Why You Should Skip The First Product On The Grocery Store Shelf
Grocery stores have a ton of items to keep track of, so many stores stock by expiration date. This means the item in the very front of a display likely has the soonest expiration.
Stocking this way is called the "FIFO" Method (first-in, first-out). By checking the back of the shelf, you may find a fresher product with a later expiration date.
Not every grocery store follows this rule, but it is common practice. Also, keep in mind that the date on a food label isn’t always the date that it goes bad and becomes inedible.
The dates on products usually give you an idea of when food will stop tasting its best. Still, regulations differ and the date could mean many things, so do your research.
