A healthy gut is the key to a strong immune system!

Our gut is one of the most important systems that directly affect the health of the entire body. In addition to its digestive function, it serves as the true "control center" of immunity. Modern research shows that our gut bacteria influence the immune system, making it essential to maintain a balanced microbiome. One effective way to support gut health is by consuming Auricularia auricula, a mushroom rich in polysaccharides, which has long been used in traditional Eastern medicine.

A study conducted by scientists in China was published in 2020 in the journal Frontiers in Immunology. The aim of the study was to investigate the impact of polysaccharides from Auricularia on the immune system and gut microbiota of mice with suppressed immunity. The study found that Auricularia polysaccharides (AAP) significantly improve immune system function, restore gut microbiota balance, and support the gut barrier function.

The effects of Auricularia on gut bacteria:

  • Stimulation of beneficial bacteria growth: Polysaccharides in Auricularia act as natural prebiotics. They serve as a food source for beneficial bacteria such as Bifidobacterium and Lactobacillus, helping to maintain the balance of the gut microbiome. Thanks to Auricularia polysaccharides, these bacteria multiply actively, reducing the number of harmful microorganisms and strengthening the immune system.
  • Increased production of short-chain fatty acids (SCFAs): Gut bacteria, such as Faecalibacterium prausnitzii and Roseburia, can ferment polysaccharides from Auricularia, producing important short-chain fatty acids (SCFAs), including butyrate, acetate, and propionate. These acids not only support gut mucosal health but also have powerful anti-inflammatory properties. Butyrate, in particular, helps strengthen the gut barrier and reduce inflammation.
  • Anti-inflammatory effect: Auricularia polysaccharides are known for their antioxidant and anti-inflammatory properties. This helps reduce inflammation in the gut, which is crucial for maintaining balance between beneficial and pathogenic bacteria. For instance, polysaccharides reduce levels of harmful bacteria such as pathogenic strains of Escherichia coli and some members of the Proteobacteria family, which often cause inflammation and dysbiosis.
  • Improvement of gut barrier function: One of the most important effects of Auricularia is its ability to maintain and restore gut barrier function. Auricularia increases levels of proteins like claudin-1, occludin, and ZO-1, which are responsible for cell junctions in the intestinal epithelium. This is important for preventing pathogens from entering and preserving the integrity of the mucosal layer. Additionally, Auricularia stimulates the growth of the beneficial bacterium Akkermansia muciniphila, which helps maintain the integrity of the mucosa and promotes overall gut health.

In addition to its positive effect on gut microbiota, Auricularia auricula enhances the immune function of the body. Auricularia polysaccharides significantly increase levels of important immune cytokines: IFN-γ — helps the body fight viral infections; IL-2 — promotes the growth and activation of T-cells, which are responsible for destroying infected cells; IL-4 and IL-10 — regulate the immune system and reduce inflammation; TNF-α — important for fighting tumors and infections.

Compared to the control group, mice that received Auricularia polysaccharides showed:

  • A 30-40% increase in key cytokine levels.
  • An improvement in the condition of immune organs (thymus and spleen) by almost 25%.
  • The balance of gut bacteria returned to normal levels, contributing to the restoration of digestive processes.

One of the important indicators of gut health is the ratio of Firmicutes to Bacteroidetes bacteria. In dysbiosis, caused by stress, poor diet, or medication, the number of Firmicutes increases, which may contribute to inflammation. Auricularia polysaccharides help reduce Firmicutes levels and restore balance by increasing the number of Bacteroidetes. Moreover, there was a reduction in harmful bacteria such as Helicobacter and Escherichia-Shigella, which often trigger inflammatory processes.

After consuming Auricularia polysaccharides, the number of beneficial bacteria such as Bacteroides, Lactobacillus, Alloprevotella, and Blautia significantly increased, improving the gut microbiome and overall health.

Studies confirmed that Auricularia auricula supports gut health, improves the immune system, reduces inflammation, and restores microbiota balance.

Consuming Auricularia auricula will benefit those seeking to improve their overall health, as well as individuals with immune or digestive issues.
