Your Diet Soda Habit Is Messing With Your Heart


Frida Marklund

If you still think Diet Coke is the lesser of two evils, it's time to reconsider. It turns out that even sugar-free sodas can have a serious impact on your heart health—and in minimal serving sizes, to boot.

A new study published in the medical journal Heart shows that those who consume just two cans of soda per day—regularly or artificially sweetened—are about 23% more likely to develop heart disease. Of the 42,000 participants in the study, which was based on survey answers, there were more than 4000 reported heart failure incidents and 509 deaths.

It's worth noting that the study participants were all male, and men are more at risk for heart failure than women in general. But given that we've always assumed diet soda is the healthier option (even if it's not actually healthy), the lack of differentiation between the two and their connection to heart issues is kind of mind-blowing. Our advice? Cut down to one can a day, and instead opt for Zevia ($30 for 24), which is naturally sweetened with stevia (a calorie-free and low-glycemic plant), sans chemicals. (It tastes the same—promise.)
