New research shows that Americans health would benefit dramatically if we ate less salt. But some people say it’s not the salt in the saltshaker that’s the problem. Julie Grant reports:

Darryl Bosshardt comes from a salt family. His grandfather started mining salt on their farm in central Utah. When Bosshardt hears about a new study that shows 100-thousand American lives could be saved each year if everyone reduced their salt intake by just a half teaspoon – he cringes.
He says salt is being given a bad name.

“And the challenge is, how we define salt.”

Most of the salt today all looks the same – perfectly pour-able, uniform bright white grains. It’s pure sodium and chloride, but Bosshardt, whose family owns the Real Salt Company, says it’s not the same as naturally occurring sea salt.

“Sea water occurs with many trace minerals. Over 50 to 60 trace minerals. It doesn’t occur, the salt in sea water doesn’t occur, as pure sodium and chloride.”

Bosshardt says those trace minerals help the body to process sodium, but most salt today looks perfect because the trace minerals have been taken out. He says when our bodies lack the minerals needed to process sodium; it raises blood pressure, which can lead to heart problems.

There are some books by holistic doctors that make these kinds of claims,but there’s not much science to prove this.

Most doctors today say salt is salt; sodium chloride. Our bodies need it, but not as much as much as most Americans are eating.

Dr. Kirsten Bibbins-Domingo is a professor of medicine and epidemiology at the University of California in San Francisco. She’s lead author of that new study on salt – the one that finds Americans could reduce deaths from heart disease by 100-thousand just by slightly reducing salt consumption:

“I don’t think we’re saying salt is bad and one of these other types of salt would be good. I think the newer types of salt that are on the market might have a lower sodium content for the taste that they have and so that would certainly be potentially beneficial.”

But Bibbins-Domingo says most Americans only get 6-percent of their sodium from their own saltshakers. The rest comes from processed foods and restaurants. So buying expensive sea salts with those trace minerals isn’t going to make much difference to most people. She says the problem is that salt is ubiquitous – people don’t even realize they’re eating it:

“If you start out with a healthy bowl of cereal with some milk, you’ve already consumed quite a bit of salt right there. If you have that healthy turkey sandwich or tuna sandwich, you have a bit of salt right there. If you have the marinara sauce with the pasta, you have salt there. So you realize that there are so many different ways, without you choosing items that we might clearly associate with a high sodium content, that there are a lot of places that we’re all consuming salt.”

Bibbins-Domingo supports efforts like the one in New York City. There Mayor Michael Bloomburg is urging food manufacturers to reduce the salt in their foods by 25% over the next five years.

Mark Kurlansky thinks it’s a terrible idea. He wrote a book called “Salt.” When laws curb smoking – that’s one thing. But salt is something different:

“You have to deal with the fact that people like salt. There isn’t the moral imperative of cigarettes because there isn’t a problem of second hand salt. If you don’t want to eat salt and the guy at the next table wants to eat it, it’s not going to affect you. It becomes an issue of government messing around with individual choice.”

But most people don’t realize they’re making that choice – there’s just so much salt in all the foods they buy. Other countries, such Finland and England, have worked with food manufacturers to lower salt content. In the UK, they cut sodium in foods by 10-percent. And researchers say the public didn’t even notice. They’re still studying to see if it’s actually improved health.

If you read nutrition labels on food packages, you might be surprised by how much sodium there is in a lot of foods.
Some researchers say all that salt is causing a plethora of health problems – and they want the government to force food manufacturers to lower the salt content. Julie Grant reports.

When Dr. Kirsten Bibbins-Domingo sees patients with high blood pressure, she advises them to cut back the on the salt.

She says they often return to the office – happy to announce that they’ve cut out fast food and processed snacks.

“AND THEN I ASK THEM TO TELL ME WHAT THEY’RE EATING AND I AM AWAYS BLOWN AWAY WHEN THEY COME BACK WITH THESE NICE HEALTHY VEGETABLE SOUPS THAT ARE CHOCKED FULL OF SALT. AND SO ALL THE THINGS THAT THEY DON’T REALIZE ARE HIGH IN SALT ARE ACTUALLY STILL THERE IN THEIR DIET.”

Bibbins Domingo is associate professor of medicine and epidemiology at the University of California in San Francisco. She’s also lead author of a recent study published in the New England Journal of Medicine.

