Marketing works! A post stolen (OK, with permission) from ConscienHealth

I am a big fan and daily reader of ConscienHealth, mainly because its producer, Ted Kyle, invariably and consistently has something interesting to say about whatever he is writing about (obesity and health, usually).

I liked this one so much—it sounds just like something I would say—that I asked his permission to reproduce it.  He agreed.  Enjoy!

Controlled Study Shows How to Sell Less Easter Candy (if you click on the link, you can find the place to subscribe or comment)

Not every study in PLOS Medicine is thoroughly impressive, but this one is pure genius. Researchers at the University of Oxford have discovered that if grocers don’t promote Easter candy, they will sell less of it. But wait, there’s more. Those same researchers showed that promoting “healthy items” – like low fat potato chips – yields higher sales for those health-promoting snacks.

PLOS Academic Editor Jean Adams obviously recognized the genius of this research by Carmen Piernas, Georgina Harmer, and Susan Jebb. So she published an opinion paper alongside them, praising it. She says:

“Piernas and colleagues’ studies add to the accumulating evidence that restricting marketing on less healthy foods and encouraging marketing on healthier foods may be an effective way to support public health.”

But she also lamented the fact that implementation of tighter regulation of food marketing is slow to come. She calls it “a sad indictment of our collective inability to create a world that supports everyone to eat in the way they want to, rather than the way the marketers want for us.”

Easter Egg Hunts and a Trip to the Zoo

There’s a lot of great material in this trifecta of medical research and commentary. Adams tells us that supermarkets are out of control:

“The concentration of food marketing in grocery stores can feel particularly overwhelming with parents describing the ‘temptation’ as ‘like a trip to the zoo every week’ for their children.”

Seeing the brilliance of this research and commentary, headline writers got into the spirit. Our favorite:

Hiding Easter eggs better in supermarkets could rescue UK’s waistlines, Oxford study claims

Clearly, journalists understand how to capture the essence of serious public health science.

Actual Health Outcomes?

There’s just one tiny gap in this beautiful story. None of this research offers any evidence of healthier waistlines. It presumes that selling less Easter candy and more low-fat chips will cause waistlines to shrink.

Good luck with that. For decades now, food marketers in the U.S. have been selling us all kinds of food with claims that it’s healthy stuff to eat. Sales boomed and obesity kept rising. Onward and upward.

So count us skeptical that selling more low-fat chips and a little less Easter candy will put a dent in the UK problem with obesity.

ILSI by any other name…

I received a press release announcing a June conference to be held by the Institute for the Advancement of Food and Nutrition Sciences.

I had never heard of it.  It says it “is a non-profit organization that catalyzes science for the benefit of public health” and that it “drives, funds, and leads actionable research and elevates food safety and nutritional sciences—all with the ultimate goal of advancing public health.”

That seemed pleasant, if vague, but I was still puzzled.  Nothing on the Institute’s website helped.

This took some digging, but I soon found a news release announcing its formation in February 2021: Leading Scientists Launch Institute for the Advancement of Food and Nutrition Sciences to Promote Collaborative Research:

Today marks the establishment of the Institute for the Advancement of Food and Nutrition Sciences (IAFNS), a 501(c)(3) organization focused on catalyzing science for the benefit of public health.

Previously known as the International Life Sciences Institute, North America, IAFNS is building on a proud heritage with a focus on actionable science that promotes nutrition, food safety and public health.

Aha!  ILSI,  The classic industry front group.

ILSI, you may recall, was formed by Coca-Cola.

Within the last few years, lots of articles have appeared describing its lobbying efforts on behalf of the food industry.  Some of these were so blatant that Mars withdrew from in in 2018 and Coca-Cola withdrew in 2021.

I’ve written about ILSI often over the years.  See, for example, this post about IlSI’s effort in China.  Or see this article about scientific integrity (or the lack thereof).

Could all the bad press have anything to do with the name change?

A leopard cannot change its spots, alas.

No surprise: household food insecurity is increasing

The USDA tracks food insecurity in the United States.

