ABSTRACT
The objective of this study was to evaluate the effect of roasting coffee degree on inflammatory (NF-kß F-6 and TNF-α) and stress oxidative markers (malondialdehyde (MDA), nitric oxide (NO) end product concentrations, catalase (CAT), and superoxide dismutase (SOD) in high-fructose and saturated fat (HFSFD)-fed rats. Roasting was performed using hot air circulation (200 °C) for 45 and 60 min, obtaining dark and very dark coffee, respectively. Male Wistar rats were randomly assigned to receive a) unroasted coffee, b) dark coffee, c) very dark coffee, or distilled water for the control group (n = 8). Coffee brews (7.4 mL/per day equivalent to 75 mL/day in humans) were given by gavage for sixteen weeks. All treated groups significantly decreased NF-kß F-6 (â¼30 % for unroasted, â¼50 % for dark, and â¼ 75 % for very dark group) and TNF-α in the liver compared with the control group. Additionally, TNF-α showed a significant reduction in all treatment groups (â¼26 % for unroasted and dark groups, and â¼ 39 % for very dark group) in adipose tissue (AT) compared with the negative control. Regarding oxidative stress makers, all coffee brews exerted antioxidant effects in serum, AT, liver, kidney, and heart. Our results revealed that the anti-inflammatory and antioxidant effects of coffee vary according to the roasting degree in HFSFD-fed rats.
