Nina Guilbeault.  The Good Eater: A Vegan’s Search for the Future of Food.  Bloomsbury, 2024.

I did a back-cover blurb for this book:

The Good Eater is a vegan sociologist’s remarkably open-minded exploration of the historical, ethical, health, environmental, and social justice implications of not eating meat.  Guilbeault’s extensive research and interviews get right into the tough questions about this movement, leaving us free to choose for ourselves whether to eat this way.

Guilbeault has followed vegan dietary practices (no animal products) for a long time but was troubled by the self-righteousness and proselytizing of many vegans.  As a trained sociologist, she set out to investigate the origins, practices, and effects of vegan diets, through reading but also through interviews with what seems like everyone having anything to do with animal welfare and plant-forward diets.  The result is an exceptionally broad look at the who’s who of veganism, from historical figures to contemporary entrepreneurs and chefs.  The book is well written, rational, and not at all uncritical.

Here’s are a couple of excerpts:

Projections show that to avert environmental disaster by 2050 we need to reduce our meat consumption by at least a third, and by half in North America and Europe…But many people still eat eggs for breakfast and yogurt as a snack, put dairy milk in their coffee, add a slice of ham to their sandwich for lunch, and choose a piece of meat or fish for dinner, all in one day.  A reduction from that daily menu to a couple of eggs and a small piece of meat or fish once a week seems like a hefty drop, yet that is how humanity has eaten for most of our natural history.  (pp 284-285)

I can understand why, for many people, a vegan lifestyle seems unappealing, overwhelming, or even downright offensive.  As we know, meat has played a key part in our cultural and evolutionary history, and habits are notoriously difficult to break.  Veganism requires a shift in identity as well as the embrace of a social category still on the fringe….This is partly because being vegan in a non-vegan world is hard, but also because the vegan movement places an emphasis on moral perfection.  Yet…long-lasting, sustainable change doesn’t come from a place of shame, judgment, and guilt.  It comes from a place of joy and a sense of belonging.  (p 290)

 

Let’s do two at once—studies funded by gthe beef industry.

I.  BEEF AND MUSCLES

I learned about this one from a headline in Food Navigator — Europe’s daily newsletter: Muscle protein synthesis more successful with beef than plant-based protein in older people, study finds

One look at the headline and I wanted to know: Who paid for this?

The study:  Higher Muscle Protein Synthesis Rates Following Ingestion of an Omnivorous Meal Compared with an Isocaloric and Isonitrogenous Vegan Meal in Healthy, Older Adults.  Journal of Nutrition.  2023. DOI:https://doi.org/10.1016/j.tjnut.2023.11.004.

Purpose: Plant-derived proteins are considered to have fewer anabolic properties when compared with animal-derived proteins…So far, no study has compared the anabolic response following ingestion of an omnivorous compared with a vegan meal.

Methods: In a randomized, counter-balanced, cross-over design, 16 older (65–85 y) adults (8 males, 8 females) underwent 2 test days. On one day, participants consumed a whole-food omnivorous meal containing beef as the primary source of protein (0.45 g protein/kg body mass; MEAT). On the other day, participants consumed an isonitrogenous and isocaloric whole-food vegan meal (PLANT).

Results: MEAT increased plasma essential amino acid concentrations more than PLANT over the 6-h postprandial period (incremental area under curve 87 ± 37 compared with 38 ± 54 mmol·6 h/L, respectively; P-interaction < 0.01). Ingestion of MEAT resulted in ∼47% higher postprandial muscle protein synthesis rates when compared with the ingestion of PLANT (0.052 ± 0.023 and 0.035 ± 0.021 %/h, respectively; paired-samples t test: P = 0.037).

Conclusions:  Ingestion of a whole-food omnivorous meal containing beef results in greater postprandial muscle protein synthesis rates when compared with the ingestion of an isonitrogenous whole-food vegan meal in healthy, older adults.

