This
article is about everything sweet. Learn about the history
of sugar, the difference between refined and natural
sugars, and sugar alternatives (artificial sweeteners).
It
is believed that cane sugar was discovered before the
birth of Christ. As early as 500 B.C., India was said
to have a "reed which gives honey without bees."
This reed would later become known as sugar cane.
The
invasion of Arabs into India nearly 1,000 years later
in 642 A.D. led to the spread of sugar cane to the rest
of the world. The Arabs discovered sugar cane and learned
how it was processed by the Indians. They brought the
cane with them as they conquered much of Europe, introducing
it to lands such as North Africa and Spain. For many
years, however, the rest of Europe was stuck with honey,
because sugar did not make it to the west until the
crusades. The first record of sugar in England occurs
in the year 1099.
Sugar
was brought to the Americas by Christopher Columbus.
At the time, sugar was processed by boiling the cane
juice and then harvesting the crystals left behind after
the water evaporated. These crystals contained protein,
fiber, vitamins, and minerals. While they were calorie
dense, they provided essential nutrients. It was not
until a few centuries later that the process of refining
sugars, and stripping out many of these nutrients, was
perfected and sugar became a profitable industry.
It
is interesting to note that raw sugar is already refined.
Only evaporated cane juice is truly "raw"
sugar (of the cane variety - sugars can come from other
sources as well, such as beets and fruit). Once the
cane juice crystals are harvested, they are washed,
boiled, centrifuged, filtered, and dried. The purpose
of this is to remove all of the original plant materials
(stalk, fiber, etc.) to produce the pure sugar. This
process removes most of the fiber and nutrients that
existed in the original crystals. The sugar then becomes
refined, and is now a food high in calories with little
nutritional value.
Several
centuries ago, refined sugars were expensive to produce,
and were also taxed at a higher rate. Therefore, only
the affluent could afford them. Refined goods became
a symbol of status. People who had access to these foods
were called refined people. Interestingly,
this affluent sector of the population also had a disproportionate
rate of disease and illness as compared to the lower
classes that only had access to unrefined, natural foods.
There appear to be references to the evils of sugar
as early as the 1800s when rations in the military were
compared to standard civilian meals and it was determined
that refined foods had a potentially negative impact
on health.
Sugar
has received a bad reputation lately not just
refined sugars, but all sugars. Many people go out of
their way to avoid sugar in the diet, without understanding
how sugar affects health. Artificial sweeteners are
a common substitute for sugars, but are these synthetic
chemicals truly safe? For many people, sugar-free and
fat-free food is an artificial crutch -
comforted in the knowledge that their food contains
no sugar or fat, they over consume this safe
food. In the end, sugar may not turn out to be the enemy
that many people claim it is.
There
are a few reasons why sugar has a bad reputation. For
one, refined sugars provide easy food for oral bacteria,
and can promote cavities and the accumulation of plaque.
There is also a prevalent belief that all simple carbohydrates
are bad. In reality, the digestive system is very complex
and there is more to consider than just the number of
molecules chained together in a food - one must consider
enzymes, where the food is processed in the body, and
what changes take place to the food before the body
utilizes it.
All
carbohydrates are technically sugar. Before your body
will use the carbohydrate in table sugar, a baked potato,
or a green bean, it must break this carbohydrate down
to glucose, the form of sugar that your body can burn
for energy. Glucose is also stored as glycogen in the
muscle cells. So, since all carbohydrates eventually
end up as a sugar, the mere fact that they begin as
sugars is irrelevant. So what is relevant? The rate
at which the sugar enters the bloodstream, which is
exactly what the glycemic index measures.
Another
concern some people express is the ease
at which sugars are converted to fat. I read one system
for getting into shape that did not offer scientific
evidence, but claimed that in working with extremely
lean body builders, the author figured out that sugars
cause fat to be stored quickly and easily. Other books
simply state that sugar is quickly and easily converted
to fat. Again, we have to understand our biological
systems to analyze those statements. How does a sugar
get stored as a fat? The liver processes the glucose
molecule and turns it into a triglyceride, or fat molecule.
This, again, complicates matters: whether or not you
eat table sugar or a green bean, guess what? By the
time your liver sees it, it has been broken
down to a glucose molecule. There is no practical way
that your liver somehow knows that the glucose
molecule came from a green bean instead of a grain of
table sugar, except that your entire body benefits from
additional nutrients when you consume the green bean.
