Environmental Working Group’s “dirty dozen”

The Environmental Working Group (EWG) has just published its 2011 guide to the most and least pesticide-laden fruits and vegetables.

The #1 “dirtiest”?  Apples.  The remedy?  Buy from the EWG “clean 15” list or buy organic.

The “dirty dozen” list, in order: Apples, Celery, Strawberries, Peaches, Spinach, Imported nectarines, Imported grapes, Sweet bell peppers, Potatoes, Domestic blueberries, Lettuce, Kale/collard greens.

The “clean 15” list of foods with the least pesticides: Onions, Sweet corn, Pineapples, Avocados, Asparagus, Sweet peas, Mangoes, Eggplant, Domestic cantaloupe, Kiwifruit, Cabbage, Watermelon, Sweet potatoes, Grapefruit, Mushrooms

How much should you worry about pesticides on foods?  As one reader asked,

Is it better to eat conventional fruits (cherries, berries and apples) and other veggies (peppers) that are on the “dirty” vegetable list or forego them altogether?

This is not an easy question to answer.  EWG recognizes that the science linking pesticides to health problems is limited (this is an understatement).  EWG bases its rankings on data published by USDA and FDA.  It considers:

  • Percent of samples tested with detectable pesticides
  • Percent of samples with two or more pesticides
  • Average number of pesticides found on a single sample
  • Average amount (level in parts per million) of all pesticides found
  • Maximum number of pesticides found on a single sample
  • Total number of pesticides found on the commodity

EWG explains that its

Shopper’s Guide is not built on a complex assessment of pesticide risks but instead reflects the overall pesticide loads of common fruits and vegetables. This approach best captures the uncertainties of the risks of pesticide exposure and gives shoppers confidence that when they follow the guide they are buying foods with consistently lower overall levels of pesticide contamination.

Most available research supports the health benefits of eating fruits and vegetables regardless of their pesticide loads.  Ken Cook, the president of EWG says:

We recommend that people eat healthy by eating more fruits and vegetables, whether conventional or organic,” says Ken Cook, president and founder of Environmental Working Group. “But people don’t want to eat pesticides with their produce if they don’t have to. And with EWG’s guide, they don’t.”

By EWG calculations, you can lower your pesticide intake by 92% if you avoid the dirty dozen.  No wonder.  How’s this for an observation: “Hot peppers had been treated with as many as 97 pesticides, followed by cucumbers (68) and greens (66).”  Who knew?

Where is the produce industry in all of this?  EWG reports that produce trade associations are working hand-in-glove with the pesticide industry to attempt to keep information about these chemicals out of the public eye.

I wish more research existed on the dose-response effects of pesticides and on their long-term effects on health, especially in children.  I cannot imagine that pesticides are good for health.  In high doses, they are demonstrably harmful to farm workers.

But what about the low doses on fruits and vegetables?  Here, the evidence for long-term harm is weak, uncertain, and unhelpful.

What to do?

On the personal side: if you want to avoid eating pesticides, you can stick with the EWG 15.  Washing produce before eating it is always a good idea even if it doesn’t get rid of all of the chemicals (USDA studies are done on washed produce).  When in doubt, buy organic.

As for the political, if ever there was a situation where more research was needed, this is it.  And isn’t it time for industrial food producers to find ways to use fewer pesticides?  Let the produce trade associations know that you don’t like their defense of potentially harmful chemicals and that you much prefer organic.

Addition, June 16: For anyone interested, here are the USDA’s pesticide announcements for the new data:

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?

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.

Who is responsible for dealing with poverty?

I don’t often respond to comments but this one about the political division caused by obesity is worth further discussion.

I truly resent your statement that Republicans don’t want to have an education, access to health care or access to nutritious food. Such statements not only undermine your credibility but contribute nothing to the discussion.

For the record, Republicans as just as committed to these things as the Democrats. The difference is that the Republicans don’t believe that it is the taxpayers responsibility to provide them.

If not taxpayers, who?  The writer does not say.

I thought of this question when I read the new report released by the NYC Center for Economic Opportunity. The center was established in 2006 by Mayor Bloomberg to seek evidence-based ways to reduce poverty in the city.

As the New York Times explains:

Without a flood of food stamps and tax benefits for low-income families, about 250,000 more New Yorkers would have slipped into poverty at the height of the recession…The center concluded that the poverty rate would have been three percentage points higher without federal tax programs passed in 2009 for low-income families and an aggressive city program to enroll New Yorkers who were not receiving public assistance but were eligible for food stamps, coupled with higher food stamp benefits.

Beyond personal damage, poverty is demonstrably bad for the health of cities.  Poor people do not buy much.  They cause social unrest.  They drain public resources.  Getting people out of poverty is sensible public policy and has been throughout history.

History also tells us that private charity is never adequate to meet the needs of the poor.

That’s why U.S. taxpayers support food stamp and other food assistance programs to the tune of close to $100 billion a year, as can be seen in the USDA’s budget figures.

