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.

A Consumer Reports study finds
most of the chickens bought at
the grocery store are contaminated
with bacteria that can cause you
to get sick. Lester Graham reports:

Consumer Reports bought whole chickens from 100 different stores.

Dr. Urvashi Rangan says they tested them for two different strains of bacteria.

“Salmonella and campylobacter infections can give people serious diarhea, abdominal cramping for sometimes days, even weeks at a time.”

Two-thirds of the chickens they tested were tainted.

Rangan says the U.S. government’s guidelines are pretty loose for the chicken processors.

“Each company is basically allowed to script their own hygeine plan. And, clearly, there aren’t enough standards or standardidization among them that has allowed them to achieve a decent rate of cleanliness.”

The chickens that were cleanest were organic air-chilled chickens. The Consumer Report’s study is available online and will be published in the January issue of the magazine.

Developing New Test for Deer and Elk Disease

Chronic Wasting Disease is killing wild deer and elk. And it’s slowly spreading to new areas in North America. Right now, tests for the disease are done after the animals are dead, but researchers say they might be getting closer to a test that can be given to live animals.

Chronic Wasting Disease is killing wild deer and elk. And it’s slowly spreading to new areas
in North America. Right now, tests for the disease are done after the animals are dead,
but researchers say they might be getting closer to a test that can be given to live animals.
The GLRC’s Christina Shockley reports on what this might mean in the fight against the disease:


Chronic Wasting Disease, or CWD, causes deer and elk to waste away and die.
The disease is causing hunters and wildlife officials to worry about the
future of the wild deer population. Right now, testing a brain sample from a
dead animal is the sure-fire way to detect the infectious protiens, called prions, that
cause the disease.


Alan Young is a Veterinary Science professor at South Dakota State University.
He’s developing the new test.


“Our ultimate goal is basically to develop a test for infectivity in blood,
by taking a blood sample, and then analyzing for the presence of the infectious prion protein.”


Young says a blood test would let deer and elk farmers know if their herds are
infected before the animals die. He says the research could also lead to a cure for CWD.

MARKETING a BY-PRODUCT OF ETHANOL (Short Version)

In the next six years, the amount of ethanol production is expected to double. With more corn ethanol plants coming online, the distillers are looking for ways to sell one of the by-products.
The GLRC’s Lester Graham reports ethanol distillers are selling the corn mash left over from turning corn into ethanol:

In the next six years, the amount of ethanol production is expected to
double. With more corn ethanol plants coming online, the distillers
are looking for ways to sell one of the by-products. The GLRC’s
Lester Graham reports ethanol distillers are selling the corn mash
left over from turning corn into ethanol:


The mash, called distillers grain, is a good livestock feed. It’s
higher in protein than the same amount of corn. Since most of the
ethanol plants are being built in the corn-belt, the distillers are
trying to get nearby livestock operations to buy the distillers grain.


Jim Hilker is an agriculture marketing expert at Michigan State
University. He says that works… up to a point…


“It depends on whether the livestock is near. It appears, as many
plants are going up, that we’re going to saturate some areas. They’ll
have to be shipped somewhere.”


That means drying the distillers grain… and shipping it… both adding
to the cost. The trick is to keep the price the same or cheaper than
corn… to keep it competitive. With 97 plants operating and another 34
under construction to meet the government’s call to produce a lot more
ethanol… there could soon be a glut of distillers grain.

Recent Deer Hunts Help Feed the Poor

  • Overpopulation of deer is causing problems for forest understory, farmers, and increased car/deer accidents. Some programs are encouraging hunters to take an extra deer and donating the meat to charity. (Photo by Lester Graham)

The hunting season for deer has ended or is about to end in most states. But the deer are still plentiful. Overpopulation of deer has led to an increase in deer-and-car crashes. Too many deer also damage the understory of forests. In some states, though, the deer overpopulation also means more deer meat is made available to low-income people. That’s because hunters, meat processors and food banks are working together to get venison to the poor. The Great Lakes Radio Consortium’s Skye Rohde
reports:

