Soluble 0.9g 32% Insoluble 1.9g 68%

The split is approximate and comes from USDA SR Legacy analyses where available. Soluble fiber dissolves into a gel and is the type most linked to cholesterol and blood sugar effects. Insoluble fiber adds bulk and keeps things moving.

About parsnip and fiber

Parsnips are a sweeter cousin of the carrot with more fiber per cup: 2.8 grams in a half cup sliced. Roasted parsnips shrink, so a roasted cup is denser than this number.

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 parsnip?
1/2 cup sliced of parsnip, about 78 grams, contains 2.8 grams of dietary fiber. That is 3.6 grams of fiber per 100 grams and 10% of the 28 gram daily value.
Is parsnip high in fiber?
Not especially. Parsnip has 2.8 g per serving, which ranks 19 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 parsnip soluble or insoluble?
About 32% of the fiber in parsnip is soluble (0.9 g) and 68% is insoluble (1.9 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.
How many servings of parsnip 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.
