Polydextrose in Pet Food

Grade B-1 ptsFiber & Superfoods

What It Is

"A synthetic soluble fiber and bulking agent made from dextrose."

Health Impact

Despite being built from sugar, the manufacturing process links it into a form that isn't digested as sugar — it functions as a low-calorie soluble fiber instead, mainly used to add bulk and texture in reduced-calorie formulas without the blood sugar impact of an actual sugar. Generally well tolerated, though a synthetic fiber source rather than a whole-food one. Score: 6/10.

Why This Grade

A minor caveat applies — usually a processing step (e.g. rendering into a meal), a moderate allergen history, or a named-but-fattier source — but nothing on our risk watchlist. -1 pt deducted.
