BBQ cooks comparing fat content
If you want an unsweetened soya drink for a sauce, marinade or side dish, the nutrition panel gives you a clearer comparison than a front-of-pack description. Keep the units consistent when comparing cartons.
Who is this for?
Vegan cooks using soya drink regularly
A soya drink can be an ingredient in savoury recipes, but its nutrient content depends on the product. Check the carton’s fortification as well as its suitability for your recipe.
Hosts serving guests with allergies
Before adding soya drink to a shared sauce or side dish, check the exact carton and the other ingredients for allergens relevant to your guests.
What should you check?
Compare nutrition values on the same stated basis, then check how you plan to use and store the drink. The cited M&S values are per 100g, whereas the cited ASDA and Tesco values are per 100ml.
| Priority | What to check | Your needs |
|---|---|---|
| Fat and sugars | Compare total fat, saturates and sugars using matching units. ASDA Groceries lists 1.1g fat per 100ml for its unsweetened drink; Tesco Groceries lists 1.5g per 100ml for its unsweetened drink. | I want to choose by the declared nutrition values without assuming that every unsweetened drink has the same composition. |
| Heating | Read the carton’s cooking instructions. Waitrose & Partners advises heating its Essential Unsweetened Soya Drink gently and removing it from the heat before it boils because soya alternatives can separate. | For a warm BBQ sauce, I need an ingredient I can prepare according to its heating guidance, rather than assuming it will work as a direct-grill baste. |
| Fortification | Check the individual carton for calcium, vitamin D, B12 and iodine if those nutrients matter to your choice. A July 2025 UK government assessment says the nutrient content of plant-based drinks varies considerably. | If I also use soya drink regularly in place of dairy, I want to know what this particular product contains. |
| Allergens | Read the ingredients and any relevant precautionary allergen statements on the exact pack. GOV.UK identifies soya beans as an allergen that food businesses must declare when present. | When I serve a shared BBQ dish, guests need to know that the sauce or marinade contains soya. |
| Opened-carton storage | Check refrigeration and use-period instructions before choosing a pack size. Marks & Spencer says to refrigerate its Unsweetened Soya Drink after opening and consume it within three days. | If the recipe uses only part of a carton, I need a plan for the remainder before another BBQ meal. |
Common buying mistakes
-
Using a low-fat label as a cooking instruction
Fat content is a nutrition value, not a measure of how a soya drink behaves in a hot sauce. Waitrose & Partners warns that soya alternatives can curdle or separate during cooking.
Use the drink as a sauce or marinade ingredient according to its preparation guidance. Do not assume it will replace an oil-based glaze brushed over direct heat.
-
Comparing different label units as though they match
The cited M&S nutrition values are per 100g; the cited ASDA and Tesco values are per 100ml. Those figures should not be treated as an equal-basis fat ranking.
Check the units and serving basis on each current carton before comparing fat, sugars or protein.
-
Assuming a vegan label covers guests’ allergies
A vegan description does not remove soya from a recipe or tell you whether a particular guest can eat it. GOV.UK identifies soya beans as a declarable allergen when present.
Keep the carton available so you can check and communicate its ingredients and any relevant precautionary statements before serving.
-
Planning storage only while the carton is unopened
Instructions after opening can affect whether the remainder will be usable for another meal. Marks & Spencer specifies refrigeration and consumption within three days for its Unsweetened Soya Drink.
Check the instructions on the product you buy and choose a pack quantity you can store and use accordingly.

Frequently asked questions
Can I brush low-fat soya drink directly onto food on the grill?
Do not assume it will behave like an oil-based BBQ glaze. Use it as an ingredient in a suitable sauce or marinade and follow the product’s cooking guidance; Waitrose & Partners warns that soya alternatives can separate during cooking and advises gentle heating for its Essential drink.
Which cited unsweetened drinks have the lower fat figures?
ASDA Groceries lists 1.1g fat per 100ml for ASDA Plant Based Soya Unsweetened, compared with Tesco Groceries’ 1.5g per 100ml for Tesco Soya Drink Unsweetened. Marks & Spencer lists 1.4g per 100g for its drink, so check the label basis before making a wider comparison.
Does an unsweetened soya drink always have the same fortification?
No. A July 2025 UK government assessment says the nutrient content of plant-based drinks varies considerably. Check the individual carton for calcium, vitamin D, B12 or iodine if those nutrients matter to your choice.
What should I tell guests about a soya-based BBQ sauce?
Tell them that it contains soya and check the exact carton and remaining recipe ingredients for relevant allergen information. GOV.UK identifies soya beans as an allergen that food businesses must declare when present.
Can I keep an opened carton for another BBQ meal?
Follow that carton’s refrigeration and use-period instructions rather than relying on its unopened shelf life. For example, Marks & Spencer says its Unsweetened Soya Drink should be refrigerated after opening and consumed within three days.
