Shopping for Health

Let me just say it:  I want to change the world. I became a Registered Dietitian (RD) because I know revolutionizing America’s eating will help solve all sorts of problems – from chronic disease to health care costs to global warming. Filling our plates with healthy and sustainable choices can improve our world one bite at a time.

While working as a dietitian for Harvard University, I learned that we need bigger solutions to reduce customer confusion and improve public health. What better place to create solutions than in the supermarket where people make most food decisions? People are hungry for trusted nutrition information.

An Introduction to Retail RD Programs

Reaching Millions of Customers

The simple fact is Supermarket RDs deliver. These credentialed, food, nutrition & retail experts provide real-time face-to-face customer solutions that are transforming health one shopping cart at a time. This is why I launched the first Supermarket Dietitian Symposium (2009-18) to bring together leaders from the top 50 retailers annually to strategize and network. Food brands and retailers that invest in improving customer health, increase profitability, loyalty, and engagement.

A former collegiate tennis player, Barb is an avid singles player and competes in the Southwest USTA. Born and raised in Bellport, NY, a small, coastal town in Eastern Long Island, her passion for food started at an early age …catching and eating local seafood and enjoying freshly picked strawberries (and shortcake).
