My Bacteria - Your Microbiome. Your Health.

We like to talk about the bright side of the microbiome. Digestion, protection, the immune system, metabolism, and all the remarkable abilities our bacteria give us. But symbiosis is not free. Our body lives in close proximity to trillions of microorganisms. This closeness is an advantage, but it demands control. Barriers must be maintained, immune responses must be regulated, microbial signals mu...

The human body is not a sterile machine. It is an ecosystem. In this episode, we explore an idea that is quietly transforming how we think about health, immunity, stress, and even human identity itself: we do not live alone. Trillions of microorganisms accompany us throughout our lives, shaping digestion, metabolism, immune function, resilience, and perhaps even aspects of mood and behavior. We ta...

We often think that a child’s microbiome is shaped primarily by the mother and family. A new study in Nature now shows that other children also have a massive influence on the gut microbiome. Researchers analyzed more than 1,000 stool samples from Italian daycare centers and were able to track, at the strain level, how bacterial lineages are transmitted between children. Measurable microbial netwo...

Colon cleanses promise a reset. Clear the gut, remove toxins, start fresh. But the gut doesn’t work like that. It’s not a passive tube. It’s a complex system of mucus, microbes, and barrier function. And when you intervene mechanically, you don’t “clean” it. You disrupt it. In this episode, we break down what actually happens during colon cleansing. How procedures like colon hydrotherapy and enema...

Your gut isn’t a wellness temple. It’s a high-efficiency cauldron. Forget the "good vs. bad" bacteria myth.

Stop guessing, start managing. We’re moving beyond moralizing your diet and focusing on the three currencies that actu...

“You have dysbiosis.” A medical-sounding phrase that quickly comes across as a clear diagnosis. But what does dysbiosis actually mean in scientific terms? The term is used frequently in doctors' offices, literature, and public discourse. At the same time, it often remains unclear what it specifically refers to. This episode provides some clarity: What is a “healthy” microbiome anyway? Is there a u...

A spoonful of fresh yogurt or a forkful of sauerkraut, and a journey reminiscent of an epic drama begins inside us. But while we are still enjoying the taste, billions of microorganisms are already heading for what is probably the most dangerous barrier in evolution: the stomach.

Microplastics have quietly become part of our bodies, found in water, food, blood, and even the brain. But their most profound impact may lie within the gut. Tiny plastic particles interact with the intestinal microbiome, disrupting its delicate balance and triggering inflammation, oxidative stress, and immune reactions. This episode explores how microplastics alter the gut microbiota, how these c...

Is your microbiome predetermined, or can you shape it through diet and lifestyle? Fiber, probiotics, antibiotics, or even stool transplants – there are many ways to shape the microbiome. But which of these actually work, which are only short-term solutions, and where does the resilience of our intestinal flora reach its limits? This episode highlights the latest findings on the intestinal microbio...
