Dietary factors associated with hypertension

Factores de riesgo cardiovascularPor: Dong Zhao, Yue Qi, Zheng Zheng, Ying Wang, Xiu-Ying Zhang, Hong-Juan Li, Hai-Hang Liu, Xiao-Ting Zhang, Jie Du y Jing Liu.  Nature Reviews Cardiology 8, 456-465 (August 2011).

Hypertension is one of the major risk factors for cardiovascular disease, with an impact on global health. Multiple studies have suggested that various dietary factors are associated with blood pressure (BP) and hypertension. The purpose of this Review is to provide up-to-date knowledge on the impact of dietary factors on BP and hypertension, to compare types and recommended intakes of dietary factors in hypertension management and prevention guidelines from different countries and organizations, and to outline global population-based healthy-diet strategies for hypertension control.

The effects of dietary patterns on plasma renin activity: results from the Dietary Approaches to Stop Hypertension trial

InvestigacionesPor:  Q Chen1, S Turban, E R Miller y L J Appel.   Journal of Human Hypertension (2012) 26, 664–669.


A diet rich in fruits, vegetables and low-fat dairy products, and reduced in saturated fat, total fat and cholesterol (the ‘DASH’ diet) significantly lowers blood pressure (BP). Previous studies have documented that certain therapies that lower BP increase plasma renin activity (PRA). Using data from the Dietary Approaches to Stop Hypertension (DASH) trial, we assessed the effects of dietary patterns on PRA and determined the relationship of change in PRA with change in BP on each diet. After eating a control diet for 3 weeks, participants were then randomized to receive for 8 weeks: the control diet, a diet rich in fruits and vegetables (F/V), or the DASH diet. Baseline and follow-up levels of PRA were available in 381 participants.  (publicado: 05–11-2012)

This survey was designed to provide data to establish progress towards meeting the Department of Health’s target to reduce the population average of dietary salt intakes to no more than 6g per day. The aim was to collect useable 24-hour urine samples from 600 respondents, representative of the population aged 19 to 64 years living in England in the second half of 2011. Urinary sodium excretion was used to estimate salt intake. Salt intake was calculated using the equation: 17.1 mmol of sodium = 1g salt and assumes all of the sodium was derived from salt.

To develop statistical models for predicting weight loss and regain, we analyzed the phenotypic responses in an outpatient study of 60 obese subjects randomized to one of three 12-week interventions, diet (–600 kcal) alone, diet with exercise, and diet with sibutramine. This was followed by 12 weeks of observation.
