A recent study published in the ‘Journal of diabetes investigation’ reported that adults with type 2 diabetes who drink coffee had less decline in kidney function over time compared with non-coffee drinkers.

A total of 3,805 patients (2,112 men, 1,693 women) with type 2 diabetes (mean age 64.2 years) and eGFR ≥60 mL/min/1.73 m2 were followed (completion of follow up, 97.6%; median 5.3 years). Coffee consumption was assessed at baseline. The end-point was a decline in eGFR to < 60 mL/min/1.73 m2 during the follow-up period. During follow up, 840 participants experienced a decline in eGFR to < 60 mL/min/1.73 m2. Higher coffee consumption reduced the risk of decline in eGFR. Compared with no coffee consumption, the multivariate-adjusted hazard ratios (95% confidence intervals) were 0.77 (0.63–0.93) for less than one cup per day, 0.77 (0.62–0.95) for one cup per day and 0.75 (0.62–0.91) for two or more cups per day. This trend was unaffected by further adjustment for baseline eGFR and albuminuria.

The investigators opined that coffee consumption is significantly associated with a lower risk of decline in eGFR in patients with type 2 diabetes.
