The purpose of this study is to investigate dietary factors which influence the conditions of Korean fatty liver patients. The subjects were 83 fatty liver patients living in city, ages of 10 to 60 yrs old, and they were the same patients studied 9 months ago in previous study. The patients were groupsed into 3 groups(improved, similar, worsened groups) according to the changes in disease condition. Nutrient and alcohol intakes and health status were investigated. In improved group, the patients tended to lose weight, the number of exercising patients was increased, the consumptions of calorie, carbohydrate, calcium, phosphorus were decreased. And alcohol intake was decreased markedly and serum total amino acids(AA), EAA, NEAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios were increased. In worsened group, patients tended to gain weight, the number of exercising patients decreased, the consumptions of calorie, protein, carbohydrate, calcium, phosphorus and niacin decreased but vitamin. A intake increased. And also, in this group, alcohol intake of male patients decreased and that of female slightly increased, and serum EAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios, and total fatty acid contents increased and total AA and NEAA contents decreased. In conclusion, it is desirable to reduced weight, stress, alcohol, salt and animal fat consumptions, and to exercise, and to take adequate amount and quality of protein to improve conditions of fatty liver patients.
