You might think you know corn –
as in corn tortillas, corn-flakes,
corn-bread and so on. But do you
really know corn? Like, did you
know that our last harvest could
be one of our biggest, or that most
American corn is genetically modified?
Shawn Allee reports experts
want us to get re-acquainted with
our biggest crop because we need
to make huge decisions about its
future:

Virginia Walbot researches corn genetics at Stanford University, and recently she got news that didn’t just make her day – it kinda made her decade. Walbot says scientists just finished sequencing genes of an important corn genome.

“The genes are like the words in different languages and what you need is a dictionary that lists all those words, and that dictionary for us, is the genome sequence.“

Walbot says this research could allow us to breed new corn varieties faster than ever before. That’s a big deal because even though we benefit from corn we have now, we could make it better. For example, corn creates environmental problems – take corn fertilizer.

“Of course, adding fertilizer really boosts a lot of yield, but the downstream effects aren’t really great. So, there’s runoff from farms that contaminates the water supply. Making corn as efficient as possible and just giving enough fertilizer to sustain yields, those would be fantastic goals.“

Now, most corn researchers want to meet environmental goals, but there’s a question science alone can’t answer – what kinds of corn should we grow or improve?

Kinds of corn? Maybe you’re thinkin’ “corn chips” versus “popcorn” but there’re bigger differences. We eat sweet corn – most corn’s starchy industrial stuff.

“I think that’s one thing consumers get confused about. Today, only one percent of corn production goes into sweet corn.“

That’s Pam Johnson. She’s with the National Corn Growers Association. Johnson says about half our corn goes to animal feed, then we eat the meat or dairy products from that.

But a lot goes to industrial products, too. Ethanol uses more than a third of the corn in the American corn market.

Johnson says corn farmers want scientists to create specialty industrial corn that can fetch premium prices – like corn just for ethanol or corn just for renewable, corn-based plastic.

“You know, we’ve always said for a long time that anything that’s made from petroleum might be able to be made from a renewable and I think that’s an exciting thing to ponder as a corn grower.“

Johnson predicts new genetic science will also improve corn we eat directly, but is that likely to happen?

“I have my doubts.“

That’s Rainer Bussman. He’s with The Missouri Botanical Garden, and he studies how people use plants.

“Feeding people is less economic incentive than producing large amounts of corn for animal feed or biofuels, so I do have my doubts there.“

Bussman says it’s a shame food varieties of corn will get less attention from genetic research. He says he worries about food security. He figures if we grow more types of food corn we’ll be better protected from crop diseases.

It’s also a matter of taste, though. Bussman’s traveled the world and tasted corn we don’t grow here – like a blue kind in South America.

“They would call that maize murada which means purple corn and that is mostly used to produce a very refreshing, sweet beverage, so you get this get this deeply purple, sugary drink. It’s all natural, no sugar added.“

Bussman says Native Americans and the earliest settlers produced hundreds of varieties of corn for all kinds of food dishes – corn for just pudding, just bread, just porridge, and so on. They created this food diversity without modern genetic science, but we do have it.

Bussman asks why should our science just improve animal feed, ethanol, and bio-plastic? Why not make food our priority, too?

Counting calories is easier
to do now that more restaurants
are publicly posting calorie
information about their food.
But Samara Freemark
tells us why those numbers might
be misleading:

18% – a new study says that’s the average amount that restaurants underreport the calories in their dishes.

Researchers at Tufts University analyzed the calorie content of meals from chain restaurants. Then they compared those numbers to the calorie counts posted publicly by restaurants on websites and menus.

Susan Roberts is the senior author of the study. She says in some cases, dishes had twice as many calories as they were supposed to.

“You just assume that the numbers are right, you don’t really think about, well, is this number only half what it really is? To have the calories on the web or in the restaurant, that would be a great thing. But they do have to be accurate.”

