T A F Correa et al, 2013, Paper filtered coffee increases cholesterol and inflammation biomarkers independent of roasting degree, Nutrition, published online ahead of print.
Objective: The aim of this study was to compare the effects of medium light roast (MLR) and medium roast (MR) paper-filtered coffee on cardiovascular risk factors in healthy volunteers.
Methods: This randomized crossover trial compared the effects of consuming three or four cups (150 mL) of MLR or MR coffee per day for 4 wk in 20 healthy volunteers. Plasma lipids, lipoprotein( a) (Lp[a]), total homocysteine, and endothelial dysfunction–related inflammation biomarkers, serum glycemic biomarkers, and blood pressure were measured at baseline and after each intervention.
Results: Both roasts increased plasma total cholesterol, low-density lipoprotein-cholesterol, and soluble vascular cell adhesion molecule-1 (sVCAM-1) concentrations (10%, 12%, and 18% for MLR; 12%, 14%, and 14% for MR, respectively) (P < 0.05). MR also increased high-density lipoprotein cholesterol concentration by 7% (P =0.003). Plasma fibrinogen concentration increased 8% after MR intake (P = 0.01), and soluble E-selectin increased 12% after MLR intake (P = 0.02). No changes were observed for Lp(a), total homocysteine, glycemic biomarkers, and blood pressure.
Conclusion: Moderate paper-filtered coffee consumption may have an undesirable effect on plasma cholesterol and inflammation biomarkers in healthy individuals regardless of its antioxidant content.
