Abstract:
The health benefits of tuna oil, which is different from the fish oil commonly studied, and its higher docosahexaenoic acid (DHA) content, have attracted much scientific attention in recent years. In this study, prepared tuna oil with higher DHA (HDTO) content was employed. It was the first to integrate microbiome and metabolome from a dose‐effect perspective to investigate the influence of HDTO on gut dysbiosis and metabolic disorders in diet‐induced obese mice. RESULTS Higher DHA tuna oil was effective in reversing high‐fat‐diet‐induced metabolic disorders and altering the composition and function of gut microbiota, but these effects were not uniformly dose dependent. The flora and metabolites that were targeted to be regulated by HDTO supplementation were Prevotella , Bifidobacterium , Olsenella , glycine, l ‐aspartate, l ‐serine, l ‐valine, l ‐isoleucine, l ‐threonine, l ‐tyrosine, glyceric acid, glycerol, butanedioic acid, and citrate, respectively. Functional pathway analysis revealed that alterations in these metabolic biomarkers were associated with six main metabolic pathways: glycine, serine, and threonine metabolism; glycerolipid metabolism; glyoxylate and dicarboxylate metabolism; alanine, aspartate, and glutamate metabolism; aminoacyl‐tRNA biosynthesis, and the citrate cycle (TCA cycle). CONCLUSION Various doses of HDTO could attenuate endogenous disorders to varying degrees by regulating multiple perturbed pathways to the normal state. This explicit dose research for novel fish oil with high‐DHA will provide a valuable reference for those seeking to exploit its clinical therapeutic potential. © 2022 Society of Chemical Industry.
