HUAMAN-SAAVEDRA, Juan Jorge et al. Effect of regular and decaffeinated coffee consumption on glycemia in young adults. Acta méd. peruana [online]. 2015, vol.32, n.1, pp.15-19. ISSN 1728-5917.

Goal. Evaluate the effect of consumption of regular coffee and decaffeinated coffee on glycemia in young adults. Material and Methods. Experimental design. Were selected 42 students from Medical School, divided into three groups; which consumed; G1: regular coffee, G2: decaffeinated coffee, G3: a placebo. The glycemia was measured, by the oral glucose tolerance test (OGTT), to the beginning, at 4 weeks and 8 weeks. The data were evaluated by t of student’s test for related samples before and after test in each group. Statistics: ANOVA and Tukey test; with significance p < 0,05. results. Before the test with coffee, the glucose level in G1, G2 and G3 at 0 minutes of OGTT was 91,07, 91,86 and 94,14 mg/dL, respectively, and 114,07 mg/dL, 116,50 and 110,57 mg/dL at 120 minutes, respectively. At 8 weeks, at 0 minutes of OGTT, G1 had 87,64 mg/dL; G2, 95,57 mg/dL and G3, 95,57 mg/dL glycemia without significant changes; and at 120 minutes: G1 had 98 mg/dL with a significant decrease (14,09 %); G2, 123,29 mg/dL and G3, 113,21 mg/dL without significant changes. Conclusion. The consumption of regular coffee decrease glycemia significantly at 120 minutes of OGTT, in young adults.
