Is power juicers eliminate all of the fiber of juice?

by Eric James on June 12, 2010

Hello all. Can anyone tell me if power juicers (such as VitaMix, Blendtec, Jack LaLanne, etc.) remove all/most of the fiber from whole fruits and veggies? Or if the juicers otherwise breakdown the fiber to the point where it no longer acts as fiber?

As I know it, it’s generally better to eat a whole apple, for example, than it is to drink apple juice. The whole apple contains fiber that offsets the apple’s sugar and prevents it from causing a huge insulin response. But apple juice doesn’t have the fiber to offset the sugar. Therefore, apple juice sends a lot of unmitigated sugar into your system, and you do get an unhealthy insulin surge.

Does it work the same way when you do your own juicing? Or is there a way to keep the fiber content–maybe by keeping the pulp made by the juicer?

Thanks in advance for any advice.

The main problem is that the protective factor of eating a whole fruit (versus juicing) is that the fiber encapsulates the sugars. When you juice or blend or chop up fine, you separate the sugars from the fiber. It doesn’t do much good to drink the juice & fibers together, you still have the huge influx of sugars that overwhelm the body.

Juice has soluble fiber and, depending on what fruit or vegetable that has been juiced, insoluble fiber. Soluble fiber aids the digestive process and promotes overall health by lowering cholesterol and limiting sugar absorption. Insoluble fiber acts as a natural laxative. So yes juice has soluble fiber.

Yes, I think that separation of juice and the fiber will not be good either – even if you drink them together in some form or another. I don’t have any scientific data for that, but just my gut feel.

While drinking too much fruit juice is nor recommended, I love them myself occasionally. You can mix fruit with some vegetables. For example, apples go very well with celery.
