Sedentary work and obesity: another view

On May 26, the New York Times published a report of a new study on causes of obesity.  The study examined changing rates of physical activity in the workplace. Its conclusion?  Sedentary work is a major cause of rising rates of obesity in the United States.

The shift translates to an average decline of 120 to 140 calories a day in physical activity, closely matching the nation’s steady weight gain over the past five decades, according to the report.

Eric Schlosser and I wrote a letter to the editor pointing out a few flaws in that argument.  The Times did not publish our letter, but here it is:

To the editor:

It makes sense that sedentary work is a factor in the current obesity epidemic (May 26). But it cannot be an important cause. The changing American workplace cannot explain why the obesity rate among the nation’s preschoolers has doubled in recent years and that among elementary schoolchildren has tripled.

The rise in obesity worldwide is linked to the embrace of the American diet, not to a decline in manufacturing.

In China, childhood obesity has increased at least five-fold since 1985.

Simplest explanations are usually best. Reversing obesity means eating less and making healthier food choices.

It also means making it easier to do that by setting policies that promote smaller portions, lower prices on fruits and vegetables, restrictions on marketing food to children, and healthier school meals.

Of course, an increase in well-paid manufacturing jobs would help too.

The German E. coli outbreak: now it’s sprouts?

I haven’t said anything about the E. coli 0104 crisis in Germany up to now because I’ve been waiting for the evidence.  Without evidence, the source of the outbreak remains uncertain.

Yesterday, the German minister of agriculture announced that sprouts are the cause.  But are they?

What  is known without question is that the outbreak is deadly serious.  Bill Marler reports these shocking numbers as of June 5:

Deaths = 22 (21 in Germany, 1 in Sweden)

Illnesses = 2,243 (2,153 in Germany, and 90 more in 10 other European nations and the U.S.)

Cases of Hemolytic Uremia Syndrome (HUS) = 627

Why shocking?  This is a devastating disease, excruciatingly painful, with a high probability of causing lifelong complications.  And the disease is almost entirely preventable by following standard food safety procedures.

The idea that the cause is sprouts, and German sprouts at that, comes as a surprise.  Why?  First, sprouts are a frequent cause of foodborne illness and should have been high on the list of suspected foods.  Second, sprouts did not turn up in the case-control studies.

Instead, investigators examined cucumbers, lettuce, and tomatoes (and, in the process, put Spanish cucumber producers out of business).  As Marler explains, the German authorities didn’t want to take a chance, given the results of their investigation.

The case-control investigation was conducted by the Robert Koch Institute, the German equivalent of our CDC.

  • The cases: From May 29 to June 2, investigators interviewed 46 affected patients from Bremen, Hamburg and Lübeck about the foods they had eaten.
  • The controls: They interviewed 2,100 people who were not sick but were of similar age group, sex and region of residence.
  • The results:

Food Reported Eaten         % By Cases     % By Controls

Lettuce                                        84                           47

Cucumbers                                 75                           50

Tomatoes                                   80                            63

95% of the Cases had eaten at least one of the three vegetables.

This evidence strongly implicates these vegetables.  But did they not look for sprouts?

In another related study of people from a Frankfurt business company who had become ill, those who had eaten from the salad bar in the company cafeteria had a 7-fold increased risk of developing bloody diarrhea than those who had not.  No such association was seen for other foods investigated, such as dessert, fruit and asparagus.  Sprouts are not mentioned.  How come?

In trying to figure out what’s going on here, a BBC World News report raises even more questions (my emphasis):

The agriculture minister for Lower Saxony, Gert Lindemann, said there was a clear trail of evidence pointing to a plant nursery south of Hamburg [as the source of the contaminated sprouts].

The nursery has been closed, though officials say the outbreak’s source cannot yet be definitively confirmed.

…Mr Lindemann said epidemiological studies all seemed to point to the plant nursery in Uelzen in the state of Lower Saxony, about 100km (62m) south of Hamburg – though official tests had not yet shown the presence of the bacteria there.

“Further evidence has emerged which points to a plant nursery in Uelzen as the source of the EHEC cases, or at least one of the sources,” he said.  [What evidence?]

…Gert Hahne, a spokesman for the Lower Saxony agriculture ministry, earlier told the Associated Press news agency that many restaurants in which people ate before becoming ill had recently taken delivery of the sprouts. [Guilt by association]

He said authorities would still maintain a warning against eating tomatoes, cucumbers or lettuce.

