Weekend reading: the ironies of drinking fluid milk

Anne Mendelson.  Spoiled: The Myth of Milk as Superfood.  Columbia University Press, 2023 (396 pages).

 

I am an admirer of Anne Mendelson’s books and did a blurb for her Chow Chop SueyBut this one is over the top—original, compelling, brilliantly written.

Driving this book is a question I’ve not heard asked before, at least not so directly: Why and how did the consumption of fresh liquid milk (“drinking-milk”)—as opposed to fermented dairy products—become framed as a nutritional necessity?

Her question derives from some basic facts about cow’s milk and its industrial production:

  • Once cow’s milk leaves the udder, it is easily contaminated with pathogenic bacteria.
  • Most adults have stopped making the enzyme that digests the sugar lactose in milk and can’t drink it without getting unpleasant digestive systems.
  • To produce milk safely requires complicated and expensive industrial processes.
  • The cost of milk production exceeds the price people are willing to pay for it; dairy farming is a losing proposition even with taxpayer subsidies.
  • Industrial milk production is hard on cows and pollutes the environment.

Why are we even doing this?  For this, she blames 19th and 20th century European and American doctors who thought the ability to digest lactose normal, nutritionists (calcium!), and the USDA (3 servings a day!).

She is not against eating dairy foods when they are fermented.  These, yogurt and the like, are much safer.  Friendly bacteria split the lactose along with producing acid that destroys pathogens.

You don’t have to agree with all her points to appreciate how well they are argued.

To wit:

[The book] argues that influential nutritional theories about fresh and fermented milk took a disastrously wrong turn in the eighteenth century.  The reason is that the founders of modern Western medicine had no way of understanding the genetic fluke that allowed them, unlike most of the world’s peoples, to digest lactose from babyhood to old age.  In other words, today’s mega-industry stemmed from a lack of scientific perspective.  That lack turned the one form of milk that is most fragile, perishable, difficult to produce on a commercial scale, and economically pitfall-strewn into a supposed daily necessity for children and, to a lesser extent, adults.  [pp x, xi].

No other food product is as staggeringly difficult and expensive to get from source (in this case, a cow) to destination (milk glass on table) in something loosely approximating its first condition.  If one existed, it would be treated as an astounding luxury. [p. 1].

Mendelson takes deep dives into the history of dairy use, dietary recommendations, industrial production, and government dairy policy.  In attempting to teach about the Farm Bill, I was defeated by Milk Marketing Orders, the formulas used by the government to set price support levels required to be paid by “handlers” (milk processors) to dairy producers in different areas of the country.  I could not find anything about this in the index, alas, but I loved what she says about them on page 205.

These formulas gradually became as abstruse, and as unintelligible to anyone outside a small charmed circle, as anything in the bad old days before the federal government stepped in.  Far from abolishing the buyer’s market, they trapped farmers selling fluid milk within the marketing order system in endless struggles to wring enough out of handlers to recoup production costs….What I do understand is that as the postwar era advanced, the sheer incomprehensibility of producer-handler milk price schemes again became an endless frustration to dairy farmers, above all those trying to make a living within the marketing order system for drinking-milk.

One final irony:

Nothing is going to dislodge supermarket drinking-milk from its towering economic importance.  It is certain to continue along the track of expansion, consolidation, and increasingly complex technological infrastructure that it has pursued for almost three quarters of a century.  Big Milk is going to become Bigger Milk.  Its absurdities are also sure to become more entrenched.  The greatest of these is the plain fact that Americans are drinking less milk while dairy farms are producing more of it.

A personal comment: The book triggered a memory.  I once visited a school lunch program in Barrow (now Utqiaġvik), Alaska.  Inuit children were served the standard USDA lunch, which requires half-pint cartons of milk.  I did not see any of them drinking it.  The untouched cartons were discarded.  The milk was not only culturally inappropriate, but wasteful.  All food in that part of North Alaska has to be flown in on airplanes.

How to sell plant-based products: Use red packaging?

The headline got my attention: New study finds meat eaters are more willing to try plant-based products when packaged in red.

This e-mailed press release came from ProVeg International, a German “food awareness organisation with the mission to replace 50% of animal products globally with plant-based and cultivated foods by 2040.”

A groundbreaking new report released by ProVeg International, titled, “The Power of Colour: Nudging Consumers Toward Plant-Based Meat Consumption,” reveals key insights into the hidden influence of colour on people’s perceptions of a plant-based product’s flavour and appeal. Remarkably, simply using appealing colours in product packaging has the power to reshape consumer behaviour and prompt a shift toward plant-based meat.