The hunting season for deer has ended or is about to end in most states. But the deer are
still plentiful. Overpopulation of deer has led to an increase in deer and car crashes. Too
many deer also damage the understory of forests. In some states, though, the deer
overpopulation also means more deer meat is made available to low-income people.
That’s because hunters, meat processors and food banks are working together to get
venison to the poor. The Great Lakes Radio Consortium’s Skye Rohde reports:


It’s only been in the last decade or so that states have begun allowing hunters to donate
wild game to charitable organizations. In New York, meat processors and hunters started
the Venison Donation Coalition in 1998. Starting out, they gave a thousand pounds of
deer meat to food pantries in two counties.


Kathy Balbierer handles the coalition’s public relations. She says since that first thousand
pound donation, the program has grown…


“Last year, we had 108,000 pounds of venison donated, which on the average is, you
know – a deer is 40 pounds. It was approximately 27,000 deer. This year we have 119
participating processors throughout the state serving 52 counties.”


It’s an idea that hunters and meat processors across the nation are embracing. There are
venison donation programs in almost every state. Some, such as those in New York and
Illinois, are administered by state government. Others, like Michigan’s and Minnesota’s,
are run by private organizations.


Here’s how it works. First, a hunter who wants to donate meat takes it to a participating
processor. Ed Tanguey operates a meat processing facility in Kirkville, New York. He
says it’s a pretty simple process.


“Once the hunters show up to the building, we’ll have them come into our skinning room.
We’ll have them fill out some paperwork and once it’s brought in, we’ll start to skin the
deer, remove the hide and trim off any meat that’s not edible. We’ll bring the deer into
our cutting room.”


Butchers section the deer into shoulder, torso and hindquarters.


(sound of grinder starting up)


Then Tanguey sets up the grinder and grabs the meat from the cooler.


He packs the ground meat into five-pound black-and-white tubes and slaps a label on
with his name and the hunter’s license number on it.


Tanguey has processed 250 deer so far this season, 44 of them for the Venison Donation
Coalition. The coalition pays him a reduced rate, about a dollar a pound. Once there’s
enough meat in Tanguey’s cooler, he calls the Food Bank of Central New York to pick it
up.


Tanguey says this is his way of giving back to his community.


“When I see a hunter bringing in his son or grandson and they’re giving a second deer or
a third deer to the food bank, I think it’s going to pass it on to them. And years from now
we’ll keep the coalition supplied with some more food for the food bank.”


Jim Giacando is operations manager at the Food Bank of Central New York. He says
200 of the 600 agencies he works with ask for venison.


“In our freezer, we have almost 1,000 lbs ready to distribute, and it’s already committed
to a number of agencies throughout our 11-county area. And we’ll be distributing it this
week and next week, and then hopefully we’ll receive more in and fill more orders.”


The food bank will receive venison up until January. But Giacando says the greatest
challenge is keeping up with the demand for deer meat. A lot of people want it.


“I think we actually may have to get to a point where we might have to say ‘you know,
you can’t order that much. We have to keep it for all the other programs.'”


(ambient sound in church)


One of the food pantries asking for the deer meat is the University United Methodist
Church in Syracuse, New York. Norma Goel ordered venison from Giacando’s food
bank. The church’s food pantry feeds about 150 people every week.


Goel says she can’t buy as much food for the pantry as she’d like to because of the
church’s limited budget and an increase in the number of poor people asking for food.
She says farm-raised meat is a high-priced commodity…


“We’re always looking for a way to provide meat to participants in the pantry. And it’s
become increasingly difficult to buy frozen meat that the food bank has. By and large,
we’re not purchasing frozen meat from the food bank because we can’t afford it.”


So the deer meat is a cheaper alternative. Last year, Goel ordered venison too late to
receive any. This year she got all she could for the pantry: 60 pounds. She only has to
pay the handling costs – the coalition covers processing.


Goel says she’ll encourage people to use the deer meat in place of ground beef because
it’s high in protein and low in fat. She says the 60 pounds will feed a lot of hungry people
in her community.

