Day hikers planning food for a longer walk
Look at the bar alongside the rest of the food you will carry. The Ramblers advises taking carbohydrate-containing snacks during longer walks, so a protein-focused bar need not be your only option.
Who needs which checks?
The useful checks change with the length of your walk, the bar format you prefer and the ingredients you need to avoid.
Vegan or gluten-free hikers
Check the exact range and pack rather than the brand alone. TREK describes its Protein Flapjacks as plant-based and its protein-bar range as gluten-free, but those descriptions do not settle every ingredient or allergen question.
Hikers avoiding particular allergens
Read the ingredients and any precautionary allergen wording on the bar you will pack. The cited Nature Valley, Kellogg’s and Eat Natural products illustrate why a protein-focused choice can still contain nuts, milk or soya.
What matters when choosing a bar?
Start with protein per stated bar, then check how the bar fits your walking food and ingredient requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the grams of protein and serving weight for the exact product. Tesco lists 10g per 40g Nature Valley Peanut & Chocolate bar; TREK states 9g per Protein Flapjack but 15g for its separate High Protein range. | I want to know what one bar provides, rather than assuming every bar bearing the same brand name has the same protein amount. |
| Walking food | Check the carbohydrate and energy information on the pack, and consider what other food you are carrying. The Ramblers’ advice for longer walks includes carbohydrate-containing snacks. | On a longer walk, I want food options beyond a single protein bar. |
| Ingredients | Read the current ingredients, emphasised allergens and any precautionary allergen wording. Do not treat a vegan or gluten-free description as a substitute for those checks. | A bar needs to fit the ingredients I can eat, even if its protein figure or dietary description appeals to me. |
| Portion and format | Check the number of bars, weight of each bar and whether the listed nutrition applies to one bar or a different serving. Compare a flapjack with a cereal bar on those stated portions. | I would like a pack and bar size that work for the walks I have planned. |
What can catch you out?
-
Assuming every protein bar in a range is equivalent
Protein amounts differ between the cited products and even between TREK’s Protein Flapjack and High Protein ranges. Alpen’s Fruit & Nut panel, for example, lists 1.7g per 28g serving, while TREK states 9g per Protein Flapjack.
Compare protein and serving weight on the exact bar, then read the rest of its nutrition panel.
-
Taking a protein bar as your only food for a long walk
Choosing a bar for its protein figure alone leaves out the other food you may need to plan and carry. The Ramblers’ walking advice includes carbohydrate-containing snacks during longer walks.
Plan the bar alongside other foods and drinks you can carry and consume on your walk.
-
Letting a dietary description stand in for an allergen check
The cited protein-focused bars include products containing peanuts, other nuts, milk or soya, as well as products with precautionary allergen wording.
Check the current physical pack against the ingredients you need to avoid, including any “may contain” statement.
-
Relying on an older product listing
A listing may describe a different pack or recipe from the item in front of you. That matters when you are comparing portions or checking ingredients.
Confirm the pack size, nutrition and allergen information on the bar you actually buy.
Relevant brand ranges
These examples describe particular bars or ranges, not every product made by each brand.
Nature Valley
Tesco lists 10g protein per 40g Peanut & Chocolate Protein Cereal Bar.

- Joybuy’s listing for the Peanut & Chocolate cereal bars says they contain milk, peanuts and soya and may contain tree nuts.
TREK
TREK describes its Protein Flapjacks as plant-based and states 9g protein per flapjack.
- A flapjack format to consider if you prefer an oat-based bar.
- TREK’s separate High Protein range has a different stated figure of 15g per bar; check which range and flavour you are buying.
Kellogg’s

- Use the exact product’s nutrition and ingredient label before comparing it with a bar that has a stated per-serving protein amount.
Alpen
Weetabix Cereals lists 1.7g protein per 28g serving of Alpen Fruit & Nut.

Questions about hiking bars
Is the bar with the most protein automatically the right one for a hike?
No. Protein per bar helps you compare products, but the Ramblers’ advice for longer walks also includes carbohydrate-containing snacks. Check the bar’s serving size, other nutrition information, ingredients and how it fits the rest of the food you will carry.
How much protein is in the cited bars?
Tesco lists 10g per 40g Nature Valley Peanut & Chocolate bar and 8g per 40g serving of Eat Natural Maple Syrup, Pecans & Peanuts. Waitrose & Partners lists 9g per Kellogg’s Almond & Salted Caramel bar, while TREK states 9g per Protein Flapjack. Check the precise product and portion before comparing them.
Does vegan or gluten-free mean a bar has no other allergens?
No. Those descriptions do not rule out ingredients such as peanuts or soya, or precautionary warnings for other allergens. Read the ingredients and allergen information on the exact pack you intend to eat.
What should I check if I buy the same bar in a different pack size?
Check how many bars the pack contains and the weight and nutrition serving for each bar. Then compare the current ingredients and allergen wording: a familiar flavour or brand name is not a substitute for reading the pack you are buying.
