For a healthy body, an apple a day is indispensable
Research by Hirosaki University in Japan confirmed that the polyphenols in apples can inhibit the proliferation of cancer cells. And a Finnish study is even more exciting: the flavonoids contained in apples are a kind of high-efficiency antioxidants, which are not only the best blood vessel cleansing agent, but also a cancer killer. If people eat more apples, the risk of lung cancer can be reduced by 46%, and the risk of other cancers can be reduced by 20%. The latest research of the French National Institute of Health Medicine also tells us that the proanthocyanidins in apples can prevent colon cancer.
Apple contains 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, and these substances can effectively prevent calcium loss. Medical experts believe that if menopausal women can consume 3 grams of boron a day, their calcium loss rate can be reduced by 46%. Menopausal women eat more apples, which is conducive to the absorption and utilization of calcium and prevents osteoporosis.
Maintain acid-base balance
70% of diseases occur in people with acidic constitutions, and apples are alkaline foods. Eating apples can quickly neutralize excessive acidic substances in the body (including acid produced by exercise and acidic foods such as fish, meat and eggs produced in the body. Acidic metabolites), enhance physical strength and disease resistance.
A research team from Cornell University in the United States immersed mouse brain cells 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, apples contain the best quercetin, and red apples are better than yellow and green apples. Therefore, for patients with Alzheimer's disease and Parkinson's syndrome, apples are the best food.
Reduce blood fat
A human test conducted by the Japan Fruit Research Institute showed that eating two apples a day reduced the blood triglyceride level of subjects by 21% after 3 weeks, and the high triglyceride level is the culprit of vascular sclerosis. After the pectin of apple enters the human body, it can combine with bile acid, absorb excess cholesterol and triglycerides like a sponge, and then excrete it from the body. At the same time, acetic acid decomposed by apples is beneficial to the catabolism of these two substances. In addition, the vitamins, fructose and magnesium in apples can also reduce their content.
Lower blood pressure
Excessive sodium is an important factor in causing high blood pressure and stroke. Apple contains sufficient potassium, which can combine with excess sodium in the body and excrete it from the body, thereby lowering blood pressure. At the same time, potassium ions can effectively protect blood vessels and reduce the incidence of hypertension and stroke. The famous British pharmacologist Dr. Susan Orrich discovered that the polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases.
Apples will increase the feeling of fullness, and eating before meals can reduce the amount of food consumed and achieve the goal of weight loss.

Nutritional analysis pointed out that apples contain the most fructose, and contain a variety of organic acids, pectin and trace elements.
Apple pectin is a soluble fiber, not only can promote cholesterol metabolism, effectively reduce cholesterol levels, but also promote fat excretion. The French conducted an experiment in which a group of healthy middle-aged men and women ate two or three apples a day. One month later, their cholesterol levels were measured and found that 80% of the people had low-density lipoprotein cholesterol (LDL). Also called bad cholesterol) has been reduced; at the same time, high-density lipoprotein cholesterol (HDL is good cholesterol) has increased. Apple's help for the cardiovascular system is evident.
Potassium, a trace element contained in apples, can dilate blood vessels, which is beneficial to patients with high blood pressure. Zinc is also necessary for the human body. When lacking, it can cause disorders of blood glucose metabolism and decreased sexual function.
In addition to the above benefits, eating raw apples can also regulate the intestines and stomach, because it is rich in fiber and helps excretion. On the other hand, it is also good for people with diarrhea to eat it.
As for whether to peel an apple, it is a matter of opinion. Without peeling, it is possible to eat pesticides. Peeling. The most nutritious part of an apple is the skin, and most of the fiber is in the skin.
