New Delhi, Jan 13: Your gut microbiome plays a crucial role in defending against infections, but it needs proper nourishment to function effectively. A diet rich in fibre especially from vegetables, legumes, and whole grains promotes the growth of beneficial bacteria, creating a healthier gut environment.

The gut is home to trillions of microorganisms, including bacteria, viruses, and fungi. Among these are Enterobacteriaceae, a family of bacteria that includes dangerous pathogens like Klebsiella pneumoniae, E coli, and Shigella. When in balance, Enterobacteriaceae cause no harm. However, factors like poor diet and inflammation can trigger their overgrowth, leading to potentially life-threatening infections. This is especially concerning as antibiotic resistance continues to rise.

Recent research by the University of Cambridge highlights the importance of a balanced gut microbiome. The study, which analysed over 12,000 stool samples from 45 countries using cutting-edge AI tools, reveals that a healthy microbiome can predict your resistance to infections caused by harmful bacteria like Enterobacteriaceae.

The study identified 135 protective bacteria species that help fight these pathogens. Faecalibacterium, one of the most notable, breaks down dietary fibre to produce short-chain fatty acids (SCFAs). These acids create an unfriendly environment for harmful bacteria, lowering infection risks.

To support your gut microbiome, focus on a fibre-rich diet that encourages the growth of these protective species. While probiotics may offer some benefits, they aren’t as effective as a diet that naturally supports your gut’s defences.

As antibiotic resistance grows, strengthening your microbiome through diet could become an essential strategy in preventing infections like pneumonia, meningitis, and bloodstream infections. By nourishing beneficial bacteria with fibre, you can crowd out harmful pathogens, reducing the risk of serious infections.

The study also revealed new insights into the interaction between gut microbes, showing that 172 species of gut bacteria can coexist with harmful Enterobacteriaceae despite competing for the same nutrients. This challenges the idea that simply introducing probiotics can outcompete harmful bacteria. Instead, fostering a healthy gut environment through diet—specifically fibre remains the best way to stay infection free.
