🦠 Probiotics and Fermented Foods
Evidence-Based Benefits
- Antibiotic-associated diarrhea: Strong evidence for prevention

Food Sources
| Food | Probiotic Benefit | How to Include |
|---|---|---|
| Yogurt (live cultures) | Lactobacillus, Bifidobacterium | 1 cup daily; check for "live cultures" |
| Kefir | Multiple strains, highly diverse | 1 cup daily; more potent than yogurt |
| Sauerkraut (unpasteurized) | Lactobacillus | 2-3 tablespoons with meals |
| Kimchi | Lactobacillus, diverse flora | As a side dish; start small |
| Miso | Aspergillus, Lactobacillus | Miso soup; don't boil (kills bacteria) |
| Kombucha | Bacteria and yeasts | 4-8 oz daily; watch sugar content |
| Traditional buttermilk | Lactobacillus | 1 glass with or after meals |
Choosing Probiotic Supplements
- Look for specific strains (e.g., Lactobacillus rhamnosus GG, not just "Lactobacillus")
- Check CFU count (colony forming units) - usually 1-10 billion
- Ensure viability at time of use (check storage requirements)
- Match strain to condition when possible
🍯 Kitchen Remedies
Apple Cider Vinegar
Claimed uses: Acid reflux, digestion aid, blood sugar control
Evidence: Limited scientific evidence; may help blood sugar modestly. Claims for reflux are contradictory.
If using: 1-2 tablespoons diluted in water before meals. Never undiluted (damages teeth and esophagus).
Caution: Can worsen reflux in some people; may interact with diuretics and insulin.
Honey
Uses: Sore throat, wound healing, potential antibacterial properties
Evidence: Manuka honey has antibacterial properties; may help with H. pylori (limited evidence)
How to use: 1-2 teaspoons as needed; can add to teas
Caution: High in sugar; not for diabetics in large amounts. Never give to infants under 1 year (botulism risk).
Bananas
Uses: Diarrhea (BRAT diet), heartburn (alkaline), prebiotic fiber
Evidence: Traditional use; ripe bananas are easy to digest; green bananas have prebiotic resistant starch
How to use: 1-2 bananas daily; ripe for diarrhea, slightly green for prebiotic benefit
Rice Water
Uses: Diarrhea, stomach upset
Evidence: Traditional remedy; may help reduce stool output in diarrhea
How to use: Cook rice in extra water, strain, and drink the water when cooled
🧘 Mind-Body Approaches
Gut-Directed Hypnotherapy
Evidence: Strong evidence for IBS; 70-80% response rate in studies
How it works: Uses hypnotic suggestions to normalize gut function and reduce pain sensitivity
Access: Find certified practitioners; some apps available (e.g., Nerva)

Evidence: Good evidence for IBS symptom improvement
Beneficial poses:

Especially helpful for: Stress-related digestive issues, IBS, functional dyspepsia
Meditation and Mindfulness
Evidence: Reduces stress hormones that affect gut; may improve IBS symptoms
