About peeled potato and fiber

A peeled boiled potato keeps about 1.8 grams of fiber, half of what the same potato has with its skin. Cooling cooked potatoes also forms resistant starch, which behaves like fiber in the gut but is not counted in this number.

Frequently asked questions

How much fiber is in peeled potato?

1 medium of peeled potato, about 138 grams, contains 1.8 grams of dietary fiber. That is 1.3 grams of fiber per 100 grams and 6% of the 28 gram daily value.

Is peeled potato high in fiber?

Not especially. Peeled Potato has 1.8 g per serving, which ranks 38 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 peeled potato soluble or insoluble?

About 39% of the fiber in peeled potato is soluble (0.7 g) and 61% is insoluble (1.1 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.

How many servings of peeled potato would reach a daily fiber goal?

It would take about 14 servings to reach 25 g (the adequate intake for adult women) and 22 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.
