Picnickers choosing a bar between meals
Compare the nutrition for the whole bar you plan to eat. Protein is one figure to consider alongside sugars, saturated fat and energy, especially when bars come in different sizes.
Who needs to check what?
People looking for a vegan option
TREK labels its Cocoa Oat flapjack vegan and states that it contains 9g plant protein per 50g bar. It contains soya and carries precautionary statements for peanuts, nuts and milk, so check the wrapper against each guest’s needs.
Households sharing food with guests who have allergies
The documented Nature Valley, Kellogg’s, TREK and Eat Natural examples contain or may contain peanuts, other nuts, soya or milk. Choose from the exact pack’s ingredient and allergen information, and keep its wrapper available at the picnic.
What matters when choosing a bar?
Start with the portion you will eat, then check whether the ingredients and storage directions work for everyone and everything you are packing.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the protein amount for one bar and note its weight. Use per-100g figures when comparing bars of different sizes; a protein claim alone does not describe the rest of the nutrition panel. | I want to know how much protein the portion I will actually pack provides, not just what the front of the wrapper calls it. |
| Other nutrition | Compare sugars, saturates, salt and energy per bar. Check the per-100g column too when portion sizes differ; the NHS identifies these as information to look for on food labels. | If I am choosing between several snacks, I want to see the other nutrition figures alongside protein. |
| Ingredients and allergens | Read the exact pack’s ingredient list, allergen declaration and precautionary statements. Check vegan or gluten-free wording for that product rather than assuming it applies across a brand. | Everyone sharing the picnic needs an option that fits their own ingredient and allergy requirements. |
| Picnic storage | Follow each bar’s storage instructions and keep its wrapper intact. The Food Standards Agency advises keeping foods normally refrigerated at home cool on a picnic; Food Standards Scotland recommends a cool box or bag with ice or frozen packs. | I need to pack wrapped bars and chilled picnic foods according to their different storage directions. |
Picnic buying mistakes to avoid

Assuming a protein claim tells the whole nutrition story
Bars with protein claims can still differ in sugars, saturates, salt and energy. Different bar weights can also make per-bar figures harder to compare at a glance.
Read the full nutrition panel: use per-bar values for the portion you will eat and per-100g values to compare products of different sizes.
-
Choosing for a group without checking allergens
The documented nut-based and oat-bar examples contain or may contain allergens including peanuts, other nuts, soya and milk. A vegan or gluten-free label does not settle a separate allergy question.
Ask what each guest needs to avoid, check the current wrapper and retain the packaging so its declaration remains available.
-
Packing wrapped bars and chilled food as though they need the same storage
Food Standards Agency picnic guidance says foods normally kept in the fridge at home need to stay cool at the picnic. A bar’s own storage directions determine how to pack that product.
Keep chilled items in a cool bag or box with ice or frozen packs, and follow the bar wrapper’s directions for storing the bars.

Common questions
Does a cereal bar need to go in the picnic cool bag?
Follow the bar’s pack instructions rather than putting it in the cool bag automatically. The Food Standards Agency’s picnic advice is to keep foods normally refrigerated at home cool; store wrapped bars according to their own directions and use a cool bag for the chilled food.
Which of these documented bars is vegan?
TREK labels its Cocoa Oat flapjack vegan and lists 9g plant protein per 50g bar. It contains soya and may contain peanuts, nuts and milk, so check the current wrapper separately for allergy suitability.
Which documented options are labelled gluten free?
Nature Valley Protein Peanut & Chocolate and Eat Natural Dark Chocolate & Peanut are labelled gluten free on their named product pages. Check the exact current pack before buying, particularly when choosing for someone who must avoid gluten, and assess other allergens separately.
How can I compare bars of different sizes?
Use protein and other nutrition figures per bar to assess the portion you will eat, then use per-100g figures to compare products with different bar weights. Read sugars, saturates, salt and energy alongside protein; the NHS identifies these among the figures provided on food labels.
