Human Microbiome

Complex community of microorganisms living in the human intestine.

Definition

The collective microorganisms (bacteria, viruses, fungi, and archaea) inhabiting the human gastrointestinal tract.

How it works

The microbiome is a living ecosystem that cohabits with our intestinal cells and plays pivotal roles in health. These microorganisms ferment dietary fibers, synthesize essential vitamins, and protect against pathogens. The microbiome constantly communicates with our immune system and influences even our neurological functions via the gut-brain axis. Its balance and diversity are significant markers of overall health.

Role

Ensures digestion, synthesizes vitamins, strengthens immunity, and influences metabolic and mental health.

Examples

  • Lactobacillus
  • Bifidobacterium
  • Faecalibacterium prausnitzii
  • Akkermansia muciniphila

Recommendations

Encourage a high-fiber diet, consume natural fermented foods, avoid unnecessary antibiotics, and maintain good digestive hygiene. A healthy microbiome is gradually built up by consistent food choices.

Key takeaway

The microbiome is an invisible yet fundamental organ for digestive, immune, and overall health.
