RFK, Jr to head HHS: brilliant move or catastrophe?

I spent a lot of time last week responding to reporters’ questions about Trump’s appointing Robert F. Kennedy, Jr to head the Department of Health and Human Services.

Here’s what the president-elect said about the appointment on Twitter (X):

For too long, Americans have been crushed by the industrial food complex and drug companies who have engaged in deception, misinformation, and disinformation when it comes to Public Health…HHS will play a big role in helping ensure that everybody will be protected from harmful chemicals, pollutants, pesticides, pharmaceutical products, and food additives that have contributed to the overwhelming Health Crisis in this Country. Mr. Kennedy will restore these Agencies to the traditions of Gold Standard Scientific Research, and beacons of Transparency, to end the Chronic Disease epidemic, and to Make America Great and Healthy Again!

Trump has instructed Mr. Kennedy to end chronic disease and “Go wild on food.”

In various statements, Mr. Kennedy has said he wants to get rid of “poisons”

  • Ultra-processed foods in schools
  • Artificial colors in cereals
  • Chemicals, pollutants, pesticides
  • Mercury in fish
  • Fast food

He also wants to

These are the kinds of things I’ve been saying and writing about for decades!

[He also is pushing for some things that are much less well grounded in science: getting rid of grains for kids, seed oils, and fluoride in drinking water; deregulating raw milk; and firing all nutrition scientists on day 1].

If he really does do what he’s promising here, it means taking on the food industry, in a way that no government has ever done, and Trump showed no signs of doing in his first term.

What can we expect?  I have no idea, but thist sure will be interesting to watch.

Mother Jones calls Kennedy’s appointment “a genuine catastrophe.”

For charges of hypocrisy, click here.

Civil Eats asked a bunch of people to predict “The Path Forward for Food and Ag.”  Here’s what I said.

I wish I had a crystal ball to say how food and agriculture issues would play out over the next four years, but all I have to go on is what Trump and his followers say. If we take them at their word, then we must expect them to implement their Project 2025 plan, which replaces one deep state with another that favors conservative business interests and ideology. This calls for replacing staff in federal agencies with Trump loyalists and dismantling them, stopping the USDA from doing anything to prevent climate change, reforming farm subsidies (unclear how), splitting the farm bill to deal separately with agricultural supports and SNAP, reducing SNAP participation by reinstating work requirements and reducing the Thrifty Food Plan, and making it more difficult for kids to participate in school meals.

On the other hand, some of the plans make sense: eliminating checkoff programs and repealing the sugar program, for example. So do some of Robert F. Kennedy, Jr.’s goals: Make America Healthy Again by focusing on chronic disease prevention, getting harmful chemicals out of kids’ foods, and getting rid of conflicts of interest among researchers and agency staff. It’s too early to know how much of this is just talk, but I’m planning to do what I can to oppose measures I view as harmful, but to strongly support the ones I think will be good for public health.

Industry-funded study of the week: microalgae of all things

No food industry is too small or too obscure to fund research in its own interest.  Try this one, for example.

Effects of Supplementation with a Microalgae Extract from Phaeodactylum tricornutum Containing Fucoxanthin on Cognition and Markers of Health in Older Individuals with Perceptions of Cognitive Decline. Yoo C, Maury J, Gonzalez DE, Ko J, Xing D, Jenkins V, Dickerson B, Leonard M, Estes L, Johnson S, et al.  Nutrients. 2024; 16(17):2999. https://doi.org/10.3390/nu16172999

Background: Phaeodactylum tricornutum (PT) is a microalgae extract that contains fucoxanthin and has been shown to enhance cognitive function in younger populations.

Purpose: The present study assessed if PT supplementation affects cognition in healthy, young-old, physically active adults with self-perceptions of cognitive and memory decline.

Methods: Forty-three males and females…with perceptions of cognitive and memory decline completed the double-blind, randomized, parallel-arm, placebo-controlled intervention clinical trial. Participants were…randomly allocated to their respective 12-week supplementation interventions, which were either the placebo (PL) or 1100 mg/day of PT containing 8.8 mg of fucoxanthin (FX).

