Is Gammon Ultra-Processed?
Mostly no — gammon is typically processed (NOVA 3), not ultra-processed
Most gammon is not ultra-processed. Plain gammon joints and steaks at Tesco typically score NOVA 3 (processed), containing pork, water, salt, and preservatives like sodium nitrite. However, some gammon products cross into NOVA 4 territory — boneless joints contain dextrose, an industrial sugar, while glazed gammon adds sugar syrups and treacle. Plain, unglazed gammon steaks are your cleanest option at NOVA 3.
Why Gammon scores NOVA 3 — Processed
Gammon is a cured pork product, and curing inherently places it in at least NOVA 3 (processed). The simplest gammon products — like Tesco Unsmoked Gammon Steaks — contain just four ingredients: pork (87%), water, salt, and preservatives (sodium nitrite, potassium nitrate). This is straightforward curing, the same process used for centuries.
The picture gets more complicated with boneless gammon joints. Tesco Smoked Boneless Gammon Joint contains dextrose — an industrial sugar used in the curing process. While the quantity is small, dextrose is an industrial additive that pushes the product towards NOVA 4 under strict interpretation. The unsmoked boneless version also contains dextrose.
Glazed gammon products add another layer of processing. Tesco 2 Gammon Steaks with BBQ Glaze has 16 ingredients including sugar, treacle, cornflour, colour (plain caramel), and smoked water. The Tesco Gammon Joint With Honey contains sugar, glucose syrup, and honey. These glazed products remain at NOVA 3 in our analysis because the additives are culinary (sugars, vinegar, spices) rather than industrial, but they represent a more processed end of the gammon spectrum.

What to look for when shopping
For the least-processed gammon, choose plain unsmoked gammon steaks or joints — these typically contain just pork, water, salt, and a preservative. Avoid boneless joints if possible, as these often include dextrose and stabilisers like pentasodium triphosphate. Skip pre-glazed gammon entirely and make your own glaze from honey or mustard at home.
