Also, is there a difference in health benefit and what is a source of soluble fiber. I had never heard of soluble fiber before until someone mentioned they heard soluble fiber helped decrease cholesterol levels. Found mostly in oat bran, melons, and dried fruits.
Soluble fibre helps reduce cholesterol levels by eliminating bile.
Cholesterol is used to make bile and upon digestion of food bile is released. Bile binds to soluble fibre, but since the fibre can't be broken down, it and the bound bile are excreted in the feces. Insoluble fibre is the 'roughage' that helps keep things moving. Fiber Cellulose or fiber, the structural part of plants, is not properly a nutrient, since it is neither digested nor absorbed. It is now thought that the fiber found in whole-grain cereals, including the hulls called bran, is of greater importance to the intestine than that in fruits and vegetables.
