Most of the food available in supermarkets today is processed in some way. Processing can be as simple as washing, cutting, freezing, or packaging — or as complex as refining, extracting, recombining, and adding chemicals to create products that no longer resemble their original ingredients.
The degree of processing matters. Lightly processed foods can still be nutritious. Ultra‑processed foods, however, are associated with poorer health outcomes, reduced nutrient density, and increased risk of chronic disease.
What Is Processed Food?
Processed food is any food that has been changed from its natural state. This includes:
- washing
- cutting
- cooking
- freezing
- drying
- adding salt, sugar, or oils
- combining ingredients
- packaging
Processing itself is not the problem. The type and extent of processing determine whether a food remains nutritious or becomes harmful.
Ultra‑Processed Foods (UPFs)
Ultra‑processed foods are industrial formulations made mostly from:
- refined starches
- extracted oils
- added sugars
- protein isolates
- artificial flavours
- colours
- emulsifiers
- stabilisers
- preservatives
These products are engineered for taste, convenience, and long shelf life — not for nutrition.
Examples include:
- soft drinks
- packaged snacks
- breakfast cereals
- instant noodles
- processed meats
- confectionery
- ready‑to‑eat meals
UPFs typically contain very few whole ingredients and very little natural nutrition.
Why Ultra‑Processed Foods Matter
Ultra‑processed foods are linked to:
- higher calorie intake
- lower nutrient density
- increased hunger
- metabolic dysfunction
- obesity
- cardiovascular disease
- type 2 diabetes
- digestive issues
- inflammation
They are designed to be hyper‑palatable, making it easy to overeat while still failing to meet essential nutrient needs.
Nutrient Density vs. Energy Density
Whole foods provide:
- vitamins
- minerals
- amino acids
- essential fats
- fibre
- phytonutrients
Ultra‑processed foods provide:
- energy (calories)
- additives
- refined carbohydrates
- industrial fats
This creates a mismatch: high energy, low nutrition.
The body continues to signal hunger because essential nutrients are missing, even when calorie intake is high.
How Nx will help...
Nx provides a nutrient‑centred way to evaluate food quality.
Instead of focusing on calories, Nx measures:
- essential nutrient density
- completeness
- balance
- bioavailability
This allows consumers to compare foods based on what the body actually needs — not on marketing claims or packaging.
Nx will identify:
- which foods deliver essential nutrients
- which foods are nutritionally empty
- how processed foods compare to whole foods
- how to build meals that meet human nutrient requirements
The Goal
The aim is not to eliminate all processed foods. The goal is to:
- understand the degree of processing
- recognise when nutrients have been removed
- identify when additives replace real ingredients
- choose foods that support health rather than undermine it
Future Nx's will provide a clear, simple, evidence‑based way to make these decisions, except for tinned products, which can be evaluated once opened.
