Protein power: new study probes link between diet and heart risk
NCT ID NCT05470218
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how high-protein drinks affect certain blood cells (monocytes and platelets) that may play a role in heart disease. Ten healthy adults will drink either a low-protein, high-protein, or leucine-added meal, and researchers will check their blood for changes in cell activity. The goal is to understand if high-protein diets could raise heart risks, not to treat or cure any condition.
