In fact, the scientific community has already had an answer to this question. Fan Zhihong, an associate professor of food and nutrition at China Agricultural University, said, "An apple a day keeps the doctor away." This statement is right!
Can an apple a day really keep the doctor away? Judging from the nutritional value of apples in life, compared with other common fruits, such as oranges, pears, bananas, etc., apples have no outstanding nutritional components, but are in a relatively balanced position. Apple, as a fruit that is often eaten in life, can provide us with more vitamins and minerals, and also contains more dietary fiber. Some plant components are more obvious, such as vitamin C, carotene and vitamin B.
From it, we can see that apples are really helpful to our health, but there are some exaggerated elements in the sentence "an apple a day keeps the doctor away". Eating apples can't stop us from seeing a doctor, but it is good for our health.
Modern medical research shows that apples contain a lot of organic acids and cellulose such as malic acid and citric acid, and are rich in vitamin B 1, vitamin B2, vitamin C, carotene and mineral elements such as calcium, iron and zinc. Apples contain natural chemical antioxidants such as polyphenols and flavonoids, which can remove the metabolic "garbage" in the body in time and reduce the content of neutral fat in the blood. Neutral fat is the chief culprit of vascular sclerosis, which is particularly important for preventing cardiovascular and cerebrovascular diseases.
You can always hear the saying that you can't eat apples without choosing the time to eat them after or before meals. But in fact, whenever a healthy person eats an apple, the digestive system will work normally and absorb the nutrients in the apple. You don't need to pick a time, just eat one if you want.
Expert advice? It takes 15 minutes to eat an apple. In other words, eat apples slowly. Chewing slowly is not only beneficial to digestion, but also can use the organic acids and fruit acids in apples to kill oral bacteria and protect oral cavity.
The conclusion needs special attention. Never eat moldy apples. The results showed that the content of patulin in moldy apple could reach 10%~50% of that of moldy apple, even though it looked normal. Toxicological tests show that patulin has toxic effects on fertility, carcinogenesis and immunity, and it is also a neurotoxin.