Survey participants associated red with good taste,  green with health and eco-friendliness, and blue (their favorite color) with budget consciousness, but also quality.

Food companies go to a lot of trouble to encourage sales.  I knew that package color and design influence sales, but had never seen the research.

In looking at this report, I’m not sure how ProVeg came to these conclusions (this graph shows the most profound differences), but it sure is interesting to see how these things are done.   Enjoy!

USDA’s latest campaign: checkoff-based sandwiches of all things

I received this email from USDA’s MyPlate group:

Hi Marion

MyPlate National Strategic Partners, a group developed by the United States Department of Agriculture (USDA), just announced the launch of a new resource to help Americans build healthier sandwiches! The full press release is below, and I am happy to answer any questions or arrange any interviews!

WASHINGTON, D.C. – January 11, 2024 – As MyPlate National Strategic Partners, the Grain Foods Foundation, Hass Avocado Board, National Association of State Departments of Agriculture Foundation and National Wheat Foundation are excited to introduce a new resource aimed at helping individuals build healthier and more nutritious sandwiches.

Every day, nearly half of all Americans enjoy a sandwich – and most people are not meeting recommendations of the Dietary Guidelines for Americans.[1] The new “Build a Better Sandwich” resource features practical tips to help bridge this gap, with realistic and inspiring ideas for enjoying a variety of grains, lean proteins and fiber-filled fruits and vegetables and low-fat dairy in better-built sandwiches…To download the “Build a Better Sandwich” resource and other materials created by MyPlate National Strategic Partners, please visit https://www.myplate.gov/partner-resources.

[1] Sebastian et al. Sandwich consumption by adults in the U.S.: What We Eat In America, NHANES 2009-2012. Food Surveys Research Group Dietary Data Brief No. 14. Dec 2015.

Given the sponsors, want to take a guess at how you are supposed to make these sandwiches?

I’m all for healthier sandwiches and eating avocados (love them!), but this is an example of the Hass Avocado Board—a USDA-sponsored checkoff (marketing and promotion) program—at work.

Don’t you think it’s odd that the USDA’s doesn’t include a broader range of vegetables or plant foods in its sandwich advice?

This is one of the many things wrong with USDA sponsorship of checkoff programs….

Harmful chemicals in food: recent studies are not reassuring

I don’t say much about potentially harmful agricultural or other industrial chemicals in food for several reasons:

BUT (in capital letters because it is a bit one):

Studies of three chemicals illustrate these problems.

DICAMBA 

What it is: A herbicide used to kill broadleaf weeds that grow in fields of corn, wheat, and dicamba-tolerant soybeans.

Why it’s a worry: It can cause immediate toxic effects and might be carcinogenic.  It is highly volatile and can damage non-target plants through drifting, causing constant complaints from neighboring farmers.  The courts have overturned the EPA’s approval of dicamba use.  Even though the EPA admits dicamba has adverse effects on handlers as well as “birds, mammals, bees (larvae), aquatic plants and non-target terrestrial plants,” it is allowing existing stocks of dicamba to continue to be used.

The recent study: The headline: Alarming levels of weed killer found in study of pregnant women.  The study examined changes in the the number of pregnant women with dicamba in their urine and the amounts excreted from 2020-2012 to 2020-2022.  It found increases in both measures.

Conclusion: “Reliance on herbicides has drastically increased in the last ten years in the United States, and the results obtained in this study highlight the need to track exposure and impacts on adverse maternal and neonatal outcomes.”

PHTHALATES

What these are: Chemicals used to soften polyvinylchloride plastics.

The concern: Phthalates leach into food from plastic packaging materials.  They disrupt endocrine function.

The recent study:  Exposure to phthalates is associated with adverse birth outcomes such as decreased gestational age and increased risk of preterm birth.

Conclusion: “The $1·63–8·14 billion costs of preterm birth described here …add to the disease burden and costs of plastic in the USA, which were recently estimated to be $250 billion annually….Our findings also support individual behavioural interventions to reduce exposure. These include choosing personal care products labelled to be free of phthalates, and replacement of packaged foods with fresh foods.

CHLORMEQUAT

What this is: a plant growth regulator used on wheat, oats, and barley to decrease stem height, making the plants easier to harvest.

