Is the Juice Cleansing Movement All Hype or Are There Real Health Benefits
The impetus to juice is to enjoy the health benefits associated with the consumption of additional vegetables, herbs, roots, and fruit. Juicing, if done correctly, will allow "the juicer" to get many more plant-sourced vitamins, minerals, and phytochemicals into their body than would otherwise not be possible if consumed by traditional mastication (chewing up and swallowing).
Juicing is NOT about getting an additional source of fiber into the diet. It's the exact opposite. Juicing extracts and disposes of the fiber from the produce being juiced, thereby, leaving the liquid portion devoid of time-consuming, need-to-be-digested fiber, in the juicer's catch-cup for speedier digestion upon swallowing. The liquid dispelled by the juice extraction machine contains all of the vitamins, minerals, and beneficial plant compounds of those juiced vegetables, herbs, roots, and fruits. Vitamins, minerals, and plant compounds that would otherwise be missing from a diet that's based upon lean animal-sourced protein and under 50 grams of carbohydrates (the amount of carbs found in 1 cup of long-grain brown rice or ~1 cup of baked sweet potatoes) like the Paleo, Ketogenic, and Atkins-type diets.
Juicing experts and educated juice advocates recommend juicing primarily green vegetables, a few root vegetables for their dense mineral content, and very little low-sugar fruit. Most American diets are not lacking in fruit. The Standard American Diet (SAD) is reported in clinical research as being low in green vegetables like broccoli, cabbage, kale, spinach, and Brussel sprouts. Dietary questionnaires and patient interviews show that the majority of Americans are able to eat an apple, an orange, a tomato, or a banana daily, but the average American has difficulty trying to find the time to make a pot of green beans, steam a pan of asparagus, or boil turnip greens for a nutritious side item at mealtime.
Dark green vegetables are high in protein (though many uninformed critics of juicing say otherwise), vitamins, and minerals and low in glucose unlike root vegetables and fruit which can contain as much sugar as a 1/2 can of Coke to the shock of many a store-bought juice lover (1 cup of green grapes contains 21grams of sugar minus the fiber versus 19.5grams of sugar in a 1/2 can of coke). A ketogenic dieter or a paleo adventure lover wanting to add a clean-burning plant-based protein to their diet could make a green juice that contains 1 bunch of broccoli with its 17.15grams of protein and 1 head of cauliflower with its 16.13grams of protein and wind up with a glass of vegetable juice that contains 33.28grams of total protein which is equivalent to ~4.5 ounces of cooked 93% lean ground beef without the added cholesterol and naturally derived animal hormones.
There is a science to juicing just as there is a science or method to cooking. Cooking requires some know how and so does juicing. To create a vegetable juice that is nutritious and well balanced, it is advisable to read a few good books on the subject written by dietary chefs who have been educated in juicing or by professional juice therapists. There is a plethora of misinformation on the internet and books published which have been written by overnight authors who do not know the subject matter which they are writing about. There is also an equal number of juice critics that for one reason or another want to put the kibosh on juicing by suggesting that those who juice will become protein deficient. As you can see for yourself from the above-referenced example, adequate protein can be easily had in one glass of vegetable juice if one juices protein-dense vegetables and not primarily sugary fruits that are low in protein.
Protein, vitamins, minerals, essential fatty acids, and carbohydrates can all be found in a big glass of green juice. Governmental research shows Americans just aren't getting enough vegetables in their daily diet so why not try to consume a single glass of vegetable juice each day. An easy way to do this is to make a glass of vegetable juice for breakfast. A morning glass of green juice will contain just as much protein without the added cholesterol as eating a breakfast egg, sausage, and cheese omelet with the exact same amount of fiber as the extracted vegetable juice -- ZERO. An egg and sausage or egg and bacon breakfast contains no fiber as does a glass of extracted vegetable juice. Therefore, why are pundits arguing against juicing not realizing that the standard American breakfast is oftentimes devoid of fiber as well is beyond me.
In conclusion, juicing can be incorporated into ones diet in order to get the recommended daily allowance of vitamins and minerals. Juicing can also add a clean-burning source of plant-based protein to someone's diet whose percentage of dietary protein maybe too rich in animal meat. Juicing can be low in sugar if the amount of juiced fruit is kept to a minimum -- just enough fruit to make a juice palatable for consumption. And, lastly, a great rule of thumb I tell my clients who are about to embark on a juicing program is "juice your vegetables and eat your fruit."
Thank you for your continued literary support. It is heaven to be able to write and your readership provides the clouds on which I pen my prose.
