Blueberries might help prevent colon cancer

Blueberries May Help Curb Colon Cancer Washington Post 3/27/07 "a natural compound called pterostilbene -- found in blueberries and other fruits -- helped prevent pre-cancerous colon lesions in rats..."Pterostilbene is an antioxidant and an anti-inflammatory agent that is mostly found in blueberries and blackberries," said study leader Bandaru Reddy...Colon cancer is one of the major cancers in Western countries, and this study is one of the first to show pterostilbene's potential to fight it...the rats who were fed pterostilbene had 57 percent fewer pre-cancerous lesions in their colon...Ingesting pterostilbene also reduced colonic cell proliferation and inhibited the expression of certain genes involved in inflammation -- both of these are considered to be risk factors for colon cancer...The next step is to further test pterostilbene in animals to see if it can prevent tumors. Only then will human trials be possible...Another study from Ohio State University found that rodents whose diets were supplemented with black raspberries had up to an 80 percent reduction in colon tumors and a 60 percent reduction in tumors of the esophagus...researchers in Germany were to report on a study that found drinking two to three glasses of cloudy (or unfiltered) apple juice a day may curb colon cancer in mice..."
