1. Metabolize cholesterol After the apple enters our intestines, it will break down a substance called acetic acid. You should not underestimate the effect of cholesterol on cholesterol metabolism. This is because after the acetic acid is decomposed in the intestine, after a series of reactions, excess cholesterol is excreted from the body. In addition, vitamin C, fructose, and magnesium contained in apples also promote the metabolism of cholesterol, thereby protecting blood vessel health. 2. Protect the liver Since apple itself does not contain cholesterol, you will not cause excessive levels of cholesterol even if you eat too much, and at the same time, you can promote cholesterol from your bile by your own reaction. The apple contains a large amount of pectin, which can prevent reabsorption of cholic acid in the intestine and excrete it out of the body, thereby weakening the enterohepatic circulation and increasing the excretion of cholesterol. 3. Prevention and treatment of coronary heart disease The study found that people who eat more than three apples a day can maintain their blood pressure at a low level for a long period of time, and blood pressure fluctuations will not be significant. From this point we can see that Apple has the role of protecting blood vessels, but also contains fructose and various trace elements in apples, which are conducive to the metabolism of cholesterol. Therefore, if you want to prevent or treat cardiovascular and cerebrovascular diseases, you can usually eat more apples, especially people with coronary heart disease. Apple is an excellent medicine. From the above aspects, we can see that the benefits of moderate consumption of apples are huge, but at the same time, it should be noted that people who suffer from gastrointestinal diseases should eat as little as possible.
