Signal NOVA classification supplies the definition driving the ultra-processed debate

Summary

The Nutrition for Healthspan Initiative traces much of the ultra-processed food debate to the NOVA classification system. NOVA sorts foods according to how much industrial processing they have undergone. Under this approach, ultra-processed foods are typically marked by ingredients that home cooks rarely use, such as emulsifiers, flavour enhancers, stabilisers, colourings and synthetic preservatives. These additives help manufacturers achieve consistency, long shelf life and distribution at scale. They are now under growing scrutiny as consumers look for foods that stay closer to their original farm form. The Initiative presents NOVA as the definitional basis on which the wider backlash rests.
