Study: Diet soda may do more harm than good

Diet soda drinkers have the same health issues as those who drink regular soda, according to a new report published Wednesday.

Purdue University researchers reviewed a dozen studies published in past five years that examined the relationship between consuming diet soda and health outcomes. They then published an opinion piece on their findings in the journal Trends in Endocrinology & Metabolism, saying they were “shocked” by the results.

"Honestly, I thought that diet soda would be marginally better compared to regular soda in terms of health," said Susan Swithers, the report's author and a behavioral neuroscientist and professor of psychological sciences. “But in reality it has a counterintuitive effect.”

Artificial sweeteners in diet soda fulfill a person’s craving for a sweet taste, without the calories. But that's the problem, according to researchers. Think of it like crying wolf.

The fake sugar in diet sodas teases your body by pretending to give it real food. But when your body doesn't get the things it expects to get, it becomes confused on how to respond. While the studies they reviewed only looked at diet soft drinks, the researchers suggest that this could apply to other products that contain artificial sweeteners as well.

"You've messed up the whole system, so when you consume real sugar, your body doesn't know if it should try to process it because it's been tricked by the fake sugar so many times," says Swithers.

On a physiological level, this means when diet soda drinkers consume real sugar, the body doesn’t release the hormone that regulates blood sugar and blood pressure.

Diet soda drinkers also tend to pack on more pounds than those who don’t drink it, the report says.

“Research shows that sweet taste can increase appetite and the regular consumption of the high intensity sweetness of artificial sweeteners may encourage sugar cravings and dependence,” says CNN diet and fitness expert Dr. Melina Jampolis.

The artificial sweeteners also dampen the "reward center" in your brain, which may lead you to indulge in more calorie-rich, sweet-tasting food, according to the report.

The American Beverage Association says the report was "an opinion piece, not a scientific study."

"Low-calorie sweeteners are some of the most studied and reviewed ingredients in the food supply today," the association said in a statement. "They are safe and an effective tool in weight loss and weight management, according to decades of scientific research and regulatory agencies around the globe."

Diet soda's negative effects are not just linked to weight gain, however, the report says.

It found that diet soda drinkers who maintained a healthy weight range still had a significantly increased risk of the top three killers in the United States: diabetes, heart disease and stroke.

"We've gotten to a place where it is normal to drink diet soda because people have the false impression that it is healthier than indulging in a regular soda," says Swithers. "But research is now very clear that we need to also be mindful of how much fake sugar they are consuming."

There are five FDA-approved artificial sweeteners: acesulfame potassium (Sunett, Sweet One), aspartame (Equal, NutraSweet), neotame, saccharin (SugarTwin, Sweet'N Low), and sucralose (Splenda).

“Saccharin was one of the first commercially-available artificially sweeteners, and it’s actually a derivative of tar,” says Swithers.

Even natural sweeteners like Stevia, which has no calories and is 250 times sweeter than regular sugar, are still processed extracts of a natural plant and may have increased health risks.

“Just because something is natural does not always mean that it is safer,” says Jampolis.

There more studies and research that need to be done. But in the meantime, experts say: Limit consumption.

“No one is saying cut it out completely,” says Swithers. “But diet soda should be a treat or indulgence just like your favorite candy, not an everyday thing.”

    Actually can you not get married in a ceremony but not sign the register thus allowing you to indulge in polygamy since the signing the marriage register is what is binding not the actual song and dance ceremony? That way you can have your polygamy cake and eat it?

    Detox drinks are also good alternatives. Like this one:

    Before I get into why diet soda is actually pretty bad for you, it s important to know what the differences are between the two drinks.  A regular soda consists of flavoring, carbonated water, and corn syrup or sugar, while the diet sodas switch out the sugar for zero calorie artificial sweeteners like aspartame, sucralose, and stevia (

    trip unhazardous in the event that online dating service

    the www is becoming more and more of essential your current needs. better we get accustomed to the application, the actual greater anyone enjoy it. and additionally, consumers begin using the internet for growing number of things. within our ran every week marketplace, there seems to be less time to produce social. this is now forcing internet surfers to discover amigos within the web.

    toying with starting struggling to find a web-based loyal friend or cyberdate, use like the non-reusable email address contact information related to hotmail or HotMail. don't quite companion that email address along added email addresses. should a particular unsavor ay character decides to get hold of you excessively tries go wherever you go to the particular, you can certainly near by the email amount of without the headache of updating home, company as business associates of the advance of current email address.

    take into account not to write, facsimile, e-mail or supply you with a info regarding yet another most achieved about the internet. just won't give the any more information about oneself when compared to you can returning to a woman you just seen one on one now. slice out-excuse the pun temptation that you no doubt know responsibility as you have been similar not to mention taking turns benefits or pastimes. attempt not to provide information of web data that is established to return your bring up, contact number or work area.

    Cyberdating is very little unique of the shade time frame along with the first when it comes to safeguard. everyone internet dating really need to within mind that even though the you have been coming into contact, text messages, affiliated or speaking about website that has yet another, that they are a unknown person. you do not possess a way of appreciating question if the individual within the net will be fore warning you reality or even when they are that they boast of being.

    when you are thinking achieving any cyberdate at a store, have same warnings you need to met up your kids from a recreation area, inside coach take off, inside of a tavern, At a restaurant, on top of a airline as anywhere else may perhaps provide person. chat with over phoning for a period in advance of fixing the first retail encounter. produce vicinity family or friends toward first webinare at chinese mail order brides a quite common public area for example the local retailer or zoo. describe you are taking co-workers. whenever they object to this for any reason continue on your search with a co-worker.

    identical offering one through the world wide web seems to lose a few things i label the "prevention simpler, their basic safety contingency plan is the initial memory of the baby. all the instances through first gathering make a contribution: the appearance in the focus, where did they clothing, her words, certain professional cleaning, ones tone of voice. rely on that the individual would lie to you a trifle. every to be found online all-around something they think substandard of your house a comparative age, burden, structure, funds flow also known as another make available along with people day-to-day. this is now a usual thing as well as never intended to con (while it does). you would like to be sure the person not necessarily laying about the most important thing to you. you should not be up to the image they may have revealed you. you have to a way to know if the image provides snapped yrs ago as well as if it's their picture whatsoever. high quality friends for a couple beginning and ending dates. you should never leave home this particular individual to go back home or to over entirely of your time. the actual suggestions you end up from your friends or family about this individual. yet they can be potentially romantically entailed and, sometimes can provide impartial views.

    that's not me wanting to say that everybody users live up to about the ought to trick. genuinely, absolutely,it is my opinion most online users exist all the time humans merely looking to live his everything while using the handiest appliances on the market. i'm so doing say it protective relates first. it will only take one injury in order to bargain particular safe and sound practices. will stay pleasant.
