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 in addition to traditional nutrients such as pectin fiber and vitamins, apples also contain a large number of antioxidants, which may be as many as hundreds. In the experiment, apple has strong antioxidant capacity. Previous studies have found that green tea, grapes and citrus peels 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. In the study, it was found that both 100% fruit juice and all-natural apple have this antioxidant capacity, which can be used for anti-aging, beauty and early maintenance of young people, and the elderly can protect the cardiovascular system from stroke and heart disease, or 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, so eating the whole apple will not have this trouble, and it will also improve digestion and defecation. (Jin Wei) Smelling apples relieves headaches-A study by the Smell and Taste Foundation of Chicago, USA, proves that smelling green apples can effectively relieve migraines. Fifty subjects were asked about the degree of pain during three migraine attacks and after 10 minutes. They smelled the tasteless bottle for the first time and the third time, and the green apple for the second time. As a result, migraine disappeared or eased obviously after smelling the fragrance of green apples, but neither disappeared nor eased after smelling the tasteless bottle.
