The
Scary Truth About Sugar
By
Carolyn Dean, MD, ND
While
visiting friends, I bonded immediately with their two-year
old son, Robbie. We played while the adults talked. After
about an hour he got hungry and asked his mother for some
of his favorite food, peanut butter.
Robbie
ate 4 teaspoons straight from the jar and within minutes he
turned into a whirling dervish, a cyclone of hyperactivity.
He was banging his head against a pillow on my lap one minute
and the next tearing down the hall to throw toys around his
room. The parents seemed all too familiar with this behavior
and began making excuses. He gets like this when we have company,
when he's overtired, when he's excited.
As
a doctor, I immediately knew what the problem was-sugar. Robbie's
parents had already figured out that indulging his sweet tooth
lead to hyperactive episodes. But they didn't make the connection
between the peanut butter and the behavior. I took the jar
and showed them the label, which listed two different sugars
(high fructose corn syrup and sugar). The parents were stunned
and said they would be more diligent about cutting out the
hidden sugars in their son's diet. When my husband saw Robbie's
father a week later, he said Robbie was much calmer, was sleeping
better, and was like a different person both at home and at
daycare.
Most
people do realize that sugar can cause hyperactivity, but
what they don't realize is that sugar lurks where you least
expect to find it and affects the human body in myriad ways.
The sugar industry vehemently denies that sugar is hazardous
to human health. Are the parallel increases in sugar consumption,
obesity, and diabetes just a coincidence? Here are the straight
answers.
I
know sugar can lead to weight gain, but is it really all that
bad for me?
Yes, it really is. Sugar is a simple carbohydrate found naturally
in many foods, including fruits and grains. If the only sugar
we consumed were in natural, whole foods, we'd all be just
fine. But the average American diet is full of refined, nutrient-depleted
foods and contains an average of 20 teaspoons of added, refined
sugar every day. That's twice the amount recommended by the
USDA (10 teaspoons and four times the maximum I personally
recommend.)
So
what's wrong with refined sugar? Many things. First, sugar
compromises immune function. Two cans of soda (which contain
24 teaspoons of sugar) reduce the efficiency of white blood
cells by 92 percent-an effect that lasts up to five hours,
according to Kenneth Bock, M.D., an expert in nutritional
and environmental health. Since white blood cells are an integral
part of your immune system, if you happen to meet a nasty
virus or bacteria within five hours of drinking a few colas,
your immune system may be unable to fight off the invader.
Refined
sugar also overworks the pancreas and adrenal glands as they
struggle to keep the blood sugar levels in balance. When you
eat sugar, it is quickly absorbed into your blood stream in
the form of glucose. This puts your pancreas into overdrive,
making insulin (which carries glucose to your cells to be
used for energy) to normalize blood sugar levels. But this
rapid release of insulin causes a sudden drop in blood sugar.
In reaction to the falling blood sugar, excess adrenal cortisone
is stimulated to raise blood sugar back to normal. A constantly
high intake of simple dietary sugar keeps this roller coaster
going and eventually overworks or "burns out" normal
pancreas and adrenal function leading to early menopause,
adult-onset diabetes, hypoglycemia, and chronic fatigue.
The
purpose of eating is to provide your body with nutrients.
But since sugar is devoid of nutrients, the body must actually
draw from its nutrient reserves to metabolize it. When these
storehouses are depleted, the body becomes unable to properly
metabolize fatty acids and cholesterol, leading to higher
cholesterol and triglyceride levels. Drawing on the body's
nutrient reserves can also lead to chronic mineral deficits,
especially in magnesium (a mineral required for more than
300 different enzyme activities) and chromium (a trace element
that regulates hormones such as insulin), putting you at risk
for dozens of diseases, from depression to attention deficit
disorder to asthma.
A
recent study, for example, found that kids who eat significant
amounts of junk food are much more likely to develop asthma
than kids who don't eat junk food. While the researchers didn't
tie asthma to sugar itself, they did point out that a diet
full of candy and other highly processed junk foods is deficient
in a number of nutrients essential to health. And as I explained
earlier, such foods further deplete the body of nutrients
once consumed.
