Summary

This pilot study tests whether the DASH diet, lifestyle advice, or a combination of both can lower blood pressure in adults with prehypertension—a condition where blood pressure is higher than normal but not yet in the high blood pressure range. Researchers randomly assigned 32 participants to receive either verbal lifestyle advice, a personalized DASH diet plan, or both, and tracked their blood pressure over two months. The goal is to see if these non-drug approaches can help control blood pressure and potentially prevent the need for medication.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
DASH diet and lifestyle modification advice
What this could lead to
If effective, this approach could offer a drug-free way to manage prehypertension and prevent progression to high blood pressure.
What could go wrong
This is a small pilot study with only 32 participants, so results may not apply broadly. The interventions require sustained behavior change, which can be hard to maintain.
