They're not perfect, but to my body, also clearly not meaningless.
Consider that food producers are logically often already under ample pressure to set those dates in reasonable thresholds on both sides by their reputations and their own supply chain lags.
I'm not saying this to be dismissive. These effects can be incredibly strong, I could not eat pork cutlets for years after I had an extremely strong migraine when I ate one. After my body associated the smell and taste with it and noped out every time I got close to one.
If anyone has more information on this I’d be very interested to read it, because it’s landed firmly in the area of … sounds legitimate, but could also be modern “old wives tale” type of stuff where people just say it because it sounds scientific enough to be true and no one has ever researched it because it’s obviously wrong scientifically speaking but is addressed by unrelated fundamental knowledge in a scientific field Im not knowledgeable about such as industrial scale food science or something else.
So yeah would greatly appreciate anything more knowledgeable people on the topic can share, this little throw away line nerd sniped me.

Anecdotally, I've had major digestive issues my entire life. It's particularly frustrating because foods that are supposed to be extremely healthy (low fodmap! gluten free! whole 30!) are still bad for me. Following the last list I posted has actually helped.
Although now that I think about it, the original poster's migraines could be caused by chemicals leaching out of the can liner.
This is a pretty thorough paper on histamine intolerance specifically, and it discusses buildup of histamines in certain foods and associated symptoms.
In reality, middle America probably grows an entire magnitude more food calories than california, and most of that is inefficiently turned into beef, or ethanol for cars. America does not need to be worried about starving. We literally throw away like a quarter of the food we purchase, and for incredibly stupid reasons like people swallowing the "Best By" dates as gospel and refusing to eat food with a bruise. This doesn't even consider the massive amount of farmland that we used to use in plenty of rural states across the nation that just aren't as profitable as the factory farms that own the markets nowadays. My state used to produce mountains of potatoes for the entire country but got outcompeted by Idaho and now is stuck growing niche crops and small batches of broccoli for local consumption.
