Who is choosing?

5K runners buying one item on the way

A small, portable purchase might be a mint for freshness or food for before the run. Decide which job you need it to do before picking up a mint roll.

Runners who prefer sugar-free mints

A sugar-free mint can fit a preference for breath freshness without choosing a sugared mint. It is still a separate decision from whether you need pre-run food.

What should you check?

Start with the purpose of the purchase: food before a run and a mint for freshness are not interchangeable. Then compare the serving you would actually have and read the current pack.

Priority What to check Your needs
Pre-run food Decide whether you need a snack at all. If you do, consider a carbohydrate-containing food and a portion you tolerate; the British Dietetic Association advises including carbohydrate foods as part of sport and exercise nutrition. If I am buying one item because I need food before my 5K, I want it to serve that purpose rather than relying on a breath mint.
Serving size Compare energy and carbohydrate for the amount you would eat. Tesco lists 18 kcal and 4.4 g carbohydrate per three POLO Original mints; Sainsbury’s lists 9 kcal and 2.4 g available carbohydrate per 2.4 g serving of Trebor Extra Strong Peppermint. I want to know what a realistic portion contributes, not assume that a whole roll and the labelled serving are the same thing.
Sugared or sugar-free Check sugars and the sweetener in the ingredients. Tesco lists 4.3 g sugars per three POLO Original mints; its POLO Sugar Free listing names sorbitol and lists less than 0.5 g sugars per three mints. For breath freshness, I can choose the type of mint I prefer without treating its sugar status as a fuelling benefit.
Pack wording Read the current ingredients, allergen information and sweetener wording. GOV.UK specifies an excessive-consumption laxative-effect warning for foods containing more than 10% polyols. Before taking an unfamiliar mint to a run, I want to check its ingredients and any warning on the pack in my hand.

What is easy to overlook?

  • Using a mint roll as the planned pre-run snack

    The servings listed by Tesco for POLO Original and Sainsbury’s for Trebor Extra Strong Peppermint contain small amounts of energy and carbohydrate. A mint bought for freshness does not take the place of deciding whether you need food before your 5K.

    Make the food decision first. If you need a snack, choose a carbohydrate-containing food you tolerate, and take a mint only if you also want one.

  • Reading “sugar-free” as a fuelling claim

    Tesco lists POLO Sugar Free as containing sorbitol, with less than 0.5 g sugars but 4.3 g carbohydrate per three mints. Those label values describe a mint serving; they do not establish it as a pre-run snack.

    Use the nutrition panel and ingredients to choose between mint types, then consider any need for pre-run food separately.

  • Overlooking sweeteners on an unfamiliar pack

    A mint containing polyols may carry a warning relevant to how much you eat. GOV.UK specifies an excessive-consumption laxative-effect warning when a food contains more than 10% polyols.

    Read the current pack for its ingredients and warnings. If you have not tried a product before exercise, avoid making the run your first occasion to use it.

Questions about mints before a 5K

Can mints be my only food before a 5K?

Do not rely on a mint serving as your planned pre-run food if you need a snack. Tesco lists 18 kcal and 4.4 g carbohydrate per three POLO Original mints, and Sainsbury’s lists 9 kcal and 2.4 g available carbohydrate per 2.4 g serving of Trebor Extra Strong Peppermint. The British Dietetic Association advises including carbohydrate foods as part of sport and exercise nutrition; choose a food and portion you tolerate if you need to eat before running.

Should I choose sugared or sugar-free mints before a run?

Choose according to your preference for the mint, not an assumed 5K fuelling advantage. Tesco lists 4.3 g sugars per three POLO Original mints, while its POLO Sugar Free listing names sorbitol and gives less than 0.5 g sugars per three mints. Decide separately whether you need pre-run food.

What should I read on a mint pack?

Check the current pack for ingredients, allergens, nutrition, sweeteners and any warnings that apply. GOV.UK specifies an excessive-consumption laxative-effect warning for foods containing more than 10% polyols. Use the physical pack when deciding whether an unfamiliar mint suits you before a run.

Is a single roll the same as one serving?

Not necessarily: compare the amount you expect to eat with the serving stated on the label. Tesco gives POLO Original nutrition per three mints, while Sainsbury’s gives Trebor Extra Strong Peppermint nutrition per 2.4 g serving. Neither figure describes a whole roll unless the pack says so.
