    High-fiber diets reshape gut microbiota composition and enhance short-chain fatty acid production, influencing immune responses.

  • 2

    Short-chain fatty acids promote regulatory T-cell expansion and restore Th1/Th2 balance, alleviating airway inflammation in asthma.

  • 3

    The gut-lung axis mediates communication between the gastrointestinal tract and respiratory system, impacting pulmonary immune responses.

  • 4

    High-fiber diets increase beneficial bacteria such as Lactobacillus and Bifidobacterium, contributing to gut microbiota homeostasis.

  • 5

    Further investigation is needed to understand the long-term efficacy of high-fiber diets on asthma across diverse populations.