The percentage closely tracks employment.  The 2008 recession caused an uptick, but then it declined.

Now it’s up again, thanks to the pandemic’s putting so many people out of work and causing food prices to rise.

The 2020 figure is nearly 15%, with 6.8% of children having especially low food security.

The Biden administration is working on this, as well it should.

Industry-funded study of the week: French fries are just as good for you as almonds

I like French fries as much as anyone but c’mon; they are hardly a health food.

The Alliance for Potato Research & Education sent me a press release about a new study demonstrating that “adding a daily 300-calorie serving of French fries to one’s typical diet every day for one month does not result in differential short-term weight gain or other biomarker changes associated with impaired blood sugar regulation compared to adding an isocaloric daily serving of almonds.”

The study: French-fried potatoes consumption and energy balance: a randomized controlled trial.  Daniel L Smith, Jr, Rebecca L Hanson, Stephanie L Dickinson, Xiwei Chen, Amy M Goss, John B Cleek, W Timothy Garvey, David B Allison.  The American Journal of Clinical Nutrition, nqac045, https://doi.org/10.1093/ajcn/nqac045

Purpose: “We completed an RCT [randomized controlled trial] testing whether increased daily potato consumption influences energy balance (specifically, fat mass (FM)) compared with calorie-matched almond consumption.”  Participants were given 300 calories a day in either fries (~3 oz) or almonds (~40).

Conclusion: There were no significant differences in FM [fat mass] or in glucoregulatory biomarkers after 30 days of potato consumption versus almonds. Results do not support a causal relationship between increased French fried potato consumption and the negative health outcomes studied.

Funding: This study was supported in part by a grant from the Alliance for Potato Research and Education (APRE) to DBA and DLS, by Core services through NIH grant awards P30DK056336 and P60DK079626 and the donation of study food items by J.R. Simplot Company.

Comment:  I’m not surprised by this result.   Biomarkers depend on everything you eat, not just one food.

The purpose of this study was to take away any guilt you might feel about eating French fries.   The potato alliance got the result it wanted.

Weekend reading (in French): Mange et Tais-Toi

Serge Hercberg.  Mange et tais-toi: Un nutritionniste face au lobby agroalimentaire. HumenSciences 2022. 285 pages.


The author sent me a copy of this book in optimistic overestimation of my ability to read French.

Well, I can translate the title at least and it’s a great one: Eat and Shut Up: A Nutritionist Faces (Confronts?) the Agribusiness Lobby

But I’d really appreciate an English translation of the book, even though articles in English are readily available.

With that acknowledged, Hercberg is well known for his development and promotion of Nutri-Score, a front-of-package rating system used in Europe.

The letter grades are assigned on the basis of a composite score of healthy (vitamins, fiber, etc) and unhealthy (salt, sugar, etc) components.  They range from from A excellent to E best to avoid.

You can easily imagine that producers of products with low grades dislike this system.  Hercberg’s book, a memoir of his early career, describes his later work in the context of food industry efforts to block use of Nutri-Score.

While I’m on the topic, here are a few recent articles.

Food waste: much talk, some action

I’ve been collecting items on food waste.  Here are four recent ones.

I.  EPA: From Farm to Kitchen: The Environmental Impacts of Food Waste.   The Infographic Summary:

II.  WWF: Driven to Waste: The Global Impact of Food Loss and Waste on Farms.

Driven to Waste: Global Food Loss on Farms, a new report from WWF and Tesco, reveals an estimated 2.5 billion tonnes of food goes uneaten around the world each year. That is an increase of approximately 1.2 billion tonnes on the established estimates of 1.3 billion tonnes wasted each year. These new estimates indicate that of all the food grown, approximately 40 per cent goes uneaten, which is higher than the previously estimated figure of 33 per cent.

III.  Washington State Department of Ecology: Use Food Well Washington: A roadmap to a more resilient food system through food waste reduction].

