Thirty-eight patients (mean age, 48 years) with nonalcoholic
steatohepatitis received 20 g per day of whey protein for 12 weeks. The
mean plasma glutathione concentration increased significantly during the
treatment period. The mean serum alanine aminotransferase level
decreased from 64 U/L to 46 U/L (p < 0.02) and the mean aspartate
aminotransferase level decreased from 45 U/L to 33 U/L (p < 0.05).

Comment: Glutathione depletion is believed to play a role in the pathogenesis of nonalcoholic steatohepatitis, a common chronic condition that can lead to cirrhosis of the liver. Whey protein is rich in glutamylcysteine, which is a precursor to glutathione. Ingestion of whey protein has been reported to increase glutathione levels in various tissues. The results of the present study indicate that ingestion of whey protein was beneficial for patients with nonalcoholic steatohepatitis. Other interventions that may be of value include weight loss if overweight, avoidance of sucrose and high-fructose corn syrup, and supplementation with vitamin E.
