Why Is Diet Soda Bad For You?

Exactly why is diet soda so bad for you and your health? It seems like a good thing, right? Less calories, less sugar, still satisfying.

Unfortunately, there is so more to this chemical cocktail than you may realize.

It Confuses You

Artificial sweeteners have more intense flavor than real sugar, so over time products like diet soda dull our senses to naturally sweet foods like fruit, says Brooke Alpert, RD, author of The Sugar Detox. Even more troubling, these sugar stand-ins have been shown to have the same effect on your body as sugar. “Artificial sweeteners trigger insulin, which sends your body into fat storage mode and leads to weight gain,” Alpert says.

It Leads To Weight Gain

Diet soda is calorie-free, but it won’t necessarily help you lose weight. Researchers from the University of Texas found that over the course of about a decade, diet soda drinkers had a 70% greater increase in waist circumference compared with non-drinkers. And get this: participants who slurped down two or more sodas a day experienced a 500% greater increase. The way artificial sweeteners confuse the body may play a part, but another reason might be psychological, says Minnesota-based dietitian Cassie Bjork. When you know you’re not consuming any liquid calories, it might be easier to justify that double cheeseburger or extra slice of pizza.

It’s Associated With Type 2 Diabetes

Drinking one diet soda a day was associated with a 36% increased risk of metabolic syndrome and diabetes in a University of Minnesota study. Metabolic syndrome describes a cluster of conditions (including high blood pressure, elevated glucose levels, raised cholesterol, and large waist circumference) that put people at high risk for heart disease, stroke, and diabetes, Bjork explains.

Diet Soda Can Destroy Your Teeth

Excessive soda drinking can significantly hurt your teeth, according to a case study published in the journal General Dentistry. The research compared the mouths of a cocaine-user, a methamphetamine-user, and a habitual diet-soda drinker, and found the same level of tooth erosion in each of them. Why? Citric acid, which weakens and destroys tooth enamel over time.

Diet Soda Has Been Linked To Depression

A recent study presented at a the American Academy of Neurology meeting found that over the course of 10 years, people who drank more than four cups or cans of soda a day were 30% more likely to develop depression than those who steered clear of sugary drinks. The correlation held true for both regular and diet drinks, but researchers were sure to note that the risk appeared to be greater for those who primarily drank diet sodas and fruit punches. Although this type of study can’t prove cause and effect, its findings are worth considering.

Soda Increases Heart Attack & Stroke Risks

Just one diet soft drink a day could boost your risk of having a vascular event such as stroke, heart attack, or vascular death, according to researchers from the University of Miami and Columbia University. Their study found that diet soda devotees were 43% more likely to have experienced a vascular event than those who drank none. Regular soda drinkers did not appear to have an increased risk of vascular events. Researchers say more studies need to be conducted before definitive conclusions can be made about diet soda’s effects on health.
