Hypothesis
Coffee and tea consumption are associated with lower insulin resistance, partly explained by plasma adiponectin and CRP concentrations.
Conclusion
The study suggests that habitual coffee consumption improves insulin sensitivity in Asians, without mediation by anti-inflammatory mechanisms.
Supporting Evidence
- Coffee consumption was inversely associated with insulin resistance.
- Green tea consumption was inversely associated with plasma C-reactive protein concentrations.
- Participants who consumed ≥ 3 cups of coffee per day had a significant reduction in insulin resistance.
Takeaway
Drinking coffee might help your body use sugar better, which is good for avoiding diabetes, but tea doesn't seem to help with that.
Methodology
Cross-sectional study examining coffee and tea consumption and their associations with glycemic and inflammatory markers.
Potential Biases
Potential for residual confounding due to self-reported lifestyle exposures.
Limitations
The study's cross-sectional design limits causal inferences, and self-reported dietary data may introduce measurement errors.
Participant Demographics
Multi-ethnic Asian population including Chinese, Malays, and Asian-Indians.
