Hi Howard,
Food ratings on this site are based solely on label information. There is an inherent flaw in rating foods this way and this is addressed in various articles on the site. I agree that at this time, there is very real and very concerning information regarding diets of certain types. Until more is known, I’d agree with your veterinarian that it is best to avoid feeding suspect diets/ingredients and instead feed diets with well tested and understood ingredients.
Because diabetes in dogs is not diet related, except perhaps in relation to fat contributing to pancreatitis, and cancer has not been linked to any particular diet type it is immaterial that more dogs have been diagnosed with those conditions than diet related DCM.
Currently a lot is unknown and it may be years before diet related DCM is understood. In some ways the current DCM situation parallels the vaping situation. With vaping there is a correlation to presence of Vit E acetate in the vaping product, in diet related DCM there is a correlation to certain ingredients and grain free diets. In both situations other factors may also be in play and the definitive cause isn’t yet known.
As of Jan 21, 2020, according to the CDC, 60 deaths have occurred. Total number of death from DCM is unknown as mandatory reporting isn’t in place but certainly exceeds 60.
Some people may say only 60 people have died, vaping has been popular for decades and there is no reason not to vape. Others will find the risk of death from a product without any benefit unacceptable. The diets associated with DCM have no clear benefit and appear to carry a risk of death. Stores are taking the initiative to ban products. Veterinarians , to use your word “outlawed” grain free.
People will still vape and people still feed grain free because they evaluate risks differently.
I stick with companies that have demonstrated a vested interest in the nutritional health of all dogs through their continued feeding and monitoring of dogs in their diet research centers and contributions to nutritional research . Consulting with a veterinary nutritionist for a diet formulation or passing a feeding trial is not enough in my opinion.