Why it’s a worry: Chlormequat has been linked to reduced fertility, altered fetal growth, and delayed puberty in animals.

The recent study: The headline: 80% of Americans test positive for chemical found in Cheerios, Quaker Oats that may cause infertility, delayed puberty.   The study found increasing amounts of this chemical in food and urine samples.

Conclusion: “These findings and chlormequat toxicity data raise concerns about current exposure levels, and warrant more expansive toxicity testing, food monitoring, and epidemiological studies.”

Comment: These are only three of all the chemicals out there that get into our food and appear in our bodies.  Yes, more research is needed to find out just how harmful they are.  But I see no evidence that they are good for us.  I think we need:

  • Much greater urgency and attention from FDA and EPA on getting these chemicals out of the food supply
  • More information about how to avoid the chemicals, especially in pregnant women and young children
  • Coalition advocacy for more stringent regulation (the Environmental Working Group is doing a great job but cannot do this alone)

Industry-sponsored study of the week: a menstruation supplement

The study:  Lactobacillus paragasseri OLL2809 Improves Premenstrual Psychological Symptoms in Healthy Women: A Randomized, Double-Blind, Placebo-Controlled Study. Nutrients. 2023; 15(23):4985. https://doi.org/10.3390/nu15234985

Methods: “This study employed a randomized, placebo-controlled, double-blind, parallel-group design to assess the efficacy of continuous ingestion of OLL2809 [the supplement] for managing menstrual symptoms in healthy women.”

Conclusion: “This study suggests that the consumption of OLL2809 over three menstrual cycles in healthy women can alleviate premenstrual ‘decline in activity’ and ‘irritability’, thereby indicating the potential of OLL2809 to enhance women’s QOL [Quality of Life].

Conflicts of Interest:  All authors are employees of Meiji Co., Ltd. The company funded this research. All authors are the inventors of pending patent (Japanese Patent Application No. 2023-182470).

Comment: The supplement is a bacterial probiotic.  The authors are employed by its maker and hold a patent for it, which they fully disclose.  Just as a reminder, industry-funded studies tend to come out with results favoring the sponsor’s interest, as is certainly the case here.

I need to say something about the journal, Nutrients, since many of the studies I post on industry-funded Mondays appear in that journal.  It charges authors €2900 (about $3300) to publish their articles.  It’s an open-access journal, so all authors have to pay to publish their articles.  More rigorous journals do not usually require page charges from authors unless they want open access.  Nutrients gives me the impression of pay to play.

Does cell-cultured meat have a future? This is not the moment.

I subscribe to AgFunder News, not least because I so admire Elaine Watson’s reporting on the food industry.

I was particularly interested in her detailed account of investment in cultured meat and seafood startups: ​Preliminary AgFunder data point to 78% decline in cultivated meat funding in 2023; investors blame ‘general risk aversion.’

Here’s what’s happening:

Funding may have dropped, but investors put nearly $200 million into this technology in 2023.  That isn’t nothing.

Watson reviews the reasons for the funding decline:

  • High interest rates
  • Risk aversion
  • Too many companies seeking investment
  • Scalability of the product
  • Cost parity
  • Lack of government funding

Cultivated meat is not yet on the market.  It’s hard to assess it or predict its future without tasting it.  I’m trying to keep an open mind.

For a deep dive into what’s happening in this industry, see Joe Fassler’s excellent piece in the New York Times: Opinion | The Revolution That Died on Its Way to Dinner.

His point:  Cell-cultured meat is “an escape hatch for humankind’s excesses.”

For all its terrifying urgency, climate change is an invitation — to reinvent our economies, to rethink consumption, to redraw our relationships to nature and to one another. Cultivated meat was an excuse to shirk that hard, necessary work. The idea sounded futuristic, but its appeal was all about nostalgia, a way to pretend that things will go on as they always have, that nothing really needs to change. It was magical climate thinking, a delicious delusion.

In the course of his investigations, Fassler got to taste cell-cultured chicken.  This did not make him optimistic about its future.

As I said, I’m trying to stay open minded.  I suspect this story is not over yet.  Stay tuned.

USDA updates its plant hardiness zones

I’m on the USDA’s mailing list for press releases and learned that it had updated its map of plant hardiness zones based on the lowest minimum temperature expected over a 30-year average period.

USDA’s announcement of its new hardiness map said “When compared to the 2012 map, the 2023 version reveals that about half of the country shifted to the next warmer half zone, and the other half of the country remained in the same half zone.”

