Shoppers tracking carbohydrate
If you are choosing nuts for a keto-style plan, compare total carbohydrate per 100g and for the portion you expect to eat. A reduced-fat description cannot answer that question on its own.
Who is this for?
Shoppers comparing salt
If salt matters to you, compare the exact products rather than relying on a brand name. ASDA Groceries lists 0.03g salt per 100g for KP Unsalted Peanuts; that figure does not make them a reduced-fat product.
Households checking allergens and age suitability
Check the current pack for ingredients, allergens and may-contain statements, particularly with mixed nuts. Whole nuts also need care around small children because of choking risk.
What should you check?
Start with carbohydrate for a like-for-like product comparison, then check your portion and any separate requirements for fat, salt or ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Compare labelled total carbohydrate per 100g, then check the figure for the portion you will eat. Tesco Groceries lists 5.1g per 100g for Tesco Macadamia Nuts; ASDA Groceries lists 5.7g per 100g for KP Unsalted Peanuts; Marks & Spencer lists 9.7g per 100g for M&S Natural Nut Medley. These figures describe those products, not every nut of each type. | I want to see how a specific snack portion fits the carbohydrate allowance in my plan. |
| Fat | Read the fat figure separately from carbohydrate. Tesco Groceries lists 77.8g fat per 100g for Tesco Macadamia Nuts, ASDA Groceries lists 51g for KP Unsalted Peanuts, and Marks & Spencer lists 56.2g for M&S Natural Nut Medley. HEART UK describes ketogenic diets as high in fat. | If reducing fat is a separate requirement for me, I need to assess it directly rather than assuming a reduced-fat label helps with carbohydrate. |
| Salt and seasoning | Compare salt per 100g and read the ingredient list. ASDA Groceries lists 0.03g salt and 5.7g carbohydrate per 100g for KP Unsalted Peanuts, versus 1.6g salt and 7.3g carbohydrate for KP Dry Roasted Peanuts, which contain a flavouring mixture. | I would choose between unsalted and seasoned peanuts using the figures on those exact packs, not the words ‘dry roasted’ alone. |
| Allergens and format | Read the current pack’s ingredient and may-contain statements. Tesco Macadamia Nuts may contain peanuts, other nuts and sesame; M&S Natural Nut Medley is labelled unsuitable for people with nut, peanut or sesame allergy. | My household may need to avoid particular allergens, and whole nuts are not a suitable snack to offer to small children. |
Common buying mistakes
-
Assuming reduced fat means keto suitability
Fat and carbohydrate answer different questions. HEART UK describes a ketogenic diet as very low in carbohydrate and high in fat; a reduced-fat description does not establish the carbohydrate content of a snack.
Compare total carbohydrate per serving and per 100g first. If reducing fat is also important to you, assess that as a separate requirement.
-
Judging seasoned nuts by their name
ASDA Groceries lists different figures for two KP peanut products: the dry-roasted variety has 7.3g carbohydrate and 1.6g salt per 100g, while the unsalted variety has 5.7g carbohydrate and 0.03g salt per 100g.
Read the ingredients, carbohydrate and salt on the exact pack you are buying.
-
Forgetting the portion
A per-100g comparison does not tell you how much carbohydrate is in the amount you eat. Tesco Groceries lists 1.3g carbohydrate and 19.5g fat per 25g serving of Tesco Macadamia Nuts.
Check the labelled serving size against your intended portion and use that portion’s carbohydrate figure in your plan.
-
Skipping allergen and choking checks
Ingredients and may-contain statements differ between nut products. Whole nuts can also pose a choking risk for small children.
Read the current pack’s allergen information each time, and do not offer whole nuts to small children.
Relevant brand references
These product-specific label examples help illustrate different checks; a brand name alone does not establish the nutrition or allergen details of another product.
KP
The two KP peanut varieties listed by ASDA Groceries provide an unsalted-versus-seasoned comparison.
- KP Unsalted Peanuts list 5.7g carbohydrate and 0.03g salt per 100g.
- KP Dry Roasted Peanuts list 7.3g carbohydrate and 1.6g salt per 100g and contain a flavouring mixture. Check the allergen statement for either product.
Tesco
Tesco Groceries’ macadamia listing provides a plain-nut example for comparing labelled carbohydrate and fat.
- Tesco Macadamia Nuts list 5.1g carbohydrate per 100g and 1.3g per 25g serving.
- The same product lists 77.8g fat per 100g, so it is not a reduced-fat example. Its allergen statement says it may contain peanuts, other nuts and sesame.
M&S
Marks & Spencer’s Natural Nut Medley illustrates the checks involved when choosing several nut types in one pack.
- It contains cashews, almonds, Brazil nuts, pecans and pistachios.
- The listing gives 9.7g carbohydrate and 56.2g fat per 100g and labels the product unsuitable for people with nut, peanut or sesame allergy.
Joybuy product options
These options include nut snacks and whole chia seeds for adding to food. Compare each product’s current label with your intended portion and needs; the chia seeds are an alternative ingredient, not a nut snack.

