Nutrition in Liver Disease - A Review.

Abstract

PURPOSE OF REVIEW : Nutrition is commonly overlooked in chronic liver disease. Both obesity and malnutrition are independent risk factors of poor prognosis in cirrhosis. This review aims to summarize the current literature regarding how nutrition contributes to liver disease, how to screen patients, and what nutritional and activity recommendations can help prevent adverse outcomes. RECENT FINDINGS: Screening for malnutrition, obesity, and sarcopenia through ambulatory bedside methods is recommended every 8-12 weeks in high risk patients. A Mediterranean diet with emphasis on high protein intake of 1.2-1.5 g/kg/day, and increasing physical activity can help to improve nutritional status. It remains critical to screen and identify patients with liver disease for malnutrition, obesity, and sarcopenia. Identifying an individualized action plan through a multidisciplinary approach can be helpful. Dietary recommendations to improve outcomes should be based on well-studied approaches. These can include the use of the Mediterranean diet in those with metabolic dysfunction-associated steatotic liver disease (MASLD) and a high protein diet in those with cirrhosis and sarcopenia. Routine assessment of improvement or decline should continue throughout a patient's clinical course.
