After the first heart attack, how long were the protective factors of a Mediterranean diet maintained according to the Lyon Diet Heart Study?

The Lyon Diet Heart Study demonstrated that the protective factors associated with a Mediterranean diet were maintained for an impressive duration of four years following an initial heart attack. This remarkable finding highlights the long-term benefits of dietary interventions in cardiovascular health.

After a heart attack, implementing a Mediterranean diet, which is rich in fruits, vegetables, whole grains, fish, and healthy fats, has been shown to significantly reduce the risk of subsequent events. The four-year maintenance of protective factors indicates that the dietary changes had a lasting impact on the participants' health, emphasizing the importance of sustained adherence to a heart-healthy diet in improving outcomes for individuals recovering from a cardiac event. This study strongly supports the role of lifestyle and nutrition in secondary prevention of heart disease.
