Viewers avoiding a food allergen
Check the current pack’s ingredients and any “may contain” statement against the allergens you need to avoid. A vegan or gluten-free label does not answer every allergen question.
Who needs to check what?
The right bar for an evening in front of the TV depends on your specific dietary restriction and what you want from the snack.
Vegan viewers comparing protein bars
Compare the protein amount per bar as well as the ingredients. Plant-based bars can still contain soya, peanuts or other ingredients that matter to you.
Lower-sugar bar shoppers
If sugar alcohols affect what you choose, read the ingredients and any polyol warning as well as the sugar figure. This is particularly worth checking before buying several bars for evening snacks.
What matters when choosing a bar?
Settle the ingredient and allergen question first. Then compare protein, serving size and sugar information for the exact flavour you plan to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Allergen compatibility | Read the current ingredients list, highlighted allergens and any “may contain” statement. The Food Standards Agency says the 14 regulated allergens used as ingredients in UK prepacked food must be emphasised in the ingredients list. | I need to check both ingredients and precautionary wording for the allergens I avoid, even if the front of the pack carries a free-from claim. |
| Dietary claims | Check each claim separately: vegan, dairy-free and gluten-free do not mean the same thing. PhD lists its vegan, dairy-free Smart Plant Salted Caramel bar with soya and peanut paste; Tesco lists peanuts and hazelnuts in vegan, gluten-free Nakd Cocoa Hazelnut. | A plant-based bar may fit my diet, but I still need to check whether its other ingredients fit my restrictions. |
| Protein and serving | Compare protein per whole bar alongside bar weight. PhD lists 21g protein per 64g Smart Plant Salted Caramel bar; Tesco highlights 7g plant protein for its 45g Nakd Cocoa Hazelnut bar. | For a snack alongside a TV dinner, I want to know what one bar provides rather than assuming every protein bar offers the same amount. |
| Sugar and polyols | Read sugar information, ingredient names and any polyol warning for the exact bar. NHS guidance says a product with more than 10% added polyols must warn that excessive consumption may produce laxative effects. | If I am choosing a lower-sugar bar, I also want to know whether it contains sugar alcohols before eating more than one. |
Common mistakes to avoid
-
Treating free-from claims as interchangeable
PhD’s vegan, dairy-free Smart Plant Salted Caramel bar contains soya and peanut paste. Tesco’s vegan, gluten-free and dairy-free Nakd Cocoa Hazelnut contains peanuts and hazelnuts.
List the ingredients you need to avoid, then check both the ingredients and precautionary statement for the exact flavour.
-
Overlooking polyols in a lower-sugar bar
Some bars use sugar alcohols, and excessive consumption can have a laxative effect. Grenade carries this warning for its Peanut Nutter bar.
Check the ingredients and any warning on your chosen wrapper before deciding whether to buy a multipack.
-
Assuming protein amounts are alike
PhD lists 21g protein per 64g Smart Plant Salted Caramel bar, while Tesco highlights 7g plant protein for its 45g Nakd Cocoa Hazelnut bar. Their free-from claims alone do not show what one bar provides.
Compare the per-bar figures and serving sizes for the products you are considering.
-
Relying on an old listing or another flavour’s label
Ingredients and allergen information can change. Tesco advises shoppers to read the product label rather than relying solely on its website information.
Check the current wrapper for the exact flavour and pack before eating it.

Frequently asked questions
Does vegan mean a protein bar is free from other allergens?
No. PhD lists its vegan, dairy-free Smart Plant Salted Caramel bar with soya protein and peanut paste, while Barebells says all its bars contain nuts or may contain traces of nuts. Check the exact product’s ingredients and precautionary statement for your own restriction.
How do I check allergens on a UK protein bar?
Read the current pack’s ingredients and any “may contain” statement before eating. The Food Standards Agency says the 14 regulated allergens used as ingredients in UK prepacked food must be emphasised in the ingredients list; precautionary wording addresses possible unintended presence.
Can a gluten-free protein bar contain milk?
Yes. Quest describes its OG Protein Bars as gluten-free but says they use dairy-based proteins, including milk protein isolate. Check the particular pack if you also need to avoid milk or animal-derived ingredients.
What should I check on a lower-sugar bar before a long TV session?
Check its ingredients for polyols or sugar alcohols and read any warning on the pack. NHS guidance says products with more than 10% added polyols must warn that excessive consumption may produce laxative effects.
Is a supermarket product page enough to check allergens?
No. Tesco advises reading the product label rather than relying solely on website information because food products can be reformulated. Check the current wrapper for the exact flavour before eating.
