Nobody should get all their fiber from one food. Gut bacteria respond to variety, and the fiber calculator shows a mixed day that reaches your number.

Frequently asked questions

How much fiber is in macadamia nuts?
1/4 cup of macadamia nuts, about 34 grams, contains 2.9 grams of dietary fiber. That is 8.5 grams of fiber per 100 grams and 10% of the 28 gram daily value.
Are macadamia nuts high in fiber?
Not especially. Macadamia Nuts have 2.9 g per serving, which ranks 8 of 21 nuts and seeds in the FiberUp database. It still counts toward plant diversity, but the fiber in a meal will come from elsewhere.
Is the fiber in macadamia nuts soluble or insoluble?
About 10% of the fiber in macadamia nuts is soluble (0.3 g) and 90% is insoluble (2.6 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.
How many servings of macadamia nuts would reach a daily fiber goal?
It would take about 9 servings to reach 25 g (the adequate intake for adult women) and 14 servings to reach 38 g (adult men). Spreading fiber across several foods is easier and better for gut bacteria diversity.

Values are per typical serving from USDA FoodData Central and standard references, rounded to one decimal. Actual fiber varies with variety, ripeness, and preparation. This is general nutrition information, not medical advice.
