Here’s a recent podcast, episode #2, of This Week in Microbiology on how gut bacteria control body weight and metabolic activity. The recent study discussed in the podcast takes a “Systems Biology” approach to researching gut bacteria’s positive impact and colony succession over time, on baby, child and adult mammal liver functions in particular, but raises questions about a “probiotic” (vs antibiotic) approach to human health.
My last post pointed out the very interesting research going on into microbes and human health and how some of it seems to parallel a”probiotic” microbiological farming approach. The paradigm that microbes are essentially “all bad” and should be wiped out of the human body and our farm fields for human and agricultural plant health is giving way to another view: there are good guy microbes and we need to partner with them in our bodies and in our soils. Also, the “Systems Biology” approach discussed in the podcast is a relatively new way to approach researching the complex world of microbes but it is opening up how microbial communities change over time (succession) and have many beneficial colony and host interactions.
