Eating Apples

You probably know a famous saying about the importance of eating apples. It is, "An apple a day keeps the doctor away.

Now, a new American study shows eating apples may help fight cancer, too. Research scientists at Cornell University in New York say a combination⁵ of chemicals found in apples is important for good health. The study shows that the combination of chemicals plays an important part in anti-cancer activity.

The scientists say the chemicals are in both the skin and the flesh of apples. Results of the study were reported in the publication⁶ Nature. The Cornell researchers studied the chemicals, or extracts⁸, taken from the skin and flesh of red apples grown in New York State. They studied the effectiveness of the apple extracts in fighting cancer.

The researchers treated colon⁹ (结肠) cancer cells with fifty milligrams of apple extract⁷ (苹果汁). Extracts from the apple skin reduced the growth of cancer cells by forty-three percent. Extracts from the fruit's flesh reduced the growth of cancer cells by twenty-nine percent.

The researchers also treated human liver¹⁰ (肝) cancer cells with apple extract. Extracts from the apple skin reduced the growth of those cells by fifty-seven percent. Extracts from the fleshy part of the apple reduced the cancer cells by forty percent.

Lead researcher Liu Ruihai said scientists have long known that apples are good for human health. He says some scientists are interested in testing single vitamins or other substances to see if they alone fight disease¹¹. He says his study shows no single substance works¹² alone to reduce cancer. Instead, the combination of chemicals in apples is effective and eating fruit and vegetables is better than taking extra vitamin pills.
