Europe rejects droves of health claims

In what the functional food industry refers to as a “bad day at the office,” the European Food Standards Agency (EFSA) rejected hundreds of health claims, particularly those for probiotics.  More recently, it rejected a claim that glucosamine prevents cartilege degeneration.  Hard as it may be for the food and supplement industries to believe, EFSA just can’t find scientific evidence to support those claims.

A representative of the company that applied for the glucosamine claims says his company now anticipates a loss in product sales, and complains that it had “invested quite heavily in this submission, in terms of effort and financial outlay.”

Too bad.

Why can’t they come up with the science to support those claims? For one thing, who would want to do the research?  Danone and Yakult have just announced two $50,000 grants to study probiotics.  This won’t go far and the sponsorship is an almost certain guarantee that the results will be just what the companies paid for.

Independent research is much more complicated.  Consider folic acid, for example.  The latest clinical trial of folic acid and colon cancer went to a lot of trouble to prove that folic acid supplements are harmless.  In most people, they have no effect on colon cancer, neither benefit nor risk.  Among the few people who had unusually low levels of the vitamin in their blood, the supplements appeared to have some protective effect.  You can interpret results like this either as evidence for no benefit or as evidence that folic acid supplements might benefit some people under some circumstances.

And that brings us to supplements again.  A trade association for supplement manufacturers says:

While it cannot be denied the food and supplement industry has entertained its fair share of cowboys, our concern is that the [EFSA] regulation goes so far as to throw the baby out with the bathwater. At the very point in time when consumers need most information to help them make the right food and supplement choices to help them offset largely preventable chronic diseases, we see the industry being gagged.

“Cowboys” are indeed a problem, and one well known to the American supplement industry. Says the head of the Council for Responsible Nutrition, the euphemistically named supplement trade association:

Fifteen years ago, our biggest threat was an over-reaching FDA….More recently, the problem has been an FDA that’s under funded and lacks the political will to do what it needs to do. And as a result today, many of the problems that burden the dietary supplement industry are ones that come from within the industry itself from that lack of oversight….Companies… intentionally – or inadvertently – put prescription drugs or anabolic steroids into their products and call them dietary supplements; products that just don’t do what they claim.  Also some companies practice economically motivated adulteration, passing off shoddy products as something more than they are … and ignore the new GMP requirements in hopes that they will fall under the radar screen.

Perhaps in response, the Boston Globe says we should repeal the 1994 law that deregulated dietary supplements and give the FDA some regulatory teeth.  Good idea.

Please forgive my endless repetition of this mantra: health claims are about marketing, not health.

Oh no! Bisphenol A again

Here’s a good reason why food manufacturers don’t want to test for harmful chemicals.  If you test, you might find something you don’t want to.

Consumer Reports did just that.  It tested a bunch of canned juices, soups, tuna, and green beans and found bisphenol A (BPA) in almost all of them — even the ones labeled organic or bisphenol A-free.

BPA, you may recall, is a chemical in polycarbonate plastics that acts as an endocrine disruptor.  How harmful is it?  Debate rages.  These new data will add to the debate.

CR says it found the highest levels of BPA in some samples of canned green beans and canned soups:

• Canned Del Monte Fresh Cut Green Beans Blue Lake had the highest amount of BPA for a single sample in Consumer Reports tests, with levels ranging from 35.9 parts per billon (ppb) to 191 ppb. Progresso Vegetable Soup BPA levels ranged from 67 to 134 ppb. Campbell’s Condensed Chicken Noodle Soup had BPA levels ranging from 54.5 to 102 ppb.

• Average amounts in tested products varied widely. In most items tested, such as canned corn, chili, tomato sauce, and corned beef, BPA levels ranged from trace amounts to about 32 ppb.

Because it was particularly concerned about BPA exposure for infants and young children, it tested samples of infant formula and apple juice.  It found:

• Similac liquid concentrate in a can averaged 9 ppb of BPA, but there was no measurable level in the powdered version.

• Nestlé Juicy Juice in a can averaged 9.7 ppb of BPA, but there were no measurable levels in the samples of the same product packaged in juice boxes.

Although the BPA in Nestlé Juicy Juice averaged 9 ppb, this was not so high, but children consume a lot of juice so this levels worries the testers.

