Anestimated43billionpoundsoffoodwerewastedinUSretailstores
in2010.Thisisparticularlydisconcertinggiventhatin2016,12.3
percentofAmericanhouseholdswerefoodinsecure.Mostoftheloss
inretailoperationsisinperishables,includingbakedgoods,produce,
meat,seafoodandpreparedmeals.TheUSDAestimatesthat
supermarketslose$15billionannuallyinunsoldfruitandvegetables
alone.Unfortunately,wastefulpracticesintheretailindustryare
oftenviewedasgoodbusinessstrategies.Someofthemaindriversfor
foodlossatretailstoresinclude:overstockedproductdisplays,
expectationofcosmeticperfectionoffruits,vegetablesandother
foods,oversizedpackages,theavailabilityofpreparedfooduntil

hospitals一generateanadditional7to11billionpoundsper

UniversityFoodandBrandLab,onaverage,dinersleave17percentof

restaurant.Thisispartlyduetothefactthatportionsizeshave
increasedsignificantlyoverthepast30years,oftenbeingtwoto

3.DateLabelConfusion——Anestimated80percentofAmericans
prematurelydiscardfoodduetoconfusionoverthemeaningofdate
labels(e.g.,“sellby,”“bestifusedby,““expiresby,"and
soforth).Inreality,“sellby"and"useby“datesarenot

4.Overbuying一Salesonunusualproductsandpromotionsthat
encourageimpulseandbulkfoodpurchasesatretailstoresoften
