Hosts comparing fat content
If you want individually portioned bars, compare total fat per 100g first. Then check the amount in the bar or wrapped portion you intend to put out.
Who is this choice for?
For a shared game-night snack, the useful comparison depends on whether fat content, dietary suitability or portioning matters most to your guests.
Hosts checking guests’ dietary needs
Read the ingredients and allergen statements on each exact flavour and pack before serving. The products discussed here have differing ingredient and precautionary allergen statements.
Buyers prioritising other product features
Wholegrain oats, plant protein, vegan suitability or gluten-free labelling may matter more to some guests than fat content. Check those features alongside, rather than instead of, the nutrition panel.
What should you check?
Start with the same per-100g measure across bars, then check portions and the packaging guests will need to consult.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare the total-fat line per 100g. NHS food-label guidance describes 3g or less per 100g as low fat; a bar above that figure should not be called low fat just because another bar contains more. | I want to compare bars on the same basis, rather than judge their fat content by an oat, protein or wholegrain description. |
| Portion size | Check the weight and fat figure for the bar or wrapped portion. Tesco Groceries lists Kellogg’s Nutri-Grain Strawberry at 3.1g fat per 37g bar, while ASDA Groceries lists Nature Valley Oats & Honey at 7.6g per 42g twin portion. | If I put out one wrapped portion per guest, I need to know whether that wrapper holds one bar or a pair. |
| Allergens | Read the exact pack’s ingredients and any ‘may contain’ statement. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence. | Guests need access to the label before choosing a bar; a different flavour’s wrapper is not a substitute. |
| Dietary suitability | Check vegan or gluten-free declarations on the exact product, then read its fat value separately. Waitrose & Partners lists TREK Original Oat as vegan and gluten-free at 19g fat per 100g; ASDA Groceries lists TREK Smooth Lemon as vegan and gluten-free at 21g per 100g. | When a guest asks for a vegan or gluten-free option, I still want to check whether it fits the separate preference for less fat. |
Common buying mistakes
-
Assuming an oat or protein bar is lower in fat
Product descriptions can tell you about ingredients or dietary suitability without answering the fat question. ASDA Groceries lists Nature Valley Oats & Honey at 18.1g fat per 100g; the TREK flapjacks listed by Waitrose & Partners and ASDA Groceries contain 19g and 21g per 100g respectively.
Use total fat per 100g to compare candidates, then consider the other features you want.
-
Comparing only the figure per bar
A single 37g Nutri-Grain bar and a 42g Nature Valley twin portion are different amounts of food. Their per-portion figures alone do not give a like-for-like product comparison.
Compare per-100g figures first, then use the relevant per-bar or per-portion figure when deciding how much to serve.
-
Removing wrappers before guests check them
The products’ ingredient and ‘may contain’ statements differ. As the Food Standards Agency explains, a precautionary statement signals possible unintended allergen presence.
Ask about guests’ dietary requirements in advance and keep the exact packaging available when the bars are served.
Relevant brand references
These examples show why a brand or product style alone cannot settle the lower-fat choice; the figures apply to the named products, not every bar a brand makes.
Kellogg’s
The soft-baked Nutri-Grain Strawberry bar is one named option to compare when fat content is the main criterion.
- Tesco Groceries lists 8.3g fat per 100g and 3.1g per 37g bar for Nutri-Grain Strawberry.
- That per-100g figure exceeds the NHS low-fat guidance of 3g or less. The listed ingredients include wheat, oats, milk and soya.
Nature Valley
Crunchy Oats & Honey comes in twin-wrapped portions, a format to consider when planning a group snack table.
- ASDA Groceries lists a 42g twin portion and identifies oats in the product.
- ASDA Groceries lists 18.1g fat per 100g and ‘may contain’ statements for peanuts, wheat, soya and nuts.
TREK
The named Original Oat and Smooth Lemon flapjacks are options to examine when vegan and gluten-free labelling matters.
- Waitrose & Partners lists Original Oat as vegan and gluten-free, with 9g plant protein per flapjack; ASDA Groceries also lists Smooth Lemon as vegan and gluten-free.
- The respective listings give 19g and 21g fat per 100g. Check each flavour’s ingredients and precautionary allergen statement separately.

Frequently asked questions
What does low fat mean on a cereal-bar nutrition label?
For this per-100g comparison, NHS food-label guidance identifies 3g of total fat or less per 100g as low fat. A small bar can have fewer grams of fat per serving while its per-100g figure remains above that level.
Are the named bars in the fat comparison low fat?
No. Tesco Groceries lists Kellogg’s Nutri-Grain Strawberry at 8.3g fat per 100g; ASDA Groceries lists Nature Valley Oats & Honey at 18.1g and TREK Smooth Lemon at 21g; Waitrose & Partners lists TREK Original Oat at 19g. Each exceeds the NHS low-fat guidance of 3g or less per 100g. Those figures describe the named products, not every bar from those brands.
Should I remove the wrappers before putting bars out?
Keep the exact packaging available so guests can read the ingredients and allergen statements before choosing. The named products have different declared ingredients and ‘may contain’ warnings; a wrapper from another flavour may not provide the right information.
Does vegan or gluten-free labelling mean a bar is lower in fat?
No. Check total fat separately. Waitrose & Partners lists vegan, gluten-free TREK Original Oat at 19g fat per 100g, while ASDA Groceries lists vegan, gluten-free TREK Smooth Lemon at 21g per 100g.
