avocado and Reduced Diastolic Blood Pressure

Research synthesisLow evidenceSmall effect3 studies · 1 beneficial · 2 neutral · 0 harmful

Across 3 studies, 1 reported a small beneficial effect on diastolic blood pressure, while 2 found neutral effects. The predominant effect size is small. The most studied dose is 1 avocado daily, and the populations include adults with abdominal obesity or elevated triglycerides. Effects were observed in a 6-month trial, but a shorter 21-day trial showed no significant change.

  • Effective dose range: 1 avocado per day (approximately 180 g or 300 kcal)
  • Studied populations: Adults with abdominal obesity or elevated triglycerides (cardiometabolic risk factors)

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Many of the included studies did not reach statistical significance, suggesting the effect may be small or inconsistent. The beneficial effect was observed in a 6-month trial, while a shorter 21-day trial found no effect, indicating that duration of consumption may be important.
