MyPlate in song?

I am not a big fan of the MyPlate food guide.

  • It was created without doing consumer research to find out how well people understand it.
  • Pie charts are harder to understand than pyramids (the old pyramid, despite its flaws, conveyed the what-you-should-eat messages much better).
  • The Protein section makes no nutritional sense; grains and dairy are also excellent sources of protein, and beans, which are high in protein, are vegetables.

Never mind.  We have to live with it.

It appeared in 2010.  Now the USDA is trying to sell it, and with a catchy music video no less.

Will this sell kids on eating their veggies?

I hope the USDA has an evaluation in the works.

Artificial sweeteners: the backlash

This has not been a good year for artificial sweeteners.

The World Health Organization says don’t use them for weight control and don’t give them to children.

The recommendation is based on the findings of a systematic review of the available evidence which suggests that use of NSS does not confer any long-term benefit in reducing body fat in adults or children. Results of the review also suggest that there may be potential undesirable effects from long-term use of NSS, such as an increased risk of type 2 diabetes, cardiovascular diseases, and mortality in adults.

US Right to Know says: Aspartame: Decades of science point to serious health risks  

And now, researchers say Splenda is not all that great either:
Overall, the toxicological and pharmacokinetic findings for sucralose-6-acetate raise significant health concerns regarding the safety and regulatory status of sucralose itself.
The FDA says the artificial sweeteners on the market are Generally Recognized as Safe at amounts typically used.  These include:
  • Acesulfame potassium (Sweet One, Sunett).
  • Advantame.
  • Aspartame (NutraSweet, Equal).
  • Neotame (Newtame).
  • Saccharin (Sweet’N Low).
  • Sucralose (Splenda).
  • Luo han guo (Monk Fruit in the Raw).
  • Purified stevia leaf extracts (Truvia, PureVia, others)
I was curious to see what the Mayo Clinic made of all this:

In general, it is safest to take in small amounts of sugar substitutes. And it’s best to use sugar substitutes for a short time, or just every once in a while. So try to cut back if you use them a few times a day…In general, sugar substitutes are safe for healthy adults…But artificial sweeteners can help some people enjoy sweetness without excess calories. And if used in moderation, artificial sweeteners can be part of a healthy diet.

How’s that for a clear message?

For me, this issue is a no-brainer.  One of my food rules is not to eat anything artificial, so sweeteners are off my dietary radar.

My advice for anyone else?

  • If you must use them, try to minimize.
  • And don’t give them to kids.

Industry influence of the week: pork

A member of the Academy of Nutrition and Dietetics, the professional association for Registered Dietitian Nutritionists, sent me this emailed announcement from Pork & Partners, a program of the National Pork Board Checkoff.

The accompanying message:

A Friend To All Foods + CPEUs for You!

Pork & Partners is an exciting new community for RDNs, tailored to help you meet your professional needs. Become a Partner to access free CPEU opportunities, fresh lean pork recipes, client resources, research, and so much more. Join today!

CPEUs are continuing professional education units, required for maintaining dietetic registration.   Dietitians usually pay for continuing education.

It’s so generous of the National Pork Board to offer free credits:

Introducing Pork & Partners, your new communityfocused on the needs of nutrition professionals. We’re here to provide free continuing education opportunities, exciting events, featured recipes, evidence-based handouts and peer-reviewed research. Join us to access resources and support to take your practice to the next level.

The Pork & Partners website emphasizes the nutrition, health, sustainability, and cleanliness of pig production.

I couldn’t find anything on the site about confinement of pregnant sows, the subject of a recent Supreme Court decision, or the many lawsuits over offensive odors from pig CAFOs.

Pork producers must not want dietitians talking about such things.  Hence: free CPEUs.

Weekend viewing: Poisoned!

Poisoned: The Dirty Truth About Your Food, a Netflix documentary about food safety in the U.S., premiered at the Tribeca Film Festival and I got to go.

It’s based on the book by Jeff Benedict about the Jack in the Box E. coli O157:H7 poisonings in 1993, and features Bill Marler, the lawyer who represented the families of kids who got sick or died from eating undercooked hanburgers contaminated with that especially toxic form of E. coli.  

I got to go to the premier because I’m in it—one of the many talking heads.

