It is my current understanding that a high fat diet increases endotoxemia by affecting the bowel bacterial composition, specifically by reducing bifidobacteria. I think it is the bifidobacteria which help maintain intestinal integrity.

Animal fat may play a profound role in the pathogenesis of after-meal inflammation by increasing the absorption of the endotoxins, since endotoxin has a strong affinity for the saturated fat transport system (chylomicrons lipoproteins that transport dietary long chain saturated fatty acids through the gut wall and into the blood stream). So animal fat may play a role in boosting endotoxin absorption, but the primary reason all those studies show increased inflammation from animal foods, but not from unfermented plant foods, may be the load of dead bacteria, which release endotoxins that are absorbed into our system leading to the endotoxemic inflammation we see after meat, egg, and dairy consumption.

>Very interesting. As you indicated, this is pretty compelling evidence that a high fat meal results in facilitated 'transportation' of endotoxins from the bowel into the bloodstream, causing inflammation.
Have you read the research showing that increasing bifidobacterial levels reverse endotoxemia caused by high fat diet? This has been shown in two separate studies. I wonder how this fits in with the above?
