On the eve of the Olympics, The Lancet has published a special issue on physical activity.

Since this is too small to read:

Physical activity:

Worldwide, we estimated that physical inactivity causes 6-10% of the major non-communicable diseases…physical inactivity seems to have an effect similar to that of smoking or obesity.

The issue is packed with carefully researched commentaries and papers on the benefits of physical activity.

But it starts out with a tough editorial,  Chariots of Fries:

The Games should encourage physical activity, promote healthy living, and inspire the next generation to exercise. However, marring this healthy vision has been the choice of junk food and drink giants—McDonald’s, Coca-Cola, and Cadbury’s—as major sponsors of the event

Health campaigners have rightly been dismayed. On June 20, the London Assembly (an elected body that scrutinises the work of the Mayor of London) passed a motion urging the International Olympic Committee (IOC) to adopt strict sponsorship criteria that exclude food and drinks companies strongly associated with high calorie brands and products linked to childhood obesity.

Meanwhile, the UK’s Academy of Medical Royal Colleges has said that the presence of McDonald’s and Coca-Cola at the 2012 Games sends out the wrong message to children.

This morning, I received an e-mail from the Coca-Cola Civic Action Network (CAN), described on its website as

a non-partisan group whose purpose is to provide information to the Coca-Cola family about national, state, and local issues that could affect us.  Whenever an issue comes up that could change our day-to-day lives, CAN goes to work getting important information to its members.

The message lists Coca-Cola’s Olympic actions:

• Olympic Torch Relay
  Integrated Marketing Campaign, Move to the Beat
• Global Anthem, Documentary & Global TV Commercial
• Coca-Cola Presents, Beat TV
• Digital & Mobile Application
• Games-time Refreshment
• Powerade Sports Academy
• Physical Activity Programs
• Legacy in sustainability

The e-mail says:

Coca-Cola will be refreshing and hydrating the 14,000 athletes, 7,000 officials, 20,000 workers and volunteers and more than 6 million spectators that are expected to flock to the Olympic Park. From one product in one size offered at the 1948 Olympic Games, to today’s more than 500 brands at the London 2012 Games, Coca-Cola will provide the widest range of drinks and sizes ever offered at an Olympic or Paralympic Games, to suit every lifestyle and hydration need.

Should soda and fast-food companies be sponsoring the Olympics?  Is this the message we want sent to kids?  I don’t think so.  You?

Center for Science in the Public Interest (CSPI) launched Food Day yesterday with a splendid lunch right in the middle of Times Square.  I got to be one of the lucky eaters.

The purpose of Food Day is to promote discussion of critical issues in agriculture, food, nutrition, and health.  Its goals:

• Promote healthy eating.
• Support sustainable farms.
• Expand access to food and alleviate hunger.
• Reform factory farms.
• Curb junk-food marketing to kids.

For half an hour, it got big-time billboard coverage.

The lunch was nutritionally correct and quite delicious, thanks to Ellie Krieger who did the menus and is posed here with Mario Batali.

Tom Farley, director of New York City’s Health Department, gave the opening speech with updates on his department’s new “cut down on sodas” campaign.  For example: One soda a day translates to 50 pounds of sugar a year, and you have to walk three miles to burn off the calories in one 20-ounce soda!  He’s here with Michael Jacobson who has directed CSPI since the early 1970s.

Tom Chapin sang from his album for kids, “give peas a chance.”

It was all anyone needed to be inspired to join the food movement and sign up for the food day campaign!

Later addition: Mike Jacobson sent this one with Morgan Spurlock.

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.

