Carbohydrate-related regulation of the ethanol-induced increase in serum gamma-glutamyl transpeptidase activity in adult men.
The dietary influence on ethanol-induced increase in serum gamma-glutamyl transpeptidase (gamma-GTP) activity was studied in 2165 healthy men 18-85 y of age living in Nagano Prefecture, Japan. As ethanol consumption increased, the intake of cereals, potatoes, vegetables, milk and dairy products, oils, fruit, confections, and sugar decreased, whereas the intake of meat increased. These associations suggest that ethanol consumption led to the decrease in the intake of carbohydrate and vegetable fat. Serum gamma-GTP activity was found to be positively related to ethanol consumption and negatively related to the intake of sugar, fruit, and confections. The activity was the highest in those whose percent energy intake from carbohydrates was the lowest. Stepwise-multiple-regression analysis identified the three variables ethanol, sugar, and fruit, as the factors associated with the value of gamma-GTP activity: ethanol on the one hand increased the activity, whereas sugar and fruit on the other hand decreased the activity. Moreover, a lowered sugar intake augmented the ethanol-induced increase in the enzyme activity. These results suggest that sugar intake plays a role in the ethanol-induced increase in serum gamma-GTP activity.