The health ministry in Berlin said it was still waiting for results from tests on the beansprouts, Germany’s DPA news agency reported.

And the head of the Robert Koch Institute (RKI), Germany’s national disease centre, was also reported as saying that the cause of the outbreak could not yet be confirmed.

So: are sprouts the cause?

By this time, the outbreak is slowing down as the contaminated foods make their way through the food supply.

Could this happen here?  You bet.

If ever there was a time to give the FDA more resources, now is it.  The FDA now has the authority to impose standard food safety procedures on food producers and to require safety measures for the foods we import.   But Congress wants to cut the agency’s budget, and badly.

Now would be a good time to let congressional representatives know that we need a stronger FDA.   And while you are at it, let the USDA know that you think it would be a good idea to regulate other forms of toxic E. coli as adulterants in the same way they regulate E. coli 0157:H7. There is plenty government could do right now to protect us from outbreaks like this one.

A word about sprouts:

How come sprouts are such frequent sources of food safety problems?

Sprouts are grown from tiny seeds that are impossible to wash thoroughly enough to ensure that they are free of harmful bacteria.  The seeds are sprouted in water that must be changed several times a day.  This water is an excellent growth medium for bacteria.  That is why FDA guidance says sprout producers ought to test the wash water for harmful bacteria.

Under the new legislation, the FDA has the authority to enforce this guidance.  But does it have adequate personnel?  Unlikely, given the current stance in Congress.

This just in:  No, it’s not sprouts, according to this bulletin from Food Chemical News:

The latest news, reported this morning by both the Associated Press and BBC, is that 23 of 40 samples of organic sprouts taken from the Gaetnerhof farm in the Lower Saxony region of Germany have tested negative for the bacteria. Tests on the other samples have yet to be returned.

San Francisco Chronicle column: food plate, of course

My monthly (first Sunday) San Francisco Chronicle Food Matters column is on guess what?  This will be the last post on the new food icon for a while at least, I promise.

Food plate icon improvement of pyramid


 

 

 

 

 

 

 

 

Q: What’s the big deal over the government’s new food icon? A plate? That seems really boring.

A: The Department of Agriculture’s plate may look banal, but it is a key part of first lady Michelle Obama’s healthy eating campaign and I see it as a big step forward. Unlike the 2005 MyPyramid, this one is mostly about food, is easy to understand, and does not require use of a computer.

The plate does a better job of reflecting current thinking about healthy diets than previous guides. Its four sectors are unequal. Vegetables get the most space, and dairy – a discretionary choice – is off to the side.

You are to pile half your plate with fruit and vegetables, and a quarter with grains (half of them whole grains). All these come from plants.

I’m less happy about the sector marked “protein.” Protein is not a food. It is a nutrient.

USDA must think everyone knows that “protein” means beans, poultry and fish, as well as meat. But grains and dairy, each with its own sector, are also important protein sources. The meat industry wants you to equate protein with meat. It should be happy with this guide.

What I like best are the messages that come with the plate. My favorite? “Enjoy your food, but eat less.”

At last! Enjoyment is part of dietary advice. High marks to USDA for this one.

Other messages are designed to help you eat less while eating better. Smaller portions keep calories under control. Making half your plate fruits and vegetables is a profound switch from the six to 11 calorie-rich grain servings you were supposed to eat daily under the old MyPyramid.

For people who drink milk (really, you don’t have to), switching to low-fat is an effective way to save on calories, and whole grains are better for health than refined, rapidly absorbable starches that behave like sugars in the body.

So far, so good. But next come the politically charged “foods to reduce.” Here, the USDA is leaning in the right direction, but still pulling punches. USDA tells you to reduce sodium from soup, bread and frozen meals, but says nothing about salty snacks or other sodium-laden processed foods. This is a glaring omission.

And the final principle – “drink water instead of sugary drinks” – puts naturally sweet fruit juices (fine in small amounts) in the same category as sugar-added juice drinks, sports drinks and sodas, which ought to be reserved for occasional treats.

Let’s give USDA credit for going as far as it could without directly confronting the processed-food and soft-drink industries.

Optimist that I am, I think the icon has plenty for everyone to work with. It emphasizes the positives – fruits, vegetables, whole grains – and leaves lots of room for enjoyment. You can pile whatever foods you like on that plate as long as they fit within their assigned sectors.

Best of all, you do not have to count numbers of servings. If you want to control the size of your servings, just use a smaller plate.

