Health care: what are the benefits of eating apples? Be careful not to bite the nucleus or cause dizziness, headache, dyspnea

Apple is rich in a variety of healthy nutrients, health care effects are numerous, loved by people all over the world But a recent article on perfit, an Australian website, warned that eating apple should not be too hard, because its core contains hydrocyanic acid, which is harmful to health As we all know, apple is rich in vitamin C, vitamin E, polyphenols and flavonoids, which are natural antioxidants, especially effective in preventing cardiovascular and cerebrovascular diseases The calcium content of apple is much richer than that of common fruit, which can help to metabolize excess salt and help to lose weight However, it is rarely known that the apple core contains hydrocyanic acid Australian researchers found that apples contain a small amount of harmful substances - hydrocyanic acid A large amount of hydrocyanic acid is deposited in the body, which will cause dizziness, headache, rapid breathing and other symptoms, and may cause coma in severe cases But don't worry too much, hydrocyanic acid in apple is mainly in the core, not in the flesh It should be reminded that eating apples habitually to the core will not lead to poisoning immediately, but it is really harmful to health for a long time Eating apples can't get to the core, so can the wax on the apple skin be eaten? When many people don't peel and eat apples, they often feel that there will be oil and wax on the surface of apples, so they worry about whether the wax layer will do harm to the body? Fan Zhihong said that there are mainly three kinds of wax on the peel: the apple surface itself has a layer of fruit wax, which is a lipid component, a plant protective layer generated on the surface of the apple, which can effectively prevent the invasion of external microorganisms, pesticides, etc into the pulp, and play a protective role; some high-grade apples with wax, which is an artificial edible wax, this "artificial fruit Wax "is actually a kind of chitosan material, which is mostly extracted from crabs, shells and other crustaceans This material itself is harmless to the body Its function is mainly to keep fresh and prevent apples from rotting during long-distance transportation and long-term storage To remove this layer of wax, it is also very easy to use You can remove this layer of artificial edible wax on the surface of Apple by washing it directly with hot water What people should worry about is actually the third kind of wax - illegal hawkers use industrial wax to wax fruits The mercury and lead contained in the wax may penetrate into the pulp through the peel, causing harm Therefore, when selecting waxed fruit, you can use your hand or napkin to wipe the surface of the fruit If you can wipe a layer of light red, don't buy it This is probably industrial wax In addition, we also need to know that there are many kinds of apple whose peel is more nutritious than the pulp There are not only crisp and sweet Gala, Fuji and Guoguang apples, but also soft banana apples There are not only domestic local apples, but also imported snails that float to Beijing by sea So many kinds of apples, which one is the most nutritious? Fan Zhihong, Ph.D., Department of nutrition and food safety, School of food science, China Agricultural University, told reporters that there are many kinds of apples, but the nutrition is the same We should choose apples according to personal tastes and preferences Whether apples should be peeled or even peeled has been debated for a long time Fan Zhihong said that from the point of view of nutrition alone, we must choose to eat with skin, because compared with pulp, apple skin is indeed rich in nutrition, has stronger antioxidant, and can prevent chronic diseases such as hypertension As the saying goes: an apple a day keeps the doctor away from me So, what's the advantage of eating apples?
