Consumer Reports tested a wide variety of processed foods with corn or soy ingredients on the label as a snapshot of the current US market. We only selected products with corn or soy on their ingredients list.
We purchased and tested products that were conventional, claimed to be “Natural”, “Organic”, or made some type of verified or unverified “Non‐GMO” claim. We tested at least two samples of each product, each sample from a different lot. All products were purchased between April and July of 2014. It is important to note that between testing and publishing, there were manufacturers who were obtaining or obtained Non‐GMO Project Verified certification. This demonstrates an actively changing market that seems to be responding to consumer demand.