Results: FX supplementation significantly affected (p < 0.05) or exhibited tendencies toward significance (p > 0.05 to p < 0.10 with effect sizes ranging from medium to large) for word recall, picture recognition reaction time, Stroop color–word test, choice reaction time, and digit vigilance test variables.

Conclusions: The results demonstrate some evidence that FX supplementation can improve working and secondary memory, vigilance, attention, accuracy, and executive function.

Funding: Microphyt (Baillargues, FRA) funded this study through a grant (Microphyt #410991) to Texas A&M University.

Conflicts of interest: J.M. and R.P. are sponsor-affiliated researchers who therefore have conflicts of interest in study results. They provided input on study design but were not involved in data collection or analysis. R.B.K. has conducted grant and contract-funded research on nutritional supplements awarded to the universities he has been affiliated with, received an honorarium for making scientific presentations, and served as a paid scientific expert. He has no financial conflicts of interest with the study sponsor or product evaluated in this study. The remaining coauthors report no financial conflicts of interest.

Comment: I like “some evidence.”  That suggests the evidence is not particularly impressive.  The study found positive conclusions, not surprising since two of the authors work for the sponsoring company.  Industry-funded studies almost invariably find conclusions that favor the sponsor’s interests.  Otherwise, why bother to sponsor research.  That’s its point: marketing.

Industry-funded review of the week: strawberries (off season)

Thanks to Stephen Zwick of Regenetarianism for sending this one.

Charoenwoodhipong, P., Zuelch, M. L., Keen, C. L., Hackman, R. M., & Holt, R. R. (2024). Strawberry (Fragaria x Ananassa) intake on human health and disease outcomes: a comprehensive literature reviewCritical Reviews in Food Science and Nutrition, 1–31. https://doi.org/10.1080/10408398.2024.2398634

From the Abstract

Of the 60 articles included in this review, 47 were clinical trials, while 13 were observational studies. A majority of these studies reported on the influence of strawberry intake on cardiometabolic outcomes. Study designs included those examining the influence of strawberry intake during the postprandial period, short-term trials randomized with a control, or a single arm intake period controlling with a low polyphenolic diet or no strawberry intake. A smaller proportion of studies included in this review examined the influence of strawberry intake on additional outcomes of aging including bone and brain health, and cancer risk. Data support that the inclusion of strawberries into the diet can have positive impacts during the postprandial period, with daily intake improving outcomes of lipid metabolism and inflammation in those at increased cardiovascular risk.

Funding: This work was supported by the California Strawberry Commission (CSC). PC, MLZ, and RRH received financial support from the CSC for this work.

Disclosure statement: No potential conflict of interest was reported by the authors.

Comment: I can never get over how industry-funded authors do not view industry funding as a conflict of interest when so much evidence confirms that such funding strongly influences research design and interpretation.  For the record, I review that evidence in my book Unsavory Truth: How Food Companies Skew the Science of What We Eat.

This sure looks like a standard industry-funded study with a predictable outcome favorable to the strawberry industry in this case.

Strawberries are a fine food, delicious, nutritious, and obviously healthful.  But a superfood responsible on their own for disease prevention?

How I wish.

This is marketing research.

A brief comment on the election’s food politics

I saw this on Twitter (X):

For the video, click here.

I’m for all three actions.  I’ve argued for years for getting rid of conflicts of interest and focusing resources on preventing chronic disease.

I can’t wait to find out how the new administration plans to accomplish these goals.   We all need to hold it accountable for delivering on these promises.

Industry-funded study of the week: again, potatoes

Potatoes, a source of rapidly absorbable starch, have such a bad reputation that some nutritionists advise against eating them.  I am not one of them.  I enjoy eating potatoes and think their blood sugar-raising effects depend on how they are prepared and how muh of them you eat.

