The Case for Supermarket RDs

May 22, 2019

While I was a dietitian working at Harvard University, often times, I would run into existing and former patients (students, faculty, staff, etc.) while grocery shopping or dining in the local environs of Harvard Square. Although my food and dining choices vary just like anyone else, it was these “teachable” moments that influenced my decision to offer patients the opportunity to meet for a session in their preferred supermarket in the nearby area. After dozens of these in-store nutrition counseling sessions, my passion for using the supermarket as a learning laboratory became the inspiration for the name of my private practice for nearly a decade in Boston: Neighborhood Nutrition. In addition, it also fueled my desire to pursue a career working in the food retail space. In fact, I left my position at Harvard to work as a corporate supermarket dietitian for an independent grocery store chain based in Arizona.

Supermarket RDs Bring Trusted Expertise

Today, there are more than 800 retail RDs employed in the US at both the corporate, in-store and regional levels. In my experience, offering food and nutrition education where food purchase decisions are being made is extremely powerful in improving healthy informed choices. Consumer’s lives are busy and complex, yet most people have something in common – if healthy eating is affordable, tastes good and is convenient, they will buy it. Supermarket RDs know their customers and they engage them at precisely the right moment.

According to a 2018 survey conducted by the International Food Information Council, 80% of consumers indicate they made a change to their eating habits as a result of a conversation with a healthcare professionaland dietitians were listed as one of the most trusted sources.

On par with professional pharmacists, Registered Dietitians (RDs) have degrees in nutrition science and have also completed specialized training and passed a board examination in order to place the R.D. initials behind their name. The credentials are earned through specific educational and training requirements set forth by the Academy of Nutrition and Dietetics. In order to maintain the RD credential, dietitians are also required to earn 75 continuing education credit hours over a 5-year cycle throughout their entire career.

The Best Supermarkets Employ RDs

Health clinics, on-site experts offering diet, nutrition and other advisory services are becoming popular differentiators for retailers, according to a survey conducted by the Consumer Goods Forum.

In an era when consumers demand convenience, personalized experiences and immediate answers, retail RDs help supermarkets deliver on shopper’s expectations. What is more, their scientific training and credentials support customers’ trust and boost their store’s cachet.

Supermarket RDs benefit all players

It gives me a thrill every time I think of it — supermarket RDs are one of those rare cases where everyone wins. Retailers win through increased sales volume, improved customer loyalty, and engagement as well as corporate-wide commitments to wellness. Healthy brands and commodities like fresh produce and seafood win as RDs feature them and provide solutions to customers on how and why to incorporate them into a healthy lifestyle. Most importantly, everyday shoppers win. They get answers to their nutritional questions, solutions for their individual needs and conditions, and a convenient personalized experience designed to make the healthy choice the easy choice.
