Millions of health articles are published annually, with randomized controlled trials (RCTs) sitting atop the evidence hierarchy for assessing interventions. The reason randomized controlled trials are considered the gold standard of nutrition research is their unique ability to reduce bias and provide the strongest evidence for cause-and-effect relationships between dietary interventions and health outcomes.

A 2012 meta-analysis of randomized controlled trials found that dietary protein intake was associated with significant reductions in systolic and diastolic blood pressure. This evidence highlights the potential of dietary protein supplementation as a non-pharmacological strategy for hypertension management and prevention, leading to further investigation into the specific effects of various protein types.
