Conflicts of interest in nutrition research: this week’s example

Selenium, antioxidants, cardiovascular disease, and all-cause mortality: a systematic review and meta-analysis of randomized controlled trials. David JA Jenkins, David Kitts, Edward L Giovannucci, Sandhya Sahye-Pudaruth, Melanie Paquette, Sonia Blanco Mejia, Darshna Patel, Meaghan Kavanagh, Tom Tsirakis, Cyril WC Kendall, Sathish C Pichika, and John L Sievenpiper.  The American Journal of Clinical Nutrition, Volume 112, Issue 6, December 2020, Pages 1642–1652

Background: “Antioxidants have been promoted for cardiovascular disease (CVD) risk reduction and for the prevention of cancer. Our preliminary analysis suggested that only when selenium was present were antioxidant mixtures associated with reduced all-cause mortality.”

Results: No association of selenium alone or antioxidants was seen with CVD and all-cause mortality. However, a decreased risk with antioxidant mixtures was seen for CVD and all-cause mortality when selenium was part of the mix.

Conclusion: The addition of selenium should be considered for supplements containing antioxidant mixtures if they are to be associated with CVD and all-cause mortality risk reduction.

Comment: The results are statistically significant, but not by much (RR: 0.90; 95% CI: 0.82, 0.98; P = 0.02); the Confidence Interval reaches 0.98, which is very close to 1.00, which would show no difference.  But that’s not the real reason for my interest in this one.  The real reason in this astounding conflicts-of-interest statement and the disclaimer that follows it.

Disclaimer: The authors have no relevant conflicts of interest over the past 4 y. DJAJ has received funds for dietary studies from Loblaws, which, during the course of his funding, acquired Shopper’s Drugmart, which is a pharmaceutical company that also sells supplements.

Comment: Here’s one reason why I am not a fan of dietary supplements.  Most independently funded studies show no significant benefit when they are given to healthy people.  The industry needs studies like these for marketing purposes.  I’m not, but if you are worried about selenium, try food.

Weekend reading: Jessica Harris’s Vintage Postcards

Jessica Harris. Vintage Postcards from the African World: In the Dignity of Their Work and the Joy of Their Play.  University of Mississippi Press, 2020.

Amazon.com: Vintage Postcards from the African World: In the Dignity of  Their Work and the Joy of Their Play (Atlantic Migrations and the African  Diaspora) eBook: Harris, Jessica B.: Kindle Store

I reviewed this book for Food, Culture, and Society, which published my review online on July 23, 2020.  It won’t appear in print until November 2021.  Emily Contois, the fabulous book review editor, is way ahead.

Here’s what I said about it.

Some years ago, I was in Woods Hole and hopped on the ferry to Martha’s Vineyard to visit Jessica Harris at her cottage in the historic African-American community at Oak Bluffs. I knew her as the distinguished culinary historian, cookbook author, and scholar of the African food diaspora. In the early years of NYU’s food studies program, she taught brilliant courses on food and culture that I sat in on whenever I could. She is now retired from a long teaching career at Queens College.

During that Oak Bluffs visit, Harris showed me boxes packed with old postcards depicting Africans – and their descendants throughout the world – growing, carrying, preparing, and eating food. I couldn’t stop looking at them, and I’ve never stopped wondering what happened to them. This book is the answer, and a perfect fit with the University of Mississippi’s series on Atlantic Migration and the African Diaspora, which Harris edits.

In addition to her other accomplishments, Harris is a passionate deltiologist, a term new to my vocabulary meaning one who collects – and sometimes studies – postcards, which Harris had been doing for fifty years. She begins the book with three short essays – a description of when, how, and where she amassed her collection; a discussion of what can be learned from postcards and the kinds of questions that need to be asked about them (illustrated with about 25 examples); and a history of the introduction and use of postcards from the 1870s on. She also includes guidelines on how to estimate a postcard’s date (not easy).

But most of the book is devoted to 168 color illustrations of postcards from her collection, almost all from the early 1900s. These illustrate people at work and play from Africa, the Caribbean, and the United States in three categories: farm, garden, and sea; marketplace, venders, cooks; and leisure, entertainments, and festivities. Their captions repeat information printed on the front, state whatever is printed or written on the back, and, if the card is stamped, give the date it was mailed. For example, a photograph of a Caribbean sugar warehouse (which reminded me of Kara Walker’s magnificent 2014 “sugar baby” sculpture in Brooklyn’s Domino Sugar Factory), is captioned: “Stacking Bags of Raw Sugar. Back: Post Card British Manufacture. Printed for the Imperial Institute by McCorquodale & Co. Ltd. London. A Red Bromide Photograph. (Divided Back.)” (84).

