Gut & Microbiome for Immunity

Strength Begins in the Gut

Why it matters:
Around 70% of your immune system is located in the gut. If the gut microbiome is imbalanced, immunity weakens — making you more prone to infections, inflammation, and even allergies. A healthy gut means stronger defenses and better overall well-being.

How it works:

  • Probiotics → beneficial bacteria that strengthen gut lining and immune signaling.
  • Prebiotics → fibers that feed good bacteria, keeping them active and diverse.
  • Glutamine → an amino acid that repairs the intestinal wall, preventing “leaky gut.”
  • Fiber → fuels beneficial bacteria and supports regular elimination of toxins.
  • Polyphenols → plant compounds that reduce gut inflammation and protect microbes.

Foods that help:

  • Yogurt, kefir, sauerkraut, kimchi → probiotics
  • Onions, garlic, bananas, asparagus → prebiotics
  • Legumes, whole grains, flaxseed → fiber
  • Berries, green tea, olive oil → polyphenols
  • Bone broth → glutamine for gut lining repair

Lifestyle tip:

Antibiotics, stress, and highly processed foods disrupt the gut microbiome. Restoring balance with fermented foods and fiber is key to long-term immune health.
