Parents packing school snacks
Check the labelled portion if you want a small, individually wrapped bar. Read its sugars and ingredients as well as its calories, and check the school’s packed-lunch rules before putting it in a bag.
Who is choosing the snack?
Older pupils choosing a snack
A larger oat or protein bar may suit a different appetite from a small fruit bar. Compare the whole portion you expect to eat rather than treating every bar as the same size.
Families checking allergens
Use the current pack’s ingredient and allergen information for the exact variety. The school’s allergy arrangements matter too, particularly for bars containing nuts or carrying may-contain warnings.
What should you compare?
Start with the eating unit—a single bar, a two-bar pack or another labelled serving—before comparing the rest of the nutrition panel. A portion-based calorie screen is not a judgement about whether a snack meets a child’s individual needs.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare kcal per bar or labelled serving, then check how many bars are in the portion. Ocado lists Eat Natural Apple at 86 kcal per bar and Red Berries at 87 kcal per bar; Nature Valley UK labels its Crunchy Oats & Honey serving as two bars (42 g). | I’m packing one snack, so I want to know what the whole portion I put in the bag contains. |
| Sugars | Read sugars for the same portion used in the calorie comparison. Check the nutrition panel even when the front of the pack emphasises fruit or says no added sugar. | A smaller bar could still have a sugar amount I want to compare with other options. |
| Ingredients and allergens | Read the exact variety’s current ingredients, emphasised allergens and may-contain statements. Check the school’s allergy and packed-lunch policy separately. | The snack needs to fit the eater’s requirements and the rules at their school; a vegan or fruit-based description is not enough to decide that. |
| Protein and fibre | Compare the amounts per labelled serving alongside its size and calories. Ocado describes TREK Choc Caramel as providing 12 g of plant protein per bar; that figure does not describe every protein bar. | For a more substantial snack, I may consider a larger bar rather than choosing solely by the smallest calorie number. |
Common mistakes to avoid
-
Reading “under 100 kcal” as the whole nutritional picture
That figure describes a portion, not its sugars, ingredients or suitability for school. Bars of different sizes can also give very different impressions when compared only by the number on the front.
Find the portion size on the nutrition panel and read the other values for that same portion before making a choice.
-
Comparing one bar with a two-bar serving
Nature Valley UK labels Crunchy Oats & Honey as a two-bar serving (42 g), while Ocado’s calorie figures for Eat Natural Apple and Red Berries refer to individual bars. Those are different eating units.
Decide how much will actually go into the lunchbox, then compare the nutrition information for those portions.
-
Assuming a fruit or plant-based bar meets allergy rules
A product’s flavour or dietary description cannot replace its allergen statement. The researched Eat Natural soft fruit bars list almonds, while the referenced TREK and nākd. protein bars list peanuts.
Check the current pack for the exact variety and consult the school’s published allergy and packed-lunch rules before sending it.
-
Choosing a protein bar for a small lunchbox extra
A protein-focused bar and a small fruit bar serve different portion preferences. Choosing by the word “protein” alone can overlook the size of the snack and its allergens.
Decide what role the bar has in the packed lunch, then compare its labelled serving and ingredients with smaller options.
Brand and product-line references
These examples help distinguish bar formats; a brand name alone does not establish the nutrition or allergens of every variety.
Eat Natural
Ocado lists the Apple and Red Berries Soft Fruit Bars at 86 and 87 kcal per bar respectively.
- Individual fruit-bar portions provide a clear per-bar figure for comparison.
- These varieties list almonds; check each pack’s sugars and additional allergen warnings.
TREK
Ocado describes its Choc Caramel protein bar as providing 12 g of plant protein per bar.
- A protein-focused format to compare when a larger snack is wanted.
- The referenced variety contains peanuts and soya; check its portion size and current allergen statement.
nākd.
Ocado describes the Protein Peanut Butter bar as having no added sugar.
- That description may be relevant when comparing ingredient and sugar information.
- No added sugar does not state the bar’s calorie amount or mean it contains no sugars. This variety contains peanuts.
Nature Valley
Nature Valley UK labels its Crunchy Oats & Honey serving as two bars (42 g).
- The labelled two-bar serving makes it possible to compare the portion you intend to pack.
- Do not apply that serving information to a different Nature Valley variety; check each pack’s ingredients and allergens.
Alpen
Alpen says some of its products are no longer made, so the exact bar range matters when considering this brand.
- Check the specific product and its current pack information rather than relying on an older bar name.

Questions about school snack bars
Should I compare the front of the pack or the nutrition panel?
Use the nutrition panel to compare the portion that will actually be eaten. A pack may contain more than one bar: Nature Valley UK, for example, labels Crunchy Oats & Honey as a two-bar serving (42 g), whereas Ocado’s Eat Natural Apple figure is for one bar. Read the ingredients and allergen information too.
Can I put a nut-containing bar in a school packed lunch?
Check that school’s published allergy and packed-lunch rules before sending one. The referenced Eat Natural soft fruit bars list almonds, and the TREK and nākd. protein varieties list peanuts; their suitability cannot be decided from the product category alone.
Does no added sugar mean fewer calories?
No. “No added sugar” describes something different from the calories in a serving. Ocado uses that wording for the nākd. Protein Peanut Butter bar; compare its labelled calories, sugars and portion size with those of the other bars you are considering.
How should I keep a bar in a school bag?
Follow the storage instructions on the exact pack. The referenced Eat Natural and TREK products call for a cool, dry place; check a different variety’s label rather than assuming its instructions are identical.
