Juicer create heat so they will "Cook" the Juice.
None of the juicers will "cook" juice. There is a juicer called a steam juicer that does "cook" your juice. We do not recommend this type of juicer. No matter which juicer you purchase, be assured, drinking fresh fruit and vegetable juice is an excellent way to include more fresh fruits and vegetables in your diet. Be it least oxidation, or "a little more", fresh juice is still good stuff. Fresh Juice is better than any store purchased juice, soda, coffee, etc.
