Picnickers watching the snack portion
If one bar will sit alongside lunch, compare calories per bar and the bar’s weight. A smaller portion can have fewer calories without being a like-for-like alternative to a larger bar.
Who is choosing a picnic bar?
People checking dietary needs and allergens
Vegan, gluten-free and dairy-free claims answer different questions from nut, milk or soya allergen statements. Check both the ingredients and any “may contain” wording on the exact pack, particularly when sharing food.
Picnickers considering a protein bar
If protein or fibre matters more to you than minimising calories, compare those amounts alongside calories for the same bar. A protein label alone does not establish that it is a low-calorie snack.
What should you check first?
Choose the portion you expect to eat, compare its nutrition figures, then check whether its ingredients suit everyone who may have it.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Read kcal per bar and its weight. Use kcal per 100 g for a like-for-like comparison of bars of different sizes. | I want to know what one bar adds to my lunch, rather than comparing a 19 g bar with a 40 g bar as though the portions were equal. |
| Sugars | Check “of which sugars” for the bar you will eat, then read the ingredients. Nature Valley UK explains that this figure includes sugars from all sources, not just added sugar. | A fruit-and-nut bar appeals to me, but I do not want “no added sugar” to stand in for the total-sugars figure. nākd. lists 17 g sugars in its 35 g Blueberry Muffin bar. |
| Protein and fibre | Compare grams per bar alongside kcal per bar. Nature Valley UK lists 10.2 g protein, 4.4 g fibre and 196 kcal for its 40 g Protein Peanut & Chocolate bar. | I may choose a bar for its stated protein or fibre, provided its calorie contribution also fits the role I want it to play in lunch. |
| Allergens and dietary claims | Read the exact pack’s ingredients, allergen declaration and “may contain” statement. Check any vegan, gluten-free or dairy-free claim on that product, not across a brand. | If the picnic is shared, I need a bar that meets the relevant dietary requirements without overlooking nuts, peanuts, milk, soya or gluten-containing cereals. |
Common buying mistakes
-
Comparing calorie totals without comparing bar sizes
Weetabix Cereals lists Alpen Light Summer Fruit at 65 kcal for 19 g. The other product examples here weigh 35–40 g per bar, so their per-bar totals describe larger portions.
Check kcal per bar for the portion you plan to eat, and kcal per 100 g when comparing the products on the same weight basis.
-
Reading “no added sugar” as “little sugar”
nākd. describes its Blueberry Muffin bar as having no added sugar, but lists 17 g total sugars per 35 g bar. Dates and raisins are among its ingredients.
Use the “of which sugars” figure and ingredient list together rather than relying on the front-of-pack phrase.
-
Assuming a protein bar is low in calories
Nature Valley UK lists 196 kcal for its 40 g Protein Peanut & Chocolate bar; Eat Natural UK lists 220 kcal for its 40 g Dark Chocolate & Peanut Protein Bar.
If protein is your priority, compare its stated amount with kcal per bar. If keeping the snack portion lower in calories matters more, compare other formats too.
-
Overlooking allergens in a shared picnic
The compared bars include products containing nuts, peanuts, milk, soya or gluten-containing cereals, and precautionary statements differ between products.
Check each current pack’s allergen declaration and “may contain” wording before packing a bar for someone else.
Brand and product-line references
These examples describe particular bars or ranges; a brand name alone does not tell you the portion, nutrition values or allergen information of every flavour.
Alpen
Weetabix Cereals lists Alpen Light Summer Fruit at 65 kcal and 3.8 g fibre per 19 g bar.
- A small individual portion if that serving size suits your picnic lunch.
- It contains gluten-containing cereals, milk and soya; Weetabix Cereals also says it is not suitable for nut-allergy sufferers. Confirm the flavour and current pack before buying.
nākd.
nākd. lists its 35 g Blueberry Muffin fruit-and-nut bar at 131 kcal and 17 g sugars.
- This specific bar is described by nākd. as vegan, gluten free, dairy free and having no added sugar.
- It contains cashews and almonds. Check the pack’s precautionary allergen wording as well as its total-sugars figure.
Nature Valley
Nature Valley UK lists 196 kcal, 10.2 g protein and 4.4 g fibre per 40 g Protein Peanut & Chocolate bar.
- The stated protein and fibre figures give you another basis for choosing this particular bar.
- It contains peanuts, soya and milk and may contain tree nuts; compare its calories with smaller bars if portion size is the priority.
Eat Natural
Eat Natural UK lists its Dark Chocolate & Peanut Protein Bar at 220 kcal, 7.8 g protein and 2.4 g fibre per 40 g bar.
- A nut-led bar with stated protein and fibre values for shoppers comparing those figures.
- Peanuts and soya are ingredients, and the product carries precautionary wording for milk and several tree nuts.
Graze
Graze includes oat-based snack formats in its range and makes brand-level statements about nutrients in its snacks.
- Check the particular Oat Boost flavour’s serving size and nutrition panel when considering an oat-based bar.
- Brand-level statements cannot establish the calories, sugars or allergens of every individual bar.
TREK
TREK protein flapjacks are another format to consider when comparing a snack’s portion and stated nutrients.
- Compare the nutrition panel of the particular flavour and serving you intend to pack.
- Nutracheck lists several 50 g TREK protein flapjacks at 224–234 kcal per serving; check the current pack rather than treating the range as a single calorie level.

Picnic snack-bar questions
Which calorie figure should I use for a snack bar?
Use kcal per bar to assess the portion you plan to eat, then check its weight. Kcal per 100 g helps you compare formulations when bar sizes differ; it does not replace the per-bar total for your lunch.
Does “no added sugar” mean a bar has little sugar?
No. nākd. calls its Blueberry Muffin bar “no added sugar” but lists 17 g total sugars per 35 g bar. As Nature Valley UK explains, “of which sugars” includes sugars from all sources, so read that figure alongside the ingredients.
Can a protein bar fit a lower-calorie picnic lunch?
It can if its per-bar calories fit the portion you have chosen, but the protein label is not a calorie measure. Nature Valley UK lists 196 kcal and 10.2 g protein for its 40 g Protein Peanut & Chocolate bar; Eat Natural UK lists 220 kcal and 7.8 g protein for its 40 g Dark Chocolate & Peanut Protein Bar.
What about food that needs chilling at a picnic?
Follow the storage instructions for the bars and keep any foods normally refrigerated in the wider lunch cool. The Food Standards Agency advises a cool box or cool bag with ice or frozen gel packs; Food Standards Scotland also advises a cool box or bag and says to eat ready-to-eat chilled foods within four hours of taking them out of the fridge.
Do vegan or gluten-free claims settle the allergen question?
No. Check the exact product’s ingredients and precautionary statements. For example, nākd.’s Blueberry Muffin bar is described as vegan and gluten free but contains cashews and almonds, while Nature Valley’s Protein Peanut & Chocolate bar contains peanuts, soya and milk.
