The correct answer is
You need both and, luckily, many high-fiber foods contain both. Insoluble fiber, which does not dissolve in water, is found in cereals, whole grain products, and some vegetables. It helps push food through the digestive track and is touted for a healthy digestive system. Soluble fiber, which forms a gel when mixed with water, is found in oats, peas, beans, certain fruits, and psyllium (a grain), and can lower blood cholesterol levels.
Switching from a low-fiber to a high-fiber diet is easily done within a few days and will provide immediate benefit.

Whoa there! Add high-fiber foods to your diet gradually. To add them overnight can cause bloating, gas, discomfort, or more serious problems. And if you are adding lots of bran and other fibers, drink plenty of fluids. Otherwise, the bran can absorb most of the water in your intestines and cause an obstruction.
