Weekend reading: Industrial farm animal production

James Merchant and Robert Martin, eds. Public Health Impacts of Industrial Farm Animal Production.  Johns Hopkins University Press, 2024.

I served on the Pew Commission on Industrial Farm Animal Production with both authors about 15 years ago and was happy to do a blurb for their book.

This hard-hitting book defies meat industry pressure and obfuscation to document the devastating effects of its current production methods on the quality of air and water and on human health.  It doesn’t have to be this way.  Here’s a roadmap for a healthier and environmentally sustainable meat production system.

The book begins with an account of meat industry interference with the work of the Pew Commission and researchers investigating the health and polluting effects of CAFOs (confined animal feeding operations).

Our experience, and that of several of the authors of the 12 chapters in this book, have encountered considerable interference with their academic freedom as exerted directly by industrial agriculture or its pressure on academic administrators. Ensuring academic freedom, unbiased funding and unbiased research is critical to a sustainable environment and to protect the public’s health…. The pressure included industry harassment and intimidation of community residents, industry intrusion seeking to identify study subjects and research records, pressure applied to University administrators, and intimidation and litigation threats.

The multi-authored chapters document the extensive damage to health, the environment, and social justice caused by CAFOs, and recommend ways to deal with it.

Enforcing existing laws about air, water, soil, odor pollution, and animal welfare would be a good starting point.

The brave new world of cell-cultured—not just meat

Cell-culture isn’t just for beef anymore.  I’ve been collecting items…

FOIE GRAS:  ProVeg hails application for EU approval of cultivated foie gras: French company seeks approval for product made from cultivated duck cells.

EEL:  Cultivated eel that ‘melts in your mouth’? How Forsea mimics ‘tender, succulent’ texture of fish and seafood:  Eel meat is unlike any other: it is fatty, tender, and ‘almost melts in your mouth’, explains Roee Nir, co-founder and CEO of Forsea Foods. The start-up is working to mimic these attributes with stem cells in a lab…. Read more

COFFEE:  A cup of lab-grown Joe: researchers release proof of concept for cell-cultured coffee: Dr. Heiko Rischer and his team at VTT Technical Research of Finland published its cell-cultured coffee recipe, highlighting the opportunity to strengthen and reinforce the global coffee supply chain….

AND THE POLITICS, OF COURSE: Nebraska governor says no to lab-grown meat: If Gov. Jim Pillen has his way, Nebraska legislators will pass a law banning the sale of “lab-grown meat” — the industry prefers the term cultivated meat — during its next session. Florida and Alabama enacted state bans on the alternative meat this year, and Iowa has barred school districts and publicly funded colleges from buying the meat.

Brave new world: Tartrazine (an FDA-approved food color) makes mice transparent

I first read about this in a daily newsletter I subscribe to, Bakery and Snacks:   The Doritos effect: How tartrazine turns tissues temporarily transparent. When a study draws parallels with H.G. Wells’ The Invisible Man, you know it’s bound to be captivating. Could this scientific leap bring us closer to achieving a real-life version of Harry Potter’s invisibility cloak?… Read more

An ingredient in Doritos — tartrazine or Yellow 5 — is helping scientists see through the skin of mice. While they can’t see through human skin (it’s thicker and less permeable), this could be helpful in the future for early skin cancer detection. Imagine if it could replace a mammogram? On the other hand, Doritos food coloring is a chemical that the scientists said might not be totally harmless. (And to think so many people are eating it?) Read the Popular Science article about it. It’s fantastic.

Popular Science: The dye in Doritos can make mice transparent.  ‘It’s not magic, but it’s still very powerful.’

Because of a counterintuitive fundamental physics principle [selective absorption and scattering of light], Tartrazine, also known as Yellow 5, can temporarily turn biological tissue transparent to the naked eye, as described in a study published September 5 in the journal Science. 

The Science study: Achieving optical transparency in live animals with absorbing molecules.  Science.  Vol 385Issue 6713.  DOI: 10.1126/science.adm6869

We next sought to demonstrate the ability of absorbing molecules to achieve tissue transparency in the mouse abdomen. Specifically, when a tartrazine solution was topically applied to the abdominal skin of a live mouse under anesthesia and gently massaged on the skin (Fig. 1, G and H), the abdominal skin not only darkened in color but also became more transparent in the red window (fig. S8). This transparency effect can be readily visualized with the naked eye and does not require any specialized imaging equipment…The transparent abdomen allowed us to directly observe internal organs, including the liver, small intestine, cecum, and bladder (Fig. 1, I and J). Moreover, we could also discern their movements, such as peristalsis, as well as motions synchronized with the heartbeat and breathing (Movies 1 and 2). The achieved abdominal transparency can be reversed by rinsing and massaging the skin with water (fig. S8).

