We evaluated the Parkia biglobosa pulp (PB) effects on food intake, body composition and oxidative and inflammatory parameters related to gut and brain of rats. A total of 32 male Wistar rats were randomised into four groups: healthy (HG), obese (OG); and healthy (HPB) and obese (OPB) groups with PB (400 mg/kg body weight). The rats consumed a control or cafeteria diet for 16 weeks. Body weight, food intake, bacteria count, organic acids in faeces were quantified. NF-κB and oxidative parameters were evaluated in the colon and hippocampus. PB contains fibres, 3,4-dihydroxybenzoic acid, catechin, and myricetin. PB treatment decreased fat mass and energy intake; increased the count of lactic acid bacteria and faecal organic acids, improved lipid peroxidation and reversed colon and hippocampal lesions, with reduction the NF-κB in OPB colon. PB has anti-obesity effect with potential to modulation gut-brain axis, mainly via blocking the activation of NF-κB.
