What's CC? Health inspection?

The local County Council perhaps? Seems they are the ones responsible for food safety in the UK.

But we don't say 'soda' (for the same usage). (And 'call CC on them' seems an unlikely phrasing to me, though you're correct that (a department of) the county council would probably be the port of call.)

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

I know lots of people claim that Coke Zero tastes "basically" the same as normal Coke, but to me it was literally the most disgusting soda I have ever tastes. Far worse than even Coke light for some reason.

>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?

What if it had been toxic?

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

Please link directly to the study ( https://link.springer.com/article/10.1007/s11606-011-1968-2 ) instead of just posting the PR announcement. I'll also note that this is part of the Northern Manhattan Study ( http://columbianomas.org/ ). I'll also note that it's not directly about aspartame but diet sodas in general (so if diet sodas has a consistently higher caffeine, then that could be the reason). I've also notic…

The carbonation is the difference. It will explode as it becomes a slush and make a massive mess.

That just happened to me. I left a 2 liter in the freezer. I then transferred it to the fridge, thinking the gradual temperature change would be fine. I woke to a strange sound. The bottle had blown the fridge door open, a large gash down the side of the bottle, soda slush everywhere. It took me an hour to clean the fridge.

> I woke to a strange sound.

Sounds like the time I woke to what sounded like a gun shot in my apartment. I had accidentally left a can of frozen orange juice concentrate on top of my fridge about a week prior. It had started to ferment, and eventually, bang. Like you, it took me ages to clean up that mess.

> If you unzip aspartame into the two amino acids and remove that methyl to become methanol, you have a tasteless mixture of pretty harmless compounds. I'm somewhat surprised nobody has commented on this yet, so let me point it out: methanol is not harmless! It causes blindness or death. (I don't say diet soda is harmful, only that methanol is.)

I'm somewhat amused that pointing out that methanol is actually deadly even if this isn't a problem in diet soda has cost me two downvotes : ) (No, I'm not complaining. I can't cash out HN karma points in Norwegian banks so to me it is just a bit puzzling because I wonder what triggered those, somewhat amusing and mildly scary.)

Never saw the point of diet sodas. I'd much rather drink normal coke with proper sugar in it. It's unhealthy, yes - so drink slightly less.

I switched from drinking exclusively sugar soda to exclusively sugar-free soda, and very quickly ended up preferring the taste of the latter. But I also discovered that non-sugar sweeteners feel a lot… lighter? They're easier to drink, simply put; my body knows it's not sugar somehow. I also have discovered I don't like the sugar rush, feeling on the teeth or aftertaste of a sugary soda.

I have also noticed significant reduction in carbonation of Coke and Pepsi. 2-3 years ago it would hit the spot so to speak. Now they taste flat as if they have been sitting out all day. Wild thought was they are doing this to reduce “co2” emissions :)

No. Aspartame is one of the most studied and tested substances on the planet and they still haven't linked a single problem to it. At least not one that doesn't relate to sweeteners in general. Nothing else has gone under so much scrutiny (Maybe MSG). Seems like a too good to be true situation where people can't accept its actually this good.

Speaking of people being afraid of MSG, As far as I'm concerned that's racist. The only reason people are afraid of seaweed extract (MSG) is because some racists person made up "Chinese Food Syndrome". People repeating the lie are affectively passing on something based on racist propaganda. It's also the reason much of the asian food in the bay area doesn't taste nearly as delicious as the real deal in asia. Because…

> The only reason people are afraid of seaweed extract (MSG) is because some racists person made up "Chinese Food Syndrome".

Not exactly. I agree the term is racist, and that racist sentiment may way spur disinformation on MSG. But the fear actually began in 1968, during the beginnings of the modern 'health food' movement, with a letter written in the New England Journal of Medicine by a man named Robert Ho Man Kwok describing his supposed symptoms from eating MSG. The body of follow up research showing no such effects is much less interesting to people than the scary story that started it all.
