Is drinking too much Coca-Cola bad for you?

I know someone who has been drinking nothing but mineral water for years on end. He struggles with high blood pressure and tends to over-salt everything he eats.
I'm wondering if drinking this much Coca-Cola could lead to issues like kidney stones, liver problems, or something similar. I'm not sure how much mineral water is actually safe to consume—especially since it's carbonated, right?

thanks.

His main issue is really just the salt content in his food—though if he starts showing signs of a critical state, then we’re looking at a water problem too! As for the water itself, pretty much everything is mineralized unless you're talking about distilled stuff. It really just comes down to the specific composition. I mean, basically, sodium is dissolved in all surface water that picks up minerals as it flows along its path. Simple as that!

There’s just way too much hype going around lately regarding carbon dioxide, and honestly, people are trashing sparkling drinks without any actual logic behind it! It's getting ridiculous. Carbon dioxide in sodas—besides giving them that signature kick—actually keeps the drink fresher for longer. And yeah, that goes for sparkling water, too. You look at those "all-natural" juices and they’re usually packed with way more preservatives just to stay shelf-stable. It's most obvious in the thicker, denser juices because they have so much more solid matter in them, so they absolutely need more preservatives to keep from spoiling. It's just basic science!

Carbon dioxide in water pulls the pH levels toward the acidic side—which can be a real pain for your teeth—and it pumps extra gas into your stomach, but honestly, it’s not like the stuff is inherently bad for you or anything! It just is what it is.

Oh, wait! I totally blanked on the whole kidney stone thing. You know, you can actually develop those even if you’ve never touched a single drop of sparkling water or anything heavily mineralized in your life. On the flip side, there are people who chug carbonated mineral water from sunrise to sunset and never deal with a single stone—it’s honestly just a huge part of your genetics. Of course, if your body is already naturally predisposed to carbonate-based stones, then sipping on bubbly mineral water is definitely going to speed up the process. But hey, magnesium actually helps break that stuff down! And if you're looking for a serious magnesium boost, Gerolsteiner is loaded with it. It really does help!
