Tietääkönä täällä kukaan näistä plagiointijutuista mitään.
Jos ei nyt ihan plagiointia niin ainakin hyvän tavan vastaista jättää primaarilähde pois..
Mun paperi:
"PROTEIN INTAKE AND LIVER FUNCTION
AHA Nutrition Committee suggests that high-protein intake may have detrimental effects on liver function. However, there is no scientific evidence whatsoever supporting this contention. Protein is needed not only to promote liver tissue repair, but also to provide lipotropic agents such as methionine and choline for the conversion of fats to lipoprotein for removal from the liver, thus preventing fatty infiltration.20
Rodents fed very high protein intakes have been found to exhibit morphological changes in the liver mitochondria, which could be pathological. However, Jorda et al. reported that the liver responds to the high-protein diet by a proliferation of normally functioning mitochondria.24 Further, the branched-chain amino acids to aromatic amino acids ratio was also increased, indicating the absence of hepatic failure in these animals. Authors concluded that “the increased protein content of diet induced rapid increases in several characteristics of hepatocytes… The results presented here constitute a good example of how the hepatocyte adapts to a continuing metabolic stress.”
Further, protein catabolism is increased in liver disease and may be exacerbated by inadequate protein in the diet.19 Unless there is encephalopathy (vide infra), the diet should provide high-quality protein in the amount of 1.5 to 2 g/kg.19 In alcoholic liver disease, a high-calorie, high-protein diet has been shown to improve hepatic function and reduce mortality. In one study, this was achieved by providing a regular diet plus supplements of 60 g/day of protein and 1600 kcal/day for the first 30 days and followed by supplements of 45 g/day of protein and 1200 kcal/day for the next 60 days.21"

"The American Heart Association has suggested that high protein diets may have detrimental effects on liver function (St. Jeor et al., 2001). This is primarily the result of a concern that the liver will be stressed through metabolizing the greater protein intakes. However, there is no scientific evidence to support this contention. Jorda and colleagues (1988) did show that high protein intakes in rats produce morphological changes in liver mitochondria. However, they also suggested that these changes were not pathological, but represented a positive hepatocyte adaptation to a metabolic stress.
Protein is important for the liver not only in promoting tissue repair, but to provide lipotropic agents such as methionine and choline for the conversion of fats to lipoprotein for removal form the liver (Navder and Leiber, 2003a). The importance of high protein diets has also been acknowledged for individuals with liver disease and who are alcoholics. High protein diets may offset the elevated protein catabolism seen with liver disease (Navder and Leiber, 2003b), while a high protein diet has been shown to improve hepatic function in individuals suffering from alcoholic liver disease (Mendellhall et al., 1993)."
