New study on the link between heart disease and grain-free diets.
From a client who recently participated in a dog forum:
“Today I was on a couple dog forums, and people were writing about the link between grain-free dog diets and heart damage. Apparently, lentils, legumes, peas, beans, and potato may cause dilated cardio-myopathy in some dogs. No one is sure of the reason, but it could have to do with these vegetables blocking taurine in dogs.”
“Here is a research paper:

“I don’t know if taurine supplements can solve the problem, and obviously, not all dogs get this, but it seemed important since dilated cardio myopathy can go for a long time before symptoms start.
Anyway, I thought you might be interested. Labs are not necessarily prone to DCM, but it is occurring in some labradors that have grain-free diets. It seems like it may still be early days for these studies, but there are plenty of anecdotal stories online in forums, so I thought I’d pass that along in case it is of interest.”
In recent years, an increasing number of dogs have developed dilated cardiomyopathy while eating certain grain-free diets rich in legumes like peas and lentils. The aim of this article is to review and discuss recent scientific research to ...
