Industry-funded study of the week: widespread nutrient deficiencies Down Under

I saw this in DairyReporter, a newsletter I subscribe to.

Multi-nutrient inadequacies in ANZ linked to diet-related disease calls for food-based interventions – a2 Milk-funded study.  A study has found multi-nutrient inadequacies within the Australia and New Zealand (ANZ) populations, including nutrients associated with diet-related disease, highlighting the need for public policies and food-based recommendations to promote intake….

A2-milk again?  The last time I wrote about it, I titled my comments, A2 milk: still making claims based on industry-funded research.

Well, here’s the latest .

The study: Priority nutrients to address malnutrition and diet-related diseases in Australia and New Zealand.  Front. Nutr., 12 March 2024. Volume 11 – 2024 | https://doi.org/10.3389/fnut.2024.1370550. 

The alarming results: 22 of 31 essential nutrients are consumed by people in Australia and New Zealand below recommended levels, particularly vitamin D, calcium, omega-3 fatty acids, magnesium, folate, dietary fibre.

Funding:  “The author(s) declare financial support was received for the research, authorship, and/or publication of this article. This project has been funded by a research grant from The a2 Milk Company. The funding body had no contribution to the methodology, data analysis, drafting of the manuscript, nor interpretation of the findings.”

Comment: The methods depend on reported intake as compared to nutritional standards.  The study does not attempt to correlate its findings with clinical signs of nutrient deficiency in the study populations studied.  I doubt there were any.  Vitamin deficiency symptoms are rarely seen in well-fed populations.  Instead, the principal diet-related diseases are those related to eating too much food—obesity and its consequences—just as they are in the U.S.

Why would the A2-Milk Company care about this topic?  My guess: so you will want to remedy this situation by drinking A2-milk.

A reminder: A2-milk, according to its producer, “comes from cows that produce only the natural A2 protein and no A1.  It is easier on digestion and may help some avoid stomach discomfort.”  Whatever.

Industry-funded study of the week: Pork

A reader, Tara Kenny, sent me this one.  She wrote that she had seen a chart from this paper posted on X (Twitter) “showing  how pork, chicken, eggs, fish and turkey are almost the same as beans and nuts in terms of mean GHGs/50g of protein so I figured this paper would have likely have some conflicts of interests…It does.”

I went right to it.

  • The paper: Perspective: The Place of Pork Meat in Sustainable Healthy Diets. Advances in Nutrition.  Adam Drewnowski.  Advances in Nutrition.  Volume 15, Issue 5, May 2024, 100213.
  • Rationale. “The present analyses explore the place of pork in sustainable healthy diets worldwide, given the need for high-quality protein and the predictable patterns of global food demand.”
  • Method: “This Perspective article aims to assess the place of fresh pork in the global sustainability framework, drawing on data from United States sources and from international agencies. The present goal was to examine the sustainability of pork as a source of meat protein, considering nutrition, affordability, environmental impact, and future food demand.”
  • Conflict of interest: “AD is the original developer of the Naturally Nutrient Rich (NNR) and the Nutrient Rich Food (NRF) nutrient profiling models and a member of scientific advisory panels for The National Pork Board, Nestlé, FrieslandCampina, BEL, and Carbohydrate Quality Panel supported by Potatoes USA and has worked with Ajinomoto, FoodMinds, KraftHeinz, Nutrition Impact LLC, Nutrition Institute, PepsiCo, and Samsung on quantitative ways to assess nutrient density of foods.”
  • Funding: “Analyses of publicly available USDA, FAO, and World Bank data were supported by the National Pork Board. The funders were not involved in the development of databases, analytical models, data analysis or interpretation, manuscript preparation or the decision to submit the manuscript for publication.”

Comment: Reducing greenhouse gas emissions produced by agriculture is an important goal.  Most researchers think industrialized countries should produce less meat (particularly beef) as a necessary first step.  This analysis suggests we stop worrying about the effects of pork on climate change (never mind the effects of industrial pork production on air, land, and water within smelling distance). This article, by my old friend and colleague Adam Drewnowski, is an excellent overview of pork nutrition.  But why do it?  The title alone raises the question, “Who paid for this?”

