The evidence, told like a story.
Plant-based nutrition is full of fascinating research — and a lot of overstatement. These interactive stories walk through what real studies found, what they suggest, and, just as importantly, what they don't prove.
Same Genes, Different Dinner Table
When people of Japanese ancestry moved from Japan to Hawaii to California, their genes traveled — but their environment changed. So did their disease patterns.
What 65 Counties Can — and Can't — Tell Us
One of the largest snapshots of diet and disease ever taken. A brilliant curiosity engine, and a perfect lesson in what observational research can and cannot say.
A Wartime Natural Experiment
During the WWII occupation of Norway, the national diet changed and so did deaths from circulatory disease. A fascinating natural experiment — and a heavily confounded one.
Protein & Dairy Myths
Flip-card myth-busting: where protein really comes from, why cows are built on plants, and what lactose tolerance says about us.
Bust some myths →Evidence badges
Every story is tagged with the kind of evidence behind it. Stronger-sounding claims need stronger study designs — the badges keep that visible.
- Migration Study
- Compares the same ancestral group living in different places to see how environment tracks with health.
- Observational
- Watches what happens in real populations. Can show associations, not cause and effect.
- Ecological
- Compares whole groups or regions rather than individuals. Useful for hypotheses, prone to confounding.
- Historical Natural Experiment
- A real-world event changed conditions for a population. Informative, but never tightly controlled.
- Clinical
- Studies in patients or trial participants, often with measured interventions.
- Mechanism
- Explains how something works biologically. Explains 'how', not 'how much it matters'.
- Practical Takeaway
- An everyday, do-this-today summary grounded in the evidence above.
