Effects of the Mediterranean Diet on Cardiovascular Risk Profile in Men and Women

Nutritional interventions promoting the adoption of the traditional Mediterranean diet (MedDiet) are known to have significant and beneficial effects on cardiovascular disease (CVD) risk profile. On the other hand, recent evidence suggests that women respond differently to diet than men. No study has yet compared men and women metabolic response to the MedDiet in a controlled metabolic context in which all foods and drinks consumed are provided to the participant prepared by the research team. Therefore, we do not know whether being fed a MedDiet in controlled conditions would have similar health benefits in men and women. The purpose of this study is to document differences between men and women in changes in metabolic variables associated with cardiovascular risk in response to a 4 weeks isocaloric controlled nutritional intervention based on the MedDiet in which all foods and drinks are provided to subjects. We hypothesize that the decrease in LDL-cholesterol will be more important in men than in women. In this parallel controlled trial, both men and women are assigned to the same 4 weeks experimental diet formulated to be concordant with characteristics of the traditional MedDiet. Data will be collected before and after the controlled nutritional intervention based on the MedDiet.
