Long-term dietary adherence and changes in dietary intake in coronary patients after intervention with a Mediterranean diet or a low-fat diet: the CORDIOPREV randomized trial

Purpose Adherence to a healthy dietary pattern positively influences clinical outcomes in cardiovascular prevention, but long-term adherence is difficult to maintain. We evaluated 5-year changes in dietary habits, adherence achieved, and its maintenance in a cohort of coronary patients from the CORDIOPREV study.
