The role of apples:

1, lose weight: apples will increase satiety, and eating before meals can reduce food intake and achieve the purpose of losing weight.

2. Prevention of cancer: Polyphenols in apples can inhibit the proliferation of cancer cells. A study in Finland found that flavonoids contained in apples are an efficient antioxidant, not only the best vascular cleaner, but also the bane of cancer.

If people eat more apples, the risk of lung cancer can be reduced by 46%, and the risk of 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.

3. 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.

4. Antioxidant effect: The research team of Cornell University in the United States soaked 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, quercetin in apples is the best, and red apples are better than yellow apples and green apples. Therefore, apples are the best food for patients with Alzheimer's disease and Parkinson's disease.

5. Lowering blood lipid: The human experiment of Japan Fruit Research Institute showed that after eating two apples a day, the blood triglyceride level of the subjects decreased by 265,438+0% 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 content.

6. Lowering blood pressure: Excessive sodium is an important factor causing hypertension and stroke. Apples contain enough potassium, which can be combined with excess sodium in the body and 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 Arlich, a famous British pharmacologist, found that polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases.

Extended data:

Never chew seeds when eating apples.

Like cherries and almonds, apple seeds also contain cyanide, but the content is not high. Apple seeds will be eaten by people if they are not careful, but you will feel uncomfortable if you eat too much.

There are no toxic chemicals in the pulp, but you will find cyanide in the apple core. Eating an apple core won't kill you, but it's definitely bad for your health. Of course, if you eat too many apple cores, there may be complications.

People's Network-Eating more apples can prevent cancer and lose weight, but don't chew seeds when eating apples.
