Travellers packing a savoury snack
If you want to know how much protein your airport snack provides, compare the amount for the pack or portion you plan to eat. Check salt and energy on that same basis.
Who should compare these snacks?
Active travellers between meals
A defined portion makes it easier to compare formats. Marks & Spencer lists 10g protein in its 30g nut-and-seed mix; the Eat Natural peanut-and-soya cereal bar listed by Sainsbury's provides 10.4g per 40g bar, but has different ingredients.
Travellers checking allergens
Mixed snacks can contain several allergenic ingredients. The Food Standards Agency distinguishes peanuts from tree nuts; read the current pack's ingredients and precautionary statements, particularly when buying for someone else.
What should you check before packing nuts?
Start with the portion you will carry, then compare its label and how easily you can pack it.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare grams per pack or intended serving. Note whether a figure refers to 30g, a different serving or 100g. | I want to know what the portion I actually eat provides, not just what a larger pack contains. |
| Salt and energy | Read both values for comparable portions. Sainsbury's lists 189 kcal and less than 0.01g salt per 30g serving of Chopped Mixed Nuts; its Pistachio Nuts list 181 kcal and 0.02g salt per stated serving. | If the snack is alongside other food on my journey, I want to compare more than its protein figure. |
| Pack size | Check whether the pack is one portion or needs dividing before travel. Keep the portion accessible if your hand luggage is inspected. | A small ready-to-eat pack suits me when I do not want to portion nuts from a larger bag at the airport. |
| Ingredients and allergens | Check the current pack for peanuts, tree nuts, soya, sesame and precautionary statements as applicable. Do not assume two mixed products have the same ingredients. | When I am buying for someone with an allergy, the exact product label matters more than the general description ‘nuts’. |
| Hand-luggage handling | Keep food easy to reach for a possible bag check. GOV.UK says food in hand luggage can obstruct X-ray images and may lead to a manual check; confirm the rules for your departure airport and airline. | I would rather be able to show the snack promptly if security asks to inspect my bag. |
Common airport snack mistakes
-
Comparing protein figures without checking portion sizes
A 30g nut portion and a 40g cereal bar are not the same serving. Marks & Spencer lists 10g protein per 30g pack of its nut-and-seed mix, while Sainsbury's lists 10.4g per 40g Eat Natural bar.
Compare protein, salt and energy for the amount you expect to eat, keeping each product's serving size visible.
-
Assuming mixed snacks have interchangeable allergens
The Marks & Spencer mix includes almonds and soya; Sainsbury's Chopped Mixed Nuts contain peanuts, almonds and walnuts. The Food Standards Agency identifies peanuts and tree nuts as distinct allergen categories.
Read the ingredients and precautionary wording on the current physical pack before buying or offering it to another traveller.
-
Leaving the snack decision until the airport
GOV.UK says food in hand luggage may prompt a manual bag check. A product listed by a retailer also need not be available in a particular airport shop.
If you plan to pack food, keep it accessible for screening. If you plan to buy it at the airport, check the shop's current selection rather than relying on a general product listing.
-
Treating a nut-based cereal bar as plain nuts
The Eat Natural bar listed by Sainsbury's contains peanuts and soya protein crispies alongside glucose syrup, dark chocolate, dried apricots and honey. Its ingredient mix differs from plain pistachios or mixed nuts.
Choose between these formats by reading the full ingredients and nutrition label, as well as the protein figure.
Brand and product references
These examples illustrate different pack formats; they do not indicate what an airport shop will stock.
M&S
Marks & Spencer lists a 30g Protein Packed Nut and Seed Mix with 10g protein per pack.
- The defined 30g pack makes the stated protein amount straightforward to compare with a planned snack portion.
- It contains ingredients including edamame soybeans and almonds, so it is not a plain-nut product. Its label lists 0.63g salt per 100g; check the current pack for allergens.
Sainsbury's
Sainsbury's lists a 200g Chopped Mixed Nuts pack and a 100g Pistachio Nuts pack, both of which need portioning if you want a smaller travel snack.
- Its labels state 7.6g protein per 30g serving of Chopped Mixed Nuts and 7.4g per stated serving of Pistachio Nuts.
- The mixed nuts contain peanuts, almonds and walnuts; check each product's current allergy information rather than treating the packs as substitutes.
Eat Natural
Sainsbury's lists an Eat Natural peanut-and-soya cereal bar as a sweeter alternative to a portion of nuts.
- The listed 40g bar provides 10.4g protein, making its portion size clear for comparison.
- It also contains glucose syrup, dark chocolate, dried apricots and honey. Check its current ingredients, allergens and availability before choosing it.

Questions about nuts for airport journeys
Can I take a bag of nuts through UK airport security?
Food in hand luggage may lead to a manual bag check: GOV.UK says food items can obstruct X-ray images. Keep your snack easy to reach and check your departure airport's rules and airline baggage allowance before travelling.
Should I compare protein per 100g or per pack?
For a travel snack, start with the pack or portion you intend to eat. Marks & Spencer lists 10g protein per 30g pack of its nut-and-seed mix, while Sainsbury's lists 7.6g per 30g serving of Chopped Mixed Nuts; a per-100g figure alone does not tell you what your portion provides.
Are peanuts and tree nuts the same allergen?
No. The Food Standards Agency distinguishes peanuts, which are legumes, from tree nuts such as almonds and pistachios. Check the exact pack's ingredients and precautionary statements rather than assuming a different nut product is suitable for someone with an allergy.
How does a nut-and-seed mix differ from a nut-based cereal bar?
Compare their full ingredients and portion sizes, not protein alone. The Marks & Spencer 30g nut-and-seed mix lists 10g protein; the 40g Eat Natural bar listed by Sainsbury's provides 10.4g and also contains glucose syrup, dark chocolate, dried apricots and honey.
