Some people say the government is partly to blame for America’s obesity problem – because of the federal dietary guidelines. Julie Grant reports on efforts to improve how the government offers nutritional advise to Americans.

You’ve probably seen those colorful food pyramids they put out, the ones that tell you how many servings to have of each kind of food each day. Those recommendations are used by schools, nursing homes, and the federal food stamp program to design menus.

Robert Post works with the U.S. Department of Agriculture, which puts out the food pyramid.

“IT’S THE CORNERSTONE FOR BUILDING HEALTHY EATING PATTERNS. CHOOSING THE RIGHT AMOUNTS OF FRUITS, VEGETABLES, GRAINS, MILK PRODUCTS, AS WELL AS PROTEIN SOURCES SUCH AS MEAT AND BEANS.”

Post says people need to know how to get all the nutrients they need, without over-indulging in foods they don’t need.
That’s why the guidelines also set specific limits on things like salt and fat.

But some researchers think the guidelines actually have the potential to cause harm.

Paul Marantz is professor of epidemiology and population health at the Albert Einstein College of Medicine.
He doesn’t think the guidelines should give specific recommendations about how much fat and salt people should eat.

“THOSE SEEM TO CARRY PRECISION THAT IMPLIES THAT WE HAVE A GREATER DEPTH OF KNOWLEDGE THAN WE ACTUALLY DO, SO PICKING THESE NUMBERS AND REQUIRING THAT PEOPLE HUE TO THESE GUIDELINES IS A PROBLEM.”

Marantz says even a little bit of error in the food guidelines can have a big public health effects.

He and his colleagues wanted to find out the potential impact of past dietary guidelines.

They looked at 1995, when the nutritionists were telling people to avoid fat.

“MOST OF US REMEMBER IN THE OLD FOOD PYRAMID THAT MADE IT QUITE CLEAR THAT THE MOST IMPORTANT THING TO AVOID WAS FAT AND ONE COULD EAT GRAINS AND PASTA AND BREAT AND THE LIKE WITHOUT CONCERN.”

Marantz says Americans did eat more pasta and bread – that added lots of calories, and lots of weight.

His research, which was published in the American Journal of Preventive Medicine, found what Marantz calls a ‘strong correlation’ between the dietary guidelines against fat and obesity in Americans:

“CORRELATION IS BY NO MEANS CAUSATION. WE CANNOT INFER FROM THIS THAT IT WAS BECAUSE OF DIETARY GUIDELINES THAT WE ARE EXPERIENCING THE EPIDEMIC OF OVERWEIGHT AND OBESITY. BUT THE CONNECTION IS STRONG.”

Marantz wants the government to give general advice for healthy eating, but not specific guidelines. He gives the example of sodium. Marantz says no one really knows how much salt is appropriate for each person. But there’s a push to put specific limits on sodium in the new guidelines.

Robert Post of the USDA says anything that gets into the 2010 recommendations will be based on what he calls the Gold Standard of scientific evidence. He says a committee of nutritional experts has been meeting for two years to create the new guidelines…

“WE CAN BE ASSURED THROUGH THIS VERY INTENSIVE REVIEW OF SCIENCE AND THE WEIGHT OF THE EVIDENCE IT PROVIDES THAT THE CURRENT ADVISE ON CARBOHYDRATES FOR EXAMPLE IS BASED ON THE LATEST RESEARCH.”

Post says any recommendations for fat and sodium will also be based on the preponderance of current science. The committee is expected to make its recommendations this summer, and new dietary guidelines should be published by the end of the year.

Birds Springing North Too Early

Some migratory birds are heading North earlier
because of climate change. That’s causing problems for
some bird species. Lester Graham reports:

On their way north, the migratory birds check things out at each stop along the way. If
the leaves are budding and the days are warm, they keep going north. But because of
climate change they’re getting to their breeding grounds a lot earlier.

Johannes Foufoloupolus is a researcher with the University of Michigan. He says, for
example, in the Rocky Mountain region, robins are arriving early. And when they go to
their highland breeding grounds, there’s still snow on the ground.

“A robin eats worms and it can’t really tunnel through six feet of snow to get to the
worms. So, that might be a problem.”

Other birds arrive early to find one of their main sources of food, insects, are not
emerging yet. What makes it worse, in some species the females like to hook-up with
males who get to the breeding grounds early. But with not as much food and cold
snaps, it means some baby birds are not surviving as well.

The Call of the Shore

Now that it’s summer, many of us long to be by the shore. Great Lakes Radio Consortium
commentator Bob Hamma nurtures a dream of a lakeside cottage, but reflects that
he really wants something more than ownership:


I often dream of owning some land on the shore. Living less than an hour from Lake Michigan,
I think it would be wonderful to have a place to go to, not just in the summer, but throughout the year,
a place where the ever-changing patterns of the lake and dunes can become a part of me.


I remember reading a comment by the Native American writer Brenda Peterson about her love
for Puget Sound in Washington, “I may never own land even if one day I might afford it.” Her words
challenge me.


What do I really want? Is it a cottage with a view? A private beach? No, what I long for is
not ownership, but the opportunity to let the call of the shore sink more deeply into my soul.


Being at the shore fosters a certain quality of attentiveness to life, an ability to live in the present
moment. Perhaps it’s the fact that things are always changing there, yet in another way, they are always
the same. The color of the lake, the size of the waves, the strength of the wind, the patterns of the
clouds-all these change from hour to hour. Yet the lake is always there-timeless-almost awaiting
my return.


It’s as if it were calling me to take some time away from my life and gain a new perspective. But the
shore is not just a place of retreat. It is a place of encounter, where life’s incredible complexity, its constant
struggle, its subtle rhythms are ever present for one who looks. The call of the shore is an invitation to live
in the present, to see life each day in its richness and diversity.


I don’t need a cottage for that. I simply need to be there, to put some time aside and go. But it’s
a struggle to respond to that call, to break away from the busyness of my life. Indeed, the issue is not
whether the lake belongs to me, but whether I belong to it. To truly belong there, I must listen to its call,
I must be long there.


I can’t promise that I’ll never own a piece of the shore, but for now, I’ll try to practice the kind
of attentiveness to life that it calls me to. This way, if by some amazing luck I can afford it, I’ll be ready.

way of the Great Lakes Radio Consortium.

Meditation in a Labyrinth

Throughout history, people have looked to nature to help them achieveinner- peace. Whether it’s a walk in the woods, gazing at the stars, ordaydreaming out a window – natures often been the inspiration. And nowan ancient tradition is making a comeback.
