An apple a day may keep the oncologist away.  

Naturally occurring chemicals in apples slow the growth rate of human colon-cancer cells and liver-cancer cells, laboratory tests at Cornell University have demonstrated.  

The stronger the concentration of apple extract, the slower the rate of reproduction among the cancer cells, the Cornell scientists reported in a recent edition of the journal Nature.  

The researchers said the relatively large amounts of antioxidants found in apple extract may help to explain the cancer protection provided by a diet that includes five servings of fruits and vegetables a day.  

The anti-cancer effect, a spokesman said, was strongest in extracts made from unpeeled apples, which contain more antioxidant phytochemicals. These are plant chemicals containing substances that prevent or delay deterioration caused by oxygen.