 

Tartrazine is FD&C  Yellow #5

Tartrazine is a synthetic food colorant classified as an azo dye. It is lemon yellow in color and water soluble. Tartrazine is approved for use as a food colorant in the EU, USA, Canada, and other parts of the world for use in food, cosmetics, and medications. Its use in foods includes dairy products, beverages, desserts, confectionary, spices, dressings, jellies and sauces…It is one of the most commonly used and best known food additives…Of the synthetic food dyes, tartrazine has been implicated most often as a cause of adverse reactions.

Here’s what CSPI says about it.

Yellow 5 can be found in many foods, including beverages, gelatin desserts, candy, and baked goods. It’s the second-most widely used coloring and sometimes causes allergy-like hypersensitivity reactions, primarily in aspirin-sensitive persons, and triggers hyperactivity in some children. It may be contaminated with such cancer-causing substances as benzidine and 4-aminobiphenyl (or chemicals that the body converts to those substances).

CSPI has filed a petition to

Ban the Use of Yellow 5 and Other Food Dyes, in the Interim to Require a Warning on Foods Containing These Dyes, to Correct the Information the Food and Drug Administration Gives to Consumers On the Impact of These Dyes on the Behavior of Some Children, and to Require Neurotoxicity Testing of New Food Additives and Food Colors.

And now here’s another reason not to use it, even though it doesn’t do this in people, apparently.  Our skin is too thick.

Addition

A reader points out that tartrazine is on the list of food dyes now banned in California.  Good idea.

UK nutrition experts have many ties to food companies: conflicted interests, anyone?

Here’s how I learned about this one: Unilever, Nestlé and Coca-Cola villainised for government scientist ties.  Mondelēz International, Tate & Lyle, Pepsico and a host of other global food and drink manufacturing majors face fresh scrutiny over their links to government-advising scientists…. Read more

Villainized?  Isn’t this just business as usual?

Not exactly.  An analysis in the BMJ (formerly British Medical Journal) says UK government’s nutrition advisers are paid by world’s largest food companies(see BMJ 2024;386:q1909).

The authors examined declared links between members of SACN (The UK Government’s Scientific Advisory Committee on Nutrition) and the food and drinks industry.

:

The study found

More than half of the experts on the UK government’s advisory panel on nutrition have links to the food industry…Campaigners say that these conflicts of interests at the heart of policy making are detrimental to public health. Others say that they reflect the lack of funding for nutrition research and that removing experts with industry links from SACN would “diminish” its expertise..

It also found

Six members of SACN are members of the American Society for Nutrition, which is funded by Mars, Mondelez, Nestlé, PepsiCo, and the Sugar Association, among others…SACN’s current work includes reviewing the evidence over ultraprocessed foods, artificial sweeteners, and plant based food and drink…Experts including van Tulleken and Percival say that SACN did not do enough to present the case for tougher regulation on ultraprocessed foods.

The usual excuses are

  • Independent experts are unavailable
  • Other research funding is not available
  • The funding has no influence

Much research, reviewed in my book Unsavory Truth: How the Food Industry Skews the Science of What We Eat, demonstrates these claims to be false.  Despite that research, recipients of industry largesse do not recognize the influence and typically deny it.

The more analyses like this one, the better.

Caveat

For a discussion of why disclosure is not sufficient (it causes “willy-waving”), see this in the BMJ.

Industry-funded opinion of the week: Against the benefits of plant-based diets

Two readers, Tara Kenny and Martin Caraher, sent this one:  Plant-based diets–impacts of consumption of little or no animal-source foods on human health.  by Alice V. Stanton  Front. Nutr., 17 September 2024. Volume 11 – 2024 | https://doi.org/10.3389/fnut.2024.1423925

The paper argues for the benefits of meat-based diets:

The protections provided by plant-based diets against NCDs [non-communicable diseases] appear to be more strongly associated with reduced intakes of calories and salt, and increased intakes of fruit, vegetables, nuts and whole grains, rather than with reduced intakes of ASFs [animal-source foods]. Any possible absolute adverse effects of red and processed meat consumption on NCDs are very small and uncertain…dietary guidelines should advise moderating excessive consumption, rather than substantially limiting or excluding ASFs from the human diet.

