The grain-free dog food scare started with a real concern about heart disease, but the early research did not prove that all grain-free foods were dangerous. Some researchers had financial ties to competing pet-food companies. Several named brands later introduced foods with grains, and Mars eventually bought Acana and Orijen. I think the business interests behind this story deserve a closer look. My suspicion that the scare could have helped set up a buyout remains a theory.