Roberts says the biggest culprit is portion size – restaurants serve larger amounts of food than advertised. She says the researchers also found that many restaurants served extra side dishes that weren’t included in posted calorie counts.

Proposed legislation would put
in place the most sweeping
regulations yet on ocean
aquaculture – or offshore fish
farming. Samara Freemark tells us why people
think regulations matter:

Critics of aquaculture say the practice can spread disease, introduce invasive species, and pollute the environment.
The Ocean Conservancy’s George Leonard says that’s a problem.

“In the absence of an overarching framework, aquaculture continues to move forward kind of in fits and starts here in the US. And we think if it proceeds that way, many of the environmental concerns will kind of fall through the cracks.”

Legislation introduced last week in Congress could change that. The bill would require fish farmers to apply for federal permits before setting up shop. Those permits would set standards to protect ocean ecosystems.

The bill would also provide money to research how aquaculture is impacting the environment.

Santa’s reindeer are not doing
so well. Rebecca Williams reports
one group wants to get them on
the endangered species list:

Caribou, also known as reindeer, are declining all over the globe. The group International Fund for Animal Welfare says two subspecies of caribou are in especially bad shape.

Nathan Herschler is with the group. He says these caribou live in the Arctic. And climate change is making their lives miserable.

“Instead of soft snow that’s falling on the ground, we’re getting freezing rain. That’s encasing the land in ice and the caribou are literally starving to death.”

Herschler’s group wants the US government to put the caribou on the endangered species list. Even though the caribou live in Canada, he says the listing would help by banning the import of caribou or caribou meat into the US.

The soda-pop you drink, the
t-shirt you wear, the cooking
oil you use – all might contain
genetically engineered material.
Lester Graham reports on a
continuing trend in agriculture:

The U.S. Department of Agriculture reports, this past year, 88% of cotton, 91% of soybeans and 85% of the corn crops planted were genetically altered.

That means corn syrup, cotton cloth, and hydrogenated soybean oil are all more than likely are from genetically engineered crops.

Margaret Mellon is with the Union of Concerned Scientists. She says farmers might embrace them, but genetically engineered crops have not really advanced American agriculture that much.

“I’m not saying there are not benefits, but they’re really modest. In particular, I think it’s important to note that it really hasn’t had an impact on yield – which is what we need if we’re going to increase the amount of food in the world and feed more people.”

The makers of genetically engineered seeds, companies such as Monsanto, say their crops do increase yields by stopping weeds and insect damage. The big bio-tech companies say their crops save farmers money, mean fewer harmful pesticides and reduce soil erosion.

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.

When we hear about kids and obesity,
a lot of people point the finger at
schools. Most kids today eat about
half their meals at school, and many
cafeterias are filled with junk food.
In the second half of our school lunch
series, Julie Grant reports that some
districts are trying to improve what
they serve – but there are a lot of
challenges:

(sound of a school cafeteria)

The food available in school in Shaker Heights, Ohio looked a lot different a few years ago. They used to sell lots of pop and French fries. Today, we’re standing at what’s called the Nutri-Bar. Students can buy salads, sandwiches, even sushi.

“Fresh, healthy and portable. That’s the motto of the Nutri-Bar. This has been a big hit with our students.”

Peggy Caldwell is spokesperson for the school district. She says a group of parents started worrying about national obesity and diabetes rates among children and pushed for the change.

“They want us to provide healthy choices. They want us to provide nutritious meals. They understand that students learn best if they are healthy and well fed.”

Parents worked with the district to improve the food available in the schools.

(school bell)

“And, here they come.”

It’s lunchtime. Students are packing into the cafeteria.

(sound of a blender)

A few girls order fruit smoothies at the snack bar.

(sound of students in line)

But the line is much longer for the hot meals. Cheeseburgers and pizza are always on the menu. Today’s special: chicken strips and mashed potatoes. That might sound like a lot of fat and salt, but Caldwell says it’s actually pretty healthy.

