Overview
The WISEcode Standard is a precision tool designed to help consumers distinguish between processed foods that are safe and products engineered to be addictive or harmful. While roughly 80% of food sold in the U.S. is packaged, traditional classification systems like NOVA tend to label nearly all packaged goods as equally "Ultra-Processed" (UPF). The WISEcode Standard provides the nuance needed to identify healthy options inside the center aisles of the grocery store.
Rather than treating "processed" as a single bucket, the Standard analyzes more than 5,000 specific ingredients and ranks them by their actual impact on human health. The result is a numeric score (Wc-UPF) that distinguishes a packaged food made with safe, refined ingredients from one built around additives, sweeteners, and substances of concern.
Why a New Standard Was Needed
Today there is no single U.S. or globally accepted definition of Ultra-Processed Food. NOVA, the most prominent existing system, was developed for food cultures centered on fresh ingredients and treats almost any packaged item as ultra-processed. That blunt approach penalizes all processing equally and doesn't help American shoppers tell the difference between a frozen vegetable, a shelf-stable yogurt, and a brightly colored snack engineered for over-consumption.
The WISEcode Standard takes a high-resolution, ingredient-level approach. It evaluates each ingredient on its own merits, applies an added sugar penalty based on a product's overall sugar load, and flags ingredients with established safety concerns separately so they don't get lost in an aggregate score.
The Three Scoring Factors
A product's Wc-UPF score is calculated from three specific areas:
1. Ingredient Quality (Processing Levels 1–4)
Every ingredient on a product's label is assigned to one of four processing levels, and each level contributes a weight to the score:
- Level 1 — Fortificant, Unprocessed or Minimally Processed (weight 0): Whole or minimally processed ingredients made with traditional methods such as washing, freezing, pasteurization, milling, fermenting, or cooking, with no solvent extraction and no health concerns. Also includes fortificants like essential vitamins, minerals, proteins, probiotics, and FDA-recognized fibers.
- Level 2 — Isolated or Refined Ingredients (weight 1): Purified fractions of whole foods (e.g., starches, sugar, refined seed oils), bioidentical synthetic replicas of natural compounds (e.g., citric acid, vanillin), or ingredients produced by industrial-scale separation or refinement that are not associated with health concerns.
- Level 3 — Industrial / Controversial Ingredients (weight 2): Ingredients typically produced through industrial means, such as additives that affect color, flavor, or shelf life, and that are often associated with markers of toxicity or inflammation.
- Level 4 — Ultra-Processed Ingredients of Concern (weight 3, plus a +16 "Super-Ultra" flag): Ingredients associated with severe health risks and/or those banned, restricted, or heavily regulated in the U.S., U.K., E.U., Canada, Australia, or New Zealand. Level 4 ingredients contribute their standard processing weight and also activate a categorical penalty of +16, reflecting concern that goes beyond incremental processing.
2. The Sugar Trap (Added Sugar Penalty)
Beyond the ingredients themselves, the Standard looks at how much of a product's energy comes from added sugar. The penalty (Psugar) scales with the percentage of total calories derived from added sugars:
- Less than 20% of calories from added sugar: 0 penalty points
- 20–29%: 1 point
- 30–39%: 2 points
- 40–49%: 3 points
- 50–59%: 4 points
- 60–69%: 5 points
- 70–79%: 6 points
- 80% or more: 7 points
Products that get more than 20% of their calories from added sugar receive an automatic penalty that pushes their final processing score higher — the "sugar trap" that catches otherwise simple-looking foods.
3. Red Flag Ingredients (Unique Ingredients of Concern)
Certain ingredients with significant safety concerns — such as carcinogenicity, genotoxicity, or serious regulatory concern — are designated as Unique Ingredients of Concern (UIC). Examples include Titanium Dioxide, Yellow 5 (and other artificial colors), and Nitrates. If a product contains any UIC ingredient, an additional +16 is added to its Wc-UPF score, automatically pushing it into the Super-Ultra tier regardless of the rest of its formulation.
How the Score Is Calculated
The Wc-UPF score combines the three factors into a single number:
Wc-UPF score = Σ (Ni × (i − 1)) + Psugar + (16 if any Level 4 / UIC ingredient is present)
Where Ni is the count of unique ingredients at processing level i (from 2 to 4), and Psugar is the added sugar penalty.
Interpretation Thresholds
The final score maps to one of five tiers, giving consumers a clear signal about what they're picking up:
- Minimal (0–3): Mostly whole foods, simple culinary ingredients, and one or two slightly processed ingredients.
- Light (4–6): Typically 6–12 ingredients, no more than 2 additives, and limited added sugar.
- Moderate (7–10): Around 10 ingredients, 1–3 additives, and 0–60% of calories from added sugar; may include zero-calorie sweeteners, natural flavors, or emulsifiers.
- Ultra (11–15): A dozen or more ingredients, often including artificial colors, flavors, sweeteners, emulsifiers, and preservatives.
- Super-Ultra (>15): Similar to Ultra but with even more concerning ingredients, including any UIC.
What Qualifies for Non-UPF Verification
Products in the Minimal, Light, or Moderate tiers are eligible for WISEcode's Non-UPF Verification, provided they contain no ingredients on the Unique Ingredients of Concern list. Products that fall into the Ultra or Super-Ultra tiers do not qualify.
A Living Standard
The WISEcode Standard is maintained as a living document. A Scientific Advisory Board reviews new evidence and convenes annually so the methodology continues to reflect current nutritional science as the food supply and research evolve.
