Ultra-Processed Food in Australia: What It Actually Is and How Much You're Eating
By Neer, NutriThrive Truganina · Last updated: 7 Jul 2026
"Ultra-processed food" is one of those terms that’s been everywhere in health media for the past few years, but the actual definition is fuzzier in most people’s heads than it should be. Bread? Processed. Canned tomatoes? Processed. Vegemite? Processed. So what’s the difference between processed and ultra-processed — and why does it matter?
The NOVA classification: a more useful way to think about food
Most food on earth has been processed in some way. The question isn’t whether food has been touched since it left the ground — it’s what kind of processing, and what it does to the food.
The NOVA classification system, developed by researchers at the University of São Paulo, divides food into four groups based on the degree and purpose of processing:
Group 1: Unprocessed or minimally processed foods. Fruits, vegetables, meat, eggs, milk, legumes, nuts. The food itself, with nothing significant added or removed.
Group 2: Processed culinary ingredients. Oils, butter, flour, salt, sugar. Things used to prepare food, not eaten alone.
Group 3: Processed foods. Tinned fish, cured meats, cheese, freshly baked bread, preserves. Real food that has been preserved, fermented, or otherwise modified, typically with a short ingredient list.
Group 4: Ultra-processed foods. Industrial formulations made largely from food-derived substances plus additives. The ingredient list is long, contains things you wouldn’t find in a home kitchen (emulsifiers like polysorbate 80, flavour enhancers like disodium inosinate), and the original whole food is essentially unrecognisable.
The tell-tale ingredient list
The fastest way to identify ultra-processed food in the supermarket is to look at the ingredient list rather than the nutrition panel. If the list is long, contains additives you can’t picture in a kitchen, or if the first few ingredients are refined starches, sugar, and oils with no whole food present, you’re looking at an ultra-processed product.
A loaf of sourdough bread might have four ingredients. An ultra-processed bread product has twenty, including dough conditioners, emulsifiers, and artificial flavours. Same category of food, completely different product.
How much are Australians actually eating?
More than most people think. National nutrition data shows Australians get roughly 35-40% of their daily calories from ultra-processed food. For children and teenagers, some analyses put the figure above 50% of daily energy intake.
This isn’t mostly about fast food, either. Breakfast cereals, flavoured yoghurts, packaged muesli bars, protein bars, and instant noodles are all ultra-processed. The category shows up in the foods many Australians think of as reasonable or even healthy choices.
What the research says about health outcomes
The evidence on ultra-processed foods has strengthened considerably in recent years:
A 2024 study involving nearly 10 million people found that high ultra-processed food consumption was associated with a 50% increased risk of cardiovascular disease-related death and elevated risk across 32 different adverse health outcomes. Australian women with higher ultra-processed food intake were found to be 39% more likely to have high blood pressure in a separate 2024 study.
A June 2026 study from Monash University — using Australian data specifically — found that ultra-processed food consumption was associated with poorer cognitive function even in generally healthy people who didn’t otherwise appear to eat an unhealthy diet. The finding suggests the effects may operate independently of the obvious nutritional downsides like excess sugar and fat.
What to actually do with this information
The goal isn’t to eat zero ultra-processed food — that’s an unrealistic standard for most people, and the stress of trying to achieve it probably does its own harm. The more useful framing is crowding out rather than cutting out: when you consistently eat more whole foods, legumes, vegetables, and minimally processed foods, the proportion of ultra-processed food in your diet naturally drops without requiring vigilance over every purchase.
Cooking more at home, even simply, is the highest-leverage habit. Most home-cooked food, however basic, lands in Group 3 or lower on the NOVA scale.
FAQ
What counts as ultra-processed?
Industrial formulations with long ingredient lists, food-derived additives, and little to no whole food present.
How much do Australians eat?
Roughly 35-40% of daily calories on average. Higher for children.
Is it actually bad?
Evidence is increasingly strong — associations with cardiovascular disease, blood pressure, cognitive function, and obesity.
