It is recommended that between 5 and 9 servings of fruits and vegetables should be eaten each day. While that may seem overwhelming, a juicer can help to reach that goal. While juicing removes the insoluble fiber, it retains the soluble fiber. Consumed on an empty stomach, nutrients in juice form are more easily absorbed. However, the best juicer is the one that you will actually use and doesn't destroy the nutrients through oxidation.
