How to Get Started

STEP 1

THE NUMBERS (3 minutes)

In your body right now:
- Human cells: ~30 trillion
- Bacteria cells: ~38 trillion
- You're 56% bacteria by cell count!
Most bacteria live in:
- Gut (large intestine)
- Skin
- Mouth
- Nose
Weigh about 2-6 pounds total

STEP 2

WHAT THEY DO (4 minutes)

Beneficial bacteria help:
- Digest food (especially fiber)
- Produce vitamins (K, B12)
- Train immune system
- Protect against harmful bacteria
- Regulate mood (gut-brain connection)
- Maintain skin barrier
Without them:
- Can't digest many foods
- Weaker immune system
- More prone to infections
- Digestive problems
They're not invaders - they're partners!

STEP 3

THE MICROBIOME (3 minutes)

Your unique bacterial community
Like a fingerprint - everyone's is different
Established early in life:
- Birth (vaginal delivery vs C-section)
- Breastfeeding
- Environment
- Diet
Changes throughout life:
- Antibiotics can disrupt
- Diet affects composition
- Stress impacts balance
- Travel introduces new bacteria

STEP 4

KEEPING THEM HEALTHY (2 minutes)

Feed your microbiome:
- Fiber (prebiotics)
- Fermented foods (probiotics)
- Diverse diet
Avoid damage:
- Unnecessary antibiotics
- Overly sterile environment
- Processed foods
Healthy gut bacteria = healthier you!
