Frequently asked questions

How much fiber is in spaghetti squash?
1 cup cooked of spaghetti squash, about 155 grams, contains 2.2 grams of dietary fiber. That is 1.4 grams of fiber per 100 grams and 8% of the 28 gram daily value.
Is spaghetti squash high in fiber?
Not especially. Spaghetti Squash has 2.2 g per serving, which ranks 29 of 60 vegetables in the FiberUp database. It still counts toward plant diversity, but the fiber in a meal will come from elsewhere.
Is the fiber in spaghetti squash soluble or insoluble?
About 27% of the fiber in spaghetti squash is soluble (0.6 g) and 73% is insoluble (1.6 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.
How many servings of spaghetti squash would reach a daily fiber goal?
It would take about 12 servings to reach 25 g (the adequate intake for adult women) and 18 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.
