Filtered coffee

1. Filtered coffee decreases KDM biological age in humans (β = -1.118 [95% CI -1.415 to -0.820]).

   “The negative association between filtered coffee consumption and KDM-BA Accel was observed (0-1 cup per day: β = -0326 [-0.437 to -0.215]; 1-3 cups per day: β = -0.762 [-0.879 to -0.646]; >3 cups per day: β = -1.118 [-1.415 to -0.820]; P-trend < 0.001)”
