'''Diet soda''' is sugar-free or sugar-reduced soda marketed to those that want to reduce [[sugar]] intake in soda, but find [[water]] too nasty and boring. To make diet soda taste sweet, even if they have minuscule sugar, companies rely on artificial [[sweetener]]s (such as [[aspartame]], saccharin, and sucralose) or naturally-derived stevia. These sweeteners are many, many times sweeter than sugar, but they don't ever taste quite as good. These sweeteners, since they are not sugars, are often the source of problems people have with diet soda.

There are many types of diet soda but they all seem to taste the same. The black cans of Coke Zero and Pepsi Zero have been marketed as something that tastes like the original drink, better than the silver ones, and there are drinkers that swear that Coke Zero tastes better, but it doesn't appear that people know the difference between the contents of the silver can and black can.<ref> ''[[Huffington Post]]''.

==Aspartame==

Despite being very well studied, being used for 30 years, being deemed safe for consumption (except for people with the [[genetic]] disorder phenylketonuria) by more than 90 regulatory agencies around the world, and showing no evidence of risks in humans despite decades of usage,<ref name="pepsi">Novella, S.

It's gotten so bad that Pepsi caved to public pressure and removed the ingredient.<ref name="pepsi"/>

==Backfire effect==
There has been another circulated claim that drinking diet soda tricks the [[brain]] and deprives one of sugar despite drinking something sweet, so the body makes up for it by intensifying sugar cravings. Therefore according to the claim, people end up eating more sweet foods than if they just drank regular soda. This has been derived from a few studies that found a mere correlation between obese people and consuming diet drinks.<ref>''Bon Secours''. (January 19, 2014).[https://www.bonsecourssurgicalweightloss.com/2014/01/drinking-diet-soda-to-lose-weight-may-backfire-study-warns/ Drinking Diet Soda To Lose Weight May Backfire, Study Warns].

In the absence of any obvious mechanism, it is hypothesised that the apparent correlation between diet soda and diabetic or pre-diabetic conditions is due to "residual confounding by other dietary behaviors, lifestyle factors, or demographic characteristics", i.e. it's not diet soda that is responsible but other factors that the study did not control for.<ref>[https://care.diabetesjournals.org/content/32/4/688 Diet Soda Intake and Risk of Incident Metabolic Syndrome and Type 2 Diabetes in the Multi-Ethnic Study of Atherosclerosis (MESA)], Jennifer A. Nettleton et al, Diabetes Care 2009 Apr; 32(4): 688-694. https://doi.org/10.2337/dc08-1799</ref> Consuming diet soda to try to cut down sugar is a viable part of the effort to avoid the negative health consequences of too much sugar, and research shows that people who drink diet sodas as part of a calorie-controlled diet lose weight.<ref>[https://www.webmd.com/diet/features/diet-sodas-and-weight-gain-not-so-fast#1 Diet Sodas Cause Weight Gain? Not so Fast], WebMD</ref> Of course, correlation != causation and perhaps these studies don't show that diet sodas help you lose weight, but they do suggest that they don't make it harder.

A similar, but somewhat more plausible, "backfire effect" mechanism hypothesis states that drinking diet soda tricks your brain into thinking you've consumed sugar, and so your endocrine system readies itself for the supposed incoming sugar assault by producing insulin. Since no sugar is actually forthcoming, your cells have to ignore this extra insulin, which reduces insulin sensitivity over time and eventually gives you Type 2 diabetes. Studies of this hypothesis show mixed results.<ref>''Healthline'', [https://www.healthline.com/nutrition/artificial-sweeteners-blood-sugar-insulin#section4 How Artificial Sweeteners Affect Blood Sugar and Insulin]</ref>

==Better than water?==
It is claimed by the diet soda industry that consuming diet soda is better than drinking [[water]] at promoting weight loss, with a 2014 University of Colorado study apparently showing this. However the study, which was funded by the diet soda industry, has been criticised: it failed to adequately control for all relevant factors, and the study forced people who normally drink diet soda to give up diet soda and drink water as well as pursuing other weight loss techniques, while the group which kept drinking diet soda in contrast had an easier time. Willpower is generally considered a finite resource, and it's really hard to give up lots of things at once; an experiment which forced people who don't drink diet soda to quit drinking regular-sugar Coke might have given a different result.<ref>[https://edition.cnn.com/2014/05/27/health/diet-soda-weight-loss/index.html Diet soda helps weight loss, industry-funded study finds], [[CNN]], May 27, 2014</ref><ref>[https://www.foxnews.com/health/dispelling-3-diet-soda-myths Dispelling 3 diet soda myths], [[Fox News]], October 27, 2015</ref>

==Other additives==
Certain soft drinks have additives which may not be suitable for [[vegan]]s, [[vegetarian]]s, or those with religious prohibitions against eating pork or beef. This is true of both sugar and low-sugar drinks, but has led to a lot of rumor and misinformation. Most contain no animal products, but some sodas colored with beta-carotene contain fish gelatine as a stabilizer: this includes Lilt and Lilt Zero in the UK.<ref name=cokevegan>[https://www.coca-cola.ie/faq/coca-cola-drinks-suitable-for-vegans-and-vegetarians Are all the drinks sold by Coca-Cola IE suitable for vegans and vegetarians?], Coca Cola UK, accessed 9 Dec 2019</ref> More suspiciously, Diet Pepsi is not suitable for vegans but its makers refuse to say what is the non-vegan ingredient.<ref>[https://www.birminghammail.co.uk/news/midlands-news/diet-pepsi-vegan-drink-cola-12711475 Can vegans drink Diet Pepsi?

==Diet soda and Mentos==
{{wpl|Diet Coke and Mentos eruption}} is a cool and well-known phenomenon, and it works best with diet drinks because there's a pretty creamy brown color and you don't have to worry about the sugary residue that's left behind. No, this combination does not kill children.<ref>Mikkelson, D. (November 9, 2006). [https://www.snopes.com/fact-check/non-compos-mentos/ Mentos and Coke Death]. ''Snopes''. Retrieved August 25, 2019.</ref> It is very ill-advised to ingest the two yourself, however. If you do, your mouth will be forced open and gas and frothing soda will spill out of your mouth, and there's a lot of physical discomfort involved.

There are also rumors about mixing Diet Coke with other things causing an explosion, including ham. Snopes rejected claims about ham.<ref>[https://www.snopes.com/fact-check/spiral-sliced-blam/ Ham in Diet Coke Explodes?], Snopes.com</ref>

==Other myths==
* ''Diet sodas cause strokes or dementia'': as with other claims of bad effects, this has been shown by the occasional study, based on correlation but there's no obvious mechanism or evidence of causation.<ref>[https://www.snopes.com/fact-check/one-diet-drink-risks/ Can Drinking One Diet Drink a Day Triple the Risk of Dementia and Strokes?], Snopes.com, 31 Oct 2018</ref>
* ''One-calorie drinks contain more calories than they claim'': Snopes investigated the claim "Diet Coke (or Diet Pepsi) contains more calories than claimed, but the company gets away with the deception by paying a yearly fine" and unsurprisingly found it false.<ref>[https://www.snopes.com/fact-check/diet-riot/ 1 Calorie Diet Sodas Rumor], Snopes.com, 26 Aug 2013</ref>