Researchers at Stanford and Columbia University Medical Centers co-authored the study.

They did a computer simulation – to see what would happen if every American reduced their salt intake by a half teaspoon a day. That’s 3 grams.

“WHAT WE FOUND THAT IS IF WE WERE ABLE TO REDUCE SALT IN THE U-S DIET BY 3 GRAMS PER DAY, WE WOULD ANTICIPATE 100-THOUSAND FEWER DEATHS EACH YEAR, 100-THOUSAND FEWER HEART ATTACKS, AND MORE THAN 100-THOUSAND FEWER CASES OF NEW HEART DISEASE.”

Bibbins-Domingo says the health savings of reducing salt are comparable to cutting the number of smokers in half.

But not everybody puts that much stock in the new study.

Michael Alderman is a professor of medicine and epidemiology at the Albert Einstein College of Medicine. He says the government shouldn’t act so quickly based on this new study:

“WELL, IT’S INTERESTING THAT IT’S CALLED A STUDY, WHICH I THINK SORT OF SUGGESTS THAT THERE ARE REAL OUTCOMES AND REAL PEOPLE THAT WERE STUDIED. IN FACT, OF COURSE, WHAT IT IS A SIMULATION, A MATHEMATICAL MODELING.”

Alderman says there are lots of different findings when it comes to sodium consumption. And some show reducing salt intake could have actually have negative health effects:

“WE KNOW THAT REDUCING SODIUM INTAKE, BY AN AMOUNT SUFFICIENT TO REDUCE BLOOD PRESSURE, ALSO INCREASES SYMPATHETIC NERVE ACTIVITY, IT INCREASES RESISTANCE TO INSULIN…”

If we already ate low salt diets, the researchers in this latest salt study say those concerns might be valid. But Dr. Bibbins-Domingo says salt consumption in the U.S. is higher than is recommended, and it’s on the rise.

But she says there are high levels of salt in so many foods, it’s hard to avoid. Cereal. Bread. Lunch meat. Pasta Sauce.

And she says consumers can’t really reduce salt consumption without some changes by food manufacturers.

“RIGHT NOW THERE ARE NO CHOICES THAT ARE REALLY AVAILABLE THAT MIGHT BE LOWER IN SALT. I THINK THAT’S WHERE THE EFFORTS WITH THE FOOD MANUFACTURERS ARE ABOUT REALLY MAKING A RANGE OF CHOICES SO WE CAN EAT LOWER SALT, WHICH IS VIRTUALLY IMPOSSIBLE RIGHT NOW.”

Some governments are responding. New York City has already started urging food manufacturers and restaurant chains to lower the salt in their foods by 25-percent over the next five years. Bibbins-Domingo says California is considering salt limits in foods the state buys for schools, prisons and other public institutions.

She also wants the Food and Drug Administration to require food makers to alert consumers when foods are high in salt.

In the meantime, Bibbins-Domingo advises her patients to look at food labels – and really look at the sodium content – so they know what they’re getting.

Every year, more than one million
Americans have a heart attack.
The majority survive, thanks

on a program that’s shifting
its focus from miraculous cures
to persuasion – getting the family
of patients with heart disease
to change the ways they live:

(sound of aerobics class)

It’s a frigid January night in Ottawa, Canada. Most people are curled up on the couch. Debbie Joy is doing push-ups, lifting weights, even hula-hooping.

“After long day – I get up at 5:30, I get to the office at 7:30, I don’t leave there until 4:30, quarter to five. It takes a lot for me to go out and exercise. You just have to be motivated and do it.”

A couple of years ago, Joy didn’t have that motivation. But she did worry.
Both of her parents had died young of heart disease and, in the back of her mind, she knew what she should be doing to take care of herself.

Then she saw an article about a study at the University of Ottawa Heart Institute for the family members of current and former patients.
Bob Reid is directing the study.

He says research has found that family members of patients have a 30 percent chance of contracting heart disease themselves within 10 years.
But there’s been very little focus on this group.
Reid says he and his colleagues realized that if they wanted to focus on prevention, they had a major high-risk group already coming through the door.

“I think anybody who’s practiced in a hospital for any length of time recognizes that sometimes our patients of tomorrow are the family members of our patients today. Families tend to have very similar smoking habits, very similar eating habits, very similar activity habits. This really is a group that can benefit from fairly close attention.”

