A major new study has revealed potential risks to liver health associated with artificially sweetened beverages, often marketed as “diet” drinks. Findings presented at the United European Gastroenterology Week in Berlin indicate that consuming just one can per day of these drinks may increase the risk of metabolic dysfunction-associated steatotic liver disease (MASLD) by 60%, surpassing the 50% risk linked to sugary drinks. This challenges the perception that diet drinks are a healthier alternative. The study, which tracked 123,788 participants over a decade, highlights how both sugary and artificially sweetened beverages contribute to liver fat accumulation and increased mortality from liver-related diseases. Artificial sweeteners were found to disrupt the gut microbiome and satiety signals, potentially exacerbating sweet cravings and insulin secretion. In Malta, where the Mediterranean diet is celebrated for its health benefits, these findings underscore the importance of reconsidering beverage choices. Lifestyle changes, such as replacing sugary and artificially sweetened drinks with water, can significantly reduce liver disease

Are Diet Drinks a Hidden Risk to Your Liver Health? New Research Sheds Light

A major new study has raised concerns about the health risks associated with artificially sweetened beverages, commonly marketed as “diet” drinks. Surprisingly, just one can per day of these drinks could pose a greater risk to liver health than their sugary counterparts. This revelation is particularly relevant as metabolic dysfunction-associated steatotic liver disease (MASLD) – a condition caused by fat accumulation in the liver – now affects over 30% of the global population.

The findings, presented at the United European Gastroenterology Week in Berlin, challenge the long-held assumption that diet drinks are the healthier alternative. “Sugar-sweetened beverages (SSBs) have long been criticized, but their ‘diet’ alternatives are often seen as safe,” said Lihe Liu, the study’s lead author and a researcher in gastroenterology at the First Affiliated Hospital of Soochow University, China. “Our study refutes this notion, showing that even a single can of artificially sweetened drinks per day increases the risk of liver disease.”

The decade-long research involved 123,788 participants from the UK Biobank who initially had no liver disease. Their beverage consumption was tracked through detailed dietary questionnaires. The results were striking: sugary drinks raised the risk of MASLD by 50%, while artificially sweetened beverages increased the risk by 60%.

The Impact of Sweetened Drinks on Liver Health

Both sugar-laden and artificially sweetened beverages were linked not only to liver fat accumulation but also to increased mortality from liver-related diseases. Sugary drinks, with their high sugar content, can rapidly spike blood sugar and insulin levels, promote weight gain, and elevate uric acid levels – all of which contribute to liver fat buildup. Meanwhile, artificially sweetened drinks disrupt the gut microbiome, interfere with satiety signals, and may even stimulate sweet cravings and insulin secretion.

In Malta, where the Mediterranean diet is often celebrated for its health benefits, these findings are a wake-up call. Many people turn to diet drinks as a perceived “healthier” option, especially when dining out or enjoying takeaway meals. However, this study emphasizes the need for greater awareness about the impact of these beverages on long-term health.

A Call for Lifestyle Changes

The NHS outlines four stages of MASLD, beginning with simple fat accumulation in the liver (a common condition) and progressing to more serious liver damage in a small percentage of individuals. The good news? Lifestyle changes, including dietary adjustments, can prevent the disease from advancing.

The study’s authors highlighted a straightforward way to reduce risk: replace sugary and artificially sweetened drinks with water. This simple swap lowered the risk of liver disease by over 10%. “Water is the safest and most effective choice,” Liu explained. “It alleviates the metabolic burden, prevents fat buildup in the liver, and hydrates the body.”

How to Make Healthier Choices When Dining Out in Malta

For those in Malta looking to balance their love for dining out with a commitment to health, these findings are especially relevant. Many restaurants across the island are now offering healthier drink alternatives, such as infused waters, herbal teas, and freshly squeezed juices. When selecting beverages, opt for options that align with a Mediterranean-style diet, which is naturally rich in liver-friendly foods like fresh vegetables, olive oil, and lean proteins.

Additionally, consider asking your favorite restaurants if they offer non-sweetened alternatives to sodas or artificially sweetened drinks. Many establishments are happy to accommodate requests for healthier options and even create bespoke drinks using natural ingredients.

A Mediterranean Approach to Liver Health

As MASLD emerges as a global health concern, Malta’s culinary traditions offer a solid foundation for prevention. The Mediterranean diet, known for its emphasis on fresh, whole foods, can play a pivotal role in reducing liver fat and supporting overall health. Incorporating foods like fish, nuts, whole grains, and leafy greens into your meals – and pairing them with water or unsweetened beverages – is a powerful way to protect your liver.

While the occasional indulgence is part of enjoying life, this research serves as a reminder to be mindful of daily habits. Whether at home or dining out, small changes like prioritizing water over sugary or diet drinks can make a significant difference in your long-term health.

The Bottom Line

Both sugary and artificially sweetened drinks come with health risks, particularly for liver health, and should be consumed in moderation. Water remains the best choice for hydration and metabolic health. For those in Malta, embracing the island’s Mediterranean heritage and prioritizing natural, whole foods can help mitigate these risks while enhancing both physical and mental well-being.

So, the next time you’re enjoying a meal at your favorite restaurant or planning your weekly shop, remember: your liver will thank you for choosing water – the simplest, healthiest drink of all.
