What’s the main type of fiber of mushrooms?

Mushrooms contain both soluble and insoluble fiber. But, they consist mostly of insoluble fiber. Actually, they’re about 90% insoluble and only 10% soluble fiber.[4]

Insoluble fiber doesn’t dissolve in water. It absorbs water, making the stool softer, helping defecation. On the other hand, soluble fiber dissolves in water, turning to a gel. It slows down digestion and has satiating effects. Hence, it supports weight loss.

Furthermore, mushrooms are rich in beta-glucan. Beta-glucan is a type of soluble fiber with many health benefits. Other common foods rich in beta-glucan are oats, barley, and seaweed.

Beta-glucan seems to improve mineral absorption, like calcium and magnesium. Also, it’s an important prebiotic, as it improves gut health. It modulates the growth of beneficial probiotic bacteria in the colon.[5]

Beans (e.x. chickpeas, lentils) have the highest fiber content. A serving can provide up to 50% of the recommended daily intake!

Vegetables help meet our daily needs of fiber as well. Common vegetables, like lettucespinachcabbagekalebroccoli, and potatoes are good sources of fiber.
