I subscribe to The Lancet, and always enjoy reading its editor’s weekly Offline column.  In October, editor Richard Horton wrote about how  government obesity policy needs to be based firmly on scientific evidence.

And what is that evidence?

On this question, the evidence is utterly clear.  Thanks to the work of the best scientific minds in obesity research, the most reliable evidence shows that the government’s plan should include taxes on unhealthy foods and beverages, front-of-pack traffic-light nutrition labeling, reductions of junk food and drink advertising to children, and school-based programmes to reduce television viewing and sugar-sweetened beverage consumption (Lancet, 2011;378:1451).

If you care about public health evidence, that’s what it shows.  But doing these things goes against the business interests of food companies and they are doing everything they can to oppose such science-based measures.

In the U.S., the Sunlight Foundation has just released a report detailing the amounts of money food companies have spent on lobbying to block federal attempts to set nutritional standards for marketing foods to children (see previous posts).

Big companies such as Nestle, Kellogg, Viacom, McDonalds, General Mills, and Time Warner have indicated on official reports that they have lobbied on the controversial proposed guidelines; all together such companies have reported spending more than $37 million on lobbying this year.

The Sunlight report lists reported lobbying expenses (for example, Coca-Cola $4.7 million, General Mills $660,000).  It also points out that

…Over all public relations were handled by Anita Dunn, formerly communications director at the Obama White House, at the firm SKDKnickerbocker Consulting.

Anita Dunn is of special interest because of her previous position at the White House.  Now she’s working for the not-so-loyal opposition.  Marian Burros reported on this switch for Politico:

Dunn, who served as White House communications director, is a senior partner at SKDKnickerbocker Consulting, which is handling public relations for the food industry’s campaign. Switching sides isn’t uncommon in the incestuous world of Washington consulting and lobbying, and the food industry coalition seeking to scuttle the voluntary guidelines argues that they are actually enforceable regulations in disguise that could lead to billions in lost sales.

Dr. Horton’s comments in Lancet imply that the British government isn’t doing much better.

As for the European Union (EU),  Food Chemical News reported on December 8 that major food companies— McDonald’s, Burger King, Coca-Cola, Danone, Kellogg, Mars, Nestlé, PepsiCo, Procter & Gamble and Unilever, as well as the European Snacks Associations—have just pledged to promote only healthful products on their websites aimed at children under age 12.

By “healthful,” they mean products that meet “better-for-you” criteria.  Food Chemical News cites a study suggesting that European children now see 79% less advertising of really bad junk foods on kids’ TV than they did in 2005, and 29% less across all TV programs.

The study did not say whether sales of those products were down too. If not, this could explain the willingness of companies to extend the voluntary restriction to websites aimed at very young children.

All of this would be much simpler for parents if governments paid attention to the research.  If they did, they would:

• Tax unhealthy foods and beverages
• Require traffic-light front-of-pack labels
• Stop junk food and drink advertising to children
• Institute programs to reduce television viewing
• Institute programs to reduce sugar-sweetened beverage consumption

Taken together, these might actually make some progress in reducing childhood obesity.

Food Navigator reports that UK experts are demanding public debate and regulation of nanomaterials in foods.  Without that, they warn, nanotechnology risks “facing the same fate as genetically modified (GM) foods in consumer perceptions.”

Nanotechnology is about manipulating materials on the scale of atoms or molecules, measured in nanometers (nm), one billionth, or 10⁻⁹, of a meter.

Many companies are already using nanomaterials in agriculture, food processing, food packaging, and supplements.  This is not something the public has heard much about.  Food companies often don’t know whether or not they are using these materials.

Nanotechnology science is new, and the industry is unregulated.

The FDA’s nanotechnology web page links to a quite thorough 2007 report from a task force,  but the agency’s only guidance to date tells companies how they can find out whether they are using nanomaterials.

Jumping into that gap, As You Sow has issued a Sourcing Framework for Food and Food Packaging Products Containing Nanomaterials.

As You Sow says:

Not only is this technology unregulated and untested for its implications on public health but companies may not even be aware if they are using products made with nanomaterials….In consultation with food companies such as: Kraft, McDonald’s (which has adopted a “no nano” policy), Whole Foods, Yum! Brands, and Pepsi, the nonprofit organization As You Sow developed this practical tool which clearly outlines what companies should ask their suppliers regarding the safety of products containing nanomaterials.

The report fills an important gap.  Companies using this technology should be telling the public more about it.  Nanotechnology is technical, difficult to grasp intuitively, “foreign,” and not under personal control.  This places it high on the scale of “dread-and-outrage.”

