Cargill is selling its Chinese poultry business to venture capital company

This article in Feed & Grain caught my attention: Cargill intends to sell its poultry business in China to private equity firm DCP Capital, according to reports.

Cargill is the tenth largest broiler producer in the world; it was responsible for the slaughter of an astonishing 625 million broilers last year, of which 49 million were in China.

You don’t hear much about Cargill because it is not publicly traded.  It is family held, but huge:  155,000 employees, annual revenues of more than $134 billion.

It makes that money from food oils, ingredients, grains, oilseeds, cotton, animal feed, and financial services.

According to this article,

Cargill in 2013 inaugurated its integrated poultry operation in Lai’an, Anhui, China, which included every stage of the supply chain: breeding, raising, feed production, hatching, slaughtering and processing…The company also opened a new US$48 million poultry complex in Chuzhou, Anhui, in 2019. That operation included breeding, raising, feed production, hatching and primary and further processing capabilities.

Now, Cargill is selling off its Chinese enterprises to venture capital.

Cargill must think it best to get out of China.

The venture capital company must think money can still be made there.

This, it seems to me, is an example of what is happening to the global food supply.

It is no longer about making sure that people have enough to eat and do not go hungry.

Food is about making money for investors.

That means keeping costs as low as possible, regardless of the effects on health or the environment.

Industry-funded study of the week: meat, the microbiome, and cardiovascular risk

Christina Leffel, a public health nutritionist in Florida, sent this one, which with both find amusing.

The study: Effects of Adding Lean Red Meat to a U.S.-Style Healthy Vegetarian Dietary Pattern on Gut Microbiota and Cardiovascular Risk Factors in Young Adults: a Crossover Randomized Controlled Trial – The Journal of Nutrition.  VOLUME 153, ISSUE 5P1439-1452, MAY 2023, https://doi.org/10.1016/j.tjnut.2023.03.013

Method:  19 participants consumed 3 study diets in random order: 1) healthy lacto-ovo vegetarian diet (LOV); 2) LOV plus 3 ounces/d of cooked unprocessed lean red meat (URM); and 3) LOV plus 3 ounces/d of cooked processed lean red meat (PRM). Measures: Fecal and fasting blood samples.

Results: The addition of unprocessed or processed lean red meats to a LOV HDP did not influence short-term changes in bacterial taxonomic composition.  When the data from all three diets were combined, “changes in some bacteria were associated with improvements in TC, LDL-C, triglycerides, and HDL-C concentrations, and TC/HDL-C ratio.”

Conclusions:  Healthy young adults who adopt an HDP that may be vegetarian or omnivorous, including lean red meat, experience short-term changes in gut microbial composition, which associate with improvements in multiple lipid-related cardiovascular risk factors.

Funding: “The study was cofunded by the Pork Checkoff, North Dakota Beef Commission, Beef Checkoff, and Foundation for Meat and Poultry Research and Education. The supporting sources had no role in study design; collection, analysis, and interpretation of data; writing of the report; or submission of the report for publication.

Author disclosures: “During the time this review was conducted, WWC received funding for research grants, travel or honoraria for scientific presentations, or consulting services from the following organizations: U.S. National Institutes of Health, U.S. Department of Agriculture (Hatch Funding), Pork Checkoff, National Pork Board, Beef Checkoff, North Dakota Beef Commission, National Cattlemen’s Beef Association, Foundation for Meat and Poultry Research and Education, American Egg Board, Whey Protein Research Consortium, National Dairy Council, Barilla Group, Mushroom Council, and the National Chicken Council. Additionally, SRL received funding for research grants, travel or honoraria for scientific presentations, or consulting services from the following organizations: U.S. National Institutes of Health, U.S. Department of Agriculture, National Science Foundation, Showalter Research Trust, Grain Foods Foundation, CP Kelco US, OLIPOP, Inc, Council for Responsible Nutrition. YW, T-WLC, MT, and CMC declare no conflict of interest. The funder and these other organizations had no role in the design and conduct of the study, analysis, interpretation of the results, and writing of the manuscript.”

