Hypothesis
Does coffee consumption affect kidney function in healthy young adults?
Conclusion
Coffee consumption for two weeks increased cystatin-C-based estimated glomerular filtration rates and serum adiponectin levels in healthy young adults.
Supporting Evidence
- Coffee consumption increased cystatin-C-based eGFR by 5.0–7.7%.
- Serum adiponectin levels increased by 13.6% after coffee consumption.
- Creatinine-based eGFR was not significantly affected by either beverage.
Takeaway
Drinking coffee might help your kidneys work better, even if you only drink it for a little while.
Methodology
Nineteen healthy young adults consumed coffee or green tea for two weeks in a crossover design, measuring kidney function through cystatin-C-based eGFR.
Potential Biases
Potential bias due to the baseline differences in eGFR between coffee and green tea consumption.
Limitations
The study did not use standard GFR measurements and had a short duration, which may limit the applicability of the findings.
Participant Demographics
Nineteen asymptomatic nonsmokers aged 21–27 years old, including 8 men and 11 women.
