GMO feeding studies: a look at how these should be designed and what flags readers should look for when reviewing these studies.
Studies that involve animals are especially complex, since you cannot “redo” a failed experiment as easily as you can with in vitro or in silico assays. Criticisms by reviewers and editors can seldom be addressed during the peer review process: if an editor or reviewer identifies a flaw in an animal feeding study, it often cannot be redone due to resource constraints.
Poorly designed GMO feeding studies abound, quite possibly due to these difficulties in performing any animal feeding study. Such studies are often used by people who claim GMO are dangerous.
