A recent study has uncovered alarming findings regarding the consumption of both sugary sodas and diet drinks, suggesting that individuals may be at a higher risk of developing fatty liver disease. Researchers presented their findings on Monday at the United European Gastroenterology's annual meeting in Berlin, revealing that artificially sweetened beverages might pose an even greater threat to liver health than their sugary counterparts.
The study, led by Lihe Liu, a graduate student in gastroenterology at the First Affiliated Hospital of Soochow University in Suzhou, China, highlights the need to reevaluate the perception of these beverages. While sugar-sweetened beverages have long been scrutinized for their health implications, diet drinks are often mistakenly viewed as a healthier alternative. Liu emphasized in a news release that the findings challenge the belief that these drinks are harmless and underscore their potential negative impact on liver health.
Fatty liver disease is a condition characterized by the accumulation of fat in the liver, which can lead to severe liver damage over time. According to researchers, it is currently the most common chronic liver disease, affecting over 30% of the global population. The implications of this study are significant, as they suggest that both sugary and artificially sweetened beverages could contribute to an increased risk of this condition.
For this extensive study, researchers analyzed data from nearly 124,000 participants in the U.K. Biobank, a long-term health study in the United Kingdom. Participants documented their beverage intake through a 24-hour dietary questionnaire. Over a median follow-up period of 10 years, the study observed that nearly 1,200 participants developed fatty liver disease, and 108 individuals died from liver-related causes.
The results were striking. Consumption of approximately nine or more ounces of artificially sweetened beverages daily was associated with a 60% increased risk of developing fatty liver disease. In comparison, regular consumption of sugary beverages was linked to a 50% increased risk. Liu noted, “Our study shows that low- or non-sugar-sweetened beverages were actually linked to a higher risk of fatty liver disease, even at modest intake levels such as a single can per day.”
Interestingly, the study also found that replacing both sugary and artificially sweetened beverages with water led to a significant reduction in the risk of fatty liver disease. Specifically, individuals who opted for water instead of artificially sweetened drinks lowered their risk by more than 15%, while replacing sugary beverages with water resulted in a nearly 13% risk reduction.
Liu explained that the high sugar content present in sugary drinks can cause rapid spikes in blood sugar levels, promote weight gain, and increase uric acid levels—all of which are associated with fat accumulation in the liver. Conversely, artificially sweetened beverages may negatively impact liver health by altering the gut microbiome, increasing cravings for sweets, and stimulating insulin secretion.
The lead researcher concluded that the safest strategy is to limit the intake of both sugary and artificially sweetened drinks. “Water remains the best choice,” Liu stated, as it helps eliminate metabolic burdens and prevents fat accumulation in the liver while keeping the body hydrated.
Looking ahead, researchers plan to investigate the underlying reasons why these beverages contribute to increased liver fat accumulation through long-term clinical trials. As with all findings presented at medical meetings, these results should be considered preliminary until published in a peer-reviewed journal.
