Summary:
In African American adults at risk for type 2 diabetes, adherence to unmodified dietary patterns from the United States Dietary Guidelines (Healthy US, Mediterranean, Vegetarian) significantly highlighted the need for culturally relevant adaptations and elicited both barriers and facilitators to dietary change compared to standard USDG implementation without cultural contextualization, though it was associated with limited cultural relevance and acceptability in this population.
| PICO | Description |
|---|---|
| Population | African American adults (n=42), aged 26–65 years, residing in the Southeastern United States, participating in a 12-week dietary intervention aimed at reducing type 2 diabetes risk. |
| Intervention | Adoption of one of three unmodified U.S. Dietary Guidelines-based dietary patterns: Healthy US, Mediterranean, or Vegetarian diets over a 12-week period. |
| Comparison | Standard presentation of the U.S. Dietary Guidelines without cultural tailoring or contextual adaptation for African American populations. |
| Outcome | Participants reported that while the interventions increased awareness of healthy eating, there were key cultural and practical barriers to adherence. The findings highlighted the importance of adapting federal dietary guidelines to enhance cultural relevance, acceptability, and long-term adherence among African Americans. |
