Ultra-Processed Foods: Understanding New Research and a New database: GroceryDB and TrueFood

by Charles Platkin, PhD, JD, MPH

Have you ever found yourself squinting at a food label, trying to decipher a list of ingredients that reads more like a chemistry experiment than a recipe? You’re not alone. The modern supermarket has become a labyrinth of ultra-processed foods (UPFs), products that have transformed from simple ingredients into complex formulations through industrial processing. While these items offer undeniable convenience and extended shelf life, they’ve also sparked growing concern in the scientific community and among health professionals.

Recent studies paint a startling picture: UPFs now constitute between 57% and 73% of the average diet in developed nations, with the United States leading this trend. These aren’t just frozen dinners or obvious junk foods – UPFs have infiltrated nearly every aisle of the grocery store, from breakfast cereals to bread, from snack bars to yogurt. But what exactly makes a food “ultra-processed,” and how can consumers navigate this increasingly complex landscape? Here is a list from Dr. Marion Nestle, Foodpolitics.com (she compiled from a few sources), about various issues and concerns regarding UPFs:

The Challenge of Processing Classification

The journey of food from farm to table isn’t always straightforward. Processing exists on a spectrum, ranging from minimal interventions like washing and packaging fresh produce to complex industrial processes involving multiple chemical modifications. Traditional food processing methods – fermenting cabbage into sauerkraut, milling wheat into flour, or pasteurizing milk – have been used for centuries and often enhance food’s nutritional value or safety. However, modern ultra-processing goes far beyond these traditional methods.

Ultra-processed foods typically contain ingredients that you’d never find in a home kitchen: modified starches, hydrogenated oils, protein isolates, artificial sweeteners, emulsifiers, and synthetic vitamins. These industrial formulations often combine five or more ingredients, many of which serve purely technological functions – enhancing texture, extending shelf life, or intensifying flavors. The result? Products that are highly palatable, convenient, and profitable, but potentially problematic from a health perspective.

The Birth of GroceryDB

Enter GroceryDB, a groundbreaking initiative that emerged from an unprecedented collaboration with Northeastern University, Harvard Medical School, University of Copenhagen, and other leading research institutions. This comprehensive database, encompassing over 50,000 food items from major U.S. retailers, represents the first systematic attempt to quantify food processing at scale.

See: https://pubmed.ncbi.nlm.nih.gov/39806219/ and https://pmc.ncbi.nlm.nih.gov/articles/PMC11177926/

What sets GroceryDB apart is its sophisticated approach to analyzing food products. Rather than relying on simple categorization, the system employs advanced machine learning algorithms to examine multiple dimensions of each product:

  • Ingredient complexity and interactions
  • Presence and quantity of industrial additives
  • Nutritional composition and density
  • Processing methods and techniques
  • Presence of artificial preservatives and enhancers
  • Chemical modifications to the original ingredients
  • Added sugars and their forms
  • Industrial protein sources and modifications
  • Synthetic micronutrients and fortification

The FPro Score: A Smart Metric

At the heart of GroceryDB lies the Food Processing Score (FPro), a sophisticated metric that evaluates processing levels on a continuous scale from 0 to 1. This scoring system represents a significant advancement over previous binary or categorical classifications. Here’s how the scale breaks down:

0.0-0.2: Minimally processed foods

  • Fresh fruits and vegetables
  • Raw nuts and seeds
  • Single-ingredient items without additives

0.2-0.4: Basic processed ingredients

  • Pasteurized milk
  • Traditional flour
  • Simple canned vegetables
  • Basic fermented foods

0.4-0.7: Moderately processed foods

  • Traditional breads
  • Basic pasta products
  • Simple preserved foods
  • Minimally sweetened dairy products

0.7-1.0: Ultra-processed foods

  • Most packaged snacks
  • Carbonated beverages
  • Many breakfast cereals
  • Processed meats
  • Ready-to-eat meals
  • Industrial baked goods

The FPro score’s sophistication lies in its ability to consider multiple factors simultaneously. It draws on established frameworks like NOVA while incorporating new insights from nutrition science and food technology. The algorithm examines not just the number of ingredients, but their interactions, processing methods, and potential health implications.

The Economic Dimension

One of GroceryDB’s most striking findings, published in a 2024 Nature Food study, reveals a troubling economic pattern: for every 10% increase in processing level, there’s typically an 8.7% decrease in price per calorie. This creates a perfect storm of accessibility and health impact. Ultra-processed foods aren’t just convenient – they’re often the most affordable option for calorie-dense nutrition.

This price-processing relationship has profound implications for public health and social equity. Lower-income communities often face a double burden: limited access to fresh foods and economic pressure to choose more heavily processed options. The data from GroceryDB helps quantify this relationship, providing valuable insights for policymakers and public health officials working to address nutrition security.
