Fiber: Soluble or insoluble?
You need both types of fiber in your diet. Soluble, which dissolves in water, can help lower cholesterol and glucose levels. Good sources of soluble fiber include oats, beans, apples, citrus fruits, carrots and barley. Insoluble fiber, which doesn't dissolve in water, promotes the movement of material through your digestive system and can help with constipation or irregular stools. Good sources of insoluble fiber include whole-wheat flour, wheat bran, nuts and many vegetables.

Juicing is no substitute for whole foods
Juicing fresh fruits and vegetables produces a liquid that contains most of the vitamins, minerals and phytonutrients found in the whole fruit or vegetable. However, healthy fiber is lost during most juicing. So be sure your diet also includes a variety of whole fruits and vegetables.