The
only real way the sugar may be more readily stored as
fat is if it impacts blood sugar or creates some environment
that would promote the conversion of glucose to triglycerides.
Theoretically, a huge surge in blood sugar due to a
rapidly ingested carbohydrate would cause the liver
to convert most of that sugar to fat, regardless of
whether or not you required it for energy.
The
glycemic index demonstrates that refined sugars are
indeed dangerous - they have some of the highest indexes
on the list. Many manufacturers use a complex
carbohydrate called maltodextrin to sweeten shakes.
They can state no sugar or low sugar
on the nutrition label because maltodextrin is a complex
carbohydrate, but it will impact blood sugar more than
table sugar (table sugar is sucrose, which, by the way,
is not a simple sugar - it is two molecules, glucose
and fructose, bonded together). How do natural sugars
fare? Fructose, the type of sugar commonly found in
fruit; lactose, the sugar found in milk; and honey,
the sugar produced from nectar by bees, all fare very
well. In fact, if you are simply concerned about blood
sugar, these three sugars will affect it less than brown
rice, whole wheat bread, and baked potatoes!
Weve
determined that simply avoiding a sugar because it is
a sugar has no real scientific foundation. One problem
with sugars, however, is that many products add an extremely
high amount of sugar to sweetener the products. This,
in turn, causes the product to be higher in calories.
Because consuming more calories means you must expend
more calories to reduce or manage your weight, this
can be of concern. The alternative to using a natural
or refined sugar is to use a reduced calorie sweetener.
There are five major reduced calorie sweeteners on the
market today. These are Acesulfame Potassium (Acesulfame-K),
Aspartame, Saccharin, Stevia, and Sucralose. Are these
products the answer to your woes?
Acesulfame-K
was introduced in 1967. It is 200 times sweeter than
table sugar (sucrose). According to studies, this sweetener
is not absorbed in the body but passes through unchanged.
How many studies? Around 90 studies have been conducted
on this sweetener, with no documented health risks.
The Center for Science in the Public Interest (CSPI),
however, reports that the product can break down to
acetoacetamide. This chemical has been shown to affect
the thyroid in rats, rabbits, and dogs. Administration
of 1% and 5% acetoacetamide in the diet for three months
caused benign thyroid tumors in rats.
Aspartame
was introduced in 1965. It is a low-calorie sweetener
that is also 200 times sweeter than sucrose. Aspartame
is made from two amino acids (the building blocks of
protein): L-phenylalanine and L-aspartic acid. More
than 200 studies have been performed and the only documented
health risks are to people who suffer from phenylketonuria
(PKU), who cannot metabolize the L-phenylalanine. This
is why there is a PKU warning on any product that contains
aspartame. While there are no conclusive, formal, documented
cases of adverse health affects, many people report
headaches after consuming products that contain aspartame.
Other adverse affects that consumers have reported (but
have not been independently verified) include seizures,
dizziness, tremors, migraines, memory loss, slurring
of speech, confusion, fatigue, depression, nausea, and
worse. Because children lack a "barrier" of
protection that prevents the wrong nutrients from entering
the brain (which adults have), some doctors have recently
suggested that aspartame should not be given to children.
Saccharin
was discovered 100 years ago. It is a low calorie sweetener.
It is one of the most studied ingredients in the food
supply. More than 30 human studies have been conducted
with saccharin, and no adverse health effects have been
reported. In 1997, a study using rodents reported a
rise in bladder tumors, although this may be related
to an increase in sodium and other products that were
contained in the experimental diet. The CSPI reports
several studies that may indicate a rise in tumor activity
that correlates to saccharin intake.
Stevia
is a plant that originated in the rainforests of Paraguay.
It is up to 300 times sweeter than sugar, does not impact
blood sugar and has zero calories. The leaves have been
used for over 1,500 years by the Guarini Indians of
Paraguay. It was discovered and introducd to Europe
by M. S. Bertoni in 1899. While Stevia has since become
a very popular sweetener because it is "natural,"
the FDA has yet to approve it as a food source - it
remains classified as a dietary supplement.
Sucralose
is a non-caloric sweetener made from sugar. It was discovered
in 1976. A sugar molecule is modified to replace a hydroxyl
(water) group with a chloride (chlorine) group. This
creates a product on average 600 times sweeter than
table sugar, which theoretically will pass through the
body without being metabolized. Over 100 studies have
been conducted using sucralose in order to approve it
as a food additive.
