You can eat on an empty stomach, but not too much. Apple not only has high nutritional value, but also has health care function. Tannic acid, organic acid and other substances in apple have astringent effect; Pectin and cellulose can absorb bacterial toxins, so they can help the intestines stop diarrhea; Organic acids and cellulose can promote intestinal peristalsis, thus playing a laxative role. Therefore, to treat chronic diarrhea and dry stool, you only need to eat 1 apple on an empty stomach every morning and evening, which can be effective; For the treatment of watery diarrhea, half-cooked apples should be boiled in water and eaten with soup. But be careful not to eat too much, because apples contain a lot of malic acid, vitamin C and citric acid. Eating too many apples on an empty stomach will react with gastric acid, forming a lump that is not easy to melt, leading to acute inflammation of the stomach. Apple has recently been regarded as a beauty sacred product by many beauty lovers. Many apple diet meals, apple beauty meals and even apple fasting methods have been released one after another. We can't judge whether these effects are harmful to health, but eating apples often is a good way to prevent cancer and protect blood vessels. Researchers at the University of California, Davis, found that apples contain a lot of antioxidants in addition to traditional nutrients such as pectin fiber and vitamins. There may be hundreds of these antioxidants. In the experiment, apple has strong antioxidant capacity. Previous studies have found that green tea, grape seeds and citrus peel all contain high antioxidants. These fruits with high antioxidant capacity are considered as sacred products against cancer and aging, because they can prevent free radicals from damaging cells and oxidizing low-density lipoprotein cholesterol. Today, apples are also in the forest of antioxidants. In the study, it was found that both 100% fruit juice and all-natural apples have this antioxidant capacity, which can be used for anti-aging beauty and early maintenance for young people, and can protect the cardiovascular system from stroke and heart disease for the elderly, or can fight against early cancer. However, it is worth noting that apple juice on the market usually adds sugar to enhance its flavor, so we can't help but pay attention to the problem that apple juice may be high in calories. A bottle of 500c.c pure juice has 240 calories, and you may have to jog for more than 30 minutes to digest these calories. Eating the whole apple will not have this problem, and it will also improve digestion and defecation. By the way, you ate 10 apples. The cause of gastrointestinal discomfort is overeating.
