One-third of supermarkets have a dietitian walking their aisles, according to a recent report published by Advertising Age. And almost 9-in-10 grocers have a dietitian housed in their corporate suites.

Is it any wonder? There's a natural synergy between pharmacy and food stores that grocers have been looking to tap in one form or another over the past decade. But now, especially as health systems and large employers become more savvy around the benefits a healthier workforce will have to their bottom lines, this is likely to transform from a supermarket patient's best-kept-secret into a must-have service.