Does it belong there?  Who knows?  But the sooner its risks and benefits are assessed, the better.   Otherwise it risks becoming the next GMO in public perception.

Publicly traded companies cannot simply make a profit.  They must grow profits and report growth to Wall Street every 90 days.  This requirement is tough on all corporations, but especially tough on those selling food.  People can only eat so much.

To expand sales, food companies desperately seek new markets.  Last week, The Guardian and the Wall Street Journal described how food corporations are marketing processed foods to the poorest inhabitants of developing countries.

According to The Guardian,

Nestlé is using a floating supermarket to take its products to remote communities in the Amazon. Unilever has a small army of door-to-door vendors selling to low-income villages in India and west and east Africa. The brewer SABMiller has developed cheap beers in some African countries as part of a “price ladder” to its premium lager brands, and, as a leading Coca-Cola bottler and distributor, is aiming to double fizzy drinks sales in South African townships.

Last year 39% of acquisition deals by consumer goods companies were in emerging markets, compared with just 1% in 2008, according to the Grocer’s OC&C Global 50 league table.

The Wall Street Journal follows a salesman in South Africa who is “digging for his gold” in poor neighborhoods:

While Nestlé’s usual sales staff focus on filling shelves of big supermarkets, Mr. Mugwambane and 80 other salespeople like him hunt for tiny shops across South Africa that will buy such Nestlé products as baby food and nondairy creamers, often in single-serving packages that appeal to Africa’s price-sensitive customers.

…Nestlé says it expects 45% of its sales to come from emerging markets by 2020, up from roughly 30% now.

From the standpoint of food companies, says The Guardian, this is about “finding innovative ways to give isolated people the kind of choices the rich have enjoyed for years and are providing valuable jobs and incomes to some of the most marginalised.”

Baby food and nondairy creamers?

Maybe selling items like these brings jobs to some people, but it also brings nutrient-poor diets, obesity, and the resulting chronic diseases to those populations.

The ultimate costs will be high.

Grist and Food and Tech Connect have excellent reports on last week’s Farm Bill Hackathon.  This event brought together farm bill experts and designers to try to produce materials that make farm bill issues accessible.

The terrific winning entry: A Clean Farm Bill of Health slideshow illustrating the contradiction between USDA dietary advice policy and that for farm supports.

I could not participate in the Hackathon but having just taught a class on the farm bill I know what I’d like to have: a complete text of the farm bill annotated to include all of the relevant information.

The 663-page 2008 farm bill is readily accessible online, but it is unreadable (by me at least).   This is because it refers to previous bills and other Acts of Congress, which in turn refer to previous bills and Acts, in some cases going back to 1933.

You don’t believe me?  Try this entirely typical section, chosen at random:

SEC. 12001. DEFINITION OF ORGANIC CROP.
Section 502(b) of the Federal Crop Insurance Act (7 U.S.C.
1502(b)) is amended—
(1) by redesignating paragraphs (7) and (8) as paragraphs
(8) and (9), respectively; and
(2) by inserting after paragraph (6) the following:
‘‘(7) ORGANIC CROP.—The term ‘organic crop’ means an
agricultural commodity that is organically produced consistent
with section 2103 of the Organic Foods Production Act of 1990
(7 U.S.C. 6502).’’.

It would be so nice to have a text that gives the relevant information in one place: what the Federal Crop Insurance Act says, what paragraphs 7 and 8 are all about, and what’s in section 2103 of the 1990 Act.

Hackers: anyone want to take this on?

The Environmental Working Group (EWG) is getting interested in childhood obesity.  It released a report on sugars in kids’ breakfast cereals.

The report shows—no surprise—that kids’ cereals are really cookies in disguise, typically 40% -50% sugars by weight.   Kellogg’s Honey Smacks topped the list at 55%.

Michele Simon’s analysis of the report notes that these levels don’t even meet Kellogg’s commitment to responsible marketing, a pledge to “apply science-based Kellogg Global Nutrient Criteria to all products currently marketed to children.”

I’ve been reading reports like this since the 1970s when Center for Science in the Public Interest published them at regular intervals.  Not much has changed.

Courtesy of Kellogg, I have a collection of copies of Froot Loop boxes dating back to the year in which this cereal was first introduced.  I thought it would be interesting to check the sugar content.

Froot Loops, Sugar content, grams per ounce

In 2005, Kellogg tried a version with 1/3 the sugar—10 grams—but it didn’t sell and quickly disappeared.

Companies are trying to reduce the sugars by a little, but this seems to be the best they can do.  It’s not enough.

