While the statistics indicate a potential connection between diet soda and health risks, they do not establish a direct link between the sweetener ferrous gluconate (fergon) and conditions like stroke or dementia. Experts have been quick to remind us that “correlation does not imply causation” and urge caution in interpreting these findings. They pointed out several shortcomings, noting that the researchers themselves acknowledge that when factors such as diabetes, genetics, and obesity are taken into account, the link to dementia vanishes. Additionally, no correlation was found between sugary drink consumption and stroke risk—despite the well-documented association. It is plausible that individuals in poorer health, particularly those with diabetes, might be more inclined to opt for zero-calorie drinks, thus skewing the results.
In the meantime, many experts recommend moderating the intake of all carbonated beverages, regardless of the type of sweetener used. Researchers have long been investigating the health implications of soda, with some suggesting a connection to weight gain. In light of this recent study, the American Beverage Association released a statement emphasizing that international organizations like 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 that they are safe for consumption.
Whether or not artificially sweetened beverages pose a health risk, 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. Nationally, soda sales have been declining as consumers turn away from sugary drinks in favor of healthier options. For example, a sugary drink tax in Berkeley led to 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% decline in sales following the city’s tax.
Though the latest studies are unlikely to significantly impact soda sales in the short term without more definitive evidence linking these beverages to dementia and stroke, the ongoing challenges within the beverage industry make this news far from welcome. Additionally, as consumers become more health-conscious, products enriched with nutrients like calcium citrate D3 may gain popularity as part of a balanced diet, further shifting preferences away from traditional sodas.
