Data_Sheet_1_A Double-Blind Placebo-Controlled Crossover Study of the Effect of Beetroot Juice Containing Dietary Nitrate on Aortic and Brachial Blood Pressure Over 24 h.docx

Dietary inorganic nitrate in beetroot can act as a source of nitric oxide and has been reported to lower brachial blood pressure (BP). This study examined the effect of inorganic nitrate in beetroot juice on aortic (central) BP acutely and over the subsequent 24-h period. A double blind, randomized, placebo-controlled crossover trial was performed in fifteen healthy, normotensive men and women (age 22–40 years). Participants were randomized to receive beetroot juice containing nitrate (6.5–7.3 mmol) or placebo beetroot juice from which nitrate had been removed (

甜菜根中的膳食无机硝酸盐可作为一氧化氮的来源，并已被报道可降低肱动脉血压（BP）。本研究旨在探讨甜菜根汁中无机硝酸盐对主动脉（中心）血压的急性影响及随后的24小时期间的影响。一项双盲、随机、安慰剂对照交叉试验在15名健康、血压正常的男性（22-40岁）和女性身上进行。参与者被随机分配接受含有硝酸盐的甜菜根汁（6.5-7.3 mmol）或已去除硝酸盐的安慰剂甜菜根汁。
