Gut Bacteria in Children with Autism Are Different

There is a distinct connection between changes in gut bacteria and autism, a topic I have written and blogged about before. A recent study presented at the annual meeting of the American Society for Microbiology found that children with autism spectrum disorders (ASDs) have different concentrations of bacterial metabolites, or chemicals produced by bacteria, in their stool when compared to…

Sucralose is Not the Harmless Sweetener It’s Made Out to Be

If you are avoiding sugar (which is a good thing!), yet you substitute with sucralose—the generic name for the stuff in the yellow packets—you might want to know that researchers are concerned about the safety of this artificial sweetener based on many of its biological effects in the body. Researchers from the National Institutes of Health recently published a report…

Gut Microbes and L-carnitine—Good or Bad for You?

A recent study has got many people talking about the potential benefits—or detriments, depending which side you’re on—of L-carnitine for heart health. The study, by Cleveland Clinic and published in Nature Medicine, found a link between increased blood levels of TMAO (trimethylamine N-oxide, a metabolite of L-carnitine produced in the gut by certain bacteria) and an increased risk of cardiovascular…

Breast Milk—And Not Infant Formula—Promotes Beneficial Biofilm

Bacteria in the digestive tract exist in two main ways—First, within a polysaccharide matrix known as a biofilm that adheres to the intestinal lining or to digestive contents, or second, floating in a non-adherent manner as single cells. In the natural world, 99 percent of all bacteria exist as biofilms,1 so the study of biofilms in the gut is proving…

Cracking the Gut Microbial Code: Are We There Yet?

“In the future, when you walk into a doctor’s surgery or hospital, you could be asked not just about your allergies and blood group, but also about your gut type.” This is a quote from ScienceDaily (Apr. 21, 2011) referring to a recent article in Nature Magazine. The study, published in Nature, also uncovers microbial genetic markers that are related…

Big Pharma Learns from Natural Medicine – Again!

I came across an interesting article recently in the Journal of Gastroenterology.  The title caught my eye – “Gut Microbes: From Bugs to Drugs”.  I have to share with you a few comments from this article.  Now, this is a mainstream gastroenterology journal.  The article covers some ideas about how probiotics, or pharmabiotics (the term they use that includes probiotic…
