Conflicted study of the week: mushroom patents?

A reader in Norway, Marit Kolby, sent me this one.

First, the press release: “Mushroom consumption may lower risk of depression.”

New research led by Penn State College of Medicine also reveals that these superfoods may benefit a person’s mental health.  Penn State researchers used data on diet and mental health collected from more than 24,000 U.S. adults between 2005 and 2016. They found that people who ate mushrooms had lower odds of having depression.

The study: Mushroom intake and depression: A population-based study using data from the US National Health and Nutrition Examination Survey (NHANES), 2005–2016Djibril M.Ba. XiangGao, LailaAl-Shaar, Joshua, E.Muscat, Robert B.Beelman, John P.RichieJournal of Affective Disorders, Volume 294, 1 November 2021, Pages 686-692.

Hypothesis: “We hypothesized that mushroom consumption is associated with a lower risk of depression in American adults.”

Method: Analysis of dietary recall data from NHANES vs. self-reported depression.

Conclusion: “Mushroom consumers had a lower odd of depression. However, we did not observe a dose-response relationship.”

Funding: none.

Declaration of competing interest: none.

Comment: Ordinarily, beyond noting the conditional “may be linked” (which also could be “may not”  and the lack of dose-response, I would not bother to comment on this study except that Marit Kolby wrote:

As usual, the health effects (this time from mushrooms) are greatly exaggerated, especially given the study type and the lack of a dose-response relationship.  One compound in mushrooms suggested to explain the association is ergothioneine. The authors list no conflicts of interest.  But look at the patent list of the author Beelman.

This called for a look at the patent list.  Beelman does indeed hold several patents related to ergothioneine from mushrooms, but most of them are assigned to the Penn State Research Foundation.   This is not unusual for universities, but called for a look at Penn’s State’s policy on faculty intellectual property.

Penn State’s policy on patents requires research faculty to negotiate patent income according to a formula.

  1. PSRF [the foundation]: 40%
    Inventor(s): 40%
    Administrative Unit of College: 20%
  2. The inventors’ portions of the income are divided according to the contribution percentage that the inventors establish. A memo to establish the percentages to be paid to each invention will be sent to the Inventors before making payment .

Without knowing the details of Beelman’s arrangement with the university, it is difficult to be sure that a conflict of interest exists (he might have turned all the proceeds over to the university), but this situation clearly gives the appearance of a conflict, and an undisclosed one at that.

If professor Beelman is entitled to any percentage of profits from the patents, he has a competing interest and should have disclosed it.

Regardless, his declaration should have acknowledged his patent ownerships, as should the university’s press release.

Are mushrooms a “superfood” as the press release maintains?

Marit Kolby thinks it is more likely that mushrooms are an indicator of usual consumption of whole rather than ultra-processed foods, and points out that a couple of studies have linked ultra-processed foods themselves to depression.

The “Thanksgiving” cookie price index and farmer’s share

I cannot resist sharing information from a press release I received from sweetspotpr.com about something called The Christmas Cookie Price Index.

This comes from a study computing the cost of cookie ingredients in 60 US cities and 30 countries (People do this things?  Apparently, yes).

The main results:

  • The most expensive place to bake Christmas cookies in the US is San Diego, California at $12.40 per batch, followed by Burlington, Vermont ($12.08) and Los Angeles, California ($11.41).
  • Charleston, South Carolinais the cheapest place in the US to bake Christmas cookies at $2.23 per batch, followed by Charleston, West Virginia ($2.90) and Des Moines, Iowa ($4.13).
  • Sweden is the most expensive country to bake Christmas cookies ($12.83), followed by the Dominican Republic ($11.74),Denmark ($10.97), New Zealand ($10.57), Russia ($9.81) and Switzerland ($9.75).
  • Ecuador is the cheapest place to bake Christmas cookies at $3.50 per batch, followed by Poland ($3.62),Spain ($3.80), Germany ($4.04) and Chile ($4.20).

I didn’t think this could wait until Christmas.  I knew you would want to know this in time for Thanksgiving.

And from the National Farmer’s Union,

 

Enjoy the day and the weekend!

FoodPolitics.com will be back on Monday after the Thanksgiving holiday break.

Bored with the thanksgiving menu? Try insects!

FoodNavigator-USA, one of the newsletters I subscribe to, has a special edition on edible insects.  

