Are Mushrooms a Low-Fiber Food?

Raw Mushrooms

A cup of raw cremini mushrooms only provides about 0.5 grams of fiber, raw white mushrooms have 0.7 grams per cup and raw portobello mushrooms provide 1.1 grams per cup. However, raw chanterelle, morel and maitake mushrooms contain more fiber, with around 2 grams per cup.

Cooked Mushrooms

Because mushrooms lose water and shrink in size as they are cooked, a cup of cooked mushrooms will contain more fiber than a cup of raw mushrooms. Each cup of sliced and grilled portobello mushrooms contains 2.7 grams of fiber, a cup of cooked shiitake mushrooms provides 3 grams and a cup of cooked white mushrooms gives you 3.4 grams of fiber.

Adding Mushrooms to Your Diet

Enoki, oyster and shiitake mushrooms are among the most popular types in the United States, according to Texas A&M Agrilife Extension. Portobello mushrooms and their smaller version, called cremini mushrooms, make good substitutes for some or all of the meat in meat dishes, while oyster mushrooms have a milder flavor that goes well in stir-fries and soups. Use white button mushrooms in salads, on pizzas or in soups. Mix green beans, mushrooms, carrots and onions for a nutritious side, or toss chicken, onion, garlic, mushrooms, mushroom soup, milk and parsley into your slow cooker in the morning for a dinner that's ready to eat when you get home from work.

High-Fiber Vegetables

If you really want to increase your fiber, eat lima beans, black-eyed peas, artichokes or cooked hubbard squash, all of which provide more than 10 grams per cup. Other types of beans, peas and winter squash also provide high amounts of fiber, as do sweet potatoes, cooked greens, parsnip, baked potatoes with their skin, Brussels sprouts and broccoli.
