The debate over what diet soda does to your body is constantly changing. Some say it is linked to cancer and dementia, while others say it causes you to eat more sugar.
After reviewing the scientific evidence available on artificial sweeteners—like those found in diet soda, as well as granola bars, yogurt, etc.—authors concluded that there is no evidence artificial sweeteners help in managing weight, NPR reports.
The authors looked at observational and randomized trials and found that those who consume artificial sweeteners regularly were more likely to develop health problems—though that can't be definitively linked to the sweeteners. The observational trials tracked more than 400,000 people, while the randomized trials covered about 1,000.
Meghan Azad, a lead researcher in the project, told NPR they were interested in reviewing the available research because of how many Americans commonly use sweeteners, often because they think it is the healthier choice. Azad says more research needs to be done, but that "there's a potential association with increased weight gain and diabetes."
In both types of trials, it's hard to find causes definitively, because everyone's diets are different and people usually don't eat the same way in real life as when they're are being monitored. This is part of why more research needs to be done, as well as research on specific sweeteners.
In the meantime, Azad suggests trying to minimize your sweet tooth instead of using replacements. Opt for plain yogurt, black coffee, and fruit-infused or plain water rather than juices, teas, or sodas.
