Industry-funded study of the week: plant-based meat alternatives

Plant-Based Meat Analogs and Their Effects on Cardiometabolic Health: An 8-Week Randomized Controlled Trial Comparing Plant-Based Meat Analogs With Their Corresponding Animal-Based Foods. Toh DWK, Fu AS, Mehta KA, Lam NYL, Haldar S, Henry CJ. Am J Clin Nutr. 2024 Jun;119(6):1405-1416. doi: 10.1016/j.ajcnut.2024.04.006. Epub 2024 Apr 8.

Erratum in: Am J Clin Nutr. 2024 Aug;120(2):459. doi: 10.1016/j.ajcnut.2024.06.012.

This study compared effects on cardiometabolic health among people eating meat or plan-based alternatives for 8 weeks.

Conclusion: An 8-wk PBMA (plant-based) diet did not show widespread cardiometabolic health benefits compared with a corresponding meat based diet.

Funding: This study was supported by Pinduoduo Incorporated (HongKong Walnut Street Limited). Pinduoduo Incorporated had no role in study design, study conduct, laboratory analyses, data collection, management and interpretation or the writing, reviewing and approval of the manuscript.

Comment

This study was sent to me by a reader, who viewed it as a rare example of an industry-funded study with results unfavorable to the sponsor’s interests.  He thought the “Walnut” in the company’s name indicated a plant-based bias.

I wasn’t so sure and wondered what Pinduoduo did, exactly.

According to Wikipedia, “Pinduoduo Inc. (Chinese拼多多Pinyin: Pīn duōduō) is a Chinese online retailer with a focus on the traditional agriculture industry. The business is the largest product of PDD Holdings, which also owns the online marketplace Temu.”

But it gets even better.  The American Journal of Clinical Nutrition published a correction to the paper:

The original funding statement was insufficiently elaborated and has been revised for greater clarity: Christiani Jeyakumar Henry [the senior investigator on this study] reports partial financial support provided by Pinduoduo Incorporated (HongKong Walnut Street Limited) which is an agricultural research firm.

This, then, is a standard example of an industry-funded—and conducted—study producing just the results wanted.  Another example of marketing research, alas.

Cultured meat: of great interest, still not on market

Cell-Based or Cultured Meat continues to generate predictions, positive (new products, new approvals, growth) and negative (doom, bans).

Current status: The FDA and USDA have approved sales of cell-cultured chicken but the only place selling it is Bar Crenn in San Francisco (where I have not been).

While waiting for it to get scaled up (if this ever will be possible), here are a few items I’ve collected recently.

The latest developments on the cultivated meat front

I’m trying to keep up with what’s happening with cultivated meat.  So far, the FDA has approved a couple of cultivated chicken cell companies, and these are selling “chicken” in a couple of restaurants, one in San Francisco and the other in Washington DC.

The big issue: scaling cell production up enough to have product to sell.  It takes lots of cells–billions? trillions?—to make a portion big enough to eat.

Here’s what’s going on in this area in the U.S. and U.K.

Annals of cell-cultured meat: woolly mammoth meatballs?

My son Charles, who lives in Los Angeles, sent me this gem from the L.A. Times: “The woolly mammoth is back — in the form of a meatball.”

A woolly mammoth meatball has been created from the animal’s DNA — 4,000 years after the beast went extinct.

The dish is made of cultured meat, grown in labs from animal cells. It used the DNA of the woolly mammoth, together with fragments of DNA from an African elephant, which is the animal’s closest relative still alive today.  Vow, the Australian company that created the food...said it hopes that the project will challenge people to reassess the climate damage caused by cows and other livestock.

I knew you would want to know about this.

Keeping up with cell-based cultured meat

I don’t know about you but I’m riveted by what’s in the pipeline for cell cultured meat alternatives.   Here are some recent items I’ve been collecting.

