What is the effect of the DASH diet pattern on blood pressure in adults with hypertension?
-
Conclusion
The Dietary Approaches to Stop Hypertension (DASH) diet with a sodium range of 1,500mg to 2,400mg, reduced systolic blood pressure (SBP) by 2.0mmHg to 11mmHg and diastolic blood pressure (DBP) by 0.0mmHg to 9.0mmHg in overweight or obese adults with hypertension (HTN) regardless of anti-hypertensive medications. DASH plus weight loss resulted in reductions in SBP of 11mmHg to 16mmHg and DBP of 6.0mmHg to 10mmHg. There were no studies that met the search inclusion criteria for normal weight adults with HTN.

Grade: I
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.

What is the effect of the Mediterranean diet pattern on blood pressure in adults with hypertension?
-
Conclusion
Limited evidence from one randomized controlled trial reports that hypertensive adults who followed a Mediterranean diet, supplemented with either extra virgin olive oil (up to one liter per week) or nuts (30g per day) had reductions in diastolic blood pressure up 1.5mmHg greater than those following a low-fat diet.
