Finnish researchers have published a research report that eating apples often can reduce the risk of lung cancer. They pointed out that flavonoids contained in apples-important antioxidants produced by plants through metabolism-are the main reasons for reducing the incidence of lung cancer. During the 30-year research, the Finnish National Institute of Public Health investigated the dietary patterns of about 1888 Finns. The results showed that the main reason for preventing cancer was not vitamin C and β-carotene contained in fruits and vegetables, but flavonoids contained in apples, vegetables and other fruits. Investigators obtained a flavonoid compound called quercetin from apples. Those who normally eat apples, onions, fruit juice, vegetables and jam containing the most flavonoids as required have a 20% reduction in the prevalence of lung cancer. Those who often eat foods containing flavonoids, especially apples, reduce the prevalence of lung cancer by 46%. To this end, Mr. Granger Bayint, manager of the sales and service department of Tritop Company, the world's largest apple juice production company, pointed out: "This is an exciting information for the world, and we look forward to further understanding of the effectiveness of apple."

Researchers at Cornell University in the United States found that a chemical mixture in apples is very important for human health, and this mixture plays an important role in fighting cancer and antioxidation. This antioxidant exists in the skin and pulp of apple. Researchers administered 50 mg of concentrated extract of apple to colon cancer cells. The results showed that the concentrate extracted from apple skin can reduce the growth of cancer cells by 43%, and the concentrate extracted from apple meat can reduce the growth of cancer cells by 29%. In addition, researchers also used the extract of fruit to treat liver cancer. The results showed that the concentrate extracted from apple skin can reduce the growth of cancer cells by 57%, while the concentrate extracted from apple meat can reduce the growth of cancer cells by 29%. This study shows that no single substance can reduce cancer. On the contrary, the mixture of various chemicals in apples is very effective. Eating water and vegetables is better than taking extra vitamin supplements. People can get enough antioxidants from food without worrying about any possible harm.
