Faecalibacterium prausnitzii is one of the most abundant bacteria in the human gut flora and plays a crucial role in maintaining our health. This gram-positive, anaerobic bacterium is known for its anti-inflammatory properties and contributes to the integrity of the intestinal barrier. Recent research suggests that an imbalance in the presence of F. prausnitzii may be linked to several skin and immune diseases including psoriasis.
Faecalibacterium prausnitzii and the gut-skin axis
The gut-skin axis refers to the complex interaction between the gut microbiota and skin health. Healthy gut flora supports the immune system and helps prevent inflammatory responses that can damage the skin. F. prausnitzii produces butyrate, a short-chain fatty acid with potent anti-inflammatory effects, which helps maintain healthy skin.
Influence on skin diseases
Studies have shown that a decrease in F. prausnitzii can be associated with skin diseases such as eczema and psoriasis. In patients with atopic eczema, a lower concentration of this bacterium has been observed in the gut, suggesting that restoring the balance of the gut microbiota could be a potential therapy. Similarly, a reduced presence of F. prausnitzii may contribute to the development or worsening of psoriasis by promoting systemic inflammation.
Influence on immune diseases
In addition to skin diseases, F. prausnitzii is also involved in the modulation of the immune system. Reduced presence of this bacterium has been linked to inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. Restoring healthy levels of F. prausnitzii may therefore be a therapeutic strategy to reduce inflammatory responses and restore immune balance.
To increase the number of Faecalibacterium prausnitzii in your body, you can use the following strategies:
1. High Fiber Diet
F. prausnitzii feeds primarily on soluble fiber. Eating fiber-rich foods can help this bacteria grow. Consider:
- Prebiotic foods such as garlic, onions, leeks, asparagus, bananas and oats.
- Legumes , such as lentils, chickpeas and beans.
- Whole grains , such as oats and barley.
2. Short-chain fatty acids (SCFAs)
This bacteria produces butyrate, a short-chain fatty acid with anti-inflammatory properties. By eating foods that contribute to the production of SCFAs, you can support their growth:
- Fermented foods such as sauerkraut, kimchi and kefir.
- Resistant starches , found in cooled cooked potatoes and rice.
3. Probiotics and Prebiotics
Although F. prausnitzii itself is not available as a probiotic, other probiotic bacteria that support gut flora may help indirectly. Consider:
- Bifidobacteria and Lactobacilli from probiotic supplements or fermented dairy products.
- Prebiotic supplements such as inulin or fructo-oligosaccharides (FOS) to promote the growth of beneficial bacteria.
4. Avoiding Intestinal Flora Disruption
- Limit the use of antibiotics unless strictly necessary, as they can disrupt the intestinal flora.
- Avoid ultra-processed foods with artificial sweeteners, preservatives and emulsifiers that can harm gut health.
5. Healthy Lifestyle
- Regular exercise supports healthy intestinal flora.
- Stress management , such as meditation and adequate sleep, helps regulate the immune system and gut health.

Conclusion
Faecalibacterium prausnitzii plays an essential role in maintaining both gut and skin health and regulating the immune system. Promoting a healthy population of this bacteria through diet, probiotics or prebiotics may be a promising approach for the prevention and treatment of various skin and immune diseases
