Rote-Bete-Saft-Nitrat gegen Placebo und Blutdruck in einer 4-Wochen-Studie

A randomized, double-blind, placebo-controlled trial published in Hypertension in 2015 enrolled 68 adults with hypertension and randomized them to drink 250 milliliters per day of nitrate-rich beetroot juice — containing approximately 8.5 millimoles of inorganic nitrate — or the same volume of nitrate-depleted beetroot juice as placebo, for four weeks. Adults in the nitrate group showed a 7.7-millimeter-of-mercury reduction in 24-hour ambulatory systolic blood pressure and a 2.4-millimeter reduction in diastolic blood pressure compared to placebo. Endothelial function, measured by flow-mediated dilation, significantly improved. Arterial stiffness, measured by pulse wave velocity, significantly decreased. There were no serious adverse events. The mechanism: inorganic nitrate from food is reduced by bacterial enzymes in the mouth to nitrite, which is then further reduced to nitric oxide in tissues under hypoxic conditions — producing vasodilation and blood pressure reduction through a pathway that costs nothing to activate with a dietary change toward leafy green vegetables. Hypertension — blood pressure elevated above the normal threshold — is the most prevalent modifiable cardiovascular risk factor in adults over sixty-five, affecting approximately seventy to seventy-five percent of this age group in Western populations. Blood pressure management options range from lifestyle changes — weight reduction, dietary sodium restriction, exercise, alcohol reduction — to multiple classes of pharmacological agents, each with their own efficacy, side effect, and cost profiles. The inorganic nitrate pathway — nitrate from food reduced by oral bacteria to nitrite, and then t --- Paper cited: Dietary Inorganic Nitrate Provides Sustained Blood-Pressure-Lowering Efficacy: A Randomized, Phase 2, Double-Blind, Placebo-Controlled Study Authors: Kapil V, Khambata RS, Robertson A, Caulfield MJ, Ahluwalia A Journal: Hypertension Year: 2015 DOI: 10.1161/HYPERTENSIONAHA.114.04675 --- Subscribe for one peer-reviewed paper made practical, every Tuesday and Friday.
