Choose reduced-fat peanut butter when you want a ready-made spread, or peanut powder when you want an ingredient for porridge, smoothies or cooking and are happy to mix it. Plain nuts serve a different purpose: they offer a ready-to-eat snack, but an unsalted label does not mean reduced fat. For an online order, compare the stated fat reduction with its named comparator, check the portion you will use and make sure any delivered substitute meets your requirements.
If you want peanut flavour in porridge, smoothies, sauces or on toast, decide whether you need a finished spread or a powder you can mix into a recipe. Check the comparison behind any reduced-fat claim and the ingredients in the particular product.
Whole peanuts are convenient to eat, but their serving size matters. The British Heart Foundation notes that 30g of nuts can contain 180–225kcal, depending on the nut; a measured portion may be more useful than eating from a large pack.
If allergens, ingredients, salt or a particular formulation determine your choice, decide in advance whether you will accept a substitute. Tesco and Sainsbury’s say they may offer substitutes when ordered groceries are unavailable unless you opt out; check the label on the item that arrives.
Choose when: You want a ready-to-spread product rather than an ingredient to prepare.
Bear in mind: Tesco’s reduced-fat smooth peanut butter contains other ingredients alongside peanuts, and its fat reduction is relative to Tesco smooth peanut butter.
Choose when: You mainly want peanut flavour in recipes or are willing to mix a spread with water.
Bear in mind: Powder needs preparation and does not replace the texture or convenience of a whole-nut snack.
Choose when: A ready-to-eat nut snack matters more to you than a reduced-fat formulation.
Bear in mind: Unsalted peanuts address salt preference, not fat reduction; compare the amount you intend to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Fat reduction | Read the named comparator and compare fat and energy on the same per-100g or prepared-serving basis. Tesco Groceries states that its reduced-fat spread has 30% less fat than Tesco smooth peanut butter; Ocado lists PBfit Original’s 87% less-fat claim against regular peanut butter when prepared as directed. | If I am replacing my usual spread, I want to know what the reduction is measured against and how much of the product I will use. |
| Serving and format | Check the labelled serving size, preparation directions and energy for the amount you intend to eat. Ocado lists 70kcal per 16g serving of PBfit Pure; its KP Unsalted Peanuts listing gives 186kcal per 30g serving. Those are different products and portions, not a like-for-like comparison. | For a snack, I would rather portion whole nuts than assume an unsalted pack is lower in energy. For cooking, I need to know whether powder will work in the recipe. |
| Ingredients and salt | Read the full ingredients list and salt figure separately from the fat claim. Tesco Groceries lists glucose syrup, maltodextrin, palm oil and salt in its reduced-fat spread; Ocado lists PBfit Pure as 100% peanuts. | A shorter ingredients list or an unsalted snack may matter to me, but neither choice automatically meets a reduced-fat aim. |
| Delivered product | Set your substitution preference before checkout. On delivery, compare the actual pack’s product form, ingredients, nutrition and allergen wording with your requirements. | If an exact formulation or allergen warning matters, I need the item delivered to meet that requirement—not just the item originally shown in my basket. |
A reduction describes a comparison, not the product’s absolute nutrition. Tesco Groceries lists 551kcal and 35.1g fat per 100g for its reduced-fat smooth peanut butter.
Check the named comparator, then compare the nutrition panel for the amount you expect to consume.
Peanut products with different formulations can have similar uses: Tesco’s reduced-fat spread contains glucose syrup, maltodextrin, palm oil and salt, while Ocado lists PBfit Pure as 100% peanuts.
Read the ingredients list alongside the fat and salt figures if formulation affects your choice.
A substitute could be a different spread, nut type or salted product, so it may not meet the requirement behind the original order.
Tesco and Sainsbury’s say substitutions may be offered for unavailable groceries unless you opt out. Set your preference before ordering and inspect the delivered item’s label before using it.
Unsalted describes salt, not fat. Ocado lists 15g fat and 186kcal per 30g serving for KP Unsalted Peanuts.
Choose unsalted nuts for that salt preference; if fat reduction is the aim, compare a suitable spread or powder with the product it would replace.
These examples show why a brand name alone cannot tell you whether an online grocery item is reduced-fat, unsalted, ready to eat or suitable for your intended use.
A reference for a ready-made reduced-fat peanut butter, rather than a whole-nut snack.

A ready-to-eat peanut reference for shoppers choosing an unsalted snack rather than a reduced-fat spread.
Its nuts category provides examples of mixed, salted, unsalted and dry-roasted formats to distinguish when ordering.
A reference for roasted, salted snack peanuts, not a reduced-fat peanut product.

No. It describes a reduction against a comparator, not an absolute fat or calorie level. Tesco Groceries says its reduced-fat smooth peanut butter has 30% less fat than Tesco smooth peanut butter, while still listing 35.1g fat and 551kcal per 100g. Check the comparator and the nutrition panel for the portion you plan to use.
Choose a ready-made peanut butter if you need a spread straight from the container; consider powder if you want to mix peanut flavour into porridge, smoothies or sauces. Ocado’s PBfit Original directions say to mix the powder with water to make a spread, so account for that preparation when deciding.
Compare the amount you will actually eat with the labelled serving. The British Heart Foundation notes that 30g of nuts can contain 180–225kcal depending on the nut, and Ocado lists 186kcal per 30g serving of KP Unsalted Peanuts. Unsalted describes the salt choice, not a reduction in fat or energy.
Allow one only if an alternative could meet the requirements behind your order. Tesco and Sainsbury’s say they may offer substitutes when grocery items are unavailable unless you opt out. Check the delivered product’s form, ingredients, nutrition and allergen wording before using it.
Read the allergen declaration and any precautionary wording on the pack you receive, including when it is a substitute. Warnings differ between products: Tesco’s reduced-fat peanut butter lists possible other nuts, while Ocado’s KP Unsalted Peanuts listing includes possible cross-contact with milk, other nuts, soya and gluten.
