The Sour Side of Sugar
by Barbara J. Moore, PhD
The year 2009 may prove to be a watershed for
sugar research and policymaking. No fewer
than four important studies have been
published since the beginning of April
examining the effects of sugar-sweetened
caloric beverages (SSBs) on metabolism and
body composition.1-4 The results
of these
studies reveal the damaging effects of sugar
- in liquid form - on human metabolism in
both liver and muscle, and consistently link
higher consumption of SSBs with weight gain
and reduced consumption of SSBs with weight
loss. Several researchers now suggest that
the evidence against SSBs is enough to
justify policy changes such as an excise tax
on soda.1-3,5 An excise tax could
profoundly
affect the health of Americans by reducing
SSB consumption and raising billions of
dollars in revenues to finance obesity
prevention initiatives. The research
discussed below also raises questions about
the insidious effects and questionable ethics
of marketing SSBs to young children and teens
and calls for consideration of warning labels
similar to those now appearing on cigarettes.
It is worth noting that SSBs are not always
defined in precisely the same way in each
study. The broadest definition from a policy
standpoint includes all beverages sweetened
with sugar, corn syrup or any other caloric
sweetener. This would include all
calorie-containing carbonated or
non-carbonated drinks including soda or pop,
sports drinks, energy drinks, juice drinks,
blended sweetened teas and coffee drinks, as
well as sugar-sweetened alcoholic beverages.
The first of the four studies examined data
from more than 3000 children and teens who
participated in the 2003-2004 National Health
and Nutrition Examination Survey
(NHANES).1
After analyzing the diets of these
participants, the researchers concluded that
replacing SSBs with water could save about
235 calories per day. Americans are
consuming 150 to300 more calories today than
they did 30 years ago,6-7 with
approximately
half of those extra calories coming from
SSBs.8 The data from this study
suggest
that replacing SSBs with water would begin to
offset the steady increase in calories that
has occurred over the past three decades.
This would be a significant step toward
reversing the dramatic increase in obesity
that has occurred in the American population
during that period.
The second study supports the idea that
replacing SSBs with water is helpful for
weight loss. This study, called the PREMIER
trial, included 810 adults who participated
in an 18-month diet and lifestyle
intervention.2 A major strength
of this
study was that it controlled for both
physical activity and fitness while assessing
the impact of reducing calories consumed from
sugar. At the beginning of the study,
participants were consuming 356 calories per
day (19% of total energy intake) in the form
of SSBs. A concerted effort to replace SSBs
with non-caloric alternatives produced modest
but significant weight loss.
The remaining two studies show that SSBs can
have harmful effects on metabolism and body
composition by increasing insulin resistance
(a condition that can lead to diabetes),
body mass index or BMI (a marker of overall
fatness), and waist circumference (a marker
of central obesity that is widely considered
a high risk for diabetes and heart disease).
One of these studies3 included
more than
6000 adolescents; the other study4 of
overweight and obese adults was much smaller
since it was a metabolic ward study that
required strict control of dietary intake.
Taken together, these four studies provide
powerful evidence that national policy
changes such as an excise tax on SSBs may be
called for. Such a tax would raise the price
of SSBs and consequently, reduce consumption
and promote weight loss if consumers reach
for water instead. Some proponents have
asserted that an excise tax of one penny per
ounce would reduce SSB consumption by more
than 10% and that support for such a strategy
is strong when people know that the revenues
generated will support obesity prevention
efforts.5
The studies described above suggest that a
reduction in SSB consumption would not only
help stem the growing epidemic of obesity,
but also reduce the prevalence of insulin
resistance and type 2 diabetes that now
afflict a growing number of obese children.
Additionally, we may now have ethical grounds
and a moral responsibility to prohibit the
marketing of SSBs to children and adolescents
in all media, as well as in our nation's
schools. A warning label identifying SSBs as
hazardous to health should also be considered.