Close attention is the key to the heart institute’s program.
Family members work with a dietician, a nurse, and personal trainers to set up a new lifestyle. Then, they keep working with them.
Participants keep close track of exercise and their diet. The professionals track blood lipids, weight, and cholesterol levels.

Debbie Joy says it worked.

“The fact that you were watched, you were called every week, it made you follow the program. Then they got you into a routine. So they called you every week for 6 months, then it was dropped to once a month. At that point, you were in a routine and it was easier to follow.”


After three months, Joy’s weight and cholesterol levels dropped – and stayed there. One year later, she’s still exercising four days a week and eating well. It’s a part of her life now – she’s made friends at the gym and her family has adjusted to her new cooking methods.

The ultimate goal for the heart institute is to demonstrate that this works, and to justify funding the family prevention programs full-time.

The ultimate goal for Debbie Joy is quite simply, to live longer.

“You know, I have two kids and I want to be around for my grandchildren. So, it’s never too late.”

Trying for a Healthier Holiday

With so many Americans facing diabetes,
heart disease, and other health problems,
the Thanksgiving meal has become a battleground
in some families. Some family members want
to make it a healthy meal, others want to
stick with their traditional family dishes.
Julie Grant reports:

Four years ago, Linda Barberic gave her left kidney to her sister. The surgery went well. But since then, there have been a lot of other health problems in the family.

“We’ve had a few strokes in the family, we’ve got diabetes, we’ve got high blood pressure, we’ve got some other heart conditions, a few heart attacks.”

That’s some serious stuff. Linda thinks a lot of it has to do with the way her family eats: lots of salt, fat and sweets. She is hosting everyone for Thanksgiving dinner. And thought this might be a good time to get them all on board with healthier eating.

So she sent out a mass email to the family.

“So I thought this year, why not give everyone a challenge and make it a healthy Thanksgiving. Really – no fats, no butters, no salts, no heavy creams.”

Linda even suggested some recipes: steamed green beans with lemon zest, fingerling potatoes roasted with fresh garlic and thyme.

The resounding response: No salt, no fat, no fun.

Someone even said they wouldn’t come. They wanted the turkey with gravy, green bean casserole with crispy onions on top, and Mom’s dumplings with lots of butter.

Her brother-in-law Matt Previte is one of those with a heart condition. He and Linda’s sister, Sandy Previte, appreciate Linda’s thought, but…

Matt: “For one meal, for one day, one special occasion – it’s not worth it.”

Sandy: “How often do we eat gravy? Twice a year. So I’m like, let’s do the traditional. Why not? Let’s just stick with what it’s about – people getting together to have good food.”

So Sandy says why not have the gravy, have the butter?
But her sister Linda says it’s not one or two days a year. Her family, like many, eats fatty, salty foods all the time.
That’s one big reason why two-thirds of American adults are considered overweight or obese. And diabetes has become an epidemic.

So, why do we keep going back for more – when we know it’s making us sick?
Linda Spurlock is director of human health at the Museum of Natural History in Cleveland.
She says we’re hard-wired to crave sugar, fat and salt.

“If you did not have the inherited yearning for fat or for sugar and grab it anytime you could get your hands on it, you probably would not live to reproduce back 2- or 3- million years ago.”

But while our ancestors had to smash open bones to get to the marrow – so they could get the fat they needed – we can just pull up to the drive through and order whatever we want to eat.

Spurlock says the original Thanksgiving meal was probably a small, lean turkey, squirrel, raccoon, and roasted root vegetables.

“And how it got bigger and bigger and bigger –
I have a feeling that it wasn’t until quite recently that people had the expectation of several kinds of pie for dessert and yes giblet gravy and mashed potatoes and sweet potatoes.”

Spurlock says Americans can start eating healthier by training themselves to enjoy the simple taste of vegetables. But she says Thanksgiving probably isn’t the time for it.

Linda Barberic has come to the same conclusion.

“ I kind of just backed off on it. And said, ‘do what you’re going to do.’ Thanksgiving is about family. I’m grateful that everyone is healthy this year and everyone is here. So, I’m just grateful to have Thanksgiving. But, I have a feeling there will be some fat. (laughs)”

Many of us have engineered physical activity out of our lives. We sit in front of the computer, we sit and drive everywhere. We don’t move much.

