Why Does This Score Ultra-Processed?
In our analysis, Comfort Steak Portabella scores Ultra-Processed. That classification is shaped by ingredients commonly associated with ultra-processed foods:
- Modified Starches (Modified Cornstarch): Chemical modification is a hallmark of UPF.
- Stabilizers & Gums (Carrageenan, Pectin, Xanthan Gum): Industrial stabilizers common in UPF.
Within Frozen Dinners, this product is more processed than about 37% of the 5,358 products we've analyzed.
Processing classification reflects ingredient and additive analysis, not a judgment of any product's safety, quality, or healthfulness.
