Sustainablility is foremost in the minds of many right now, but how grocery shoppers are prioritizing what's most important to them in this regard may be surprising to some.

"It isn't so much that a product needs to be sustainable or sustainably sourced," notes Barbara Connors, vice president of commercial insights at 84.51°.

The biggest thing they want to do is be responsible about buying the right amount of food and working their way through it."
