A study conducted by scientists at Washington University in St. Louis has shown that certain gut bacteria process sorbitol, thus protecting the liver from fat accumulation. This discovery, published in Science Signaling, sheds light on the relationship between diet, gut microbiota, and common liver diseases. The research found that the absence of bacteria that break down sorbitol can lead to fat accumulation in the liver. High sorbitol consumption, common in low-sugar processed foods (diet products), can exacerbate liver risk, especially in individuals with alterations in their gut microbiota. Experiments and Revelations: Scientists used zebrafish to investigate the impact of the gut microbiota on liver fat accumulation. By eliminating the gut microbiota, they observed that the fish accumulated fat in their livers in just one week. Even administering extra sorbitol caused lipid accumulation in the liver, even in fish with a healthy gut microbiota. Recolonization with sorbitol-degrading Aeromonas bacteria proved effective in reducing liver fat.

Implications of Dietary Sorbitol

The results suggest that high consumption of sorbitol, commonly used as a sugar substitute, may increase the risk of developing steatotic liver disease.

The research underscores the need to evaluate fructose sources, including those derived from sorbitol, in modern diets.

Recommendations and Future Research

The researchers advise caution in the consumption of sorbitol-rich products, highlighting the need for further studies in mammals and humans to validate these findings.

Strengthening the gut microbiota with specific bacteria may be key to preventing diet-related liver diseases.

To promote a healthy gut microbiota, which reduces the risk of liver disease, it is essential to follow a balanced diet rich in fiber, fermented foods, and healthy fats, while avoiding excessive consumption of saturated fats and ultra-processed foods. The consumption of probiotics and prebiotics also plays a vital role, as they help modulate the microbiota, reduce inflammation, and improve liver function. What other products contain cortisol? In addition to "light" products, sorbitol is found in high concentrations in various natural and processed foods. Fruits that naturally contain sorbitol include apples (especially green ones), pears, plums, peaches, cherries, apricots, dates, and dried fruits such as prunes and raisins. It is also present in some vegetables such as cauliflower, mushrooms, peas, celery, and red algae. As for processed foods, sorbitol is commonly used in products such as sugar-free gum and candy, low-calorie desserts and ice cream, sugar-free baked goods (such as cookies and muffins), syrups, low-sugar sauces, and light snacks or energy bars. Additionally, cane honey and molasses also contain high levels of sorbitol. Therefore, besides products labeled as "light," numerous fruits, vegetables, and processed products contain sorbitol, either naturally or as an additive to sweeten and preserve food.
