What You Eat: the Main Factor in Determining Your Microbiota

A new study out of Washington University in St. Louis shows, yet again, that even species matters less than what you eat and your lifestyle in determining the composition of your gut bacteria.[i] These researchers analyzed the fecal microbiota a of 18 wild chimpanzees…

Since Things Already Stink in This COVID-Ridden World, We Might as Well Talk Gas

I posted this story up on Facebook a few weeks ago, but have decided – since the issue is so endemic – it’s worth a blog post, for those of you who missed it.  When I was working as a nutritionist, the single most…

The Maternal Microbiome and Risk for Food Allergy in Babies

The big (biome) buzz of the last couple of weeks:  research just published out of Australia shows that the presence of a certain species of gut bacteria, Prevotella copri, in pregnant women protects babies from developing food allergies  – at least within their first…

A Metabolite Direct Link Between the Gut and the Brain: Think Autism, Parkinson’s, etc….

Today’s post describes what may be a critical finding in defining at least one mechanism whereby gut microbes directly affect the brain.  Those interested in developmental disorders, like autism; Parkinson’s; Alzheimer’s; chronic fatigue; etc. should pay particular attention as, according this article, this information…

Response to Prebiotics Depends on Your Existing Gut Bacteria

This is a small, but I thought really interesting, study and I guess I’m not alone in finding it significant:  it was published in a premier medical journal, Gut.[i]  It’s a great illustration of the complexity of gut biome optimization because of the individuality…

Inflammatory Arthritis and the Gut

I’ve been keeping an eye out for anything new and interesting in the realm of the biome and arthritis – any kind of arthritis.  Following are some highlights from a recent article on the two way communication between the gut immune system and the…

Parkison’s and the Gut: An Update

I haven’t given you a Parkinson’s-and-the-biome update in several months now, and as yesterday I read a great review of the current status of our knowledge on the connection between the two, I figured it was time.[i] I am sure that most of you…

Inflammatory Bowel Disease, the Microbiome and…(ahhhh!) Mango

My regular readers know that I am always on the lookout for “things you can do now,” and that I get very excited when I find something that actually makes sense, even if it’s not entirely proven or the mechanism of action fully understood. …

Bile Acids, Inflammatory Bowel Disease, and the Microbiome: A Rapidly Developing Story

Back in January, I wrote about how bile acids are regulators of inflammation and thus, when dysregulated (either too high or too low), this dysregulation can lead to disease.  Bile is produced by the liver and excreted into the intestines to digest fat.  Gut…

Babies, Anxiety and the Gut Biome

Remember last Thursday, when I wrote about the relationship of the gut bacteria to the structure and function of the brain?    I mentioned in that post that, “In Western populations, Bacteroides and Prevotella species tend to dominate, with the former outnumbering the latter…
