Richmond, Virginia – A recent study conducted by researchers from Virginia Commonwealth University’s School of Medicine and Richmond VA Medical Center has shown promising results for liver patients suffering from cirrhosis. The study, published in the Clinical and Translational Gastroenterology journal, found that switching to a vegan or vegetarian diet for just one meal can significantly reduce harmful ammonia levels in adults with liver damage.
In the study, a group of 30 carnivorous adults with liver cirrhosis were presented with different meal options containing 20 grams of protein. The participants were divided into three groups: one group received a meat-based patty, another group was given a vegan meat substitute, and the remaining individuals were served a vegetarian bean burger. Researchers also provided low-fat potato chips, a whole-grain bun, and water, with no condiments or toppings allowed.
Blood and urine samples were taken before and after the meal, revealing that participants who consumed the meat burger had higher amino acid levels associated with ammonia production and hepatic encephalopathy compared to those who opted for non-meat alternatives. Hepatic encephalopathy is a brain disorder resulting from severe liver damage.
The findings suggest that gut bacteria and diet play a crucial role in influencing ammonia levels in individuals with cirrhosis. Dr. Jasmohan Bajaj, a gastroenterologist from VCU, emphasized the importance of dietary changes, stating that even small adjustments like incorporating meatless meals can benefit liver health by reducing harmful ammonia levels.
While further research is needed to explore the impact of vegan diets on cirrhosis and ammonia levels, the researchers hope that physicians will encourage patients with liver disease to replace meat with protein sources from plants or dairy. Making positive changes in diet, even simple ones like skipping meat for a meal, can have significant benefits for liver health without being overwhelming or difficult for patients.
