Safe Serving Size: Small portion as condiment

Active Compounds: Fermentable oligosaccharides from cabbage, naturally occurring probiotics

Fermentation Level:
High

Digestive Impact

Why it's problematic: Can be problematic in larger portions due to fermentable components

Specific symptoms: Bloating, gas, and digestive discomfort may occur with excessive intake

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

Individual variation: Tolerance varies significantly between individuals, particularly based on gut microbiome composition

Safe Alternatives

Substitution ratio: 1:1 replacement for fresh vegetables

Processing Effects

Fermentation reduces some FODMAPs but creates other fermentable compounds

Smaller portions are better tolerated

Rinsing can help reduce fermentable compounds

Stacking Considerations

Avoid combining with:

  • kimchi
  • kombucha
  • cabbage
  • brussels sprouts

Safe complementary foods: Pair with low FODMAP proteins and grains like rice, chicken, or fish

Reintroduction Guidelines
