Soda may seem like a harmless daily pick-me-up, but experts warn it could quietly damage your liver over time. Gastroenterologist Dr. Vivian Asamoah cautions that even one sugar-sweetened soda a day can set the stage for fatty liver disease, a condition now common among people in their 20s and 30s. Unlike other organs, the liver often shows no early warning signs, meaning the damage can go unnoticed until it is advanced. With new research linking daily soda intake to scarring, inflammation, and long-term health risks, making small swaps today may help protect your liver and your future health.
How daily soda consumption harms the liver
Dr. Asamoah explains that the liver rarely signals early warning signs. Many of her young patients are shocked to be diagnosed with metabolic dysfunction-associated steatotic liver disease (MASLD), a condition previously known as non-alcoholic fatty liver disease.
The damage builds slowly and often unnoticed. According to a study published in the World Journal of Gastroenterology, just five to seven years of daily soda consumption can push the liver toward:
Left unchecked, these changes can lead to cirrhosis or liver failure. What makes soda particularly harmful is its high-fructose content. Unlike glucose, which can be used by multiple organs, fructose is almost entirely metabolised in the liver, overwhelming it and encouraging fat build-up.
Why young people are increasingly at risk
Dr. Asamoah stresses that fatty liver disease is not just an “older person’s problem.” She has diagnosed it in people in their 20s and 30s who otherwise appear healthy. The rise of soda and processed food consumption is a major driver behind this trend.
Fatty liver disease is also linked to other chronic health issues such as type 2 diabetes, obesity, and cardiovascular disease, meaning that soda can set off a cascade of health problems far earlier in life than expected.
Although medical advances are emerging—such as a recently approved GLP-1 medication for MASLD with fibrosis—these treatments are no substitute for prevention. Lifestyle choices, particularly reducing sugary drink intake, remain the most effective way to safeguard liver health.
Simple changes to protect your liver health
The encouraging news is that reducing soda intake can make a meaningful difference. Dr. Asamoah suggests swapping sugary drinks for healthier alternatives such as:
These small, daily swaps can lower sugar intake, support metabolism, and protect liver function over time. Beyond the liver, they also help regulate weight, improve energy levels, and reduce the risk of other chronic diseases.
Dr. Asamoah reminds people that prevention is always better than treatment. “Choosing water, sparkling water, or unsweetened tea instead of soda isn’t just cutting sugar, it’s protecting your liver, your energy, and your long-term health,” she says.
Even one soda a day can gradually damage the liver and lead to fatty liver disease, even in young adults. Since the liver often suffers silently, prevention through simple lifestyle choices, like swapping soda for healthier drinks, remains the best way to protect long-term health.

The damage builds slowly and often unnoticed. According to a study published in the World Journal of Gastroenterology, just five to seven years of daily soda consumption can push the liver toward:
- Fatty liver (MASLD): Caused by the build-up of fat from excess sugar and fructose.
- Fibrosis (scarring): Permanent damage that reduces liver efficiency.
- Chronic inflammation: Accelerates disease progression and increases long-term risk.
Left unchecked, these changes can lead to cirrhosis or liver failure. What makes soda particularly harmful is its high-fructose content. Unlike glucose, which can be used by multiple organs, fructose is almost entirely metabolised in the liver, overwhelming it and encouraging fat build-up.

The encouraging news is that reducing soda intake can make a meaningful difference. Dr. Asamoah suggests swapping sugary drinks for healthier alternatives such as:
- Water or sparkling water to stay hydrated without sugar.
- Unsweetened tea or coffee for flavour and antioxidants.
- Fruit- or herb-infused water to satisfy cravings naturally.
These small, daily swaps can lower sugar intake, support metabolism, and protect liver function over time. Beyond the liver, they also help regulate weight, improve energy levels, and reduce the risk of other chronic diseases.
