Overall verdict
A minimal 7-ingredient recipe. The tuna and ginger are NOVA 1, soy sauce and vinegar are NOVA 3. Honey is the only sugar source — used intentionally. MSG is NOVA 1 (a naturally occurring amino acid salt). The shop-bought teriyaki alternative tells a shockingly different story.

→| Lens | From Scratch | Shop-Bought | Delta |
|---|---|---|---|
| NOVA/UPF | NOVA 1–3, 0 UPF markers | Likely NOVA 4, 1 UPF marker (sodium benzoate preservative) | +1 UPF; preservative added to extend shelf life |
| Hidden Sugar | 1 known sugar (honey, controlled at 50g) | 1 alias (sugar) — but sugar is ingredient #1 | Sugar is the dominant ingredient, not a supporting flavour |
| Glucose Impact | Medium (honey in known quantity) | 80g sugar/100g, 84g carbs/100g | 80% sugar by weight — the highest in our entire swap set |
| Protein/Macros | 7 simple ingredients | 1.6g protein, 8.5g salt/100g, 348kcal, ammonia caramel colour | 8.5g salt/100g; ammonia caramel adds zero nutrition |
