The study: Potato ingestion is as effective as carbohydrate gels to support prolonged cycling performance.  Salvador AF, et al.  J Applied Physiology, 17 October 2019.

Conclusion: “Potato and gel ingestion equally sustained blood glucose concentrations and TT [time-trial] performance. Our results support the effective use of potatoes to support race performance for trained cyclists.”

Funder: The Alliance for Potato Research and Education, “a not-for-profit organisation funded by the potato industry in the US.”

Comment:  I learned about this study from an article in NutraIngrendients.com: “Powered by potato? Spuds ‘just as good’ as carb gels for athletic performance, says study.”

Despite my previous correspondence and interview with the editor of NutraIngredients, the article failed to mention the study’s industry sponsor.

This was especially disappointing because its sister publication, FoodNavigator.com, covered the same study but quoted the funding statement.

The study’s title and result should have triggered a look to see who paid for it.  Really?  Cyclists are supposed to carry potatoes with them to eat on long races?   Why would anyone other than potato sellers even think of such a thing?

Addition: But see comments from readers…

I was interested to hear this from Courtney Puidk, a dietitian:

Love your industry updates – BUT actually using potatoes as fuel has been a thing with cyclists for a long time. I have several friends and an ex who used baked potatoes as fuel during bike races and triathlons because potatoes are 99% glucose so they shoot through you fast, and they have lots of potassium and sodium so act as natural electrolytes. They fit nicely into the pockets of cycling jerseys and/or water bottle holders. And they’re cheap! Not to mention a whole food fuel source over some pricey, marketed sugar gel with lots of packaging.  Plenty of reasons to use potatoes as fuel!

And Simone Braithwaite, a reader from Australia, writes:

A friend of mine recently did the Comrades Marathon in South Africa. She has now done the 100km twice – once for each direction. Funny thing is, on the course the provided energy source is boiled potatoes (with salt). Runners actually carrying boiled potatoes along as they trudge this arduous race, apparently nibbling/sucking as they go.  In this developing world context I actually thought this was excellent as potatoes are an affordable and accessible food source for all. I also wondered how long this tradition would last – before multinationals got in with their ‘superior’ ultra processed products. Maybe this is one case where this study will be most useful!!!?

OK.  I concede.

Jennifer Gaddis.  The Labor of Lunch: Why We Need Real Food and Real Jobs in American Public Schools.  University of California Press, 2019.

This book is a welcome addition to the growing library of works focusing on labor in the food system.  This topic deserves attention and Gaddis is looking at the plight of an especially neglected group, the people who make and serve food to kids in schools.   Unlike any other school program, the USDA-managed National School Lunch—and Breakfast—Programs are expected to be self-supporting through payments by parents and federal reimbursements.  They are chronically underfunded and issues of cost matter far more than food quality.

Gaddis lays out the issues in her introduction:

The NSLP [National School Lunch Program] operates largely as a social welfare program for low-income families and a public subsidy for large-scale factory farms and processed-food companies.  Since the 1970s and the widespread embrace of neoliberal political and economic projects, the pursuit of cheap food, cheap labor, and cheap care has pushed millions of middle- and upper-middle-class families out of the NSLP.  They pursue seemingly “better” algternatives for their own children, but in so doing they fail to hold Congress, the US Department of Agriculture (USDA), and Bg Food companies accountable for the quality of the NSLP…[This] inadvertently reduces political will to invest in an NSLP that provides high-quality food and care for all children and families. [p. 4]

The story she tells here is not pretty—it is one of contempt for the poor coupled with protection of big business, along with lack of political will and weak civil society demand.

Her advice: organize, mobilize, advocate!

One of the great ironies of this advice is that the School Nutrition Association, which represents food service workers, opposes advocacy for better quality food, in part as Gaddis explains, because it has been captured by the processed food industry.

Let grass-roots advocacy begin!

The industry newsletter, FoodNavigator-Asia did a special edition on the food business in the Arabian Middle East:

Plant proteins for dogs?  I’ve written about this before, but now there’s more.

Contrary to prevailing rumor, dogs are well documented to be able to digest grains.  Whether grains are optimal for dogs is another matter and I sure wish we had some decent research on the question.

What we do have is pet-food makers scrambling to sell pet foods to owners convinced that grains are bad for their dogs.  These products are often made with proteins extracted from peas and lentils.

The FDA has gotten reports that dogs fed such pet foods have developed a form of heart disease called  Canine Dilated Cardiomyopathy (DCM). 

The FDA is investigating whether grain-free pet food could be linked to DCM, and it posts the data on reported cases online.  

When the FDA asks owners what dogs with DCM ate, this is what it finds.

Not displayed here are cases of DCM among dogs eating standard commercial pet food.  Those are listed here.

What causes DCM and why so many cases are associated with plant proteins is not known.  One hypothesis is deficiency of taurine (synthesized from sulfur-containing amino acids) in pea and lentil proteins, but adding taurine to diets does not seem to help.

Pea and lentil farmers have complained to the FDA that its warning is hurting their business.  Pet Food Industry reports that sales of grain-free pet foods have declined since the FDA announcement.

The author of a 2016 book about obesity in pets and conflicts of interest in the veterinary nutrition community, who is also the founder of a plant-based pet food company thinks that plan-based ingredients have nothing to do with this.

While the arguments are raging and the FDA continues investigating, what to feed your pet?

Basic advice (from my book with Malden Nesheim, Feed Your Pet Right,” which is actually an analysis of the pet food industry):

• If you are using commercial foods, make sure they say they are “complete and balanced” and have been tested at some point.
• If you are cooking for your pet, make sure your recipe includes the needed nutrients (we give generic recipes in the book)
• Know that no evidence exists that expensive pet foods are better than cheap ones (that research has never been done)
• Vary the products you use.  Variety, balance, and moderation work just as well for pets as they do for people.
• Most important: do not overfeed.  Calories count!

