Autophagy — cellular self-cleaning — is activated by fasting and is linked to longevity and cancer prevention.

🔬 Science Fact #7257

The gut contains over 100 million neurons — it's often called the 'second brain' due to its independent nervous system.

🫀 Human Body Fact #7256

The appendix functions as a reserve for gut bacteria — helping replenish the microbiome after illness.
