[Diabetes-talk] NPR News: Whole Milk Or Skim? Study LinksFattier Milk To Slimmer Kids

And like everything else, medical treatments go through trends. We are
told one thing only to have it changed. Like butter, caffeine, no-carb
diets, low-protein diets, etc. And the beat goes on.

I put the article below on this site to demonstrate the fuzzy-think that
even medical authorities manifest when confronted with something that
doesn't fit their cherished ideas. Note the twin responses of the
pediatrician cited at the end of the article: (1) this *can't* be true
and
(2) the kids were overweight to begin with. Well hello! Aren't these the
kids we're worried about? And note the inability of the "experts" to
admit that people may differ and that, for some, calorie intake may
*not* be totally predictive of energy use.

Parents are currently advised to switch toddlers to reduced-fat milk at
age 2.

Parents are currently advised to switch toddlers to reduced-fat milk at
age 2.

The job of parenting toddlers ain't easy. Consider the 2-year-old to-do
list: Get tantrums under control. Potty train. Transition from whole
milk to low-fat milk.

Speaking from experience, only one of these things was easy.

As my daughter turned 2 in January, we made the simple switch to
reduced-fat milk. Done. Don't need to overthink this one, right?

After all, I'm following the evidence-based advice of the American
Academy of Pediatrics.

The guidance <http://www.pediatrics.org/cgi/doi/10.1542/peds.2008-1349>
is based on studies that found children who consumed low-fat milk as
part of a reduced-saturated-fat diet had lower concentrations of LDL
cholesterol. Given the body of evidence in adults linking high
cholesterol to increased risk of heart disease, it makes sense to keep
an eye on cholesterol, beginning in childhood.

And if you take fat out of milk, you've also reduced calories, which
should help protect kids against becoming overweight. At least, that's
been the assumption.

So here's where things gets confusing. A new study
<http://adc.bmj.com/content/early/2013/02/13/archdischild-2012-302941.sh
ort?
g=w_adc_ahead_tab>  of preschool-aged children published in the Archives
of Disease in Childhood, a sister publication of the British Medical
Journal, finds that low-fat milk was associated with higher weight.

That's right, kids drinking low-fat milk tended to be heavier.

"We were quite surprised" by the findings, Dr. Mark DeBoer
<http://uvahealth.com/doctors/physicians/371>  told me in an email. He
and his co-author, Dr. Rebecca Scharf
<http://uvahealth.com/doctors/physicians/rebeca-scharf> , both of the
University of Virginia, had hypothesized just the opposite.

But they found the relationship between skim-milk drinkers and higher
body weights held up across all racial/ethnic and socioeconomic groups.
DeBoer says their data also show that low-fat milk did not restrain
weight gain in preschoolers over time.

The study included about 10,700 children in the United States. Parents
were interviewed about their child's beverage consumption on two
occasions: once when the children were 2 years old and again at 4 years.
Direct measurements of height and weight (to calculate body mass index)
were taken by researchers.

Interestingly, this is not the first study to point in this direction.

In a 2005 study
<http://www.ncbi.nlm.nih.gov/pubmed/?term=Berkey+Milk%2C+dietary+calcium
+and
+weight+gain> , researchers at Brigham and Women's Hospital reported
+weight+gain> that
skim and 1 percent milk were associated with weight gain among
9-to-14-year-olds.

And a 2010 study
<http://www.ncbi.nlm.nih.gov/pubmed/?term=Huh+milk+adiposity>  by
researchers at Children's Hospital in Boston, which also looked at
preschool-aged children, found that higher intake of whole milk at age 2
was associated with a slightly lower BMI (body mass index). The
researchers concluded that switching from whole milk to reduced-fat milk
at 2 years did not appear to prevent weight problems in early childhood.

When you look at these studies together, DeBoer's findings become more
intriguing, though it's unclear how higher fat could lead to lower
weight.

One theory: It's possible that whole milk gives us a greater sense of
satiety.

"This is speculative," says DeBoer, but if you feel fuller after
drinking whole-fat milk, "it may be protective if the other food options
are high in calories." In other words, if whole-fat milk saves a kid
from eating an extra cookie or a second serving of mashed potatoes, he
or she may end up eating fewer calories overall.

As the authors acknowledge, one of the shortcomings of the new study is
that the researchers did not know how many calories the children were
consuming overall or what types of foods they were eating.

So is it time to think anew about switching toddlers to low-fat milk?

"I don't think there is harm in rethinking a recommendation,
particularly if there weren't rigorous data behind it," says DeBoer. He
says he hopes his results lead to further, more definitive studies.

But not everyone is convinced. "I do think that the recommendation to
give low-fat milk at age 2 is sound advice," says Dr. Stephen Daniels
<http://www.ucdenver.edu/academics/colleges/medicalschool/departments/pe
diat
rics/people/bios/Pages/danielsbio.aspx> , a pediatrician at the
University of Colorado and member of the AAP's Committee on Nutrition.

"I don't think the link between low-fat milk and higher weight makes
much sense from a biological perspective," he says.

Some of the earliest studies evaluating diets low in saturated fat and
cholesterol did find a link to less obesity among girls. And Daniels
points out that in the new study, the toddlers who were on low-fat milk
were already heavier.

"This leaves open the real chance that parents may have been choosing
low-fat milk as a weight-management strategy for those who were already
overweight," Daniels says.

Parents, if this leaves you confused, one thing to keep in mind is that
- whether it's whole, 2 percent or skim - milk is probably not a major
driver when it comes to childhood weight problems. Many studies have
shown that sugar-sweetened beverages play a much bigger role
