Probiotic Foods: Why and What to Eat
Your gut hosts 100 trillion bacteria — more than your body cells. This microbiome regulates digestion, immunity, mood (90% of serotonin made in gut), and even weight. Probiotic foods feed this ecosystem.
Best Sources
Kefir (30+ strains, richest probiotic drink). Yogurt (Lactobacillus, Streptococcus). Sauerkraut (homemade). Kimchi. Tempeh. Miso. Kombucha. Look for 'live cultures' on label.
Prebiotics: Fuel for Probiotics
Garlic, onion, leek, asparagus, banana (less ripe), oats, lentils, beans, apple. Daily 5-10 g prebiotic fiber.
Practical Integration
Morning kefir or yogurt + fruit. Sauerkraut on salads. Tempeh stir-fries 1-2× week. Start small — gas/bloating first 1-2 weeks while gut adapts.