While waiting for the experts to decide just how bad a problem BPA might be for adults and children, Consumer Reports recommends reducing the risk:

* Choose fresh food whenever possible.

* Consider alternatives to canned food, beverages, juices, and infant formula.

* Use glass containers when heating food in microwave ovens.

I would add to this: urge the FDA to finish up its scientific review right away.  It would be good to know more about just how harmful BPA is, and at what levels.

Update, November 4: I love the industry response to this report: “The use of bisphenol A (BPA) in can linings is both safe and vital for food protection.”

Update, November 9: Thanks to Jill Richardson of La Vida Locavore for telling me about her investigations into lobbying against restrictions on BPA (she also posted a summary as a comment here, but her site gives many more of the political details).  The plastics and related industries must be really worried.  They have reason to be worried.  There hasn’t been much reassuring news about BPA recently.

Meat arguments: health, climate, taxes

If only meat were just a food and not the flash point for concerns about health, climate change, and tax policy.  But it looms large in all such debates.

According to reports, meat is linked not only with a higher rate of cancer but also with type 2 diabetes.   Does this make logical sense?  It could, especially if meat eaters take in more calories and are fatter than non-meat eaters.

We’ve heard so much lately about how farm animals contribute to environmental problems and climate change, but Nicolette Hahn Niman writes in the New York Times of “the carnivore’s dilemma.”  It’s not the animals themselves that contribute to climate change, it’s the industrial methods of raising them that are the problem.  She ought to know.  She and Bill Niman run the free-range ranch in Bolinas, California highlighted in Time magazine last August.

On the other hand, Princeton professor and ethicist Peter Singer argues in the New York Daily News that meat is so bad for health and the environment that it ought to be taxed.

How to deal with all of this?  Push for more humanely and sustainably raised farm animal production, dont’ eat meat if you choose not to, and if you do eat meat, just don’t eat too much of it.

Update, November 4: I forgot to include Jonathan Safran Foer’s piece in the New York Times magazine on why he is against meat.

Pushback against food advocates

My latest column in the San Francisco Chronicle deals with an issue I discussed earlier on this blog: the ways in which agricultural and food interests are pushing back against advocates for a healthier and more sustainable food system.

Frank talk about food sometimes quashed

Marion Nestle, Sunday, November 1, 2009

Q: It must take courage to criticize the marketing practices of food companies. Doesn’t it get you into a lot of trouble?

A: Trouble? That depends on how you define it. Some pushback has to be expected as a normal consequence of advocating a food system that promotes better health for all and more sustainable agricultural production.

My latest experience with pushback occurred on World Food Day, Oct. 16. I had been invited by the U.S. Embassy in Rome to give the annual George McGovern lecture at the U.N. Food and Agriculture Organization. After my talk, our new ambassador to U.N. agencies in Rome, Ertharin Cousin, thanked me but told the audience that the opinions they had just heard were mine alone and did not represent those of the U.S. government.

What did I say that required a disclaimer? The point of my talk was to argue that international food issues such as hunger, obesity and food safety must be viewed as problems of society rather than personal choice.

As social problems, they are unlikely to be solvable by technical interventions such as functional foods, commercial weaning foods, irradiation or genetically modified foods. Instead, international food problems require social interventions that address underlying human needs for sustainability, social justice and democracy.

World insecurity

FAO had just released its 2009 report on the state of world food insecurity. Its date revealed how the economic crisis has caused the number of hungry people in the world to increase sharply. Some argue that genetic modification of crops is the only way to increase food productivity and reverse this trend. Whether food biotechnology really can fix world hunger is debatable, but one thing is clear: It is unlikely to create sustainability, social justice or democracy.

We know how to solve world hunger problems: promote breastfeeding, provide clean water and safe food, empower women, educate children, develop community food security, promote agricultural sustainability and ensure political stability. These strategies are social, not technological.

I ended my talk with praise for the Obamas’ leadership in promoting sustainable food production and initiating a new era in American agriculture.

Un-American? Under ordinary circumstances I would have shrugged off the ambassador’s remarks, but these are not ordinary times. I interpret her remarks as evidence that the food movement must be making real progress.

As further evidence, consider what happened to journalist and Berkeley professor Michael Pollan. His “Omnivore’s Dilemma” is high on the reading lists of many universities, yet twice this fall agricultural interests have attempted to force universities to cancel campus speaking invitations.

