The Effect of Caffeinated and Decaffeinated Coffee Consumption on Biochemical and Cardiac Parameters among Brazilians with Type 2 Diabetes
Aim: To analyze the effect of consuming caffeinated and decaffeinated coffee (coffea arabica) on biochemical and cardiac parameters among Brazilians with type 2 diabetes. Method: A random sample of 42 volunteers, in good cardiovascular condition, was divided into three groups: caffeinated coffee, decaffeinated coffee, and non-consumers. Results: After 6 months of monitoring, a reduction in glycemia (p<0.05) was observed in the caffeinated coffee group, and of triglycerides, among the moderate consumers (p<0.05). Among coffee consumers, independent of the type, there was reduction in platelets (p<0.05) and glycosuria. Both at baseline and at the end of the study, the active participants with moderate coffee consumption presented lower values of thyroxine (p<0.01). On the other hand, those who did not consume coffee presented higher values in miles walked (p<0.05) and in the volume of oxygen consumed per minute (p<0.01) at the end of the study. We also observed that coffee consumers, independent of type, presented lower metabolic equivalent values (p<0.01). Conclusion: Among the consumers of caffeinated coffee, there was improvement in the serum levels of glycemia, triglycerides and platelets. Among non-consumers, however, there was improvement of some cardiac indicators, such as miles walked and volume of oxygen consumed per minute.
