The food economy is broken into its four major sectors:, food processing, wholesale grocery, retail supermarket, and restaurant. Industry incremental effects are not significantly different between low and high performers except in processing. On average, high performance has been more sustainable than low performance. Corporate and segment sustainability rates were larger for high performers as compared to low performers.
