Physical activity increases gut motility moving waste through the gut faster. A recent study suggests the answer may be in the blood itself.  Apparently, exercise increase inflammation in the bloodstream and as a result, they see fewer cancer cells. While this is just preliminary science, it may give us the basics for how the body reduces cancer on its own, with physical activity. Is it possible that the increased occurrence of cancer in todays population may be due to a reduction of activity? Check out the NY Times article below
