Nurse Jen is taking the summer off to spend quality time with her lovely daughters.
She is keeping her brain active by doing some writing for the blog on some interesting topics.
Here is Jen's first contribution.
Summer is officially here and many of us are planning out of town visits with
friends and family. Ice cream at the pool, cookies and juice at a doting
grandparent's house and a general lapse in regular healthy eating routines all
spell out an increase in SUGAR INTAKE. While the occasional sweet is nothing to
get worked up about (in fact, eliminating altogether will probably only make
your child want sweets more) a lot of media attention has been paid to sugar
lately. Although there are a lot of conflicting opinions about sugar out there,
below you will find my summary of today's 'sugar buzz.'
If you're short
on time, I start by listing the current recommended levels of how much sugar
kids can consume. If you're inspired to read more, read on (additional reading
suggestions are listed below.)
So what do we know NOW about how much kids
can consume?
Preschoolers with a daily caloric intake of 1,200 to 1,400
calories shouldn't consume more than about 4 teaspoons (or 16 grams) of ADDED
sugar a day. Children ages 4-8 with a daily caloric intake of 1,600 calories
should consume no more than about 3 teaspoons of ADDED sugar a day
(approximately 12 grams.) In order to accommodate all the nutritional
requirements for this age group, there are just fewer calories available for
discretionary allowances like sugar. (

education.com)
As your child grows into his pre-teen and teen years, and
his caloric range increases to 1,800 to 2,000 a day, the maximum amount of added
sugar included in his daily diet should be 5 to 8 teaspoons (approximately 20-32
grams). (

Keep
in mind when you're reading labels, four grams of sugar equals one teaspoon of
granulated sugar.
What are Added Sugars?
Added sugars are sugars and
syrups that are added to foods or beverages during processing or preparation.
They do not include naturally occurring sugars such as those found in milk
(lactose) and fruits (fructose). Added sugars (or added sweeteners) include
natural sugars (such as white sugar, brown sugar and honey) as well as other
caloric sweeteners that are chemically manufactured (such as high fructose corn
syrup.) (American Heart Association, 2013).
How can I tell by looking at
a Nutrition Facts panel if a product has added sugars?
Unfortunately, current
nutrition labels don’t list the amount of added sugars (alone) in a product. The
line for “sugars” you see on a nutrition label includes both added and naturally
occurring sugars in the product. Naturally occurring sugars are found in milk
(lactose) and fruit (fructose). Any product that contains milk (such as yogurt,
milk, cream) or fruit (fresh, dried) contains some natural sugars. (AHA,
2013)
But you can read the ingredient list on a processed food’s label to
tell if the product contains added sugars. Names for added sugars on labels
include:
Brown sugar
Corn sweetener
Corn syrup
Sugar molecules
ending in “ose” (dextrose, fructose, glucose, lactose, maltose,
sucrose)
High-fructose corn syrup
Fruit juice
concentrates
Honey
Invert sugar
Malt sugar
Molasses
Raw
sugar
Sugar
Syrup
And what are we really consuming?
A study
conducted by the AHA found children as young as 1-3 years already bypass the
daily recommendations, and typically consume around 12 teaspoons of sugar a day.
By the time a child is 4-8 years old, his sugar consumption skyrockets to an
average of 21 teaspoons a day. The same study found 14-18 year old children
intake the most sugar on a daily basis, averaging about 34.3 teaspoons. In
general, a statement from the National Health and Nutrition Examination Survey
conducted from 2001-2004 found the average American consumes the equivalent of
22.2 teaspoons of added sugar. That is about triple the recommended adult
amount! (
www.family education.com)
There
is more added sugar in our food today so it is important to read labels- and
look at your child's plate! Have you seen the myplate picture that replaced the
nutrition pyramid we grew up with? Keep it in mind every time you make your
child's plate. (
www.myplate.gov)
An
interesting fact
In 1822 Americans consumed the amount of added sugar in one
12-ounce can of soda every five days. Today we consume that amount every ten
hours...which is equivalent to 12 cans of soda in five days. ("Are we too
sweet?," 2012).
If you'd like to learn more....
Sugar Crusader Dr.
