I don't know, sounds like one of those urban legends to me. Any proof of this correlation? Why has there been no rise in stomach cancer associated with the use of soy in other countries including the US? How do you know that any supposed rise in stomach cancer has not been caused by increased exposure to H. pylori, which HAS BEEN linked to stomach cancer unlike soy?