The potato industry, alarmed about advice not to eat potatoes, funds research to prove they are healthy, or at least do no harm.  Hence:

Djousse L, Zhou X, Lim J, Kim E, Sesso HD, Lee IM, Buring JE, McClelland RL, Gaziano JM, Steffen LM, Manson JE. Potato Consumption and Risk of Type 2 Diabetes Mellitus: A Harmonized Analysis of 7 Prospective Cohorts. J Nutr. 2024 Oct;154(10):3079-3087. doi: 10.1016/j.tjnut.2024.07.020.

  • Results: In the primary analysis, total potato intake was not associated with T2D risk:…In secondary analyses, consumption of combined baked, boiled, and mashed potatoes was not associated with T2D risk, whereas fried potato consumption was positively associated with T2D risk:.
  • Conclusions: Although consumption of total potato is not associated with T2D risk, a modest elevated risk of T2D is observed with fried potato consumption.
  • Conflict of interest: LD received investigator-initiated grant from the Alliance for Potato Research and Education (as principal investigator).
  • Funding: This project was supported by a grant from the Alliance Potato Research and Education (principal investigator: LD).  A lengthy list of other funders, including NIH and Mars Edge, follows.

Comment: This potato industry-funded study did not find potatoes to be associated with type 2 diabetes, which must be a huge relief to this industry. But the study did find a weak association (barely statistically significant) beween fried potatoes and type 2 diabetes.  The Potato Alliance ought to be delighted with this result.   I’m guessing the result is real (it’s what I would have predicted), but I’d be happier with it if it had been conducted by investigators independent of industry funding.  As it is, it looks like the potato industry got what it paid for.

Industry-funded opinion of the week: Forget about ultra-processed

A reader, Bart Peuchot, writes:

I would be very interested to have your view on this new publication for Nature.

As you taught me, I checked the competing interests and it seems to be a perfect industry-funded publication.

And then ,I ran across this Tweet (X) from @Stuart Gillespie:

New paper concluding “more research needed”
…brought to you by Nutrition Foundation of Italy…
…which in turn is brought to you by
…..@Nestle @McDonalds @CocaCola Ferrero, Barilla, Danone et al…

Well.  What  is this about?

I went right to the paper: Visioli, F., Del Rio, D., Fogliano, V. et al. Ultra-processed foods and health: are we correctly interpreting the available evidence?. Eur J Clin Nutr (2024). https://doi.org/10.1038/s41430-024-01515-8

Aha! Another attack on the concept of ultra-processed foods.  The article concludes

the available evidence on how different UPFs have been associated with health, as well as the results of studies examining specific food additives, call into question the possibility that ultra-processing per se is the real culprit. It is possible that other unaccounted for confounding factors play an important role. Future, urgently needed studies will clarify this issue.

The Italian food industry has been especially active in opposing NutriScore labels and anything else that might discourage sales of foods high in sugar, salt, and saturated fat.

But it is not alone in pushing back against the concept of  ultra-processed foods—an existential threat to junk food manufacturers.

Here, for example, is Hank Cardello,  the Executive Director of Leadership Solutions for Health + Prosperity at Georgetown’s Business School writing in Forbes:: New Report Highlights The Sweet Side Of Ultra-Processed Foods.

With ultra-processed foods (UPFs) replacing “junk food” as the new bogeyman for public health advocates, a new study published by  the Georgetown University Business for Impact Center (full disclosure: I am one of the authors) reveals that all UPFs are not created equal. The report spotlighted that candy in particular was the exception, since that category contributes only 6.4% of added sugars and less than 2% of our calories. The most surprising discovery is that the “healthiest of the healthiest” consumer cohort in the study purchased candy 26% more frequently than the general population.

The report: New Consumer Insights on Ultra-Processed Indulgent Foods: How Confectionery Products Are Different.

Candy behaves differently from other ultraprocessed indulgent products. New NMI and NHANES data re-confirm that candy is different and should not be lumped together with other indulgent products. Consumers do not overconsume  chocolate and candy, so targeting these foods will not impact obesity. An approach that focuses on product categories that consumers with the highest BMIs eat and drink the most will be more effective.

OK, readers: Take a guess at who paid for this.

Funding for this paper was provided by the National Confectioners Association.

As I keep saying, you can’t make this stuff up.

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.
