Are Expiration Dates On Food Reliable?

I admit that before I buy a lot of things at the grocery store, I look at the expiration date. This is especially true when it comes to milk and other fresh items. I've always wondered how accurate these dates actually are and after watching this video, I'm even more suspicious.

It's easy to tell when things like chips are past their prime as they get stale, fruit shrivels up, and bread grows mold which is an obvious cue to throw it out. However, with many items many people use the expiration date to guide them.

Watch this video's take on expiration dates and let me know if it changes the way you look at them.
