Diet, Stress and Cancer Risk
|
Intuitively as well as scientifically, we have a feel of how stress and diet both play large roles in cancer development. A study published in August 2008 in the International Journal of Oncology has given us some clues of how these two factors may interact to affect cancer risk.
The article below summarizes this study. A little “warning” here – things do get a little technical. However, the conclusion is relatively straightforward, giving us some tips on how to improve our diet to ward off cancer.
Study Shows Link Between Diet and Stress Induced Cancer
by Barbara Minton
(NaturalNews) Will the stress in your life cause you to develop cancer? The answer to this question may depend on what you eat according to a study published in the August, 2008 edition of the International Journal of Oncology.
Researchers examined the possible growth promoting effects of the stress-associated hormone norepinephrine on immortalized human pancreatic duct epithelial cells. The results suggested that norepinephrine can increase proliferation of these cells. They then evaluated the ability of norepinephrine to induce interleukin-6, and vascular endothelial growth factor, both believed to promote cancer of pancreatic duct epithelial cells. They found that norepinephrine can indeed increase the interleukin-6 and vascular endothelial growth factor in the cells.
Based on theses results, the researchers performed further testing to see if dietary agents sulforaphane and resveratrol can inhibit norepinephrine-mediated increases in cell proliferation. Results indicated that sulforaphane but not resveratrol inhibits the norepinephrine-mediated increases in cell proliferation. Sulforaphane also inhibited norepinephrine-mediated increase of the interleukin-6 levels of the cells.
We are living through an extremely stressful period of history. Hundreds of studies have documented how stress impacts our immune systems and ability to fight off invading organisms. This study goes a long way toward documenting the link between stress and cancer. The implications for further research are huge.
