Methods
Every claim has a paper trail.
Marketing pressure and factual accuracy pull in opposite directions. This is the process we use to make sure accuracy wins by default rather than by argument.
Evidence levels
Four levels, labelled honestly.
Not all support is equal, and collapsing the difference is how brands mislead people without technically lying.
- Industry background
- Published research about the crop category in general. Supports context — not a statement about LUYA.
- Internal testing
- LUYA's own measurements. Real, but not independent; always reported with hardware and recipe versions.
- Independent verification
- Testing or measurement by an outside party. Reported with who did it and under what scope.
- Peer-reviewed
- Published and reviewed research. Linked to the original source, never paraphrased into a stronger claim.
The record
What we track for every factual statement.
Each claim used on the site carries a record: what exactly is being stated, which domain it belongs to, its evidence level, its source, the scope it applies to, the scope it explicitly does not apply to, its review status, and its expiry date.
- Scope is mandatory
- Crop, hardware version, environment and region — a result outside its scope is not a claim, it is an extrapolation.
- Non-applicability is published too
- What a result cannot be used to conclude sits next to the result itself.
- Claims expire
- A dated claim goes back for review rather than quietly ageing on a page.
- Unapproved means unpublished
- Draft or restricted claims do not appear on product or marketing pages. There is no 'temporarily' about it.
Language rules
Words we do not use.
Precision in wording is part of the method, not a legal afterthought.
- No absolutes
- 'Guaranteed', 'zero risk', 'always', 'eliminates' — a growing system cannot honestly promise any of them.
- No borrowed authority
- No institution name or logo without a signed agreement and their approval.
- No implied medical benefit
- Nutrients are described as nutrients, not as treatments.
- No fear framing
- We describe what fresh food offers, not what the reader's current diet is doing to them.
