Nutritionist explains how ultra-processed foods differ from whole ingredients
A nutritionist at Deakin Institute for Physical Activity and Nutrition discusses the definition of ultra-processed foods and their role in modern diets.
Defining ultra-processed food items
Dr Priscila Machado describes these products as branded commercial formulations made from cheap ingredients combined with additives. She notes that they often contain little to no whole food and include substances like protein isolates or emulsifiers. Looking at ingredient lists helps consumers spot these items because the components are usually unrecognizable or unused at home.
Cost and convenience factors
Many families believe these products are cheaper and less time-consuming than preparing meals from scratch. Convenience remains a major selling point for manufacturers who market these items to busy households. However, the actual cost difference depends on specific strategies families use to manage their consumption habits.
Health evidence and diet patterns
There is currently no strong evidence supporting a ranking of healthfulness among different types of ultra-processed foods. The bigger concern involves the proportion of these items within overall dietary patterns rather than individual food choices. In Australia, the UK and US, almost half or more of total energy consumption comes from these products.