Comment: This is yet another industry-funded study in which the funder claims no role–a statement that always makes me laugh.  That’s what they all say, despite much evidence that the funding influence in such situations can be considerable, although unrecognized.  For details, see my book, Unsavory Truth: How Food Companies Skew the Science of What We Eat.

The meat industry, apparently, is trying to convince vegetarians that they can eat any kind of meat they want and not affect their cardiovascular risk.  This, of course, contradicts tons of other evidence, including associations with cancer risk.  These risks may not be mediated through the microbiome, however.  What this study says is that if you are worried about the risks of meat, you don’t have to worry that it changes your microbiome much, at least under the conditions of this study.

Weekend Reading: Ultraprocessed People!

This absolutely superb—informative, eminently readable, compelling—book makes the strongest possible case for the benefits of not eating ultra-processed foods.

These, you may recall, are produced by industrial means, loaded with unfamiliar and questionable food additives, unable to be made in home kitchens, and designed deliberately to be irresistibly delicious, if not addictive, so as to make profits for food companies.

They also encourage people to eat more than they realize, and are consistently associated with poor health.

Van Tulleken is a British physician, scientist, and television star with his twin brother Xand.

Although I am thoroughly familiar with just about everything in this book having written extensively about these topics myself, I still found it to be a great read.

Van Tulleken tells stories really well.  I was hooked on page 30 with the description of Lyra, his 3-year-old daughter’s first encounter with a breakfast cereal aimed at kids.  He had decided to do a Morgan Spurlock  (Super Size Me!) experiment on himself and eat mainly ultra-processed foods for as long as he could stand it.  He began with a breakfast of Coco Pops cereal.

I had assumed that, having never tried Coco Pops, she [Lyra] wouldn’t have any interest in them.  But Kellogg’s had got her hooked before she’d had a mouthful.  She knew that here was a product designed with a three-year-old in mind.  Again, I told her no, so she collapsed on the floor crying and screaming with rage…My lingering doubts [about this cereal] were irrelevant ….Lyra had crawled out from under the table, filled her bowl and started to eat great fistfuls of dry Coco Pops, wide-eyed and ecstatic.  Defeated, I poured out the milk, and read the ingredients…Lyra put her ear to the bowl and shut her eyes, entranced. She then began to eat again.

And eat.  And eat.  As I watched her, it seemed she wasn’t fully in control…Lyra had hardly taken a breath.  I normally have to do a little cajoling at mealtimes, but the first bowl of Coco Pops had simply disappeared.  When I tried to suggest that one bowl was enough, the idea was immediately dismissed.  It felt like advising a smoker to stick to one cigarette.  Her eating wasn’t just mindless: it was trancelike.

This is just what ultra-processed foods are supposed to do.

Van Tulleken calls for government policies to be made without food company involvement, and for policies to restrict the marketing of such foods.

Yes!

The book is published today by Norton. I thought it was a great read.

New report on conflicts of interest in health research

Sponsor Influences on the Quality and Independence of Health Research: Proceedings of a Workshop
This report summarizes the proceedings of a workshop on the effects of industry funding in biasing health—and, therefore, food and nutrition—research.

The workshop covered the ways that funding sources (especially corporate funders) influence research quality and outcomes (precisely the topic of my book, Unsavory Truth: How Food Companies Skew the Science of What We Eat.

The report is a succinct yet thorough summary of the research on the effects of funding on research design, outcome, and interpretation.

Some of the speakers:

This report is a great place to begin if the topic is new to you.

And so is this, of course.

The Daily Harvest mystery—a cause at last?

Thanks to Bill Marler for keeping us all up to date on the Daily Harvest saga.  He keeps up with the literature and writes, Is the Tara mystery closer to being solved?

My most recent post on this mystery was almost a year ago.

To review: Daily Harvest is a company that makes and ships preprepared vegan frozen meals, one of which, French Lentil + Leek Crumbles, has been recalled after several hundred people who ate it developed serious problems with their livers and gall bladders.

