While statistics indicate a potential connection between diet soda and health risks, they do not establish a direct cause-and-effect relationship between artificial sweeteners and conditions such as stroke or dementia. Experts are quick to reiterate the age-old adage that “correlation does not imply causation,” urging caution in interpreting these findings. They pointed out various shortcomings in the studies, noting that the researchers themselves acknowledge that when factors like diabetes, genetics, and obesity are considered, the link to dementia vanishes. Additionally, no relationship was found between sugary drink consumption and stroke risk, despite this being a well-documented association. It is plausible that individuals already experiencing health issues, particularly those with diabetes, are more inclined to opt for zero-calorie beverages, which could distort the results.
In the meantime, many professionals recommend that all carbonated beverages, regardless of their sweeteners, should be consumed in moderation. Researchers have long studied the health risks associated with soda, with some suggesting a correlation with weight gain. In light of this recent study, the American Beverage Association released a statement emphasizing that international organizations such as the U.S. Food and Drug Administration, the World Health Organization, and the European Food Safety Authority have repeatedly assessed 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., becoming the largest beverage category by volume. Nationally, 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% drop in sales last year, while in Philadelphia, PepsiCo announced it would need to lay off 80 to 100 workers after a 40% sales decline following the city’s tax.
While the latest studies may not 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 are certainly not welcome news. As consumers look for healthier options, the demand for the best quality calcium citrate supplements and alternatives to soda will likely continue to grow.
