juicing too much can be unhealthy

8 Reasons to Not Juice

Biological Reasons Not to Juice:

  1. Chewing is important
  2. Fiber prevents sugar from entering our bloodstream to quickly.
  3. Fiber is filling.
  4. Liquidized food fails to stimulate peristalsis (muscle contractions of digestive organs that moves food through the body).

Practical Reasons Not to Juice:

  1. Juicing is not natural.
  2. Juicing is laborious.
  3. Juicing oxidizes fruit.
  4. Eating fruit is juicy.

Disclaimer:  Some bodies, that have permanently lost the ability to digest foods properly, may need to juice in order to receive the proper nutrients to stay healthy.  In this instance, even with its downsides, juicing could be the best option for you.  However, before determining that your body is incapable of proper digestion, I highly advise successive liver and gallbladder cleanses so that you can fully diagnose your bodies digestive capabilities.


Biological Reasons Not to Juice:

1.  Chewing is very important:

In short, the mouth is an organ of the digestive system.  As a digestive organ, the mouth plays an important role in breaking down food.  It does this through chewing and chemical decomposition.  When smoothies or juices are consumed, this important part of digestion is skipped, which can compromise the rest of the digestion process.

Let me break it down for you:

Similar to every other living thing, a plant’s goal is to survive.  In order to survive, plants must defend themselves against their natural prey, which are bacteria, insects, and disease.  A plant’s first line of defense against this prey is external.  Well-known examples of these external defenses include, “prickly thorns, poison, or wax coating”.[1]

If this first line of defense is penetrated and prey enters the interior of the plant, it defends its survival with a second line of defense.  In its second line of defense, “plants produce antibodies of which 20,000 kinds are known to date, still only a fraction of what plants are capable of producing”.[2]   These antibodies are toxic to animals and humans when ingested and can make them sick.  What allows us to eat plants without experiencing sickness is our salivary enzymes.

Let me explain.  In order to protect itself against its own toxins, plants contain neutralizing compounds in its fibrous parts.  When fruits or vegetables are chewed, their fibrous parts are broken and saliva is released into the mouth.  This allows the neutralizing compounds to be released and activated.  Thus, the plant’s toxins are counteracted.  That is some jaw-knocking good news.

The problem with juicing is that the fibrous part of the plant (usually the skin) is removed.  This means that the compounds that neutralize the plants toxins are missing.  “The human body can deal with a certain number of plant toxins without a problem, but there is a limit.  Juicing or making green smoothies means that these plant toxins occur freely and unbound, and thus in higher concentrations that would otherwise be there if you ate these as solid foods.

The body’s immune system identifies natural plan toxins and tries to discard them, along with the rest of the juice, as quickly as possible.  This greatly reduces nutrient absorption.” [3]  If you chew fruits and vegetables, rather than juice them, natural plant toxins are not an issue.  This is why chewing food is very important.

What about blending?

Yes, making smoothies with whole fruits and vegetables means the fiber and neutralizing components of these plants are present.  However, unless you chew, salivary enzymes do not activate the compounds that neutralize the plant toxins.  Therefore, multitudes of unbound plant toxins are still ingested when smoothies are consumed.  If you must blend or juice, read this first to ensure you get the best nutrient absorption out of your smoothie.

Ok, back to biological reasons to not juice:


2.  Fiber prevents sugar from entering the bloodstream too quickly.

The natural sugar in fruits absorbs into our bloodstream very quickly, within a matter of minutes.  In fact, underneath your tongue there is a place where sugar can enter your bloodstream even before you swallow.  This is because our cells feed on sugar.  Or, in scientific terms, glucose.  Therefore, it is very important that sugar gets into the bloodstream.  Without it, we could not function.  It is part of who we are as humans.

But, even though cells need glucose to function, if there is too much sugar in our bloodstreams problems may occur.  You have heard of “high blood sugar” right?  So, what regulates sugar’s entrance into the bloodstream?  You guessed it, fiber.  This is one reason why it is important to consume the fiber of fruits and vegetables and not remove them through juicing.


3.  Fiber makes you full.

When you juice, it is possible to consume many more fruits or vegetables than you could through simply eating.  Say you want a full cup (or 8 oz.) of apple juice.  How many apples will it take to make this amount?  I do not know really, because each apple is different, but for the sake of this explanation I will say 4 medium apples makes 8 oz. of apple juice.  If you were to eat 4 apples, it may take 30 minutes.  Personally, I have found that 4 apples is to many for me to consume in one sitting, [without a stomach ache.]

But, to drink the sugar, vitamins, and remaining minerals left after you juice 4 apples, it could take 10 minutes.  If you were thirsty, you may even consume a cup of apple juice in 1 minute.  Thus, your body is flooded with the sugar from more apples than you could reasonably consume in this short amount of time.

What is even worse about this scenario is that now, your body must deal with the sugar of 4 apples without any fiber to slow down the sugars entrance into the bloodstream.  In addition to this, your body must deal with the natural toxins of 4 apples because it does not have the neutralizing compounds that the fiber of the apples contained.  Overall, this is a potential recipe for malnutrition, toxicity, and indigestion, which is why eating the fiber of your fruits and vegetables is important.


