Is popcorn ultra-processed?

Kernels are group 1. Most bags are group 4.

It depends entirely on how far along the process you buy it, which makes popcorn a neat demonstration of what NOVA is actually measuring.

  • Kernels in a bag: group 1. Dried maize, nothing added.
  • Popped at home with oil and salt: group 3.
  • Ready-to-eat plain or lightly salted: usually group 3.
  • Sweet, salted-caramel or flavoured bags: group 4, from flavourings and glucose syrups.
  • Microwave popcorn: usually group 4, from the flavourings and fats in the bag.

The same maize can therefore be group 1, group 3 or group 4 depending only on what was done to it and by whom, which is the classification's whole proposition stated in a single ingredient.

Working this out from a receipt is harder than from a packet, because a till prints about twenty characters of product name and no ingredients list. That is the problem Bagged exists to solve, and how a receipt is structured explains why it is the hard part.

Common questions

Is microwave popcorn ultra-processed?
Usually. The bag contains fats and flavourings alongside the kernels, and those are group 4 markers even though the maize itself is group 1.

One photo of a receipt answers this for your own shopping.

Bagged reads every line and reports what share of your food spend was ultra-processed, and which items it was.
