🟡 Phosphoric Acid in Pet Food

Grade C-2.5 ptsPreservatives

What It Is

"A synthetic acid used to adjust pH and provide a tart flavor."

Health Impact

Used as an acidifier and mild preservative. In human nutrition research, high phosphoric acid intake (notably from cola) has been studied for a possible association with reduced bone density; the amounts used in pet treats are far smaller and not established as a comparable risk, but it's a synthetic acid added for function, not nutrition. Score: 4/10.

Why This Grade

A real but unresolved concern: often an ongoing FDA/AAFCO research question (like the grain-free/DCM investigation), a common allergen, or a vague-but-not-alarming label claim. -2.5 pts deducted.
