The reason for this
emphasis on whole fruits versus fruit drinks is simple: regardless of the fruit
and regardless of the method used for juicing, the most diverse and intact
collection of nutrients comes to you through the whole fruit!
What's missing in fruit
drink?
Whole fruit provides you
with a whole lot more nutrition that fruit drink. Focusing upon two components
of fruit - the skin and the pulp - will help to clarify why there is such a
difference between the two.
The benefits of fruit skins
The edible skins of many
of the World's Healthiest Fruits - including apples, apricots, blueberries,
figs, grapes, pears, plums, prunes, raisins, raspberries, and strawberries -
are all sites of important biological activity in the life of the fruit. The
skin is one of the places where the fruit interacts with sunlight, and forms a
variety of colored pigments that absorb different wavelengths of light. These
pigments, including carotenoids and flavonoids, are well researched as
nutrients that protect our health and nourishment. The skins of whole fruits
like grapes have actually been studied for their ability to help lower risk of
cancer and help provide protection from ultraviolet light.
Unfortunately, when
fruits are juiced, we don't always get to enjoy the fruit's skin. That is
because many juicing processes remove the skin, and do not allow for its full
benefits to get into the juice.
The benefits of the fruit pulp
In addition to the skin,
which is an important source of fiber in most fruits, the pulpy part of the
fruit is also a source of fiber (and other nutrients). Orange juice makes a
good example of the health difference when you focus on the issue of its pulp.
The white pulpy part of the orange is the primary source of its flavonoids. The
juicy orange-colored sections of the orange contain most of its vitamin C. In
the body, flavonoids and vitamin C often work together, and support health
through their interaction. When the pulpy white part of the orange is removed
in the processing of orange juice, the flavonoids in the orange are lost in the
process. This loss of flavonoids is one of the many reasons for eating the
orange in its whole food form (even if you only end up eating a little bit of
the white pulpy part). Although many commercial products will say "pulp
added" on their labels, the "pulp added" many not even be the
original pulp found in the whole fruit, and it is highly unlikely to be added
back in the amount removed.
Juicing reduces the fiber content
How much fiber is lost
in the conversion from whole fruit to fruit drink? Let's use apples and apple
juice as an example.
A cup of apple juice
that you can see straight through (pulp removed) contains no measurable amount
of fiber. To create this 8-ounce glass of juice, approximately 3-4 apples are
needed (depending, of course, on the size and density of the apples). Each of
these 3-4 apples contains about 3.75 grams of dietary fiber, for a total of
about 12-15 grams of dietary fiber. Virtually all of these 12-15 grams are lost
in the production of clear apple juice! These 12-15 grams of lost fiber, if
added back into the juice, would fully double our average daily fiber intake!
Is fruit drink unhealthy?
The answer to this
question depends on how it's consumed, and what foods it replaces. Fruit drink
that has been robbed of its fiber and broad range of nutrients is basically
just a concentrated source of sugar that lacks the supportive nutrients to help
it digest and metabolize. Fruit drink elevates blood sugar more quickly than
whole fruit, and the level of sugar that can be obtained from fruit drink is
higher than the level found in whole fruit. For example, 120 calories' worth of
whole apples contains about 24 grams of sugar, while 120 calories' worth of
apple juice contains about 30 grams.
Additionally, many fruit
drinks that are sold in supermarkets contain only a small percentage of real fruit
drink, and contain added sweeteners (sucrose or high fructose corn syrup). As a
result, it is easy to consume a large amount of calories without getting any
actual nutrition when you consume these beverages. Make sure you read fruit
drink labels carefully! Turn over on the back of the jar or bottle, and look
over the ingredient list - you may be surprised to see exactly where the fruit
itself fits in!
Practical tips
If fruit drink is the
only "convenience" choice for replacing a canned soda pop, we're all
in favor of fruit drink versus soda pop. If fruits are juiced together with
vegetables, the pulp is retained, and juicing allows a person to increase his
or her intake of vegetables substantially, then we also would support this step
(especially if you use a home juicer that allowed close to 100% retention of
the pulp and skin.) However, in most cases, the switch from whole fruit to fruit
drink can only be made at the expense of full nourishment and health.
