Sugar, Processing, and the Sugar Penalty Rule

WISEcode's classification engine applies a sugar penalty to any product that derives more than 20 percent of its calories from added sugar. This article explains why the rule exists and how it interacts with the rest of the methodology.

The rule

If a product gets more than 20 percent of its total calories from added sugar, the classification engine applies an automatic metabolic penalty. This penalty applies regardless of how the rest of the ingredient list scores on the processing scale.

Why a separate penalty

The processing scale captures how an ingredient is made. It does not, on its own, capture metabolic load. Added sugar contributes a metabolic effect that is meaningful even when the rest of a product's ingredients are minimally processed. The sugar penalty is how the classification recognizes that effect.

How the threshold is calculated

The denominator is total calories per serving. The numerator is calories from added sugars, as declared on the Nutrition Facts Panel. If that ratio exceeds 20 percent, the penalty applies.

Implications for reformulation

For products that are otherwise close to Non-UPF Verified™ status, reducing added sugar below the 20 percent threshold can be one of the highest-impact changes in a reformulation roadmap. See the Reformulation Roadmap article for related strategies, including the "Sugar Trap" pattern.
