You simply don't want to know some of the things I know
However I will say this much -- Most best-before dates are simply the latest reasonable date that the company verified their product can last to a lab. It's cheaper to say"eh test it after 28 days and hopefully that's enough" than to say "test it every day until it's over the limits". So you can probably rest easily on a lot of best-by dates, they aren't nearly as concrete as many believe -- although that's all at your own risk