That’s it. Unless the card has this information, the captions say nothing about who took the picture, where, and in what year, who is depicted, its context, its purpose, or whether it was taken in a studio. In her introductory essay, “”Interrogating the Images,” Harris says “I am not a postcard scholar” (19). She collected and selected the cards for their illustration of culinary or cultural history and colonial exploitation, but also for their beauty, curiosity, or inscrutability. If you want to know more, it’s up to you to find that out and develop your own interpretation.

Despite that protestation, Harris cannot avoid taking a scholar’s approach. She points out the colonial attitudes expressed in the images or their titles–“elegant banana seller” (30), or the bare-breasted women selling foods at a “native” market in Dakar that looks like something out of the early years of National Geographic. This market could not possibly be in Dakar, Harris notes, Senegal is a Muslim country, where women did not appear in public unclothed.

In this era of #BlackLivesMatter, it is uncomfortable to look at images of picturesque poverty or colonial exploitation: “Blacks in a Moorish café” (68), “Zulus at Mealtime” (69), or even “Water coconut vendor” (97) are depicted as exotics. Given its racist history, the United States postcards are particularly problematic: “Polly in the Peanut Patch” (110), “Negro Vegetable Vendor” (123), “Old/Southern Kitchen and Negro Manny” (130) should and do make us squirm. It’s hard to view “Food for contention” (135) as just a charming photograph of a little girl reaching for her brother’s watermelon slice if such images weren’t so fraught with racist meanings.

Each of these images has a story behind it that calls for analysis by food studies scholars. Harris’s Vintage Postcards should inspire all of us to become avid deltiologists.

What does $2 Trillion do for US Food Systems? (Not much, alas)

President Trump’s $2 Trillion relief package is the “Coronavirus Aid, Relief, and Economic Security (CARES) Act of 2020.’’

This 880-page (!) bill addresses food systems in several ways, most of them in “Title I Agricultural Programs” which starts on page 609 like this:.

For an additional amount for the ‘‘Office of the Secretary’’, $9,500,000,000, to remain available until expended, to prevent, prepare for, and respond to coronavirus by providing support for agricultural producers impacted by coronavirus, including producers of specialty crops, producers that supply local food systems, including farmers markets, restaurants, and schools, and livestock producers, including dairy producers: Provided, That such amount is designated by the Congress as being for an emergency requirement pursuant to section 22 251(b)(2)(A)(i) of the Balanced Budget and Emergency 23 Deficit Control Act of 1985.

This sounds good (in Ag-speak, specialty crops are fruits and vegetables), but what this means in practice, according to the New York Times, is

  • About $23.5 billion in assistance to farmers ($9.5 in subsidies, $14 in borrowing authority)

But this will go mainly to soy and corn producers, key Trump constituents in an election year.  This amount follows nearly $26 billion in aid already provided to offset losses from the China trade war.  This new funds exceed USDA’s entire discretionary budget request for next year.  The USDA Secretary may allocate the funds as he wishes, with no oversight.

So much for welfare for the rich.

As for the poor, the bill provides

  • About $25 billion for food assistance (domestic food programs $8.8 billion, SNAP $15.8 billion).

This too sounds like a lot but all it does is account for the expected increase in demand from people newly out of work.  It does not in any way increase the amount that individuals and families receive.

How did this happen?  Chalk it up to effective lobbying by agribusiness.

The gains for agribusiness were accomplished, says the Times, by “A small army of groups mounted the fast-moving campaign for aid, including the politically powerful American Farm Bureau Federation and the National Cattlemen’s Beef Association. Joining them were other smaller players representing producers of goods like turkey, pork and potatoes or sunflowers, sorghum, peanuts and eggs.”

Earlier, Politico reported that nearly 50 organizations representing farmers, equipment manufacturers and agricultural lenders sent a letter stating their needs as a result of declining demand from school and restaurant shutdowns and direct-to-consumer sales.

The bill does little to help the folks who most need help.  Anti-hunger groups tried, but failed.

Poor people need to vote.  And organize.

USDA’s infographics on school food purchases

The USDA has produced four infographics on its purchasing practices for school meals.

