ABSTRACT
Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) have been associated with several inflammatory conditions, including inflammatory bowel diseases (IBDs), and found to have an impact on gut microbiota. In fact, some randomized controlled studies suggest benefits to IBD patients, but others do not. Our aim was to review recent evidence on the effects of omega-3 on IBD and establish the contribution of the gut microbiome. Omega-3 mediate anti-inflammatory effects in IBD through various mechanisms, including suppression of NLR family pyrin domain-containing 3 (NLRP3) inflammasome, Toll-like receptor-4 (TLR4), and nucleotide-binding oligomerization domain 2 (NOD2) signaling; this results in the repression of the nuclear factor-kappa B (Nf-kB) pathway and the secretion of pro-inflammatory cytokines. Omega-3 can also affect gut microbiota and revert the bacterial community to patterns associated with healthy status by increasing short-chain fatty acid (SCFA)-producing bacteria and enhancing the mucosal gut barrier, thus promoting homeostasis. The combination of these immunoregulatory effects and anti-inflammation properties with the promotion of a balanced gut microbiome environment could suggest that omega-3 might benefit IBD patients. Considering the microbiota of IBD patients while using omega-3 might predict and improve omega-3 effectiveness. Combining omega-3 with bacteria-altering therapy, such as probiotics and fecal microbiota transplantation, may further enhance its efficacy; however, further studies are required to elucidate mechanisms and potential preventive or treatment roles of omega-3 in IBD.
