Are centerfugal juicers as bad as you make them sound?

Juice comparison
I enjoy your site and appreciate all the info. I can't help but notice how much you like the gear juicers and not the centrifugal models.
Can you share any hard research that supports some of these claims like enzymes getting destroyed and oxidation? I just want to make sure that's not some claim the gear juice manufactures created to sell more juicers. This is a common ploy that business or even industries can use.
Sara says:Doug, thank you for asking. This is a very common question that my visitors often ask.
I used to own a centrifugal juicer. Then I tasted the juice extracted using a gear juicer and noted the difference; then I upgraded to a twin-gear juicer and it keeps getting better. I have since thrown away my centrifugal juicer, wouldn't even give it away. I currently own four different types of gear juicers.
Here's an experiment you can do yourself and you will know what I mean. Juice 2 apples using a centrifugal juicer and leave it for 1-2 minutes. You will see that not only does the apple juice quickly turn brown, it also separates. Now, drink it and you will find that it tastes metalic instead of tasting like fresh apples. Don't you think that the metalic taste is because of oxidation of the iron in the apples?
If you can get hold of a gear juicer, do the same thing. Juice two apples and let the juice sit for 1-2 minutes. You will find that the juice is
stable and does not separate like the one extracted using a gear juicer. And it tastes like fresh apple and sweeter, which is how it should be. This shows you the presence of the enzymes and nutrients that keeps the juice together and whole. The stable juice will take a much longer time before it gets naturally oxidized (spoil).
Here's the illustration of the experiment that I did. You will see what I mean.Like you, I was skeptical at first. But since I've done this experiment myself and did some researching and thinking, I would not go back to using a centrifugal juicer. Now, many readers out there who are using a centrifugal juicer will hate me for saying this, but this is my opinion. You don't have to believe me, nor do you have to upgrade your juicer. I'm just sharing what I've found about a centrifugal juicer.
I learned the concept of juice oxidation from a man I highly respect. He was the late Dr Max Gerson, the founder of Gerson Therapy that has helped more cancer patients recover than any other known methods. Gerson Therapy primarily teaches a cancer patient to detoxify using coffee enema and nourish the body with juices and fresh foods. This is what Dr Gerson said in his book,
A Cancer Therapy: Results of Fifty Cases and the Cure of Advanced Cancer (A Summary of Thirty Years of Clinical Experimentation)
, on page 217:
"Centrifugal machines, in which air has insufficient access to the grinding process, cannot be used. When the grinding wheel rotates against a resistance with insufficient access of air, positive electricity is produced and induces negative electricity on the surrounding wall. The exchange of the positive and negative electricity kills the oxidizing enzymes and renders the juice deficient. These are findings of experiences over many years in which patients who used a one-unit machine (referring to centrifugal juicers) had no success."
Dr Max Gerson was referring that those with cancer must not drink of juices extracted using a centrifugal juicer. But I would not take the chance whether I'm healthy or not.
Happy juicing!
