Angela the link is Re Richard the 111, I believe that brain inflammation could also trigger depression. I never heard the link between fat and brain inflammation. I read once that brain inflamation can be a side effect of certatin medications. It would be interesting to read the article.
Thanks, Maleth....I was really pressed for time today, so I got sloppy.
Here is the actual link. I've also fixed the original post.

"A new study published in the current issue of
Biological Psychiatry raises the possibility that a high-fat diet produces changes in health and behavior, in part, by changing the mix of bacteria in the gut, also known as the gut microbiome."
"Non-obese adult mice were conventionally housed and maintained on a normal diet, but received a transplant of gut microbiota from donor mice that had been fed either a high-fat diet or control diet. The recipient mice were then evaluated for changes in behavior and cognition. The animals who received the microbiota shaped by a high-fat diet showed multiple disruptions in behavior, including increased anxiety, impaired memory, and repetitive behaviors. Further, they showed many detrimental effects in the body, including increased intestinal permeability and markers of inflammation. Signs of inflammation in the brain were also evident and may have contributed to the behavioral changes."
"Indeed, these findings provide evidence that diet-induced changes to the gut microbiome are sufficient to alter brain function even in the absence of obesity. This is consistent with prior research, which has established an association between numerous psychiatric conditions and gastrointestinal symptoms, but unfortunately, the mechanisms by which gut microbiota affect behavior are still not well understood."
They've known about the correlations between such things for a long time. Just as one example, people suffering from certain kinds of auto-immune disorders, which involve high and measurable levels of inflammation, show psychological effects which abate when inflammation levels decrease.
A friend of mine sent me the following link a while ago. There may be something to it. There are links to research studies...
