Nuts and gut health
Healthy dietary patterns, including those that incorporate nuts, benefit gut health. And a healthy gut, in turn, plays a crucial…
Looking to add more fibre to your day? You’re not alone! Most Australians fall short of their daily fibre needs. A handful of nuts is a healthy way to boost your fibre intake. But how much fibre do nuts contain and which ones contain the most?
Dietary fibre is important for digestive health. A fibre-rich diet supports bowel regularity, and can help prevent gut issues, such as diverticulosis and haemorrhoids.
Studies also show that fibre helps keep us feeling fuller for longer, can improve cholesterol and blood sugar levels and can assist in preventing certain diseases, such as diabetes, heart disease and bowel cancer (1-4).
A fibre-rich diet supports a healthy gut microbiota. This is because fibre feeds our gut microbes – the beneficial community of microorganisms in our digestive tract.
Fibre is only found in plant foods. It’s the indigestible parts of plant foods, such as vegetables, fruits, grains, legumes, nuts and seeds. Eating a variety of plant-based foods every day is important.
An adequate daily fibre intake is 25g for women and 30g for men (5).
Did you know? Foods with at least 4g fibre per serve are considered a good source of fibre (6). To compare the fibre content of different foods, check the 100g column on the Nutrition Information Panel of a food product.
While there’s no such thing as an unhealthy nut, they do vary in their nutritional make-up – including their fibre content. Chestnuts (14.9g/100g), almonds (10.9g/100g) and hazelnuts (10.5g/100g) contain the most fibre.
Mixed tree nuts contain 7.1g fibre per 100g (or 2.1g in a 30g handful).
Where possible, look for nuts with their skin on, as these will be higher in fibre.
Nut | Fibre (g) per 30g | Fibre (g) per 100g |
Chestnut | 4.5 | 14.9 |
Almond | 3.3 | 10.9 |
Hazelnut | 3.1 | 10.4 |
Pistachio | 2.7 | 9.0 |
Brazil nut | 2.6 | 8.5 |
Pecan | 2.5 | 8.4 |
Macadamia | 1.9 | 6.4 |
Walnut | 1.9 | 6.4 |
Cashew | 1.8 | 5.9 |
Pine nut | 1.5 | 5.1 |

Did you know? According to the latest National Nutrition and Physical Activity Survey, just 28% of Australian adults met the recommendation for fibre intake (7).
