Dr. Manuele Biazzo, a nutritional biologist, Scientific Director of The BioArte and founder of the Centro Toscano Microbiota, was interviewed by IO Donna, the wellness magazine of Corriere della Sera, to shed light on one of the most discussed topics in modern health: the microbiota.
In the article, Dr. Biazzo analyzes the 5 most common myths about the gut microbiota in clear, scientific language and explains why it is essential to adopt a personalized, evidence-based approach.
Myth 1 – “We have 10 times more bacteria than human cells”
Dr. Biazzo clarifies that science has now moved beyond this figure: the real ratio is approximately 39 trillion bacteria to 30 trillion cells, a more precise balance that is useful for understanding the role of the microbiota.
Myth 2 – “More fiber is always good”
As Dr. Biazzo explains, some fibers (especially fermentable ones) can worsen symptoms in cases of dysbiosis or irritable bowel syndrome. Only a microbiota analysis allows for an understanding of which fibers are truly suitable.
Myth 3 – “All probiotics work”
According to Dr. Biazzo, every probiotic strain has a specific function. Taking one at random can be useless or counterproductive if the microbiota is already in imbalance.
Myth 4 – “Detox products cleanse the gut”
Dr. Biazzo emphasizes that the body already has powerful detoxification mechanisms: the liver, kidneys, and microbiota work every day to maintain balance. Rather than “cleansing,” one needs to modulate.
Myth 5 – “The microbiota does not change”
Dr. Biazzo reminds us that the microbiota is extremely dynamic and changes continuously based on diet, stress, medications, and lifestyle. This makes it modulable with targeted strategies and objective data.
Dr. Biazzo’s vision: data, tests, and a tailored approach
The message from Dr. Manuele Biazzo is clear: the microbiota should not be managed with passing fads or generic products, but analyzed, interpreted, and guided with a scientific and personalized approach.
