This study aims to systematically review randomized clinical trials (RCTs) evaluated the effects of resveratrol on vascular flow-mediated dilation (FMD).
Abstract
Purpose
This study aims to systematically review randomized clinical trials (RCTs) evaluated the effects of resveratrol on vascular flow-mediated dilation (FMD).
Design/methodology/approach
All published RCTs in English were systematically searched on PubMed and Scopus search engines up to October 2017. A total of 61 studies were found through search databases. The outcome variable of interest was FMD. Six articles which met inclusion criteria were included in this study.
Findings
From six studies, four showed a significant improvement in FMD after resveratrol supplementation acutely or chronically in subjects with cardio-metabolic risk factors. Two other studies did not show any significant effect of resveratrol on FMD.
Originality/value
The authors systematically reviewed the effectiveness of resveratrol supplementation on FMD for the first time. The findings suggest that pure resveratrol supplementation may have beneficial effects on endothelium dependent vasodilatation indicator, FMD.

Abstract
Purpose
The purpose of the present study is to evaluate chocolate consumption effects with a non invasive metodology. There is evidence that the consumption of dark chocolate and cocoa with high flavonoid content could have positive effects on blood pressure (BP) and weight management (WM); however, there are complications at the moment of obtaining blood samples to evaluate on children at a primary school level.
Design/methodology/approach
A total of 54 healthy scholars were included; consumption of 70 per cent cacao dark chocolate was integrated into the daily snack during a 30-day period. Blood pressure, body fat, total content of polyphenols in urine and total antioxidant capacity of saliva were measured. The results obtained were divided in relation of two groups of students, A and B, with lesser or higher difficulties to WM in a self-assessment test; variables were then statistically evaluated.
Findings
Consumption of chocolate produced changes in the total content of polyphenols (from 5.6 to 6.8 µg/mL, p < 0.016) and salivary antioxidant capacity [(14.76 ± 5.4 and 16.14 ± 3.9) TEU nmol versus. t = 0; p < 0.029 and p < 0.001 at 15 and 30 days, respectively]. Group B, which presented higher difficulties concerning WM, presented a body fat reduction of about 0.63 per cent after chocolate consumption (p = 0.045) and a diastolic blood pressure reduction of −2.8 mm Hg in average (p < 0.025). A significant weight gain (p < 0.023) was observed only in Group A.
Research limitations/implications
Despite the reduced sensitivity of the non-invasive methodology, differences in urine and salivary content of polyphenols and antioxidant capacity suggest that the design used could be feasible, although extended studies are needed to corroborate it.
Originality/value
A non-invasive study for screening the potential health benefits of dark chocolate was assayed. The results suggest that dark chocolate consumption in children as part of the daily snack could be a complementary element in weight management and in prevention of future risk factors to chronic diseases.

This paper aims to verify the effect of 12 weeks of grape juice (GJ) consumption associated with aerobic exercise on the variation of the hypertensive elderly pressure.
Abstract
Purpose
This paper aims to verify the effect of 12 weeks of grape juice (GJ) consumption associated with aerobic exercise on the variation of the hypertensive elderly pressure.
Design/methodology/approach
A total of 45 hypertensive elderly of both sexes were distributed into: control group (CG, n = 10), exercise group (EG, n = 10), juice group (JG, n = 12) and juice and exercise group (JEG, n = 13). Blood pressure and heart rate were checked weekly before exercise in JG and JEG, and before and after intervention in all groups, with JG and JEG supplemented with 200 mL of GJ. Three weekly sessions of moderate walking were applied.
Findings
There was a reduction in EG, JG and JEG for systolic pressure and diastolic only for JG and JEG. The GJ consumption to the practice of aerobic exercise provided reductions in the arterial pressure of hypertensive, in addition to stabilization of the diastolic pressure.
Research limitations/implications
Although the objective of the study was to compare the effect and value of intervention with controls, the study had no intervention in food consumption, which could have led to more significant results. There was a limitation in the control drink, leading the study not to be blind, which may have impaired the results. However, it is probably not a bias, as the groups were divided by residence area, and therefore, had no direct contact with the other groups. Another limitation was that the sample size was still small, which would lead to more reliable results. Finally, although the existing limitations cannot be disregarded, the results of this research are very promising, especially when the objective is the effect of GJ and aerobic exercise on blood pressure, with the possibility of implementing supplemental GJ and the inclusion or not of exercise to the hypertensive elderly.
Originality/value
The paper deals with the benefits of GJ consumption associated with aerobic physical exercise on the blood pressure of elderly hypertensive patients. Considering that GJ along with physical exercise was enough to reduce the blood pressure of hypertensive elderly, this may be a new model to be used to reduce and/or control blood pressure, and GJ and the exercise to be part of the daily life of the population.

Abstract
Purpose
Emotion regulation (ER) has been identified as an important factor influencing psychological and health problems of adult populations. The purpose of this paper is to address a gap in the literature by examining available evidence relating to the use of ER strategies (avoidance, problem solving, reappraisal, rumination and suppression) on the well-being of older people (OP).
Design/methodology/approach
A systematic search for peer-reviewed articles published from 1985 to 2015 was conducted in PsycINFO, CINAHL, Medline, Psychological and Behavioural Sciences Collections and ASSIA and resulted in 1746 titles. In total, 20 studies met full inclusion criteria (the cross-sectional association between well-being and ER was reported, participants were 60 years or older, without cognitive impairment and the article was written in English, Portuguese or Spanish).
Findings
Rumination was found to be the ER strategy most strongly associated with symptoms of anxiety and depression in OP populations, while mixed result were found for avoidance, problem solving, suppression and reappraisal.
Research limitations/implications
Given the scarcity of research examining the association between ER and positive psychological concepts only a conclusion about ER and negative mood measures could be made. Questions for future research on ER and well-being in OP are proposed.
Originality/value
This paper addresses a significant gap in the literature regarding the use of ER strategies in older adults.
