Ev koppling hjärtsjukdom och spannmålsfritt? FDA undersöker.

Här är en ganska intressant text som en "Professor of Clinical Nutrition" på UC Davis School of Veterinary Medicine skrivit ihop om just detta.

Taurine is not required to be present in dog foods. Taurine is an amino acid that is not nutritionally essential for dogs; however, there are dietary factors (such as protein source, fiber type and concentration, and cooking or processing methods) and individual dog characteristics (such as breed and calorie needs) that impact how efficiently taurine may be made and used by the body. The sulfur amino acid content and bioavailability in food is important though. The problem with dietary deficiency-related cardiac disease is multifactorial and is not just seen in goldens.

1- in many grain free diets, legumes are used to provide the carb (starch) but also protein and fiber – you cannot tell which ingredients are providing various proportions of nutrients from an ingredient list

2- legume protein is low in sulfur amino acids (methionine and cystine- the precursors for taurine synthesis)

3- some fiber types/concentrations increase fecal taurine content and promotes bacterial degradation of taurine (dogs and cats must use taurine to conjugate bile acids) so taurine recycling is not as efficient and more is lost

4- dogs need an adequate supply of precursors and to be able to make taurine fast enough to replace obligatory as well as excessive losses. When Newfoundlands and beagles were compared (during the Investigation into the lamb and rice issue with DCM in the 90s), it was found that Newfoundlands made taurine more slowly, so there are differences among breeds and probably individuals

5- dogs with lower than predicted calorie needs (“easy keepers”) also might not eat enough food and therefore enough protein to supply adequate precursors

6- some grain free diets (and other types of diets), are not high in protein (and therefore sulfur amino acids) since they use more expensive exotic or uncommon sources.

Any of these or a combination may impact taurine status in the dog.
Så i princip så innehåller en del foder för mycket baljväxter som både hämmar skapandet av taurin och som gör att taurinet spenderas snabbare än hunden kan skapa mer. :down:
