Hi Mike P –

You’re right – potato has a high glycemic index. However what you want to look at is glycemic load – glycemic load measures how the food will impact blood sugar based on the amount of the food eaten. Meaning, just because a food contains an ingredient that is high glycemic doesn’t necessarily mean the food as a whole is high glycemic. For example, Orijen contains white potato (a high glycemic ingredient) however, because they use such a small amount of white potato and such a large volume of meat, the food as a whole is low glycemic (certified low glycemic by the glycemic research institute). Looking at EVO’s protein content (without calling the company) I would assume the food is likely low glycemic. Also, not all of EVO’s formulas contain white potato – the weight management formula (which looks like a wonderful option for dogs with diabetes) is white potato free and has 52% protein and 15% fat, the fish formula is white potato free as well. Now on the flip side, you could use a binder with a lower glycemic index than white potato but if the food is a lot lower in protein/contains much less meat and higher in carbs/contains more binder – that food could actually have a greater impact on blood sugar then a food that contains a large volume of meat and a small amount of a high glycemic binder. White potato and tapioca are both high glycemic but if used in a high quality food with a large volume of meat and only minimum amounts of binders, they shouldn’t affect blood sugar significantly. That’s my understanding (James feel free to correct me if I’m wrong).
