| Research Abstract |
To test the hypothesis that food enriched with Okinawan vegetable would improve health indexes, we investigated effects of Okinawan vegetable-rich diet on those indexes in Americans who live in Okinawa and Japanese who live in Tokyo area with a prospective randomized-controlled study. Okinawan vegetable-rich diet caused a significant reduction of blood pressure and body weight with a reduction of urinary salt excretion by about 3g. Okinawan vegetable-rich diet decreased body weight and blood pressure. In addition it improved urinary albumin excretion and circulating endothelial progenitor cells, a marker of vascular function. Diet intervention of vegetable rich diet may be a new strategy for improving life style modification.
