This one was sent to me by a reader: Animal vs. Plant Protein: New Research Suggests That These Protein Sources Are Not Nutritionally Equivalent: Scientists found that two-ounce-equivalents (oz-eq) of animal-based protein foods provide greater essential amino acids (EAA) bioavailability than the same quantity of plant-based protein foods. The study challenges the Dietary Guidelines for Americans (DGAs) which suggest these protein sources are nutritionally equivalent.

I went right to the study: “Effects of Consuming Ounce-Equivalent Portions of Animal- vs. Plant-Based Protein Foods, as Defined by the Dietary Guidelines for Americans on Essential Amino Acids Bioavailability in Young and Older Adults: Two Cross-Over Randomized Controlled Trials” by Gavin Connolly, Joshua L. Hudson, Robert E. Bergia, Eric M. Davis, Austin S. Hartman, Wenbin Zhu, Chad C. Carroll and Wayne W. Campbell, 25 June 2023, Nutrients. DOI: 10.3390/nu15132870

Oh.  It’s in Nutrients, a journal that might as well be called “The Journal of Industry-Funded Research” (authors have to pay for publication of their articles in this journal–2900 Swiss Francs).

The study was designed to demonstrate that protein from animal sources is better than protein from plant sources, immediately raising the question: Who sponsored this study?

Funding: This research was funded by the Pork Checkoff and the American Egg Board—Egg Nutrition Center. 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.

Do the authors report conflicts of interest?  Yes, they do:

Conflicts of Interets: When this research was conducted, W.W.C. received research funding from the following organizations: American Egg Board’s Egg Nutrition Center, Beef Checkoff, Pork Checkoff, North Dakota Beef Commission, Barilla Group, Mushroom Council, and the National Chicken Council. C.C.C. received funding from the Beef Checkoff. R.E.B. is currently employed by Archer-Daniels-Midland (ADM); the research presented in this article was conducted in a former role and has no connection with ADM. G.C., J.L.H., E.M.D., A.S.H. and W.Z. declare no conflict of interest. The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results.

I’m not going to bother going through the methods, results, or other details.  The point here is that industry-funded research has a high probability of producing results favorable to the sponsors’ interests, as happened in this instance.  The statement that the sponsors had no role may or may not be true; it’s hard to know without further investigation, but research on this question demonstrates that the statement is not always accurate.  Funding exerts influence, whether recognized by researchers or not.

A reader who wishes to remain anonymous forwarded this email she received from Kristen Hicks-Roof PhD, RDN, LDN, FAND , Director of Human Nutrition·National Pork Board.

Growing Strong: Animal-Source Foods’ Role in Childhood Development and Sustainable Food Systems

Childhood and adolescence are critically important periods for growth and development. These periods are also key for establishing healthy dietary patterns that can influence eating behaviors and health into adulthood.

During these stages, animal-source foods provide critical nutrients — such as high-quality protein, iron, zinc, choline, and B vitamins — that are not easily replaced from other sources.

In this webinar, Dr. Adegbola Adesogan will:

– Present evidence on the role of animal-source foods in childhood development and impact on future health outcomes

– Review how animal-source foods are a source of key nutrients that support health in children and adolescents

The CPE activity application for this webinar is pending review by the Commission on Dietetic Registration (CDR) and approval for 1.0 CPEU.

Comment

Presumably, the CDR will approve this for continuing education credits required for dietetic licensing.  Also presumably, participants will not learn about the polluting effects of Pork CAFOs or the community lawsuits against them for obnoxious odors and other offenses.  Or the way the pork industry fights back against such complaints.  Or the welfare issues about farrowing crates.  Or complaints about Pork Checkoff programs.

As I’ve noted previously, dietitians are able to fulfill all requirements for continuing education credits from industry-funded courses like this one.

Conflict of interest, anyone?

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?”

This one is about activities of the National Pork Board, a USDA-sponsored checkoff program recipient (see comment at end).  It comes from a reader, Lily Doher, reproduced with her permission.

I receive emails from the National CACFP [Child and Adult Care Food Program] Sponsors Association and occasionally click to see what free trainings they’re offering providers. I was encouraged by a training that described how providers play a pivotal role in developing childrens’ food habits and preferences and how providers can create positive food environments that support healthy eating. I clicked on the link and was surprised to see the training was sponsored and presented by the National Pork Board, and even more surprised to see the egregious industry influence throughout the training. Hosted by a registered dietitian nonetheless.

• “Empowering children to explore new foods, like lean pork, is key to addressing nutritional challenges faced by children.”
• “…pork has a huge role to play in discussions around food choice, exposure, language, and acceptance in children.”
• “Dr. Hicks-Roof then shed light on the crucial role of pork in shaping children’s food preferences and dietary habits…”
• “She also shared the science behind hunger and satiety, emphasizing the pivotal role of protein intake and importance of lean pork in informing conditional satiety.”
• ” Additionally, she shed light on pork’s affordability, nutrition and cultural significance as pork is a widely consumed meat globally.”
• “Dr. Hicks-Roof clarified that pork is the ultimate carrier food for busting through food neophobia in children, unlocking a new world of varied food exposures, and supporting opportunities to use positive, inclusive language during conversations about food with children.”

While this training is being highlighted by National CACFP, this type of industry influence is ultimately what led me to leave the Academy of Nutrition and Dietetics, and I am disheartened to once again see a fellow registered dietitian be the puppet for Big Food. Our children, and the providers that care for them, deserve better.

