A review of researchers’ industry relationships is receiving renewed attention this week. Its original institutional explanation was published on 24 September, before the latest coverage.

The sample behind the number
The review examined 69 papers published between 2009 and 2025 that criticised the NOVA classification or discussed potential benefits of ultra-processed foods. It identified at least one industry-affiliated author in 91.3% of those papers.
That denominator matters. This was a selected body of work, not every paper about food, every NOVA critique or a random sample of nutrition scientists.

A relationship is a disclosure question, not a verdict
The investigators looked at disclosed relationships and publicly identifiable links. Oregon Research Institute’s explanation also recognises that criticism can identify real ways to improve a classification system.
An industry connection does not, by itself, show that a finding is false. It does give readers a reason to inspect funding, methods and the distance between results and promotional claims.