I had best comment on this before anyone asks.   First Lady Michelle Obama wants to do something about childhood obesity and has gone into action.  She announced her “Let’s Move” initiatives accompanied by much fanfare.  Check out:

• The USDA Secretary’s promise to ask Congress to get junk food out of schools and provide breakfast and lunch to more kids (the New York Times discusses some of the reactions)
• The President’s appointment of a task force on childhood obesity
• The Ad Council’s public service announcements
• USA Today’s neat graphics on rising rates of childhood obesity
• USA Today’s maps of the environment of childhood obesity
• The USDA’s website atlas of the environment of food choice
• The American Beverage Association’s promise to put calories on the front of soft drink packages
• The American Academy of Pediatrics commitment to aid the White House effort
• And the Surgeon General’s Vision that I commented on two days ago

This is big news.  I see much to admire here.  The campaign focuses on kids.  It is sensitive to political realities (it’s called the uncontroversial “Let’s Move,” not the inflammatory “Let’s Eat Less” or “Let’s Eat Better”).  It’s brought a large number of groups on board (the New York Times account emphasizes this point).  It aims to do something useful about school food and food “deserts” (areas without grocery stores).  And it derives directly and explicitly from the White House garden.

I wasn’t able to watch the press conference but I hear that Will Allen was an invited speaker.  Allen is the charismatic and highly effective head of Growing Power, which runs urban farms in Milwaukee and Chicago.  I’m told he said:

• It’s a social justice issue.
• Every child in this country should have access to good food.
• We have to grow farmers.

Yes!

Before the announcement, Marian Burros wrote in Politico.com about the barriers this effort will face (I’m quoted in her article).   And the Los Angeles Times discussed the enormous and enormously successful lobbying effort undertaken by the soft drink industry against soda taxes.  It predicted that the First Lady would not mention soda taxes when she announced her obesity campaign.  Indeed, she did not.

But she did say:

The truth is our kids didn’t do this to themselves.  Our kids didn’t choose to make food products with tons of fat and sugar and supersize portions, and then to have those foods marketed to them wherever they turn.

So let’s call this campaign a good first step and give it a big round of applause.  I hoping everyone will give it a chance, help move it forward in every way possible, and keep fingers crossed that Mrs. Obama can pull it off.

I recently received this request from Daniel posted to Feedback:

Would you mind writing a blog post on the new surgeon general’s obesity report? …Is there a food politic element to why this has gone under the radar? …I find it ironic that Michael Pollan’s Food Rules generated substantially more press than a report by the United States Surgeon General.

I’m not surprised.  Pollan’s book is a hot best seller (it’s #1 on Amazon books, and for good reason, in my opinion).   The need to prevent obesity and how to do it is not exactly front-page news.  And the new Surgeon General, Dr. Regina Benjamin, is still relatively unknown as a political force.

But let’s give Dr. Benjamin credit for taking on obesity in one of her first public actions: the release of “Vision for a Healthy and Fit Nation.”   The Vision, which comes with a press release and a fact sheet, recommends these actions to prevent obesity:

1. Reduce consumption of sodas and juices with added sugars.
2. Reduce consumption of energy dense foods that primarily contain added sugars or solid fats.
3. Eat more fruits, vegetables, whole grains, and lean proteins.
4. Control your portions.
5. Drink more water.
6. Choose low-fat or non-fat dairy products.
7. Limit television viewing time and consider keeping televisions out of children’s rooms.
8. Become more physically active throughout the day.
9. Breastfeed exclusively to 6 months.

These are all useful suggestions but we have heard them before.  The real issue is how to achieve them.  Here, the report disappoints.

The first two items should have grabbed attention: targeting soda reduction as as the first line of defense against obesity, and eating less junk food (my translation) as the second.

But Dr. Benjamin assigns parents the responsibility for feeding kids healthfully.  Fine, but what about about public health approaches to reducing soda consumption?  To pick a non-random example, soda  taxes are under intense debate right now.  Does Dr. Benjamin weigh in on such approaches?  Alas, no.  Only on the second-to-last page does she summarize suggestions from the Centers for Disease Control and Promotion (CDC), among them:

• Increase availability of healthy, affordable food and beverage choices in public service venues.
• Improve geographic availability of supermarkets in underserved areas.
• Improve access to fresh fruits and vegetables by providing incentives for the production, distribution, and procurement of foods from local farms.
• Limit advertisements of less-healthy foods and beverages.

