What is the Processing Score?

Our Processing Score measures how much a food has been transformed from its natural state. The scale runs from 1.0 (single ingredient) to 32+ (ultra-processed)with higher scores indicating more processing.

Unlike other systems that rely on categories, we calculate exact scores based on:

  • Ingredient count: More ingredients = higher processing
  • Processing indicators: Artificial additives, preservatives, HFCS
  • Manufacturing complexity: Modified starches, hydrogenated oils
  • Chemical additives: Colors, flavors, emulsifiers

Score Distribution

Level 1 (≤2.5)15.7% of products
Level 2 (≤5.0)27.9% of products
Level 3 (≤8.0)25.4% of products
Level 4 (>8.0)30.9% of products

How Processing Scores Are Calculated

Base Score Formula

Base Score = log₂(ingredient_count) + 1

This gives us: 1 ingredient = 1.0, 2-3 ingredients = 1.5-2.5, 5+ ingredients = 3.5+

Processing Penalties

High Fructose Corn Syrup+1.5
Artificial Ingredients+2.0
Hydrogenated Oils+1.5
Preservatives (BHA, BHT)+1.5
Other Preservatives+0.6
Modified Starches+0.8

Example Calculation

Processed Snack Cake:
Base (15 ingredients): 4.9
+ High Fructose Corn Syrup: +1.5
+ Artificial Flavors: +2.0
+ Preservatives: +0.6
Final Score: 9.0

Processing Levels Explained

Level 1: Minimally Processed (≤2.5)

15.7% of products

Single ingredients or minimally processed foods with 2-3 simple ingredients. No artificial additives or complex processing.

Level 2: Processed (≤5.0)

27.9% of products

Foods with simple processing like canning, freezing, or basic preparation. May contain salt, sugar, or natural preservatives.

Level 3: Highly Processed (≤8.0)

25.4% of products

Products with multiple processing steps and some artificial ingredients. May contain preservatives, stabilizers, or flavor enhancers.

Level 4: Ultra-Processed (>8.0)

30.9% of products

Industrial formulations with multiple artificial additives, preservatives, and ingredients not found in home kitchens. High levels of processing.

Processing Scores by Food Category

Average processing scores vary significantly by food category, revealing patterns in industrial food production:

CategoryProductsAvg Processing ScoreAvg Nutrition ScoreProcessing Level

Snacks & Candy534,4928.784.84Ultra-Processed
Bakery136,97311.904.55Ultra-Processed

Key insights: Bakery products have the highest average processing scores (11.90), while canned/jarred foods are surprisingly well-processed (4.07). Snacks & candy represent the largest ultra-processed category with over 534,000 products.

Tips for Finding Lower Processing Scores

🛒 Shopping Strategies

  • Shop the perimeter: Fresh produce, dairy, and meat typically have lower scores
  • Read ingredient lists: Shorter lists usually mean lower processing
  • Avoid HFCS: High fructose corn syrup adds significant processing penalty
  • Look for single ingredients: Items like nuts, oils, grains score 1.0-2.0

⚠️ Red Flags to Avoid

  • ×Artificial colors/flavors: Major processing score penalties
  • ×BHA, BHT preservatives: Industrial antioxidants with +1.5 penalty
  • ×Hydrogenated oils: Trans fats and high processing scores
  • ×Long ingredient lists: 15+ ingredients usually mean ultra-processing
