What makes it ultra-processed

Cosmetic additives

Added to change how the food looks, feels or tastes, not to keep it safe. A hallmark of ultra-processed food.

Substances rarely used in home kitchens

Refined or extracted in factories, such as syrups made from starch or isolated proteins. The other hallmark of ultra-processed food.

  • Gluten Wheat gluten, sold as "vital wheat gluten", is the protein washed out of wheat flour.
4 ingredients that would only make it processed

Kitchen staples like sugar, salt and oil. On their own they make a food processed, not ultra-processed.

  • Salt Salt, added for taste and preservation.
  • Sugar Sugar refined from sugar cane or beet.
  • Vegetable oil Vegetable oils are pressed or extracted from seeds, nuts and fruits.
  • Sandwiches Products in the category "Sandwiches" are at least group 3.
