Maybe if you count the inedible parts of the food you buy as “waste”.
Sorry, but I’m not into Avocado pits.

Per household or purchasing body (as in a store or restaurant) I have my doubts. Never in my life have I dumped 3 dozen perfectly edible sandwiches in the trash on any given day.

There are a lot more households than there are stores or restaurants so in aggregate total homes may make for a greater sum, but that’s the same kind of logic they use to say people need to all switch to paper straws and forgo the AC in summer while the rich fly about in personal jets and rockets for a joyride.
