title: [Effect of ethanol adminstration in the consumption of proteins and nitrogen balance in normal subjects with normoprotein diet].
abstract: The effect of excessive alcohol intake on the protein requirements and metabolism in normal subjects has not been clearly determined. In this study we measured the nitrogen balance, the hematrocrit, the hemoglobin, the serum albumin, the cholesterol, and the plasmatic amino acids in 7 non-alcoholic subjects of 25 +/- 5 years of age. A comparison was made of a diet containing 0.8 g of protein per k of weight and 40 Kcal per k of weight administered during 11 days with a period of the same length in which the 1.400 Kcal provided during the control period by carbon hydrates was provided by ethanol (200 g). During the alcoholic period no importants changes were observed in the nitrogen balance, a tendency towards greater positivity being registered. There was a decrease in the serum albumin of 4, 69 +/- 0.31 vs 3, 90 +/- 0,32 g/100 ml and an increase in globulin 1,74 +/- 0,70 vs 2,69 +/- 0,22 g/100 ml. The results showed that in a short period of time the excessive alcohol intake in normal subjects does not increase the protein requirements in spite of a decrease in the serum albumin being observed.
