According to the determination of the Ministry of Agriculture, red Fuji apple fruit contains 17.2% soluble substances, titratable acid 0.25%, sugar-acid ratio of 47:56, VC4.41 mg per 100 grams of pulp, and also contains carotene, fat, protein, Ca, Fe and other nutrients needed by the human body.
Lowering blood lipids: Human trials by the Japan Fruit Research Institute showed that after eating two apples a day, the blood triglyceride level of the subjects was reduced by 21%, and high triglyceride levels were the culprit of hardening of the arteries. After the pectin of apples enters the body, it can combine with bile acids, absorb excess cholesterol and triglycerides like a sponge, and then excrete them. At the same time, acetic acid, which is decomposed by apples, is conducive to the catabolism of these two substances. In addition, vitamins, fructose, magnesium, etc. in apples can also reduce their content.
Lower blood pressure: Excess sodium is an important factor in high blood pressure and stroke. Apples contain plenty of potassium, which binds to excess sodium in the body and is excreted from the body, lowering blood pressure. At the same time, potassium ions can effectively protect blood vessels and reduce the incidence of hypertension and stroke. Dr. Susan Orrich, a famous British pharmacologist, found that the polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases.
Cancer prevention: Research from Hirosaki University in Japan confirmed that polyphenols in apples can inhibit the proliferation of cancer cells. A Finnish study is even more exciting: the flavonoids found in apples are highly effective antioxidants, not only the best blood vessel cleansers, but also the nemesis of cancer. If people ate more apples, they could have a 46% lower chance of developing lung cancer and a 20% lower chance of getting other cancers. The latest research from the French National Institute of Health Medicine also tells us that the proanthocyanidins in apples can prevent colon cancer.
Antioxidant effect: The research team at Cornell University in the United States immersed the brain cells of mice in the liquid containing oak essence and vitamin C, and found that the antioxidant capacity of the brain cells was significantly enhanced. Compared with other fruits and vegetables, apples contain the best oak essence, while red apples are better than yellow apples and green apples. So, for Alzheimer's and Parkinson's patients, apples are the best food.
Strengthen bones: Apples contain the minerals boron and manganese that strengthen bones. A study in the United States found that boron can greatly increase the concentration of estrogen and other compounds in the blood, which can effectively prevent calcium loss. Medical experts believe that if menopausal women can ingest 3 grams of boron per day, then their calcium loss rate can be reduced by 46%, menopausal women eat more apples, which is conducive to calcium absorption and utilization, and prevents osteoporosis.
Maintain acid-base balance: 70% of diseases occur in people with acidic constitution, and apples are alkaline foods, eating apples can quickly neutralize excessive acidic substances in the body (including acid produced by exercise and acidic metabolites produced by acidic foods such as fish, meat, and eggs), enhance physical strength and disease resistance.
"One apple a day, the doctor stays away from me." Among the many fruits, the apple is arguably the most common and peaceful, but its nutritional value cannot be underestimated. Traditional Chinese medicine believes that it can nourish the lungs and strengthen the spleen and appetizing. Nutritional analysis shows that apples contain the most fructose and contain a variety of organic acids, pectin and trace elements.
Apple pectin is a soluble fiber, which can not only promote cholesterol metabolism, effectively reduce cholesterol levels, but also promote fat excretion. The French did an experiment in which a group of healthy middle-aged men and women ate two or three apples a day, and after a month, measured their cholesterol levels and found that 80% of people's blood LDL cholesterol (LDL is also called bad cholesterol) was reduced; At the same time, high-density lipoprotein cholesterol (HDL, or good cholesterol) increased. Apple's cardiovascular help can be seen.
The trace element potassium contained in apples can expand blood vessels, which is beneficial to hypertensive patients, and zinc is also necessary for the human body, which can lead to blood sugar metabolism disorders and decreased sexual function when lacking.
Eating apples raw, in addition to the above benefits, can also regulate the stomach, because it is rich in fiber and helps excretion. On the other hand, people with diarrhea also have benefits from eating it, because malic acid has an astringent effect, but it should be noted that if it is a chronic diarrhea of the spleen and stomach deficiency type, the apple must be wrapped in tin foil and baked or simmered before eating.
