Industry-funded study of the week: pet food!

I have a long-standing interest in pet food (see Feed Your Pet Right, and Pet Food Politics: The Chihuahua in the Coal Mine) and in conflicts of interest in research (see Unsavory Truth: How Food Companies Skew the Science of What We Eat).  Knowing of both, a reader, Teresa Reinhardt, alerted me to this one.

The study:  Investigation of diets associated with dilated cardiomyopathy in dogs using foodomics analysisCaren E. SmithLaurence D. ParnellChao-Qiang LaiJohn E. Rush & Lisa M. FreemanScientific Reports volume 11, Article number: 15881 (2021).

Purpose: to identify specific pet food ingredients associated with Dilated Cardiomyopathy (DCM) in dogs.

Methods: Metabolomic profiling of 25 diets associated with canine DCM and 9 diets not associated with DCM.

Results: “Four diet ingredients distinguished the two diet groups (peas, lentils, chicken/turkey, and rice). Of these ingredients, peas showed the greatest association with higher concentrations of compounds in 3P/FDA diets [the ones associated with DCM].“

Funding:  “This work was funded in part by Nestlé Purina PetCare and the Barkley Fund. This work was funded in part by United States Department of Agriculture project number 8050-51000-107-00D, and this entity had no part in the design of the experiments, in the collection, analysis and interpretation of data, nor in composing the manuscript.”

Conflicts of interest: “In the last 3 years, Dr. Freeman has received research funding from, given sponsored lectures for, and/or provided professional services to Aratana Therapeutics, Elanco, Hill’s Pet Nutrition, Nestlé Purina PetCare, P&G Pet Care (now Mars), and Royal Canin. In the last 3 years, Dr. Rush has received research funding from, given sponsored lectures for, and/or provided professional services to Aratana Therapeutics, Boehringer Ingelheim, Elanco, IDEXX, Nestlé Purina PetCare, and Royal Canin. None of the other authors has any competing interests to declare.”

Comment:  DCM is a common heart disease affecting dogs, with a prevalence that exceeds 50% in some breeds (e.g., Doberman Pinschers). More than 1100 cases have been reported to the FDA.

Despite endless speculation, its cause is unknown.  Much attention has focused on one or another dietary deficiencies or specific components (e.g., grains).  As the authors explain:

The diets reported to be associated with DCM often are marketed as “grain-free” and often contain certain ingredients that became part of commercial foods relatively recently (e.g., pulses, potatoes, and sweet potatoes) and lack others (such as rice or corn). Most of the ingredients that are included in the associated diets are also found in human diets, but dogs often eat them in even higher quantities because most dogs eat a single commercial pet food, rather than a variable mixture of multiple foods as humans do.

I think there three issues need further discussion.

(1)  Grains. Some pet owners believe that dogs should not eat grains. They buy pet foods that do not contain them.  This study identified grains only in the pet foods that were not associated with DCM.  Ms. Reinhardt also sent a link to a commentary from someone who questions this finding and raises other critical points about the study.  Dogs are fully capable of digesting grains and grains have been used safely in pet foods for decades.  The FDA describes the association of DCM with on its website.  What’s needed to resolve the peas question is a long-term (years, not months) trial of diets with and without peas.  The pet food industry has no incentive to pay for something like that.

(2)  The funding effect Nestlé Purina PetCare [no relation] paid for the study, and two of the authors consult widely for pet food companies.  Grains are inexpensive pet food ingredients and it is to Nestlé’s interest to have evidence demonstrating that grains do no harm.  How much influence did this company have over the research?  The conflict of interest statement is oddly worded.  The USDA funder is stated to have stayed out of the study, but the statement does not seem to apply to Nestlé, suggesting company influence.

(3)  Pet food research funding in general.  This study had some USDA funding, but government funding for pet food research is rare.  Most pet food research is funded by pet food companies, and most focuses on taste preferences.  Remarkably little research is designed to answer questions about which diets are better than others—a big issue because most pets eat commerical pet foods designed to take care of their complete nutritional needs.

This study identified peas as most strongly associated with DCM.  Pea protein is a main ingredient in plant-based meat alternatives.  It would be good to know more about the dietary effects of peas and pea proteins.

