What is thick fiber?

Thick fiber, also known as insoluble fiber, is a type of dietary fiber found in plant-based foods. Unlike soluble fiber (which dissolves in water), thick fiber does not dissolve in water and passes through the digestive system largely intact. This means that it helps to add bulk to the stool, promote regularity, and prevent constipation. Foods that are high in thick fiber include whole grains, vegetables, and fruits with skins or seeds (such as apples and berries). Thick fiber has also been shown to have potential health benefits, such as improving gut health, reducing the risk of colon cancer, and helping to control blood sugar levels. It is recommended that adults consume around 25-30 grams of fiber per day, with at least half of that coming from thick fiber sources.
