This Week’s Report #3: Food Foundation’s State of the UK’s Food Industry

From the report’s introduction

THE UK’S FOOD SYSTEM ISN’T WORKING. It is unsustainable, unhealthy, and unfair. Deep rooted power imbalances mean that profits and power are concentrated in the middle of the food chain, leaving farmers and citizens feeling the squeeze. Among the poorest fifth of the population, households with children would need to spend 70% of their disposable income on food just to afford the government’s recommended healthy diet….

Diet, overweight and obesity are now the biggest risk factor for preventable death and disability in the UK…growing numbers of farmers and growers are struggling to make a living, with 61% of British farmers saying they are likely to give up their farm in the next 18 months….This is arguably an example of market failure – a predictable outcome of a food system where the governing rules mean there is currently little incentive for companies to sell healthy and sustainable foods.

It makes these points with  data.

I like this one too.

Happy turkey day to all!

Well, only a little.

First, what this dinner is going to cost you: less than last year but more than before the pandemic.

And how about some agricultural statistics for turkeys?

And some key facts:

  • The rise and fall of turkey production in the U.S.: Since 1960, per capita turkey production rose sharply and peaked in 1996 at 26.8 pounds per person. However, in 2022, annual production had dropped to just 20 pounds per person—a decline of approximately 25%.
  • Rising prices and shifting consumer demand: Health concerns and changing dietary preferences play a significant role, with more Americans choosing plant-based diets and reducing meat consumption. Rising turkey prices, which increased from $0.80 per pound in 2018 to $1.40 per pound in 2023, also impact consumption.
  • Larger birds soften the decline: The average size of turkeys raised in the U.S. has nearly doubled since the 1960s—averaging 32 pounds per bird compared to around 18 pounds in the 1960s. This trend has helped maintain relatively high production levels even as the total number of turkeys raised has declined (a peak of approximately 303 million birds annually in 1996, but an estimated 218 million birds in 2023).

Aren’t you happy to know all this?

Enjoy your dinner!

This Week’s Report #2: WHO/FAO

What are healthy diets? Joint statement by the Food and Agriculture Organization of the United Nations and the World Health Organization

What this is about:

Healthy diets promote health, growth and development, support active lifestyles, prevent nutrient deficiencies and excesses, communicable and noncommunicable diseases, foodborne diseases and promote wellbeing. The exact make-up of a diet will vary depending on individual characteristics, preferences and beliefs, cultural context, locally available foods and dietary customs. However, the basic principles of what constitutes healthy diets remain the same.

The guiding principles: Adequate, Balanced, Moderate, Diverse.

Here’s what they mean by Balance:

The actual guidelines are discussed under the Moderate principle.

  • Sodium: restrict to 2 grams/d (5 g table salt)
  • Sugars: restrict to 10% or less of daily calories.
  • Saturated fat: restrict to 10% of calories, with no more than 1% from trans fat

FAO and WHO duck making a clear statement about the next two issues, although their implications are clear.

  • Red and processed meat: even low levels may have negative health consequences
  • Ultra-processed foods: these have negative health consequences

I wish they had stated these recommendations more clearly.  Yes they are controversial with big industries lobbying against any suggestion to eat less of these foods, but these agencies, or at least WHO, should put public health first.

I recognize that these agencies have constituencies of nearly 200 countries, many with strong meat and ultra-processed food industries.  I also recognize that the agencies have no power other than leadership to get any of those countries to do anything.

They at least stated what they thought.  It’s up to country governments to take action.  I hope they do.

This week’s report #1: FAO’s State of Food and Ag, 2024

It’s a slow-news holiday week so I’m going to use it to catch up on reports.  The first:

FAO: The State of Food and Agriculture 2024: Value-Driven Transformation of Agrifood Systems

FAO uses true cost accounting (TCA) to analyze global food systems.

  •  By improving on the hidden costs quantified in The State of Food and Agriculture 2023, this report unpacks the health hidden costs associated with unhealthy dietary patterns linked to an increased risk of non-communicable diseases (NCDs).
  •  Case studies show how targeted TCA assessments conducted across multiple agrifood systems categories provide more nuanced insights into the requisite agrifood systems transformation and potential actions moving forward.

Here is an example of the kinds of analyses presented here.

And here are the resources:

Industry-funded study of the week: plant-based meat alternatives

Plant-Based Meat Analogs and Their Effects on Cardiometabolic Health: An 8-Week Randomized Controlled Trial Comparing Plant-Based Meat Analogs With Their Corresponding Animal-Based Foods. Toh DWK, Fu AS, Mehta KA, Lam NYL, Haldar S, Henry CJ. Am J Clin Nutr. 2024 Jun;119(6):1405-1416. doi: 10.1016/j.ajcnut.2024.04.006. Epub 2024 Apr 8.

Erratum in: Am J Clin Nutr. 2024 Aug;120(2):459. doi: 10.1016/j.ajcnut.2024.06.012.

This study compared effects on cardiometabolic health among people eating meat or plan-based alternatives for 8 weeks.

Conclusion: An 8-wk PBMA (plant-based) diet did not show widespread cardiometabolic health benefits compared with a corresponding meat based diet.

Funding: This study was supported by Pinduoduo Incorporated (HongKong Walnut Street Limited). Pinduoduo Incorporated had no role in study design, study conduct, laboratory analyses, data collection, management and interpretation or the writing, reviewing and approval of the manuscript.

Comment

This study was sent to me by a reader, who viewed it as a rare example of an industry-funded study with results unfavorable to the sponsor’s interests.  He thought the “Walnut” in the company’s name indicated a plant-based bias.

I wasn’t so sure and wondered what Pinduoduo did, exactly.

