NOVA Food Processing Levels

Use the NOVA 1–4 system to map foods by processing level and build menus around minimally processed anchors.

Front-of-Pack (FOP) Nutrition and Processing Indicators

Processing degree is a starting signal: NOVA 3 or 4 items can still play a role when they add safety or nourishment—balance them with whole-food staples rather than chasing perfection.

Group 1 — Unprocessed or Minimally Processed

Whole foods like fresh produce, grains, legumes, eggs, and plain yogurt. Processing here may include cleaning, freezing, or fermentation without additives.

Group 2 — Culinary Ingredients

Ingredients extracted from Group 1 foods—oils, butter, sugar, and salt—used to season and prepare meals. Valuable in small amounts to cook or preserve.

Group 3 — Processed Foods

Products combining Group 1 and Group 2, such as breads, canned vegetables, cheeses, or tinned fish. Typically feature two or three ingredients and retain a recognisable base food.

Group 4 — Ultra-Processed Foods

Industrial formulations with additives for flavor, color, or shelf life—think soft drinks, packaged snacks, instant noodles, and reconstituted meats. Treat as convenience items alongside fresh staples.

Curator's Notes

We translate NOVA research into grocery reality, highlighting pantry examples, ingredient cues, and ways to combine convenience with fresh prep. Tools include printable checklists and classroom-ready explanations.
