FODMAP/SIBO Rating

Avoid

Serving Size Consideration: One standard serving of kimchi

Safe Serving Size: Small amount for testing tolerance

Active Compounds: Fructans, GOS (Galacto-oligosaccharides), and Mannitol from cabbage and garlic

Fermentation Level:
High

Digestive Impact

Why it's problematic: High in fermentable carbohydrates from cabbage, garlic, and other ingredients

Specific symptoms: Bloating, gas, abdominal pain, and possible digestive discomfort

Typical reaction time frame: Symptoms typically appear within 30 minutes to 4 hours after consumption

Individual variation: Tolerance varies significantly; some may handle small amounts while others react strongly

Safe Alternatives

Substitution ratio: 1:1 replacement for similar fermented vegetables

Processing Effects

Fermentation can slightly reduce FODMAP content but not enough to make it low FODMAP

Cooking does not significantly affect FODMAP content

Stacking Considerations

Avoid combining with:

  • cabbage
  • garlic
  • onion
  • leeks

Safe complementary foods: Can be eaten in small amounts with rice, proteins, and low FODMAP vegetables

Reintroduction Guidelines
  1. Start with 1 teaspoon (5g) of kimchi
  2. Wait 24-48 hours to assess tolerance
  3. If no symptoms, increase to 2 teaspoons
  4. Gradually increase to desired portion size if tolerated

Signs of success: No digestive symptoms within 48 hours of consumption
