Hosts planning a lower-calorie snack table
Compare the calories and weight of the bar each guest will take. A claim about protein, fibre or natural ingredients does not tell you its calories per serving.
Who is choosing the bars?
Hosts serving guests with different dietary needs
Check vegan and gluten-free claims on the exact product, then keep its ingredients and allergen information accessible. One dietary claim does not establish suitability for every guest.
Guests looking for a different kind of snack
Some guests may prefer a larger oat bar or a bar selected for its stated protein content. Put those choices alongside smaller bars without presenting them as equivalent calorie servings.
What should you check?
Start with the labelled serving you intend to put out, then compare its nutrition panel and dietary information.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Read kcal and weight for one bar, not just for a multipack or per 100 g. Sainsbury's lists Eat Natural Apple at 86 kcal per 25 g bar and Red Fruits at 87 kcal per 25 g bar. | I want guests to be able to pick up one bar with a clearly stated serving value. |
| Sugars | Compare sugars alongside kcal on the same serving basis. Sainsbury's lists 13.8 g sugars in the 25 g Eat Natural Apple bar and 12 g in the 25 g Red Fruits bar. | Even when I choose a smaller-calorie bar, I want to see its sugar value before buying the multipack. |
| Dietary suitability | Check vegan or gluten-free wording on the exact variant and read its current ingredients and allergen statement. Do not transfer a claim from one product in a brand range to another. | With different guests sharing a table, I need choices they can identify from their own wrappers. |
| Bar size and purpose | Compare grams per bar with kcal per bar. Tesco lists Graze Cocoa Vanilla Oat Boost at 116 kcal per 30 g serving; its checked Trek Original Oat and Salted Caramel flapjacks are 219 kcal and 224 kcal per 50 g bar. | Someone wanting an oat or protein-focused option may choose a larger bar, while others may prefer a smaller serving. |
Common buying mistakes
-
Taking a nutrition claim as a calorie or sugar value
In its 2025 UK supermarket snack-bar audit, Action on Salt and Sugar reported an average of 175 kcal and 7 g sugars per serving. It found that 37% of the bars assessed were high in sugars under voluntary UK traffic-light thresholds, including some products carrying a high-fibre claim.
Compare the current pack's kcal, sugars and serving weight rather than relying on claims on the front.
-
Comparing calories without comparing bar size
The checked Eat Natural Soft Fruit Bars weigh 25 g each, Graze Cocoa Vanilla Oat Boost weighs 30 g, and the checked Trek flapjacks weigh 50 g. Their per-bar calorie figures describe different-sized servings.
Note both grams and kcal per bar when deciding which types to offer.
-
Assuming one dietary claim settles allergen suitability
Nature Valley identifies gluten-free products in its Protein range, but says its Crunchy Oats & Dark Chocolate bars contain oat gluten and may contain wheat, peanuts and tree nuts. Suitability depends on the exact product.
Keep original wrappers or boxes by the serving area rather than putting unlabelled bars in a bowl. Ask guests with allergies to inspect the current pack.
Relevant brand ranges
Eat Natural
Its checked Apple and Red Fruits Soft Fruit Bars are small, individually portioned options for comparing calories per bar.
- Sainsbury's lists the Apple bar at 86 kcal and the Red Fruits bar at 87 kcal per 25 g; both are labelled vegan and gluten free.
- The same listings give 13.8 g and 12 g sugars per bar respectively. Check the current pack before serving.
Graze
The checked Cocoa Vanilla Oat Boost offers an oat-based serving for guests who want that style of bar.
- Tesco lists this vegan product at 116 kcal per 30 g serving and labels it high in fibre.
- Its oat and soya ingredients make the exact ingredients and allergen statement important checks for a shared table.
Nakd
The checked Berry Delight fruit-and-nut bar and Peanut Butter Protein Bar meet different selection needs.
- Tesco lists Berry Delight at 133 kcal per 35 g bar and the Peanut Butter Protein Bar at 7.6 g protein per 45 g bar.
- Berry Delight contains cashew and lists 17 g sugars per bar. The checked peanut bar provides 189 kcal and needs its own allergen check.
Trek
The checked protein flapjacks are larger servings than the 25 g Soft Fruit Bars.

- The product listings include precautionary allergen statements; check the particular pack before offering either bar.
Nature Valley
Its Protein range and Crunchy Oats & Dark Chocolate bars should be assessed as distinct products.
- Nature Valley lists Protein products with 7 g to 10 g protein, depending on the product, and identifies gluten-free options in that range.
- Its Crunchy Oats & Dark Chocolate serving is 199 kcal for two bars, contains oat gluten and may contain wheat, peanuts and tree nuts.

Questions about serving snack bars
How should I compare lower-calorie bars for a street party?
Compare kcal for one bar alongside its weight; the examples do not establish a universal low-calorie threshold. Sainsbury's lists Eat Natural Apple at 86 kcal and Red Fruits at 87 kcal per 25 g bar, while Tesco lists Graze Cocoa Vanilla Oat Boost at 116 kcal per 30 g serving.
Does a vegan, gluten-free or high-fibre claim settle suitability for every guest?
No. Check the precise product's current ingredients and allergen statement. Nature Valley identifies gluten-free options in its Protein range, but says its Crunchy Oats & Dark Chocolate bars contain oat gluten and may contain wheat, peanuts and tree nuts.
What allergen information should guests be able to inspect?
Keep the original packaging available so guests can read the ingredients and highlighted allergens on each prepacked bar. GOV.UK guidance, published on 23 January 2024, says relevant prepacked food labels must show the food name and ingredients list, with the 14 allergens required to be declared emphasised in that list.
Can protein flapjacks replace smaller bars when calories per bar matter most?
The checked Trek flapjacks have higher per-bar calorie values than the checked Eat Natural Soft Fruit Bars, but are also larger servings. Tesco lists Trek Original Oat at 219 kcal and Salted Caramel at 224 kcal per 50 g bar, compared with the 86–87 kcal per 25 g Eat Natural bars listed by Sainsbury's. Compare protein and serving size separately if those matter to your guests.