This was no trivial incident.  The FDA reported “As of 10/18/2022, there were 393 adverse illness reports in 39 states with 133 hospitalization and 0 deaths.”  But it could not detrmine the specific cause or route of contamination.

My post had breaking news:

The ingredient that caused the illnesses among people who consumed Daily Harvest’s French Lentil + Leek Crumbles has been identified, sort of.  As suspected, it’s the tara flour.  But what’s the toxin in the tara flour?  That, we still don’t know.

Now we have a new study: Is Baikiain in Tara Flour a Causative Agent for the Adverse Events Associated with the Recalled Frozen French Lentil & Leek Crumbles Food Product? A Working Hypothesis. 

In summary, the results of these initial studies support a working hypothesis that the adverse events reported by individuals consuming the Daily Harvest Crumbles product originate from the tara flour ingredient and are due, at least in part, to high levels of nonprotein amino acids (e.g., baikiain). It is further hypothesized that in vivo metabolism of metabolically unstable baikiain results in a toxic metabolite(s) that depletes glutathione and/or is an irreversible enzyme inhibitor (for L-pipecolate oxidase), resulting in adverse events which are dependent on the dose consumed and potentially exacerbated for individuals that have specific genetic predispositions.

Baikiain, which I had never heard of, is an analog of the amino acid proline.  In bacteria, it catalyzes proline destruction.  If it does this in humans, it also might account for the liver toxicity experienced by people who ate the Daily Harvest frozen meals containing tara.

The authors of the tara flour study identified baikiain in the flour.  They gave baikiain to mice, who did not fare well with it.

The hypothesis here is that some people are more susceptible to the toxic effects of baikiain than others.  The French Lentil + Leek Crumbles were sent to 26,000 customers, of which 400 or so got sick, more than 100 of them badly enough to have to be hospitalized; some required surgery.

The lesson here is that food ingredients need better testing.   Whoever makes tara must consider it GRAS (generally recognized as safe) for human consumption.

As Tom Neltner writes,

Tara flour is yet another example of how FDA’s GRAS program is broken—putting the health of Americans at unnecessary risk. FDA should use its big food reboot to fix the program so that we can have confidence in the safety of our food. The agency should also work with members of Congress who have introduced bills intended to fix GRAS and to have FDA reevaluate old food safety decisions in light of new science.

Amen to that.

The Debt Limit bill: a national tragedy

Is anyone else as upset as I am about the Debt Limit bill just passed by the House and Senate and signed by the President?

Senator Bernie Sanders, maybe.  Here’s why he voted against it.

Yes, the bill:

  • Averted a default on the debt which everyone agrees would have been catastrophic (but the crisis should have been prevented in the first place)
  • Will probably not cut SNAP benefits by much if at all (if you believe the Congressional Budget Office)
  • Could have been a lot worse (a very low bar)
  • Is considered a big win by the White House (oh dear)

But, and it’s a big but:

  • It proved that bullying works.

The bullies know it, and are exulting.

The Farm Bill is next.  Watch what the bullies do to it.

What ever happened to government of the people, by the people, for the people?

Existential angst, anyone?  I’ve got plenty.

Conflicted interest of the week: multivitamins and memory

Here’s another one that several readers have asked me about: Multivitamin Supplementation Improves Memory in Older Adults: A Randomized Clinical Trial.  Authors: American Journal of Clinical Nutrition. DOI:https://doi.org/10.1016/j.ajcnut.2023.05.011

The study: “Participants were randomly assigned to a daily multivitamin supplement (Centrum Silver) or placebo and evaluated annually with an Internet-based battery of neuropsychological tests for 3 y.”  Primary outcome measure: change in episodic memory (immediate recall performance on the ModRey test, after 1 y of intervention).  Secondary outcome measures: changes in episodic memory over 3 y of follow-up,  and in performance on neuropsychological tasks of novel object recognition and executive function over 3 y.

