Apples are rich in sugars, organic acids, fiber, vitamins, minerals, polyphenols and flavonoids nutrients, scientists called the "full range of health fruit". So, what exactly are the health effects that have earned it such a reputation?
Lowering blood lipids: Japan's Fruit Tree Research Institute of human experiments show that eating two apples a day, three weeks after the subjects in the blood triglyceride levels decreased by 21%, and high triglyceride levels are the main culprits of vascular sclerosis. The pectin in apples enters the body and binds with bile acids, absorbing excess cholesterol and triglycerides like a sponge, and then excretes them from the body. At the same time, the acetic acid decomposed by apples facilitates the decomposition and metabolism of these two substances. In addition, the vitamins, fructose and magnesium in apples can also reduce their levels.
Lowering blood pressure: Excess sodium is an important factor in causing high blood pressure and stroke. Apples contain sufficient potassium, which can combine with excess sodium in the body and expel it from the body, thus lowering blood pressure. At the same time, potassium ions can effectively protect blood vessels and reduce the incidence of hypertension and stroke. Dr. Susan Orridge, a renowned British pharmacologist, found that the polyphenols and flavonoids contained in apples can effectively prevent cardiovascular disease.
Prevention of cancer: A study by Hirosaki University in Japan confirmed that polyphenols in apples can inhibit the proliferation of cancer cells. And a Finnish study is even more exciting: apples contain flavonoids is a highly effective antioxidant, it is not only the best blood vessel cleaner, but also cancer nemesis. 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%. A recent study by the French National Institute of Health and Medical Research (INSERM) also tells us that proanthocyanidins in apples can prevent colon cancer.
Antioxidant effect: A research team from Cornell University dipped the brain cells of rats into a liquid containing oak extract 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 extract, and red apples are better than yellow and green apples. Therefore, for people with Alzheimer's disease and Parkinson's syndrome, apples are the best food.
Strengthening bones: apples contain the bone-strengthening minerals boron and manganese. A study in the United States found that boron can greatly increase the concentration of estrogen and other compounds in the blood, these substances can effectively prevent calcium loss. Medical experts believe that menopausal women can consume 3 grams of boron per day, then their calcium loss rate can be reduced by 46%, menopausal women eat more apples, is conducive to the absorption and utilization of calcium, prevention and treatment of osteoporosis.
Maintaining acid-base balance: 70% of the diseases occur in the acidic body, and apples are alkaline food, eating apples can quickly neutralize the body's excessive acidic substances (including exercise acid and fish, meat, eggs and other acidic food in the body of the acid metabolites), to enhance the physical strength and resistance to disease.
