Why Does This Score Ultra-Processed?
In our analysis, Mega Stuf O's Cereal scores Ultra-Processed. That classification is shaped by ingredients commonly associated with ultra-processed foods:
- Corn-Based Sweeteners (Corn Syrup, High Fructose Corn Syrup): HFCS is a hallmark of ultra-processed foods.
- Processed Fruit Products (Cocoa (Processed With Alkali), Unsweetened Chocolate): Concentrates and extracts indicate significant processing.
- Emulsifiers (Soy Lecithin): Industrial emulsifiers indicate UPF.
Within Breakfast Cereal, this product is more processed than about 77% of the 9,419 products we've analyzed.
Processing classification reflects ingredient and additive analysis, not a judgment of any product's safety, quality, or healthfulness.
