Artificial sweetners may contribute to obesity & diabetes.

Artificial sweeteners are widely accepted as safe for those who tolerate them well but there were some interesting articles this week suggesting they might actually be contributing to the rise of obesity and type 2 diabetes by inducing metabolic changes via our gut bacteria. The artificial sweeteners used in they study were aspartame, sucralose (Splenda) and saccharine. The largest effect was found with saccharine.
"The artificial sweeteners that are widely seen as a way to combat obesity and diabetes could, in part, be contributing to the global epidemic of these conditions.
Sugar substitutes such as saccharin might aggravate these metabolic disorders by acting on bacteria in the human gut, according to a study published by Nature this week (J. Suez et al. Nature http://dx.doi.org/10.1038/nature13793; 2014). Smaller studies have previously purported to show an association between the use of artificial sweeteners and the occurrence of metabolic disorders. This is the first work to suggest that sweeteners might be exacerbating metabolic disease, and that this might happen through the gut microbiome, the diverse community of bacteria in the human intestines. “It’s counter-intuitive — no one expected it because it never occurred to them to look,” says Martin Blaser, a microbiologist at New York University.

Can't say anything about the diabetes one. But the obesity one seems suspect. Unfortunately it doesn't link to the actual research paper in the article. But a two obvious questions that spring to mind would be:
How much were the mice fed of the artificial sweeteners in relation to their weight? I remember another study in the aspartame thread that literally stuffed mice with so much aspartame that you'd need to drink a few gallons of diet soda every day to get the same amount in relation to your body weight.
How does changing your gut flora impact weight loss/gain at the same amount of calories eaten? Does it increase the amount of calories extracted from food? Decrease your energy output? There's no other way it could do anything about your weight.0 -
It doesn't. Just more hogwash. Calories in/calories out. period.How does changing your gut flora impact weight loss/gain at the same amount of calories eaten?

The full article and methodology are behind a paywall but this does make it sound like outrageous dosages weren't used.
"This dose corresponds to the FDA acceptable daily intake (ADI) in humans (5 mg per kg (body weight), adjusted to mouse weights, see Methods)." http://www.nature.com/nature/journal/vaop/ncurrent/full/nature13793.html

There was an article in (the unreputable) Daily Mail too on this recently. I did not bother to post on it as, well, regardless of who gave input to the article (including a dietitian at a top London hospital), it is a tabloid paper.
But here is the link to that one, for anyone interested.
There are a few in this article refuting the findings too.

Yes let's blame something other than our own self control!0

The research has been on small scale and lots done with mice. I'll reserve my diet Pepsi (which I've been drinking for more than 25 years) till they come up with evidence that's much more convincing.
Artificial sweeteners have been one of the most studied additives since they've been added to the food chain. With the exception of some "natural" sites trying to dissuade the public from using them, there's little (if any) evidence to show they are harmful IF taken in moderate doses.

I saw the article in the NY Times and there's a lot of if and maybe about it. I have 1 diet soda a day and that's it. I also eat yogurt and take probiotics. Not too worried.0

Of course everyone is responsible for their own personal weight but that doesn't negate the potential benefit of conducting scientific studies -- especially given the dramatic increase in obesity and diabetes in such a short period of time. I know put-down-the-chips-and-get-your-lazy-*kitten*-off-the-couch is a satisfying answer but perhaps there's more to it? Nothing wrong with keeping an open mind and seeing where the research leads.Yes let's blame something other than our own self control!0 -
I've got a theory I know it may be a bit out there and may not be a normal theory but go with me with me on this this 'Eating too much food can lead to Obesity' yes I know that's a pretty wild concept but you never know that could be the cause ..........0

Science is a good thing to pursue. We all thought ulcers were caused by stress until fairly recently. Turns out it was a bacteria in most cases. Just because something can be shown to CONTRIBUTE to obesity STILL doesn't negate responsibility - but there's no reason to make it harder.
Besides, artificial sweeteners are so low calorie that it's negligible. Many people drink diet sodas and consume low calorie sweeteners because they're trying to follow a lower calorie intake - so if the very things that are supposed to HELP them lose weight actually really AREN'T, then maybe it should be made known. But I guess telling people to put down the fork and never do any further investigation is the way to go.0 -
I am so glad I am not a mouse....0

This. Science is our friend.0 -
Artificial sweeteners being so controversial are one of the most studied additives on the planet, there is absolutely zero conclusive evidence to back up any of these claims. I dropped 115 lbs, and have substantially recomped my body, and I use the hell out of artificial sweeteners. Would you like to buy some magic beans? They are magic fat burners that I got from Dr. Oz.0

The subjects in this study were given the maximum dosage of artificial sweeteners recommended on a daily basis. And the study also says much more research is needed before there's anything concrete.
I have 4 sweet n low packets a day, max. Don't plan on stopping. I'm obese due to my eating habits, not because I like my tea with a bit of artificial sweeteners.

I am my own human guinea pig and I can testify to the fact that artificial sweeteners do not cause weight gain or diabetes. In fact, pretty much daily ingestion of artificial sweeteners in my case has put my a1c numbers in the healthy range for pretty much the entire year at this point, and I have lost 83 pounds.
So screw those mice.0 -

This…so much this…
You know what made me fat? You know what made my mother fat and pre-diabetic. Eating too much food. It has NOTHING to do with artificial sweeteners.
I could eat 5,000 calories of nothing but vegetables or 5,000 calories of stuff with artificial sweeteners and either way, I'm gaining weight.0 -
I'd be curious how often saccharin is used currently.0

I saw a 30 year old bottle in my Granny's cupboard if you want some.I'd be curious how often saccharin is used currently.

This is pretty much what I was getting at although I phrased in that way in case it's still widely used and I'm just not aware of it.0 -
It was recently unbanned in Canada. My folks used to bring it back from the US because it was the only sub they liked and it was banned here for years. Somehow, that just made it taste sweeter

Cool anecdote:
All my overweight saccharine swilling grandparents lived to over 100 years old. Maybe if they`d stayed off the saccharine they`d still be with us. My folks are in their late 80s and going strong. It`s probably the gardening, and maybe just possibly, their genes.0 -
I think as long as you are not a mouse, then you are safe from artificial sweeteners.
Besides, I always thought rats were the preferred rodent testing medium anyway. What's with the mice?0 -
Or they may not. Funny how that works.0

Last time I had it was in a TAB when my grandmother was still alive and drinking it. She died of heart failure at 84 BTW.I'd be curious how often saccharin is used currently.

For anyone who's still interested here's a link to a pdf of the research article published in Nature from Mark's Daily Apple:
Artificial sweeteners induce glucose intolerance by altering the gut microbiota
http://cdn.marksdailyapple.com/wordpress/wp-content/uploads/2014/09/Artificial-sweeteners-induce-glucose-intolerance-by-altering-the-gut-microbiota.pdf
And Mark Sisson's blog post:
Artificial Sweeteners May Leave You Absolutely Gutted
http://www.marksdailyapple.com/artificial-sweeteners-may-leave-you-absolutely-gutted/
And Slate's article:
"We may soon find out what, exactly, non-caloric sweeteners are doing to our microbiomes, and whether it affects our health. But for the time being, the conventional wisdom remains the same: To the extent that artificial sweeteners help us wean off sugared drinks, they’re a boon to public health."

Saw a cousin's beard fall out from morbidly-extensive use of aspartame, pretty sure that'll keep me off the stuff way better than some iffy study about gut bacteria issues, which are practically a red herring considering our society's far bigger problems regarding caloric intake and macronutrient ratios.0