Are
these sweeteners really worth it? While there are many
anecdotal reports of negative side effects, none of
these have been confirmed through scientific investigation.
In contrast, there is no anecdotal evidence whatsoever
linking consumption of natural sugars such as fructose,
honey, lactose, etc. with cancers, tumors, headaches,
or other problems other than diabetes. Many diabetics
use the glycemic index to control their food intake,
and virtually many natural (unrefined) sugars fall within
acceptable ranges for consumption based on those guidelines.
Do
sugar free foods really help to control calories? I
know many people who will avoid sugar like the plague,
then purchase a box of sugar-free brownies and eat the
entire box. What are they trying to achieve? Sugar-free
may imply reduced calorie but when you over
consume reduced calorie foods, you still create a problem!
Do sugar-free brownies fit into a lifestyle, or are
these a quick fix?
Adding
one teaspoon of natural sugar to a bowl of oatmeal will
add four grams of sugar or 16 calories and barely impact
the rate at which that food is digested and released
to the bloodstream (remember, your liver wont
know if the glucose molecule it is processing came from
the oatmeal or the teaspoon of sugar). Remember the
glycemic load? This would have a low load! Adding one
teaspoon of an artificial sweetener wont add any
calories - but will introduce a new realm of possible
side effects. On the other hand, if you avoid healthy
food choices such as fruit due to the sugar content,
you also miss out on thousands of vitamins, minerals,
and phytochemicals that dont exist in any tablet
or pill on the market - and have documented health benefits
rather than risks! Oranges can reduce the risk of stroke.
Bananas promote heart health by providing a tremendous
amount of natural potassium. The list goes on and on.
What
sugars are considered natural? A few natural sweeteners
include: stevia (a herbal extract that is naturally
sweet with no calories), barley malt, evaporated cane
juice before it is refined (refined sugar is derived
from cane juice, but is extremely processed with many
of the natural enzymes, vitamins, minerals, and fiber
removed), fruit juice (fructose), rice syrup, honey,
and sugar alcohols. All-natural maple syrup is not only
flavorful, but rich with iron and other micronutrients.
Sugar alcohols have a sweet taste but are
processed by the body as alcohol. This means that they
are typically burned for energy and have a minimal impact
on insulin and blood sugar, according to the latest
studies. They are not known to be toxic like non-sugar
alcohols.
I
also recommend a product called Sucanat® that contains
sugar cane molasses.
There
is some confusion about what high fructose corn syrup
(HFCS) actually is. You will find that the majority
of processed foods contain this as a main ingredient.
It is difficult to find bread in the supermarket that
isnt made with HFCS, and most sodas, treats, and
non-natural juices contain this as well. HFCS is much
sweeter than table sugar, which is one reason for its
popularity in the food industry. HFCS can be misleading
to consumers who are aware of natural sugars and the
glycemic index. Knowing that fructose is a natural fruit
sugar and low on the glycemic index, they may assume
the HFCS falls under the same category. HFCS is actually
hydrolyzed cornstarch, which means that cornstarch is
mixed with enzymes and broken down. A chemical in the
cornstarch converts some of the sugar in glucose form
to fructose. The end result only contains 14% fructose
- the rest is dextrose and other sugars and carbohydrates
(so it is hardly high fructose, it is only
higher in fructose than other corn products).
HFCS has a glycemic index of 89, which is only slightly
less than that of table sugar (92). In contrast, milk
sugar (lactose) is 65 and natural fructose is 32, or
almost 1/3 that of HFCS.
Sugar
is certainly not your enemy. Refined and processed sugars
are! Consume a protein and a whole, unprocessed carbohydrate
with every meal, and add healthy fats to your diet.
If these meals happen to contain some natural honey
or cane juice, dont sweat it! Eat 4 - 5 servings
of fruit and or vegetables each day - there are far
too many healthy compounds in these foods to pass them
up out of fear of the natural sugar contained within.
Make your own choice about artificial sweeteners, but
keep in mind that you can easily control your portion
sizes and use natural sweeteners instead. Are the potential
risks worth the small benefit you may or may not be
receiving from artificial sweeteners? Learn to let sugar
work with you, not against you!
