What counts as fermented food?
Foods transformed by beneficial microbes—e.g., kombucha (yeast + bacteria), sauerkraut (lacto‑fermented cabbage) and kimchi (spiced vegetables).
Evidence‑based benefits
1. **Microbiome diversity** – Stanford 2021 trial: fermented diet ↑ 26 % microbial diversity vs fibre‑only group.
2. **Lower inflammation** – same study saw ↓ IL‑6 and TNF‑α markers.
3. **Digestive relief** – meta‑analysis shows 47 % improvement in IBS symptoms with fermented veg.
Potential risks
- High sodium in store‑bought sauerkraut.
- Histamine sensitivity in some individuals.
- Kombucha: limit to 250 ml/day (acid & caffeine).
How to add them
- **Breakfast:** yogurt bowl + 2 tbsp kimchi.
- **Lunch:** sourdough toast + sauerkraut.
- **Dinner:** 200 ml kombucha mocktail.
Aim for 10–15 g fibre/day from veg to feed the new bugs.
