INTRODUCTION
Diets that are consistent with the Dietary Approaches to Stop
Hypertension (DASH)6 are associated with reduced cardiometabolic
risk and better health outcomes. The design of the DASH diet,
which is rich in plant foods and low-fat dairy products and relatively
low in fats and sugars, was predicated on the notion that the
health-promoting effects of diet arise from the overall diet
rather than from individual foods or nutrients (1). In randomized
trials, DASH dietary patterns were shown to lower
blood pressure in persons with hypertension and prehypertension,
even without sodium reduction (2, 3). The beneficial effects of the
DASH diet were observed within 2 wk and, when combined with
sodium reduction, were similar in magnitude to the results of
pharmaceutical trials (1). Observational studies found associations
between DASH-accordant diets and reduced weight gain (4), lower
incidence of stroke (5), heart failure (6), and fatal cardiovascular
disease more generally (7). Accordance to DASH was also associated
with reduced risk of type 2 diabetes (8) and colorectal cancer
