Diet in the primary prevention of cardiovascular diseases: PREDIMED STUDIES

01 February 2023, 14:00-15:30 CET

The Mediterranean Diet (MedDiet) is considered a model of healthy eating and has been associated to a decreased risk of several diseases and conditions using prospective cohort studies. In addition, MedDiet has demonstrated beneficial effects in several cardiovascular risk factors using randomized clinical trials. The PREDIMED trial has demonstrated that, compared to advice to adhere to a low-fat diet, a long-term intervention with MedDiet supplemented either with virgin olive oil or nuts improve different classical and emergent cardiovascular risk factors, reduces the risk of diabetes, the incidence cardiovascular disease and mortality and other chronic conditions. The PREDIMED-Plus study is an ongoing parallel group, multi-centre, randomised, primary prevention trial on men and women (55-75 years), with overweight/obesity and metabolic syndrome. The objective of PREDIMED-Plus is to compare the cardiovascular effect of two interventions: a) intensive weight-loss intervention on lifestyle program with hypocaloric MedDiet, physical activity and behavioural support, b) recommendations on MedDiet diet following the usual care of medical physicians. The principal end-points are: 1) a composite of cardiovascular events and mortality, and 2) weight loss and weight maintenance at long term. Other secondary end-points include the incidence of several chronic conditions or diseases associated to obesity and metabolic syndrome. The rationale for the new PREDIMED-Plus trial was to go a step further than the PREDIMED trial and to find out whether long term intentional weight reduction through promotion of physical activity and an energy-restricted MedDiet results in a reduction of CVD events. The main hypothesis that is being tested in this trial is that addressing energy reduction with a high-quality dietary pattern such as the MedDiet plus increased physical activity during a 6-year period, an even stronger reduction in incident CVD will be observed by comparison with that attained with a MedDiet alone in PREDIMED. We can present evidence demonstrating that the Mediterranean diet is useful in the prevention of cardiovascular disease and other health outcomes, as well as the potential mechanisms implicated.