If nothing else this study demonstrates why pet food research matters.  We only have one food system, and pet food is very much a part of that system.

The latest on pet food politics

­­­My most recent collection of items.

  • Pets in Europe88 million households own pets, thereby creating an enormous market for pet foods.
  • Pets in the U.S.:  Pre-pandemic, there were 77 million dogs and 58 million cats, at least those that can be counted.
  • Global market for pet food:  it’s estimated at $75 billion.
  • People love pets:  If anyone in the pet food industry still needed proof that humanization of pets was the foundation for the market’s ongoing growth, consider this: Results of a recent study show that the dietary routine of owners was among the top three reasons for why consumers chose certain types of dog food, particularly grain free.
  • Pets and the Covid-15:  Cats and dogs might have gained the “Covid 15,” but new data reveals a pet obesity epidemic existed long before quarantine.
  • Insects are the hot new ingredient in pet foodsInsect protein demand in pet food may be 165k tons by 2030.
  • Raw pet foods are still a source of toxic Salmonella: A study on a deadly E. coli outbreak in the United Kingdom linked to raw pet food adds to the evidence of such products being a risk factor for human infections, according to researchers. In August 2017, four people were infected with related strains of Shiga toxin-producing E. coli (STEC) O157:H7. One person died after developing the… Continue Reading
  • The FDA frequently recalls or withdraws pet foods: Recalls – of which there are three types – are actions taken by a firm to remove a product from the market. Recalls may be conducted on a firm’s own initiative, by FDA request, or by FDA order under statutory authority.

And one long read:

Nestlé admits 70% of its products are junk foods

I always like writing about Nestlé, the huge multi-national food company based in Switzerland, because it gives me the opportunity to explain that no, I am not related to it (although colleagues have suggested that I claim to be the black sheep of the family).

Judith Evans, writing in the Financial Times, had a big story about the company (behind a paywall but can also be read at the Irish Times site).

Its headline: “Nestlé says majority of its food portfolio is unhealthy.”  She based her story on a leaked internal document.

Nestlé, has acknowledged in an internal document that more than 60 per cent of its mainstream food and drinks products do not meet a “recognised definition of health” and that “some of our categories and products will never be ‘healthy’ no matter how much we renovate”….Within its overall food and drink portfolio, some 70 per cent of Nestlé’s food products failed to meet that threshold [a rating above 3.5 under Australia’s health star rating system], the presentation said, along with 96 per cent of beverages – excluding pure coffee – and 99 per cent of Nestlé’s confectionery and ice cream portfolio.

Because infant formula, pet food, coffee, and the health sciences products were not counted in this analysis, the data apply to about half of Nestlé’s €84.35 billion ($102.6 billion) total annual revenues—Nestlé is indeed Big Food.

I was interviewed for this story, and quoted:

Marion Nestle (no relation), visiting professor of nutritional sciences at Cornell University, [*] said Nestlé and its rivals would struggle to make their portfolios healthy overall.

“Food companies’ job is to generate money for stockholders, and to generate it as quickly and in as large an amount as possible. They are going to sell products that reach a mass audience and are bought by as many people as possible, that people want to buy, and that’s junk food,” she said.

“Nestlé is a very smart company, at least from my meetings with people who are in their science [departments] . . . but they have a real problem . . . Scientists have been working for years to try to figure out how to reduce the salt and sugar content without changing the flavour profile and, guess what, it’s hard to do.”

[*]  Oops.  That should have been Professor Emerita at NYU.  I asked for a correction and thought I had gotten one, but maybe only in the Financial Times.

I was also interviewed by Margarita Raycheva at IHS Market Connect(formerly Food Chemical News, and also behind a paywall):

Marion Nestle says labeling systems fail to account for ultraprocessed foods

While Nestlé’s plans to improve nutritional profiles have sparked some hope in nutrition experts like Hercberg, at least one other leading expert remains skeptical. According to Marion Nestle, a leading nutrition expert and professor at New York University, successful efforts to improve nutrition would have to go beyond meeting thresholds set through label ratings.

“What is at issue in this discussion is whether a somewhat healthier option is a better choice or even a good choice,” Nestle told IHS Markit on Monday (June 1).

