Research Abstract

The purpose of this study was to determine the effect of traditional vegetable -rich Okinawan diet on reducing cardiovascular risk factors. The study design was a randomized cross-over trial. We investigated whether the Okinawan diet could lower blood pressure and enhance the behavior modification of community residents through the 1-2 year- dietaryintervention trial. 611 healthy Japanese volunteers aged between 40 and 69 years old living in Yokohama/Tokyo and Okinawa were recruited for the study. The combination of a short-term and intensive orientation program through lightly salted diets and long -term promotion of sustained awareness of health through newsletters and a BDHQ can be one of the effective tools for the dietary health promotion including sodium restriction.