“The chicken strips are baked now, they’re not fried. The potatoes are baked or, if they’re mashed potatoes, they’re made with low fat milk. There’s less sodium. They may look the same, but they’re better for you than they used to be.”

Caldwell says they’re starting to make pizza with whole wheat crust and the pasta is all whole grain.

But serving healthier food has cost the district. They had to buy ovens so they could bake. They have to pay more for labor to chop vegetables and make smoothies. And the food, itself, costs more. Fruits and vegetables come at a higher price than those processed foods that are high in sugar, fat and salt.

Especially in schools. Schools can actually get 15% to 20% of their food for free through the U.S. Department of Agriculture.

Janey Thornton is undersecretary for food and nutrition at the USDA. She says when farmers have too much of, say, blueberries or green beans or ham, the USDA buys those commodities for schools.

“If we have an abundance of blueberries – in order to stabilize the market, to keep prices near where they should be, then those products are purchased by the federal government.”

Then the government offers those blueberries for free to schools. That sounds might sound like a win-win – helping farmers and schools. But lots of times those berries are processed into unhealthy things – like glazed blueberry snack pies – before they get to schools.

Peggy Caldwell says the government food presents a challenge. Schools can’t afford to turn down free food. But it’s often high in salt and fat, and at odds with her district’s efforts to provide healthy lunches.

“It’s not always consistent with the nutritional guidelines. It can be a challenge for a staff to use in a way and in quantities that really meet the health requirements we’re trying to meet for our students.”

Some critics have gone so far as to call the schools garbage disposals for un-sellable farm commodities. Janey Thornton with the USDA scoffs at that suggestion.

“I would love to have that garbage disposal in my home, in my freezer if that were the case.”

Thornton worked 25 years in school nutrition at a local district before coming to the USDA. She says the ground meat has gotten leaner, the canned fruit is now healthfully packed in a very light syrup.

(sound of a cafeteria)

For those that disagree, debating the federal government might seem like a huge undertaking. But there maybe even tougher tasks for schools encouraging healthful eating, like Shaker Heights.

Grant: “What are you having for lunch?”

Student: “Ice cream. Chocolate. Soft serve. It’s really good.”

Part 1: School Lunches and Super Doughnuts

We hear a lot about American kids
and obesity. Many children eat half
their meals at school – and some
parents question whether those meals
are teaching kids healthy eating habits.
In the first part of our series on
school lunch programs, Julie Grant
reports on the push for change in
the cafeteria:

Gwen Rosenburg was appalled when she saw the menu at her son’s elementary school. It was called a heart-healthy menu.

“So, I saw chicken patties and corn dogs and chicken nuggets, hot dogs and hamburgers. And super-donuts for breakfast and s’mores flavored Pop Tarts for breakfast. And then I got really angry – because I don’t like to be called stupid.”

Super-Donuts. That sounded like junk food – not heart healthy food. So Rosenburg called the school district to complain.

But her district, like many, hires an outside company to take care of food service. So Rosenburg started writing to the company, Aramark, to find out the nutritional content of the foods it was serving. She didn’t get many answers.

Rosenburg didn’t want her kids to eat the school food.
Most people told her to stop complaining and just pack lunch.

But that only helped her to realize why this bothered her so much. Lots of families don’t have enough money to pack lunch – so their kids have no choice but to eat the subsidized school meals.

“It bothered me that my tax dollars were paying for food that I wouldn’t serve my kids. Once I made that realization it seemed suddenly unethical for me to do nothing and say, ‘thank God I’m not poor.’”

Rosenburg went on a campaign and contacted everyone she could think of about it. She also started her own blog to document her attempts to improve school meals in her district.

Patrick McMullen is in charge of food service in Rosenburg’s district. He works for the company, Aramark. McMullen says things are a lot better now than they were ten years ago. Back then, the high school had soda on tap, free with lunches.

Today, you can’t even buy carbonated beverages in the schools here. McMullen says most people agree that was a healthy change.