Uh oh. Bulk organic walnuts associated with toxic E. coli

I learned about this one from Bill Marler’s blog: This is Nuts – California and Washington E. coli Outbreak linked to Gibson Farms Walnuts 

This refers to the CDC announcement: E. coli outbreak linked to organic walnuts

The CDC issued a warning: CDC warns of E. coli outbreak linked to organic walnuts sold in bulk

The FDA has its own investigation: Outbreak Investigation of E. coli O157:H7: Bulk Organic Walnuts (April 2024): Do not eat, sell, or serve recalled organic walnuts sold in bulk bins at natural food and co-op retailers in multiple states. FDA’s investigation is ongoing.

The CDC points out:

  • Almost all sick people purchased organic walnuts from bulk bins in food co-ops or natural food stores in California and Washington.
  • FDA determined that Gibson Farms, Inc supplied these walnuts and Gibson Farms, Inc has recalled these products.: These walnuts have expiration dates between May 21, 2025, and June 7, 2025.
  • FDA has a list of stores that may have received these walnuts.

Comment:  All toxic E. coli outbreaks are troubling because the illnesses are so serious and all are preventable if producers were doing what they were supposed to be doing.  But walnuts?  My first question is how could walnuts, firmly encased in shells, get contaminated with animal fecal wastes, the usual source of this strain of E. coli.  This reminds me of the Odwalla juice E. coli problems; the company had harvested apples that had fallen on the ground. Did Gibson harvest walnuts off the ground?  Whatever it did, the company should have been following a food safety plan mandated by the Food Safety Modernization Act, which requires prevention controls and testing to make sure things like this donn’t happen.

Are non-organic walnuts harvested any differently from organic walnuts.   Here’s what one producer says.

The nuts are removed from the tree using a mechanical shaker, a machine that grasps the trunk and shakes the whole tree. The nuts drop to the ground, are then swept into windrows and picked up with harvest machinery. This operation is completed quickly to reduce the time nuts remain on the ground.

Uh oh indeed.  I hope this incident causes some changes in this procedure.

In the meantime, Marler has more to do.

Weekend reading: The Good Eater

Nina Guilbeault.  The Good Eater: A Vegan’s Search for the Future of Food.  Bloomsbury, 2024.

I did a back-cover blurb for this book:

The Good Eater is a vegan sociologist’s remarkably open-minded exploration of the historical, ethical, health, environmental, and social justice implications of not eating meat.  Guilbeault’s extensive research and interviews get right into the tough questions about this movement, leaving us free to choose for ourselves whether to eat this way.

Guilbeault has followed vegan dietary practices (no animal products) for a long time but was troubled by the self-righteousness and proselytizing of many vegans.  As a trained sociologist, she set out to investigate the origins, practices, and effects of vegan diets, through reading but also through interviews with what seems like everyone having anything to do with animal welfare and plant-forward diets.  The result is an exceptionally broad look at the who’s who of veganism, from historical figures to contemporary entrepreneurs and chefs.  The book is well written, rational, and not at all uncritical.

Here’s are a couple of excerpts:

Projections show that to avert environmental disaster by 2050 we need to reduce our meat consumption by at least a third, and by half in North America and Europe…But many people still eat eggs for breakfast and yogurt as a snack, put dairy milk in their coffee, add a slice of ham to their sandwich for lunch, and choose a piece of meat or fish for dinner, all in one day.  A reduction from that daily menu to a couple of eggs and a small piece of meat or fish once a week seems like a hefty drop, yet that is how humanity has eaten for most of our natural history.  (pp 284-285)

I can understand why, for many people, a vegan lifestyle seems unappealing, overwhelming, or even downright offensive.  As we know, meat has played a key part in our cultural and evolutionary history, and habits are notoriously difficult to break.  Veganism requires a shift in identity as well as the embrace of a social category still on the fringe….This is partly because being vegan in a non-vegan world is hard, but also because the vegan movement places an emphasis on moral perfection.  Yet…long-lasting, sustainable change doesn’t come from a place of shame, judgment, and guilt.  It comes from a place of joy and a sense of belonging.  (p 290)

Weekend reading: Compassionate Eating

Tracey Harris and Terry Gibbs. Food in a Just World: Compassionate Eating in a Time of Climate Change. Polity Books, 2024. 

