A study presented at the American College of Cardiology conference found that a cohort of Black and Hispanic adults who followed a culturally-tailored DASH diet regimen, including one-on-one guidance from dietitians, saw a drop in blood pressure that was double the rate of those who used other methods. The DASH diet program focuses on fruits, vegetables, nuts, whole grains, and lean proteins, while limiting salt, sugar, saturated fats, and processed foods.

Why it matters

Nearly half of all U.S. adults have hypertension, which leads to heart disease, stroke, and other cardiovascular diseases. Black adults are more likely to have severe cases of the disease and develop it at a younger age. This study demonstrates that providing culturally-relevant dietary guidance and access to healthy foods can be an effective way to help manage high blood pressure in underserved communities.

The details

The researchers conducted a pilot trial with 80 Maryland adults who have hypertension, were aged 55 on average, and live in areas with limited access to fresh produce. Half of the participants received a $30 bag of produce plus one-on-one sessions with a dietitian every other week to discuss meal planning and heart-healthy strategies. The other half received the produce but no additional guidance. At the end of the 24-week trial, the participants who got both the counseling and the fresh produce saw double the decrease in their systolic blood pressure compared to the other group.

  • The study was presented on Monday at the American College of Cardiology conference held in New Orleans.
  • The 24-week trial took place in 2026.

What they’re saying

“We asked, 'What if we actually prescribe what they should eat, give it to them, coach them on how to prepare those foods in ways that reflect their culture and taste preferences, and then see whether they will be more likely to sustain the change going forward?'”

— Dr. Oluwabunmi Ogungbe, Lead author of the study

“This information is really actionable for clinicians, because they can tell patients, your blood pressure is more likely to be lowered if you have the right support in place—the ability to access and afford healthy foods, the confidence to cook with them, culturally aligned guidance from someone who understands your background, and consistent encouragement along the way.”

— Dr. Oluwabunmi Ogungbe, Lead author of the study

What’s next

The researchers said a larger study would be needed to help confirm these findings and further explore the effectiveness of culturally-tailored dietary interventions for managing high blood pressure.

The takeaway

This study highlights the importance of providing culturally-relevant dietary guidance and access to healthy foods as an effective way to help manage high blood pressure in underserved communities, where heart disease and stroke disproportionately impact Black and Hispanic adults.