Consider the alternatives. From 1958 until 1979, the USDA’s uncontroversial Four Food Groups advised eating two or three servings a day from dairy, meat, fruits and vegetables, and breads and cereals – half the plate from animal-source foods.

In 1979, in an effort to help reduce dietary risks for chronic diseases, USDA stacked the groups with plant foods above animal foods, eliciting a furor that led USDA nutritionists to begin a 12-year project to research a new food guide.

USDA released a food guide Pyramid in 1991, withdrew it under protest from meat producers, and re-released it a year later. Meat and dairy producers did not like being at the “eat less” top of the Pyramid. Nutritionists thought it promoted too many servings of high-calorie grains.

In 2005, the USDA replaced that Pyramid with the unobjectionable, food-free MyPyramid. This was impossible to teach (you had to know what each color stood for), eliminated any sense that it is better to eat some foods than others, and required a computer to personalize your own diet.

USDA officials say they spent about $2 million to research and test the new plate logo, create its website, and publicize it. This is a lot or a little depending on your perspective, but a plate is not exactly a new concept. The American Diabetes Association, American Institute for Cancer Research and Canadian government have all used similar plant-focused plates for years. The Physicians Committee for Responsible Medicine has one with a similar design but 100 percent vegetarian.

We can argue over nutritional details, but I think USDA’s plate-plus-messages works better than anything it has done before. The plate works for health and for disease prevention. It took courage to make half of it fruit and vegetables. That’s real progress.

Now the challenge is to Congress: How about fixing agricultural policies so they support these recommendations?

Tony Kushner: Respond to the planet’s cries for help

The playwright Tony Kushner gave his much fought over graduation speech at John Jay College yesterday.  I could not find the complete text online, but here’s what the New York Times says he said (with some editing):

Engage with society’s thorniest issues…find the human in yourself by finding the citizen in yourself, the activist, the hero in yourself.You face a beset and besieged world…Rspond to the planet’s cries for help.

There’s injustice everywhere. There’s artificial scarcity everywhere. There’s desperate human need, poverty and untreated illness and exploitation everywhere.

Everywhere in the world is in need of repair.  So fix it.

Solve these things.

And what does this have to do with food politics?  Everything.  It’s what the food movement is about.

Everybody loves MyPlate. Really?

I’ve been collecting public reactions to MyPlate, not least because I’m quoted in many of them.

The USDA collected supportive blurbs from a wide ranging group of supporters (mine among them)

Weight Watchers saluted the new icon in a full-page ad in the Washington Post

The Los Angeles Times covered it (I’m quoted)

The New York Times covered it (I’m quoted)

The Washington Post covered it (I’m quoted)

The Journal of the American Medical Association (JAMA) covered it (I’m quoted)

The New York Daily News covered it (I’m quoted)

The Des Moines Register covered it (I’m quoted)

USA Today covered it and published a photo of the plate with not-quite-fitting food models (I’m quoted)

ObamaFoodorama covered the many restrictions on using the plate (I’m quoted)

FoodNavigator.com covered it, focusing on the protein issue (I’m quoted)

Marian Burros wrote about it for Rodale (I’m not quoted).  She points out:

First of all, the complexities of good nutrition haven’t disappeared. You can find some of them at ChooseMyPlate.gov. And there are factors contributing to obesity—the unhealthy practices of the food industry, the presence of obesogens in the environment, an unsustainable food system to name a few—that won’t go away just because the pyramid is gone.

The American Heart Association supports it.

The American Dietetic Association supports it:

As we have in past years, the American Dietetic Association was deeply involved in the development of the 2010 Dietary Guidelines. And we will use the Guidelines and the new MyPlate to provide the unequalled advice and services of registered dietitians to individuals and communities alike.

Unsurprisingly, the produce industry loves it, according to The Packer and the trade association, United Fresh.

The meat industry spins it (MeatPoultry.com):

We are pleased that the new food icon unveiled today…affirms in a clear and simple fashion that protein is a critical component of a balanced, healthy diet….Lean meat and poultry products are some the most nutrient rich foods available, are excellent sources of complete protein, iron and zinc and maintain an excellent nutrition per calorie ratio.

Amber Healy of Food Chemical News (the site is only open to subscribers) has collected a bunch of food industry responses.  Here are some excerpts:

Jeane Wharton, executive director of the U.S. Dry Bean Council, couldn’t be more delighted with Thursday’s news.  “Beans are a great protein, and they’re also a vegetable,” says Wharton, who observes that her industry’s product benefits twice from the new image.

