If low fat is a firm requirement for elevenses, check the fat figure per 100g: UK nutrition-claims legislation sets a limit of 3g per 100g for a solid food described as low fat, and M&S lists 1.5g per 100g for its Whole Chestnuts. If you prefer ordinary mixed nuts, measure a portion rather than treating them as low fat; Sainsbury's lists 17.5g fat per 30g serving for its Mixed Nuts. A pack described as “reduced fat” needs its own comparison with a similar product—it does not, by itself, tell you that the food is low fat.
Check the fat figure per 100g rather than relying on a small pack size. M&S Whole Chestnuts list 1.5g fat per 100g, within the 3g-per-100g limit in UK nutrition-claims legislation for a solid food described as low fat.
A measured serving of plain mixed nuts offers a different snack from chestnuts, but portion control does not make it low fat. Sainsbury's lists 17.5g fat, 6.3g protein and 2.6g fibre per 30g serving of its Mixed Nuts.
Compare plain and flavoured recipes if added salt or coatings matter to you. For an allergy, read the ingredients and any cross-contact warning on the current pack; a product name alone cannot establish suitability.
Choose when: low fat is a firm requirement and the product's per-100g figure meets the applicable threshold.
Bear in mind: chestnuts differ in texture from conventional mixed nuts; M&S lists 31.0g carbohydrate per 100g for its Whole Chestnuts.
Choose when: you want conventional nuts and are happy to serve a measured portion rather than buy a low-fat food.
Bear in mind: Sainsbury's Mixed Nuts contain 58.2g fat per 100g and include several types of tree nut.
Start with the per-100g label to assess a low-fat claim, then use the serving information to judge the amount you plan to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Fat claim | Check fat per 100g: UK nutrition-claims legislation permits “low fat” on a solid food at no more than 3g per 100g. For “reduced fat”, check what similar food the claim compares with; do not assume it meets the low-fat limit. | I want to tell a low-fat product from a smaller pack of ordinary nuts. In a Food Standards Agency and Ipsos survey of 611 adults interviewed in Northern Ireland between September and November 2024, 49% said they actively used traffic-light labelling when shopping for food; that figure is not specific to nuts or fat claims. |
| Portion | Compare energy and fat both per 100g and per serving. Sainsbury's lists 195kcal and 17.5g fat per 30g serving of its Mixed Nuts. | For an ordinary nut snack, I'd rather put a serving in a small container than eat from a sharing bag. The British Heart Foundation uses 30g as a small-handful reference. |
| Flavouring | Read the ingredients and compare the fat, saturates, sugars and salt figures on plain and flavoured packs; a portion pack or coating is not a reduced-fat claim. | Plain or unsalted nuts suit me when I want to avoid added salt or choose without a sweet or savoury coating. |
| Allergens and age | Read the current ingredients and cross-contact warnings for nuts, peanuts, sesame and other relevant allergens. Sainsbury's Mixed Nuts also carry a choking warning for small children. | Before sharing the snack, I need to check that the exact product and its form are suitable for the person who will eat it. |
Pack size changes how much you might eat, not the product's fat content per 100g. Placement among reduced-fat snacks does not establish a claim for an individual nut product either.
Read the per-100g panel first. Under UK nutrition-claims legislation, a solid food described as low fat must contain no more than 3g fat per 100g; check the comparison behind any separate “reduced fat” claim.
Fat type and total fat are different questions. Sainsbury's Mixed Nuts list 58.2g total fat per 100g, regardless of whether you serve a smaller amount.
Choose a chestnut product with a qualifying label figure if low fat is essential. Otherwise, treat plain mixed nuts as a portion-controlled alternative, not an equivalent low-fat product.
Coatings and seasoning can change a nut snack's sugar, saturates and salt figures. The British Heart Foundation advises comparing flavoured choices with plain nuts rather than assuming the coating makes no difference.
Check the current per-100g and per-serving figures when comparing salted, honey-roasted, dry-roasted and plain varieties.
A mixed-nut title does not list every ingredient or cross-contact warning. Sainsbury's also warns that small children can choke on its Mixed Nuts.
Read the current pack for allergens and warnings before serving it, particularly when buying for someone with an allergy or a small child.
M&S Whole Chestnuts provide a specific example for checking a strict low-fat requirement.
Sainsbury's Mixed Nuts are a reference for a measured serving of conventional nuts, not a low-fat product.
KP describes Honey Roast Peanut Snack Packs in 5 × 30g multipacks, alongside salted and dry-roasted options in its snack-pack range.
Tesco's baked and reduced-fat snacks category covers several types of snack, rather than serving as a nutrition claim for every item within it.
These listings are for the chestnut route. Compare the current pack's fat figure per 100g, ingredients and serving size before deciding whether one meets your elevenses needs.

A chestnut option to assess against a strict low-fat requirement. The listing identifies 180g and three packs; check the current pack's fat figure per 100g and allergen information.

This 180g chestnut listing offers a different pack configuration from the three-pack option above. Check its per-100g nutrition and current pack warnings before choosing it for elevenses.

The named 50g pack may suit someone choosing a smaller chestnut pack for elevenses. “Light Pack” is part of the product name, not proof of a low-fat claim; check the nutrition panel per 100g.

For someone planning several chestnut snacks, this listing names a 400g pack. Decide on the portion you would serve and check the current per-100g nutrition and ingredients.
No image available
The name describes ready-to-eat, peeled chestnuts in a 1kg pack of 10 sachets. A sachet is not automatically the portion you want for elevenses; check the pack's serving information and fat per 100g.
No. Under UK nutrition-claims legislation, a solid food described as low fat must contain no more than 3g fat per 100g. A reduced-fat claim compares a food with a similar product, so read that comparison and the per-100g nutrition panel rather than assuming the low-fat limit is met.
Do not assume they are. Sainsbury's Mixed Nuts list 58.2g fat per 100g; serving less changes the amount eaten, not the product's per-100g figure. If low fat is essential, check a different product's label against the applicable limit.
The British Heart Foundation uses a small handful of about 30g as a portion reference and says its energy content varies by nut type. Check the serving information on the pack you buy, then measure the amount you intend to eat rather than relying on the size of a sharing bag.
Flavouring alone says nothing about a reduced-fat claim. Compare the current fat, saturates, sugars and salt figures for salted, honey-roasted or dry-roasted nuts with a plain option, and check any comparison stated on a reduced-fat pack.
Read the current ingredients and any cross-contact warning for the exact pack. GOV.UK guidance says nuts and peanuts are among the allergens that must be clearly identified in the ingredients list of prepacked food when present; a mixed-nut product may also carry warnings relevant to other allergens.
