FAQs – Juicing & Juicers
There are four juices used on the Gerson Therapy: green juice, carrot juice, carrot/apple juice, and orange (or grapefruit) juices.
No, every ingredient is there for a specific purpose, and adding unapproved ingredients into the juices can negatively impact the overall function of the therapy.
Don’t substitute. Find as many ingredients as possible and make the juice without the missing ingredients. Incorporate the missing ingredients once they become available again.
Any juice is best when consumed immediately after juicing, as the healing enzymes die off as the juice oxidizes. Green juice may not be stored, it must be consumed right away. Carrot-apple juice is best consumed right away, but may be stored if necessary up to 72 hours.
It is best to store the juice in small 8 oz. mason jars, filled up to the top so there is no room for oxygen, and refrigerated, or, if traveling, placed in a cooler. A small container is better than a thermos or a larger jar, as each time a larger container is opened, more air gets in and further oxidizes the juice. A smaller container is best because it is not opened multiple times.
The Gerson Therapy is modified for type II diabetes patients in the early stages to avoid certain foods. For more information about the diabetes protocol, please read and/or download the PDF below:
If you are following the Gerson Therapy, the protocol should be followed precisely, without modifications (unless advised by a qualified Gerson doctor). But if you are healthy, it is your own personal decision to add other juices. You can use the Food Reference Guide (PDF), also available in the Gerson Therapy books, for the Gerson dietary guidelines.
No, it will dilute the nutrients in the juices. There is already distilled, organic water in the juices that has been extracted from the fruit and vegetables. Some herbal teas such as peppermint tea and chamomile tea are fine to drink, but should always be made with distilled water.
Under no circumstances are non-organic ingredients to be substituted for organic ingredients. Patients who have done this have quickly found it to be detrimental to their recovery. This is especially true of root vegetables like carrots, which absorb toxins in the soil.
For example, the herbicide Roundup is one of the most toxic substances you can put in your body. Concentrating a chemical like Roundup with a press type juicer and drinking it is extremely harmful.
Make the juices without the missing organic ingredients until they become available again.
Raw spinach is not permitted on the Gerson Therapy. It has oxalic acid in its raw form which inhibits the absorption of some necessary nutrients. Cooked spinach is fine to eat though, as heat destroys the oxalic acid.
Do not substitute red or yellow apples (for example, red or golden delicious apples). The preferred substitute would be another type of tart apple (for example, Fuji). Return to the Granny Smith variety once they become available. Read more about what to do when granny smiths are out of season here:
The Gerson Therapy for cancer requires a two-step machine, with a grinder and a hydraulic press. This type of juicer has two separate components, a grinder to grind the vegetable into a fine, moist, pulp and a hydraulic press to extract the juice of the vegetable from the pulp by squeezing it under high pressure. Research in this area, although limited, indicates that juice produced by the grinder/press can be as much 50 times higher in certain essential nutrients, and will produce 25 to 50% more than other juicers from the same amount of raw produce.
We strongly recommend using the Norwalk juicer, which is the most effective grind and press machine on the market, and the one we have had the most success with. The price of the Norwalk juicer is approximately $2,400 new, and used Norwalks (though hard to find) cost less. The next-best alternative is to buy the Champion juicer, but only use it as a grinder, and buy a separate hydraulic press. This option usually costs around $600 for both machines—less if you find a used Champion.
For healthy people (or non-cancer patients) following the Gerson diet, it is not strictly necessary to buy a heavy-duty juicer like the Norwalk. There are several other options which would be acceptable. For more information about which types of juicers are best for the Gerson Therapy, read the Gerson Guide to Juicers.