You might have tried hazelnut flavoring in your coffee. And we all know about the hazelnuts in
European chocolate bars. Hazelnuts – or filberts – are traditionally grown in Turkey, Italy, and
Oregon. Now, researchers are developing varieties that could thrive in more challenging
climates, such as the Great Lakes region. A man in northern Minnesota is growing hazelnuts. It’s
part of his attempt to live off the land. And he says hazelnuts are the perfect crop for a future of
global climate change. The Great Lakes Radio Consortium’s Stephanie Hemphill visited his
farm:


John Munter lives on 40 acres of hay fields and woods. He and his wife and their four children
live in a ranch-style house in the middle of the fields. Munter works at a Northwest Airlines
reservation center. But his heart is here at the farm. It was settled by his grandfather, a Finnish
immigrant, 90 years ago.


Munter has a full beard. He wears round wire-rimmed glasses. And when he goes out to do the
chores, he puts on a fraying denim jacket that must be 50 years old. It belonged to his great-
uncle.


(sound of Munter walking outdoors)


“Here’s our maple sugaring operation… this is the garden here, you can see it’s pretty small.
We’re so busy it’s hard to spend a lot of time gardening… and to my right is the log sauna…”


John Munter has a lot of projects. He wants to be as self-sufficient as he can on the farm.


Twelve years ago he planted some hazelnut bushes south of the old farmhouse. They’re protected
from the north wind here, and they’ve grown to about seven feet tall.


This is a new crop for northern Minnesota. There are wild hazelnuts growing around here, but no
one had tried the newer varieties, that are bred to produce more and bigger nuts.


Four years ago, Munter’s bushes began producing nuts. He’s especially happy with one of the
bushes.


“It really just pounds out the nuts. They’re not real big, but they’re plentiful, last year we got
maybe two pounds of nuts from this little bush right here… Now this bush here produces nuts
early. They’re a signal to me because when the squirrels start attacking my nuts, they take after
this one first because they ripen earlier. You can see a bush loaded with hazelnuts, and the next
morning it’s stripped. And then they go to the next bush, and the next one, and so on. (Hemphill:
‘Then how do you get anything out of them?’) Well, I’m letting the animals have them at this
point, because I’m too busy with all my other projects to process all these little nuts.”


You have to take the long view with hazelnuts. Right now, these bushes are 12 years old, and
they’re just beginning to produce nuts. But Munter says in ten years, he could get hundreds of
pounds.


He could sell them to candy-makers, or just eat them. They’re high in protein and vitamins. And
Munter says the oil is as healthy as olive oil. Most hazelnuts come from Europe and Oregon.
John Munter is determined to show they’ll grow in northern Minnesota.


“They’re great for climate change too. Because they bend and don’t break… in hurricanes,
tornadoes and wind storms, whatever… if a forest fire burns it over, they’ll pop back up from the
base there.”


John Munter says hazelnuts could be an important source of food if the climate gets harsher.


Munter’s not the only one in the Great Lakes region trying out hazelnuts. Some researchers say
they’re the crop of the future. They say the bushes are better for the environment than corn and
soybeans.


Hazelnut bushes stay in the ground for years, so the soil isn’t eroded by plowing. And they’re
very good at absorbing fertilizers. That means excess fertilizer doesn’t run into nearby streams.


A few farmers are planting them, and thinking of switching gradually, from corn and soybeans, to
hazelnuts.

Farming in Age of Global Warming

For years, scientists have been studying what will happen to
our environment in the age of global warming. A recently
released report draws some conclusions about what may
happen in the farm fields. The Great Lakes Radio Consortium’s
Bill Cohen reports:


More carbon dioxide in the air will bring larger crop yields, says
plant ecologist Peter Curtis of Ohio State University. He and other
OSU scientists have just finished reviewing 159 studies from the past
20 years on global warming. Their conclusion – by the end of this
century, some plants will produce more grain.


“Corn, for example, about 5%, wheat we’re lookin’ at about 15%, barley
a little bit more – maybe 18%, soybeans at around 20%, and then rice
all the way up around 40%.”


