“…This is a new and potentially important addition to the already published finding that coffee consumption is negatively associated with diabetes risk. [4][5][6][7][8] It is based on the following evidence: first, there was a significant statistical interaction between age and beverage consumption; and only subjects r60 y of age exhibited a significant negative relationship between beverage consumption and diabetes risk. The negative relationship was found for ground-caffeinated coffee, ground-decaffeinated coffee, regular tea and caffeine itself.…”

Coffee, tea and diabetes: the role of weight loss and caffeine

et al. 2005

OBJECTIVE:To assess the effect of weight change on the relationship between coffee and tea consumption and diabetes risk. DESIGN: Prospective cohort study, using data from the First National Health and Nutrition Examination Survey Epidemiologic Follow Up Study. Survival analyses were conducted using 301 selfreported cases of diabetes and eight documented diabetes deaths during an 8.4-y follow-up. SUBJECTS: A total of 7006 subjects aged 32-88 y with no reported history of diabetes were included in the study. RESULTS: For all subjects combined, increases in consumption of ground-caffeinated coffee and caffeine at baseline were followed by decreases in diabetes risk during follow-up. There were significant statistical interactions between age and consumption of caffeine (P ¼ 0.02) and ground-caffeinated coffee (P ¼ 0.03). Age-stratified analysis showed that the decrease in diabetes risk only applied to r60-y-old subjects, for whom the decrease in diabetes risk also obtained for ground-decaffeinated coffee and regular tea. The multivariate hazard ratio (HR) and 95% confidence interval for a 2 cups/day increment in the intake of ground-caffeinated coffee, ground-decaffeinated coffee and regular tea was 0.86 (0.75-0.99), 0.58 (0.34-0.99) and 0.77 (0.59-1.00), respectively. The diabetes risk was negatively related to the consumption in a dose-response manner. There were strong statistical interactions between prior weight change and beverage consumption for r60-y-old subjects. Further analysis revealed that the decrease in diabetes risk only applied to those who had lost weight, and that there was a positive doseresponse relationship between diabetes risk and weight change. For example, the multivariate HR and 95% confidence interval for 40 vs 0 cups/day of ground-decaffeinated coffee was 0.17 (0.04-0.74), 0.52 (0.19-1.42), 0.77 (0.30-1.96) and 0.91 (0.39-2.14) for subgroups with weight change of r0, 0-10, 10-20 and 420 lbs, respectively. There was no significant association between diabetes risk and consumption of instant-caffeinated coffee, instant-decaffeinated coffee or herbal tea. Caffeine intake appeared to explain some, but not all, of the diabetes-risk reduction and weight change. CONCLUSION: The negative relationship between diabetes risk and consumption of ground coffee and regular tea, observed for all NHEFS subjects, actually only applied to nonelderly adults who had previously lost weight.

“…A prospective study performed in the Netherlands reported that coffee drinking was associated with a decreased risk of type 2 diabetes [6]. This finding has since been replicated in several follow-up and cross-sectional studies [7,8,9,10,11]. However, a health examination survey of the Finnish population [12] and a population-based study of Pima Indians [13] failed to observe a protective effect of coffee.…”

Coffee consumption and glucose tolerance status in middle-aged Japanese men

Aims/hypothesis. Several studies have reported that coffee has a protective effect against the development of type 2 diabetes. However, few of these studies used the standard glucose tolerance test to diagnose type 2 diabetes. The aim of this study was to investigate the relationship between coffee and green tea consumption and glucose tolerance status as determined using a 75-g OGTT. Methods. We performed a cross-sectional study of 3224 male officials of the self-defence forces. Glucose tolerance status was determined in accordance with the 1998 World Health Organization criteria, and average intakes of coffee and green tea over the previous year were assessed by a self-administered questionnaire. The figures obtained were adjusted for BMI, physical activity and other factors. Results.A total of 1130 men were identified as having glucose intolerance (IFG, IGT or type 2 diabetes). Compared with those who did not consume coffee on a daily basis, fasting and 2-h post-load plasma glucose levels were 1.5% and 4.3% lower in those who drank 5 cups of coffee or more per day respectively. The adjusted odds ratios of glucose intolerance for categories of <1, 1-2, 3-4 and ≥5 cups of coffee per day were 1.0 (referent), 0.8 (95% CI 0.6-1.0), 0.7 (95% CI 0.6-0.9) and 0.7 (95% CI 0.5-0.9) respectively (p=0.0001 for trend). No clear association was observed between green tea drinking and glucose tolerance status. Conclusions/interpretation. Coffee consumption may inhibit postprandial hyperglycaemia and thereby protect against the development of type 2 diabetes mellitus.

The mechanism of the association has not been clarified yet, but several plausible mechanisms have been suggested .…”

Objectives: To study the joint association of coffee consumption and serum g-glutamyltransferase (GGT) levels on the risk of developing type II diabetes. Design, setting and subjects: A total of 21 826 Finnish men and women who were 35-74 years of age and without any history of diabetes at baseline (years 1982, 1987, 1992 and 1997) were included in the present analyses. They were prospectively followed up for onset of type II diabetes (n ¼ 862 cases), death or until the end of the year 2002. Coffee consumption, serum GGT and other study parameters were determined at baseline using standardized measurements. Analyses were stratified by the serum GGT level classified into two classes using the 75th sex-specific percentiles as the cut point. Results: Coffee consumption was significantly and inversely associated with incident diabetes among both men and women. Serum GGT modified the association between coffee consumption and incident diabetes. Subjects in the high category of coffee consumption with the GGT level X75th percentile showed a significant inverse association for women, and for both sexes combined. The association was not significant in subjects with the GGT level p75th percentile. There was a significant interaction effect of GGT and coffee consumption on risk of type II diabetes in data of women (P ¼ 0.05) and in both sexes combined (P ¼ 0.02). Conclusions: Habitual coffee consumption is associated with lower incidence of type II diabetes particularly in those with higher baseline serum GGT levels.
