Imagine reaching for a fizzy soda to quench your thirst each day – but what if that seemingly innocent habit is quietly putting your liver at serious risk? A groundbreaking UK study has just shed light on this alarming connection, revealing that sipping just one can of carbonated drinks, whether loaded with sugar or labeled as 'diet,' can significantly boost the chances of developing liver disease. Stick around to uncover the details, and prepare for some eye-opening insights that might just change how you view your beverage choices.
This fresh research, shared at the European Gastroenterology Conference (UEG) Week 2025, tracked the habits of 123,788 adults who began the study without any existing liver issues. Over roughly a decade, scientists used detailed 24-hour dietary surveys to explore how sugar-sweetened beverages (SSBs) and low- or no-sugar sweetened beverages (LNSSBs) relate to metabolic dysfunction-associated steatotic liver disease (MASLD). And this is where it gets intriguing – the findings didn't just point fingers at sugary drinks; they also implicated their supposedly healthier counterparts.
Participants who downed more than 250 grams of these drinks daily – that's about the amount in one standard can – faced markedly elevated risks. Those favoring LNSSBs had a 60% higher likelihood of MASLD, while SSB fans saw a 50% increase. After an average follow-up of 10.3 years, 1,178 people developed MASLD, and tragically, 108 passed away from liver-related causes. Interestingly, SSBs weren't strongly tied to those deaths, but 'diet' drinks were. Both categories, though, correlated with increased fat buildup in the liver.
To help newcomers understand, MASLD – formerly known as non-alcoholic fatty liver disease (NAFLD) – is a condition where too much fat accumulates in the liver, even without heavy alcohol use. This can lead to inflammation, causing symptoms like belly discomfort, constant tiredness, and a reduced desire to eat. It's now the world's leading chronic liver ailment, impacting over 30% of the population and playing a growing role in liver fatalities. Picture it as your liver becoming overburdened with fat, much like how a clogged drain slows water flow – but in this case, it disrupts your body's vital functions.
Lead researcher Lihe Liu pointed out that while sugary sodas have faced scrutiny for years, 'diet' versions are often seen as safe alternatives. Yet, the study flips the script, showing that both are ubiquitous in our diets and their impacts on liver health have been underestimated. 'Our findings indicate that low- or no-sugar drinks are connected to a greater MASLD risk, even with moderate consumption like a single can daily,' Liu remarked.
But here's where it gets controversial – are we underestimating the 'diet' drinks we thought were harmless? The study challenges the widespread assumption that artificial sweeteners make these beverages a guilt-free option. Liu delved into the potential reasons, explaining that the high sugar in SSBs can cause spikes in blood sugar and insulin, encourage weight gain, and elevate uric acid, all fueling fat storage in the liver. On the flip side, LNSSBs might harm the liver by reshaping the gut microbiome – that's the community of bacteria in your digestive system – messing with your sense of fullness, sparking intense sweet cravings, and possibly triggering insulin release.
The experts stress that cutting back on both SSBs and LNSSBs is essential for liver and overall metabolic well-being. Swapping either type for plain water slashed MASLD risk by 12.8% for SSBs and 15.2% for LNSSBs, but replacing one fizzy drink with another didn't help at all. 'The wisest strategy is to curb both sugar-filled and artificially sweetened drinks. Water is the superior pick because it eases metabolic strain, wards off liver fat accumulation, and keeps you properly hydrated,' Liu advised.
Looking ahead, more studies are planned to delve deeper into how sugars and sweeteners interact with the gut microbiome and drive liver issues, including long-term trials and genetic analyses.
