RESUMO
Soft drink is a carbonated water; flavoured and sweetened with either sugar or sweetener. The resulting glucose solution in the human body is the key source of energy. Positive associations between soft drinks consumption and incidence of diabetes have been postulated. Thus; it is the aim of this study to show the effects of casual soft drinks consumption on glucose level of healthy Nigerian individuals in fasting and 2 hours post-prandial. A total of 350 apparently healthy individuals were recruited for this study. 115 subjects (Group A) were given a bottle of Coca-Cola (Coke) each; another 115 (Group B) subjects were given a bottle of Bitter Lemon (Krest) each while the remaining 120 subjects (Group C) were given 75g of D-glucose in 300mL of distilled water. Glucose tolerance test (GTT) was performed on all the subjects and the curve of glucose concentration plotted against time of sample collection. GTT graph of group A and B shows a flat curve of enhanced GTT while group C shows a normal GTT response graph. The result however; indicates that casual consumption of soft drinks did not predispose to development of diabetes as it has no significant effect on plasma glucose and renal threshold concentration of apparently healthy individuals