I blurbed it:

Food in a Just World is an up-to-the-minute introduction to issues of class, race, and gender—and species—in what we eat, as well as to how larger issues of economics and capitalism affect workers in the meat industry.  Whether you eat meat or not, the book convincingly argues that these issues demand serious attention.

Here’s what the publisher says about it:

Food in a Just World examines the violence, social breakdown, and environmental consequences of our global system of food production, distribution, and consumption. From animals in industrialized farming – but also those reared in supposedly higher-welfare practices – to low-wage essential workers, and from populations being marketed unhealthy diets to the natural ecosystems suffering daily degradation, each step of the process is built on some form of exploitation. While highlighting the broken system’s continuities from European colonialism to contemporary globalization, the authors argue that the seeds of resilience, resistance, and inclusive manifestations of cultural resurgence are already being reflected in the day-to-day actions taking place in communities around the world. Emphasizing the need for urgent change, the book looks at how genuine democracy would give individuals and communities meaningful control over the decisions that impact their lives when seeking to secure this most basic human need humanely.

Cultured meat: of great interest, still not on market

Cell-Based or Cultured Meat continues to generate predictions, positive (new products, new approvals, growth) and negative (doom, bans).

Current status: The FDA and USDA have approved sales of cell-cultured chicken but the only place selling it is Bar Crenn in San Francisco (where I have not been).

While waiting for it to get scaled up (if this ever will be possible), here are a few items I’ve collected recently.

Weekend reading: Food system analysis

I was interested to see this report and the academic analysis on which it is based—both from the Food Systems Countdown Initiative.

The academic analysis is extremely complicated and difficult to get through.  This initiative is highly ambitious.  It developed a set of 50 (!) indicators and “holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals.”

The 50 indicators fall under five themes: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience.

The analysis applies these themes and indicators to countries by income level and finds none of them to be on track to meet Sustainable Development Goals.

I can understand why they produced a report based on the analysis: it is easier to understand (although still extremely complicated).

For one thing, it defines Food Systems; By definition, food systems are complicated.

Food systems are all the people, places, and practices that contribute to the production, capture or harvest, processing, distribution, retail, consumption, and disposal of food.

For another, it presents data on compliance with indicators in more comprehensible ways, for example, these two indicators from the Diet theme.

As the report makes clear, this use of indicators has useful functions:

  • Global monitoring of food systems
  • Tracking UN Food System Summit commitments
  • Development of national monitoring systems

This initiative reminds me a lot of the decades-long US Healthy People process—currently 359 (!) health objectives to be achieved by 2030—with no responsibility assigned for making sure they are achieved (which they mostly have not been, unsurprisingly),

Initiatives like these are great about identifying gaps.  What they can’t do is hold governments accountable.  They are supposed to inspire advocacy; to the extent they do, they might have some chance at stimulating progress.

As you can tell from my insertion of parenthetical explamation points, I think there are too many things to keep track of.

But then, I’m a lumper; this is a splitting initiative.

Both have their uses, but I want to see priorities for action.

Kratom: a primer on its politics

I see stores selling Kratom all over my downtown Manhattan neighborhood and am curious about it (no, I have not tried it, nor do I intend to).

I took a look at the websitesof the American Kratom Association (AKA) and the FDA’s Kratom page.

The AKA describes itself as “a consumer-based, nonprofit organization, focuses on setting the record straight about kratom and gives a voice to those who are suffering by protecting their rights to possess and consume safe and natural kratom.” It says:

Natural kratom comes from the mitragyna speciosa, a tropical evergreen tree in the coffee family native to Southeast Asia…Naturally occurring Kratom is a safe herbal supplement that behaves as a partial mu-opioid receptor agonist and is used for pain management, energy, even depression and anxiety that are common among Americans. Kratom contains no opiates, but it does bind to the same receptor sites in the brain. Chocolate, coffee, exercise and even human breast milk hit these receptor sites in a similar fashion.