That’s what Steven Blair says. Blair is a professor of Public Health at the University of South Carolina. And he says, more than anything else, America’s physical in-activity will cause this century’s biggest public health problems.

“You want to stay out of the nursing home, the best insurance you can take out is regular physical activity program – three ten minute walks five days week. I’m not talking about training for the Ironman triathlon or a marathon.”

Good Fish, Bad Fish

  • Some grocery stores are training their staff on the benefits and risks of eating some kinds of fish. Nels Carson (pictured) answers customers' concerns about fish contamination. (Photo by Lester Graham)

Fish advisories are confusing. Their guidelines change depending on your gender and age,
and on the type of fish you’re eating. Reporter Kyle Norris boils down
some of the information in advisories and comes up with a few things to think about
when you eat fish:


So I did a little informal survey the other day where I asked my friends what they knew about
eating fish. Some of my friends said, “Hey, isn’t eating fish good for you?” Well, turns out they’re right. Fish are
great sources of protein. They’re low in “bad” fats and high in “good” fats, or omega-3
fatty acids, which help your heart stay healthy.


And some of my other friends knew that fish were bad for you. Turns out they’re also right. Fish
take in pollutants through their food and water. Toxins such as mercury, PCBs, and
dioxins. If humans eat enough contaminated fish, those contaminants can build up in our
bodies and cause serious health problems. Contaminants are especially threatening for
small children and women of childbearing age because they can affect children’s
developing nervous systems.


Governments put out advisories so we know which fish are safe to eat. But advisories aren’t
the easiest thing to understand. And anyway, what do you do if you’re in a restaurant, or
cruising through the grocery store and you just want some fish?


“Uh we’re standing in front of the seafood counter at Whole Foods and we’re looking at
our fresh case…”


That’s Nels Carlson. He heads up the seafood department at my local Whole Foods
Market. He says people ask him about fish safety everyday:


“It can be kind of a daunting topic, I think, because there is such a variety. It’s not just a
gross generalization. So it really, it takes a lot of dialogue between customers and team
members and having a very knowledgeable team member base here really helps that.”


They’ll ask him about mercury in the fish, a highly toxic metal that occurs naturally but is a lot more prevalent
mostly because of coal burning power plants. Mercury shows up in higher concentrations
in certain kinds of fish. It’s nice to have a knowledgeable guy like Nels to talk with. Good fish vendors, such as
Whole Foods, go through special training on fish safety. But what if there’s no seafood
expert hanging out next to the fish sticks in the freezer section, if you know what I mean?


Anita Sandretto teaches in the Environmental Health Sciences department at the
University of Michigan’s School of Public Health, and she said that my friends are right.
Okay, well, she didn’t really say that, but she said there are good things about fish and there are bad things about fish:


“If you want to have the benefit of the fat and the omega-3 fatty acids, eat fish with more
fat, but the fat will also be where you will see the contaminants such as PCBs, dioxin.
The flesh will also be where you might have the mercury contamination.”


See, that’s the thing about eating fish: it gets complicated and there are no hard and fast
rules. Sandretto says eating fish is all about treading a line between the advantages and
the risks. So, if there is a risk, you want to reduce it as much as possible:


“…Because if you have any risk in a particular type of food, if you only consume once in
while, you have a less risk of anything bad happening.”


So think in terms of moderation and variety. Sandretto says it’s cool if you want to eat fish once or
twice a week, and to try and vary the kinds of fish that you eat. She says moderation and
variety are actually great rules of thumb to apply to your entire diet. So you could eat a
turkey sandwich on white one day, tuna on whole wheat the next, and a veggie burger the day
after that.


If you eat fish caught from local waters, check with your regional or state health
departments for their fish advisories. Just because a waterway looks clean or is in a
picturesque setting does not mean that its fish are harmless. Contaminants enter the
water in all kinds of ways.


One last thought: imagine a little fish with a little bit of contamination in its body.
Now imagine a medium-sized fish, who swims along and eats that fish and 99 of its closest small
fish friends. That medium guy now has 100 times more contamination than the small fish.
And now let’s say a big fish swims up and gulps down ten medium fish. That big fish has a
concentration that’s 1000 times higher than what that origianal small fish had.


