Vinegar has a similar pH to a Coke Cola. I would hazard a wild guess that the population drinks significantly more Coke than vinegar.

"as good for your teeth as Coca Cola" is a low bar.

The average consumer is not diluting their Coca Cola at a rate of 15ml Coke to 250 mL water, which is the high end of consumption for this study, 5ml to 250ml being the low end.

No doubt, but an occasional bolus of vinegar seems less harsh than what many people routinely consume.

Could even mitigate further with a straw

I didn't believe you, so I looked it up.

A PH of 2.37 for Coca Cola

A mean Ph of 3.10 for Taiwanese apple cider vinegar, and 2.78 for "Imported" apple cider vinegar. Somehow I can't believe what I'm reading but you appear to be correct and if anything are understating your case. Amazing what adding obscene amounts of sugar to a beverage will do to our perception of sourness. What you're saying is so counter-intuitive your post was grey by the time I got to it but unpopular doesn't mean wrong.

Honestly this mostly makes me worry about coca-cola though... maybe we should be diluting it and drinking it through a straw :)

Worth noting that ph is a logarithmic scale.

This means that apple vinegar is more acidic than you might think just by looking at ph if you don’t take that into account.

just for fun, try to convert 2.37 = log_10(x) & 2.78 = log_10(x), and see how large the difference is (A: 234.4 vs 602.6).