As the EWG press release explains, some cereals are better than others.   It notes that I recommend:

• Cereals with a short ingredient list (of additives other than vitamins and minerals).
• Cereals high in fiber.
• Cereals with little or no added sugars (added sugars are ingredients such as honey, molasses, fruit juice concentrate, brown sugar, corn sweetener, sucrose, lactose, glucose, high-fructose corn syrup and malt syrup).
• Even better, try fresh fruit and homemade oatmeal.

I don’t often write about pesticides, plasticizers, heavy metals or other such potentially toxic substances in food because there usually isn’t enough science available to draw firm conclusions about how much of them is OK to consume.

At high concentrations they are demonstrably toxic.  But in food and water, they appear in amounts measured as parts per billion (ppb) or trillion, and it is difficult to know how harmful they may be at such levels.

The big question: is there a threshold for harm or are they unsafe at any level of intake?  The history of regulation of such substances is one of constant reduction in levels considered safe.

They derive in large part from industrial processes, and attempting to regulate them confronts large and powerful industries eager to argue that low levels are safe.

Now Consumer Reports has tested samples of juice and finds levels of arsenic  higher than allowed in drinking water:

• 10% of the samples contained levels of arsenic that exceed EPA drinking-water standards of 10 ppb.
• 25% contained levels of lead greater than the FDA’s 5 ppb standard for bottled water.
• Most arsenic was inorganic, a form linked to cancer, cardiovascular disease, immune disorders, and type 2 diabetes.
• 35% of children age 5 and younger drink juice in amounts higher than recommended by pediatricians.
• No federal standards exist for amounts of lead and arsenic in juice.

This is a food systems issue.  Inorganic arsenic gets into food from soil contaminated with arsenic-containing herbicides and waste from animals and chickens fed arsenic-containing additives.

Consumer Reports says:

• FDA should set a standard for total arsenic in juice at 3 ppb and 5 ppb for lead.
• EPA should lower the 10 ppb drinking-water limit for arsenic.
• Parents should limit juice servings to small children.

What does the FDA have to say?

The Food and Drug Administration has every confidence in the safety of apple juice…small amounts of arsenic can be found in certain food and beverage products—including fruit juices and juice concentrates….there is no evidence of any public health risk from drinking these juices…FDA has been testing them for years [see the FDA’s Q and A].

As if this were not enough to worry about, Food Quality News reports increasing concern about the amount of arsenic in rice, the dangers of such levels for pregnant women, and the need to establish better standards for safe levels of arsenic in foods.

Consumer Reports is especially concerned about a study published in the Proceedings of the National Academy of Sciences linking rice consumption to levels of arsenic in the urine of pregnant women.   It notes that children in the U.S. typically are fed rice cereal as their first solid food, making them especially vulnerable to the effects of arsenic.

Arsenic gets into rice in the same way that it gets into apples and grapes, but rice is especially efficient in taking up arsenic from soil.

I see all this as further evidence that agricultural practices are key determinants of public health and that we badly need:

• More and better research on the effects of small amounts of arsenic, lead, pesticides, and other such toxins in food
• Research on how to remove such toxins from soil
• Federal safety standards for arsenic in foods and beverages; the Consumer Reports recommendations make sense
• Regulations that restrict use of arsenic drugs in animal agriculture and of pesticides containing arsenic
• Restrictions on the amount of juice and rice given to children

It’s great that Consumer Reports is doing this kind of research but federal agencies should be doing a lot more of it too.

I got a call yesterday from Sam Kass, the senior policy adviser on Michelle Obama’s Let’s Move staff, objecting strongly (an understatement) to my post about her new physical activity initiatives.

I interpreted her speech as a pullback from healthy eating initiatives.  “Eating better” is demonstrably bad for business.  The food industry much prefers “move more.”

Mr. Kass says no pullback was intended.  Instead, he said, this is an expansion of Let’s Move into another one of the program’s five essential “pillars.”

Pillars?

I did not recall anything about pillars.  I went to the Let’s Move website. Sure enough, there they are:

At the launch of the initiative, President Barack Obama signed a Presidential Memorandum creating the first-ever Task Force on Childhood Obesity….[Its] recommendations focus on the five pillars of the First Lady’s Let’s Move! initiative.

1. Creating a healthy start for children
2. Empowering parents and caregivers
3. Providing healthy food in schools
4. Improving access to healthy, affordable foods
5. Increasing physical activity

In February 2010, Mrs. Obama discussed these elements in her speech launching Let’s Move, although without using the word “pillars.”  The word also did not pop up in her speech discussing the new activity initiatives.

