I don't get the concept of diet soda. If you consume something unhealthy - shouldn't it at least taste good? Or is it some sort of self-punishment?

The unhealthy part is mostly the caffeine, not the aspartame, itself. That being said - I don't get the 'soda' at all. It's worse than plain water, juice (no extra sugars), espresso, and beer.

Stop drinking coke! It's not well for you. Especially when you get older. The problem lies within the phosphoric acid added in plenty amounts. It's not exactly only coca cola's problem, but it adds up. Phosphorus is been added everywhere - from Sausages (e.g. the one in hot dogs. Or, The one's intended to be grilled like the GERMAN SAUSAGE) to muffins. I think, it's called sometimes backing soda - the powder you add…

There is zero evidence for this. Put up some studies or shut up.

Same observation in Sweden. So I'm not going crazy! Not sure if our Pepsi is bottled in the same place, but our Coca Cola isn't.

Carlsberg Sverige and Ringnes AS (also Carlsberg), I'm guessing it's made locally. Haven't notice anything with the Swedish Pepsi max and I'm drinking _a lot_ of it. Didn't get the flu yet so my taste buds should be good! Coke zero got a lot better after the new recipe if you ask me but still a Pepsi guy :)

Might have been the new Coke Zero making the Pepsi feel worse in comparison, but I do feel like it goes flat faster than a few years ago.

It causes higher blood pressure and is statistically associated with heart problems. https://www.health.harvard.edu/staying-healthy/do-you-really...

I'm curious if that accounts for the effects of the caffeine in most diet sodas.

Or perhaps that overweight people like me are more likely to drink diet soda?

I once explained to a coworker that I brought in some soda that day because the diet soda at work was expired. They were skeptical and we proceeded to go down to the cafe to setup a blind taste test. I passed with flying colors and we had an interesting conversation about it. It was a fun 20 minutes of not working.

You weren't goofing off, you were applying the scientific method while at the same time engaging in team building. I'm not even kidding. That incidental silliness is valuable. A year later, you run across a problem where a customer explains a problem you don't understand, and then you have a flashback to that time when you did a blind taste test. You look at your colleague and whisper "Hey, remember that blind taste…

A bit of ridiculous goes a loooong way. Embrace the weird and fun.

Some time ago I could tell something was really off about the taste of my diet soda even though it was way before it's expiry date. I was able to find out some storage irregularities with the shop I was buying from and call CC on them. Turns out they were also doing a lot of stupid things like taking meat freezers out of socket overnight to reduce energy consumption.

What's CC? Health inspection?

CDC (Centers for Disease Control) maybe?

Some of us can't even drink the "good" tasting aspartame due to genetic factors. https://www.nature.com/articles/srep39135

I wonder what the genetic factor is for stevia, because oh boy does that taste awful. Aspartame is unpleasant, but stevia is something else entirely.

About the only diet sweeteners that taste sweet to me are xylitol and saccharin, and they're hard to find outside their niches (gum/mints and coffee sweetener). Kinda sucks tbh.

>Later, when he licked his fingers to turn a page, he discovered a very sweet taste. Since he realized that the compound he made was unlikely to be toxic, he tasted it and found it extremely sweet indeed. In fact, aspartame is about 200 times as sweet by weight as sugar. This is horrifying.

Explain?

Is the "jury still out" on Aspertame causing health problems like cancer?

There have been a number of studies linking artificial sweeteners to changes in gut biome (which can be a lot more serious than it sounds). Here is one recent example: https://www.sciencefocus.com/news/artificial-sweeteners-can-...

Intuitively, it would make sense that the introduction of such an artificial and alien chemical into the diet would have some kind of negative effect, for whatever that's worth. I say that as a fairly heavy user of sweeteners.