Pressure over Pollan

Washington State University had already bought 4,000 copies of “Omnivore’s Dilemma” for incoming freshman when a member of its Board of Regents, a wheat grower, objected to the way the book portrays industrial agriculture. The university canceled the reading program and Pollan’s lecture, saying it would cost too much at a time of budget crisis.

Bill Marler, a Seattle lawyer and WSU alumnus, called the university’s bluff by offering to pay the costs. Pollan’s book got distributed. He gave his talk. State agriculture did not collapse.

Much the same thing happened at Cal Poly San Luis Obispo. A local beef rancher, outraged that Pollan had been invited to speak unopposed, threatened to withdraw a promised $500,000 contribution. The rancher’s exchange of letters with Cal Poly’s president is available at links.sfgate.com/ZIMH, and well worth reading by anyone concerned about how industrial agriculture influences public policy.

Pollan offered the university a free lecture or panel with other speakers, but not both. The university chose the panel.

Although the rancher’s argument might appear to be about the value of presenting balanced views to students, universities are supposed to distinguish between academic and commercial interests. As university professors, Pollan and I base our opinions on our education, training, research and professional experience – not on how they might affect an industry. Our job is to teach students to read and think critically so they can form their own opinions about what we and others tell them.

Exerting influence

If our professorial opinions cannot be offered without public disclaimers and insistence on equal time for opposing views, I have to assume that what we are saying must be perceived as influential. If it indeed is influential, I expect even more pushback as the current food movement extends its reach and becomes stronger and more effective.

Trouble? Bring it on.

Italy’s new food label: “Mafia-free”

Thanks to Anulu Mass of the Global Post for telling me about the latest front-of-package foods labeling initiative, this one from Italy.  I’m just back from lecturing in Rome, Milan, and Vicenza, but didn’t get to Sicily which must be why I missed seeing Libera Terra labels on wine, olive oil, pasta, and tomato sauce.  Libera Terra labels guarantee that the foods were produced with no mob connections.  I’m so relieved.

Trick or treat?

Industry abandons Smart Choices!

The Connecticut Attorney General, Richard Blumenthal, announced yesterday that all eight food companies involved in the Smart Choices program have agreed to drop out pending his investigation and the FDA’s decision about front-of-package labeling.  Says Blumenthal:

Food manufacturers now realize that continued use of the logo would only mislead and compound consumer confusion. Other food labels richly deserve the same scrutiny — which we will give them with relish.

My investigation into Smart Choices, now supported by the FDA, continues to seek any scientific research or evidence behind a program that promotes mayonnaise, sugar-loaded cereal and ice cream as Smart Choices.

Many in the food and beverage industry have sugarcoated their labels — diverting and distracting consumers from nutrition truth, and pushing them toward obesity and disease. Self responsibility and good parenting are key to healthy lifestyles, but impossible when food manufacturers misguide them.

Our initiative should send a message to other food manufacturers that labeling must be completely truthful and accurate without hype or spin, especially when appealing to children. I am strongly encouraged by interest in our investigation by other attorneys general who can form a powerful coalition against misleading or deceptive food labeling.

Keep an eye out for what other city and state attorneys will be doing about food labels.   FDA: get busy!

Family doctors resign from AAFP over Coke partnership

Yesterday, 20 family physicians in Contra Costa County, California, ripped up their membership cards in the American Academy of Family Physicians in protest over the AAFP’s partnership with Coca-Cola.

coke_1

The director of the Contra Costa Department of Health Services, Dr. William Walker, announced that he was resigning his 25-year membership in AAFP.  In his statement, Dr. Walker said:

…I am appalled and ashamed of this partnership between Coca-Cola and the American Academy of Family Physicians. How can any organization that claims to promote public health join forces with a company that promotes products that put our children at risk for obesity, heart disease and early death.

…The AAFP is supposed to be an organization that works to protect the health of children not put them at risk. Their decision to take soda money is all the more unconscionable because, unlike doctors in the 40s, they well know the negative health impact of soda. There is no shortage of documentation that soda is a major contributor to our nation’s obesity epidemic.