The American Bakers Association joined in with their praise of the plate, especially for grains “appropriately occupying a large portion on the dinner plate,” which shows that the agencies responsible for nutrition advice “are making a strong statement regarding the importance of grains as the foundation of a healthy lifestyle.

The National Dairy Council, National Milk Producers Federation, International Dairy Foods Association and Milk Processor Education Program (MilkPEP) also praise the new image in a statement released Thursday. While dairy isn’t included on the plate directly, the importance of dairy products in a healthy diet is clear, they say.

“Dairy foods are rightfully being recognized — from the school house to the White House — as an important part of everyone’s diet,” says Jerry Kozak, NMPF’s president and CEO. “USDA’s new icon, with a simple visual metaphor of a serving of dairy products alongside a plate, says it’s vital to consume three servings of low-fat and fat-free dairy foods every day.” [Really?  Vital?  That’s not how I read it.]

Last but not least, Andy Bellatti in his Small Bites blog and Melanie Warner on BNET provide excellent analyses of the disconnect between MyPlate recommendations and current agricultural policies—both coming from the same, historically schizophrenic USDA.

You think “schizophrenic” is too harsh?  The Physicians Committee for Responsible Medicine explains why agricultural policy needs a fix.

Deconstructing the USDA’s new food plate

I attended the launch of the new food icon this morning, and the press conference following it (which featured Red Rooster chef Marcus Samuelson).

 

 

 

 

 

 

 

 

 

As USDA Secretary Tom Vilsack explained, we have an obesity crisis in America that imperils our nation’s national security, economic vitality, and health care system.  It’s time for action.

I got a preview of the design on a conference call last week (while I was in Spain) and took a screen shot:

 

 

 

 

 

 

 

 

 

 

 

 

This may not look much like action, but it is a sharp departure from previous USDA icons (which USDA has delightfully put online).   These mostly emphasize the importance of meat and dairy foods (the 1992 Pyramid was an exception, which was why the Bush II USDA got rid of it).

Before yawning, consider its strengths:

  • It is easy to understand (as Mrs. Obama explained, even a child can use it).
  • Vegetables comprise the largest sector.
  • Together, vegetables and fruits are half the plate.
  • You can put whatever foods you like on that plate.
  • You don’t have to count servings or worry about portion size (if the plate isn’t too big).
  • Dairy foods–a discretionary group–are off to the side.

My one quibble?  Protein.  I’m a nutritionist.  Protein is a nutrient, not a food.  Protein is not exactly lacking in American diets.  The average American consumes twice the protein needed.  Grains and dairy, each with its own sector, are important sources of protein in American diets.

Why protein?  USDA used to call the group “meat” even though it contained beans, poultry, and fish.  The meat industry ought to be happy about “protein.”  Meat producers have spent years trying to convince Americans to equate meat with protein.

And USDA says its consumer testing (as yet unpublished) indicated that the public understood “protein” to cover diverse food sources.

According to William Neuman’s report in the New York Times, USDA official Robert C. Post said that:

U.S.D.A. had spent about $2 million to develop and promote the logo, including conducting research and focus groups and creating a Web site. Some of that money will also be used for the first year of a campaign to publicize the image.

I would like to see that research.  Post told me that the research would be published on the website within the next few days.  I look forward to seeing it.

One other point: consider the alternative.  Just for fun, here’s the plate the USDA was considering in its last efforts to try to get rid of the Pyramid in 1991.  We have Marian Burros, then at the New York Times, to thank for rescuing the Pyramid that came out in 1992.

 

 

 

 

 

 

 

 

 

 

The next step, of course, is to bring agricultural policy in line with the plate, meaning doing a much better job of supporting producers of vegetables and fruits.  This is part of Secretary Vilsack’s plan for repopulating and revitalizing rural America—a goal that I strongly support.

Given the pushback against public health that is happening in Congress this week—Cut school lunches! Cut WIC! Get rid of nutrition recommendations! Go easy on tobacco and antibiotics!—the more I think it took courage for USDA to do this.

Let’s hope USDA can stand up to the heat.

What will USDA’s food plate look like?

According to William Neuman’s report in the New York Times, a USDA official, Robert C. Post, said the new food guide would be a plate and that it would serve educational purposes :

The agency would use the plate to get across several basic nutritional messages, including urging consumers to eat smaller portions, switch to low-fat or fat-free milk and drink water instead of sugary drinks.