Food waste is one of the greatest challenges of our time, with significant environmental, social, and economic impacts. Thankfully, our research shows the potential benefits to addressing food waste in Washington are just as enormous (Fig. 1).
Our calculations indicate Washington generates more than one million tons of food waste annually, with a large portion (about 35 percent) being edible food going into landfills.

IV.  How are food manufacturers tackling waste management?  As 2022 gets underway, waste management has moved from arguably to inarguably never more important…. Read more

International food ingredients: endangered shark in Singapore pet food

Pet food, as I am fond of repeating, is an essential part of the human food supply because it uses the waste from human food production.

Also, whatever is happening with pet food indicates what could well be happening with human food.

That’s why I was fascinated to read this account in Pet Food Industry of finding DNA from endangered sharks in any number of pet food brands.

Researchers identified shark genetic material in cat foods purchased in Singapore, including Fancy Feast, Sheba, Whiskas, Kit Cat and Aixia Yaizu. The scientists suggested that endangered silky sharks and other species ended up in pet foods. However, the study’s authors couldn’t determine the route by which the shark meat made its way into the pet food supply chain. Likewise, they didn’t have easy solutions for how pet food companies could avoid inadvertently allowing endangered sharks into their products.

The evidence comes from a report of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Pet Food Industry further explains:

The silky shark (Carcharhinus falciformis), listed as CITES Appendix II, was the second most frequently encountered species in the pet foods. Silky sharks face tremendous hunting pressure for their fins. The researchers speculated that the presence of the silky sharks may reflect the use of the rest of their carcasses in pet food.

Blue sharks, Prionace glauca, were the most common species in the samples. Blue sharks are not listed in CITES or classified as threatened by the IUCN, but scientists believe it is being overfished and needs regulation.

None of the pet foods’ ingredient decks mentioned sharks. Terms such as “ocean fish,” “white fish” and “white bait” appeared though.

I wrote about the pet food supply chain (particularly as related to melamine contamination) in Pet Food Politics and, with Mal Nesheim, in Feed Your Pet Right.  

The point: If we don’t want to encourage destruction of endangered species, we ought to be checking cans of tuna for people while we are at it.

Industry-funded trial with surprising results

Yesterday I reported about the COSMOS clinical trial demonstrating reductions in mortality among people taking cocoa flavanol supplements.

That trial had another arm: multivitamin supplements.

The study: Multivitamins in the Prevention of Cancer and Cardiovascular Disease: The COSMOS Randomized Clinical Trial.  Sesso HD et al.  The American Journal of Clinical Nutrition, nqac056, https://doi.org/10.1093/ajcn/nqac056

Conclusion: The supplements did not reduce cardiovascular disease, cancer, or all-cause mortality in older men and women.

Funding: The COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is supported by an investigator-initiated grant from Mars Edge, a segment of Mars dedicated to nutrition research and products, which included infrastructure support and the donation of study pills and packaging. Pfizer Consumer Healthcare (now part of GSK Consumer Healthcare) provided support through the partial provision of study pills and packaging.

Conflicts of interest: Drs. Sesso and Manson reported receiving investigatorinitiated grants from Mars Edge, a segment of Mars Incorporated dedicated to nutrition research and products, for infrastructure support and donation of COSMOS study pills and packaging,
Pfizer Consumer Healthcare (now part of GSK Consumer Healthcare) for donation of COSMOS study pills and packaging during the conduct of the study. Dr. Sesso additionally reported receiving investigator-initiated grants from Pure Encapsulations and Pfizer Inc. and honoraria
and/or travel for lectures from the Council for Responsible Nutrition, BASF, NIH, and American Society of Nutrition during the conduct of the study. No other authors reported any conflicts of interest.

Comment: Pfizer, of course, makes Centrum multivitamin supplements aimed at older adults.

I was surprised by this part of the trial because previous studies have also shown no consistently beneficial effect of supplementation of individual vitamins or multivitamins on disease risk.  Pfizer must have hoped to find benefits for Centrum.  This is a rare industry-supported study that showed no benefits and is, therefore, worth attention.
