Who is this choice for?

Keto-oriented shoppers who want organic soya milk

If you track carbohydrate intake, compare the total carbohydrate figure for the amount you actually use. The organic Alpro and Plenish drinks listed by ASDA Groceries and Joybuy declare different amounts per 100 ml, despite both listing 0 g sugars.

Shoppers who prefer a short ingredient list

Joybuy lists spring water and organic soya beans for Plenish Organic Unsweetened Soya Milk. If you also want added nutrients in a dairy alternative, compare fortification separately rather than assuming a short ingredient list provides it.

People checking allergens or dairy-alternative nutrients

Soya allergy rules out soya drinks. If you are choosing a drink for everyday tea, coffee or cereal, also check whether its label lists the added nutrients you want; the M&S Unsweetened Soya Drink listing, for example, identifies calcium, iodine, vitamin D and vitamin B12.

What should you check?

Start with the carton’s organic designation and total carbohydrate figure, then weigh ingredient simplicity against any fortification you want.

Priority What to check Your needs
Total carbohydrate Read total carbohydrate as well as sugars per 100 ml, then calculate it for the amount poured. ASDA Groceries lists Alpro Organic Soya No Sugars at 0.0 g carbohydrate and 0 g sugars per 100 ml; Joybuy lists Plenish Organic Unsweetened at 0.8 g and 0 g respectively. I count the carbohydrate in each serving, so a zero-sugars label alone does not answer whether the drink fits my plan.
Organic designation Check that the exact carton is labelled organic. UK guidance from the Department for Environment, Food & Rural Affairs says food may only be labelled organic when the applicable production and supplier certification requirements are met. Organic status matters to me; I would not treat vegan, plant-based or unsweetened wording as a substitute.
Ingredients and fortification Compare ingredient lists and added nutrients separately. Joybuy lists spring water and organic soya beans for Plenish; Marks & Spencer lists added calcium, iodine, vitamin D and vitamin B12 for its Unsweetened Soya Drink, which is not described as organic in that listing. Do I prefer a short organic ingredient list, or am I looking for specific added nutrients in a dairy alternative?
Allergens Read the allergen and cross-contact statements on the exact pack. The Food Standards Agency identifies soya as an allergen; Joybuy’s Plenish listing declares soya and says the drink may contain nuts. I need to rule out soya if I have a soya allergy, and check the nut statement if it is relevant to me.

Common buying mistakes

  • Reading “no sugars” as “no carbohydrate”

    Joybuy lists 0 g sugars but 0.8 g total carbohydrate per 100 ml for Plenish Organic Unsweetened Soya Milk. The two figures answer different questions when you are counting carbohydrate.

    Use the total carbohydrate line on the current carton and calculate it for your usual serving.

  • Assuming unsweetened means organic

    Unsweetened describes a different characteristic from organic production. UK organic labelling is subject to production and certification requirements, according to the Department for Environment, Food & Rural Affairs.

    If organic status is essential to your choice, check the designation on the exact carton rather than relying on other front-of-pack wording.

  • Assuming every soya drink has the same fortification

    A short ingredient list and added micronutrients are separate considerations. Joybuy lists water and organic soya beans for Plenish, while Marks & Spencer lists added calcium, iodine, vitamin D and vitamin B12 for its Unsweetened Soya Drink.

    Compare the current ingredient and nutrition panels if you want particular added nutrients, and check organic status and carbohydrate separately.

  • Overlooking allergies or a medically directed diet

    The Food Standards Agency identifies soya as an allergen, and the Plenish listing says it may contain nuts. Choosing a supermarket drink also does not replace guidance for a ketogenic diet used in connection with a medical condition.

    Avoid soya drinks if you have a soya allergy, and check relevant cross-contact statements. The British Dietetic Association advises people with a medical condition to seek advice from a dietitian before following a low-carbohydrate diet.

Brand and product-line references

These details concern the named drinks, not every soya product made by each brand.

Alpro

ASDA Groceries lists Alpro Organic Soya No Sugars Long Life Dairy Free Drink 1L as an organic UHT soya drink.

  • Its ASDA nutrition listing declares 0.0 g carbohydrate, 0 g sugars and 3.3 g protein per 100 ml.
  • Do not carry these figures over to Alpro Original or another variant; check the carton you select.

Plenish

Joybuy lists Plenish Organic Unsweetened Soya Milk 1L with spring water and organic soya beans as its ingredients.

  • The Joybuy listing declares 0.8 g carbohydrate, 0 g sugars and 3.2 g protein per 100 ml.
  • The same listing says it may contain nuts. Check the current pack if that statement affects your choice.

M&S Plant Kitchen

The M&S Unsweetened Soya Drink listing provides a comparison for shoppers considering fortification rather than making organic status their first requirement.

  • Marks & Spencer lists added calcium, iodine, vitamin D and vitamin B12 for this drink.
  • That listing does not describe the drink as organic and gives carbohydrate as 1.5 g per 100 g. Check its label against your own criteria rather than treating it as an organic alternative.

Frequently asked questions

Does “no added sugar” make organic soya milk suitable for keto?

No: check total carbohydrate and the amount you use. ASDA Groceries lists 0.0 g carbohydrate and 0 g sugars per 100 ml for Alpro Organic Soya No Sugars, while Joybuy lists 0.8 g carbohydrate and 0 g sugars per 100 ml for Plenish Organic Unsweetened. Whether a serving fits depends on your own carbohydrate plan.

How do I check that a soya drink is organic in the UK?

Look for the organic designation on the exact pack or current product listing. The Department for Environment, Food & Rural Affairs says food may only be labelled organic when applicable production and supplier certification requirements are met; words such as vegan or unsweetened do not establish organic status.

Should I choose a short ingredient list or a fortified drink?

Choose according to the attributes you need, then check carbohydrate and organic status separately. Joybuy lists just spring water and organic soya beans for Plenish Organic Unsweetened; Marks & Spencer lists added calcium, iodine, vitamin D and vitamin B12 for its Unsweetened Soya Drink, but does not describe that drink as organic in the listing.

Can I drink soya milk if I have a soya allergy?

No. The Food Standards Agency identifies soya as an allergen and a possible risk for people with a soya allergy. Check the exact pack for other relevant allergen statements too: Joybuy’s Plenish listing says it may contain nuts.

Is choosing a low-carbohydrate drink enough for a medically directed keto diet?

No. A drink’s nutrition panel tells you its declared carbohydrate contribution, not whether a diet meets medical requirements. The British Dietetic Association advises people with a medical condition to seek advice from a dietitian before following a low-carbohydrate diet.
