Cancer-Fighting Ingredients in Apples and Carrots
Two new studies confirm the cancer-fighting power of plant foods. Scientists
at Cornell University performed laboratory tests on human colon cancer cells
and found that apple skin inhibited the growth of cancer cells by 43 percent.
Tests on liver cancer cells were even more effective. Researchers believe it
is the combination of phytochemicals in plant foods that reduces cancer.
It's no surprise that the second study also found carrots to be
high in antioxidants, compounds that prevent free radicals from
damaging cells and causing diseases such as cancer. However, scientists
found that cooking and puréeing carrots increases their
antioxidant level more than three times. Researchers report that
heating and softening the carrot's tissue allows cancer-fighting
phenolic compounds attached to the cell wall to be released. And,
keeping the outer skin on carrots, as with other vegetables and
fruits, retains numerous extra cancer-fighting compounds.
