The prebiotic inulin affects virulence factor expression in Candida albicans.

Prebiotic Fiber
Dandelion roots you pull as lawn weeds are loaded with inulin — the same plant fiber now shown to dial down a common gut fungus's ability to shift into its infectious, thread-like form.
Inulin is a natural fiber packed into everyday garden plants like chicory, Jerusalem artichoke, garlic, and dandelion. Scientists discovered that when the gut fungus Candida albicans encounters this fiber, it stops growing in its more dangerous, thread-like mode and becomes easier for the immune system to handle. This hints that simply eating more of these inulin-rich plants could help keep Candida from causing trouble.
Key Findings
Inulin blocked Candida albicans from switching into its hyphal (thread-like, invasive) form — the growth mode directly linked to active infection
Inulin reduced exposure of immune-triggering molecules on the fungal cell wall (β-glucan and chitin), altering how human immune cells detected and responded to the fungus
Inulin measurably attenuated C. albicans virulence in a live invertebrate infection model, providing whole-organism evidence of a protective effect
chevron_right Technical Summary
A natural plant fiber called inulin changes how the gut fungus Candida albicans behaves — suppressing its aggressive, invasive growth form and making it easier for the immune system to control. The findings suggest that diets rich in inulin-containing plants may lower the risk of Candida infections in healthy people.
