Consuming more fiber, commonly found in whole grains, vegetables, and fruits, may help defend against harmful bacteria in the gut.

A recent study published in Nature Microbiology reveals individuals with high levels of the beneficial bacteria Faecalibacterium are more likely to have lower levels of harmful bacteria like E. coli. The research, which analyzed gut microbiome samples from over 12,000 people across 45 countries, highlights the potential health benefits of this particular microorganism.

The researchers also discovered that samples rich in Faecalibacterium contained elevated levels of beneficial compounds known as short-chain fatty acids, which are produced when fiber is broken down. Studies have shown that lower levels of this bacteria are associated with inflammatory bowel and gastrointestinal disorders.