When I need help with this sort of thing, I consult Obama Foodorama,  a treasure trove of information about food at the White House.  Here’s what Let’s Move has done and is doing about the pillars:

1. Creating a healthy start for children: encouraging breastfeeding, Let’s Move Child Care, and other such programs
2. Empowering parents and caregivers: MyPlate and MiPlato, front-of-package labeling
3. Providing healthy food in schools: child nutrition legislation, Healthier US Challenge , salad bars in schools
4. Improving access to healthy, affordable foods: combating food deserts, reducing the price of fruits and vegetables, encouraging gardening, and green markets
5. Increasing physical activity: Presidential Active Lifestyle Award challenge (PALA) and the new initiatives

In the broader context of the Let’s Move pillars, a focus on physical activity makes sense.  It is an addition, not a substitution.

But Mrs. Obama’s speech did not frame it like that.  Instead, her speech implied that she had given up on healthy eating because it is too difficult (kids have to be forced to eat vegetables), leaving open the possibility that “eating better” is too hard to promote in an election year.

I wish her speech had placed the initiative in context.   Had it done so, it would not have been open to this kind of interpretation.

In what Obama Foodorama calls “a fundamental shift in the Let’s Move campaign” Michelle Obama announced in a speech last week that she will now focus on getting kids to be more active.

Apparently, she has given up on encouraging food companies to make healthier products and stop marketing junk foods to kids.

This shift is troubling.  Here’s why:

1.  The shift is based on faulty biology.

To lose weight, most people have to eat less whether or not they move more.   For example, it takes about three miles of walking to compensate for the calories in one 20-ounce soda.

Activity is important for health, but to lose or maintain weight, kids also need to eat less.  Sometimes they need to eat much less.  And discouraging them from drinking sugary sodas is a good first step in controlling body weight.

But eating and drinking less are very bad for business.  Food companies do all they can to oppose this advice.

2.  It undercuts healthy eating messages.

On the one hand, Mrs. Obama says that she disagrees with this assumption: “kids don’t like healthy food, so why should we bother trying to feed it to them.”

But her speech implies that kids won’t eat healthfully unless forced to:

I want to emphasize that last point — the importance of really promoting physical activity to our kids…This isn’t forcing them to eat their vegetables. (Laughter.) It’s getting them to go out there and have fun.

3.  It declares victory, prematurely.

Mrs. Obama says:

Major food manufacturers are cutting sugar, salt and fat from their products. Restaurants are revamping kids’ menus and loading them with healthier, fresher options. Companies like Walgreens, SuperValu, Walmart, Calhoun’s Grocery are committing to build new stores and to sell fresh food in underserved communities all across this country.

Congress passed historic legislation to provide more nutritious school meals to millions of American children. Our schools are growing gardens all over the place. Cities and towns are opening farmers markets. Congregations are holding summer nutrition programs for their kids. Parents are reading those food labels, and they’re rethinking the meals and the snacks that they serve their kids.

So while we still have a long way to go, we have seen so much good progress. We’ve begun to have an impact on how, and what, our kids are eating every single day.  And that is so important. It’s so important.

Really?  I’d say we’ve seen promises from food companies but remarkably little action.

Mrs. Obama’s speech fails to mention what I’m guessing is the real reason for the shift: “Move more” is not politically loaded.  “Eat less” is.

Everyone loves to promote physical activity.  Trying to get the food industry to budge on product formulations and marketing to kids is an uphill battle that confronts intense, highly paid lobbying.

You don’t believe this?  Consider recent examples of food industry opposition to anti-obesity efforts:

• Soda companies successfully defeated efforts to impose taxes on soft drinks.
• Food companies successfully defeated efforts by four federal agencies to set voluntary standards for marketing foods to children.
• Food companies successfully lobbied Congress to pass a law forbidding the USDA from setting standards for school meals regarding potatoes, tomato sauce, and whole grains.  The result?  Pizza tomato sauce now counts as a vegetable serving.
• McDonald’s and  Burger King evaded San Francisco’s new rules restricting toys with kids meals by selling the toys separately for ten cents each.

The political cost of fighting the food industry is surely the reason for the change in Mrs. Obama’s rhetoric.  Now, she agrees that kids won’t eat vegetables unless forced to.

But in March 2010 Mrs. Obama warned Grocery Manufacturers Association:

We need you…to entirely rethink the products that you’re offering…, the information that you provide about these products, and how you market those products to our children….This isn’t about finding creative ways to market products as healthy.

The food industry understood those as fighting words.  It fought back with weapons at its disposal, one of which is to deflect attention from food by focusing on physical activity.   It now has White House endorsement of this deflection.

I’m all for promoting physical activity but the refocusing is a loss, not a win, in the fight against childhood obesity.
