Dietary nitrate from vegetables (e.g., beetroot, leafy greens) lowers blood pressure via the nitrate-nitrite-nitric oxide pathway, with effects dependent on baseline blood pressure levels.

To lower blood pressure using diet, focus on high-nitrate vegetables like rocket, spinach, beetroot, and lettuce. You can get benefits from acute doses (like a glass of beetroot juice) or daily consumption. However, if you use antibacterial mouthwash, it may block the benefit by killing the oral bacteria needed to convert nitrate into nitric oxide. The effect is most pronounced in people with higher baseline blood pressure.

GoodQualifiesHIGH confidence
Dietary nitrate has been demonstrated to have a range of beneficial vascular effects, including reducing blood pressure... strong inverse correlations were demonstrated between the peak decrease in BP and the baseline BP... dietary nitrate will be more effective in reducing blood pressure when it is needed, i.e. in people with high normal BP or hypertension

Why this rating

Supported by multiple randomized controlled trials (RCTs) and crossover studies showing dose-dependent BP reduction, though long-term hard endpoint data is lacking.
