You’re on crack bud. Canned goods keep for a couple of DECADES if not more. Just because the silly soda companies put an expiration date on the bottom of the can doesn’t mean anything except they are trying to coerce you into buying a new can.
It’s really simple to tell when canned goods have gone bad...the bad ones blow up...sometimes literally. If the ends of the cans aren’t bulged out, it’s fine.
Next your going to tell me that grain and seed goes bad. Or pickles.
btw, I’ve eaten food from cans so old the labels rotted off and the cans were covered in rust. The only way to know what was in them was to open them up and taste.
I was in business for several years packing and distributing freeze dried and other food items, and was well known in my part of the country in the survival goods area. Earlier, I had a senior position with one of the largest frozen food packers in the world and worked two doors down from the tasting lab.
Why the hell do you think all the soft drinks have expiration dates, fool??? -- because the manufacturer doesn't want you to have a bad experience and be turned off from the brand.
If you are incapable of detecting the change in taste, unless the "can is so old the labels rotted off and the cans were covered in rust", I would get up off your walker, take off your oxygen mask, and ask the nearest geriatric nurse to validate the contents.
You also, quite simply, fail to distinguish between chemical changes affecting taste and biological contaminants affecting safety.