And now to answer my question:

• Conflict of interest:  [two of the authors] received research grants, consulting fees, speaking honoraria, or a combination of these for research on the impact of exercise and nutrition on muscle metabolism. A full overview on research funding is provided at: https://www.maastrichtuniversity.nl/l.vanloon. All other authors report no conflicts of interest.
• Funding:  This study was funded in part by The Beef Checkoff, Denver, USA, and Vion Food Group, Boxtel, The Netherlands….The funders had no role in data collection and analysis, decision to publish, or preparation of the manuscript.

Comment:  The Beef Checkoff is the USDA-sponsored research-and-marketing program which taxes beef producers and uses the funds to promote beef sales.  Maybe the funder had no role as stated, but the checkoff is unlikely to fund research that is not in its best interest.

The meat industry wants everyone to believe that meat is superior to plants, as food, and eating vegan diets is hazardous to health.  Hence, this research.

Something is seriously wrong when it is this easy to guess who paid for a study from its title alone.

II.  BEEF AND  MENTAL HEALTH

Just when I was ready to post that item, I ran across another one.

The study: Meat consumption & positive mental health: A scoping review. Preventive Medicine Reports. Volume 37, January 2024, 102556.

Highlight: “The majority of studies showed no differences between meat consumers and meat abstainers in positive psychological functioning.”

Results: “Eight of the 13 studies demonstrated no differences between the groups on positive psychological functioning, three studies showed mixed results, and two studies showed that compared to meat abstainers, meat consumers had greater self-esteem, ‘positive mental health’, and ‘meaning in life.'”

Conclusion [a positive spin]: “Although a small minority of studies showed that meat consumers had more positive psychological functioning, no studies suggested that meat abstainers did.”

Funding source: This study was in part funded via an unrestricted research grant from the Beef Checkoff, through the National Cattlemen’s Beef Association. The sponsor of the study had no role in the study design, data collection, data analysis, data interpretation, or writing of the report.

Declaration of competing interest: [The first author] previously received funding from the Beef Checkoff, through the National Cattlemen’s Beef Association.

Comment: This review caught my attention because it found a null result: beef eating has no effect on mental health.  This is unusual for industry-funded studies.  But the article contains a positive spin:  some studies do in fact find benefits of beef eating whereas none find this result from not eating beeef.  Make of this what you will.  I think the Highlight says all you need to know.  Industry funding muddies interpretation of research results.  It’s best to avoid taking it.

Conclusions and Relevance  In this randomized clinical trial, we observed cardiometabolic advantages for the healthy vegan vs the healthy omnivorous diet among healthy, adult identical twins. Clinicians may consider recommending plant-based diets to reduce cardiometabolic risk factors, as well as aligning with environmental benefits.

The study has its share of detractors, American Council on Science and Health (ACSH), for example: Stanford Medicine Releases Confirmation Bias Study; Media Takes The Bait.  Its chief criticisms

• The improvements were in biomarkers, not health.
• Both diets were healthy,
• Obviously, diets without cholesterol will reduce cholesterol.
• Vitamin B12 levels were ldeficient on the vegan diet.

Comment: The ACSH is an industry-funded front group.  Low B12 is an easy problem to solve, and vegans, who by definition eat no foods of animal origin, have to make sure they complensate for its absence.

The twin idea is clever and adorable—and the reason for the press attention and for the Netflix documentary.  The study shows that vegan diets improve cardiovascular risk biomarkers in healthy people.  Why not?  This is further evidence for the benefits of largely plant-based diets.

There’s a lot of new product development going on in the plant-forward arena: chocolate, cheese, and anything else you can think of.

Which of these products will survive?  You get to decide that one.

Daily Harvest is a company that makes vegan meals, mostly organic, and freezes them for home delivery.

By mid-June, it had received 470 complaints from customers who ate a new product, French Lentil + Leek Crumbles, but developed severe liver and gall bladder problems.  On June 23,  Daily Harvest issued a recall of the product “due to potential health risk” (also see After 470 reports of illnesses, Daily Harvest recalls French Lentil + Leek Crumbles).

I was especially interested in this event for two reasons: Daily Harvest twice sent me meals to sample (before it introduced this one) and I knew they had to be cooked before eating, which would kill harmful microbes, and I could not imagine what could possibly cause reactions this toxic (as I explained to the New York Times).

