Where corn sits in the Sniff System
The methodology treats corn as neither positive nor negative on its own. Whether it lifts or hurts a product's score depends on context: position in the ingredient list, ratio to higher-quality ingredients, and the rest of the formulation.
Every methodology choice is published, citeable, and subject to revision when new evidence arrives. Read the full Sniff methodology for the formulas behind every score component, or file a correction if you think this position is wrong.
