Oxidative stress is associated with an increased antioxidant defense in elderly subjects: a multilevel approach.
© 2014 Fonseca et al. Background: Studies of associations between plasma GSH-Px activity and cardiovascular risk factors have been done in humans, and contradictory results have been reported. The aim of our study was to assess the association between the scavenger antioxidant enzyme glutathione peroxidase (GSH-Px) activity in plasma and the presence of novel and classical cardiovascular risk factors in elderly patients. Copyright: Methods: We performed a cross-sectional study with baseline data from a subsample of the PREDIMED (PREvención con DIeta MEDiterránea) study in Spain. Participants were 1,060 asymptomatic subjects at high risk for cardiovascular disease (CVD), aged 55 to 80, selec…
A high dietary glycemic index increases total mortality in a Mediterranean population at high cardiovascular risk
© 2014 Castro-Quezada et al. Objective: Different types of carbohydrates have diverse glycemic response, thus glycemic index (GI) and glycemic load (GL) are used to assess this variation. The impact of dietary GI and GL in all-cause mortality is unknown. The objective of this study was to estimate the association between dietary GI and GL and risk of all-cause mortality in the PREDIMED study. Material and Methods: The PREDIMED study is a randomized nutritional intervention trial for primary cardiovascular prevention based on community-dwelling men and women at high risk of cardiovascular disease. Dietary information was collected at baseline and yearly using a validated 137-item food freque…
Effects of a Mediterranean Diet and physical activity on atherothrombosis biomarkers in high cardiovascular risk individuals
Objective. Following a Mediterranean diet (MedDiet) and being physically active decrease cardiovascular risk. However, their individual and combined effects on atherothrombosis biomarkers are unexplored. Approach and Results. In 358 random volunteers from the PREDIMED trial (Prevencion con Dieta Mediterranea), we assessed the 1-year effects of an intervention with MedDiet, enriched with virgin olive oil (MedDiet-VOO; N=120) or nuts (MedDiet-Nuts; N=119) versus a low-fat control diet (N=119), on atherothrombosis markers. In a secondary, observational approach, we studied the associations of 1-year changes in MedDiet adherence, physical activity (PA) levels, and their combination, with 1-year…
