We all know the refreshing feeling of relaxing with a cold soda—after a long day, during a movie night, or on a hot summer afternoon. Many people choose diet sodas believing they are a healthier option. However, new research suggests that even small amounts may have potential health implications.
A study presented on October 6 at the 2025 United European Gastroenterology Week conference in Berlin examined the effects of both sugary and artificially sweetened beverages on liver health. Researchers found that regular consumption—even less than one can per day—was associated with a higher likelihood of developing liver-related conditions.
According to the study, drinking as little as 9 ounces of a sugar-sweetened beverage per day was linked to a significantly increased risk of Metabolically Dysregulated Steatotic Liver Disease (MASLD). Surprisingly, similar amounts of diet soda were associated with a comparable or even higher risk.
MASLD, previously known as non-alcoholic fatty liver disease, is one of the most common liver conditions worldwide. It involves fat accumulation in the liver and, over time, may progress to more serious complications.
The study’s lead author explained that sugary drinks may contribute to liver fat through blood sugar spikes and metabolic strain. Meanwhile, artificially sweetened beverages may influence liver health by affecting gut bacteria, appetite regulation, and insulin response.
Health experts have long cautioned against excessive soda consumption. While diet sodas are often viewed as a safer alternative, this research suggests that moderation remains important for both sugary and sugar-free drinks.
Nutrition professionals emphasize that water, unsweetened tea, and naturally flavored beverages are healthier everyday choices. Reducing reliance on sweetened drinks—whether diet or regular—may support long-term liver and metabolic health.See More