From left to right: Alexa Ginsburg, Associate Producer; Kristen Lazure, Producer; Bill Marler, food safety lawyer and Poisoned star; Ross Dinerstein, Producer; Jeff Benedict, Author of Poisoned; Christine Haughney, Journalist; Sarah Sorscher, CSPI; Me; Darin Detwiler, father of boy who died from eating a Jack in the Box hamburger and food safety advocate; Stephanie Soechtig, Director.

My interview for this was so long ago—prepandemic?—that I had forgotten all about it.  I may be prejudiced but I think the film is terrific.

It really lays out what’s wrong with our food safety system and what needs to be done to fix it.  I thought I knew this stuff pretty well—see my book Safe Food: The Politics of Food Safety—but I learned a lot from it, partly because the photography is so well done.

Some images are unforgettable (spoiler alert):

  • The children hooked up to tubes in hospitals.
  • Their grieving parents.
  • Vast confined animal feeding operations (CAFOs) right next to fields of vegetables.
  • Representatives of the USDA and FDA: “the US has the safest food supply in the world.”
  • Bill Marler saying that he no longer has cases of people sick from eating hamburger since the USDA declared E. coli O157:H7 an adulterant.

It’s really worth seeing.

While waiting for Netflix to schedule it, Marler explains how you can see it on Tribeca at Home.

Innovations in food product development: now we have to deal with AI?

I am indebted to the daily newsletter, Food Navigator Europe, for keeping me up to date on the latest developments in European food marketing.

With all of the fuss at my university about how Artificial Intelligence (AI) is changing the way we live, I was riveted by this article.

Artificial intelligence designs soda for Swiss market: ‘We were gripped by AI fever’

Its subtitle: It took just two days for Swiss beverage company Vivi Kola to develop the artificial intelligence-designed beverage using ChatGPT, Midjourney and Unreal Engine.

AI to make yet another sugary drink?  THIS is what AI is being used for?

Gripped by AI fever, the Vivi Kola team found that by leveraging AI tools, it was able to develop a low-sugar, vegan soda product with health benefits within just two days.

First steps involved asking ChatGPT to develop a vegan recipe using ingredients with known health benefits. The response included water, lime juice, haskap berry juice, ginger juice, chicory root powder, and cane sugar…According to ChatGPT, the drink would be full of antioxidants, strengthen the immune system, promote a healthy gut, and stimulate digestion.

The Vivi Kola team procured the ingredients, combined them, and conducted first taste tests.

Oh great.  Ultraprocessed foods created by AI.  Just what we (don’t) need.

RIP Aero Farms: it just went bankrupt

I, for one, am not surprised, but am also not rejoicing.  Aero Farms has just filed for bankruptcy.

I thought Aero Farms was a valiant experiment in vertical leafy green farming run by some very smart people.

Pre-pandemic, I visited their factory in Newark, New Jersey, a couple of times and fjound the place impressive in concept, size, and production.

The photo can’t show how enormous this factory is, with rows of cloth-covered trays stacked to the high ceiling.  The company planted the greens on cloth and sprayed nutrients on the roots growing through the cloth.  The greens were clean, free of pathogenic bacteria, and surprisingly tasty.  They grew several different kinds, all with distinctive flavors.  All were tested to demonstrate their excellent nutritional value.

They sold the greens to a variety of local restaurants and institutions.

But I am not surprised by their going bankrupt.

I am currently working on an updated edition of What to Eat, in which I discuss food issues, one of them vertical farming.  From my research, I can tell you:

  • The kinds of plants that can be grown in vertical farms are limited to those that need relatively low light (e.g. lettuce); even the best LED lights are not strong enough for more profitable vegetables.
  • Lettuce from California costs half as much to produce as lettuce from East Cost vertical farms.
  • The Achilles heel of indoor farming is the cost of all those lights.  Energy from the sun is free.  Electricity from the grid is anything but.
  • AeroFarms reported $35 million in losses in 2021, but predicted profitability by 2024.

Vertical farming is in trouble unless it can solve the light problem.

Was it worth a try?  That’s for you to decide.

In the meantime, Aero Farms is keeping its Danville, California plant open and remaining optimistic that it can continue to brink in venture capital.

Industry reactions to the news are also not surprising.  Those who follow vertical farming knew this was coming.

I’m truly sorry for this experiment failed.

Cargill is selling its Chinese poultry business to venture capital company

This article in Feed & Grain caught my attention: Cargill intends to sell its poultry business in China to private equity firm DCP Capital, according to reports.

Cargill is the tenth largest broiler producer in the world; it was responsible for the slaughter of an astonishing 625 million broilers last year, of which 49 million were in China.