Thus, according to the AKA, Kratom is something like chocolate or breast milk.

The FDA, in fact, defines Kratom in much the same way:

Kratom is a tropical tree (Mitragyna speciosa) that is native to Southeast Asia…Kratom is often used to self-treat conditions such as pain, coughing, diarrhea, anxiety and depression, opioid use disorder, and opioid withdrawal. An estimated 1.7 million Americans aged 12 and older used kratom in 2021, according to the Substance Abuse and Mental Health Services Administration’s National Survey on Drug Use and Health.

So far so good.

But the AKA is calling on the FDA to regulate Kratom.  This may sound highly responsible, but the AKA is doing this because the FDA refuses to have anything to do with this product and warns against its use.

The FDA says:

  • Kratom is not an approved drug: “There are no drug products containing kratom or its two main chemical components that are legally on the market in the U.S.
  • Kratom is not an approved dietary supplement: “FDA has concluded from available information, including scientific data, that kratom is a new dietary ingredient for which there is inadequate information to provide reasonable assurance that such ingredient does not present a significant or unreasonable risk of illness or injury.’
  • Kratom is not an approved food additive: “FDA has determined that kratom, when added to food, is an unsafe food additive.”
  • Therefore, kratom is not lawfully marketed in the U.S. as a drug product, a dietary supplement, or a food additive in conventional food.

The FDA’s Q and A:

  • What can happen if a person uses kratom?  FDA has warned consumers not to use kratom because of the risk of serious adverse events, including liver toxicity, seizures, and substance use disorder (SUD). In rare cases, deaths have been associated with kratom use…However, in these cases, kratom was usually used in combination with other drugs, and the contribution of kratom in the deaths is unclear.
  • How is FDA protecting the public from the risks of kratom?   FDA has also taken steps to limit the availability of unlawful kratom products in the U.S. We will continue to work with our federal partners to warn the public about risks associated with use of kratom.

The AKA says its mission is to

  • Support Consumers. The FDA does everything it can do to interfere with the right of consumers to make informed choices about products they use for their health and well being, and their war on kratom includes distributing disinformation on kratom that materially misleads consumers and policy makers. Our goal is to change that.
  • Educate. Kratom is a natural plant that helps consumers improve their health and well being for centuries. Our goal is to educate all Americans with the truth about kratom — from potential consumers to regulators and everyone in between.
  • Speaking the Truth on Kratom. We represent millions of Americans that each have a story to tell. The FDA wants to drown out the individual voices, but we will raise those voices and together we will be heard across America.
  • Global Awareness. Anti-kratom detractors are trying to expand kratom bans across the world. We hope to demonstrate responsible use and the health benefits of kratom will convince other countries to responsibly regulate kratom, not ban it.
  • Protect Natural Resources. Kratom is a precious natural resource that is an important part of our global ecosystem. We support and advocate for sustainable harvesting techniques and reforestation protecting existing kratom forests to protect the climate and the invaluable carbon exchange kratom trees contribute to the environment.

Oh dear.  While this disagreement continues, Kratom is readily available in shops that sell CBD and other cannabis derivatives.

What’s especially interesting about this difference of opinion is that the FDA usually keeps hands off —says not one word about—products sold as dietary supplements.  It stays quiet about them as a result of court decisions following passage of the Dietary Supplement Health and Education Act of 1994 (DSHEA), which essentially deregulated herbal supplement products.

But the FDA has plenty to say about Kratom.  That the agency argues that Kratom is not a drug, supplement, or food additive, means that it views Kratom as demonstrably harmful.

In situations like this, I tend to invoke the precautionary principle: see proof of safety before using it.  I prefer to head off trouble whenever possible.

But this situation raises an interesting question.  If the FDA thinks Kratom is all that bad, why isn’t it acting to take it off the market?  Or stating that it wishes it could but DSHEA won’t let it.  When the FDA tried to ban potentially harmful supplements, the makers of those supplements took the FDA to court.  The courts generally ruled in favor of the supplement makers.  Go figure.

Caveat emptor.
