Various beans, fruits, seeds, and grains serve as excellent sources of high soluble fiber. These foods are instrumental in promoting digestive health, as they help you feel satiated while also facilitating regular bowel movements. Dietary fiber refers to the carbohydrate component found in plants that is indigestible by the human body. Despite its significance for gut and overall well-being, many individuals fail to meet the recommended daily intake (RDI) of 25 grams for women and 38 grams for men. Both soluble and insoluble fibers contribute to stool bulk and can act as nourishment for beneficial bacteria residing in your large intestine. Soluble fiber has the unique ability to attract water into the digestive tract, which aids in softening stools and supporting regularity. This type of fiber not only promotes a feeling of fullness but also helps alleviate constipation and may assist in lowering cholesterol and blood sugar levels.

Below is a list of 20 nutritious foods that are particularly rich in soluble fiber.
