Regarding low glycemic claims, AAFCO recently ruled that there is no standard for what constitutes “low glycemic” ingredients or products for pet food. Such claims could also be false and misleading because the claims imply an effect on the structure/ function of the body that has not been substantiated in dogs and cats, and they are implied drug claims (treat or prevent diabetes). AAFCO has now ruled that any claims of low glycemic foods should not be made any longer. 
 
Regarding carbohydrates, The 2017 AAFCO Official Publication for pet food states that nitrogen-free extract and carbohydrate guarantees are not necessary and meaningful to consumers because they are misleading, and discourages these guarantees. 
 
In addition, there is currently no standard for what constitutes “low carbohydrate” ingredients or products for pet food or “reduced carbohydrate” products; these statements can be considered false or misleading. AAFCO has now ruled that any claims of low glycemic foods should not be made any longer.Â