…Let me be clear about something: as disappointed as I am with the American Academy of Family Physicians for being duped into thinking that Coca Cola wants to help promote health, the real problem here is our children are being put at risk.

Companies like Coca Cola are polluting our communities with deceptive advertising promoting products that put our children’s health at risk.

…as a family practice doctor and the Health Officer for Contra Costa, I do have a prescription for every parent, teacher, community leader and student:

Look beyond the glitzy advertising that makes you think pouring liquid containing sugar into your body is healthy. Read the label. Look at the ingredients. I’m not suggesting that you boycott sugared drinks, but please make an informed decision about what you are consuming.

I’m calling on every city and neighborhood in our County to fight back against the industry that pushes these harmful products. I ask the American Academy of Family Physicians to end this unhealthy partnership and to join us in leading this important campaign to take back the health of our residents and end the obesity epidemic.

Strong words, indeed.  I hope that the AAFP – and other health and nutrition organizations that might consider food industry partnerships – pay close attention to these words.

* The event was covered in the Contra Costa Times. The Health Department’s website includes the press release and also a video and podcast.

Addendum:

Dr. Wendel Brunner, PhD, MD, Director of Public Health in the Contra Costa Department of Health Services has given me permission to post excerpts from his letter to a representative of the California Association of Family Physicians who had asked for more information about the protest:

“The epidemic of obesity is the greatest public health and clinical medicine issue of our time, and will lead to untold disease, shortened life spans, and medical cost. That epidemic took off rapidly in the 80’s. While genes and personal choices do have an impact on obesity, only profound environmental changes could lead to such a rapid development of the epidemic, and it will only be stopped by policy development and environmental and norm change. We need to create an environment that supports people in making good choices for themselves and their families.

One of the best choices families can make is to pretty much eliminate sweetened beverages. And the soda industry doesn’t want that to happen, so they are looking for credible groups who will say that drinking soda is OK for your health. But you know all that already, which makes this even more frustrating.

I am an old county doctor, but I still believe that physicians have a responsibility to advocate for their patients and fight to protect their health, and to first of all, do no harm. I am truly gratified to see that our younger physicians in Contra Costa have those same values too. The responsibility of a physician to their patient is a sacred trust; physicians should never sell out their patients’ health and well-being for a price, not even one “in the mid six figures”.

The AAFP needs to change their policy and thereby begin to redeem themselves. In the process, they would educate the country and do something valuable for the nations health, as well as for their own integrity. If they do not, they will continue an unfortunately long and sordid tradition of professionals and their organizations forgetting their purpose and their ethics and putting their narrow organizational financial interest above the interest of the public that they serve. Resigning membership seems to be the most effective way for physicians to provide a wake-up call to the AAFP, and at this point is the best thing a physician could do to benefit the organization.We anticipate that there will be more resignations as this story develops.

Everything cannot be blamed on the environment or peer pressures or economic factors; patients do have a personal responsibility to make good choices for their health and the health of their families. But physicians have the personal responsibility to make good choices too, and so do the professionals who work for them.

The AAFP and the individuals in it made a bad choice. They now have the responsibility to fix it.”

San Francisco takes on Cocoa Krispies!

Now that the Smart Choices program is on hold, it’s time to take a look at what else is on food packages these days.  My current favorite example is the huge IMMUNITY banner across Kellogg’s Cocoa Krispies.

ImmunityI don’t know how you interpret this but my mind boggles at the very idea that eating Cocoa Krispies might protect kids against swine flu.

Apparently, the minds of the San Francisco attorney general’s staff are equally boggled.  They just sent a warning letter to Kellog:

“Specifically, the Immunity Claims may falsely suggest to parents that cereals like Cocoa Krispies are more healthy for their children than other breakfast foods that are not high in sugar and not highly processed.  The Immunity Claims  may also mislead parents into believing that serving this sugary cereal will actually boost their child’s immunity, leaving parents less likely to take more productive steps to protect their children’s health.”

The city attorneys are asking Kellogg to provide copies of all of the consumer and scientific research the company used to establish this claim, or else.  If they don’t get these documents, they will “seek an immediate termination or modification of the advertising claim….”

Good idea.  I can’t wait to see how Kellogg’s – ever at the leading edge of advertising claims – will respond.

But wait!  Shouldn’t the FDA be taking this on?
