The blood pressure-lowering effect of the DASH combination diet is significantly greater in African Americans and individuals with hypertension compared to whites and normotensive individuals.
If you are African American or have high blood pressure, the DASH diet (high fruits/veggies/low-fat dairy, low saturated fat) will likely lower your blood pressure much more than it would for a white person or someone with normal blood pressure.

The combination diet lowered systolic blood pressure significantly more in African Americans (6.8 mm Hg) than in whites (3.0 mm Hg), and in hypertensive subjects (11.4 mm Hg) than in nonhypertensive subjects (3.4 mm Hg) (P<.05 for both interactions).
