Just one handful of macadamia nuts contains 2.4g of dietary fibre, similar to a slice of wholemeal bread3.
Did you know there are different types of dietary fibre that benefit your body in different ways4 and macadamia nuts have a combination of these essential fibre types?
The role of fibre in our gut health
Dietary fibre is important for digestive and metabolic health5. Insoluble fibre is what we most often think of as beneficial for regular bowel function. It’s the undigested roughage that is not fermented and bulks up stools. Soluble fibre helps with cholesterol reduction and regulating blood sugar levels, as well as bulking up stools by absorbing water to aid regular bowel function. And the fibre in nuts, like macadamias, can help to reduce feelings of hunger, which is important in managing weight6.
Fermentable fibre for good health
Nuts like macadamias also contain prebiotic fibre7. This is fibre that is a fermentable food for your gut’s natural bacteria and fungi (called microflora). When this prebiotic fibre is fermented by gut bacteria, short chain fatty acids are produced that are beneficial to the gut microbiota. This activity plays a role in the production of the ‘happy hormone’ serotonin8 as well as influencing hormones that affect weight management, appetite, blood sugar regulation and the immune system9. So, by eating prebiotic fibre from nuts you are stimulating a healthy colony of gut bacteria to benefit your overall health10,11,12.
Macadamias and the microbiome
There is still a lot to learn in the area of gut health. But we know that eating nuts like macadamias is a delicious way to ensure we are eating a range of dietary fibre each day, including some prebiotic fibre7,12. Read more about macadamias, gut bacteria and the microbiome.