  • USDA Foods in Schools – This infographic summarizes nationwide USDA Foods purchases including the average cost per pound by food group and the breakdown of total spending and pounds received by food group.
  • USDA Foods in Schools: Summary by Program – This infographic shows a summary of purchases from all three programs: USDA Foods Bulk for Processing, USDA Foods Direct Delivery, and USDA DoD Fresh. It is important to note that the USDA Foods Bulk for Processing section only includes items classified as a bulk product on the USDA Foods Available List.
  • USDA Foods in Schools: State Overview– This infographic shows the average number of products ordered by States and the top five products by dollar value and volume. This infographic also displays the value of food orders by State.
  • USDA DoD Fresh in Schools – This infographic provides an overview of USDA DoD Fresh purchases including a summary of the top five fruit and vegetables received and the total pounds purchased. It is important to note that the items available through USDA DoD Fresh may vary by State.

I took a look at the first one and got stopped cold by this:

Protein?  What’s that?  The answer:  meat, poultry, fish, eggs, peanut butter, and sunflower seed butter.

I also wondered what DoD Fresh was about.  It is an agreement between USDA and the Department of Defense to supply fresh fruits and vegetables to schools.

For school food aficionados, there is much information here in a readily accessible format.  Enjoy!

Weekend reading: History and Ethics of Jewish Food

Aaron S. Gross, Jody Myers, and Jordan D. Rosenblum.  Feasting and Fasting: The History and Ethics of Jewish Food.  New York University Press, 2020. 

This book comes with heavy-duty endorsements: a Foreword by Hasia Diner, and an Afterword by Jonathan Safran Foer.

I was interested to read it and did a blurb for it.

Feasting and Fasting is a fascinating account of the history of Jewish food, within and outside of dietary laws.   The authors engage in Talmudic debates about how specific foods and diets as a whole do or do not define Jewish identity.  Crisco is for Jews?  Peanut oil caused such debates?  Who knew.  This book is a great read.

What to quote?  So many choices.  Here’s a snippet from Jordan Rosenblum’s chapter on Jews and garlic:

After the Exodus from Egypt, when the Israelites wandered in the desert, they grew tired of eating only manna.  Comparing the varied diet that they ate as slaves in Egypt to the unvaried diet that they now enjoyed as free women and men, a few troublemakers complained: “The riffraff in their midst felt a gluttonous craving; and then the Israelites wept and said, “If only we had meat to eat!  We remember the fish that we used to eat free in Egypt, the cucumbers, the melons, the leeks, the onions, and the garlic.”

This, as it turns out, is the only mention of garlic in the Hebrew Bible.  In this chapter,

we shall briefly explore the historical association between Jews and garlic that develops over the next three millennia.  In doing so, we shall see how garlic eventually functions both internally (by Jews) and externally (by non-Jews) as a symbol that represents Self and Other—or, in the terminology favored in anthropology and food studies, how garlic operates as a metanym for Jews.

Industry-funded study of the week: Walnuts

Replacing Saturated Fat With Walnuts or Vegetable Oils Improves Central Blood Pressure and Serum Lipids in Adults at Risk for Cardiovascular Disease: A Randomized Controlled‐Feeding Trial.  Alyssa M. Tindall, et al. Journal of the American Heart Association. 2019;8:May 7, 2019.

Conclusions: “Replacing saturated fatty acids (FAs) with 57 to 99 g/d of walnuts for 6 weeks reduced central diastolic blood pressure compared with a diet similarly low in saturated FAs but with lower α‐linolenic acid content…This study represents a feasible food‐based approach for replacing saturated FAs with unsaturated FAs (including α‐linolenic acid) from walnuts and vegetable oils, demonstrating that relatively small dietary changes can reduce cardiovascular risk.

Funding: This study was funded by the California Walnut Commission…The California Walnut Commission provided funds for the research conducted. The commission’s staff was not involved with any aspects of conducting the study, analyzing the data, or interpreting the results reported in this article.

Comment: Walnuts, like pretty much all other nuts and seeds, contain healthy fats and other nutrients.  When substituted for unhealthier foods, they would be expected to demonstrate improvements.  This study contributes no new information and there is only one reason to do it: marketing (as I discuss in Unsavory Truth).  The California Walnut Commission wants you to eat more walnuts.  Trade associations or producers of pecans, macadamia nuts. pistachios, almonds, peanuts, hazelnuts, and any other nut you can think of have the same goal.  Do they all have to do this kind of research?  Apparently so.

Mixed nuts, anyone?

Snackification: a new word in my vocabulary

BakeryAndSnacks.com’s Special Edition: Snackex 2019 introduces the concept of “Snackification,” which as far as I can tell is the conversion of three square meals a day to all-day snacking.  Alas, snacks have calories; the more snacks the more calories consumed.  And most are ultra-processed, the term used to describe foods that are best consumed in small amounts.   The more snacks consumed, the happier the snack-food industry will be.  Hence: the push.
