Berlin, Germany – October 20, 2025 – A groundbreaking investigation presented at UEG Week 2025 has revealed a surprising connection between the consumption of both sugar-sweetened beverages (SSBs) and low- or no-sugar-sweetened beverages (LNSSBs) and a heightened risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD). The extensive study, which analyzed data from over 123,000 adults in the United Kingdom, casts doubt on the long-held belief that diet drinks are a harmless substitute for sugary options.
What the Research Showed
Researchers followed participants from the UK Biobank who initially displayed no signs of liver ailments. Detailed dietary records, gathered through repeated 24-hour questionnaires, allowed for a meticulous examination of the relationship between beverage intake and liver health outcomes. the findings indicated a significant increase in MASLD risk for high consumers of both types of drinks.
Specifically, individuals who consumed over 250 grams daily faced ample risks. Those drinking LNSSBs exhibited a 60% higher likelihood of developing MASLD,while those favoring ssbs showed a 50% increase. Over a 10.3-year follow-up period, 1,178 participants were diagnosed with MASLD, and 108 individuals unfortunately succumbed to liver-related complications. Notably, LNSSB consumption was directly linked to liver-related deaths, while SSBs showed no significant association with mortality.
MASLD: A Growing Global Health Concern
MASLD, formerly known as non-alcoholic fatty liver disease (NAFLD), is characterized by an excessive buildup of fat in the liver. Left unchecked, this condition can escalate to inflammation and potentially lead to serious symptoms like abdominal discomfort, persistent fatigue, and decreased appetite. Currently, MASLD affects over 30% of the global population and is rapidly evolving into a primary driver of liver-related fatalities, according to a 2023 study in Journals.
Why Both Types of Drinks Pose risks
Lead researcher Lihe Liu emphasized that while SSBs have long been under scrutiny, their low-sugar alternatives haven’t received the same level of attention. “Our study demonstrates that LNSSBs were actually associated with a greater risk of MASLD, even with consumption as low as a single can per day,” Liu stated. “This challenges the widely held assumption that these drinks are benign and underscores the necessity to reassess their impact on liver health, especially given the escalating global prevalence of MASLD.”
Liu explained the potential biological mechanisms at play. The high sugar content in SSBs can induce rapid fluctuations in blood glucose and insulin, encourage weight gain, and elevate uric acid levels, all factors contributing to liver fat accumulation. simultaneously occurring,LNSSBs might disrupt the gut microbiome,interfere with satiety signals,promote sugar cravings,and even stimulate insulin secretion.
Key Findings Summarized
| Beverage Type | Daily Consumption Threshold | MASLD Risk Increase | liver-Related Mortality Risk |
|---|---|---|---|
| Sugar-Sweetened Beverages (SSBs) | >250 grams | 50% | Not Significant |
| Low/No-Sugar-Sweetened Beverages (LNSSBs) | >250 grams | 60% | Significant |
Did You Know? Replacing sugary or diet drinks with water can reduce your risk of MASLD by as much as 15.2%.
the Best Beverage Choice?
The research team strongly advocates for limiting the intake of both SSBs and LNSSBs as part of a comprehensive strategy to prevent not onyl liver disease but also broader cardio-renal-metabolic health issues. They found that substituting either type of beverage with water led to a noticeable reduction in MASLD risk-12.8% for SSBs and 15.2% for LNSSBs. However, swapping between the two types of drinks provided no discernible benefit.
“The most prudent approach is to minimize consumption of both sugar-sweetened and artificially sweetened drinks,” Liu advised. “Water remains the optimal choice, as it supports metabolic function and minimizes fat accumulation in the liver, while effectively hydrating the body.”
Pro Tip: Carry a reusable water bottle and refill it throughout the day to stay hydrated and reduce your temptation to reach for sugary or diet drinks.
Future research Directions
The researchers are now planning more in-depth investigations to unravel the underlying causal mechanisms. These future studies will involve long-term, randomized trials and genetic analyses, with a focus on understanding how sugar and its substitutes interact with the gut microbiome and influence the progress of liver disease.
Understanding Liver Health
Maintaining a healthy liver is crucial for overall well-being. Beyond beverage choices, factors such as a balanced diet, regular exercise, and maintaining a healthy weight play a vital role in liver health.

Frequently Asked Questions About Liver Disease and Beverages
- What is MASLD? MASLD, or metabolic dysfunction-associated steatotic liver disease, is a condition where excess fat builds up in the liver, potentially leading to inflammation and damage.
- Are diet drinks truly a healthy option to sugary drinks? This research suggests that diet drinks may not be as harmless as previously thought, and can actually increase the risk of MASLD.
- How much sugary beverage is too much? Consuming more than 250 grams of sugar-sweetened beverages per day is linked to a 50% increased risk of MASLD.
- Can simply switching to water improve my liver health? Yes, replacing sugary or diet drinks with water can significantly reduce your risk of developing MASLD.
