Industry-sponsored studies of the week: two on omega-3 supplements

I.  Expert Opinion on Benefits of Long-Chain Omega-3 Fatty Acids (DHA and EPA) in Aging and Clinical Nutrition, Troesch B, et al.  Nutrients 2020;12(9):2555.

Conclusion: The evidence to date indicates that the provision of DHA and EPA through capsules, oral nutrition supplements, or enteral or parenteral formulas can help to regulate the inflammatory environment in a number of medical conditions and that this is linked in many cases to improved function, clinical course and outcomes.

Funding: DSM Nutritional Products Ltd. provided financial support to organize and invite experts to participate as discussants, based on their expertise on the role of DHA and EPA in aging as well as different medical conditions, as well as financial support for the development of this review.
Conflicts of Interest: B.T. and I.W. are employed by DSM Nutritional Products Ltd.; M.E. acts as an advisor for DSM, received travel reimbursement from DSM and is a member of the Scientific Board of PM International and President of the Gesellschaft für angewandte Vitaminforschung; A.L. received consulting fees from BBraun, DSM, Nutricia and Smartfish and received honoraria for independent lectures from Abbott, Baxter, BBraun, Fresenius Kabi, Nestlé Health Science, Nutricia and Smartfish; Y.R. received travel reimbursement from DSM; AW receives speaker fees from Baxter Germany, Berlin Chemie, BBraun Melsungen AG, DSM, Ethicon, Falk Foundation Fresenius Kabi Deutschland GmbH, Medtronic and research grants from Baxter, Danone and Mucos; P.C.C. acts as a consultant for DSM, BASF, Danone/Nutricia, Cargill, Smartfish and Fresenius Kabi. A.D.S. has no conflict to declare.
Comment: DSM Nutrition Products is a major seller of dietary supplements, with a highly vested interest in demonstrating the benefits of the supplements it sells.  Evidence on the benefits of omega-3 fatty acid supplements tends to vary enormously.  Some studies, like this one, find benefits.  Other studies do not (see, for example, this, this, or this).  Could funding source have something to do with these differences?  I think yes.  
Before I had a chance to post this one, a reader, Dr. Eliška Selinger, who teaches science methods and nutrition in Prague, sent yet another example, this one not yet published.II.  Effect of Omega-3 Dosage on Cardiovascular Outcomes: An Updated Meta-Analysis and Meta-Regression of Interventional Trials. Aldo A. Bernasconi, PhD; Michelle M. Wiest, PhD; Carl J. Lavie, MD; Richard V. Milani, MD; and Jari A. Laukkanen, MD, PhD.  Article in press Mayo Clin Proc. n XXX 2020;nn(n):1-10 n https://doi.org/10.1016/j.mayocp.2020.08.034

Objectives: “To quantify the effect of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids on cardiovascular disease (CVD) prevention and the effect of dosage.”

Conclusion: “Cardiovascular disease remains the leading cause of death worldwide. Supplementation with EPA and DHA is an effective lifestyle strategy for CVD prevention, and the protective effect probably increases with dosage.”

Potential Competing Interests: “Dr Bernasconi is an employee of the Global Organization for EPA and DHA Omega-3s (GOED), a 501(c)6 not-for profit trade association. GOED’s goals are to increase consumption of omega3s to adequate levels around the world and to ensure that the industry is producing quality omega-3 products that consumers can trust. Dr Wiest has been a guest speaker with travel sponsored by DSM Nutritional Products and the Global Organization for EPA and DHA Omega-3s (GOED); and has received funding from GOED to conduct a meta-analysis on omega-3 fatty acids. Dr Lavie has been a speaker for Amarin Corporation on Vascepa, has consulted for DSM Nutritional Products, and has made an omega-3 educational video at the American Heart Association meeting on November 14, 2016, for the Global Organization for EPA and DHA Omega-3s and also gave a presentation at a GOED-hosted omega-3 conference in Barcelona, Spain, in February 2020. The remaining authors report no potential competing interests.”

Grant Support: “This study was supported by a grant from the Global Organization for EPA and DHA Omega-3s (GOED), Salt Lake City, UT.”

