NCT ID NCT07734948
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This trial investigates whether eating purple-fleshed potatoes daily for four weeks can improve blood pressure and other heart health markers in men with prehypertension. Participants will consume either purple or white potato puree in a crossover design, with measurements taken before and after each period. The study aims to see if the anthocyanins—compounds that give purple potatoes their color—offer cardiovascular benefits.