While label-rating systems may flag some nutrients of concern, they do little to reduce consumption of ultraprocessed foods, which have been linked to both obesity and chronic disease, Nestle noted.

“NutriScore gives points for less sugar and salt, even to foods that are still ultraprocessed, and so do other nutrient-based front-of-package labeling systems, making all of them gameable by taking off a gram or two,” she said.

“Calling for reduction of consumption of ultraprocessed foods is much simpler, but it would exclude most of Nestlé’s products, even with tweaks,” she added.

The Swiss food giant has confirmed it will update its nutrition and health strategy after British newspaper the Financial Times published leaked internal documents acknowledging that nearly 70% of its main food and drinks products, making up about half of Nestlé’s CHF92.6bn total annual sales, do not meet a “recognised definition of health” and that “some of our categories will never be healthy”…. Read more

No matter how much Big Food companies say that want to promote health and wellness, they can only do so if their products continue to make the same kids of profits as do ultra-processed junk foods.  The company knows this and got caught saying so in public.

As for the uncounted other half of this company’s revenues? I’m keeping an eye on pet food.  Pet Food Industry reports that Nestlé is investing 1 billion yuan in pet food manufacturing in China.

Some musings about pet foods

Pet foods may seem unrelated to food politics but they constitute a vital part of the food system  For one thing, they use up a large part of the byproducts of human food production that would otherwise be wasted.

They also are big business.  The US pet foods brought in $99 billion in sales in 2020.

Nestlé (no relation) is one of the largest pet food producers.  As Quartz puts it, Nestle’s big bet on pet food is paying dividends during the pandemic.

A beloved animal friend for you means big business for Nestle. According to an earnings report released today, the Swiss company reported 3.5% organic growth so far in 2020, and 4.9% growth in the third quarter, its highest level of quarterly growth in the past six years…its pet food brand, Purina PetCare, was a main contributor in each of the company’s global markets, growing 10.6% so far this year, CFO Francois-Xavier Roger said on a call for investors.

To my great amusement, pet food marketing closely follows current food fads.  Why am I amused?  Dogs don’t care what they eat, but their humans do.

  • Cell-based meat for pets: A handful of startup companies are using cell-based meat in pet food, a large market now supplied by food-bearing animals; one uses cells from mice for cat food and cells from rabbits for dog food. (Modern Farmer)
  • Unleash the Power of Postbiotics in Pets:  Pet parents continue to turn towards natural foods, recognizable ingredients, and supplements. As this trend and purchasing pattern continues, we see another ingredient category emerge – Postbiotics.  Read more

And we now have insect-based pet foods.

Pet food safety is an ongoing issue, particularly from Salmonella contamination.  What interested me about this particular recall—Billy+Margot Wild Kangaroo and Superfoods Recipe Dog Food—was its main ingredient, wild kangaroo, and that it is being marketed as a superfood (no such thing exists).

If you have purchased Billy+Margot Wild Kangaroo and Superfoods Recipe in a 4 lb bag, with lot code V 07 Feb 2022 from any retail store nationally, please stop feeding the product to your dogs, dispose of this product immediately, wash your hands accordingly, and sanitize affected surfaces.

Weight loss in dogs and owners:  If one loses weight, the other does too!

My ongoing interest in this topic is a result of having written two books about pet foods:

  • Pet Food Politics: The Chihuahua in the Coal Mine (2008)—an account of the pet food recalls of 2007 and their implications for the health of dogs and cats, but also for the FDA, food safety policy in the United States and China, international food trade, and the pet food industry itself.
  • Feed Your Pet Right (with Malden Nesheim, 2010)—an examination of the booming pet food industry—its history, constituent companies, products, and marketing practices.

The latest pet food recalls: a food safety system issue

A decade ago, I wrote or co-authored two books about pet food (Pet Food Politics: The Chihuahua in the Coal Mineand Feed Your Pet Right).  Why?  Pet foods are part of the US food system, not only because they are a good use of the waste products of human food production, but also because if there are problems with pet foods you can bet that similar problems will occur in production of foods for humans.