A plate with half devoted to fruits and vegetables is not exactly a new concept.

The American Diabetes Association has been using this plate as  a food guide:

 

 

 

 

 

 

The American Institute for Cancer Research uses this one:

 

 

 

 

 

 

 

Canada’s food guide is translated into this plate:

 

 

 

 

 

 

 

And the Physicians’ Committee for Responsible Medicine has an elegantly designed 100% plant-based plate for vegetarians and vegans:

 

 

 

 

 

 

 

And here’s what CNN thinks the new USDA food icon will look like:

 

 

 

 

 

 

 

 

Can the USDA improve on the existing versions?  Does CNN have it right?

I’ll be in Washington tomorrow to find out.  You can be there virtually at www.cnpp.usda.gov.

MyPyramid R.I.P.

On May 26, the USDA announced that it will be releasing a new “food icon” to replace the foodless and useless 2005 MyPyramid:

 

The USDA’s press announcement explained:

The 2010 White House Child Obesity Task Force called for simple, actionable advice to equip consumers with information to help them make healthy food choices. As a result, USDA will be introducing the new food icon to replace the MyPyramid image as the government’s primary food group symbol. It will be an easy-to-understand visual cue to help consumers adopt healthy eating habits consistent with the 2010 Dietary Guidelines for Americans.

What will the new icon look like?  The USDA isn’t saying, but William Neuman of the New York Times did some sleuthing.  According to his account:

The circular plate, which will be unveiled Thursday, is meant to give consumers a fast, easily grasped reminder of the basics of a healthy diet. It consists of four colored sections, for fruits, vegetables, grains and protein, according to several people who have been briefed on the change. Beside the plate is a smaller circle for dairy, suggesting a glass of low-fat milk or perhaps a yogurt cup.

And WebMD scored an interview with Robert C. Post, PhD, deputy director of the USDA Center for Nutrition Policy and Promotion, who gave additional hints:

“There will be a ‘how-to’ that will resonate with individuals. That is the behavioral part that is needed. We need to transcend information — ‘here’s what the science says’ — and give people the tools and the opportunities to take action.”

He referred to six how-to messages to guide healthy eating that were released with the 2010 Dietary Guidelines, and which I enthusiastically posted when the Guidelines were released (I was disappointed that they weren’t actually part of the Guidelines):

Balancing Calories

• Enjoy your food, but eat less.

• Avoid oversized portions.

Foods to Increase

• Make half your plate fruits and vegetables.

• Switch to fat-free or low-fat (1%) milk.

Foods to Reduce

• Compare sodium in foods like soup, bread, and frozen meals—and choose the foods with lower numbers.

• Drink water instead of sugary drinks.

A bit of history:

From 1958 until 1979, the USDA’s food guide was sort of a rectangle illustrating four food groups: Dairy, meat, fruits and vegetables, breads and cereals.  In 1979, USDA introduced a highly controversial design with food groups stacked on top of each other, with the plant-food groups at the top and the animal-food groups underneath (the producers of these foods did not like that).

Beginning in 1980, the USDA conducted an extensive research project to develop a new design—the pyramid—which it released in 1991 and withdrew immediately under pressure from meat producers.

In 1992, after a year of extraordinary controversy (recounted in my book Food Politics), the USDA released its highly controversial Food Guide Pyramid.

 

Why was it controversial?  The food industry objected that the Pyramid make it look as if you were supposed to eat more foods from the bottom of the pyramid than the top (which, of course, was its point).

Nutritionists objected that it encouraged eating too many servings of grains and, therefore, encouraged obesity.

In 2005, the USDA replaced it with the unobjectionable MyPyramid.  The food industry liked this one because it did not indicate hierarchies in food choices.  Most nutritionists that I know hardly knew what to do with it.  It required going online and playing with a website, and was unteachable in clinic settings.

I thought the 1992 pyramid had a lot going for it, particularly the idea that it’s better to eat some foods than others.  But MyPyramid was a travesty–hopelessly complicated, impossible to teach, and requiring the use of a computer.

Given this situation, the new image is highly likely to be an improvement.  If the new icon keeps the hierarchy, conveys concepts easily, and does not require online access, I will consider it a great step forward.

Fingers crossed.

Details about the release:

The announcement will be Thursday, June 2, 10:30 a.m. EDT. It will be live-streamed at www.usda.gov/live.   All information will be posted at www.cnpp.usda.gov.

I’ll be there.  Stay tuned.
