Got milk? Overweight kids may need it
Dairy foods appear to cut risk of childhood obesity, study shows
SAN FRANCISCO, California (AP) --Is a glass of milk good for the waistline?
A study finds that despite the calories, youngsters who have dairy food regularly seem to lower their risk of becoming overweight.
Too much weight is now considered to be the most common medical condition of childhood. About 15 percent of U.S. young people are overweight or obese, double the rate of two decades ago.
While the obvious cause is too much food and too little exercise, many studies are attempting to tease apart the precise changes in habits that are driving this health hazard. Several were reported Thursday at a meeting in San Francisco of the American Heart Association.
Lynn Moore, an epidemiologist at Boston University School of Medicine, found that just two servings of dairy food a day are linked to a substantial reduction in adolescent fatness.
Childhood dairy intake has been failing for the last 20 years, in part as youngsters' preferences have switched from milk to soft drinks. During this time, soda consumption has risen by 300 percent.
Another factor, though, has been fat phobia. Youngsters "consume less and less as they get older," Moore said. "Adolescent girls in particular are concerned about eating dairy because they think it will make them fat."
However, her research, based on the Framingham Children's Study, found just the opposite is true. The analysis was financed largely by the National Health, Lung and Blood Institute with additional funding from the National Dairy Council.
Several studies -- including Moore's -- have shown that children and adults who consume adequate amounts of dairy foods have lower blood pressure. Some researchers have put adults on diets with increased dairy and found, to their surprise, that they also seem to lose weight.
In the latest study, the researchers did frequent dietary surveys on 106 families with children and followed them an average of 12 years. They judged body fat by measuring the skin thickness on four parts of their bodies.
They found that those who consumed less than two servings a day averaged about an extra inch of fat in a fold of skin, a surprisingly large amount. The children's average skin fold thickness was 75 millimeters, while those who ate little dairy were 25 millimeters greater.
Dr. Stephen Daniels, associate chairman of the heart center at Cincinnati Children's Hospital, said the benefit was seen with a relatively modest amount of dairy food, and overdoing it could mean large amounts of extra fat calories.
"You shouldn't take home from this that you need to eat as much dairy as you can, but it should be part of an overall healthy diet," he said.
He also noted that no study has yet shown that adding milk to youngsters' diet actually helps them control weight. He said those who get regular dairy foods may weigh less because they eat more home-cooked meals or have breakfast each morning.
Among other findings of Moore's study:
Youngsters who ate moderate amounts of fat -- between 30 percent and 35 percent of total calories (bolding mine) -- weighed less than those who ate either more or less.
Increased consumption of fruits and vegetables was also associated with lower weight.
Contrary to one popular theory, the glycemic index of children's diet -- the amount of fast-burning carbohydrates -- had no bearing on their eventual weight gain.
Just how dairy food might moderate weight gain is a mystery. Moore speculated that calcium or some other nutrient in milk might help influence the way the body stores energy in fat cells. Or perhaps dairy foods simply make children feel less hungry.

Was surprised this hadn't been posted yet.
It's strange that they talk about 30-35% of diet as total fat but don't draw the link to milk, per se, considering the article supports dairy consumption. It's a very narrow window, isn't it? Over or under and you're screwed. Lends some small credence to Sears' Zone theory of 30-40-30, anyway. Anyone here know within 5% how many fat calories they get in a day? I have no clue, personally.
I like the fruits and veggies reminder. It's about as consistent a message as I've ever seen come out of the scientific world.
