Hook
**90 % of serotonin is produced in the gut—feed your microbes, and you feed your mind.**
TL;DR
- Target **30 plant foods/week** for maximum diversity
- Daily stack: **prebiotic fibre + fermented food** = more butyrate
- Stress, sleep and exercise shape the microbiome as much as diet
What is the gut microbiome?
Trillions of bacteria, fungi and viruses living in the colon; they digest fibre, make vitamins K/B and modulate immunity and mood via the gut‑brain axis.
Prebiotic power foods
| Food (per serve) | Prebiotic fibre (g) | Extra perks |
|------------------|---------------------|-------------|
| Chicory root (10 g) | 6.6 | Coffee substitute |
| Green banana flour (20 g) | 8 | Resistant starch |
| Oats (40 g) | 3 | β‑glucans lower LDL |
| Cooked then cooled lentils (½ cup) | 4 | Plant protein |
Probiotic all‑stars
- **Kefir** – 12 – 40 billion CFU/serving (L. kefiri)
- **Kimchi** – lactobacilli ferment cabbage + chilli; source of vitamin K2
- **Miso** – Bacillus subtilis natto strain produces nattokinase
Postbiotics & SCFAs
Short‑chain fatty acids (butyrate, propionate) fuel colon cells, tighten gut barrier and reduce inflammation. Goal: ≥ 15 g fermentable fibre/day.
Lifestyle levers
- **Sleep**: < 6 h cuts Akkermansia 40 %
- **Exercise**: 150 min/week ↑ butyrate producers
- **Stress**: 10‑min meditation ↓ cortisol, restores microbial balance
1‑day gut‑loving menu (~40 g fibre)
• **Breakfast**: Overnight oats with kiwi & chia
• **Lunch**: Lentil‑quinoa bowl, rocket, tahini‑miso dressing
• **Snack**: Kefir smoothie + frozen berries
• **Dinner**: Grilled trout, cooled sweet‑potato salad with kimchi
Pro tips
- Rotate fermented foods—different strains each week.
- Add cooled starch (rice, potatoes) for resistant starch type 3.
- Polyphenols (cocoa, berries) act as ‘bacterial fertiliser’.
Myth vs fact
| Myth | Fact |
|------|------|
| “Take one probiotic pill—problem solved.” | Strains are niche; diet diversity still key.
| “All fermented foods are probiotic.” | Must contain live cultures (pasteurised sauerkraut ≠ probiotic).
| “Fibre causes bloating, so avoid it.” | Gradual increase + water prevents discomfort.
Take‑home message
Feed microbes with diverse fibres, add live ferments, sleep well and move—your gut ecosystem will repay you with better digestion, immunity and mood.
