Fighting Cancer With Pineapple

Two molecules isolated from an extract of crushed pineapple stems have shown promise in fighting cancer growth. The extract studied by the scientists, bromelain, is a rich source of enzymes, and is one of the reasons why I listed pineapple as one of the top nine healthiest fruits you can eat. Here's how it works:

  • One molecule called CCS blocks a protein called Ras, which is defective in approximately 30 percent of all cancers.
  • The other, called CCZ, stimulates the body's own immune system to target and kill cancer cells.
Researchers found the extract also had pharmacological properties and could activate specific immune cells while, simultaneously, blocking the immune function of other cells.

Earlier this year, cancer passed heart disease as the leading cause of death in the United States. But it doesn't have to be this way--this disease that is so common today was actually a rarity for our ancient ancestors, and even the American Cancer Society says that more than 60 percent of the 2005 cancer deaths could have been prevented if Americans adopted healthier lifestyles, such as these 12 changes that will cut your cancer risk in half.