The “aggressive city program” paid off.  At a time of economic crisis, poverty levels throughout America increased.  New York City’s did not.

Isn’t dealing with poverty a core function of government?  Isn’t some reasonable level of income equity a core feature of democratic society?

I think so, but await your opinions.

Update on organics

On March 02, USDA announced that it was revoking its accreditation of two certifying agencies, Certified Organic, Inc. (COI) and Guaranteed Organic Certification Agency (GOCA).

USDA says COI failed to

  • Communicate with hired inspectors about proper procedures or ensure they were adequately trained
  • Adhere to internal procedures according to their operational manual
  • Keep confidentiality agreements on file for all employees with knowledge about certification applicants or operations
  • Indicate on certificates the effective dates for organic certification,
  • Ensure adequate training for employees about the regulations
  • Provide clients with cost estimates including inspection fees
  • Clearly identify the company’s responsibility to pay for any required pre- or postharvest testing
  • Verify organic system plans against the actual practices of their certified operations

GOCA’s problems had to do with “persistent noncompliance,” including such things as “failure to require clients to use defined boundaries and border zones as required by the organic standards.”  This mayall  sound absurdly bureaucratic but it means the certifiers could be overlooking producers’ violations of organic standards.

You can track down the records of such things on the USDA’s website, and see the handful of other such enforcement actions at the National Organic Program’s site.

I’d say this is progress.  Organic producers are supposed to follow the rules of the National Organic Program, and to be inspected to make sure they do.  If the inspectors aren’t doing their job diligently, you won’t be able to tell whether the organic foods you buy are worth the premium prices.

This is a key point of a recent FoodNavigator story on the market for organics.  The U.S. industry is expected to go from $21.1 billion in 2010 to $36.8 billion in 2015.   How come?  Because of “the government’s monetary and regulatory support and increasing acceptance of organic food in the country.”

People will pay more for organics if they think the producer is credible.  Organics are about credibility.  That is why the USDA needs to fiercely enforce organic certification.   Doing so protects the industry.  The more of this sort of thing, the better.

Way to go GAO! A single food safety agency

Thanks to FoodSafetyNews for the heads up on the latest Government Accountability Office(GAO) attempt to get Congress to consolidate federal food safety functions on one agency.

The GAO’s latest 345-page report on how the federal government can save money lists its proposals in alphabetical order by area.  Agriculture comes first and, therefore, so does food safety.  You have to love the way GAO titles its sections: “Fragmented food safety system has caused inconsistent oversight, ineffective coordination, and inefficient use of resources.”

GAO has been saying this for 20 years.  In 1990, for example, it published reports on who does what in the federal government about food safety and the inconsistencies in oversight.

As I wrote in Safe Food: The Politics of Food Safety (2010),

Today, an inventory of federal food safety activities reveals a system breathtaking in its irrationality: 35 separate laws administered by 12 agencies housed in six cabinet-level departments….

At best, a structure as fragmented as this one would require extraordinary efforts to achieve communication let alone coordination, and more than 50 interagency agreements govern such efforts.

Among the six agencies with the broadest mandates, all conduct inspections and collect and analyze samples, and at least three–though not necessarily the same ones–have something to do with regulating dairy products, eggs and egg products, fruits and vegetables, grains, and meat and poultry.

Until recently, the system had no mission statement (for whatever such statements are worth) and it still does not have consistent rules, clear lines of authority, a rational allocation of resources, or standards against which to measure success.

With such a system, some issues–such as use of animal manure to fertilize food crops—inevitably fall between the cracks and are governed by no rules whatsoever.

Not much has changed in the subsequent 20 years, as this new report attests.  As is inevitably the case, some of the areas of overlap are simply absurd:

The 2008 Farm Bill assigned USDA responsibility for catfish, thus splitting seafood oversight between USDA and FDA. In September 2009, GAO also identified gaps in food safety agencies’ enforcement and collaboration on imported food.

Specifically, the import screening system used by the Department of Homeland Security’s Customs and Border Protection (CBP) does not notify FDA’s or FSIS’s systems when imported food shipments arrive at U.S. ports.

But the worst is the situation with shell eggs, seemingly unfixable, given the 2010 recall of 500 million eggs:

FDA is generally responsible for ensuring that shell eggs, including eggs at farms such as those where the outbreak occurred, are safe, wholesome, and properly labeled and FSIS [USDA] is responsible for the safety of eggs processed into egg products.

In addition, while USDA’s Agricultural Marketing Service sets quality and grade standards for the eggs, such as Grade A, it does not test the eggs for microbes such as Salmonella.

Further, USDA’s Animal and Plant Health Inspection Service helps ensure the health of the young chicks that are supplied to egg farms, but FDA oversees the safety of the feed they eat.

I repeat.  This is not a new issue.  The hope was that the food safety act passed in January would pave the way to establish a single food safety agency.  The GAO report, while urging its creation, doubts that it will cut costs.

But it might save lives.
