“…The other cohort study was conducted in France (SU.VI.MAX; SUpplementation en VItamines et Minéraux AntioXydants study) and included 2341 men and women followed-up for 5?4 years. They reported that the DASH pattern was inversely associated with changes in average BP, but no assessment was reported about the incidence of hypertension (7) . We are aware that our study has some limitations.…”

Objective: To study the association between adherence to several a priori-defined healthy food patterns and the risk of hypertension. Design: Prospective, multipurpose, dynamic cohort study (recruitment permanently open). We followed up 10 800 men and women (all of them university graduates), who were initially free of hypertension, for a variable period (range 2-6 years, median 4?6 years). During follow-up, 640 participants reported a new medical diagnosis of hypertension. Baseline diet was assessed using a validated 136-item FFQ. Validated information about non-dietary potential confounders was also gathered. We calculated adherence to fifteen different hypothesisoriented food patterns and assessed the association between each of them and incident hypertension using multivariable Cox models. Setting: The SUN (Seguimiento Universidad de Navarra -University of Navarra Follow-up) Project, Spain. Subjects: Participants recruited to the SUN cohort before October 2005 were eligible for inclusion; after excluding those with self-reported hypertension or CVD at baseline, or with extreme total energy intake, data of 10 800 were analysed. Results: Higher adherence to the DASH (Dietary Approaches to Stop Hypertension) diet (range of the score: 0 to 5) was significantly associated with a lower risk for developing hypertension (P for trend 5 0?02). The other food patterns showed no significant association with incident hypertension. Conclusions: Our results support a long-term protection of the DASH diet against the incidence of hypertension, but we found no evidence of a similar inverse association with hypertension for any other a priori-defined healthy food pattern.

Dairy Consumption and Incidence of Hypertension

H ypertension (HTN) contributes to approximately half of all cardiovascular diseases.1 In 2000, the worldwide prevalence of HTN was estimated to be 26%, affecting ≈1 billion people. It is expected that 29% of the world population will be experiencing HTN in 2025, mainly because of the expected increase in hypertensive people in economically developing regions. 2American and European guidelines emphasize the importance of weight control, regular physical activity, moderate alcohol intake, and reduced sodium intake for the prevention of HTN and cardiovascular diseases. 3,4 A diet low in saturated and total fat and rich in fruit, vegetables, and low-fat dairy products substantially lowered blood pressure (BP) in the Dietary Approaches to Stop Hypertension (DASH) Trial. 5 Dairy products contain protein, minerals (eg, calcium, potassium, magnesium, and phosphorus), and vitamins (eg, folate and vitamin D, if fortified) that may individually or in combination reduce BP. [6][7][8] A recent meta-analysis of 5 prospective cohort studies showed significant inverse associations of total dairy, low-fat dairy, and fluid dairy foods with BP. 9 However, large variation in the types of dairy intake and serving sizes exists among populations, which has not yet been fully explored. Therefore, we conducted a dose-response meta-analysis of 9 populationbased cohort studies in which we examined total dairy, low-fat dairy, high-fat dairy, and different types of dairy products in relation to incidence of HTN. Methods Study SelectionA systematic literature search was conducted for articles on dairy consumption and BP or HTN, which were published until July 2011, using the databases of PubMed (www.ncbi.nlm.nih.gov/pubmed), Embase (www.embase.com), and Scopus (www.scopus.com). Titles and abstracts were screened to select prospective studies on dairy intake and HTN or BP changes over time. We identified a total of 1709 unique articles, from which we excluded animal studies, in vitro studies, comments, letters, editorials, ecological studies, and randomized controlled trials. Studies in children, adolescents and pregnant women, patients, and hypertensive populations were also excluded. Additional articles were found by checking bibliographies of cohort studies and reviews.Abstract-Observational and clinical studies suggest that dairy intake, particularly low-fat dairy, could have a beneficial effect on blood pressure. We performed a dose-response meta-analysis of prospective cohort studies on dairy intake and risk of hypertension in the general population. A systematic literature search for eligible studies was conducted until July 2011, using literature databases and hand search. Study-specific dose-response associations were computed according to the generalized least squares for trend estimation method, and linear and piecewise regression models were created. Random-effects models were performed with summarized dose-response data. We included 9 studies with a sample size of 57 256, a total of 15 367 incident hypertension cases, and a...

“…Participants from the SU.VI.MAX (Supplementation en Vitamines et Minéraux Antioxydants) cohort who achieved the current daily fruit and vegetable intake recommendations within the DASH diet guidelines presented a lower increase in blood pressure with aging (Dauchet et al, 2007). In addition, a prospective study in the EPIC (European Prospective Investigation into Cancer and Nutrition) cohort evidenced that a high vegetables, legumes, and fruit diet was associated with a reduced risk of all-cause mortality, especially deaths due to cardiovascular disease underling the recommendation for the diabetic population to eat large amounts of vegetables, legumes, and fruit (Nothlings et al, 2008).…”

Oxidative Stress and Diseases

Oxidative Stress and Diseases 544 reactive species: reactive oxygen species (ROS, thus, oxygen-containing molecules that are highly reactive), reactive chlorine species (RCN) and reactive nitrogen species (RNS). All these reactants contain free radicals as well as nonradicals. Low concentrations of these reactive species are necessary for normal cell redox status, cell function and intracellular signalling (Droge, 2002;Valko et al., 2007;Perez-Matute et al., 2009). However, in some disease states, free radicals are produced in excess and can damage DNA, proteins, carbohydrates and lipid constituents and compromise cell function leading to the development of type 2 diabetes, atherosclerosis, obesity, arthritis etc. Thus, it is clear that excessive production of free radicals causes damage to biological material and is an essential event in the aetiopathogenesis of various diseases. However, the question that has risen in the past years is whether uncontrolled formation of ROS is a primary cause or a downstream consequence of the pathological processes. In other words, it is still not clear what comes first, the chicken or the egg. However, what is clear is that there must be a balance between these reactive species and the antioxidants, whose main function is to counteract the deleterious effects of these reactive species. In fact, antioxidant is defined as any substance that when present at low concentrations compared with those of an oxidizable substrate, significantly delays or prevents oxidation of that substrate (Halliwell & Gutteridge, 1999). These defences include both enzymatic (superoxide dismutases, glutathione peroxidase, catalase, thioredoxin) and non-enzimatic systems (vitamins such as vitamin C, E, A, minerals such as selenium, zinc, cooper, bilirrubine, uric acid, some aminoacids etc).Several studies have demonstrated an increased oxidative state (either caused by an increased ROS production or diminished levels of antioxidants) in serious pathologies such as obesity, cardiovascular diseases, metabolic syndrome, cancer etc. Thus, oxidative stress actually may be related with the mentioned processes. In this context, it is tempting to suggest that if oxidative damage significantly contributes to disease pathology, then, actions that decrease it (via decreasing ROS production or increasing endogenous levels of antioxidants) might be therapeutically beneficial. In fact, attenuation or complete suppression of oxidative stress as a way to improve several diseases has flourished as one of the main challenges of research in the last years. Thus, several approaches have been carried out in order to either decrease the high levels of ROS generated or boost the endogenous levels of antioxiants. Inhibition of ROS production through the development of inhibitors (natural or chemical) against the main sources of ROS generation offers an interesting approach. Thus, NADPH oxidase and mitochondria have been postulated as the main targets to reduce ROS production (reviewed by Pérez-Matute et al., 2009). Another str...
