"This latest review by researchers long associated with the organic
industry flies in the face of existing research that has not found any
significant nutritional difference between organic and conventionally
raised foods."

The article cited above does not include any actual references to support their view that "existing research has not found". Here are two that have found differences:

H.Kuska comment: The first link is of particular timely interest due to its finding of glyphosate residues.

The following link is to an announcement this morning that the EPA will now test food for glyphosate:

"In other words, the differences found can be entirely due to the
difference between grass feeding and grain feeding – that’s it. That is
the real variable here, not organic vs conventional."

The actual statements in the abstracts of the original scientific research papers are:

For the Meat paper:

"Evidence from controlled experimental studies indicates that the high grazing/forage-based diets prescribed under organic farming standards may be the main reason for differences in FA profiles. Further studies are required to enable meta-analyses for a wider range of parameters (e.g. antioxidant, vitamin and mineral concentrations) and to improve both precision and consistency of results for FA profiles for all species. Potential impacts of composition differences on human health are discussed."

And for the Milk paper:

" It is concluded that organic bovine milk has a more desirable fatty acid composition than conventional milk. Meta-analyses also showed that organic milk has significantly higher α-tocopherol and Fe, but lower I and Se concentrations. Redundancy analysis of data from a large cross-European milk quality survey indicates that the higher grazing/conserved forage intakes in organic systems were the main reason for milk composition differences."

H.Kuska comment:

The author in the last link presented by Sclerid states: " It is therefore deceptive, in my opinion, to frame this difference as organic vs conventional when it is clearly grass-fed vs grain-fed."

H.Kuska comment: deceptive? Both abstracts included the information as I presented it above. If the author had produced the papers, he (of course) could have stated the research in whatever alternate ways he desired - subject to approval by the reviewers and editor

However, he was not the author. The present authors with the approval of the reviewers and the editor presented the information as published.