More food, says Curtis, but it might be less nutritious. That’s the
downside his study is predicting if global warming continues – the
crops will contain less nitrogen and that may mean less protein for the
humans, cows, and pigs that eat it.

Engineering a Cleaner Pig

Like most farmers, hog farmers have seen a shift from small, family-owned farms, to large-scale hog operations, but more pigs on less land creates some major environmental problems – especially, what to do with all that manure. Bio-tech researchers in Canada believe they have created an animal that will help. The Great Lakes Radio Consortium’s Mark Brush has more:

Cattle that love to eat thorny shrubs and nasty weeds are proving they can clean up areas infested with invasive plant species. The Great Lakes Radio Consortium’s Mary Jo Wagner reports.


For years, land managers have been trying to find better ways to control particularly troublesome plants. Invasive species such as multi-flora rose, prickly ash and wild parsnip used to be held in check by natural fires, or grazing by bison and elk. But ever since wildfires have been mostly controlled, and elk and bison populations have plummeted, many invasive species in the Great Lakes region have been growing out of control. So researchers have been looking for other ways to fight these invaders. At the University of Wisconsin, researchers have been testing Scottish Highland cattle on some fields containing invasive species. Consultant Martha Rosemeyer says the preliminary results look promising…


“One of the things we’ve found out by following the cattle is they really like wild parsnip when it’s young. Out of a field of grass they’ll identify and hone in on the wild parsnip and eat the whole patch of it.”


One of two farms testing the cattle’s weed eating potential is owned by Peter Rathbun. He says on one of the test plots, the parsnip was so high and thick, biologists wouldn’t go in to take samples.


“I was a little concerned, well are the cows going to go in and eat it and get sick, but they went in and ate it and they loved it.”


Rathbun has various weed and brush problems or “junk” as he calls it on 120 acres, including prickly ash, hawthorn, gooseberries and other plants that produce large thickets. He was one of the first farmers in Wisconsin to start raising the highland cattle several years ago and now has around forty animals eating weeds on half his farm. His goal is to return some o the land to its original oak savannah status. So far on his fifteen test plots with and without cattle, the results of grazing Scottish cattle are positive.


“It’s so wonderfully obvious what’s happening because here’s three strands of electric fence. On one side you can walk right through the woods…its no problem – you can see everything there. On the other side it’s dense, you don’t even want to think about walking through it. And this is only after 2 rotations.”


Rotating means moving groups of up to nine cattle around on once-acre test plots. The cattle spend two or three days on select plots each month throughout the summer. Martha Rosemeyer says researchers were interested in the breed of cattle because in Europe, they’re referred to as “eco-cows.” That’s because of their unique ability to eat plants that have inch-long thorns.


“They’ve got really tough tongues – they wrap them around these and pull – so they pull these things up like prickly ash leaves off and aren’t really bothered by thorns. They actually like thorns to rub and scratch…they’ll lean on things and scratch and they’ll break them and change the vegetation in that way too.”


Peter Rathbun says it didn’t take long for his cattle to tackle a patch of prickly ash after the gate into one test plot was opened.


“They ran over to it and started eating the actual bush. And I loved to see the reaction of some of the graduate students who’ve been working on this for a very long time. In their heart of hearts they really had some doubts whether the animals were really going to like to eat the junk.”


Once results are in by the summer of 2003, consultant Martha Rosemeyer says researchers may have a better idea of how effective the cattle will be at permanent eradication of unwanted plants.


“Certainly if you knock down a plant by taking off it’s above ground vegetation a number of times, it weakens the plant and it eventually will die. That’s what we’re hoping will happen but we’re not sure we need to test this and see the results…it’s speculation at this point.”


By comparison, Rosemeyer says on Department of Natural Resources land, a few test pilots were grazed and burned earlier this year to compare the weed control with the Highland cattle. It turned out that combination was too destructive and the burning was discontinued.


Meanwhile, not only do these animals eat through the bad stuff, but they also provide great hamburgers. Rathbun sells the meat as a low fat, very tasty source of protein.
