Hosts comparing fat across bar sizes
If you want a lower-fat choice for a Halloween snack table, compare the per-100g figures before looking at individual portions. A smaller bar can have less fat per wrapper without having less fat per 100g.
Who is choosing?
Hosts serving guests with dietary requirements
Vegan or gluten-free labelling can help narrow a choice, but it does not answer an allergen question for every guest. Check the ingredients and precautionary statements on each current wrapper.
Hosts planning individual portions
For a self-serve table, the amount in one wrapped serving matters as well as the per-100g figure. The compared products list servings ranging from a 30g Graze bar to a 42g Nature Valley two-bar serving.
What should you compare?
Start with the nutrition panel on a consistent per-100g basis. Then consider the wrapped portion and screen each product against your guests’ dietary and allergen needs.
| Priority | What to check | Your needs |
|---|---|---|
| Fat per 100g | Read the fat figure per 100g on each current pack. Use that common measure when bar weights differ; a lower figure by itself does not establish a ‘reduced fat’ claim. | I want to compare bars of different sizes without mistaking a smaller portion for a lower fat concentration. |
| Fat per serving | Check the stated serving weight and fat in that serving. Nature Valley UK lists 7.7g fat in its 42g two-bar serving; Tesco Groceries lists 6.5g in a 30g Graze Cocoa Vanilla Oat Boost. | Each guest may take one wrapped serving, so I also want to know what that serving contains. |
| Allergens | Read the ingredients and precautionary allergen statements on every current wrapper. Keep the product information with the bars on a self-serve table. | I need guests to be able to identify what is in each bar before taking one, rather than treating a mixed selection as suitable for everyone. |
| Dietary labelling | Check vegan, gluten-free and other declarations for the exact product, then read its fat figures separately. Tesco Groceries lists nākd. Peanut Delight as vegan and gluten-free, with 23g fat per 100g. | A guest may need a particular dietary option, but I do not want to mistake that label for a statement about fat content or allergens. |
Mistakes to avoid
-
Calling a bar ‘reduced fat’ because its figure is lower
A comparison between the fat figures on two packs does not, by itself, establish that either product qualifies for a ‘reduced fat’ claim.
Describe the specific comparison instead, such as which of the bars you are considering has less fat per 100g.
-
Comparing only the number on each wrapper
Tesco Groceries lists 6.5g fat in a 30g Graze Cocoa Vanilla Oat Boost, while Nature Valley UK lists 7.7g in a 42g two-bar serving. Their per-100g figures go the other way: 22g for Graze and 18.4g for Nature Valley.
Use per 100g for the like-for-like nutrition comparison, then use the serving figures to plan what you will offer.
-
Assuming fruit, nuts or no added sugar means less fat
Tesco Groceries lists 23g fat per 100g for nākd. Peanut Delight and 30.1g per 100g for Eat Natural Hazelnut & Date. Those figures answer a different question from the bars’ ingredients or dietary declarations.
Read the fat line as well as the product description, and choose according to the attributes that matter for your guests.
-
Separating bars from their allergen information
The compared bars have different ingredients and precautionary statements, including references to peanuts or other nuts. A shared bowl without identifiable wrappers makes those differences harder for guests to check.
Retain the original wrappers and make each product’s information easy to identify. Check each current pack before offering it to someone with an allergy.
Brand and product references
These figures refer to the named products, not every bar made by each brand. Compare the current pack of the variant you intend to serve.
Nature Valley
Nature Valley UK lists 18.4g fat per 100g and 7.7g per 42g two-bar serving for Crunchy + Fibre Cocoa & Hazelnut. It has the lowest per-100g figure among the four named comparison products.
- The two-bar serving weight makes the per-serving figure clear.
- The manufacturer says this product may contain soy, wheat, peanuts and tree nuts; check the current wrapper for guests with allergies.
Graze
Tesco Groceries lists 6.5g fat per 30g bar and 22g per 100g for Graze Cocoa Vanilla Oat Boosts. Its smaller serving has less fat per listed portion than the other three compared products, but not the lowest per-100g figure.
- The 30g serving provides a distinct portion size to consider for a snack table.
- Check the exact product’s ingredients and allergen statement; do not apply these nutrition figures to a different Graze bar.
nākd.
Tesco Groceries lists Peanut Delight as vegan and gluten-free, with 23g fat per 100g and 8g per 35g bar. Its dietary declarations and fat figure need separate consideration.
- The named product offers vegan and gluten-free declarations for guests who need those options.
- Peanut Delight contains peanuts. Check the current wrapper for its full ingredient and precautionary allergen information.
Eat Natural
Tesco Groceries lists 30.1g fat per 100g and 12g per 40g bar for Eat Natural Hazelnut & Date with Peanuts & Almonds. It is a fruit-and-nut option, rather than the lower-fat-per-100g choice among these four products.
- The product name identifies its hazelnut, peanut and almond ingredients.
- It contains those nuts; check the current pack for the complete allergen statement before serving.
Snack bars on Joybuy
These Joybuy snack-bar options include different flavours and pack sizes for a Halloween snack table. For each exact product, check the current nutrition panel for fat per 100g and per serving, and retain its wrapper for ingredient and allergen information.

Questions about choosing bars
Does less fat than another bar mean ‘reduced fat’?
No: a lower figure in a comparison does not by itself establish a ‘reduced fat’ claim. Compare the stated fat per 100g, and distinguish your comparison from any claim made on the product’s pack.
How do I compare a 30g bar with a 42g serving?
Use fat per 100g for a consistent comparison, then check fat per stated serving for the amount you plan to offer. GOV.UK and the Food Standards Agency identify traffic-light labelling as a way to compare fat and other listed nutrients between foods.
Can I serve a mixed bowl if a guest has a nut allergy?
Do not assume the mixed selection is suitable for that guest. Nature Valley UK says its Cocoa & Hazelnut bars may contain peanuts and tree nuts; the named nākd. and Eat Natural bars contain peanuts or other named nuts. Check every current wrapper, keep products identifiable and discuss the guest’s requirements before offering a bar.
Is a vegan or gluten-free bar necessarily lower in fat?
No. Tesco Groceries lists nākd. Peanut Delight as vegan and gluten-free, while declaring 23g fat per 100g. Check dietary declarations, ingredients and the nutrition panel separately.
Which of the four compared bars has the least fat per listed serving?
Graze Cocoa Vanilla Oat Boosts has the lowest listed serving figure among those four products: Tesco Groceries states 6.5g fat per 30g bar. Nature Valley UK lists a lower fat figure per 100g for its Crunchy + Fibre Cocoa & Hazelnut bars, so the choice changes with the measure you use.
