May 5, 2017 -- around one in five Americans drinks diet soda every day, follow to the CDC. Is the a good thing?

Numerous research studies over the previous several years have actually reported links between diet soda and weight gain, diabetes, heart problems, and other wellness issues. Most recently, headlines sounded alarms about a greater chance the dementia and also stroke among diet soda drinkers .

You are watching: Is diet soda good for you

That might sound worrisome, but experts say you don’t need to clear the diet drinks out of her fridge simply yet. Numerous questions need to be answered prior to we’ll recognize whether diet soda raises your possibility of health and wellness problems.

Diet Soda, Dementia and Stroke

Boston university researcher Matthew Pase, PhD, and also colleagues examined 10 year of wellness information from virtually 3,000 American adults over 45 to count the number who had actually a stroke. They go the very same for virtually 1,500 American adult over 60 to determine exactly how many occurred dementia.

After accounting for a selection of things that can influence their health, such as age, physical activity, and also waist size, the researchers found that diet soda drinkers practically tripled your odds of stroke and also dementia, contrasted with those who drank no diet soda.

Scary, right? not necessarily, states Pase. Only 81, or 5%, that the human being in the research were diagnosed through dementia, and only 97, or 3%, had actually a stroke.

“At the finish of the day, we’re talk about tiny numbers the people,” claims Pase. “I nothing think that people should it is in alarmed.”

Pase also makes clear that his study’s results, released in April in the journal Stroke, don’t explain the link. Carry out diet sodas reason health problems like stroke and dementia? Or do civilization who have higher chances of getting such health problems pick to drink diet soda, possibly to try to reduced sugar and also calories in their diets? Pase can’t say.

Links, but No Cause and also Effect

Other research studies have additionally tied health concerns to diet soda extensively rather than to specific artificial sweeteners. (The FDA has approved 6 for usage in drinks and food.) like Pase’s study, they could not show whether diet soft drinks were to blame.

A 2015 BMJ review of studies likewise found that a solitary daily serving of diet soda increased the opportunity of diabetes through 8%.

The authors of these research studies suggest plenty of explanations because that the links in between diet soda and also health concerns. In addition to potentially transforming gut bacteria, fabricated sweeteners might stimulate the appetite, which could lead to overeating. Researchers don’t know yet whether this explanations will prove to be accurate.


David Ludwig, MD, PhD, says that studies favor these raise crucial concerns about diet soft drinks, however they"re no proof the we need to be worried.

“We need much more clinical trials,” claims Ludwig, an endocrinologist and also professor of nutrition at the Harvard T.H. Chan school of public Health, and also author the Always Hungry.

Ludwig carried out a check in 2012. In it, he randomly separated 224 overweight or obese teens right into two groups. One group continued their common habit of drink sugary sodas; the other group switched come diet sodas. ~ a year, the diet soda group had reduce a little bit of weight, contrasted with those that drank consistent sodas. By the 2-year mark, however, the two groups were around the same.

In an additional clinical trial, participants that drank diet soda lost around 5 pounds more than water drinkers over a 12-week period. However, that study was funded by the American Beverage Association, a trade group that represents soda makers.

Overall, says Ludwig, clinical trials have displayed that if you switch from sugary sodas to diet ones, her weight will certainly benefit. However, no clinical trial has yet been long enough to answer whether diet sodas affect the odds of having actually diabetes or whether they are as safe together unsweetened drinks favor water. Diabetes and obesity, Ludwig says, space the primary focus of concerns around diet soda.

“Compared come unsweetened beverages,” asks Ludwig, “are they causing harm?”

Why your Diet Soda may Derail her Diet

One feasible explanation because that the link between diet sodas and also weight gain and diabetes risk: The sweeteners in diet soft drinks might trick you right into overcompensating, or eat a higher number calories than you normally would, says Christopher Gardner, PhD, manager of nutrition studies at the Stanford avoidance Research Center. This can happen in among two ways.


The first, the says, is psychological. If you pick a no-calorie diet soda end a continuous soda, you may reward yourself later on in the day with a treat. And also that treat might have an ext calories than you saved by avoiding the sugary soft drink.

Your mind chemistry might play a role as well. The sweet in the diet soda might prime your brain to suppose a calorie boost. When no calories space on the way, that could create your appetite and lead you to eat more.

“Diet sodas may aid you with weight ns if you don’t overcompensate, yet that’s a big if,” states Gardner, who"s likewise a professor of medication at Stanford University.

Ludwig suggests that drink artificially sweetened beverages may affect your taste buds in ways that make you much less likely to select healthy foods.

“You may find fruit much less appealing since it’s much less sweet 보다 your soda, and also vegetables may come to be inedible,” he speculates.

Both Gardner and also Ludwig identify that your theories are just that: Theories.

To Drink or no to Drink Diet Sodas

The American Beverage Association claimed in a statement the the FDA and other health and wellness organizations consider artificial sweeteners safe, and also no research has presented otherwise .

“Scientific evidence does display us the beverages containing these sweeteners deserve to be a advantageous tool as part of an as whole weight management plan. America’s beverage companies support and encourage balanced lifestyles by providing civilization with a variety of beverage choices -- with and also without calories and sugar -- for this reason they can choose the beverage that is appropriate for them.”

Seattle-based dietitian angel Planells encourages civilization to pick water end soda of any type of kind. But, the says, diet soda have the right to fit right into your diet as long as you do other healthy food choices.

“If girlfriend drink a diet soda, that won’t make up for eating a super-size rapid food meal,” says Planells, a spokesman for the Academy of Nutrition and Dietetics.

Breaking the diet soda habit, if you pick to do so, deserve to be tough, says Planells. The recommends beginning with baby steps rather than going cold turkey. If you drink 5 or six diet sodas a day, drop down to two, come three, and also then to one. Just be certain to drink water so you remain hydrated.


Ludwig advises civilization who want to obtain off sugary drinks to consider diet soda a momentary choice.

“I phone call my patient to proceed making the change to unsweetened beverages,” that says. “We know that diet sodas are much better than sugary beverages in regards to body weight, however we don’t understand if much better is in reality good.”
