  ABSTRACT: Chronic intake of High Fat Diet (HFD) has the potential of causing a number of metabolic disorders. It is also theorized to be involved in perturbation of gut microbiota. Cannabididol (CBD) and omega 3 are known to possess a number of medicinal usefulness. Their combined use in experimental interventions is quite limited. A total of 15 mice were used for this research divided into three groups of five animals each. Group 1 was administered water and normal chow ad libidum. Group 2 had HFD and water ad libidum. Group 3 had HFD plus CBD (10 mg/kg) and omega 3 (200 mg/kg) all for a total of 12 weeks. They were tested on the elevated plus maze (EPM) and average entry time into the closed arm was recorded. They were also tested on the Y-maze and spontaneous alternations were measured. Thereafter animals were sacrificed and faecal content in the caecum was collected in sterile bottles and cultured for E. coli count. It was found that HFD group at p value E. coli count (2.4 × 106 ± 4.5) compared to group 1 (1.4 × 106 ± 5.6) and group 3 (1.42 × 106 ± 6.3). The findings revealed that HFD enhanced gut E. coli overgrowth which was reduced by CBD and Omega 3. The memory impairment and anxiety induction by HFD was also significantly ameliorated by CBD and omega 3. E. coli known to be implicated in dementia induction was suppressed by the interventions. Possible mechanisms proposed are actions of CBD and omega 3 on CB1, TRVP and 5HT receptors in reducing anxiety and their antioxidant/anti-inflammatory actions in mitigating the neuro-inflammatory effect of HFD and immune hyperstimulation of E. coli via the gutbrain-axis.
