How meaningful is the "use by" date on the protein bars?
A few years ago my wife was eating the Bulletproof collagen protein bars and asked me to order a few more boxes for her. I did, she stashed them in the pantry and then for whatever reason stopped eating them. I just found them, we have 3 full boxes, the use by dates are about a year ago, fall of 2017. I just wanted to check in before I throw them all out, bums me out to throw away this much food. I know with some items the "use by" date is more about maximizing enjoyment of the product than product safety. Not sure with these. They've been stored in a cool dry place the entire time.
And I've checked, they were not subject to the recall.
