Summary:
In African American adults at risk of type 2 diabetes, adherence to three unmodified dietary patterns outlined in the 2020-2025 United States Dietary Guidelines (Healthy US, Mediterranean, Vegetarian) significantly influenced perceptions and acceptability of diet modification strategies
compared to baseline dietary habits without intervention, though it was associated with challenges in cultural relevance and feasibility of long-term adherence.
| PICO | Description |
|---|---|
| Population | African American adults at risk for type 2 diabetes participating in a 12-week randomized intervention trial. |
| Intervention | Adoption of one of three dietary patterns per the 2020-2025 United States Dietary Guidelines: Healthy US, Mediterranean, or Vegetarian diet over 12 weeks. |
| Comparison | Usual dietary habits prior to intervention without modification or guideline adherence. |
| Outcome | Participants reported varying degrees of acceptability and cultural fit for each diet, with common barriers including perceived feasibility and relevance. The intervention increased awareness but highlighted the need for culturally tailored approaches to improve adoption and sustainability. |