- What other factors contribute to liver disease? Beyond beverage choices, factors like obesity, poor diet, and lack of exercise play significant roles in liver health.
- Is there a safe level of LNSSB consumption? This study indicates that even moderate intake of LNSSBs, such as one can per day, may increase MASLD risk.
- What are the early symptoms of liver disease? Early symptoms can be subtle, but may include fatigue, abdominal pain, and loss of appetite.

How might the disruption of the gut microbiome by artificial sweeteners contribute to liver damage?
The Artificial Sweetener Connection & Liver Health
For years,diet sodas have been marketed as a healthier alternative to sugar-sweetened beverages,often touted for weight management and diabetes control. However, emerging scientific evidence suggests a concerning link between regular consumption of diet soda and increased risk of liver damage, non-alcoholic fatty liver disease (NAFLD), and other related health issues. This isn’t about the sugar you avoid; it’s about what you’re replacing it with. The primary culprits are artificial sweeteners.
How Artificial Sweeteners Impact the Liver
The liver plays a crucial role in metabolizing everything we consume, including artificial sweeteners. Unlike natural sugars, these synthetic compounds aren’t easily broken down. This metabolic burden can lead to several problems:
* Gut Microbiome Disruption: Artificial sweeteners can considerably alter the composition of the gut microbiome. An imbalanced gut contributes to inflammation, which directly impacts liver function. Studies show a correlation between altered gut flora and increased liver enzyme levels, indicating liver stress.
* Increased Fatty Acid Synthesis: Some research suggests that certain artificial sweeteners, like sucralose, can stimulate de novo lipogenesis – the creation of new fat in the liver. This contributes to the growth of NAFLD.
* Metabolic Syndrome link: Frequent diet soda consumption is often associated with metabolic syndrome, a cluster of conditions (high blood pressure, high blood sugar, unhealthy cholesterol levels, and abdominal fat) that significantly increases the risk of liver disease.
* Fructose Metabolism Interference: Even though diet sodas don’t contain sugar, some artificial sweeteners are metabolized in a way that mimics fructose. Excessive fructose intake is a known contributor to NAFLD.
Specific Artificial Sweeteners & Their Liver Effects
Let’s break down the potential impact of some common diet soda sweeteners:
* Aspartame: One of the most widely used artificial sweeteners, aspartame has been linked to oxidative stress in the liver. Oxidative stress damages liver cells and contributes to inflammation.
* Sucralose: While often considered “safe,” studies indicate sucralose can alter gut bacteria and possibly increase intestinal permeability (“leaky gut”), leading to increased liver exposure to toxins.
* Saccharin: Early research raised concerns about saccharin and bladder cancer, but more recent studies focus on its potential to disrupt gut health and contribute to glucose intolerance, indirectly impacting liver function.
* Acesulfame Potassium (Ace-K): Often used in combination with other sweeteners,Ace-K’s long-term effects on liver health are still being investigated,but preliminary studies suggest potential metabolic disturbances.
Recognizing the Symptoms of Liver Issues
Early stages of liver disease often have no noticeable symptoms. However, as the condition progresses, you might experience:
* Fatigue
* Abdominal pain or swelling
* Loss of appetite
* Nausea
* Jaundice (yellowing of the skin and eyes)
* dark urine
* Pale stools
If you experience any of these symptoms, especially if you are a regular diet soda consumer, it’s crucial to consult a healthcare professional.
NAFLD & Diet Soda: A Growing Concern
Non-alcoholic fatty liver disease (NAFLD) is becoming increasingly prevalent, and diet soda consumption appears to be a contributing factor. NAFLD can progress to more serious conditions like non-alcoholic steatohepatitis (NASH), cirrhosis, and even liver cancer.
Case Study: The Impact on a Long-Term Diet Soda Drinker
A 48-year-old male patient, consuming 3-4 diet sodas daily for over 20 years, presented with elevated liver enzymes during a routine check-up. Further investigation revealed mild NAFLD. After eliminating diet soda from his diet and adopting a healthier lifestyle, his liver enzyme levels significantly improved within six months. This case, while individual, highlights the potential reversibility of early-stage liver damage with dietary changes.
Beyond Diet Soda: Other Liver-Harmful Habits
While diet soda is a meaningful concern,other lifestyle factors can also contribute to liver damage:
* Excessive Alcohol Consumption: A leading cause of liver disease.
* Unhealthy Diet: high in processed foods, saturated fats, and refined carbohydrates.
* Lack of Exercise: Physical inactivity increases the risk of NAFLD.
* Certain medications: Some medications can be toxic to the liver.
* Exposure to Toxins: Environmental toxins and pollutants can damage liver cells.
Protecting Your liver: Practical Tips & Alternatives
taking proactive steps to protect your liver is essential. Here are some actionable strategies:
- Reduce or Eliminate Diet Soda: This is the most impactful change you can make.
- Hydrate with Water: Prioritize water as your primary beverage
