While the data indicates a potential connection between diet soda and health hazards, it doesn’t clearly establish a direct cause-and-effect relationship linking sweeteners to conditions like stroke or dementia. Experts have promptly reiterated the principle that “correlation does not imply causation” and urged caution in interpreting these findings. They pointed out various shortcomings, including the researchers’ acknowledgment that when factors such as diabetes, genetics, and obesity are considered, the link to dementia fades away. Moreover, no correlation was found between sugary drink consumption and stroke risk, despite this being a well-accepted association. It’s plausible that individuals already facing health issues, particularly those with diabetes, may be more inclined to opt for zero-calorie beverages, which could distort these results.
In the meantime, many specialists recommend that all carbonated drinks, regardless of their sweetening method, be consumed in moderation. Research into the health risks associated with soda has been ongoing, with some studies suggesting a connection to weight gain. In light of this recent research, the American Beverage Association issued a statement noting that global organizations such as the U.S. Food and Drug Administration, the World Health Organization, and the European Food Safety Authority have consistently reviewed the safety of artificial sweeteners and concluded they are safe.
Regardless of whether artificially sweetened drinks pose a health risk, consumers are increasingly seeking alternatives, including naturally sweetened low-calorie beverages and bottled water. Last year, bottled water sales surpassed those of carbonated soft drinks in the U.S., making it the largest beverage category by volume. National soda sales have been declining as consumers turn away from sugary drinks in favor of healthier options. For example, a tax on sugary drinks in Berkeley resulted in a 21% decrease in sales, while in Philadelphia, PepsiCo announced plans to lay off 80 to 100 employees after sales plummeted 40% due to the city’s tax.
Although recent studies are unlikely to significantly impact soda sales in the short term without more conclusive evidence linking these beverages to dementia and stroke, the ongoing challenges facing the beverage industry certainly do not present positive news. Additionally, discussions around calcium carbonate versus calcium citrate have emerged, with some consumers showing interest in alternatives that may offer better health benefits, further influencing their choices in beverage consumption.