Get Out! Outdoor Play for Children and Adults
by Brian Clocksin, PhD
Changes in activity levels, whether we call
it play, physical activity, or exercise are
needed to address rising obesity trends and
to promote personal and social development.
The past 25 years have seen a drastic
increase in obesity levels, mirrored by a
subsequent decrease in physical activity
levels in children and adults. The decrease
in children's physical activity levels is
most evident in out-of-school time.
Historically, out-of-school time was spent
outdoors, routinely in unstructured and
unsupervised play. This generation of
children is spending 25% less time engaged in
outdoor play when compared to their parents'
generation.1
The physical, social, and emotional benefits
of play, and particularly outdoor play, have
been well documented. Unstructured play and
physical activity promote healthy brain
development,2 the development of
social
skills (conflict resolution, negotiating
skills, and group interaction),3-5
curiosity
and self-regulation.6,7 Schools,
however,
are decreasing the time for recess and
physical education,8 in part due to
curricular changes resulting from No Child
Left Behind mandates.9
Young children engage in greater amounts of
physical activity, and at a higher intensity
level, when allowed to play
outdoors.10 For
each additional hour of time outdoors,
children engage in over 20 minutes of
moderate-to-vigorous physical activity
(MVPA).11 Whether our goal is to
combat the
obesity epidemic or promote personal and
social development we need to look at
additional ways to be physically active and
engage in outdoor play.
Strategies for Promoting Outdoor Play &
Physical Activity
- Provide safe access to neighborhood
parks and playgrounds. Access to parks and
playgrounds is highly correlated to physical
activity levels in children. Researchers have
noted that mothers' perceptions of
neighborhood safety also correlated with
physical activity levels in children.1
Parents, teachers and physical activity
advocates can promote physical activity in
outdoor spaces by providing a safe
environment. One study noted an 84% increase
in physical activity levels in children
simply by providing supervised access to
school playgrounds in after-school and
weekend hours. Playgrounds can also serve as
a fun and unexpected workout site for
adults.
- Integrate technology to attract
media-savvy movers. Preschoolers who
participate in less than two hours of media
(e.g., television, computer games, Internet)
per day engage in an average of 30 minutes
more outdoor physical activity than their
peers who utilize media more than two
hours.1
Breaking the attraction to media can be
difficult in children and adults, so look for
ways to integrate technology into outdoor
physical play. With greater access to GPS
technology came the outdoor pursuit of
Geocaching
(IPhone users, there is
an app for that, too!), a treasure hunt using
a hand-held GPS. Many GPS units (and
smartphones) also have a compass built in to
allow for orienteering that can be done in
urban settings or on orienteering courses
across the world. These are great activities
for individuals and families.
- Promoting outdoor play at home and
school. Parents and teachers occupy a great
deal of a child's day. Starting a garden at
home or a gardening club at school is a great
way to integrate learning and outdoor
activity for children and adults. Another
idea is to create a walking
school bus in
which parents pick up school children along a
predetermined route so that the group walks
safely together to school each day. Parents
take turns "driving" the bus. A
walking school bus has been shown to increase
physical activity levels of children and
parents.
There are a number of resources and websites
dedicated to promoting outdoor play and
physical activity. Outdoor play provides an
opportunity to cultivate social
skills,5
reduce stress, and may decrease
"Nature-Deficit Disorder."12
Summer is a
great time
to explore outdoor options, but year-round
adventures await children and adults alike.

Obesity Prevention, Breastfeeding and Swine Flu
The Institute of Medicine and the Centers for
Disease Control and Prevention (CDC)
recommend exclusive breastfeeding for at
least the first six months of life as one of
the key strategies to prevent childhood
obesity. In addition to obesity prevention,
exclusive breastfeeding is recommended for
many reasons that have to do with the good
health of both the mother and baby. For
example, exclusive breastfeeding helps the
mother lose the weight she gained during
pregnancy and it also helps her uterus regain
its muscular tone. For the baby, exclusive
breastfeeding provides maximum transmission
of antibodies that protect against illness,
as well as providing protection against the
subsequent development of obesity.
Some women have expressed concern that if
they get the flu (swine flu or any other
flu), they should stop breastfeeding their
baby for fear of spreading the disease to
their infant. This fear is unfounded.
Breastfed babies resist the flu and other
illnesses and infections better than
bottle-fed babies. So, to protect the baby,
mothers should continue breastfeeding as much
as they possibly can. The CDC has provided
information that parents need to know about
breastfeeding and the flu:
- Breastfeeding and breast milk are
protective against flu viruses because of the
antibodies in human breast milk. Babies who
are NOT breastfed get sick from infections
like the flu more often and more severely
than babies who are breastfed.
- Mothers should continue to breastfeed
even if they suspect or know they are sick
and even if they are taking medicines for
treatment. Mothers should be careful not to
cough on the baby (consider wearing a mask)
and wash hands frequently, but breastfeeding
will heighten the baby's protection.
- If the baby is sick, one of the best
things to do is keep breastfeeding.
Breast milk is better than anything else,
even better than water, juice or
Pedialyte® because it helps
protect the baby's immune
system.

website.