Comment: CACFP is the USDA’s Child and Adult Care Food Program.  It provides reimbursements to providers of meals at child care centers, day care homes, and adult day care centers.  I wrote about it most recently in a previous “weekend reading” post.  Of course the National Pork Board, which runs the USDA-sponsored checkoff program, wants to encourage dietitians to promote pork.  It must welcome the opportunity to provide free continuing education credits.  Dietitians are required to complete 75 such credits every five years.  As I’ve written previously, they can easily do that with free industry-sponsored coursses.

Do those courses influence what dietitians tell clients?  Perhaps the Pork Board can answer that question (I wonder if it ever did before-and-after surveys).  I’m guessing it must view the expense as worthwhile.

Thanks to a reader, Kevin Mitchell, for sending this news item: Animal vs. Plant Protein: New Research Suggests That These Protein Sources Are Not Nutritionally Equivalent.

Scientists found that two-ounce-equivalents (oz-eq) of animal-based protein foods provide greater essential amino acids (EAA) bioavailability than the same quantity of plant-based protein foods. The study challenges the Dietary Guidelines for Americans (DGAs) which suggest these protein sources are nutritionally equivalent.

I went right to the source.

• The study: Connolly G, Hudson JL, Bergia RE, Davis EM, Hartman AS, Zhu W, Carroll CC, Campbell WW. Effects of Consuming Ounce-Equivalent Portions of Animal- vs. Plant-Based Protein Foods, as Defined by the Dietary Guidelines for Americans on Essential Amino Acids Bioavailability in Young and Older Adults: Two Cross-Over Randomized Controlled Trials. Nutrients. 2023; 15(13):2870. https://doi.org/10.3390/nu15132870
• Objectives: We assessed the effects of consuming two oz-eq portions of pork, eggs, black beans, and almonds on postprandial EAA bioavailability in young and older adults.
• Methods: We conducted two investigator-blinded, randomized crossover trials in young (n = 30; mean age ± SD: 26.0 ± 4.9 y) and older adults (n = 25; mean age ± SD: 64.2 ± 6.6 y). Participants completed four testing sessions where they consumed a standardized meal with two oz-eq of either unprocessed lean pork, whole eggs, black beans, or sliced almonds.
• Conclusions: Pork resulted in greater EAA bioavailability than eggs in young adults (p < 0.0001), older adults (p = 0.0007), and combined (p < 0.0001)… The same “oz-eq” portions of animal- and plant-based protein foods do not provide equivalent EAA content and postprandial bioavailability for protein anabolism in young and older adults.
•  Funding: This research was funded by the Pork Checkoff and the American Egg Board—Egg Nutrition Center. 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.

Comment: It is very much in the interest of the Pork Checkoff and the Egg Board t,o demonstrate that animal-source food protein is better for you than proteins from plant sources—and to cast doubt on any evidence to the contrary.  Proteins, whether from animal or plant sources, contain precisely the same 20 amino acids, although in different proportions.  Animal proteins are closer in amino acid composition than are plant proteins but if you eat a variety of plant foods you will get the amino acids you need.   People who eat largely plant-based diets are generally healthier than people who eat a lot of animal-based foods.  The conclusion of this study does not change that overall conclusion.  This, then, is another industry-funded study with predictable results.

A member of the Academy of Nutrition and Dietetics, the professional association for Registered Dietitian Nutritionists, sent me this emailed announcement from Pork & Partners, a program of the National Pork Board Checkoff.

The accompanying message:

The Pork & Partners website emphasizes the nutrition, health, sustainability, and cleanliness of pig production.

I couldn’t find anything on the site about confinement of pregnant sows, the subject of a recent Supreme Court decision, or the many lawsuits over offensive odors from pig CAFOs.

Pork producers must not want dietitians talking about such things.  Hence: free CPEUs.

To the surprise of everyone as far as I can tell, the Supreme Court has upheld California’s ban on pork from states that allow pork producers to confine pregnant sows in gestation crates.

California, which consumes 13% of U.S. pork but imports 99% of it, said it would only permit import of pork from producers who give pregnant sows at least 24 square feet of space.

Gestation crates confine pregnant sows so tightly that all they can do is stand up and lie down.

I would not call myself an animal rights advocate, but having been pregnant myself a couple of times, I found myself deeply upset when I saw sows confined like that.

At the time, I was on the Pew Commission on Industrial Farm Animal Production.

We asked why they were doing this.  Answer: To keep the sow from crushing her piglets—and to make it easier to feed and clean the animals.

Fortunately, Bill Niman was also on the commission and whisked us off to one of the Niman Ranch farms where we could see sows, each in her own hoop tent, happily tending to piglets and rolling in mud when she felt like it.

Did the sows crush their piglets?  Not when they had ample room to move around ard were not stressed.  Yes, they didn’t produce quite as many piglets, but the meat tasted a lot better.

So I’m happy to see the pig crates disappear, which they will have to if anyone wants to sell pork in California.

This case is not really about animal rights though.  It is about states’ rights to make laws like this one.

The pork producers challenged California’s law.  But Justice Neil Gorsuch writing for the majority said:

California voters overwhelmingly endorsed the “ethical pork” law in 2018 and have the right to decide what products appear on store shelves…Companies that choose to sell products in various States must normally comply with the laws of those various States, “While the Constitution addresses many weighty issues, the type of pork chops California merchants may sell is not on that list.”

It’s amazing to have something good come out of this court.  Maybe pig crates will set a precedent.