Comment: The Global Organization for EPA and DHA Omega-3s “represents the worldwide EPA and DHA omega-3 industry…Our mission is to increase consumption of EPA and DHA omega-3s…”   Omega-3 fatty acids are essential to human health and are widely available from green leafy vegetables (in the form of ALA) as well as from fish (EPA and DHA).   ALA is converted in the body to EPA and DHA.   The benefits of omega-3 supplements, as I just explained, are not well established.  This trade association for EPA and DHA supplements funded this study to demonstrate the benefits of these products.  Caveat emptor.

Weekend reading: Tom Philpott’s Perilous Bounty

Tom Philpott.  Perilous Bounty: The Looming Collapse of American Farming and How We Can Prevent It.  Bloomsbury, 2020.  

Media of Perilous Bounty

Here’s my blurb:

In Perilous Bounty, Tom Philpott probes what’s wrong with Big Agriculture—examining how it depletes California’s water, poisons water in the Midwest, and ruins soil resources—and proposes ways to reconfigure the food system to better promote health and sustain the environment. This must-read book is deeply researched, compellingly written, and thoroughly inspiring.

And here’s a quick excerpt:

We have reached the limits of “market-as-movement” to transform the food system.  In an economy marked by severe inequality, wage stagnation, and persistently high levels of poverty, the market approach excludes the population that can’t afford to pay the higher prices of organic, local food or devote time to cooking from scratch.  It threatens to create an ecologically robust niche for the prosperous within a dominant food system that quietly lurches on, wrecking the environment and making people sick.  Well-off consumers should vote with their forks three times a day, but the pace of positive change they create has been no match for Big Food’s massive inertia and the rapid advance of climate change.  But something important has emerged over the same period: the stirrings of a new form of movement politics…  [p. 255]

The latest on CBD

I am interested in the politics of CBD edibles and supplements, and have been collecting items.  The big issue, of course, is regulation.

The FDA has a web page devoted to this topic:

FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD)

Here are some recent articles on what’s happening with CBD.

Hunger in America: The landscape in 2020

Before getting into the statistics, let’s start with the on-the-ground reality: real people, often with small children, are too poor to feed themselves and their families properly.  For the human impact of pandemic poverty, see:

Prior to the pandemic, poverty and food insecurity were declining in America.

But now we have pandemic-induced illness, job losses, school closures, business closures.

The USDA won’t report on food insecurity for another year, so it’s difficult to know what’s happening right now.  USDA data on SNAP are available only through April.

Even then, early signs were alarming.

We badly need effective policies to protect people against hunger.

Additional USDA resources

  • Food Security in the U.S.  Food security—access by all people at all times to enough food for an active, healthy life—is one requirement for a healthy, well-nourished population. ERS plays a leading role in Federal research on food security in U.S. households and communities.
  • Food Security in the United States: This product provides information about publicly available data from national surveys that include the U.S. Food Security Survey Module. Technical information is provided to facilitate appropriate use of the data, and links are provided to access data online or to order the data files on CD-ROM.
  • Statistical Supplement to Household Food Security in the United States in 2019: This supplement to Household Food Security in the United States in 2019 describes food insecurity and how it is assessed.

Corporate capture in action: e-mails illustrate the meat industry’s role in keeping plants open despite Covid-19

I’ve written previously (see this one, for example) about the meat industry’s role in keeping plants open despite worker illnesses, but much about the industry’s pressures on government has been based on conjecture.  No more.

In another example of the value of the Freedom of Information Act (FOIA), two groups have obtained e-mails documenting these pressures.

FROM PRO PUBLICA, September 14, 2020: “Emails Show the Meatpacking Industry Drafted an Executive Order to Keep Plants Open: Hundreds of emails offer a rare look at the meat industry’s influence and access to the highest levels of government. The draft was submitted a week before Trump’s executive order, which bore striking similarities.”

The e-mails indicate that the North American Meat Institute (NAMI), the trade association for the meat industry, essentially wrote President Trump’s executive order invoking the Defense Production Act, which forced plants to stay open and workers to continue working under unsafe and highly virus-transmissable conditions.

