Bifidobacterium

Definition

A genus of beneficial anaerobic bacteria that ferment dietary fibers and produce lactic acid and acetic acid. Bifidobacteria dominate the infant microbiome.

How it works

Bifidobacteria are strict anaerobes that primarily produce acetic acid by fermenting fibers, particularly fructo-oligosaccharides and inulin. They significantly reinforce the intestinal barrier, produce B vitamins, and reduce toxic compounds.

Role

Produces short-chain fatty acids, reinforces immunity, and stabilizes the microbiome.

Examples

• Bifidobacterium longum, Bifidobacterium infantis, Bifidobacterium breve, Bifidobacterium adolescentis

Recommendations

Consume foods containing inulin and FOS (onions, garlic, artichokes, underripe bananas) to nourish Bifidobacteria. Specific probiotic supplementation may be useful in cases of dysbiosis.

Key takeaway

Bifidobacteria are essential for a healthy microbiome and optimal immunity.