Food crime is a new term in my lexicon.  I’m used to hearing it called food fraud or intentional adulteration.

As I learned from reading an article in Food Safety News, the Food Standards Agency in Great Britain established a National Food Crime Unit in the wake of the 2013 horsemeat scandal.

Examples of food crime include the use of stolen food in the supply chain, unlawful slaughter, diversion of unsafe food, adulteration, substitution or misrepresentation of food, and document fraud…Members of the public and those working in the food and drink sector can speak up about food crime through Food Crime Confidential.

The agency says it focuses on seven types of food crime:

• theft – dishonestly obtaining food, drink or feed products to profit from their use or sale
• illegal processing – slaughtering or preparing meat and related products in unapproved premises or using unauthorised techniques
• waste diversion – illegally diverting food, drink or feed meant for disposal, back into the supply chain
• adulteration – including a foreign substance which is not on the product’s label to lower costs or fake a higher quality
• substitution – replacing a food or ingredient with another substance that is similar but inferior
• misrepresentation – marketing or labelling a product to wrongly portray its quality, safety, origin or freshness
• document fraud – making, using or possessing false documents with the intent to sell or market a fraudulent or substandard product

The unit is not particularly forthcoming about its findings.  According to FoodManufacture.com, it took a freedom-of-information request to discover that the unit received 1193 reports of food crime in 2018, and 364 in the first three months of 2019.

The FOI request was filed by the Chartered Institute of Procurement and Supply, which reports these figures but does not seem to have a formal report online.

Bottom line: Food crime is the highest it has been in the UK since 2013.

The study: Matthews LG, Smyser CD, Cherkerzian S, Alexopoulos D, Kenley J, Tuuli MG, et al. (2019) Maternal pomegranate juice intake and brain structure and function in infants with intrauterine growth restriction: A randomized controlled pilot study. PLoS ONE 14(8): e0219596.

The findings (my emphasis): “There were no group differences in brain injury, metrics or volumes. However, treatment subjects displayed reduced diffusivity within the anterior and posterior limbs of the internal capsule compared with placebo. Resting state functional connectivity demonstrated increased correlation and covariance within several networks in treatment subjects, with alterations most apparent in the visual network in per-protocol analyses. Direct effects on health were not found.

Conclusion: In conclusion, maternal pomegranate juice intake in pregnancies with known IUGR was associated with altered white matter organization and functional connectivity in the infant brain, suggesting differences in brain structure and function following in utero pomegranate juice exposure, warranting continued investigation.

Funding: This work was supported by National Institute of Health Grants R01 HD29190 (D. M. Nelson), K02 NS089852 (C.D. Smyser), U54 HD087011 and P30 HD062171 (T.E. Inder), The Foundation for Barnes-Jewish Hospital (D. M. Nelson) and an unrestricted gift to Washington University School of Medicine from POM Wonderful, Los Angeles, CA. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

Comment: This is a classic example of interpretation bias.  Studies of bias associated with industry funding find that it shows up mostly in the framing of the research question or in the interpretation, as this one demonstrates.  The study did not find anything significant but concluded that drinking pomegranate juice during pregnancy is good for the growing fetus.

Bottom line: Fruit juices (of any kind) are good for health as long as volumes are small.  Eating the fruit itself is better–less sugar, more fiber.

I’ve been seeing lots of books about meat lately.  Here are two recent ones.

Josh Berson.  The Meat Question: Animals, Humans, and the Deep History of Food.  MIT Press, 2019.

The author is an Australian social scientist, a vegan, who has produced a deep dive into the history of the use of meat as food and as cultural symbol.  As he puts it,

The aim of this book is to unpack what I’ve come to call the Meat Question–Should humans be eating meat, and if so who, and what kinds, and how much?–in the most comprehensive way possible.  The perspective…is deep deep in that it encompasses the history of human meat eating and human relationships with other gregarious vertebrates over a span of more than 2 million years.  (p. 2)

This [book’s] perspective is centered on my conviction that the economic violence of meat has less to do with who can and cannot afford it than with how meat serves to prop up a system of asymmetric benefits from all forms of human activity, not just that related to food.  Growing demand for meat is not simply an outcome of growing affluence.  It is a symptom of the inequality and oppression that have accompanied that affluence. (p. 294)

Benjamin Aldes Wurgaft.  Meat Planet: Artificial Flesh and the Future of Food.  University of California Press, 2019.

This book examines the brand-new industry creating lab-based meat.  These products are not yet on the market but are of such enormous public and economic interest that they are well worth book-length treatment.

This book tells the story of what I found, and what I did not find, in the course of my time in the small, strange world of cultured meat, during what seemed to be the early years of an emerging technology.  I expected to spend time in laboratories…This did happen in some measure, but for the most part I found myself with very little laboratory science to observe and a great many public conversations about cultured meat to participate in and sort through.  (p. 15)

But cultured meat, too, raises moral questions.  Not questions about our moral regard for harvested cells, but questions about the implications cultured meat may hold for our moral regard for animals….It is relatively easy to see how cultured meat would or would not suit different philosophical arguments for animal protection….But assuming that cultured meat leads to abolition of animal agriculture, it will change our sense of what these creatures, these nonhuman animals, are doing in the world. (p. 133)

Both of these books deal with the moral, philosophical, cultural, historical, and socioeconomic implications of meat-eating, although from quite different perspectives.

No lab-based meat or dairy product is yet on the market, but lots of people are working on such things.  Here are some recent examples, starting with my favorite.
