A diet designed for puerto rico: can traditional foods fight heart disease and diabetes?
NCT ID NCT05962372
First seen Jul 28, 2026 · Last updated Jul 29, 2026 · Updated 1 time
Summary
This trial tests whether a diet adapted to Puerto Rican culture can lower the risk of heart disease, type 2 diabetes, and obesity. Researchers will compare culturally tailored nutrition advice—emphasizing traditional healthy foods and limiting unhealthy ones—with standard healthy eating guidelines. The study enrolls 250 adults aged 30–65 in Puerto Rico who have at least one risk factor like high blood pressure, high blood sugar, or excess weight.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- culturally tailored food and diet advice
- What this could lead to
- If it works, this could point toward a practical, culturally appropriate diet plan that reduces heart disease, diabetes, and obesity risks in Puerto Rican adults.
- What could go wrong
- This is a behavioral intervention trial with 250 participants, so results may not apply broadly. Diet changes can be hard to sustain long-term, and the study relies on self-reported data.