So the moral of that story is, eat smaller fish when possible, also called pan fish. And
at the end of the day, keep in mind that the majority of research, including a recent study
from Harvard’s School of Public Health, say that the benefits of eating fish in moderation
outweigh the risks.

A lot of studies have linked air pollution with heart and lung
problems. A new study suggests your diet can worsen air pollution’s
effects on you. The Great Lakes Radio Consortium’s Michael Leland
has more:


Every time you inhale, you’re breathing in tiny particles from dust, soot
and smoke. They can increase both the plaque buildup in your arteries,
and the risk of a heart attack or stroke.


Now, a study led by Dr. Lung Chi Chen at New York University’s
School of Medicine says a high fat diet combined with bad air led to a
faster buildup of plaque in the arteries of mice. He says that’s because
air pollution affects lipids – fats – in the blood. It changes their
characteristics, or oxidizes them, which leads to more plaque on artery
walls.


“If the mice are fed with high-fat, then the level of the oxidized
lipid will be higher, because they have more lipid in their blood.”


Dr. Chen says arteries of mice on a high-fat diet and breathing dirty air
were 42-percent blocked. Mice breathing clean air had arteries that were
26-percent blocked.


He hopes the study not only encourages people to eat better, but also
persuades the government to toughen air quality standards.

Returning Quality Food to Urban Areas

Finding a big supermarket is next to impossible in many inner-city
neighborhoods. That means a lot of people do their shopping at convenience
and liquor stores, where there’s rarely fresh produce. The Great Lakes
Radio Consortium’s Sarah Hulett reports on one group’s efforts to get around
the grocery store problem – and help revitalize a neighborhood:

Finding a big supermarket is next to impossible in many inner-city neighborhoods. That means a lot of people do their shopping at convenience and liquor stores, where there’s rarely fresh produce. The Great Lakes Radio Consortium’s Sarah Hulett reports on one group’s efforts to get around the grocery store problem and help revitalize a neighborhood:


(Sound of traffic)


Up and down this street as far as the eye can see are crumbling and burned-out buildings. This used to be a thriving business district. It’s where Vlasic Pickle, White Owl Cigar, and Lay’s Potato Chips grew into national brands. Today, the most evident sign of commerce is the prostitutes walking the street. Smack in the middle of this is Peacemaker’s International. It’s a storefront church where Ralph King is a member.


“Now if you look at it you see that there’s no commercial activity, no grocery stores within a mile of here. And our concern was that people had to eat.”


There are about seven liquor stores for every grocery store here on the east side of Detroit. Some people can drive to the well-stocked supermarkets in the suburbs, but many families don’t have cars, and King says the city busses are spotty.


“So they’re buying food at convenience stores or gas stations. And quite frankly, it just doesn’t seem a good fit that a community has to live off gas station food.”


That means processed, high-starch, high-fat diets that lead to illnesses like heart disease, diabetes, and high blood pressure. Those are all problems that disproportionately hit African Americans, and public health researchers say those higher rates of illnesses are linked to the food availability problems in poor black communities.


Amy Schulz is with the University of Michigan, and she’s studied the lack of grocery stores in high-poverty neighborhoods.


“What we found, in addition to the economic dimension was that Detroit, neighborhoods like the east side that are disproportionately African American are doubly disadvantaged in a sense. Residents in those communities have to drive longer, farther distances to access a grocery store than residents of a comparable economic community with a more diverse racial composition.”


In other words, if you’re poor and white, you have a better chance of living near a grocery store than if you’re poor and black. Ralph King and the folks in this neighborhood want to get around that problem. So about three years ago, they decided to try and reopen a nearby farmer’s market. They turned to Michigan State University Extension for help. Mike Score is an extension agent.


“I thought it would just be the process of organizing some people, helping them buy some produce wholesale, setting up in the neighborhood, selling the food, and generating a net income that could be reinvested. And I was really wrong.”


The farmer’s market was a flop. Score says produce vendors set up in the neighborhood, but the fruits and vegetables sat all day, unsold. He says the problem was they were using the wrong currency. Most people in this neighborhood have very little cash on hand, and they need to use their food stamp cards to shop for groceries.


