Tiger nuts are not nuts at all. They are the small dried tubers of a sedge grass called Cyperus esculentus — a root vegetable related to papyrus. They grow underground, look like small wrinkled chickpeas, and have a naturally sweet, slightly coconut-like flavour. The name comes from the tiger-stripe markings on the outer skin. Tiger nuts are one of the oldest cultivated foods in the world, historically important in ancient Egypt and still widely consumed in West Africa and Spain, where they are used to make the drink horchata de chufa. Despite the name, they contain no nut proteins and are not related to tree nuts or peanuts.

Tiger nuts contain 400 kcal per 100g. A small handful of about 30g contains approximately 120 kcal — 6% of the adult 2,000 kcal daily reference intake. This is notably lower than almonds at 174 kcal per 30g and peanuts at 170 kcal per 30g, making tiger nuts one of the lower calorie options in the nut and seed snack category despite being quite filling due to their very high fibre content. The calories come mainly from carbohydrate and fat rather than protein.

Tiger nuts contain 33g of fibre per 100g — one of the highest fibre contents of any whole food. A 30g handful provides approximately 9.9g of fibre, which is 33% of the adult daily fibre target of 30g. For children the same handful covers a far larger proportion: 50% of the target for children aged 7 to 10 and 66% for children aged 4 to 6. By comparison, almonds provide 3.75g of fibre per 30g and peanuts provide 2.5g. Tiger nuts contain predominantly resistant starch and inulin — a prebiotic fibre that feeds beneficial gut bacteria. This makes them one of the most fibre-dense and gut-supportive whole foods available.

Tiger nuts contain 20g of sugar per 100g — approximately 6g per 30g handful, or about 1.5 teaspoons. This is higher than most nuts (almonds contain 4.4g/100g, peanuts 4g/100g) but all of it is intrinsic sugar, naturally occurring within the tuber's cell structure and packaged with fibre. 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. Tiger nuts contribute 0g of free sugar regardless of portion size. The natural sweetness is what gives them their distinctive flavour and makes them unusual among savoury snacks.

Tiger nuts contain 24g of fat per 100g — approximately 7.2g per 30g handful. Saturated fat is 4.5g per 100g (about 1.35g per handful — 6% of the adult daily saturated fat guideline of 24g). The majority is oleic acid, the same monounsaturated fat found in olive oil, making the fat profile of tiger nuts notably similar to olive oil in composition. This is a lower total fat content than tree nuts like almonds at 49.9g/100g — tiger nuts are significantly lower in fat and calories, with more of their energy coming from carbohydrate.

Tiger nuts contain 4g of protein per 100g — approximately 1.2g per 30g handful. This is low compared to true nuts and legumes: almonds contain 21.2g/100g and peanuts contain 26g/100g. Tiger nuts are not a useful protein source and should not be relied upon to meet protein needs. Their nutritional value lies in their exceptional fibre content, prebiotic properties and micronutrient profile rather than protein. Those looking to combine fibre with meaningful protein would do better pairing tiger nuts with a higher-protein food.

Tiger nuts are high in potassium (720mg per 100g, 36% of NRV) and vitamin E (4mg per 100g, 33% NRV). They are also a source of magnesium and iron. A 30g handful provides 216mg of potassium — useful for blood pressure and muscle function — and 1.2mg of vitamin E. The micronutrient profile is less dense than almonds or peanuts, but the combination of potassium and vitamin E alongside the extraordinary fibre content distinguishes tiger nuts. They do not contribute meaningful amounts of calcium, zinc, folate or B vitamins.

Yes. Tiger nuts are a NOVA group 1 whole food with 0g of added sugar, 0g of salt and no additives. Their primary nutritional value is their exceptional fibre content — 33g per 100g, with nearly 10g per 30g handful — making them one of the most fibre-dense whole foods available as a snack. The fibre is predominantly prebiotic (inulin and resistant starch), which supports gut bacteria diversity. They are lower in protein than tree nuts and legumes, so they are best thought of as a fibre-first food rather than a protein source. For those trying to increase their daily fibre intake, tiger nuts are one of the most efficient whole-food options available.

