This is ONE of the theories the FDA is investigating, but it has not been proven to date. The FDA believes the potential association between diet and DCM in dogs is "a complex scientific issue and may involve multiple factors" including genetics. We KNOW that dogs can make taurine on their own from methionine and cysteine (these are precursors of taurine synthesis). It is believed that methionine and cysteine are less available from peas and lentils than other ingredients such as poultry. In addition, there is a belief that there may be something wrong with the methionine and cysteine in legumes that's not allowing dogs to convert them to taurine. This can be attributed so several things including the usage of Glyphosate - herbicide, as well as harvesting methods used.
Do legumes block taurine absorption in dogs?
