In July 2018, the FDA announced it was investigating whether or not there is a link between grain free diets, low taurine, and the suspected increased occurrence of Dilated Cardiomyopathy (DCM). The FDA provided an update in June 2019, which contained its research to-date, and communicated that it is continuing the investigation.
The research presented does not show a definitive dietary link between grain free diets, or any specific ingredient, and the occurrence of DCM. While grain free, high legume diets are more represented than whole grain recipes in the data, an apparent correlation does not automatically imply cause. Much more still needs to be learned about this very complex issue before anyone can definitively draw conclusions about what role, if any, is played by diet, in the apparent increase in diagnoses of DCM.
