Families packing dairy-free school lunches
A long-life soya drink may suit a pupil who avoids dairy, provided they can have soya and the drink fits the school’s packed-lunch allergy arrangements.
Who is this for?
Families comparing sugars and taste
Unsweetened and sweetened cartons have different sugars figures. The label helps with the comparison, while the pupil’s preference matters before buying several cartons.
Households buying cartons in advance
Long-life cartons can be kept unopened for later use. Once a carton is opened, the household needs room to refrigerate it and a plan to finish it within the interval on its label.
What should you check before buying?
Start with the pupil’s and school’s allergy arrangements, then compare the carton’s sugars, added nutrients and storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Allergens and school rules | Read the current soya allergen statement. Ask the school how its packed-lunch allergy arrangements apply to drinks brought from home; Department for Education guidance addresses this for schools in England. | I need a drink that fits the pupil’s allergy plan and can be brought into school under its arrangements. Dairy-free does not mean soya-free. |
| Sugars and taste | Compare sugars per 100 ml on the exact varieties. Waitrose & Partners lists 0.0 g for Essential Unsweetened; Sainsbury’s lists 2.3 g for its Sweetened Soya Drink. | An unsweetened carton may fit my shopping preference, but I also need to know whether the pupil will drink it before stocking up. |
| Fortification | Check the ingredients and nutrition panel for declared calcium, iodine, vitamin D and B12; compare protein if relevant. The UK Office for Health Improvement and Disparities’ 2025 assessment notes that plant-based drinks vary considerably in nutrient content. | If soya drink regularly replaces dairy milk at home, I want to know what the particular carton contains rather than treating every variety alike. |
| Carton size and storage | Check the number and size of cartons, then the refrigeration instructions and use period after opening. Joybuy’s Alpro 8 x 1 L listing says to keep an opened carton at +1°C to +7°C and use it within 5 days. | A multipack helps me keep unopened cartons at home, but I need a workable way to serve a lunch portion and use the rest of each 1 L carton. |
Common buying mistakes
-
Reading “dairy-free” as “allergen-free”
Soya is itself an allergen. A dairy-free drink may therefore conflict with a pupil’s allergy plan or the school’s arrangements for packed lunches.
Check the current carton label and ask the school about its policy before packing the drink.
-
Assuming all soya drinks have the same nutrients
The UK Office for Health Improvement and Disparities’ 2025 assessment says nutrient content varies considerably among plant-based drinks.
If added nutrients matter to the household’s choice, compare the exact cartons for calcium, iodine, vitamin D and B12 rather than relying on the words “soya drink”.
-
Applying “long-life” after opening
Long-life describes storage before opening. Opened-carton instructions differ: Joybuy’s Alpro 8 x 1 L listing specifies refrigeration and use within 5 days, while Marks & Spencer’s Plant Kitchen Soya Drink specifies 3 days.
Choose a carton size the household can use within its stated interval, and note when each carton is opened.
-
Buying a sweetened multipack without trying it
Sweetened and unsweetened varieties can differ in sugars. Sainsbury’s Sweetened Soya Drink lists 2.3 g per 100 ml, while Waitrose Essential Unsweetened lists 0.0 g per 100 ml; neither figure tells you whether the pupil likes the taste.
Compare labels on a per-100-ml basis and try a smaller quantity before committing to a family stock-up.
Brand and retailer options
These examples show why the variety matters more than the brand name alone: check the current carton for its ingredients, nutrition and storage instructions.
Alpro
Alpro has several soya-drink varieties in Tesco’s UK listing, including No Sugars and original long-life drinks.
- Waitrose & Partners describes Alpro Soya No Sugars as UHT and made with added calcium, iodine and vitamins B2, B12 and D2.
- Those details describe No Sugars, not every Alpro variety; check the carton you intend to buy.
Tesco
Tesco’s soya-drink listing includes own-label sweetened and unsweetened long-life 1 L cartons.
- Both sweetness options appear in the Tesco Groceries range.
- Compare the nutrition and allergen panels of the particular variety rather than treating the two cartons as interchangeable.
Sainsbury’s
Sainsbury’s Sweetened Soya Drink is a 1 L option for households considering a sweetened variety.
- Sainsbury’s lists added calcium, iodine, vitamin D and B12 for this product.
- It lists 2.3 g sugars per 100 ml and contains soya; check that this variety suits the pupil and the school’s arrangements.
M&S
M&S lists Plant Kitchen soya drinks in sweetened and unsweetened varieties.
- Marks & Spencer describes its Plant Kitchen Soya Drink as enriched with calcium, iodine and vitamins D and B12.
- Its Plant Kitchen Soya Drink says to consume the carton within 3 days of opening; follow the instructions on the variety purchased.
Waitrose
Waitrose Essential Unsweetened Soya Drink is a long-life option for comparing unsweetened cartons.
- Waitrose & Partners lists 0.0 g sugars per 100 ml and added calcium, iodine and vitamins D, B2 and B12 for this product.
- Check its current allergen and opened-carton instructions before using it for school lunches.
Joybuy family-pack option
This 8 x 1 L long-life soya-drink pack is a household stock-up option. For a school lunch, check the pupil’s soya-allergy status, the school’s arrangements and how a serving will be packed.

Alpro Soya No Sugars Long Life Drink, 8 x 1 L
The eight 1 L cartons provide a household stock-up rather than individual lunch portions. The drink contains soya; Joybuy’s product information says to refrigerate an opened carton at +1°C to +7°C and use it within 5 days. Check the current label, the pupil’s allergy plan and the school’s arrangements before packing a serving.
Questions about school lunches
Can I put soya drink in a secondary-school packed lunch?
Check the pupil’s allergy plan and ask the school about its packed-lunch arrangements first. Department for Education guidance for England says schools must publish an allergy-safety policy and consider food brought from home, including packed lunches.
Does dairy-free mean a soya drink is suitable for pupils with allergies?
No. Soya is an allergen in its own right, as the Food Standards Agency’s allergen guidance makes clear. Read the current product label and check it against the pupil’s allergy plan and the school’s arrangements.
Do all soya drinks contain the same added nutrients?
No. The UK Office for Health Improvement and Disparities’ 2025 assessment notes considerable variation in plant-based drinks’ nutrient content. If fortification matters to your choice, compare the exact products’ labels for nutrients such as calcium, iodine, vitamin D and B12.
How long can an opened long-life carton be kept?
Follow the particular carton’s refrigeration and use instructions; “long-life” does not describe storage after opening. Joybuy’s Alpro 8 x 1 L listing specifies +1°C to +7°C and use within 5 days, while Marks & Spencer’s Plant Kitchen Soya Drink specifies consumption within 3 days of opening.
Is an 8 x 1 L pack a practical lunchbox choice?
It is a household stock-up of 1 L cartons, not a pack of individual lunch portions. Before buying, check whether the school permits the drink and how you will pack a serving while following the opened carton’s refrigeration instructions.
