Keto-style carbohydrate trackers
If you use soya drink in tea, cereal or recipes, the carbohydrate figure for your actual portion matters more than a front-of-pack sugar claim.
Who needs to check the details?
Households shopping for larger quantities
If a four-pint milk bottle is your usual shop, compare the total volume of soya cartons with the cupboard space they need unopened and the time allowed to use each carton after opening.
Dairy-free shoppers checking fortification
If you want particular added nutrients, read the exact carton’s label for calcium, iodine and vitamins rather than assuming every unsweetened soya drink has the same ingredients.
What should you compare?
Start with the nutrition panel and the volume you will actually use. Then decide whether the cartons’ storage instructions work for your household.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Compare the full carbohydrate figure per 100ml, not just “of which sugars”. Work out the amount in the portion you will use; check the measurement basis if a label gives values per 100g instead. | I might use only a splash in a drink or a larger amount with cereal, so I need the figure for my own portion. |
| Pack volume | Check the stated litres and whether the product is one container or several cartons. Four pints is approximately 2.27L; an 8 × 1L pack is a different format and quantity. | A larger shop would be convenient, but I do not want to mistake a dairy-milk four-pint listing for a soya drink. |
| Storage | Distinguish unopened long-life cartons from chilled products. Check the exact carton’s refrigeration instructions and use-within period after opening. | If I buy several cartons, I want to open them at a pace that fits how much the household drinks. |
| Fortification | Read the ingredient and nutrition information for any calcium, iodine or vitamins you are looking for; declarations differ between products. | When replacing a dairy drink, I want to know what the particular soya carton contains. |
| Allergens | Check the soya declaration and any additional allergy warnings on the exact pack, including nut-related warnings where relevant. | Someone in my household needs the allergy information for the product we will actually use. |
Shopping mistakes to avoid
-
Assuming “four pints” identifies a soya drink
Sainsbury’s four-pint listings cited here are for dairy milk, while the named soya-drink examples are 1L cartons. Pack size alone does not identify the drink or its carbohydrate content.
Check both the product type and stated volume. If you choose several cartons instead, plan where unopened and opened cartons will go.
-
Checking sugars but overlooking total carbohydrate
“Unsweetened” and “no sugar” do not give the full carbohydrate figure. For example, Tesco Groceries lists 1.1g carbohydrate per 100ml for its Longlife Soya Drink Unsweetened.
Use the carbohydrate line and your intended serving size when comparing cartons.
-
Opening several long-life cartons together
Long-life storage before opening does not replace the instructions for an opened carton. The product listings give different refrigerated use-within periods.
Check each pack and open cartons one at a time unless they will be used within their stated period.
Opening more than the household can use may mean discarding some drink.

Treating a retail comparison as a medical diet plan
A nutrition-panel comparison cannot determine whether a product fits an individually prescribed ketogenic diet. The British Dietetic Association advises people with a medical condition to seek dietitian advice.
If your diet is medically prescribed, discuss product changes with the clinician or dietitian responsible for your care.
Brand and retailer products to compare
These examples show why the exact product label matters: pack format, declared carbohydrate and fortification are not identical across soya drinks.
Alpro
Alpro has chilled and long-life no-sugar soya drinks in 1L cartons.
- Waitrose & Partners lists 0g carbohydrate and 0g sugars per 100ml for both its Alpro No Sugar Chilled and Alpro Organic No Sugar Long Life products.
- The chilled carton needs refrigeration; Waitrose & Partners instructs shoppers to refrigerate both products after opening and use them within five days.
Tesco
Tesco Longlife Soya Drink Unsweetened is a 1L own-label carton.
- Tesco Groceries lists 1.1g carbohydrate per 100ml and declares calcium and iodine.
- It is not a single four-pint container. Check the carton’s current nutrition information when shopping.
Sainsbury’s
Sainsbury’s lists its chilled Unsweetened Soya Drink and an Alpro No Sugar Long Life drink, both in 1L cartons.
- The Sainsbury’s own-label listing declares added calcium, iodine, vitamin D and vitamin B12.
- Sainsbury’s says to keep its chilled own-label carton refrigerated and use it within three days of opening.
Asda
JUST ESSENTIALS by ASDA Unsweetened Soya Drink is a 1L carton.
- ASDA Groceries declares less than 0.5g carbohydrate per 100ml.
- ASDA says to refrigerate the drink after opening and consume it within four days.
M&S
M&S Unsweetened Soya Drink comes in a 1L carton with declared calcium, iodine and vitamins D and B12.
- Its nutrition information gives a carbohydrate figure that can be checked against the portion used.
- Marks & Spencer says the product is not suitable for people with a nut allergy and should be used within three days of opening.
Waitrose
Waitrose Essential Unsweetened Soya Drink is a 1L long-life carton; Waitrose also lists other soya-drink brands.
- Waitrose & Partners declares 0.8g carbohydrate per 100ml and lists added calcium, iodine and vitamins for its Essential product.
- Its instructions say to refrigerate the carton below 5°C after opening and consume it within three days.
Joybuy option for a larger shop
This multi-carton soya drink pack is an option to consider when buying a larger quantity. It is eight separate 1L cartons, not one four-pint bottle; check the exact pack label for nutrition and storage instructions before deciding whether it suits your use.

Alpro Soya No Sugars Long Life Drink, 8 × 1L
Eight 1L cartons offer a multi-carton format for a larger shop rather than a single four-pint bottle. Check the exact cartons’ carbohydrate figures and after-opening instructions against how much you expect to use.
Questions about soya drink and pack size
Does “no sugar” mean a soya drink fits my carbohydrate plan?
Not on its own: check total carbohydrate and calculate it for the amount you will drink. Waitrose & Partners lists 0g carbohydrate per 100ml for its Alpro Organic No Sugar Long Life and Alpro No Sugar Chilled products, while Tesco Groceries lists 1.1g per 100ml for Tesco Longlife Soya Drink Unsweetened. Check each current carton before using those figures.
Is a four-pint milk listing necessarily a soya drink?
No. Sainsbury’s four-pint examples cited here are dairy milk; its named unsweetened soya drink is a 1L carton. Check the product type, volume and nutrition panel on the exact item rather than assuming the same bottle size exists for soya drink.
How should I plan a purchase of several cartons?
Check where unopened cartons can be stored, then follow each carton’s refrigerated use-within instruction after opening. ASDA Groceries specifies four days for its JUST ESSENTIALS unsweetened soya drink, while Waitrose & Partners specifies three days for its Essential Unsweetened Soya Drink; open cartons at a pace that fits household use.
Can a soya drink label determine suitability for a prescribed ketogenic diet?
No. A label can provide carbohydrate and allergen information, but it cannot replace an individual medical diet plan. The British Dietetic Association advises people with a medical condition to seek dietitian advice; discuss changes to a prescribed diet with the clinician or dietitian responsible for it.
