Stressed? Depressed? Theres a Psychobiotic for That

Yesterday morning a story made its way through the British press about a probiotic, newly available commercially, which, in a 2016 clinical trial, successfully alleviated stress, increased feelings of happiness and boosted memory.  The probiotic, Zenflore, is being called the first commercially available “psychobiotic”: …

Stress and Our Missing Old Friends

Yesterday I devoted several hours to reading a fascinating article on the connection between stress and the microbiome.[i]  The conclusion:  the lack of exposure to our “old friends” (those commensal organisms with which humans co-evolved) has caused immune dysregulation, leading to a greater susceptibility…

Leaky Gut and Leaky Brains…and Disease

If you remember, my last post was a quick update on what we currently know about the microbiome-depression link, and I mention leaky gut with a promise to write more about it this week.  Toward that end, on Friday evening, I read an article…

Depression and the Microbiome: A Brief Update

A few days ago, the website Psychiatry Advisor, had a very nice review article[i] of our current understanding of probiotics’ effects on depression. I’ve written about this before, obviously, but want to always keep you updated on all the latest.  Besides, this is also…

Stress, Inflammation and the Human Biome

Today’s post hits a little too close to home.  I just read about a fascinating study done at Ohio State University that highlights something about which I am only too personally aware:  the effects of stress on health.[i] In this particular case, researchers were…

Stress and Autoimmune Disease: A Relationship that is Becoming More Defined

One of the big medical news stories of the week was the results of 30 years’ worth of research published in JAMA (the Journal of the American Medical Association), examining the connection between stress and the development of autoimmune disease.[i]  Over 1 million people…

A Probiotic Vaccine Against Anxiety and PTSD?!

In May 2017 I wrote about some really exciting research into the probiotic bacteria Lactobacillus reuteri (which is derived from human breast milk) in both PTSD and autism.  If you remember, I mentioned that a clinical trial would be conducted on 40 veterans with…

Healthy Aging and the Microbiome

I really liked this summary article on Medical Net about the bacterial microbiome through the aging process.[i]  It is certainly worth a post, as all of us are getting older every day!  🙂 Highlights: Multiple factors can lead to dysbiosis as we age: Poor…

The Gut, the Brain and Mood

There have been multiple articles this week looking at the relationship of our microbes to mood.  I thought this research out of Oxford University[i] was particularly interesting in that, it looked at that relationship from an evolutionary point-of-view. It’s accepted as fact now that…

Yet More New (and Scary) Research on Maternal Immune Activation

An old doctor friend of mine used to always say, “Inflammation is inflammation.”  Truer words were never spoken.  Whether inflammation manifests as swelling because you just broke your leg or an autoimmune disease, ultimately, it’s all the same.  The only difference is, how long…

Some Research High Points of 2017

Well, it’s time yet again for the big New Year’s countdown of my  favorite biome research stories of the year!!! January:  The Specific Carbohydrate Diet study at Seattle Children’s Hospital on 10 pediatric patients with Crohn’s disease.  After only 12 weeks, 8 of the…

Holiday Time, Depression and the Microbiome: Musings

Researchers into multiple sclerosis at Mount Sinai Hospital in New York City were looking at how antibiotics affect the myelin sheath and neuron damage when they noticed that the mice they were using were exhibiting behavioral changes, in terms of depressive symptoms.  Upon further…
