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.

  • E322 Lecithins Lecithins are fatty substances extracted mostly from soybeans, sunflower seeds or eggs, used as emulsifiers to keep fat and water mixed, for example in chocolate.
  • E422 Glycerol Glycerol is a sweet-tasting liquid used to keep products moist and soft.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.

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.

  • Dextrose Dextrose is pure glucose crystallised from starch-derived syrup.
  • Glucose Glucose, usually listed as glucose syrup, is cheap, keeps products moist and stops sugar from crystallising.
  • Lactose Lactose is milk sugar, crystallised industrially from whey, a by-product of cheese making.
  • Fructose Fructose is the sugar found naturally in fruit and honey, but as an ingredient it is refined industrially, mostly from corn starch.
7 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.

  • Honey Honey, used as a sweetener.
  • Salt Salt, added for taste and preservation.
  • Sugar Sugar refined from sugar cane or beet.
  • Vegetable fat Vegetable fats are oils that are solid at room temperature, such as palm or coconut fat.
  • Vegetable oil Vegetable oils are pressed or extracted from seeds, nuts and fruits.
  • Sweet snacks Products in the category "Sweet snacks" are at least group 3.
  • Milk powder Milk powder is milk with the water evaporated off: a preserved form of a whole food rather than an industrial extract.