In
fact, children are the biggest consumers of nutritionally
void junk food at a time when their brains and bodies are
growing rapidly and in need of a nutrient-dense diet for proper
development, both physically and mentally. Criminologist Stephen
Schoenthaler has been conducting nutritional studies on delinquents
and public school children for almost thirty years. In a paper
from 1986 he describes how one million kids improved their
test scores when they eliminated sugar and white flour from
their diets.
Alexander
Schauss, Ph.D., a nutritional researcher and writer, performed
similar work in juvenile detention centers and showed that
violent behavior decreased dramatically when sugar was eliminated.
But
I don't eat junk food. Why should I be concerned about my
sugar consumption? Unless you're eating a diet entirely made
of whole, unprocessed foods (think fruits, vegetables, grains),
you're probably eating more sugar than you think, and than
you should. Sugar, in its myriad forms, is added to virtually
every packaged food product you'll find at the supermarket-not
just the sweet stuff. If you drink one soda, even the "natural"
variety, used up your day's sugar allowance.)
Don't
be fooled by the ingredients list. Sugar has hundreds of pseudonyms
(see "Stealth Sugars," for a sampling), and manufacturers
have gotten very good at hiding them from consumers. Because
ingredients are listed from most to least amount, often three
different types of sugars will be in the middle of the list.
If all sugars were required to be listed together, sugar would
be the first ingredient.
To
find out how much sugar you're actually taking in, try keeping
a food diary for one week. Check the labels of the foods you
eat and make note of their sugar content. The reality of the
numbers may not hit home because most of us don't think in
grams-4.2 g of sugar is equivalent to 1 teaspoon of sugar.
At the end of the week, take the total number of sugar grams
and divide it by 4.2 to get your weekly sugar intake in teaspoons.
Then divide that number by 7 to get your daily sugar consumption.
Unfortunately,
the way the FDA's labeling rules are set up, manufacturers
don't have to separate added sugars from naturally occurring
ones on labels. But your total sugar intake will give you
a very good idea of how much added sugar you're eating. Naturally
sweet foods, such as fruit, don't really contain that much
sugar. A cup of strawberries, for example, contains 1/6th
the sugar of a can of cola.
Is
there such a thing as a safe amount of sugar?
Ideally, you should eliminate all refined sugar from your
diet. I'm aware do realize that such a feat may not be realistic
for everyone, particularly since a large number of the foods
you find at the grocery store have been made with refined
sugars (plus the fact that nutrition labels don't have to
list the amount of added sugars a product contains).
Many people subscribe to the bizarre logic that if they overindulge
in sweets and don't wake up the next day with diabetes or
some horrible disease then it must be okay. Dr. Abraham Hoffer,
a psychiatrist in British Columbia who has been studying the
effects of sugar on health for more than 40 years, says that
it takes roughly 15- 20 years of steady consumption of refined
sugar and junk food before an individual develops a chronic
illness like diabetes. And it doesn't take a lot of sugar
to put you at risk. Hoffer's statistics show that once intake
exceeds 20 teaspoons daily, the risk of chronic disease increases
exponentially.
If
you can't completely cut sugar from your diet, due to eating
out and not being in control of ingredients, try not to ingest
more than two or three teaspoons a day. That way you will
stay well below 70 pounds annually (20 teaspoons daily) which
is the cut off point for sugar-induced chronic disease. At
the level we're eating sugar now (20 teaspoons per person
daily), it is only a matter of time before we're facing an
epidemic of sugar-induced diseases. In fact, the epidemics
may have already begun-according to the Centers for Disease
control in Atlanta, the incidence of adult-onset diabetes,
has increased by 70 percent among people in their 30s in the
past 10 years.
What
does processing do to sugar? Processing sugarcane, or any
whole food, strips it of most if not all of its nutritional
value. Researchers found that the refining process of sugar
removes 93 percent of its chromium, 89 percent of its manganese,
98 percent of its cobalt, 83 percent of its copper, 98 percent
of its zinc, and 98 percent of its magnesium. Ironically,
the end product, the refined sugar, is what we consume, while
the nutritious residues are discarded and generally fed to
cattle. In the 1920s, Sir Frederick Banting, the Canadian
medical researcher scientist, who first discovered insulin,
visited Panama to study diabetes among workers in the sugar
cane fields. He could find almost no incidence of diabetes
among the workers who ate the whole sugarcane plant daily.
