Travellers with a long gap between meals
An individually wrapped bar is a compact snack to pack for the journey. If it is in your hand luggage, allow for a possible manual check: GOV.UK says food can obstruct X-ray images.
Who is this for?
Travellers looking for 20g or more per bar
Check the whole-bar serving rather than the range name. Named bars from Grenade, Myprotein and Barebells state 20g, 21g or 23g of protein, depending on the product; check the exact flavour you buy.
Travellers checking allergens or sweeteners
Read the exact pack’s ingredients, allergen statement and any polyol warning. These details differ between the named bars, so a protein figure alone cannot establish dietary suitability.
What should you check?
Start with the amount in one bar, then compare the rest of the label and how you plan to carry it.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the grams of protein for one complete bar and its serving weight. Check the exact flavour rather than relying on the range name. | I want a stated amount from one portable serving, particularly if I am looking for 20g or more. |
| Other nutrition | Compare energy, sugars and fibre on the same serving basis. If pack sizes differ, check the per 100g figures as well. | The protein figure matters to me, but I also want to see what else is in the bar before choosing a snack. |
| Ingredients | Read the exact flavour’s declared allergens, precautionary statements and any sweetener or polyol warning. | I need to know whether this particular bar fits my ingredient requirements before I pack it. |
| Hand luggage | Keep the pack accessible for inspection and check the requirements for your route. GOV.UK says food in hand luggage can obstruct X-ray images and may need a manual check. | I want a snack within reach, while allowing time for a possible bag check. |
Mistakes to avoid
-
Reading “high protein” as a grams-per-bar figure
The British Nutrition Foundation explains that the “high in protein” claim concerns the proportion of food energy provided by protein. It does not tell you how many grams are in one bar.
Compare the exact flavour’s nutrition panel, including the serving size and protein grams per bar.
-
Skipping the ingredient warnings
Protein bars in the named ranges can have different declared allergens and precautionary statements. Some also carry warnings about excessive consumption of polyols.
Check the pack you intend to buy, particularly if you are taking several bars on the journey.
-
Assuming a cabin-bag snack cannot delay screening
GOV.UK says food in hand luggage can obstruct X-ray images, so a bag may need to be checked manually.
Keep the bar accessible and allow for inspection. Check your airport, airline and destination requirements for the journey.
-
Counting on an airport shop for a particular bar
A retailer’s online range does not tell you what a particular airport shop will have when you travel.
If the precise protein amount or ingredient list matters, choose and check a bar before setting off.

Common questions
Can I take a packaged protein bar through UK airport security?
Check the rules for your journey rather than assuming every screening will be the same. GOV.UK says food in hand luggage can obstruct X-ray images and may require a manual bag check; check your airport, airline and destination requirements too.
Does “high protein” mean more grams per bar?
No. The British Nutrition Foundation explains that “high in protein” refers to protein providing at least 20% of a food’s energy, not to a fixed number of grams in a bar. Read the whole-bar nutrition panel to compare servings.
Can I use a protein bar instead of an airport meal?
A bar can be a snack, but its protein figure does not tell you whether it offers the variety of a meal. The NHS Eatwell Guide describes dietary balance across a day or week rather than requiring every eating occasion to be the same.
What if I need to check allergens or sweeteners?
Read the ingredients and allergen statements on the exact flavour you are buying, including any “may contain” wording. Also check for a polyol warning, particularly if you plan to take more than one bar.
Should I rely on an airport shop stocking a specific bar?
If a particular protein amount or ingredient list matters, choose and check a bar before travelling. An online grocery or specialist-retailer listing does not establish stock at a particular airport shop.
