What this trial studies

This observational study investigates how well patients with type 2 diabetes adhere to the Mediterranean diet over a 12-month period. Patients aged 18 and older, admitted to specific hospitals in Paris, will undergo an assessment of their eating habits and be educated on the Mediterranean diet's 14 key components. Adherence will be measured through questionnaires and biological markers, including olive oil consumption. The study aims to identify barriers to adherence and the diet's impact on various health metrics such as body weight, glucose levels, and liver enzymes.

Why it matters

Potential benefit: If successful, this study could enhance dietary adherence among patients with type 2 diabetes, potentially improving their health outcomes.

How similar studies have gone: Previous studies have shown positive effects of the Mediterranean diet on diabetes management, but this specific approach to adherence in non-Mediterranean populations is relatively novel.
