Beans have both soluble and insoluble fiber. They’re much higher in insoluble fiber, though. For instance, lentils and lima beans are 90% insoluble, and only 10% soluble fiber. Kidney and white beans are 75% insoluble, and only 25% soluble fiber.[2]

Insoluble fiber doesn’t dissolve in the water. It absorbs water, making the stool softer. Insoluble fiber has a laxative effect. Moreover, insoluble fiber supports weight loss, as it induces satiety. On the other hand, soluble fiber dissolves in the water, turning to a gel. It’s also good for weight loss, as it slows down digestion.
