    Original title: How to correctly understand the nutritional value of apples? Experts come to
    the proverbial cloud "one apple a day, doctor away from me", often eat apples for good health. Data show that apple belongs to the rose section, China is the world's largest apple production and consumption, apple production accounted for about 50% of the world. China's apple production areas are mainly concentrated in Shaanxi, Shandong, Henan, Shanxi, Hebei, Liaoning, Gansu and other 7 provinces, apple production accounted for about 90% of the country. Apple is rich in nutrition, containing sugar, acid, vitamins, flavonoids, dietary fiber, phosphorus, mineral elements and many other nutrients, the value is quite high., sugar and acids
    about 80% of the total energy consumed by humans is provided by sugar. Apples provide more than 180 kJ of energy per 100 grams of sugar in the portion. Apple soluble sugar content is generally between 8% and 13%, mainly glucose, fructose and sucrose, fructose accounted for more than 40% of the sugar content. Glucose and fructose are monosaccharose, sucrose is two sugars, monosaccharose can be directly absorbed by the body. Sugar, as a sweet substance of apples, can delight the body and mind.
    acids in apples are mainly cider acid, and the content of other organic acids such as citric acid is not high. Organic acids are the sour substances in apples. Acids in apples have the effect of eliminating fatigue, enhancing appetite, promoting digestion, softening blood vessels, lowering blood cholesterol, and so on, and apple acid and citric acid can also improve the body's absorption of calcium., vitamins and flavonoids
    mainly vitamin C in apples, with a content of about 3 mg/100 g. Vitamin C can enhance immunity, prevent and treat iron deficiency anemia, malignant anemia and scabies, promote collagen formation and steroid metabolism, maintain the normal function of bones and teeth and cell membrane integrity, lead chemicals, arsenides, benzene, bacterial toxins and other detoxifying effects, but also anti-aging. In addition to vitamin C, apples also contain vitamins such as thiamine, nucleolulatin, niacin, folic acid, and sterols. These vitamins are also very beneficial to human health.
    flavonoids, as a class of major polyphenols in apples, have antibacterial, antiviral, anti-inflammatory, anti-allergic, dilated blood vessels and inhibit lipid peroxidation, platelet polymerization, capillary permeability, epoxyase and lipid oxidase activity. There are four main types of flavonoids in apples, namely flavanols, flavonols, dehydrocharone and anthroposide, flavonoids are found only in the peel, anthroposide is only found in the red apple peel. Apples are rich in flavonoids, which are much smaller in the flesh than in the peel. Therefore, it is best not to peel apples. And eating apples with skins has a better flavor and taste.3. Dietary fiber and phosphorus
    dietary fiber is the seventh largest nutrient in human beings, can prevent overnutrition obesity, diabetes and hypertension, but also prevent coronary heart disease, arteriosclerosis, constipation and gallstones. Dietary fiber in apples includes soluble dietary fiber and insoluble dietary fiber. It was determined that the average content of dietary fiber in apples was about 1.8%, of which the average content of insoluble dietary fiber was about 1.4% and the average content of soluble dietary fiber was about 0.4%. The cellulose content of apple peel is much higher than that of fruit, which is 2 to 3 times higher than that of the latter.
    is a kind of dietary fiber, with the prevention of obesity, blood lipid reduction and other effects. The gel is divided into raw gel and soluble gel. The raw gel in the immature fruit is in the cell wall, linked to cellulose, and when the fruit matures, the raw gel is transformed into soluble gel. According to our study of 182 varieties, the average gel content in apples is 0.8%., minerals
    apples contain nitrogen, potassium, phosphorus, calcium, magnesium and other large elements and boron, zinc, manganese, iron, aluminum and other trace elements. Potassium is highest in a large number of elements. The trace element has the highest iron content. Minerals are an important component of human tissue, are the body's components with special physiological functions and a variety of enzymes of the active agent, can maintain the body's normal acid-base balance and osmotic pressure, as well as nerve, muscle excitability and cell membrane permeability.
