DASH Diet for Dummies
Overview
The DASH (Dietary Approaches to Stop Hypertension) diet targets blood pressure reduction through specific nutritional targets and lifestyle modifications.
Nutritional Targets
Macronutrient Distribution:
- Total Fat: 27%
- Saturated Fat: 6%
- Protein: 18%
- Carbohydrates: 55%
Key Micronutrients:

Research Findings
The original DASH study involved 459 participants with elevated blood pressure across three diet conditions over 8 weeks. Results showed the DASH diet reduced systolic pressure by 5.5 points and diastolic by 3 points in general populations, with hypertensive individuals experiencing reductions of 11.4 and 5.5 points respectively—comparable to pharmaceutical interventions.
