Data-guided, supermarket-based, dietary interventions and modern online shopping tools can improve diets. This article discusses the results of a three-month randomized field trial that promoted a hypertension-reducing diet. Adherence to the diet increased 3.8 - 4.7 times more for the intervention groups compared with the control.


In collaboration with a large retail supermarket chain, the authors conducted a multisite supermarket and web-based intervention targeting nutrition trial. They randomized 139 women and 108 men into one of three groups: two levels of dietary education (Strategy 1 and Strategy 2) or an enhanced control group that included educational components beyond the routine standard of care. Strategy 2 also included online tools for shopping, home delivery, selection of healthier purchases, meal planning and healthy recipes. They monitored adherence to a hypertension-reducing diet from baseline to 3 months. Adherence to the diet increased 4.7 times more for the combined Strategy 1 and Strategy 2 groups compared with the control. Strategy 2 increased adherence 3.8 times more than Strategy 1.
