ABSTRACT To verify the effects of fish oil and soy on nitric oxide (NO) and blood pressure in patients with metabolic syndrome (MS).
Sixty women with MS were investigated in a parallel randomized design study. The first group maintained their usual diet; the second group received 25 g/day of soy; the third group received 3 g/day of n-3 fatty acids, and the fourth group the same amount previously cited of n-3 fatty acids and soy.
Serum nitric oxide metabolites showed significant increase after 90 days in the fish oil and soy groups. Systolic pressure reduced after 45 days of treatment with fish oil, whereas diastolic pressure decreased significantly throughout the study in the soy group.
NO increase and blood pressure reduction with fish oil or soy protein reinforce the importance of the influence of NO on blood pressure in patients with MS.

    ABSTRACT: The metabolic syndrome (MetS) is a clustering of risk factors for the development of cardiovascular disease and type 2 diabetes mellitus. These risk factors include raised blood pressure, dyslipidemia (raised triglycerides and lowered high-density lipoprotein cholesterol), raised fasting glucose, and central obesity. MetS has become a serious public health and clinical problem whose prevalence and incidence are increasing along with the worldwide rise in rates of obesity and sedentary lifestyles. A number of studies have shown that MetS is associated with a state of low-grade inflammation, characterized by abnormal pro-inflammatory cytokine production, increased acute-phase reactants, and activation of a network of inflammatory signalling pathways. Moreover, MetS has also been linked to oxidative stress, a consequence of a reduction in the antioxidant systems and an increase in the production of reactive oxygen species. Nevertheless, agreement exists that dietary intervention may modulate the pro-inflammatory state and lessen oxidative stress related to MetS, thereby decreasing the cardiovascular risk. In this review we address the current available evidence regarding dietary modulation of inflammation and oxidative stress associated with MetS.

    ABSTRACT: Soy drink replacement in the diet might have beneficial effects on anthropometric and blood pressure values for overweight and obese subjects. Therefore, we are going to determine the effects of soy drink replacements on the weight, waist circumference and blood pressure among overweight and obese female youths. This was a cross-over randomized clinical trial on 23 overweight and obese female subjects. All patients were on a weight reducing diet. There were two trial periods for six weeks (soy drink period and cow's milk period) and a washout period for 3 weeks. In the soy drink period only one glass of soy drink (240 cc) was consumed instead of one glass of cow's milk. The mean age of the patients was 22±2 years. Mean of BMI was 28.1±0.5. Weight and waist circumference did not changed significantly after the soy drink period compared to the cow's milk period. Systolic blood pressure reduced significantly following the soy drink period (mean percent change in soy drink period: -4.0±0.9 vs -1.7±0.5 in the cow's milk period; p<0.05). Diastolic blood pressure also reduced in the soy drink period (-0.4±0.1 vs 0.4±0.1; p<0.05). Soy drink replacement could reduce both systolic and diastolic blood pressure among overweight and obese female youths. However, this replacement had no significant results on weight and waist circumference.

    ABSTRACT: Blood pressure (BP), hypertension (HT) and cardiovascular disease (CVD) are common complex phenotypes, which are affected by multiple genetic and environmental factors. This article describes recent genome-wide association studies (GWAS) that have reported causative variants for BP/HT and CVD/heart traits and analyzes the overlapping associated gene polymorphisms. It also examines potential replication of findings from the HyperGEN data on African Americans and whites. Several genes involved in BP/HT regulation also appear to be involved in CVD. A better picture is emerging, with overlapping hot-spot regions and with interconnected pathways between BP/HT and CVD. A systemic approach to full understanding of BP/HT and CVD development and their progression to disease may lead to the identification of gene targets and pathways for the development of novel therapeutic interventions.