The new map is interactive.  You can click on it to see your zone.  My Manhattan zone is 7b.

It was 6b when I moved here in 1988, meaning that the lowest expected winter temperature was minus 5 to zero degrees F.  The zone is now 5 degrees higher.

My apartment has a terrace on which I grow food and other plants in pots.

I love the rosemary hedges in California and I tried growing rosemary on my terrance.  Until a few years ago, it behaved as an annual and did not survive the winter.

Now it does.

The USDA’s announcement did not mention climate change.

This induced Civil Eats to headline its excellent report on the zoning changes The USDA Updated Its Gardening Map, But Downplays Connection to Climate Change.

It’s not that the USDA doesn’t recognize the role of climate change.  It’s just that its various sub-agencies don’t talk to each other.

I did a little digging and came up with an archived site, Climate Change Pressures in the 21st Century.

This took me to a July 26, 2022 report.

This, in turn, took me to the USDA’s informative 2018 analysis, Assessing potential climate change pressures across the conterminous United States: mapping plant hardiness zones, heat zones, growing degree days, and cumulative drought severity throughout this century.  

In the era of persistent climate change, it is important that we consider how continued perturbations to our climate system may intensify through the end of the century (U.S. Global Change Research Program [USGCRP] 2017). Further, it is important to evaluate these potential changes under alternative scenarios to gauge the potential magnitude of these changes. By focusing on four key metrics related to plant growth and survival, but also of key interest to human well-being, we map and summarize projections of growing degree days, plant hardiness zones, heat zones, and cumulative drought severity across the conterminous United States throughout this century

This report lays out what’s happening now along with predictions for each of those metrics.

For plant hardiness zones, Baseline refers to mean absolute minimum temperature for the 30-year period, 1980-2009.  Early century is 2010-2039.

Here are USDA’s scientists’ low and high estimates—predictions—for mid-century (2040-2069) and late century (2070-2099).

Climate change is occurring much more rapidly than had been predicted.  Look at what’s happening in Alaska, Greenland and Antarctica, for example.

It feels as though New York’s climate is approaching that of what used to be typical for Northern California.

My parsley is already behaving as a perennial and rosemary seems to be doing just fine.

I’m expecting an early spring.

Sunday viewing: Super Bowl food ads

Question of the day: What does a 30-second Super Bowl ad cost?

Answer: roughly $7 million (I’m not kidding—for 30 seconds).

Here is Statistica’s “Average cost of a 30-second Super Bowl TV commercial in the United States from 2002 to 2023.”

I have to confess to not being much of a football fan but I am riveted by the junk food content—and astronomical cost—of Super Bowl ads.

I first learned about this year’s collection from FoodNavigator—USA.

Super Bowl LVIII: The products, ads expected to make big plays during game dayWith the Super Bowl two weeks away, consumers are preparing their grocery lists and budgets for the big game day, as CPG brands ready their ads and promotions with the anticipation of receiving a volume boost the week after the game…. Read more

Here’s its prediction:

When it comes to what consumers will bring to Super Bowl parties, 72% said they will buy chips and dips, 44% pizza, 42% homemade appetizers, 35% side, and 33% pre-made appetizers.

Lesser purchased food items include fruit at 32%, cheese/charcuterie at 27%, and homemade desserts at 27%. Only 6% of consumers said they would bring nothing to a party.

Additionally, 47% of consumers said they are planning on purchasing alcoholic beverages, compared to 27% who said the same for non-alcoholic beverages.

However, 34% of shoppers under the age of 35, a demographic increasingly embracing a sober or sober-curious lifestyle, will be buying alcohol, compared to 72% of the consumers aged 55-64.

OK.  The Super Bowl is an occasion for junk food and alcohol.  Would you believe 1.45 billion chicken wings expected to be consumed during the game?

Brand Innovator lists the advertisers.  Here are some of the food and alcohol advertisers:

  • Budweiser, Bud Light, and Michelob ULTRA
  • Hellman’s Mayonnaise
  • Pringles
  • Doritos
  • Reese’s
  • Frito-Lay
  • Nerds
  • M&Ms
  • Coors Light
  • Popeyes
  • Drumstick
  • DraftKinds
  • Starry
  • Mountain Dew Baja Blast
  • Oreo
  • Molson Coors

Here are some summaries:

Enjoy the game, but watch those calories!

Addition: a reader sent this SuperBowl infographic with much more on its being the #2 eating occasion (after Thanksgiving).