This product’s ingredient list seems benign:

organic butternut squash, organic hemp seeds, organic cauliflower rice, organic extra virgin olive oil, organic french lentils, organic red lentils, organic tri-colored quinoa, organic cremini mushrooms, organic tara flour, organic leeks, organic parsley, water, organic cassava root flour, organic flax seeds, organic sacha inchi powder, chia seeds, organic porcini powder, himalayan sea salt, organic apple cider vinegar, organic onion powder, nutritional yeast, organic garlic powder, organic tomato powder, organic white pepper, organic coriander seeds, organic mustard powder, organic thyme.

More than that, on June 25, food safety lawyer Bill Marler was asking the same question: What is it in Daily Harvest’s French Lentil and Leek Crumbles that is causing liver failure?  He was sending samples out to his own labs.

On June 28, Daily Harvest responds to customers sickened, hospitalized from 1 of its products.

On June 30, the FDA published its Investigation of Adverse Event Reports: French Lentil & Leek Crumbles

On June 17, 2022, in response to consumer complaints submitted to the company, Daily Harvest voluntarily initiated a recall of their French Lentil & Leek Crumbles…From April 28 to June 17, 2022, approximately 28,000 units of the recalled product were distributed to consumers in the continental United States through online sales and direct delivery, as well as through retail sales at the Daily Harvest store in Chicago, IL, and a “pop-up” store in Los Angeles, CA. Samples were also provided to a small number of consumers. Daily Harvest emailed consumers who were shipped the affected product, and other consumers for whom the company had contact information and consumers were issued a credit for the recalled product. Consumers who may still have the recalled product in their freezers should immediately dispose of it.

On July 1, the FDA announced the recall and issued an advisory for these events.

Also on July 1,  Daily Harvest issued UPDATES ON OUR VOLUNTARY RECALL OF FRENCH LENTIL + LEEK CRUMBLES

Rachel here – I want to give you another update on the French Lentil + Leek Crumbles recall. As you know, we’ve been conducting exhaustive testing over the course of the last two weeks. Despite this, we still have not identified a possible cause. I am sorry that it’s taking as long as it is to pinpoint exactly what may have made people sick. We are deeply committed to finding answers for those impacted. We’re working with top doctors, microbiologists, toxicologists as well as 3 independent labs.   While additional testing is underway, results to date rule out the following:

• Hepatitis A

• Norovirus

• A range of mycotoxins, including aflatoxins

• Food-borne pathogens including Listeria, E.Coli, Salmonella, Staphylococcus Aureus (Staph), B.Cereus, and Clostridium Species

• Major allergens including egg, soy, milk, and gluten

I assure you, we will not stop until we get to the bottom of this. We’re continuing to work in close cooperation with the FDA, CDC and other health agencies. The FDA released an update on their investigation yesterday, which can be found here on their website.

I’m baffled.  I can’t understand why toxin testing hasn’t come up with anything.  The illnesses are real and all traced to this product.

The FDA’s recommendation: “Consumers should not eat, sell, or serve recalled products. Consumers who may still have the recalled product in their freezers should throw it away.”

Bill Marler agrees with don’t eat it, but he wants the product saved as evidence.  He has questions and suggestions:

• When did Daily Harvest first learn that its French Lentil + Leek Crumbles were causing Liver Failure?
• What to do if you have been or are sick after eating French Leek and Lentil Crumble  

His hypothesis: the Tara ingredient.

• Revive Superfoods no longer has Tara as a listed ingredient – what happened in the last 24 hours?
• Are Revive Superfood Smoothies linked to acute Liver Failure too?
• Is Reddit the new FDA? Is it the Tara?
• Hey, CDC, I have 175 people you should talk to

We believe that the illnesses may well be linked to a common ingredient called Tara that comes exclusively from Peru (this due because it is a unique ingredient to the French Lentil + Leek Crumbles AND to certain Revive Smoothies where people are reporting identical symptoms).

