High Soy Products intake group shows Mortality Rate Risk of Stomach Cancer reduced by half

The 'Takayama Cohort' study conducted by Gifu University School of Medicine is a prospective cohort study on 30,000 citizens of Takayama city, Gifu prefecture.
The research was started in 1992, and 7 years later in 1999, a follow-up was conducted to find the dietary habits of the subjects who died from stomach cancer, and analyzed the correlations (as a matter of course, other factors providing effects or causing interference on stomach cancer were calculated and exempted at the examinations.)
By the volume of soy products intake, they were divided into 3 groups (Low, Middle and High) and the relation with death from stomach cancer was examined. If the number of deaths from stomach cancer in the low soy products intake group is taken as 1, in the high intake group the relative hazard ratio is approximately just less than 0.5 (men 0.50, women 0.49), and it is reported that the hazard ratio of death from stomach cancer is reduced by almost half. Similar correlation was observed even when the comparison was made by converting the intake volume into isoflavone intake volume.
