Who needs these checks?

The same carton can raise different questions depending on how it will be used and who will drink it.

Adults managing diabetes

If you use a soya drink regularly, its total carbohydrate and your usual portion are more useful for carbohydrate planning than the sugars line alone. Diabetes UK advises checking total carbohydrate on food labels.

Older adults replacing dairy

If soya drink takes the place of dairy in an everyday routine, check the particular carton for calcium fortification. Being older does not, by itself, establish a need for a separate diabetes-specific soya formulation.

Dairy-free households

For tea, cereal, porridge or cooking, compare the drink you would actually use with your household’s allergen needs and opened-carton storage instructions, as well as its carbohydrate and fortification labels.

What to check on a soya drink

Start with comparable nutrition figures for ready-to-pour drinks. If considering a powder, check the amount of dry product used before comparing a prepared serving with a carton.

Priority What to check When it matters to me
Total carbohydrate Read total carbohydrate per 100ml, not just sugars or traffic-light colours. Work out the amount for your usual pour; follow your agreed method if you count carbohydrate for insulin. I use soya drink in cereal or drinks and need to account for the amount I actually pour. A “no sugars” name does not answer that question on its own.
Fortification Check the current carton for calcium. If relevant to how the drink replaces dairy in your diet, also check the listed iodine and vitamins B12 and D. The UK Government’s July 2025 assessment says plant-based drinks labelled organic in the UK cannot be fortified with nutrients. When soya drink regularly replaces dairy for me, I want to know what is added to this particular product rather than assuming all unsweetened cartons are alike.
Ingredients and storage Read the soya allergen declaration and any precautionary allergen wording. Check whether the carton is chilled or long-life and follow its instructions after opening. Someone in my household has an allergy, or we use a carton over several days. I need the current pack’s ingredients and storage directions.
Drink format For powder, establish whether nutrition is stated per 100g of dry powder or for the prepared drink. Use the specified powder quantity when working out a serving. I’m considering a powder for cupboard storage, but I want to compare the drink I would prepare with a ready-to-pour carton on a meaningful basis.

Common shopping mistakes

  • Treating “no sugars” as the whole carbohydrate check

    Diabetes UK advises reading total carbohydrate, which includes more than sugars. Front-of-pack traffic-light colours do not give that total.

    Compare total carbohydrate per 100ml, then use the amount you actually pour. If you count carbohydrate for insulin, follow the approach agreed with your diabetes healthcare team.

  • Assuming every soya drink is fortified alike

    Fortification differs between products. The UK Government’s July 2025 assessment says plant-based drinks labelled organic in the UK cannot be fortified with nutrients, so an organic carton should not be assumed to match a fortified dairy alternative.

    If the drink routinely replaces dairy, follow Diabetes UK’s advice to check for calcium fortification, then read the carton for any other nutrients that matter to your choice.

  • Comparing dry powder directly with a carton

    The Joybuy listing for YON HO Sugar-Free Soy Milk Powder gives 63.3g carbohydrate per 100g of powder. That dry-weight figure is not a per-100ml value for a prepared drink.

    Check the preparation directions and the quantity of powder used before working out the carbohydrate in your serving.

  • Overlooking allergens because a drink is plant-based

    Soya itself is an allergen, and some product labels carry additional precautionary wording. A suitable nutrition panel does not establish allergy suitability.

    Check the current ingredients and allergen statement for the person who will drink it, particularly if the recipe or packaging has changed.

Brand and product-line references

These label examples describe particular drinks, not every product sold under each brand. Compare figures on the same per-100ml or per-100g basis and check the pack you buy.

Alpro

Sainsbury’s listing for Alpro Soya No Sugars describes a long-life soya drink with added calcium, iodine and vitamins B2, B12 and D2.

  • The retailer describes this particular drink as having no sugars.
  • The claim does not replace checking total carbohydrate and the portion poured on the current carton.

Sainsbury’s

Sainsbury’s Unsweetened Soya Drink 1L is a labelled option for comparing a ready-to-pour drink.

  • Sainsbury’s lists 1.2g carbohydrate and less than 0.5g sugars per 100ml, with 120mg calcium and 22.5µg iodine per 100ml.
  • Check the current carton’s ingredients, fortification and instructions after opening before making it a regular dairy alternative.

Waitrose Essential

Waitrose Essential Unsweetened Soya Drink is another ready-to-pour product with listed nutrition and fortification.

  • Waitrose & Partners lists 0.8g carbohydrate and 0g sugars per 100ml, plus added calcium, vitamin D, B12, B2 and iodine.
  • Use the label on the carton purchased to confirm its recipe and storage directions.

M&S Plant Kitchen

M&S Plant Kitchen Unsweetened Soya Drink has a nutrition declaration measured per 100g rather than per 100ml.

  • Marks & Spencer lists 1.5g carbohydrate and 0.4g sugars per 100g, with calcium, iodine, vitamin D and B12 fortification.
  • Do not treat its per-100g figures as directly identical to another drink’s per-100ml figures; check the current allergen statement too.

Joybuy soya drink option

This long-life, ready-to-pour Alpro option is relevant if a “no sugars” soya drink suits your shopping routine. Its name alone cannot establish how its carbohydrate or fortification fits your needs.

Alpro Soya No Sugars Long Life Drink, 8 x 1L

Alpro Soya No Sugars Long Life Drink, 8 x 1L

A long-life soya drink sold as an 8 x 1L pack. For carbohydrate planning, check total carbohydrate on the current carton and use the amount you actually pour. If it replaces dairy, confirm the fortification you need on that carton; soya allergen information also matters.

Questions about choosing soya drink

Is “no sugars” soya drink automatically suitable for someone managing diabetes?

No: the claim does not tell you the carbohydrate in your usual serving. Diabetes UK advises checking total carbohydrate, including when carbohydrate counting forms part of an individual insulin plan.

What should I check if soya drink replaces dairy?

Diabetes UK advises choosing an unsweetened dairy alternative fortified with calcium. Check the particular carton for calcium and, where relevant to your wider diet, its listed iodine and vitamins B12 and D; fortification varies between drinks.

Will an organic soya drink be fortified?

Do not assume it will. The UK Government’s July 2025 assessment says plant-based drinks labelled organic in the UK cannot be fortified with nutrients. If you choose one as a regular dairy replacement, consider how its unfortified nutrient profile fits the rest of your diet.

Can someone with a soya allergy drink soya milk?

No: soya drinks contain soya. Read the current allergen statement as well, because additional precautionary wording may matter for someone with another food allergy.

How do I compare soya powder with a ready-to-drink carton?

Check whether the powder’s nutrition is stated for the dry product or the prepared drink, then use the amount required for your serving. For example, Joybuy’s YON HO Sugar-Free Soy Milk Powder listing states 63.3g carbohydrate per 100g of powder; that figure cannot be compared directly with a carton’s per-100ml value.
