>"Indeed, high blood levels of lipopolysaccharides and certain short-chain fatty acids (acetate and valerate) were associated with both large amyloid deposits in the brain.
Any indications which bacteria produces these amyloids?
This discovery paves the way for potentially highly innovative protective strategies -- through the administration of a bacterial cocktail, for example, or of pre-biotics to feed the "good" bacteria in our intestine.
I wouldn't be surprised if there isn't a one sized fits all here. Probably having a big diverse population is better than shooting yourself with a few strains, as we get older we have less diversity of gut bacteria and interesting the younger have the opposite.
I'm unsure how? we're generally consuming the same foods, if not better quality comparatively to younger people?
I heavily doubt that's the main reason for this difference, but old people diets are a healthcare trope for a reason.
Same thing with SCFAs, they are normally part of the metabolic cycle of many bacteria. Tracking down one of them is nearly impossible from something as complex as the gut microbiome.
