Maybe it's a good idea to look at the glycemic index of these ingredients. I know that sweet potatoes are better for diabetic people than white potatoes. the Glycemic index relates to how sugars are processed by our bodies. I know ferrets are not Humans, but both humans and ferrets can have blood sugar level issues. How it helps to look at this: for example: sweet potatoes will give a more steady release of sugars, whereas white potatoes will spike a persons glucose level, setting them up for a crash, much like drinking a soda Does anyone know how these things relate to ferrets, and if this could be a useful tool in choosing the best foods for our kids?