Results: “Compared with placebo, participants randomly assigned to multivitamin supplementation had significantly better ModRey immediate recall at 1 y, the primary endpoint (t(5889) = 2.25, P = 0.025), as well as across the 3 y of follow-up on average (t(5889) = 2.54, P = 0.011). Multivitamin supplementation had no significant effects on secondary outcomes…we estimated that the effect of the multivitamin intervention improved memory performance above placebo by the equivalent of 3.1 y of age-related memory change.”

Conlusion: “Daily multivitamin supplementation, compared with placebo, improves memory in older adults.”

Conflict of interest: HDS, JEM, and AMB received investigator-initiated grant support to their institutions from Mars Edge. Pfizer Consumer Healthcare (now Haleon) provided support through the partial provision of study pills and packaging. HDS received 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 the
American Society of Nutrition during the conduct of the study. No funding sources had a role in the design and conduct of the study; collection, management, analysis, and interpretation of the data; preparation, review, or approval of the manuscript; and the decision to submit the manuscript for publication.

Funding: This work was supported by an investigator-initiated grant from Mars Edge, a segment of Mars Inc dedicated to nutrition research. Pfizer Consumer Healthcare (now Haleon) provided support through the
partial provision of study pills and packaging.

Comment:  This study continues to surprise me.  As I’ve written before, it is part of the COSMOS trial, which is also supported by grants from NIH and a private foundation.  In my previous post on it, I noted that despite being funded by Pfizer (which makes Centrum Silver multivitamin supplements), the study did not show benefits of the supplement for prevention of cardiovascular disease or cancer—a rare exception to the rule that industry-funded studies tend to favor the sponsor’s interests.  But here we go again, this time with an equally surprising result but for a different reason: most multivitamin studies have shown no benefits whereas this one says if you take Centrum Silver, it will give you another three years of no loss in memory.  Wow!  I’ll be Pfizer is thrilled.

Here’s what the NIH National Center for Complementary and Integrative Health says about multivitamins:

Multivitamins/multiminerals (MVMs) are the most frequently used dietary supplements, with close to half of American adults taking them. MVMs cannot take the place of eating a variety of foods that are important to a healthy diet. Foods provide more than vitamins and minerals. Many foods also have fiber and other substances that can provide health benefits. However, some people who don’t get enough vitamins and minerals from food alone, or who have certain medical conditions, might benefit from taking one or more of these nutrients found in single-nutrient supplements or in MVMs. However, evidence to support their use for overall health or disease prevention in the general population remains limited.

Some of its conclusions:

  • Most individuals can get all of the necessary vitamins and minerals through a healthy eating pattern of nutrient-dense foods.
  • Taking an MVM increases overall nutrient intake and helps some people get the recommended amounts of vitamins and minerals when they can’t or don’t get them from food alone.
  • There’s no standard or regulatory definition for MVMs, or any dietary supplement, as to what nutrients they must contain or at what levels. .
  • People with healthier diets and lifestyles are more likely to take dietary supplements, making it hard to identify any benefits from their use. There’s no convincing evidence that MVMs help prevent chronic disease.

We will see whether this study causes the Center to change any of this.

Weekend reading: the loss of small dairy farms

I’m just getting to this report from Food and Water Watch: The Economic Cost of Food Monopolies: Dirty Dairy Racket

Food & Water Watch took a look at what’s happening to the U.S. dairy industry.  Its conclusions are not surprising if you have been following these trends.

  • Big dairies have driven out small.  Only about 30 percent of all U.S. milk is produced on family-scale farms.
  • Dairy is not profitable.  “Thanks to the gutting of federal supply management policy,” overproduction and increased production costs gave caysed milk prices to plummet.
  • Consolidation doesn’t help.  Three dairy coops control 83 percent of milk sales: DFA (Dairy Farmers of America), Land O’ Lakes, and California Dairies, Inc.).

Here’s one comparison: Dairy association CEP salaries as compared to dairy farmer income.

The next Farm Bill could help fix some of this by:

  • Restoring supply management
  • Stopping proliferation of factory dairy farms
  • Reforming the farm safety net
  • Setting fair prices
