Ultra-processed foods: why beware?

Ultra-processed foods (UPFs) now account for almost 65% of the food products available in supermarkets. Yet they are a recent phenomenon: 50 years ago, they hardly existed at all.

The food industry first developed these products in the 1970s and 1980s to improve food safety and preservation. But over time, these products have become tastier and more attractive... at the cost of profound transformations.

How are they made?

TUEs do not come directly from nature. Originally, they are raw raw materials (wheat, milk, meat, vegetables) that are transformed by complex industrial processes: fractionation, blow-moulding, cooking-extrusion, hydrogenation... These techniques modify the structure of the food, causing it to lose some of its nutritional qualities.

Various additives are then added to improve texture, taste or shelf life:

How to recognize them?

Ultra-processed foods are characterized by their long lists of ingredients, often incomprehensible to the consumer. Here's a simple guide:

Practical tip: the more ingredients a product contains that you can't find in your kitchen, the more likely it is to be ultra-processed!

Why are they singled out?

TUEs are regularly criticized for their poor nutritional quality. On average, they contain :

The problem lies not only in their composition, but also in the way they are processed. Their modified texture and accentuated flavors encourage over-consumption, reducing the sensation of satiety and speeding up digestion.

What are the impacts on health and the environment?

Proven health risks. Studies have shown that excessive consumption of TUE is associated with an increased risk of disease:

  • Obesity and overweight: their low satiety effect pushes us to eat more.
  • Diabetes and cardiovascular disease: their high sugar and saturated fat content promotes these pathologies.
  • Disturbance of the intestinal microbiota: certain additives, such as emulsifiers, could unbalance our intestinal flora.
  • A significant environmental impact

TUEs not only damage our health, they also affect our planet:

  • Single-use plastic packaging
  • Intensive use of natural resources
  • High carbon footprint linked to transport and processing

How can we limit their consumption?

Good news: it's easy to reduce your consumption of ultra-processed foods!

In a nutshell:

Ultra-processed foods are ubiquitous in our diet, but their effects on health and the environment call for caution. By choosing a more natural diet and cooking more, we can easily reduce their impact.