For example (and look on the site for #6, which does a longer and even more compelling comparison):

FROM PUBLIC CITIZEN, September 15, 2020: “The U.S. Department of Agriculture (USDA) and the meatpacking industry worked together to downplay and disregard risks to worker health during the pandemic, as shown in documents uncovered by Public Citizen and American Oversight through Freedom of Information Act (FOIA) requests.”

The documents show that:

  • The executive order signed by President Donald Trump regarding meatpacking plants, ostensibly invoking the Defense Production Act, was the result of lobbying by the North American Meat Institute, a meat-packing trade association, which prepared what appears to be the first draft of what would become the executive order;
  • The North American Meat Institute repeatedly requested that USDA Secretary Sonny Perdue discourage workers who were afraid to return to work from staying home;
  • Meatpacking plants asked the USDA to intervene on multiple occasions when state and local governments either shut them down over health and safety concerns or sought to impose worker health and safety standards; and
  • Smithfield Foods repeatedly requested that the USDA “order” it to reopen its meat processing plant in Sioux Falls, S.D. – despite no legal basis for such an order.

WHAT’S AT STAKE HERE?

Check out Leah Douglas’s ongoing count of Covid-19 cases among meatpacking workers.  Her figures as of September 18, include at least:

  • 804 meatpacking and food processing plants (496 meatpacking and 308 food processing) and 106 farms and production facilities have had confirmed cases of Covid-19.
  • 59,430 workers (42,606 meatpacking workers, 9,571 food processing workers, and 7,253 farmworkers) have tested positive for Covid-19.
  • 254 workers (203 meatpacking workers, 35 food processing workers, and 16 farmworkers) have died.

To state the obvious: corporate capture of government agencies and the presidency is not good for public health or American democracy.

Industry-funded study of the week: soup prevents obesity?

When I saw the title of this study, I had two questions:

  • Why would anyone do a study like this? (OK, in short-term studies, consuming water or soup before meals reduces immediate calorie consumption, but in the long term?)
  • Who paid for it?  (Getting the answer to this one took some digging).

The study: Association between soup consumption and obesity: A systematic review with meta-analysis. M.Kuroda and K. Ninomiya. Physiology & Behavior,  Volume 225, 15 October 2020, 113103.

Conclusion: “soup consumption is significantly related to lower odds ratio of obesity…suggesting that soup consumption was inversely correlated with a risk of obesity.”

Weekend reading: books about individual foods, avocados this time

Jeff Miller.  Avocado: A Global History.  Reaktion Books, 2020.  

 

I did a blurb for this one:

Avocados is a welcome addition to the Reaktion food series, so filled with splendid facts, figures, and illustrations that I learned something new on every page.   I particularly appreciated Jeff Miller’s discussion of avocados as an international commodity—legally grown and traded but also the target of organized thievery and now too expensive for many of their growers to have for their own use.  This is a fascinating story, beautifully told.

This book comes early in the alphabetical listing of Reaktion Books’ Edible series, which includes dozens of single-food monographs from Apples to Wine.  I didn’t know they had blurbs on the back cover, but I was pleased to do this one, especially because I met Jeff Miller when he took the course I taught with Sidney Mintz in Puerto Rico in 2003 and appreciate his subsequent work as a food studies scholar.

Food companies’ exploitation of Covid-19 for marketing purposes: new report

The NCD [Non-Communicable Disease] Alliance has issued a press release for its latest report, Signalling Virtue, Promoting Harm – Unhealthy Commodity Industries and COVID-19

As the press release explains, the

new report details hundreds of examples of unhealthy commodity industries, led by Big Alcohol, Big Food, and Big Soda, leveraging the COVID-19 pandemic for commercial gain. This report raises concerns of corporate capture during the pandemic by the very industries that are fuelling the burden of NCDs worldwide and putting people at greater risk of severe COVID-19 outcomes.

The Alliance released the report in conjunction with the  Global Week for Action on NCDs and the theme of accountability.

The report includes hundreds of case studies submitted from more than 90 countries of business responses to Covid-19, in these categories.

The report illustrates dozens of examples, and it’s hard to choose the most egregious from among so many possibilities.  I particularly appreciated this one.

This report is well worth a close look.  I found it highly instructive.
