Does blending fruit destroy the fiber?


Blending fruit or vegetables for a smoothie does not destroy the fiber in them.

While blending does increase the oxidation of the produce items, it is not going to cause a great loss of nutrients. Oxidation occurs when fruits and vegetables are cut and exposed to oxygen. The loss of nutrients by oxidation is not going to be much, regardless of how long a smoothie is blended, because oxidation takes time. Read more on that here.

If you are juicing fruits and vegetables, this will remove the fiber because those fibrous materials are being separated from the liquid in the produce items when pressed. It is recommended that only about half of your fruit intake come from juice or in the form of a beverage so that you maximize fiber (since most juices have removed the fiber).
