Effects of Okinawan vegetables on blood pressure, pulse wave, renal function and oxidative stress : a prospective randomized study

为了验证富含冲绳蔬菜的食物会改善健康指数的假设，我们采用前瞻性随机对照研究，调查了富含蔬菜的冲绳饮食对居住在冲绳的美国人和生活在东京地区的日本人的健康指数的影响。冲绳县富含蔬菜的饮食使血压和体重显着降低，尿盐排泄量减少约3g。冲绳人富含蔬菜的饮食可以降低体重和血压。此外，它还改善了尿白蛋白排泄和循环内皮祖细胞，这是血管功能的标志。丰富蔬菜饮食的饮食干预可能是改善生活方式改变的新策略。

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.
