title: Whole versus the piecemeal approach to evaluating soy.
abstract: Soy has been singled out for attention among other legumes as a valuable source of nutrients, phytochemicals, and bioactive compounds. Early epidemiological studies established that whole soy and traditional soy foods were implicated in health-protective effects in Asian populations. The same benefits attributable to soy have not been consistently proven in Western populations that, for various reasons, opt to consume more processed soy foods or various soy components. Soy researchers continue to isolate soy components in search of identifying its salubrious components and whole soy remains relatively underinvestigated despite what we know of the health benefits it may confer to those regularly consuming it. Various dietary guidelines advocate the regular consumption of legumes that tend not to be included in our diets in sufficient quantities. This paper highlights the possibility that whole soy may have a more unique effect on health than a select soy component(s). It explores the rationale for focusing research on whole soy in an attempt to understand it better rather than trying to replicate the health benefits by targeting various soy components, which has been plagued by inconsistent results.