The author’s conflict-of-interest statement:

Alice Stanton was a part-time employee of Devenish Nutrition (2017–2023); and currently owns stock in Devenish Nutrition, an agri-technology company specializing in sustainable food solutions.

Comment

My readers point out that the author’s financial conflicts of interest are understated.  Devinish Nutrition is, in fact, a family businessThe company states it is “an innovator in animal nutrition by providing a wide range of products and services.”  It was acquired this year by EASY BIO a South Korean animal nutrition company.

Both readers also point out that Alice Stanton has pro-meat ideological conflicts of interest, but these concern me much less.  Everyone who does research has beliefs and hypotheses they want to test.  But not everyone stands to benefit financially from the outcome of their research or opinion, which is why full disclosure is so necessary.

PFAS in farmland: the next environmental frontier

For some reason, this did not get sent out yesterday and I do not want you to miss it.  It’s a really important story.

PFAS, Per- and polyfluoroalkyl substances, are synthesized chemicals resistant to water, grease, and heat, ubiquitous in consumer products, and widely dispersed in nature and in our bodies.

Their health effects are alarming: they are endocrine disruptors with adverse effects on the immune system, liver, birth weight, cancer.

Now they turn up in farmland, poisoning soil as well as people.

The New York Times did an investigation: Something’s Poisoning America’s Land. Farmers Fear ‘Forever’ Chemicals.

Known as “forever chemicals” because of their longevity, these toxic contaminants are now being detected, sometimes at high levels, on farmland across the country, including in Texas, Maine, Michigan, New York and Tennessee. In some cases the chemicals are suspected of sickening or killing livestock and are turning up in produce. Farmers are beginning to fear for their own health.

PFAS got on soil because of their presence in sewage sludge used as fertilizer.

PFAS in farmland is yet another reason to choose organics.  The Organic Standards specifically forbid use of sewage sludge as fertilizer.

The EPA is finally taking action on PFAS.  Better late than never.

How the food industry fights soda taxes

The Global Health Advocacy Incubator (GHAI) has issued this new report.  It’s well worth a look.

By now, soda taxes are well established to decrease consumption and raise revenues that can be used for social purposes.  As you might imagine, the soda industry does not like such taxes.  As the report explains,

Recently, Big Soda has adapted their [the cigarette industry’s] playbook and shifted their approach from outrightly opposing SB [sugary beverage] taxes to favoring weaker SB tax standards. This report highlights different actions and narratives employed by the industry and demonstrates how these strategies follow a global playbook, including:

  1. Proposing weaker taxes tailored to favor industry interests at the risk of public health.

2. Threatening and challenging governments that have passed an SB tax.

3.  Delegitimizing evidence to distort perceptions about SB taxes.

4.  Stigmatizing SB taxes through economic arguments.

5.  Taking advantage of and using vulnerable populations and environmental concerns to avoid the SB tax.

Under Strategy #5, for example, the report provides this information:

The report offers advice about how to counter industry measures by “(1) protecting the tax design to ensure it will have an optimal public health outcome, (2) safeguarding the policy decision-making process from undue influence and (3) leveraging opportunities for civil society to defend SB taxes.

For example, to safeguard policy decisions, it advises:

Avoid participating in public-private partnerships, especially those claiming to mitigate the “economic damages” of the SB tax through false solutions. This is the entry point for corporations to take a seat at the policy-making table and meddle with the design and implementation of the tax.

Soda taxes are up for renewal in Berkeley and are under consideration in Santa Cruz.  Stay tuned.

Bad news: US food insecurity getting worse, not better

The USDA has released its annual report on Household Food Security in the United States in 2023.

The news is not good.

What’s especially tragic is the reversal of the pandemic decline in food insecurity.

Pandemic income support and higher SNAP benefits did exactly what they were supposed to.  They reduced poverty.

Congress, in its infinite wisdom, stopped those benefits.

The results are entirely predictable.

These, alas, are political choices.

There’s an election coming up soon…
