Biochemical effects of feeding soft drink and ethanol.

This work was undertaken to study whether consumption of alcoholic beverage mixed with soft drinks could reduce the metabolic effect caused by ethanol. When 24 hr fasted rats were intragastrically fed rum (with 40% ethanol) diluted (1:1) with water, 3.0 ml (0.5 g ethanol) per 100 g body weight and sacrificed 12 hr later in fasting condition, exhibited higher levels of triacyl glycerol, glucose, total cholesterol, high density lipoprotein (HDL), aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP) in serum, higher levels of total cholesterol, triacyl glycerol and thiobarbituric acid reactive substances (TBARS) in both liver and kidneys, and lower levels of serum albumin. When fasted rats were fed 3.0 ml soft drink (0.31 mg caffeine), they showed increased levels of triacyl glycerol, glucose, ALT and ALP in the serum, TBARS in liver and kidneys, triacyl glycerol and total cholesterol in kidneys and lower levels of serum albumin. Soft drink feeding did not reduce serum total cholesterol but reduced HDL levels. Also soft drink did not alter liver lipids. When a mixture of 1.5 ml diluted rum (0.25 g ethanol) and 1.5 ml soft drink (0.154 mg caffeine) were fed to the fasted rats, the serum parameters increased similar to rats fed rum only except that total cholesterol and HDL cholesterol were unaltered. TBARS in kidneys and liver were also increased but triacyl glycerol levels were not altered. Thus feeding ethanol with soft drink does not reduce the metabolic effects of ethanol but it will prevent ethanol induced serum HDL cholesterol rise.
