ESTRUCH, Ramón. Cardiovascular mortality: how can it be prevented?. Nefrología (Madr.) [online]. 2014, vol.34, n.5, pp.561-569. ISSN 1989-2284.  https://dx.doi.org/10.3265/Nefrologia.pre2014.Apr.12481.

The first step in the prevention and treatment of many chronic diseases such as cardiovascular diseases is to follow a healthy diet. Several epidemiological studies have observed that following a traditional Mediterranean diet reduces overall and cardiovascular mortality, as well as the incidence of chronic diseases such as cardiovascular diseases, cancer and neurodegenerative diseases. However, up to now, only one study has analysed the effects of the Mediterranean diet on the primary prevention of cardiovascular disease, the PREDIMED (PREvención con DIeta MEDiterránea) study. This trial included 7447 high vascular risk individuals who were randomly divided into three dietary intervention groups: Mediterranean diet supplemented with extra-virgin olive oil, Mediterranean diet supplemented with nuts, and a control diet (low in all types of fat). Analyses of intermediate markers demonstrated beneficial effects of the Mediterranean diet on blood pressure, lipid profile, lipoprotein particles, oxidative stress and inflammation markers and carotid atherosclerosis. However, the most important finding was the 30% reduction in the relative risk of major cardiovascular complications (heart attack, stroke and cardiovascular mortality) in both Mediterranean diet groups compared to those who followed a low-fat diet. The results of the PREDIMED trial demonstrate that a high unsaturated fat, antioxidant and anti-inflammatory diet plan such as the Mediterranean diet is a useful tool in reducing overall mortality and in preventing cardiovascular disease.
