Recently, the USDA removed the ORAC database from its website and replaced it with a statement about ORAC (original here Open in a new window). There are specific comments in this statement that we believe are misleading or incorrect and require a forceful response.
First, we would like to establish some important foundational facts:
1. No in vitro assay that quantifies a characteristic of a nutritional product describes in vivo outcomes and should not be used to suggest such a connection.
2. Vital information about metabolism, bioavailability, mechanisms of action, and efficacy is not measured by any such in vitro assay.
3. There is evidence that polyphenols are connected to beneficial human health outcomes
4. There is evidence that these beneficial outcomes have antioxidant as well as diverse other mechanisms of action.
5. ORAC has been and remains a valuable analytical tool in connection with other investigative methods.
Ronald L. Prior, PhD, has written an authoritative and compelling response to the USDA statement. Dr. Prior is well qualified for the task. He was senior researcher at the Agricultural Research Service of the USDA for more than 30 years where he led research related to phytochemicals and health.
Brunswick Labs, which has been a leader in antioxidant analysis for over a decade, will continue to develop innovative methods that add value to companies in the food and nutrition industries.