So, Score helped develop a plan for a neighborhood buyers’ club that can negotiate low prices by ordering in bulk. His business plan also calls for job training for people in the neighborhood.


“It’s going to give people who are chronically unemployed but who have some entrepreneurial skills access to food at a lower cost, and that enables them to think about starting restaurant businesses or smaller retail businesses. So that’s an important part of this project: in addition to getting people groceries, it also creates some job opportunities.”


It’s been a struggle to get the program off the ground. It took a long time to get approval from the U.S. Department of Agriculture for a machine to read peoples’ food stamp cards. People have stolen some of the project’s meager resources, but Mike Score and Ralph King say they’ll stick with it until families in this neighborhood can put decent food on their tables. And they say they hope it can be a model that other low-income communities around the country can use.

Two Plans to Reduce Soot

Federal regulators are looking at two plans for reducing the
amount of soot in the air. As the Great Lakes Radio Consortium’s Sarah
Hulett reports, public health advocates say tougher regulations would
prevent thousands of premature deaths from heart and lung disease.


One of the plans would cut the amount of pollution in a 24-hour period by more than half. A second plan would allow a little more soot each day, but it would cut the total amount allowed each year. EPA Administrator Stephen Johnson is expected to make a make a choice between the two plans by the end of the year.


EPA researchers looked at the links between air pollution and premature death in nine U.S. cities. Janice Nolen is the director of national policy for the American Lung Association.


“In those nine cities they were estimating that each year, about five thousand people died of particle pollution, where the standards are right now.”


Nolen says the standards EPA is considering would greatly reduce those deaths. The new standards would take effect in the fall of 2006.

Creating Particle Pollution Warning System

In the summer, local weather forecasts often
include information about dangerous ozone levels.
But scientists are learning more and more about
another type of pollution that can reach harmful
levels even in the winter months. And as the Great
Lakes Radio Consortium’s Sarah Hulett reports… we
might be hearing more about this type of pollution in
our daily weather reports:

Transcript

In the summer, local weather forecasts often include information about dangerous ozone levels. But scientists are learning more and more about another type of pollution that can reach harmful levels even in the winter months. And as the Great Lakes Radio Consortium’s Sarah Hulett reports, we might be hearing more about this type of pollution in our daily weather reports:


Parts of the region recently reached “code red” for poor air quality. And
that had some people perplexed. Warnings about dangerous levels of ozone are
frequent on hot summer days, especially in urban areas. But this was the
middle of winter.


The warnings were for high levels of tiny particles that federal regulators
only recently began monitoring. They’re spewn from diesel engines,
factories, power plants, and fireplaces. Air monitors in Michigan,
Minnesota, Pennsylvania, and Indiana recently registered unhealthy levels of
these particles – some of them for a few days straight.


Jim Haywood says the problem was an unusual weather event for this time of
year. Haywood is a meteorologist with the Michigan Department of
Environmental Quality. He says a high pressure system moved very slowly over
the Great Lakes region for several days. When you get high pressure, the air
below sinks, generating a layer of warm air that acts like a lid.


“So that warm air that was sinking effectively stops at a few hundred feet
from the surface of the ground. It acts like a cap. It does not let any of
the pollutants that are released at the surface pop up through that cap.”


So all the pollutants that would have gotten picked up and diluted by the
wind instead just hung out for days – building up, and reflecting sunlight
to create haze.


Eventually, a cold front pushed the high pressure system out of the way, and
took the pollution with it. But what about those few days when the Environmental Protection Agency was warning about unhealthy levels of particulate pollution? For people with
heart or lung disease, agency health officials say short-term episodes can
lead to asthma attacks or even heart attacks. And they say healthy children
and adults can experience throat and lung irritation.


Susan Stone is an environmental health scientist with EPA. She says
particle pollution warnings could soon become a staple of the daily weather
report – much like the familiar summer ozone warnings.


“With ozone, we have the network in place to be able to deliver those
forcasts, people are used to hearing that on TV, and we are working to
provide that same level of coverage for particle pollution.”


Stone says EPA is rolling out a new program called Enviro-Flash
nationwide. It sends real-time air quality information to people’s email
accounts or pagers. EPA is offering the service through state
environmental agencies. And beginning in 2010, areas that register
unacceptable levels of particle pollution will be required to clean up their
air.