KP Snacks Unsalted Roasted Peanuts 250g
An unsalted peanut option if you want to compare salt as well as carbohydrate. The pack is 250g; check its current nutrition and allergen label for the portion you plan to eat.

Volong Macadamia Nuts 500g Tin
A macadamia option if you prefer this nut type. Check this 500g tin’s own carbohydrate and fat figures rather than applying figures from a different macadamia product.
No image available
BE&CHEERY Pistachios 500g
A pistachio option if that is the nut you want to snack on. Use this 500g product’s current label to check carbohydrate, salt, allergens and a suitable portion for your plan.
No image available
Be&Cheery Creamy Flavour Macadamia Nuts 100g
A flavoured macadamia option rather than a plain one. For this 100g pack, check the ingredient list alongside total carbohydrate and salt before deciding whether it suits your plan.

Natural Selection Whole Chia Seeds 200g
Whole chia seeds are an ingredient to consider for adding to food, not a substitute for a ready-to-eat nut snack. Check this 200g pack’s preparation directions and nutrition label before use.
Questions about keto-style nut snacks
Are reduced-fat nuts automatically suitable for keto?
No. HEART UK describes a ketogenic diet as very low in carbohydrate and high in fat, so a reduced-fat claim does not establish whether a particular snack fits your carbohydrate allowance. Check the exact pack’s total carbohydrate, ingredients and serving size.
Which of the compared products lists the least carbohydrate?
Of the three retailer products compared here, Tesco Groceries lists the lowest total carbohydrate per 100g for Tesco Macadamia Nuts: 5.1g, or 1.3g per labelled 25g serving. ASDA Groceries lists 5.7g per 100g for KP Unsalted Peanuts, and Marks & Spencer lists 9.7g for M&S Natural Nut Medley. This is a comparison of those labels, not of every macadamia, peanut or mixed-nut product.
How do KP unsalted and dry-roasted peanuts differ?
Choose between these specific products using the nutrient figures and ingredients that matter to you. ASDA Groceries lists 0.03g salt and 5.7g carbohydrate per 100g for KP Unsalted Peanuts, compared with 1.6g salt and 7.3g carbohydrate for KP Dry Roasted Peanuts; the dry-roasted product also contains a flavouring mixture. Check the current pack when buying.
Should I check allergens on every pack of nuts?
Yes, if allergens matter in your household: read the current pack’s ingredients and may-contain statement rather than assuming products from the same brand are alike. For example, Tesco Groceries says its Macadamia Nuts may contain peanuts, other nuts and sesame, while Marks & Spencer labels its Natural Nut Medley unsuitable for people with nut, peanut or sesame allergy.
What if I have diabetes and am considering a major dietary change?
Speak with your diabetes healthcare team before making significant changes to a low-carbohydrate eating plan. Diabetes UK says this is especially important if you use insulin or diabetes medicines that increase the risk of hypos.