According to Wikipedia, “Pinduoduo Inc. (Chinese拼多多Pinyin: Pīn duōduō) is a Chinese online retailer with a focus on the traditional agriculture industry. The business is the largest product of PDD Holdings, which also owns the online marketplace Temu.”

But it gets even better.  The American Journal of Clinical Nutrition published a correction to the paper:

The original funding statement was insufficiently elaborated and has been revised for greater clarity: Christiani Jeyakumar Henry [the senior investigator on this study] reports partial financial support provided by Pinduoduo Incorporated (HongKong Walnut Street Limited) which is an agricultural research firm.

This, then, is a standard example of an industry-funded—and conducted—study producing just the results wanted.  Another example of marketing research, alas.

Weekend reading: Real Food, Real Facts

Charlotte Bilekoff.  Real Food, Real Facts: Processed Food and the Politics of Knowledge.  University of California Press, 2024.  267 pages.

Food processing is a big issue these days (witness RFK Jr’s pledge to get ultra-processed foods out of school meals) and I was interested to see what food studies scholar Charlotte Biltekoff had to say about it.

Her thesis: When people say they want to eat “real food” rather than highly processed food, the food industry responds with “real facts,” science-based discussions of the benefits of food processing (“food scientism”).

The industry’s response is based on the idea that if you could only correct public ignorance and misperceptions, you could sell your products more easily.

But public concerns are about politics, not science.  And food scientism is a form of antipolitics.

She cites as an example, the FDA’s ongoing inability to define the term “natural.”

Concerned about health, sustainability, and risk and wanting change in the food system, the public sought to act on its values and aspirations in the marketplace.  Narrowly reframing those concerns as demands that could be met through product reformulations and new approaches to marketing—but without serious, systemic engagement with the broader issues they reflected—the food industry produced products that appeared to be more natural, less processed, and therefore better…articles in the industry press and comments to the FDA show that many perceived the consumers of “real food” as irrational and misinformed.  Seen through the lens of food scientism of the Real Facts frame, consumer perceptions of processing and what “natural” meant, or should mean, were further proof that the public lacked the skills and understanding to meaningfully participate in the regulatory processess, let alone act as knowledgeable participants in the governance of technology and the shaping of the food system. (p. 143)

What Biltekoff has done here is to translate the classic two-culture risk communication problem to food.

Her book made me go back and look at what I wrote about the two-culture problem in Safe Food: The Politics of Food Safety.  The book contrasts the differing perceptions of industry and the public about the potential harm of microbial foodborne illness versus GMOs.

These differences in approaching questions of risk were understood long before anyone invented the techniques for genetically modifying foods. In 1959, for example, the scientist and writer C. P. Snow characterized the ways in which people trained in science tend to think about the world—as opposed to those without such training—as representing two distinct cultures separated from one another by a “gulf of mutual incomprehension” [1]. Much more recently, the anthropologist Clifford Geertz wrote, “The ways in which we try to understand and deal with the physical world and those in which we try to understand and deal with the social one are not altogether the same. The methods of research, the aims of inquiry, and the standards of judgment all differ, and nothing but confusion, scorn, and accusation—relativism! Platonism! reductionism! verbalism!—results from failing to see this” [2].  [1. Snow CP. Two Cultures and the Scientific Revolution: The Rede Lecture. London: Cambridge University Press, 1959; 2. Geertz C. Empowering Aristotle (book review). Science 2001;293:53].

Science-based approaches to food safety, I pointed out, count cases and estimate costs, whereas what I called “value-based” approaches, are about feelings of dread and outrage.

Biltekoff’s analysis applies the two-culture framework to public responses to food processing and to the ways the food industry deals with those responses.

Her analysis explains much about the current pushback against the concept of ultra-processed foods from the food industry and some nutritionists.  If you want to understand why the Dietary Guidelines Advisory Committee has chosen not to recommend reducing intake of ulra-processed foods, read this book.

And, amazingly, the book is available as open source.  Read the book online here.

Benefits of the dietary guidelines: resources

DietaryGuidelines.gov provides handouts on Food Sources of Select Nutrients.

Alas, calories are not among these handouts, even though 75% of American adults are now considered overweight or obese.

These are meant for nutrition professionals but are fun to see if you want to see what they get.

The page lists lots of other resources.

Will these help you make healhier dietary choices?

Nutrients are not the problem; calories are the problem.

To do something about them, we need a healthier food environment.

I wish the USDA would give that as much attention as it gives nutrients.

Can Robert F. Kennedy, Jr influence the Dietary Guidelines? Most definitely, yes.

The 2025-2030 Dietary Guidelines Advisory Committee (DGAC) report is well underway.   The committee either has submitted or is about to submit its report to HHS and USDA;.  The report has not yet been posted, but presumably will be posted soon.

But understand: the scientific advisory committee is just that: advisory.

The agencies, HHS and USDA, are responsible for writing the actual guidelines.  They choose an internal committee to do that work.  That new committee can pick, choose, add, or subtract from the advisory committee’s report.

So yes, the new Secretaries of HHS and USDA can have a lot of input (and veto power) into the new guidelines.

As I’m fond of repeating, the guidelines process was quite different when I was on the DGAC in 1995.  Then, our committee chose the research topics, reviewed the research, wrote the advisory committee report, and wrote the actual dietary guidelines.  The agencies made only minor tweakings.

The agencies have written the guidelines since 2005, making the process much more subject to politics.

The DGAC, for example, viewed the evidence on ultra-processed foods as too limited to take a stand, yet RFK, Jr says ultra-processed foods are killing us.

The development of the 2025-2030 guidelines will be most interesting to watch.  Stay tuned.
