Fiber Density
What you actually feed when you feed yourself.
The raw material your gut microbiome needs to produce short-chain fatty acids — which regulate roughly half the human immune response.
What the research says
You feed two organisms every time you eat. One of them is you. The other is the colony of 10-100 trillion microorganisms in your large intestine.
The microbiome ferments the fiber you can't digest and produces short-chain fatty acids (butyrate, acetate, propionate) that regulate immune function, mood, glucose, cognition.
The Blue Zone populations — Sardinia, Ikaria, Okinawa, Nicoya, Loma Linda — eat beans every day. Not once a week. Every day.
Target: 30 different plants per week. The diversity matters more than the volume.
