Key findings
- 1Standard fish sticks use minced fish blocks reformed into shapes, not whole fish fillets
- 2Sodium tripolyphosphate helps the fish retain added water, which adds weight
- 3Premium fillet-based fish sticks with simple breading (fish, flour, breadcrumbs, oil) are noticeably less processed
- 4In our analysis, fish sticks average a Processing Score of 8.2, which is Level 4
Why is Fish Sticks ultra-processed on average?
Fish stick manufacturing begins with frozen fish blocks made from minced pollock or cod. These blocks are sawed into rectangular portions, which is why all fish sticks have that uniform shape despite being made from a naturally irregular animal. The fish is combined with sodium tripolyphosphate (a moisture-retention agent that also makes the fish feel firmer) and often textured soy protein as a filler. The breading system is typically three layers: a pre-dust of modified wheat starch, a batter containing methylcellulose and leavening, and an outer crumb coating with added coloring. One overlooked detail: sodium tripolyphosphate helps the fish hold added water, which adds weight. In our analysis, fish sticks average a Processing Score of 8.2, which is Level 4.

How to read a fish sticks label
- 1
Check whether the fish is "minced" or "fillet"; fillet-based fish sticks are significantly less processed
- 2
Sodium tripolyphosphate (STPP) indicates water has been added to increase product weight
- 3
Look for short ingredient lists; some premium brands use just fish, breadcrumbs, and oil
- 4
Yellow 5 or annatto in the breading is a cosmetic additive to simulate a golden-fried appearance

Frequently asked questions
Are fish sticks real fish?
Yes, they contain real fish (usually Alaskan pollock or cod), but it is minced and reformed from frozen blocks rather than cut from whole fillets. In standard brands, breading and additives make up a meaningful share of the weight.
Are fish sticks worse than chicken nuggets?
In our analysis, fish sticks average a Processing Score of 8.2, which is Level 4. Search chicken nuggets to see their own average. Fish sticks often have slightly simpler formulations because fish protein binds more easily than chicken, requiring fewer binding agents.
What fish sticks are least processed?
Look for brands listing "cod fillet" or "pollock fillet" as the first ingredient rather than "minced fish." Dr. Praeger and some Trader Joe's varieties use whole fillets with simpler breading systems.
