- The reduction of Bifidobacteria, the main producers of lactic acid capable of suppressing the growth of pathogenic bacteria, leads to an alteration of the immunitary system.
- Dietary fiber > competitive advantage to Bifidobacteria
- Loss of Bifidobacterium early in life has been associated with increased risk of developing autoimmunity, as seen in a birth cohort in Finland and atopic wheeze in another cohort in rural Ecuador.
