apple peel is rich in guest oxidation substances In addition, there is a special "pectin" component in apple, which is a kind of water-soluble fiber The main function of the peel between the flesh and the peel is to help the body drain cholesterol out of the body, so as to reduce cholesterol However, some apples are best peeled and eaten During the process of planting vegetables and fruits, apple farmers who use pesticides will add pesticides Therefore, it is suggested that consumers should wash them with flowing water for more than 15 minutes before eating Because the pesticides are water-soluble, most of them can be washed out by flowing water However, it is not clear what kind of pesticides the operators add, so it is recommended to peel and eat them The apple in the fruit wax Operators usually add a layer of fruit wax, mainly to increase the glossiness of the appearance and attract consumers to buy, but these fruit wax are not natural substances, but chemical substances, such as insect wax, oxidized polyethylene, etc Although these are legal in Taiwan, the metabolite of oxidized polyethylene, 1,4-oxo-n-land circle, will be converted into nitrous acid through the body, so that There is a risk of cancer.
