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 corn and fiber

A medium ear of corn provides 2.4 grams of fiber, almost all insoluble. Corn kernels have a tough outer hull that passes through largely intact, which is why it is a visible fiber source.

Frequently asked questions

How much fiber is in corn?

1 medium ear of corn, about 90 grams, contains 2.4 grams of dietary fiber. That is 2.7 grams of fiber per 100 grams and 9% of the 28 gram daily value.

Is corn high in fiber?

Not especially. Corn has 2.4 g per serving, which ranks 25 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 corn soluble or insoluble?

About 13% of the fiber in corn is soluble (0.3 g) and 87% is insoluble (2.1 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.

How many servings of corn would reach a daily fiber goal?

It would take about 11 servings to reach 25 g (the adequate intake for adult women) and 16 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.