If you want to know what the food insect industry and market look like these days, this is a great place to get the big buggy picture in a hurry:

And how about some migratory locusts?

The Dietary Guidelines as a marketing opportunity

You might think of the Dietary Guidelines for Americans as federal nutrition advice about how to eat healthfully but to some food companies it’s a marketing opportunity.

FoodNavigator-USA.com writes that the new guidelines for children under age 2 are a “treasure map” for Gerber, a leading baby food manufacturer.

the guidelines underscore the need for products that help babies consume sufficient iron, vitamin D and other nutrients of concern, safely introduce potential allergens, cut back on added-sugar, and cultivate diverse palate preferences to ensure healthy dietary preferences and reduce the risk of picky eaters later.\nInnovative, iron-enriched products need to boost consumption.

How does this work?

One of the main messages in the Dietary Guidelines is to provide infants and young children with sufficient iron.

Gerber to the rescue!

All you have to do is “feed children two servings of infant cereal a day.”

I still vote for feeding kids real food….

Industry-funded study: plant sterols

This one was sent to me by Sara Henriques Martins, a nutritionist from Portugal.

She writes: “I came across an interesting study about the effects of phytosterols on lowering blood cholesterol  which was funded by Danone, a company that sells Danacol, a drink that is sold with this exact purpose.”

The study: Phytosterols, Cholesterol Control, and Cardiovascular Disease.    Andrea Poli, Franca Marangoni, Alberto Corsini, Enzo Manzato, Walter Marrocco, Daniela Martini, Gerardo Medea,  Francesco Visioli.  Nutrients. 202113(8), 2810; https://doi.org/10.3390/nu13082810

Method: “A panel of experts with diverse medical and scientific backgrounds was convened by NFI—Nutrition Foundation of Italy—to critically evaluate and summarize the literature available on the topic, with the goal of providing medical doctors and all health professionals useful information to actively govern the use of phytosterols in the context of plasma cholesterol control.”
Conclusion: “Functional foods or supplements containing phytosterols are effective in controlling plasma LDL cholesterol levels if used appropriately.  These products must be taken on a daily basis.”
Funding: “The preparation of this paper has been made possible by an unrestricted grant from Danone S.p.A. The sponsor had no role in the preparation and finalization of the manuscript, and in the decision to publish it.”
Conflicts of Interest: “A.P. and F.M. are the Chairman and Head of Research, respectively, of NFI—Nutrition Foundation of Italy, a non-profit organization partially supported by Italian and non-Italian Food Companies. All other authors declare no conflict of interest associated with this publication.”
Comment: Danone does indeed make Danacol, a yogurt-based phytosterol supplement.  Such supplements, when taken daily, have been associated with cholesterol reduction for years.  In 2009, for example, at Danone’s request, the European Food Safety Authority assessed the research on Danacol and concluded that “a cause and effect relationship has been established between the dietary intake of phytosterols and lowering of LDL-cholesterol.”  The Nutrition Foundation of Italy has so many industry members that it can be considered an industry front group.  Food products containing phytosterols are available in the United States, but tend to be more expensive than comparable products without phytosterols, and it’s not clear whether consuming them lowers blood cholesterol enough to reduce heart disease risk.  Danone, obviously, would like to sell more Danacol.  Hence: its grant to this group.

Weekend reading: in defense of eating beef

Nicolette Hahn Niman.  Defending Beef: The Ecological and Nutritional Case for Meat (revized and expanded second edition). Chelsea Green, 2021. 

The Defending Beef cover

This is an updated edition of Hahn Niman’s 2014 book, which I wrote about in October that year.  Then, it was titled Defending Beef: The Case for Sustainable Meat Production.

I did a blurb for the book when it first came out and it still holds for this new edition:

Issues related to the long-term health effects of red meat, saturated fat, sugar, and grains are complex and I see the jury as still out on many of them.  While waiting for the science to be resolved, Hahn Niman’s book is well worth reading for its forceful defense of the role of ruminant animals in sustainable food systems.

In my 2014 post, I said:

The subtitle says it all: “The Manifesto of an Environmental Lawyer and Vegetarian Turned Cattle Rancher.”

Really?

Really.  She’s not kidding.

