Guidelines & consensus
Major professional and public-health bodies when guidance is relevant to the question.
THE EVIDENCE DESK
Evidence before theatre.
A practical evidence layer for longevity buyers: established guidance first, emerging signals clearly labelled, provider claims kept in their proper place.
READ THE CLAIM, THEN THE SOURCE
The more expensive the promise, the more carefully we look at what supports it.
OUR EVIDENCE HIERARCHY
Randomised evidence
Trials and systematic reviews, interpreted for the actual population studied.
Observational evidence
Useful for associations and hypothesis generation, not proof of causality.
Provider / proprietary
Important for describing what is sold; not sufficient on its own to establish clinical benefit.
CORE REFERENCES
Sources we can
stand behind.
This is not a comprehensive medical bibliography. It is the core reference layer used for our current editorial explainers.
WHO — Healthy diet
Core healthy-diet principles; emphasis on whole grains, vegetables, fruit, legumes, nuts and limiting excess sugar, sodium and unhealthy fats.
Open source ↗WHO — Physical activity
Adult guidance of 150–300 min moderate aerobic activity or 75–150 min vigorous activity weekly, plus muscle strengthening on 2+ days.
Open source ↗AASM / Sleep Research Society
Consensus recommendation that healthy adults obtain seven or more hours of sleep per night on a regular basis.
Open source ↗New England Journal of Medicine — PREDIMED republication
Randomised prevention trial in 7,447 high-risk adults aged 55–80; revised analysis of Mediterranean-diet interventions and cardiovascular events.
Open source ↗What we deliberately do not do.
We do not translate a biomarker score into a diagnosis. We do not recommend screening purely because a technology exists. We do not turn an association into a causal promise. We do not infer that a resort programme extends lifespan.
On provider profiles, official programme descriptions are factual only as descriptions of what the provider currently publishes. Their outcome claims remain provider claims unless independently supported.
