Sugar-conscious curry cooks
If you make the sauce separately, the tuna’s per-100g sugars declaration helps you assess what the fish contributes. Check the sauce ingredients separately.
Who this choice matters to
Quick midweek cooks
If preparation time matters, compare chunks with larger pieces and check whether a tin needs draining. Pack size and instructions for storing leftovers may also affect your choice.
Sourcing-focused shoppers
If fishing method or certification matters to you, look for a statement on the exact product. A sourcing statement does not establish its sugars or salt value.
What to check when buying
Compare the tuna’s nutrition declaration separately from the curry sauce, then decide which format suits the way you will cook and serve it.
| Concern | Buying check | Who it matters to |
|---|---|---|
| Sugars in the tuna | Read “of which sugars” per 100g on the exact tin, noting whether the figure is for drained tuna. | If I make the sauce separately, I want to know what sugar the tuna itself adds; about 50% of consumers put that label check first. |
| Texture and preparation | Choose between chunks and larger pieces; check drained weight and whether draining is required. | When dinner needs little preparation, I want a format that works in my curry; about 30% of consumers make texture and convenience their primary concern. |
| Sourcing information | Look for a fishing-method or certification statement for the exact product, then check its nutrition panel separately. | I want to know how the tuna in this tin was sourced before choosing it; that is the leading concern for about 20% of consumers. |
Common buying mistakes
-
Taking “reduced sugar” to mean zero sugar
“Reduced” describes a comparison, not a zero-sugar value. The British Nutrition Foundation explains that a “low sugar” claim for solid food can apply at up to 5g sugars per 100g.
For the tuna’s contribution to your curry, compare the “of which sugars” figures on the exact tins. Check the sauce ingredients separately.
-
Assuming spring-water tuna is low in salt
The Joybuy listing for John West Tuna Chunks in Springwater 4 x 125g declares 0g sugars but 0.80g salt per 100g drained.
Read both lines of the nutrition panel, particularly if your sauce also contains salty ingredients.
-
Choosing a multipack by tin size alone
Tin size and drained weight describe different quantities. Whether the tuna needs draining also affects preparation.
Compare drained weights when planning how much fish to use, and choose chunks for stirring through or larger pieces when you want them to remain visible.
-
Leaving unused tuna in an opened tin
Tesco’s instructions for its Tuna Chunks in Spring Water 4 x 160g call for transferring unused contents to a non-metallic container, covering and refrigerating them.
Follow the instructions on your pack; Tesco specifies using that product within two days of opening.
Brands to consider for this choice
John West
A spring-water option with a stated sugars value for the specific 4 x 125g multipack listed by Joybuy.
- That listing declares 0g sugars and 0.80g salt per 100g drained.
- Check other John West variants individually, particularly tins with different packing liquids or dressings.
Princes
Sainsbury’s lists Princes spring-water chunks and a Drained & Ready to Use tuna steak format.
- The steak format is described by Sainsbury’s as already drained.
- Check sugars and salt on the particular pack rather than inferring them from its format.
Tesco
Tesco lists own-label tuna chunks in spring water in several pack formats.
- Pack choices let you compare the quantity needed for one curry with repeat use.
- Read the current tin for its sugars, salt, drained weight and storage instructions.
Sainsbury's
Sainsbury’s describes its own-label 145g spring-water tuna as pole-and-line caught and from an MSC-certified fishery.
- Those sourcing statements relate to the specified product.
- Check its nutrition declaration separately; sourcing claims do not establish sugars or salt.
M&S
M&S describes its spring-water chunks as pole-and-line caught under its Forever Fish policy and lists an already-drained steak format.
- The two formats offer a choice between chunks and larger ready-drained pieces.
- Check nutrition and sourcing information for the exact format you choose.

SAJO Light Standard Canned Tuna 100g

Questions about tuna for curry
Does “reduced sugar” mean the tuna has no sugar?
No. “Reduced” is comparative, while the British Nutrition Foundation says a “low sugar” claim for solid food can apply at up to 5g sugars per 100g. To assess the tuna you will add to a curry, read the exact tin’s “of which sugars” value.
Is tuna in spring water always the lowest-sugar choice?
Not necessarily. Joybuy’s John West Tuna Chunks in Springwater 4 x 125g listing declares 0g sugars per 100g drained, but the packing liquid alone does not establish another product’s value. Compare the nutrition panels of the tins you are choosing between.
Should I check salt when the tuna declares 0g sugars?
Yes; the two values are separate. Joybuy’s John West Tuna Chunks in Springwater 4 x 125g listing declares 0g sugars and 0.80g salt per 100g drained. Check the salt on your chosen tin alongside other ingredients in the curry.
How should I keep tuna left over from an opened tin?
Follow your tin’s storage instructions. For its Tuna Chunks in Spring Water 4 x 160g, Tesco instructs shoppers to transfer unused contents to a covered non-metallic container, refrigerate them and use them within two days.