Whole dried tiger nuts are hard and chewy and present a choking risk for very young children — they should not be given whole to children under 3. From age 3 to 5, tiger nuts should be given only with close supervision and can be softened by soaking in water first. From age 5 upwards they can be eaten normally. Tiger nuts are not one of the 14 major allergens and are not related to tree nuts or peanuts — they are a tuber, making them a useful snack for children with tree nut or peanut allergies. The very high fibre content (9.9g per 30g) means that large portions could cause digestive discomfort in children — small quantities are appropriate.

No. Tiger nuts are not one of the 14 major allergens regulated under UK food law. Despite the name, they contain no nut proteins and are not related to tree nuts or peanuts. They are a tuber — a root vegetable — making them suitable for people with tree nut allergy, peanut allergy or both. Tiger nuts are also naturally gluten-free and dairy-free. Cross-contamination remains possible if tiger nuts are packaged in facilities that handle tree nuts or other allergens — always check the label if severe allergy is a concern.

Yes. Tiger nuts are entirely plant-based and suitable for vegans and vegetarians. They are a naturally vegan whole food with no animal-derived ingredients. They are also gluten-free and allergen-free, making them one of the most inclusive snack foods available. Tiger nuts are particularly useful for vegans trying to increase fibre and prebiotic intake, and for those with multiple food allergies who struggle to find safe whole-food snacks.

Tiger nuts sit in a different nutritional category from almonds and peanuts. Tiger nuts are dramatically higher in fibre — 33g per 100g versus 12.5g for almonds and 8.5g for peanuts — but dramatically lower in protein at 4g versus 21.2g and 26g respectively. They are also lower in calories at 400 kcal per 100g versus around 570 kcal for both nuts. Tiger nuts contain significantly more natural sugar (20g/100g) than almonds or peanuts, though all of it is intrinsic. Tiger nuts are not an allergen; almonds and peanuts both are. The practical conclusion: tiger nuts are a fibre-first food; almonds and peanuts are protein-first foods. They serve different nutritional purposes and complement each other well.

The fibre in tiger nuts is predominantly resistant starch and inulin — both prebiotic fibres that reach the large intestine largely intact and are fermented by beneficial gut bacteria. This fermentation produces short-chain fatty acids including butyrate, which supports the gut lining and is associated with reduced inflammation. Prebiotic fibres like inulin selectively feed beneficial bacteria such as Lactobacillus and Bifidobacterium. The result is that tiger nuts function as a gut health food beyond simple bulking — they actively feed the microbiome. The high total fibre also supports bowel regularity, and the 9.9g per 30g portion is a substantial contribution to the adult daily target of 30g.

Yes, particularly when first introduced. The high inulin content in tiger nuts is fermented rapidly by gut bacteria, and for people who are not used to high prebiotic fibre intake this can cause bloating, gas and loose stools. The effect is usually temporary and reduces as the gut microbiome adjusts. Starting with a small portion — 10-15g rather than a full 30g handful — and increasing gradually over one to two weeks is the recommended approach. Those with irritable bowel syndrome or FODMAP sensitivity should approach tiger nuts with caution, as inulin is a high-FODMAP compound. Soaking dried tiger nuts in water for several hours before eating softens them and may reduce the intensity of the fermentation response.

Tiger nuts fit best into a balanced diet as a fibre and prebiotic supplement — a way to significantly boost daily fibre intake from a whole food with no added sugar, salt or processing. A 30g handful provides 9.9g of fibre, 120 kcal and 0g of free sugar. For most adults, this single handful contributes a third of the daily fibre target. Because protein content is low, tiger nuts work best alongside higher protein foods rather than as a standalone snack. They are suitable for people with tree nut or peanut allergies who want a nut-style snack, and for anyone following a vegan, gluten-free or allergen-free diet. Introduce gradually to avoid digestive discomfort.