But among their Spanish employers-who incorporated the refined
end product, white sugar, into their diets-the disease was
rampant.
Is
fructose healthier than sugar? Many people mistakenly believe
that fructose is a healthier sugar-especially since it is
used in many so-called "natural" foods. While there
is a small amount of fructose naturally present in fruit,
the fructose that is added to many commercially prepared foods
is nearly as refined as plain white sugar. Most of the fructose
you'll encounter is in the form of high-fructose corn syrup
(HFCS), which has nearly eclipsed sugar as the most consumed
sweetener in the United States. It is added to thousands of
products, from cola to cookies and even to canned vegetables.
HFCS is a highly refined sweetener that is virtually identical,
chemically speaking, to refined white sugar; during digestion
sugar breaks down into equal parts of glucose and fructose;
HFCS contains 55 percent fructose and 45 percent glucose.
Why
do I crave sugar?
You may crave sugary foods for many reasons. As I explained
earlier, refined sugar stresses the pancreas and depletes
the body's supplies of chromium. A common symptom of chromium
deficiency is sugar cravings. And satisfying these cravings
further lowers chromium and increases cravings. And eating
sweets is just plain pleasurable. Chocolate, for example,
has been found to stimulate the production of serotonin, the
feel-good brain chemical.
But
the human body is drawn to carbohydrates for reasons other
than instant gratification. Carbohydrates are necessary for
metabolic processes in our body. Whole, unrefined carbohydrates
like grains break down into sugar when chewed. After proper
chewing, grains will taste sweet. Grains contain B vitamins
and magnesium, these nutrients are important co-factors in
hundreds of metabolic processes in the body. And the sweetness
of the foods that contain B-vitamins and magnesium may create
a conditioned response to these foods. In other words, sweetness
makes your body think you are getting beneficial vitamins
and minerals. But when we get empty carbs like sugar with
no other nutrients-the body craves more and more to try to
meet its nutrient demands.
So,
if your body needs these vitamins and minerals and is attracted
to carbohydrates to get them, and if instead of a whole grain
you eat a refined empty product, then you will probably keep
craving carbohydrates until you get the vitamins and minerals
you need. That's why many doctors recommend B-complex vitamins
and magnesium supplements help to control carbohydrate addiction.
Of course, eating organic whole grains would be the optimum
solution.
The
main reason for our sugar cravings it that we've had a lifetime
of refined sugar. It's in baby food, snacks and treats at
every turn; Madison Avenue is able to sell 10 cents worth
of junk food for $2.00 because it appeals to our sweet tooth.
We're hooked and we're not complaining as long as the supply
holds out. And as Dr. Hoffer says it's a stronger addiction
than heroin.
Another
cause of sugar cravings is a yeast overgrowth, also known
as candidaisis. Candida is a yeast that is naturally present
in the human body. But some things, such as antibiotics and
too much sugar in the diet, can cause the yeast to multiply,
leading a number of health problems, from vaginal yeast infections
to severe fatigue. And these yeast, when present in abnormally
high numbers, can cause strong cravings for sweet, starchy
foods, causing the problem to perpetuate. (If you suspect
a yeast overgrowth, your doctor can perform a saliva or stool
test for yeast antibodies.) (Dr. Dean is the medical advisor
to yeastconnection.com. Visitors to the site can take the
Yeast Questionnaire to help determine if they have a yeast
problem. If so, a 6-Point Yeast Fighting Program will help
eliminate the sugar and yeast from your life.)
Are
natural sweeteners like honey better than white sugar?
Regardless of what kind of sweeteners you eat, they should
account for no more than 5 percent of your daily calories.
Some natural sweeteners, such as blackstrap molasses, unprocessed
honey, fruit juice, brown rice syrup, and evaporated cane
juice do contain low levels of nutrients, such as the B vitamins,
and minerals such as iron, calcium and potassium. But don't
be fooled, these "natural" sweeteners are only marginally
better than plain white table sugar and dietary intake of
them should be limited.
Sweet
What about calorie-free sugar substitutes such as Nutrasweet
N' Low?