You don’t hear much about Cargill because it is not publicly traded.  It is family held, but huge:  155,000 employees, annual revenues of more than $134 billion.

It makes that money from food oils, ingredients, grains, oilseeds, cotton, animal feed, and financial services.

According to this article,

Cargill in 2013 inaugurated its integrated poultry operation in Lai’an, Anhui, China, which included every stage of the supply chain: breeding, raising, feed production, hatching, slaughtering and processing…The company also opened a new US$48 million poultry complex in Chuzhou, Anhui, in 2019. That operation included breeding, raising, feed production, hatching and primary and further processing capabilities.

Now, Cargill is selling off its Chinese enterprises to venture capital.

Cargill must think it best to get out of China.

The venture capital company must think money can still be made there.

This, it seems to me, is an example of what is happening to the global food supply.

It is no longer about making sure that people have enough to eat and do not go hungry.

Food is about making money for investors.

That means keeping costs as low as possible, regardless of the effects on health or the environment.

Industry-funded study of the week: meat, the microbiome, and cardiovascular risk

Christina Leffel, a public health nutritionist in Florida, sent this one, which with both find amusing.

The study: Effects of Adding Lean Red Meat to a U.S.-Style Healthy Vegetarian Dietary Pattern on Gut Microbiota and Cardiovascular Risk Factors in Young Adults: a Crossover Randomized Controlled Trial – The Journal of Nutrition.  VOLUME 153, ISSUE 5P1439-1452, MAY 2023, https://doi.org/10.1016/j.tjnut.2023.03.013

Method:  19 participants consumed 3 study diets in random order: 1) healthy lacto-ovo vegetarian diet (LOV); 2) LOV plus 3 ounces/d of cooked unprocessed lean red meat (URM); and 3) LOV plus 3 ounces/d of cooked processed lean red meat (PRM). Measures: Fecal and fasting blood samples.

Results: The addition of unprocessed or processed lean red meats to a LOV HDP did not influence short-term changes in bacterial taxonomic composition.  When the data from all three diets were combined, “changes in some bacteria were associated with improvements in TC, LDL-C, triglycerides, and HDL-C concentrations, and TC/HDL-C ratio.”

Conclusions:  Healthy young adults who adopt an HDP that may be vegetarian or omnivorous, including lean red meat, experience short-term changes in gut microbial composition, which associate with improvements in multiple lipid-related cardiovascular risk factors.

Funding: “The study was cofunded by the Pork Checkoff, North Dakota Beef Commission, Beef Checkoff, and Foundation for Meat and Poultry Research and Education. The supporting sources had no role in study design; collection, analysis, and interpretation of data; writing of the report; or submission of the report for publication.

Author disclosures: “During the time this review was conducted, WWC received funding for research grants, travel or honoraria for scientific presentations, or consulting services from the following organizations: U.S. National Institutes of Health, U.S. Department of Agriculture (Hatch Funding), Pork Checkoff, National Pork Board, Beef Checkoff, North Dakota Beef Commission, National Cattlemen’s Beef Association, Foundation for Meat and Poultry Research and Education, American Egg Board, Whey Protein Research Consortium, National Dairy Council, Barilla Group, Mushroom Council, and the National Chicken Council. Additionally, SRL received funding for research grants, travel or honoraria for scientific presentations, or consulting services from the following organizations: U.S. National Institutes of Health, U.S. Department of Agriculture, National Science Foundation, Showalter Research Trust, Grain Foods Foundation, CP Kelco US, OLIPOP, Inc, Council for Responsible Nutrition. YW, T-WLC, MT, and CMC declare no conflict of interest. The funder and these other organizations had no role in the design and conduct of the study, analysis, interpretation of the results, and writing of the manuscript.”

Comment: This is yet another industry-funded study in which the funder claims no role–a statement that always makes me laugh.  That’s what they all say, despite much evidence that the funding influence in such situations can be considerable, although unrecognized.  For details, see my book, Unsavory Truth: How Food Companies Skew the Science of What We Eat.

The meat industry, apparently, is trying to convince vegetarians that they can eat any kind of meat they want and not affect their cardiovascular risk.  This, of course, contradicts tons of other evidence, including associations with cancer risk.  These risks may not be mediated through the microbiome, however.  What this study says is that if you are worried about the risks of meat, you don’t have to worry that it changes your microbiome much, at least under the conditions of this study.
