For decades, Dr. Lawrence J. Appel has helped change the way we understand one of the most powerful tools for managing blood pressure: the food we eat.
This year, the internationally recognized nutrition and hypertension researcher received the American Heart Association’s 2026 Research Achievement Award, recognizing a career of research that has helped turn nutrition science into practical steps people can take to improve their cardiovascular health. The award was presented during Scientific Sessions 2026 in Chicago on Nov. 8.
Research that changed the way we think about food and blood pressure
Dr. Appel, a professor at Johns Hopkins University School of Medicine and the Johns Hopkins Bloomberg School of Public Health, is perhaps best known for his leadership in the landmark Dietary Approaches to Stop Hypertension, or DASH, trial.
Published in 1997, the study showed that an eating pattern rich in fruits, vegetables and low-fat dairy products and lower in saturated fat could significantly reduce blood pressure. The findings helped establish the DASH eating plan as an important approach to preventing and managing high blood pressure.
His work did not stop there. Dr. Appel also contributed to the DASH-Sodium trial, which demonstrated the blood pressure benefits of reducing sodium, especially when combined with the DASH eating pattern. Decades later, that research continues to influence heart-healthy nutrition recommendations. In a 2023 American Heart Association scientific statement, the DASH-style eating pattern received a perfect score for alignment with the Association’s heart-healthy eating guidance.
Turning research into real-world impact
Throughout his career, Dr. Appel has continued exploring how nutrition and lifestyle changes can help people reduce their risk of cardiovascular and kidney disease.
His work has examined everything from weight management and physical activity to sodium reduction and blood pressure control. More recently, he helped lead the DASH4D clinical trial, which evaluated a DASH-style eating pattern designed for adults with Type 2 diabetes. The study found that combining the DASH4D dietary pattern with reduced sodium resulted in a clinically meaningful reduction in blood pressure.
That ability to translate complex science into practical strategies has been a hallmark of his career.
“Dr. Appel’s rigorous research has reinforced the direct connection between a healthy diet and high blood pressure, as well as other cardiovascular conditions,” said Dr. Manesh R. Patel, the American Heart Association’s 2026-2027 volunteer president. “His work has translated complex nutrition science into clear, actionable strategies that have improved care and helped millions of people take meaningful steps to prevent and manage high blood pressure.”
A legacy built through collaboration
Dr. Appel has authored or co-authored more than 700 scientific publications and has been a longtime American Heart Association volunteer, serving in leadership roles across the organization’s nutrition, epidemiology, hypertension and cardiometabolic health efforts.
But for Dr. Appel, the achievement reflects far more than an individual career.
“I cannot emphasize too strongly that this recognition reflects the collective efforts of numerous colleagues,” he said, crediting the participants, investigators, staff and trainees who have shared his commitment to improving the health of patients and communities.
From the landmark DASH trial to today’s research on nutrition, hypertension and chronic disease, that collective work has helped give people something incredibly valuable: evidence that everyday choices can make a meaningful difference in heart health.