Here’s what Wikipedia says about Tara:

Tara gum…is produced by separating and grinding the endosperm of T. spinosa seeds…The major component of the gum is a galactomannan polymer similar to the main components of guar and locust bean gums that are used widely in the food industry….Tara gum has been deemed safe for human consumption as a food additive… Medicinal uses in Peru include gargling infusions of the pods for inflamed tonsils or washing wounds; it is also used for fevers, colds, and stomach aches. Water from boiled, dried pods is also used to kill fleas and other insects.

Bill Marler is on the case.  He has 175 clients so far.

• Marler Clark files first of hundreds of lawsuits against Daily Harvest
• Daily Harvest customer had gallbladder removed after eating frozen item: suit.
• Daily Harvest hit with lawsuit by woman who blames company for gallbladder removal
• Daily Harvest Faces Lawsuits Over Claims of Mystery Illness Causing Severe Pain and Gallbladder Failure

I’ve heard privately from people who experienced sickness after eating this product.  I’ve read about others like this one:

• Daily Harvest customer tried to warn CEO symptoms much worse than ‘gastrointestinal discomfort’

I wish everyone a speedy recovery, and hope the toxin gets identified soon.  Stay tuned.

My Twitter feed over the Labor Day weekend was full of messages like this one:

It took me a while to figure out what they were talking about, but eventually I was sent a link to a story in Vice about people who became ill on vegan diets. The article quotes me:

“Most healthy people should be able to adapt to an all-plant diet,” says Marion Nestle, nutritionist, professor, and James Beard Award-winning author. She emphasizes eating a “variety of plant food sources, taking in enough calories to maintain a healthy weight, and finding a good source of vitamin B12.”

The article describes the health problems reported by some followers of vegan diets.  It quotes me again:

Nestle notes these problems are more associated with “starvation” than a standard plant-based diet, which “should not cause people to lose weight or have any of those issues.” However, Nestle adds that a diet high in fibrous plants can take time to adapt to, and people who have been advised to eat a low-fiber diet “will have problems eating a wide enough variety of plant foods to meet nutrient needs.” In other words, many of these influencers may be masking disordered eating habits that are unsustainable.

So, in answer to the tweets:

• I am an omnivore.
• I do not endorse vegan or any other kind of diet.
• I believe that many widely different dietary patterns can support good health.
• It is possible, but not always easy, to eat healthfully on a vegan diet.

Healthy diets generally contain a wide variety of relatively unprocessed foods in adequate but not excessive amounts.

There are lots of good ways of doing this.  Enjoy!

A Gallup poll reports the percentages of vegetarians and vegans in America.

• 5% of Americans say they are vegetarians, unchanged from 2012
• 3% say they are vegans, little changed from 2% in 2012

You are more likely to say you are vegetarian or vegan if you are:

• Younger (18-49) rather than older
• Make less than $30,000 a year
• Liberal (11%) rather than conservative (2%)

Want to see how they got these numbers or argue with the results?  The methods are here.

GlobalData, a data and analytics company., says vegan diets will be even more popular in 2018.

• Great Britain: In 2017, 3% self-identified as vegan, compared with 0.8% in 2014.
• U.S.: In 2017, 5.5% self-identified as vegan, compared with 1% in 2014.

GlobalData consumer analyst, Ronan Stafford comments

The rising number of vegans and how fashionable the cuisine now seems to be, big companies are taking notice; the number of vegan options will increase in both supermarkets and restaurants…These trends will combine to make 2018 the best year yet, in which to follow a vegan diet.

Evidence: McDonald’s is going vegan—at least in Sweden and Finland.

The sandwich, which has already been tested at a handful of McDonald’s locations in Finland, consists of a soy patty, bun, tomato, lettuce, pickles, onion, ketchup, mustard, oil and an egg-less sandwich sauce…McDonald’s said the burger will be on its permanent menu in the two countries, a response to “more and more” people wanting to eat “plant-based food” that is better for the environment.

Other evidence:

• Mintel: Nearly 10% of new food launches in Sweden this year were vegan items, according to research firm Mintel. That’s up nearly eight-fold from 2012.
• Nestle: is buying the Sweet Earth, which makes vegan and vegetarian burritos and burgers.
• Euromonitor: Global sales of vegan-labeled foods increased by nearly 8% last year to $12.8 billion.
