Monkey nuts are peanuts still in their shells. The term is the common British name for whole, unshelled peanuts — the same food as peanuts, just served and sold in the natural pod rather than pre-shelled. The shell is not eaten; it is cracked open to release the peanut kernels inside. Because you're buying the whole pod, a bag of monkey nuts contains roughly 60% edible nut kernel by weight — so a 50g bag of monkey nuts in shell yields approximately 30g of edible peanuts. Nutritionally, monkey nuts are identical to shelled peanuts once the shell is removed.

Monkey nuts (peanuts, shelled weight) contain 567 kcal per 100g of edible kernel. A small handful of shelled peanuts — approximately 30g of kernel — contains about 170 kcal, or 9% of the adult 2,000 kcal daily reference intake. If you are weighing monkey nuts in the shell before cracking, you need roughly 50g of unshelled nuts to yield 30g of edible kernel. The shell itself contains no usable calories. A single monkey nut pod typically contains 2-3 peanut kernels, each at around 6-7 kcal.

Monkey nuts (shelled peanut kernels) contain 25.8g of protein per 100g. A 30g shelled handful provides approximately 7.7g of protein — about 15% of the adult daily reference intake of 50g. This is among the highest protein contents of any whole-food snack, roughly equivalent to a large egg. Peanut protein is well-balanced relative to most plant proteins and is a useful contribution for plant-based diets. The shell contains no protein.

Monkey nuts contain 4g of sugar per 100g of shelled kernel — approximately 1.2g per 30g handful. All of this sugar is intrinsic (naturally occurring) with 0g of added or free sugar. Intrinsic sugars do not count toward the NHS daily free sugar limits of 30g for adults, 24g for children aged 7 to 10, and 19g for children aged 4 to 6. Plain monkey nuts contribute 0g to the daily free sugar total regardless of portion size.

Monkey nuts contain 49g of fat per 100g of edible kernel — about 14.7g per 30g shelled handful. Saturated fat is 6.9g per 100g (approximately 2.07g per 30g handful — 9% of the adult daily saturated fat guideline of 24g). The majority is monounsaturated and polyunsaturated fat. The shell contains no fat. Monkey nuts sold in their shells have no added oil — they are always plain, which means they retain the naturally favourable unsaturated fat profile of raw peanuts.

Monkey nuts (shelled peanut kernels) are exceptionally rich in folate — 240ug per 100g, 120% of the NRV — making them one of the best whole-food sources of this B vitamin. They are also high in copper (114% NRV), manganese (96%), vitamin E (69%) and magnesium (45%). A 30g shelled handful provides 72ug of folate — 36% of the adult daily requirement and 72% of the requirement for children aged 4 to 6. The folate content makes monkey nuts particularly relevant for women planning pregnancy, as adequate folate before and during early pregnancy is important for fetal neural tube development.

Yes. Monkey nuts and peanuts are the same food — monkey nuts is simply the British term for peanuts sold in their natural shells. The nutritional content of the edible kernel is identical. The only practical difference is presentation: monkey nuts come in the pod and must be cracked open before eating, whereas peanuts are typically sold pre-shelled. Monkey nuts sold in the UK are usually plain and unsalted — the shell makes it impossible to add salt or flavouring to the kernel itself — which makes them slightly simpler from a nutritional standpoint than many pre-shelled peanut products.

Yes. Monkey nuts are a NOVA group 1 whole food — the least processed food category — with 0g of added sugar, 0g of salt and no additives. They provide protein, healthy unsaturated fats, fibre and an excellent range of vitamins and minerals, particularly folate and vitamin E. Because they are always sold in the shell and thus always plain and unsalted, monkey nuts are nutritionally cleaner than many pre-shelled peanut products. The act of cracking the shell also naturally slows eating pace, which can help with portion awareness. A 30g shelled handful is the standard healthy portion.

Whole peanut kernels from monkey nuts are a choking hazard for children under 5 and must not be given to this age group — whether shelled by an adult or not. The shell itself is also a choking and injury hazard for young children. From age 5 upwards, shelled peanuts from monkey nuts can be introduced carefully with supervision. For children under 5, peanut butter (smooth), ground peanuts or peanut powder are the recommended safer alternatives and can be introduced from around 6 months as part of weaning. Peanuts are one of the 14 major allergens — introduce to infants gradually and watch for any reaction. Consult a GP if there is a family history of peanut allergy or the child has eczema.

Yes. Monkey nuts are peanuts and peanuts are one of the 14 major allergens regulated under UK food law. Peanut allergy can cause reactions ranging from mild hives and itching to severe anaphylaxis, which can be life-threatening. The shell does not reduce the allergen risk — the peanut proteins are present in the kernel inside. Peanut allergy is separate from tree nut allergy (peanuts are legumes, not tree nuts) though cross-reactivity occurs in some people. Anyone with a known or suspected peanut allergy must avoid monkey nuts entirely. Cross-contamination risk exists even with the shells intact if stored or handled alongside other allergens.

Yes. Monkey nuts are suitable for vegans and vegetarians. They contain no animal-derived ingredients — just peanuts in their natural shell. As always sold plain and unsalted, they are one of the most straightforward vegan whole-food snacks available. For vegans, the folate, magnesium and vitamin E content make monkey nuts a particularly useful food. They are naturally gluten-free, though those with coeliac disease should check for cross-contamination on packaged products.

The shell of a monkey nut is not eaten and contains no usable calories. All nutrition figures for monkey nuts apply to the shelled edible kernel only. As a rough guide, the shell accounts for about 35-40% of the total weight, meaning 100g of monkey nuts in shell yields approximately 60-65g of edible kernel. So if you are counting calories by weighing the bag before shelling, divide the in-shell weight by 1.6 to get the approximate edible kernel weight, then apply 567 kcal per 100g. A 50g portion of monkey nuts in their shells therefore yields approximately 30g of kernel and about 170 kcal.

Cracking monkey nut shells one at a time introduces a natural pause between each mouthful. Research on shelled versus unshelled peanuts has found that people tend to eat fewer calories when they have to remove the shell themselves — the manual effort creates a physical and psychological barrier that slows the eating rate. This is not unique to peanuts; the same principle applies to edamame in pods, pistachios in the shell and other foods that require some preparation before eating. For those who find it easy to overeat pre-shelled nuts, switching to monkey nuts is a practical way to maintain the same nutritional benefits while naturally moderating intake.

Monkey nuts (peanut kernels) stand out for their protein content at 25.8g per 100g — the highest of any common nut or legume snack, ahead of almonds at 21.2g and walnuts at 15.2g. They are also the best whole-food source of folate among nuts at 240ug per 100g. Where they fall behind: almonds have more than twice the fibre (12.5g versus 8.5g) and are significantly higher in calcium and vitamin E. Walnuts are a better source of omega-3 ALA. For protein and folate, monkey nuts are the strongest choice among nuts. For fibre and calcium, almonds lead.

Monkey nuts fit well into a balanced diet as a whole-food snack that is always plain and unsalted. A 30g shelled portion provides 170 kcal, 7.7g protein, 2.55g fibre and 72ug folate without adding any free sugar or salt. The NHS Eatwell Guide recommends unsalted nuts as a healthy snack and counts them as part of daily healthy fat intake. The shell-cracking process also makes overeating less likely than with pre-shelled nuts. For adults and children aged 5 and over without peanut allergy, monkey nuts are one of the most nutritionally efficient and naturally portion-controlled snack foods available.