I wish the report had focused on such ideas, instead of leaving them to an afterthought and personal responsibility. It’s great that the nation’s doctor cares about obesity but her Vision isn’t nearly as tough or realistic as it needs to be.  For that, we need the CDC or the report on food marketing to kids that the Institute of Medicine produced in 2005.

In 2001, Surgeon General David Satcher released the first government report on preventing obesity.  It got press. If this one didn’t, it could well be because it doesn’t break enough new ground.  Surely, it’s high time we got beyond blaming parents and instead started focusing on the need to create a food environment that makes it easier for parents and everyone else to make better food choices and be more active.

I hear that Michelle Obama will soon announce (tomorrow?) a new program to address childhood obesity.  I’m hoping that her program will take on some of the factors in the food environment that make it so difficult for everyone to eat healthfully.

I usually don’t say much about the physical activity side of the obesity equation, mainly because overeating calories is so much greater a contributor to weight gain.  But don’t get me wrong.  I favor “move more” as much as “eat less,” especially for kids.

I’m dismayed by how kids these days are basically under house arrest.  So, apparently, is the American Academy of Pediatrics, which has just produced a thought-provoking report about how to create a kid-friendlier “built environment” (public health-speak for sidewalks, playgrounds, and the other ways cities are constructed to discourage physical activity).

My favorite statistic from the report: In 1969, about 41% of kids walked to school on their own.  Today it is 13% on average and just 5% in some areas.

Try this for comparison: When I was 8 years old and living in Manhattan, I walked 6 blocks to school in the morning, came home for lunch, walked back to school after lunch, and then walked home, got my bicycle, and headed off to the park – unsupervised – and lived to tell about it.  I took subways – by myself – to piano lessons.  After school, I was sent out to play and expected to stay out until dinner time.

Well, society has changed and it is hard to imagine letting children so young do that today.  The question is what to do about it.  Pediatricians urge us to ask that question.  And about time, too.

If the FDA is now going after health claims (see yesterday’s post), will it also start going after dietary supplements?  These, as I explained in my most recent column in the San Francisco Chronicle, get to make all kinds of unsubstantiated claims without the FDA being able to do much about them.  More and more evidence is coming in suggesting that supplements can be harmful as well as ineffective.   The latest example: antioxidant supplements are said to interfere with the beneficial effects of physical activity.    Will such studies encourage the FDA to insist that manufacturers demonstrate safety and efficacy before they put supplements on the market?  That would be a refreshing change, no?

While the new website was in production, I got a bit caught up on my reading.  Here’s what’s been happening on the obesity front.

Middle-age spread: eat less or else! A new study proves what every woman over the age of 50 knows all too well: you just can’t eat the way you used to without putting on the pounds.  Muscle mass declines with age, calorie needs do too.    Activity helps some, but not enough.  I think it’s totally unfair, by the way, but I’m guessing the same thing happens to men (but they have more muscle to begin with).  Alas.

Turn off the TV: Common Sense Media looked at 173 studies of the effects of watching TV on child and adolescent health.  Of 73 studies examining correlations between TV-watching and obesity, 86% found strong associations.  TV-watching was also strongly associated with such unfortunate outcomes as cigarette smoking, drug use, early sexual activity, and poor academic performance.  Conclusion: if you want to encourage kids to be healthier, turn off the TV!

British government launched an anti-obesity campaign: The UK government’s Change4Life campaign is designed to promote healthier lifestyles.  This is causing much discussion, not least because of its food-industry sponsorship (uh oh).  Food companies are said to view the campaign as good for business (uh oh, indeed). The government wants everyone to help with the campaign by putting up posters and such, and its website is cheery.  Buried in all of this is some good advice, but most of it is phrased as eat better, not eat less or avoid.  That, of course, is why the food industry is willing to fund a campaign which, if successful, could hardly be in the food industry’s best interest.
