Amazon's acquisition of Whole Foods has spurred its first big deal among the grocery distributors.

With United Natural Foods' $2.9 billion acquisition of Supervalu, announced Thursday, UNFI lessens its reliance on Whole Foods, a relationship that has been shrouded in uncertainty ever since Amazon acquired the natural grocer. Whole Foods accounts for roughly 33 percent of UNFI's business and has a contract with the distributor that is set to expire in 2025.
