Randomized Controlled Trial
Consumption of Brazil nuts with high selenium levels increased inflammation biomarkers in obese women: A randomized controlled trial.
Increased inflammatory response is an important factor in the pathophysiology of obesity. The mineral selenium (Se), of which one of the main food sources is the Brazil nut, has important antioxidant and anti-inflammatory functions through the action of selenoproteins. Thus, the evaluation of the influence of this micronutrient in this context is of great relevance. The aim of this study was to evaluate the effects of Brazil nut intake with high Se concentrations on inflammatory biomarkers and its relation to Se status in obese women. ⋯ Although there were no changes in plasma inflammatory biomarkers levels, a significant increase in gene expression may be an indication of a proinflammatory stimulus in obesity, induced by the consumption of Brazil nuts with high Se levels.

Randomized Controlled Trial
Randomized study of the effects of cocoa-rich chocolate on the ventricle-arterial coupling and vascular function of young, healthy adults.
The aim of this study was to evaluate and explore the benefits of long-term dark chocolate intake in young, healthy adults by measuring cardiovascular function. ⋯ This study demonstrated that regular consumption of HCC has beneficial effects on the cardiovascular system in young, healthy adults, improving vascular function by reducing central brachial artery pressures and promoting vascular relaxation, and thus enhancing the matching of the arterial system with the left ventricle.

The aim of this study was to determine the influence of vitamin D-binding protein (DBP) gene polymorphisms in vitamin D metabolites before and after vitamin D supplementation. ⋯ rs7041 and rs4588 variants of the DBP gene are associated with variations in 25(OH)D levels and efficacy of response to vitamin D supplementation in Saudi Arabian adults.

Meta Analysis
Dietary inflammatory index and cancer risk in the elderly: A pooled-analysis of Italian case-control studies.
The aim of this study was to evaluate whether the association between the inflammatory potential of one's diet and cancer risk varies across age groups in a population characterized by widespread use of the Mediterranean diet. ⋯ In the Italian population, DII scores were higher in elderly than in middle-aged individuals. Although not directly affecting cancer risk, this finding may have important implications for the older population because elevated DII scores, indicating a proinflammatory diet, also have been associated with frailty.

There is a higher rate of mortality from cardiovascular disease (CVD) in Iran and the mortality rate increases even after coronary artery bypass grafting (CABG). The aim of this study was to evaluate the association between mortality and survival in patients 10 y after CABG, using the dietary inflammatory index (DII) and dietary antioxidant indices. ⋯ According to the present findings, a diet high in inflammatory foods and low in antioxidant content is a potent predictor of mortality 10 y post-CABG. Therefore, reducing the inflammatory potential of the diet and improving its antioxidant content will be a preventive strategy for reducing mortality after CABG.