4.  Liquidized food fails to properly stimulate peristalsis.

What is peristalsis and why is it important?  You may ask.  Do not worry; just keep reading, I answer those questions here.  If you read this and still have questions, make sure to ask them in the comment section below.

In short, peristalsis is the name given to a series of muscle contractions and relaxations that push food through your digestive organs.  Peristalsis is important because it allows your body to digest food and absorb nutrients.

Let me explain:

After food is swallowed, peristalsis begins in the esophagus where smooth muscles contract and relax in a wave-like motion to push food into the stomach.  Have you ever swallowed something too large and waited as it painfully progressed down the esophagus?  Then, you have consciously experienced the movement of these muscles in the first stage of peristalsis.

The second stage of peristalsis occurs in the small intestine, after the stomach has digested food into a liquid mixture (chyme).  Here peristalsis takes the form of short waves of muscle contractions and relaxations.  This movement allows chyme to mix in the small intestine while gradually moving forward.  This allows the small intestine to absorb nutrients through its intestinal walls.

The last stage of peristalsis takes place in the large intestine where the muscles contract and relax periodically (1-3 times a day) to move large masses of what is now waste matter through the colon and into the rectum where your body can dispose of it.  Gut-tightening information, I know, but why did I explain all of this?

My point is the process of peristalsis is necessary for good digestion.  “When the fibrous part of the food is removed through juicing or is cut into tiny fragments during blending, the liquidized foods fail to properly stimulate peristalsis.”[4]  Peristalsis is not triggered by simply swallowing or by the presence of just any food in the gut.  It is prompted by the presence of fiber.  This is why every fruit, vegetable, and nut contains fiber.  A lack of digestive fiber can mean sluggish, slow, and incomplete food digestion and elimination.  In other words, stomach trouble.


This is why it is very important to consume the fiber of fruits and vegetables.  Have I convinced you yet?  Continue on to read 4 practical reasons not to juice.


Practical reasons not to juice:

Aside from how the body responds biologically to consuming fruit juice, there are a few other reasons not to juice.

1.  Juicing is not natural:

Apart from the citrus fruit, it is very difficult to create juice without tools.  Obtaining tools means spending money and, in this case, having electricity.  Two things that may be inconvenient for you.  Certainly, for this child of the wilderness, spending $40.00 to $400.00 dollars to get the juice out of fruits and vegetables does not seem worth it, especially when I can just use my choppers.


2.  Juicing is Laborious:

When I first started learning about the power of fruits and vegetables to supply the body with everything it needs, I bought a juicer.  Before I knew much about how the body works, I primarily used it to make supplement meals for an obese friend of mine that had asked me to help him lose weight.

Every morning, I would go to his apartment with a load of fruits and vegetables.  I would clean all of these fruits and vegetables and peal them or cut off the inedible parts.  I would fill a large bowl with my ready to juice produce and then run it through the juicer to make two cups of juice, one for each of us.  Sometimes, it would take two large bowls of fruits and vegetables to make two cups of juice.

Afterward, I removed the pulp catcher and collected all the discarded parts of the produce.  Not wanting to waste I experimented with spreading the pulp across the dehydrator screens to create fruit and vegetable jerky.  Sometimes this worked, other times, it failed, especially if the pulp contained bits of seed.

After this, I would wash the bowl; the pulp catcher; the mouth of the device that the food pushed through; the fruit pushing tool; and worst of all, the blade.  Since the blade used tiny holes to separate the chopped up fruit parts from the juice, it was impossible to clean completely.  No amount of scrubbing, soaking, or hand washing did it.  The holes were just too small.  Because of this, the juicer constantly attracted fruit flies.

So, in addition to juicing, I made many attempts to keep the kitchen clear of fruit flies.  By the way, the most affective method I found for killing fruit flies was leaving out a cup of apple cider vinegar.  Bottom line, the whole process of juicing is too labor intensive for me.  Especially when to simply eat fruits and vegetables is so simple.


3.  Juicing Oxidizes Fruit:

If you have ever seen the innards of an apple turn brown, you know oxidation.  After a fruit or vegetable is cut, or shredded by a juicer, it releases its enzymes and other nutrients.  This process is supposed to happen in your body, where vitamins and nutrients can go toward healthifying your internal system (yes, healthifying is a scientific term, it is just so new you have not heard it :)).  If, however, fruits and vegetables are broken open outside of the body, those nutrients go elsewhere within minutes.

A solution to this is juicing right before you intend to drink the juice and then drinking it quickly as soon as it is made.  However, this is only a semi-solution, as you will still encounter problems.  See “biological reasons not to juice” and “juicing is laborious”.


4.  Eating fruit is juicy

Last, but not least, I do not juice with a machine because my teeth can juice for me.  When you chew a juicy, freshly picked, organic fruit you are juicing.  You are juicing naturally, straight into your mouth and it is the healthiest way to enjoy the juice of any fruit or vegetable.  Also, it takes less time than machine juicing; less labor than machine juicing; is the best way to get the highest amount of fiber and nutrients out of fruits and vegetables; and you will use less produce for a higher benefit.

Bottom line, eating fruits and vegetables just as they grow is best.


I really see nothing wrong with it, how about you?
