from time.com: Date labels on food were created with consumer safety in mind. But some of the labels result in confusion—and tons of perfectly safe food tossed out for no good reason. We hear regularly that Americans waste a colossal amount of food. One popular factoid has it that we wind up throwing out 25% of the food that comes into our homes. Over the years, experts have pointed out that Americans aren’t really trying to be wasteful; instead, we’re often misled by confusing expiration dates, or rather what we think of as expiration dates. Sites such as ShelfLifeAdvice.com try to clarify the meaning of terms such as “use by” and “sell by,” with the general takeaway being that you shouldn’t necessarily toss food out when the date stamped on a product has passed.