Products under development

State of the industry

State of the techno-food scene

Comment

Cell-based meat, meat-plus-algae, and pet food are not yet on the US market so it’s too early to see what they taste like and how well they will do.  I see these products as mostly about mergers, acquisitions, and generating lots of money for investors, which is why I included the Soylent event (Soylent is a nutrient supplement drink, but I put it in the same category of “techno-food”).

Impossible Foods picks a public fight with a reporter

When I saw this tweet from Tom Philpott, I knew immediately what it was about.

I had seen Deena Shanker’s investigative report in Bloomberg News, not least because I’m quoted in it: Fake Meat Was Supposed to Save the World. It Became Just  Another Fad.

The article’s subtitle: “Beyond Meat and Impossible Foods wanted to upend the world’s $1 trillion meat industry. But plant-based meat is turning out to be a flop.”

And then I saw this ad in the January 22 New York Times.

Anonymous Reddit writers saying things like “I suspect it’s coming form [sic] a news outlet paid money to write an article by people who make money from meat sales.”

A badge of honor for Deena Shanker indeed.  Clearly, she hit a nerve.

Meat alternatives still have their fans and I’m not ready to write off fake meat just yet.   But this ad makes me much less sympathetic to this particular Cause.

Ironic addition, January 30: Impossible Foods to lay off 20% of its staff.

My latest update on plant-based meat and dairy substitutes

Much is happening in the plant-based food sector.  I love trying to keep up with it.

First, the bad, or somewhat bad, news:

Next, the new product launches:

And where the industry might be headed:

Comment: Despite the current drop in sales, I don’t see these products disappearing off the shelves.  There is a demand or them among people who do not want to eat meat or dairy foods for reasons of health, animal welfare, or the environment.  The products need to taste good if they are going to continue to sell.  And they need to become more food-based rather than ingredient-based if they are to overcome concerns about their meeting definitions of ultra-processed.

I will keep following this sector with great interest.  Stay tuned.

Industry-funded study of the week: a rare negative outcome

Beyond Meat is taking a beating these days, and this study only adds to its  woes.

Assessing the effects of alternative plant-based meats v. animal meats on biomarkers of inflammation: a secondary analysis of the SWAP-MEAT randomized crossover trial.  Crimarco A, Landry MJ, Carter MM, Gardner CD.  J Nutr Sci.  2022;11:e82.  doi:10.1017/jns.2022.84

Abstract: Alternative plant-based meats have grown in popularity with consumers recently and researchers are examining the potential health effects, or risks, from
consuming these products…the purpose of this work was to conduct a secondary analysis of…a randomised crossover trial that involved generally healthy adults eating 2 or more servings of plant-based meats per day for 8 weeks (i.e. Plant phase) followed by 2 or more servings of animal meats per day for 8 weeks (i.e. Animal phase). Results of linear mixed-effects models indicated only 4 out of 92 biomarkers reached statistical significance. The results were contrary to our hypothesis, since we expected relative improvements in biomarkers of inflammation from the plant-based meats.

Conflicts of interest: “Gardner [the senior author] received gift funding from Beyond Meat which was used to conduct the original research study.”

Comment:  This is a follow up to the original research, which I wrote about previously.  That study found a positive result:

A diet that includes an average of two servings of plant-based meat alternatives lowers some cardiovascular risk factors compared with a diet that instead includes the same amount of animal meat…This study found several beneficial effects and no adverse effects from the consumption of plant-based meats.

The investigators tested the effects of substituting Beyond Meat for animal meats on 92 biomarkers of inflammation.  They found hardly any to be improved by the Beyond Meat substitution.

This disappointed the investigators but I’ll bet it disappointed Beyond Meat even more.

This study was not specifically funded by Beyond Meat.

This work was supported by Stanford University’s Precision Health and Integrated Diagnostics Center (PHIND) and in part by a training grant from the NIH National Heart, Lung, and Blood Institute [T32 HL007034].

It is consistent with the overall observation that industry-funded research tends to find results favorable to the sponsor’s interest; independently funded research can go either way.  See my book, Unsavory Truth, for details and references.

Thanks to Stephen Zwick for sending this one.