Robert Lustig's recent book Fat Chance has received a lot of attention ( we have
an office copy if you'd like to borrow it.) Lustig’s name probably sounds
familiar - more than 3.6 million people have watched his 2009 viral YouTube
mini-series Sugar: The Bitter Truth.
Dr. Lustig is Professor of
Pediatrics in the Division of Endocrinology at UCSF and Director of the UCSF
Weight Assessment for Teen and Child Health (WATCH) Program. He is nationally
recognized in the field of pediatric neuroendocrinology and a leading expert on
childhood obesity.
Lustig investigates not just the detrimental
biological effects of consuming sweets. He is also interested in identifying how
hidden sugars find their way into our diet and how our society's sugar
consumption has contributed to declining health in the general population, not
just among those who are classically obese. (Hoffman, 2013).
Why is
sugar so bad for us?
The easy and widely accepted answer is that refined
sugar and it's popular substitute high fructose corn syrup (H.F.C.S.) don’t come
with any protein, vitamins, minerals, antioxidants or fiber, and so they either
displace other more nutritious elements of our diet or are eaten in addition to
what we need to sustain our weight, which is why we get fatter. Lustig (and
some biochemists) argue, however, not about the consumption of empty calories.
They state that sugar has unique characteristics, specifically in the way the
human body metabolizes the fructose in it, that may make it harmful on its own,
at least if consumed in sufficient quantities. (Taubes, 2011).
To
simplify this theory, Gary Taubes of The New York Times writes "the fructose
component of sugar and H.F.C.S. is metabolized primarily by the liver, while the
glucose from sugar and starches is metabolized by every cell in the body.
Consuming sugar (fructose and glucose) means more work for the liver than if you
consumed the same number of calories of starch (glucose). And if you take that
sugar in liquid form — soda (or fruit juices) — the fructose and glucose will
hit the liver more quickly than if you consume them in an apple (or several
apples, to get what researchers would call the equivalent dose of sugar). The
speed with which the liver has to do its work will also affect how it
metabolizes the fructose and glucose."
The last time an agency of the
federal government looked into the question of sugar and health in any detail
was in 2005, in a report by the Institute of Medicine, a branch of the National
Academies. The authors of the report acknowledged that plenty of evidence
suggested that sugar could increase the risk of heart disease and diabetes —
even raising LDL cholesterol, known as the “bad cholesterol”—– but did not
consider the research to be definitive. (Taubes, 2011).
Currently, the
National Institutes of Health are supporting surprisingly few clinical trials
related to sugar and high-fructose corn syrup in the U.S. All are small, and
none will last more than a few months. Lustig and his colleagues at U.C.S.F.
are doing one of these studies. It will look at what happens when obese
teenagers consume no sugar other than what they might get in fruits and
vegetables. Another study will do the same with pregnant women to see if their
babies are born healthier and leaner. (Taubes, 2011).
So what to eat?
Lustig says (in his January interview with Oprah Magazine) "Real food!
That's it. If it came out of the ground, or it's from an animal that ate what
came out of the ground, you're good to go. But if a human processed it in
between, either something was added, usually sugar, or something was removed,
most likely fiber and micronutrients like vitamins and minerals. The key for
most people is reducing insulin, and to do that, you have to put back fiber into
your diet and cut back on refined carbohydrates and sugar. If you're buying food
that has a nutrition label, it's been processed. And if any form of sugar is one
of the first three ingredients, consider it a dessert. When I was a kid, we had
dessert once a week. Now we have it once a meal, and it's almost always
processed. That's the problem. " (Schomer, 2013).
Is sugar as bad as
Lustig claims is?
The answer is......it could be. It very well may be true
that sugar and high-fructose corn syrup, because of the unique way in which we
metabolize fructose and at the levels we now consume it, cause fat to accumulate
in our livers followed by insulin resistance and metabolic syndrome, and so
trigger the process that leads to heart disease, diabetes and obesity. They
could indeed be toxic, but they take years to do their damage. It doesn’t happen
overnight. Until long-term studies are done, we won’t know for sure. (Taubes,
2011).
In the meantime, I suggest you try your best to stick with the
AHA current guidelines and practice the delicate balance of limiting your
child's sugar intake without making it into a major battle. Good
luck!
