Allobaculum has also shown to be negatively correlated with ALT, AST, and TNFα resulting in a reduced hepatic steatosis suggesting protection against inflammation and oxidative stress through SCFA.90 In the current study, an increase of propionate concentration in caecal content was only found in HF-ω3 mice, in which hepatic steatosis was totally inhibited. Here, TNF is linked to Hepatic steatosis.
