The effect of dietary patterns on blood pressure control in hypertensive patients: Results from the dietary approaches to stop hypertension (DASH) trial

To determine the impact of dietary patterns on the control of hypertension we studied the subgroup of 133 participants with systolic blood pressure of 140 to 159 mm Hg and/or diastolic BP of 90 to 95 mm Hg enrolled in the Dietary Approaches to Stop Hypertension study

Scholarcy highlights

  • Nutrition-based approaches are recommended as first-line therapy for the prevention of hypertension in individuals with high normal blood pressure and to control BP in patients with Stage 1 hypertension
  • (DASH) clinical trial tested the effects of modifying whole dietary patterns in 459 persons with a diastolic BP between 80 and 95 mm Hg and systolic BP less than 160 mm Hg
  • We report the clinical characteristics of the hypertensive participants, the patterns and magnitude of BP reduction across time, and the effects of the Dietary Approaches to Stop Hypertension diets on hypertension control
  • Hypertensive participants assigned to each of the diets had similar characteristics, the combination diet group tended to have fewer blacks and more participants who reported the consumption of alcohol on a regular basis
  • Significant between-diet differences were present by the second week of intervention feeding. This detailed report on the hypertensive participants enrolled in the DASH clinical trial amplifies and extends previous reports from this study
  • The available evidence from observational studies and clinical trials does not clarify that any one nutrient is responsible for the observed BP difference between the combination diet and the fruits-and-vegetables diet
  • A diet that emphasizes fruits, vegetables, and low-fat dairy products, includes whole grains, poultry, fish, and nuts, and is reduced in fat, red meats, sweets, and sugar-containing beverages led to significant hypertension control in persons with Stage 1 hypertension
