General Mills Inc. has settled four proposed class actions alleging the company use of the term “100% Natural” on its Nature Valley products was deceptive and misleading because they contain genetically modified organisms and other synthetic ingredients.

The agreement prevents Minneapolis-based General Mills from claiming that its Nature Valley granola bars, crispy squares, and trail mix bars are “100% Natural” if those products contain corn syrup, soy lecithin, glycerin, maltodextrin, or several other artificially produced ingredients. Those products must also not contain more than a trace of any ingredients derived from bioengineered crops or plant material.
