British Journal of Nutrition Meta-Analysis Associates 28g Daily Nuts With 20% Lower Hypertension Incidence
Observational meta-analysis of eight cohorts links modest daily nut intake to lower hypertension risk but cannot establish causation. Benefits appear plateaued around 30g and depend on low-sodium preparation. RCTs with hard endpoints are needed to confirm effects.
Next-step research requires long-term randomized controlled trials that isolate nut supplementation, measure ambulatory blood pressure as primary endpoint, and control for overall diet quality. Such trials would clarify whether the observed 20% relative risk reduction translates into clinically meaningful absolute reductions in hypertension incidence over five years.
VITALIS: An adequately powered RCT of 30g daily unsalted mixed nuts will report no greater than 3 mmHg mean systolic reduction versus control at 12 months in adults with elevated blood pressure.