The FDA has a web page where it tracks recalls and market withdrawals of pet foods.  To search for pet food recalls, you need to filter for Animal and Veterinary.  This shows that there have been five product recalls in March 2021 alone, four of them because of possible Salmonella contamination.

The largest is of products from Midwestern Pet Foods.  This recall is especially noteworthy for the length of the list of recalled products.

These involve multiple products in each of several brands:

  • Earthborn Holistic
  • Meridian
  • Pro Pac
  • Sportmix
  • Unrefined
  • Venture
  • Wholesomes

Midwestern Pet Foods issued a press release explaining what happened and what needs to happen.

The recall was as the result of a routine sampling program by the company which revealed that the finished products may
contain the bacteria.
Retailers and distributors should immediately pull recalled lots from their inventory and shelves. Do not sell or donate the
recalled products. Retailers are encouraged to contact consumers that have purchased the recalled products if the means
to do so exists.
Do not feed the recalled products to pets or any other animals. Destroy the food in a way that children, pets and wildlife
cannot access them. Wash and sanitize pet food bowls, cups and storage containers. Always ensure you wash and
sanitize your hands after handling recalled food or any utensils that come in contact with recalled food.

On its website, Midwestern Pet Foods says:

At Midwestern Pet Foods, we’ve been feeding pets for generations. We’re a family-owned business now in our fourth generation. Over the years, we’ve learned a lot about family, pet companions and making high-quality pet food & treats. We still have those same Midwestern values that Grandpa Nunn had back in 1926!

If Salmonella is in or on pet foods, there has been a breakdown in food safety procedures.  Salmonella does not usually make pets sick, but it does sicken their owners.  This particular recall demonstrates the same problem I wrote about in Pet Food Politics: one manufacturer makes lots and lots of different products.  Recall information does not always get to individual pet foods stores.  It’s best to keep up with what the FDA is posting.

Caveat emptor.

Pet Parents: Go easy on “Treat Love.”

I subscribe to Obesity and Energetics Offerings because it’s a great way to keep up with current research and commentary on just about anything related to diet and activity.

One of the things I particularly like about it is its section called “Headline vs Study.”

Here is its most recent example:

The headline, from Pet Food Industry magazine (an  unusually well written and edited source of information about this industry), refers to a survey of veterinarians done by Hill’s Pet Nutrition, a maker of pet foods.

According to veterinarians, more than 71% of pet professionals say the pandemic has impacted the way pets eat…Since the start of Covid-19, one third (33%) of pet parents with an overweight pet say their pet became overweight during the pandemic…veterinarians state that only 12% of pet parents proactively flag concerns with their pet’s weight. Moreover, nearly two in three veterinarians say pet parents act surprised (64%) or defensive (64%) upon learning about their pet’s weight issues.

Pet parents?  You know who you are.

What is this about?

IRONICALLY, TOO MUCH “TREAT LOVE” DURING THESE DIFFICULT TIMES IS THE MAIN CULPRIT.

Treats, as Mal Nesheim and I explain in our book about the pet food industry, Feed Your Pet Righthave calories, and those calories—just like the ones from any snack—add up.

Obesity in pets does just what it does in humans; it raises the risk of chronic disease, especially type-2 diabetes

A new study just out in the BMJ, which compared obesity in dogs to that of their owners, says:

Data indicated that owners of a dog with diabetes were more likely to develop type 2 diabetes during follow-up than owners of a dog without diabetes. It is possible that dogs with diabetes could serve as a sentinel for shared diabetogenic health behaviours and environmental exposures.

Pet parents: Walk those dogs!  Love them some other way!

Cheery thought for the weekend: my pet food book

Thanks to Nate Goldstein (@drnategoldstein), Mitchell Davis (@kitchensense), and the adorable Milo for this photo, discovered in my Twitter feed (@marionnestle).

Milo: Don’t eat my book!

OK, it’s ten years old, out of date, and out of print.  Mal Nesheim and I badly want to do an updated edition with a title that better reflects what the book is about.  It’s really an analysis of the pet food industry and what it produces.  We did include generic recipes for feeding dogs and cats, though, so you can make your own .

Anyone interested in taking on this project?  Let me know @marionnestle.
