What physical action does soluble fiber in black-eyed peas perform in the digestive tract?

It absorbs water and forms a gel-like substance

The fiber content in black-eyed peas is multifaceted, consisting of both soluble and insoluble types, each contributing distinct benefits. Soluble fiber specifically has the characteristic property of readily absorbing water as it moves through the digestive tract. This absorption process causes the fiber to transform into a viscous, gel-like substance. This gel formation serves multiple critical functions: it contributes to the regulation of bowel movements, and importantly, it helps control the rate at which sugars and fats are absorbed into the systemic circulation. This moderation in absorption directly assists in managing cholesterol levels by trapping dietary fats before they are fully processed.
