Apple is rich in sugars, organic acids, cellulose, vitamins, minerals, polyphenols and flavonoids, which is called "all-round healthy fruit" by scientists.

The health care function of apple;

1. Reduce blood lipid

The human experiment of Japan Fruit Research Institute showed that after eating two apples a day, the triglyceride level in the blood of the subjects decreased by 2 1% after three weeks, and the high triglyceride level was the chief culprit of arteriosclerosis. After apple pectin enters the human body, it can combine with bile acids, absorb excess cholesterol and triglycerides like a sponge, and then excrete it. At the same time, the acetic acid decomposed by apple is beneficial to the catabolism of these two substances. In addition, vitamins, fructose and magnesium in apples can also reduce their contents.

Step 2 lower blood pressure

Excessive sodium is an important factor causing hypertension and stroke. Apples contain enough potassium, which can combine with excess sodium in the body and be excreted, thus lowering blood pressure. At the same time, potassium ion can effectively protect blood vessels and reduce the incidence of hypertension and stroke. Dr Susan Allridge, a famous British pharmacologist, found that polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases.

Step 3 prevent cancer

Research by Hirosaki University in Japan confirmed that polyphenols in apples can inhibit the proliferation of cancer cells. A study in Finland is even more exciting: flavonoids contained in apples are an efficient antioxidant, which is not only the best blood vessel cleaner, but also the bane of cancer. If people eat more apples, the chances of getting lung cancer can be reduced by 46%, and the chances of getting other cancers can also be reduced by 20%. The latest research by the French National Institute of Health Medicine also tells us that proanthocyanidins in apples can prevent colon cancer.

Step 4 strengthen bones

Apples contain mineral elements boron and manganese that can 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 take 3 grams of boron every day, their calcium loss rate can be reduced by 46%, and menopausal women eat more apples, which is beneficial to the absorption and utilization of calcium and the prevention and treatment of osteoporosis.

Step 5 lose weight

Apples can increase satiety, and eating before meals can reduce food intake and achieve the goal of losing weight. In addition, the special substances contained in apples can make the toxins in the body be discharged smoothly, so that people can lose weight quickly and improve their physique.

6. Beauty

Apples can promote the production of white blood cells in the blood, improve the body's resistance and immunity, and at the same time promote nerve and endocrine functions, which will help beauty beauty.

7. 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) and enhance physical strength and disease resistance.

8. Antioxidant effect

The research team of Cornell University in the United States immersed the brain cells of mice in a liquid containing quercetin and vitamin C, and found that the antioxidant capacity of brain cells was significantly enhanced. Compared with other fruits and vegetables, the quercetin contained in apples is the best, and red apples are better than yellow apples and green apples. Therefore, for patients with Alzheimer's disease and Parkinson's syndrome, apples are the best food.
