Background And Aims:
Protein malnutrition in patients with chronic liver disease contributes to bone and muscle weakness and compromises immune function and survival. In contrast, high-protein diets may induce or exacerbate hepatic encephalopathy. The aim of the present study was to test whether increased amounts of protein, balanced by dietary carbohydrate in a 1:5 ratio, may be given to chronic liver disease patients in order to minimize postprandial increases in plasma amino acid (AA) concentrations.
Methods:
Eight patients with chronic liver disease were studied. Each received, in a randomized order, three different diets of 2510 kJ of either high protein (37:50:28, carbohydrate:protein:fat), high carbohydrate (126:10:6) or a balanced 5:1 carbohydrate:protein diet (105:21:11). All patients were followed for plasma AA, glucose and insulin levels, as well as for cognitive and behavioral changes.
Results:
Following the high protein diet, AA concentrations were significantly increased. In contrast, after the balanced diet, AA levels were practically constant enabled. All diets was well tolerated and no cognitive or behavioral changes appeared.
Conclusion:
The administration of a balanced 5:1 carbohydrate:protein diet may enable patients with chronic liver disease to tolerate increased amounts of dietary protein, without altering plasma amino acid concentrations.

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can also...