Don't be fooled into switching from sugar to sugar-free substitutes;
they're even more unhealthy, especially aspartame (Nutrasweet).
If you want to add a touch of sweetness without any calories,
try stevia. Stevia is an extremely safe herb that is not only
an excellent sweetener, but it actually lowers blood sugar
levels in diabetics by helping to regulate pancreatic function.
And unlike sugar, which weakens the immune system, stevia
has antimicrobial properties and actually helps the body fight
off colds and flus.
Aspartame
(Nutrasweet), on the other hand, is a neurotoxin
and should be avoided like the plague. Aspartame has been
shown to cause birth defects, brain tumors and seizures and
to contribute to diabetes and emotional disorders.
Aspartame
has three components: phenylalanine (50 percent), aspartic
acid (40 percent) and methanol, also termed wood alcohol (10
percent). Those in support of this popular artificial sweetener,
state that the two primary amino acids, which comprise 90
percent of aspartame by weight, are a harmless and natural
part of our diet. While phenylalanine and aspartic acid are
naturally occurring amino acids, our bodies and brains are
not equipped to handle such high concentrations as found in
a diet soda where they disrupt nerve cell communication and
can cause cell death. The neurotoxic effects of these isolated
amino acids can be linked to headaches, mental confusion,
balance problems and seizures.
Methanol,
too, is naturally present in fruits and vegetables but these
foods also contain ethanol, which neutralizes the methanol.
The Environmental Protection Agency (EPA) defines safe consumption
of methanol as no more than 7.8 mg per day of this dangerous
substance. Yet a one-liter beverage, sweetened with aspartame,
contains about 56 milligrams of wood alcohol, or seven times
the EPA limit. And the absolute irony of the use of aspartame
in diet products is that it can actually cause weight gain.
Phenylalanine and aspartic acid, found in aspartame, stimulate
the release of insulin. Rapid, strong spikes in insulin remove
all glucose from the blood stream and store it as fat. This
can result in hypoglycemia (low blood sugar) and sugar cravings.
Additionally, phenylalanine has been demonstrated to inhibit
carbohydrate-induced synthesis of the neurotransmitter serotonin,
which signals that the body is full. This can cause you to
eat more than your normally would and, ultimately, gain weight.
In one study a control group switching to an aspartame-free
diet resulted in an average weight loss of 19 pounds.
Saccharin
is a petroleum-derived sweetener discovered in 1879 and was
used extensively during the sugar shortages during World Wars
I and II. The sweetener got a bad reputation in l977 when
the FDA proposed restrictions on its use saying studies involving
male rats given large amounts of saccharin developed urinary
bladder tumors. The National Toxicology Program (NTP) then
officially classified saccharin as an "anticipated human
carcinogen." But researchers have since been unable to
reproduce the results from 1977, and saccharin was recently
removed from the NTP's list. Saccharin might be the lesser
of two evils, but it's still a synthetic substance.)
Many
low-carbohydrate foods, like the Atkins Bars, contain sugar
alcohols. What are they?

WHERE
SUGAR RESIDES
USDA recommends limiting added sugars-from packaged foods
and the sugar bowl-to 24 grams a day (6 teaspoons) if you
eat 1,600 calories; 40 grams (10 teaspoons) for a 2,000-calorie
diet; 56 grams (14 teaspoons) for a 2,400-calorie diet; and
72 grams (18 teaspoons) for a 2,800-calorie-diet.

Where
We Get Our Sugar: THEN AND NOW
In 1973, the per capita consumption of sugar and other highly
refined sweeteners (such as high-fructose corn syrup) was
126 pounds a year. Today, it's 158 pounds-an increase of 26
percent. During the same time period, the percent of overweight
Americans increased by nearly 20 percent.
SODA
OVERLOAD
A single can of soda contains 12 teaspoons of added sugars.
That's 120 percent of the USDA's recommended daily intake
of sugar. Researchers have found that just two cans of soda
can suppress immune function for up to five hours.
Originally published in Natural Health Magazine, 2000.
As a physician, I have found that reducing sugar intake is
one of the most important ways to control hypoglycemia, diabetes,
and intestinal yeast. Reduce your sugar intake by supplementing
your tea, water, and other beverages with Stevia. Please go