But it’s not usually that clear: he says every family has its own idea of what is good food.

“Somebody likes chicken nuggets, somebody doesn’t. A lot of people see chicken nuggets as an unhealthy item. Some people think it’s perfectly fine because it’s a lean meat.”

McMullen says it’s his job to make sure the school meals stay within the district’s budget, while meeting USDA nutritional guidelines. And that kids buy and eat them. That’s why things like that Super-Donut exist.

“A Super-Donut is a fortified donut that’s made with juice and it’s infused with nutrients.”

McMullen says some parents see Super-Donuts as a healthy item. But lots of parents around the country have complained about the Super-Donut.

Janey Thornton is Undersecretary for Food and Nutrition at the US Department of Agriculture. The USDA is in charge of the national school lunch program.

Thornton says a food like the Super-donut is handy. Kids like it and they can eat it at their desks. She says parents wouldn’t complain if it was shaped like a piece of breakfast bread.

“Because it’s round with a hole in it, and we assume that it has donut-like qualities then, it sometimes gets a bad rap.”

But some parents think it’s giving kids a false impression of what’s healthy. Gwen Rosenburg says the Super-Donut is a prime example of how school meals are setting up kids for a lifetime of bad eating habits.

“Alright, I’m not supposed to eat a donut for breakfast. Sometimes I do, right. But I don’t believe that it is healthy. I know that it is not a healthy food option. But when you present it to children and say this is what the government, taxpayers, this is what your community has purchased for you to eat and you get it for free. It’s a donut. What exactly are you teaching them to do for the rest of their lives?”

Rosenburg says there are so many efforts to teach kids healthy habits, but those messages are easily undermined in the cafeteria.

There are districts around the country that have been improving school meals – offering salad bars and whole grain breads. Rosenburg says all her efforts have made some difference. Her district has added foods she thinks are healthier to the menu, and her son even buys his lunch sometimes.

“All I really wanted all along was something that I could say ‘I would let my kid eat that.’ And if I would let my kid eat that, then I would gladly whatever tax dollars to give it for free to the kid whose family can’t afford it. But if they’re going to serve food that I won’t let my child eat, I do not want them to serve that to impoverished children. It’s morally wrong. And it reeked to me like a form a classism.”

Americans’ waistlines have been
expanding for decades. But new
research suggests at the same time,
more and more food is going to waste.
Shawn Allee reports:

On average, Americans weigh 20 pounds more than they did back in 1974.

But Kevin Hall found there’s more to the story. He studies nutrition at the National Institute of Diabetes and Digestive and Kidney Diseases.

Hall’s research revealed we produce more food to keep up with our bigger appetites, but he also found we’re wasting more.

“We were kinda shocked to see that the rate of increase of food supply was greater than the rate of increase of food consumption we calculated. Somewhere along the supply chain from the farm to the dinner table, that food was wasted.”

Kevin Hall estimates well more than one third of our food production goes to waste.

He says it’s not clear who’s to blame, but someone should find out because food production uses a lot of water and fuel.

Africanized Honeybees – also known
as killer bees – are moving farther
north. The hybridized bees escaped
from a lab in Brazil in the 1950s.
Mark Brush reports:

These bees have established themselves in a number of states throughout the southern U.S. They spread naturally and they are spread through trade. The bees can hide out in shipping containers. One swarm was found inside the engine compartment of a new car.

Now, despite the nick name “killer bee” – experts say, yes they’ll defend their nest with more gusto – but the killer bee name is just hype.

Gloria DeGrandi-Hoffman is a bee expert with the USDA. She says it’s likely that the bees will keep spreading – but beekeeping is an important line of defense against Africanized honeybees.

“You know, beekeepers, whether they’re small or large, are really the buffer between African bees and the public, because they keep pure European bees.”

DeGrandi-Hoffman says – Africanized or not – bees are still a critical part of our food system because they pollinate so many of our food crops.
