Soybeans have been studied with interest in their role of cancer prevention. A study from Korea found that persons who eat the most soybean products have a decreased risk of stomach cancer. This is of special interest because stomach cancer is one of the most common causes of cancer death in oriental nations – thought to be caused largely from their high intake of salt in the diet.
This new report is a case-control study including 131 cases of stomach cancer compared to 393 matched controls without cancer. Researchers found that those eating the most soy products (determined by blood level of genistein, a marker for soy food intake) had a 46 percent decreased risk of developing stomach cancer compared to those with the lowest levels of soy intake.
