Who needs to check what?

People counting carbohydrate

A stated serving makes it easier to compare a mint with the amount you plan to eat. Tesco lists 4.3g carbohydrate per three Polo Sugar Free mints; a sugar-free label alone does not give you that portion figure.

People carrying mints during the day

Pack size and serving guidance answer different questions. Tesco lists Trebor Mighties in a 12.5g pack and Polo Sugar Free in a 33.4g roll, but the smaller pack does not establish the size or carbohydrate content of each mint.

People checking sweetener ingredients

Read the ingredient list and pack warnings if particular sweeteners matter to you. Tesco lists sorbitol in Polo Sugar Free and sorbitol with sucralose in Trebor Mighties; UK government food-labelling guidance requires a laxative-effect warning when a food contains more than 10% polyols.

What matters when choosing mini mints?

Start with the carbohydrate declaration for a usable portion, then decide whether a smaller pack or a stated mint count helps you manage that portion.

Priority What to check Your needs
Carbohydrate per portion Compare the label’s serving with the number of mints you expect to eat. Tesco lists 4.3g carbohydrate per three Polo Sugar Free mints; its Trebor Mighties listing gives 97g available carbohydrate per 100g. I want to account for the mints I actually eat, rather than assume that sugar-free means carbohydrate-free.
Pack and serving format Check net pack weight separately from any stated mint count or serving. Tesco lists a 12.5g Trebor Mighties pack, a 33.4g Polo roll and a Polo four-pack containing four 33.4g rolls. A smaller pack is easier for me to carry, but a stated three-mint serving may be more useful when I count portions. Pack weight does not tell me the size of each mint.
Sugars and ingredients Check the sugars line and the exact variant’s ingredients. Sainsbury’s lists 2.3g sugars per 2.4g portion of standard Trebor Extra Strong, with sugar, glucose syrup and starch in its ingredients. I want to distinguish a sugar-free variant from a conventional mint with a similar brand name or flavour description.
Sweetener warnings Read the current ingredients and warnings, particularly for polyols. UK government food-labelling guidance specifies a laxative-effect warning for foods containing more than 10% polyols. Before choosing a sugar-free mint, I want to know which sweeteners it contains and whether a pack warning is relevant to me.

Mistakes to avoid

  • Treating “sugar-free” as “zero carbohydrate”

    Tesco lists 4.3g carbohydrate per three Polo Sugar Free mints and 97g available carbohydrate per 100g of Trebor Mighties, despite the latter listing 0g sugars.

    Check the declared carbohydrate and work from the portion you expect to eat, not the front-of-pack sugar claim alone.

  • Choosing a familiar mint name without checking the variant

    Standard Trebor Extra Strong is sugar-sweetened: Sainsbury’s lists sugar, glucose syrup and starch, and 2.3g sugars per 2.4g portion. “Extra Strong” describes the flavour, not its carbohydrate content.

    Check the full product name, ingredients and nutrition label of the exact pack.

  • Assuming a multipack changes the serving

    Tesco lists approximately 28 three-mint servings in the Polo Sugar Free four-pack, with 4.3g carbohydrate per stated serving. Having more rolls to hand does not change that serving figure.

    If you want to carry a limited quantity, take one roll rather than treating the multipack as a single on-the-go portion.

  • Overlooking sweetener warnings

    UK government guidance requires a laxative-effect warning for foods containing more than 10% polyols. Tesco also lists a phenylalanine-source warning for Smint Peppermint, which contains aspartame.

    Read the ingredients and warnings on the current pack before choosing a product, especially if a listed sweetener matters to you.

Frequently asked questions

Are sugar-free mints automatically suitable for keto portion planning?

No. Sugar-free describes sugars, not the total carbohydrate declared for a portion. Tesco lists 4.3g carbohydrate per three Polo Sugar Free mints and 97g available carbohydrate per 100g of Trebor Mighties; compare the amount you expect to eat with your own plan.

Which of these compact mint packs is smallest?

Among the Tesco-listed examples discussed here, Trebor Mighties has the smallest net pack weight at 12.5g. A Polo Sugar Free roll is 33.4g, and its four-pack contains four 33.4g rolls. Pack weight does not establish the size of an individual mint.

Why can a sugar-free mint still list carbohydrate?

The sugar-free products here use sweeteners including sorbitol, and their carbohydrate declarations are not zero. Tesco lists 97g available carbohydrate and 97g sugar alcohols per 100g of Trebor Mighties. Use the nutrition declaration for the product and portion you choose.

What warning should I check on mints containing polyols?

UK government food-labelling guidance requires foods containing more than 10% polyols to carry a warning that excessive consumption may cause a laxative effect. Read the current pack’s ingredients and warnings, particularly if you expect to eat repeated portions.

Is standard Trebor Extra Strong the same choice as sugar-free Mighties?

No. Sainsbury’s lists sugar, glucose syrup and starch in standard Trebor Extra Strong peppermint mints, with 2.3g sugars per 2.4g portion. Tesco lists Mighties as sugar-free, but it still declares available carbohydrate, so check the exact variant and its portion information.
