Who is this for?

People packing a measured desk snack

If you want nuts alongside an office lunch without eating a multi-serving bag, choose the amount you will take before packing it. Kent Community Health NHS Foundation Trust gives small nut portions among its under-100-kcal snack examples.

Shoppers comparing plain and flavoured nuts

If salt or sugars affect your choice, read the figures for the specific product. ASDA Groceries lists 6 g sugars and 0.36 g salt in a suggested 40 g serving of its Honey Roasted Peanuts; a plain or unsalted product needs its own label check.

People packing food around allergies

Check the exact pack’s ingredients, allergen declaration and any cross-contact wording for the person who will eat it. The Food Standards Agency distinguishes peanuts, which are legumes, from tree nuts such as almonds and cashews.

What should you check?

Start with the amount you will actually pack, then compare labels for products that suit that portion.

PriorityWhat to checkYour needs
Portion energy Read energy per serving and per 100 g. Measure the amount you plan to pack; a manufacturer’s serving may not be your portion. I want to know the calories in the nuts I will actually eat. Kent Community Health NHS Foundation Trust lists 12 almonds at 80 kcal and 24 pistachios (15 g) at 90 kcal as snack examples.
Pack format Check the pack weight and whether it contains more than one intended portion. Set aside your portion before taking a larger bag to work. A small container helps me pack a chosen amount instead of deciding how much to eat at my desk.
Flavourings Compare sugars, salt and ingredients as well as energy, using the same stated portion when possible. A plain and a seasoned product need not have the same figures. I may prefer a flavoured snack, but I want to see what comes with it. ASDA Groceries lists 248 kcal, 6 g sugars and 0.36 g salt per suggested 40 g serving of its Honey Roasted Peanuts.
Allergens Read the specific pack’s allergen declaration and any may-contain wording. Check for both peanuts and tree nuts where either matters to the eater. When I pack food for someone with an allergy, the word “nuts” alone does not tell me whether the product is suitable.

Common buying mistakes

  • Treating the whole bag as a low-calorie portion

    Even a plain product can provide substantially more than an under-100-kcal snack example. ASDA Groceries lists 193 kcal for a suggested serving of its Redskin Peanuts; its KP Unsalted Peanuts listing gives 186 kcal per 30 g.

    Decide how much to pack and put that amount in a separate container rather than taking a multi-serving bag to the desk.

  • Assuming flavourings do not change the label

    ASDA Groceries lists 6 g sugars and 0.36 g salt per suggested 40 g serving of its Honey Roasted Peanuts. Its KP Spicy Chilli Peanuts listing gives 0.29 g salt per 30 g serving.

    Compare energy, sugars and salt for the portion you would eat, including when a flavoured product appeals to you.

  • Using “nuts” and “peanuts” interchangeably for allergies

    The Food Standards Agency identifies peanuts as legumes and distinguishes them from tree nuts, including almonds and cashews. That distinction matters when checking a product for a particular eater.

    Read the exact pack’s allergen and cross-contact statements, and follow the eater’s existing professional allergy advice.

  • Using an online listing instead of the pack in hand

    The label on the product you receive is the one to consult for its ingredients and nutrition information, particularly when a precise portion or allergen check matters.

    Use listings to compare options, then check the physical pack before packing or eating the nuts.

Brand and retailer examples

These product-specific label examples show why the nut, flavouring and stated portion matter more than the brand name alone.

ASDA

Own-label peanut examples include plain redskin and honey-roasted products with different nutrition figures.

  • ASDA Groceries lists 579 kcal per 100 g for Redskin Peanuts.
  • Its Honey Roasted Peanuts list 248 kcal and 6 g sugars per suggested 40 g serving; compare the portion you intend to pack.

KP

The checked KP peanut options include unsalted and spicy chilli varieties.

  • ASDA Groceries lists less than 0.01 g salt per 30 g serving of KP Unsalted Peanuts.
  • That serving still provides 186 kcal. The separately listed KP Spicy Chilli Peanuts provide 0.29 g salt per 30 g serving.

M&S

M&S lists natural, roasted, mixed and chocolate-covered nut options, so the range name alone cannot describe a particular snack.

  • Its Cashew Nuts listing gives 601 kcal per 100 g.
  • Check the individual product and the amount packed rather than applying one nutrition figure across the range.

Tesco

Tesco’s Pecan Nuts offer a plain-nut example for comparing stated serving and per-100-g energy.

  • Tesco Groceries lists 177 kcal per 25 g serving.
  • The same listing gives 707 kcal per 100 g; a plain nut is not automatically a low-calorie snack at every portion size.

Joybuy chestnut options

These Joybuy options are chestnut packs for an office snack. Choose an amount to pack and check each product’s nutrition and allergen label; they do not represent the peanut, almond or pistachio examples discussed above.

Frequently asked questions

Are nuts automatically a low-calorie snack?

No: the amount eaten matters. Kent Community Health NHS Foundation Trust gives under-100-kcal examples of 12 almonds at 80 kcal and 24 pistachios (15 g) at 90 kcal. Check the particular product’s label before choosing your portion.

Should I compare calories per 100 g or per serving?

Use per 100 g to compare products on the same weight basis, then use the serving information to assess the amount you plan to pack. A stated serving is not necessarily the amount you will eat: ASDA Groceries lists 186 kcal per 30 g serving of KP Unsalted Peanuts and 193 kcal for a suggested serving of ASDA Redskin Peanuts.

Are unsalted nuts automatically lower in calories?

No. “Unsalted” describes seasoning, not the energy in a portion. ASDA Groceries lists less than 0.01 g salt but 186 kcal per 30 g serving of KP Unsalted Peanuts, so check both figures.

Does a peanut label cover tree-nut allergies too?

Not by category name alone. The Food Standards Agency distinguishes peanuts from tree nuts such as almonds and cashews. For someone with an allergy, read the exact product’s ingredients, allergen declaration and any cross-contact wording.

Which parts of a UK food label help me compare nut snacks?

Look at energy for the portion you will eat and per 100 g, then check sugars, salt and the ingredients where those affect your choice. GOV.UK guidance also describes using traffic-light labelling to compare calorie, fat, sugar and salt information; read it alongside the stated serving size.
