Ameliorating the Adverse Effects of Excess Propionic Acid

I am officially declaring this Biome Buzz’ first annual Propionic Acid Week! (Unfortunately, this is not a cause for celebration.) If you remember, propionic acid (PPA) is a short-chain fatty acid produced by gut bacteria.  Ordinarily, PPA , like the other SCFAs, is great…

Is There Any Doubt Left that Propionic Acid is a Cause of Autism? Apparently not

I first started to write about autism and propionic acid (PPA) not long after creating this blog, back in the fall of 2016.  In January 2017, I described to you some of the work of Dr. Derrick MacFabe, which as particularly fascinated me for…

The Two Sides of Bacteroides fragilis

Back in May, 2018, I wrote about Bacteriodes fragilis (B. fragilis), a species of bacteria some strains of which are toxic, some of which are highly beneficial.  The main thrust of that post was about how our immune system, when functioning properly, can recognize…

Neurodegnerative and Neuropsychiatric Disorders: Prime Targets for Helminths

Within just a few weeks of each other, two papers have been published looking at the potential of using helminths to treat neurological conditions.  Not surprisingly, both focus on the powerful anti-inflammatory effect of helminths. (For those of you new to helminths:  these are…

Autism and Clostridia: Mounting Evidence of a Connection

As you know, I’ve been following the research of Dr. Derrick MacFabe for well over a decade now.  I’ve described it before on this blog, several times, including this first post 2 ½ years ago – to which, if you remember, Dr. MacFabe was…

Constipation, Dysbiosis, Autism and a Prebiotic: A New Clinical Trial

The single most common gastrointestinal (GI) complaint I hear as a nutritionist, by a long way, is constipation…and the single best piece of advice I give my clients is “drink more water.”  It never ceases to amaze me how dehydrated most people are.  Invariably,…

Fibromyalgia: Yet Another Biome Related Illness

I’ve written before about recent findings that alterations in the gut bacteria are associated with chronic fatigue syndrome (CFS), which is closely related to fibromyalgia.  For those of you unfamiliar, the symptoms of fibromyalgia include wide spread body pain, fatigue, impaired sleep, potentially cognitive…

Stressed? Spend Time Outdoors to Get Your Mycobacterium vaccae

For the last couple of years, I’ve followed the research of a team out of the University of Colorado, who have been looking into treating stress and anxiety by using microbiotic organisms, and have even been exploring the idea of creating a vaccine to…

Two New Articles on Parkinson’s

Two more recent article provide yet more evidence linking gut inflammation to the development of Parkinson’s disease…which my regular readers know, is another of my particular interests, as I have 3 friends already suffering from it. The first article describes research at the University…

The Microbiome and Mental Illness: An Old Story that is Too Far From its Happy Ending

I just finished reading an article from 2018 on mental health and the microbiome that describes some of where we are now, knowledge-wise, and where we need to be before psychobiotics become a treatment norm.[i]  There were multiple pieces of information in it which…