As [my blurb] might suggest, I have a more cautious interpretation of the science she summarizes, but there are plenty of reasons why eating meat can help improve human nutrition, especially when the animals are raised as humanely and sustainably as possible, which the Nimans most definitely do on their beautiful Bolinas ranch. [Photos are here]

Vegetarians: does she convince you?

Let the debates begin.

Well, 7 years later the new edition focuses much more on arguments about the effects of beef production on climate change and whether plant-based meat alternatives are worth the trouble.

The big news:  Hahn Niman is no longer a vegetarian.

I may once have believed that if I followed a vegetarian diet, nothing would have to die for my meals.  I now see how wrong I was…My primary mission these past two decades has been helping, in whatever ways I can, build a more environmentally sound, nourishing and humane food system.  We have a long way to go.  I don’t urge people to eat meat.  But I certainly don’t urge refraining from it, either.  I encourage omnivorous eaters to seek well-raised meat.  Abandoning meat will not positively affect the food system and may diminish one’s health.  The greatest consumer impact will come from people who eat meat actually buying it from good sources. (p.244)

I am with her on all of that.

That meat has nutritional and ecological benefits is beyond dispute.  This books lays out her point of view about the reasons for these benefits in an especially thoughtful way that carefully considers the counter-arguments.

Whether you agree with her views or not, this is the book to read about these issues.

What about 100% fruit juice?

An additional observation in the fruit drink study I recently discussed was a reduction in purchases of 100% juice, probably because it is so hard to tell the difference without careful scrutiny of labels (hint: look for 100%).

100% juice is a better option than fruit drinks because it has a better balance of nutrients and no added sugars. But it is still sugary because so many pieces of fruit go into it [really, fruit is the best option].

The orange juice industry is worried about decreasing sales.

The worldwide market for juices is increasing.

The juice industry would like it to grow even faster.

I was interested to see juice marketing materials emailed to dietitians.

Want to take a guess as to who paid for these messages?

Hot summer temperatures combined with a population eager to get outside and get moving means risk of dehydration is high. In addition to water, consider including 100% juice as a healthy, nutrient dense beverage option. In addition to rehydration and increasing fruit intake, two new studies show 100% juice has many other health benefits.

  1. A recent UK study published in Nutrients found moderate consumption of 100% fruit juice, which aligns with the US Dietary Guidelines, does not increase the risk of obesity, type 2 diabetes, cardiovascular disease or poor glycemic control. Furthermore, regular daily consumption of 100% juice, may confer health benefits related to vascular function and reduced blood pressure. Emerging evidence shows there may even be a positive impact on cognitive health. [Funding: This research was funded by an unrestricted grant from the Fruit Juice Science Centre].
    [Funders: a consortium of orange producers, juice manufacturers and packaging companies based in Europe and Brazil under the umbrella of the European Fruit Juice Association (AIJN)].
  1. A second review study, published in Frontiers in Immunology, found that citrus juice, contains key nutrients and bioactive substances that help our immune system to work efficiently and reduce inflammation. [Funders: a consortium of orange producers, juice manufacturers and packaging companies based in Europe and Brazil under the umbrella of the European Fruit Juice Association (AIJN)].

Juice drinks: it’s all about the marketing

Fruit drinks, as opposed to 100% fruit juice, are a no-brainer.  They are heavily sugar-sweetened, and best consumed in very small amounts or not at all.

They are difficult to distinguish from 100% fruit juice.  Their labels make them look fruity and juicy.

So do their ingredient lists:

But these are juice concentrates and require translation: added sugars.  In this case, 11 out of the 13 grams per serving.

Public health advocates want to discourage parents from buying sugary beverages for their kids.  Here are the results of one such attempt.

As the accompanying editorial, Warning: Don’t Let the Beverage Industry Harm Your Kids, explains, 

Unlike general social marketing or other communications campaigns, countermarketing is designed “to reduce the demand for unhealthy products by exposing the motives of their producers and portraying their marketing activities as outside the boundaries of civilized corporate behavior”…Let’s put this good news to use by placing responsibility at the feet of the platforms and companies profiting from directly and incessantly targeting children with marketing the food and drink they should avoid.

If you would like to know how this works, here’s a toolkit for campaigns against fruit drinks.

One additional observation was a reduction in purchases of 100% juice, probably because it is so hard to tell the difference without careful scrutiny of labels (hint: look for 100%).
