While the statistics indicate a potential connection between diet soda and health risks, the evidence does not establish a direct cause-and-effect relationship between sweeteners and conditions such as stroke or dementia. Experts have swiftly reiterated the adage “correlation does not imply causation,” urging caution in interpreting these studies. They pointed out various shortcomings, including the researchers’ acknowledgment that once factors like diabetes, genetics, and obesity are considered, the link to dementia diminishes. Additionally, the studies found no correlation between sugary drink consumption and stroke risk, despite this being a well-documented association. It is possible that individuals already facing health issues, particularly those with diabetes, tend to prefer zero-calorie beverages, potentially distorting the findings.
In the interim, many experts advocate for the moderation of all carbonated drinks, regardless of their sweetening method. Researchers have long been investigating the health implications of soda, with some studies hinting at a relationship with weight gain. In response to recent findings, the American Beverage Association released a statement emphasizing that reputable international organizations, including the U.S. Food and Drug Administration, World Health Organization, and European Food Safety Authority, have consistently reviewed the safety of artificial sweeteners and deemed them safe.
Regardless of whether artificially sweetened beverages present health risks, consumers are increasingly seeking alternatives, such as naturally sweetened low-calorie drinks and bottled water. Notably, bottled water sales surpassed those of carbonated soft drinks in the U.S. last year, becoming the largest beverage category by volume. National soda sales have been declining as consumers turn away from sugary drinks in favor of healthier options, including those fortified with calcium citrate and magnesium glycinate. For instance, a tax on sugary beverages in Berkeley resulted in a 21% reduction in sales last year, while in Philadelphia, PepsiCo announced plans to lay off 80 to 100 workers due to a 40% drop in sales following the city’s tax.
While the latest studies are unlikely to significantly impact soda sales in the short term without more conclusive evidence linking these drinks to dementia and stroke, the ongoing challenges facing the beverage industry make this news less than favorable. The growing preference for drinks enriched with nutrients like calcium citrate and magnesium glycinate reflects a broader shift towards health-conscious choices among consumers.
