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.

Mexico’s terrific new dietary guidelines. Yes!

Mexico has issued new dietary guidelines.

https://www.gob.mx/cms/uploads/attachment/file/826673/Gui_as_Alimentarias_2023_para_la_poblacio_n_mexicana.pdf

  1. Breastfeed babies for the first 6 months and then continue until age 2 along with other nutritious foods.
  2.  Eat more vegetables and fruits.
  3. Eat beans.
  4. Choose whole grains.
  5. Eat less beef and processed meats.
  6. Avoid ultra-processed foods.
  7. Drink water.
  8. Avoid alcohol.
  9. Be physically active.
  10. Enjoy meals with family and friends.

I’m looking forward to reading a case study on how the public health institute got these through the political process.

If people follow these guidelines, these industries will be in trouble:

  • Infant formula
  • Beef
  • Processed meats
  • Ultra-processed foods
  • Sugar-sweetened beverages
  • Alcohol

People will be healthier!  These industries will also be in trouble.

  • Pharmaceutical drugs
  • Private medicine
  • Insurance companies? (you might think they would benefit, but they make so much money on illness—this one is complicated)

I hope the new U.S. Dietary Guidelines will find these inspiring.

Weekend reading: front-of-pack labels

Center for Science in the Public Interest is campaigning for mandatory front-of-package labeling—like these.

Here’s what you need to know about the campaign:

  • Comment from CSPI responding, point-by-point, to industry arguments opposing mandatory front-of-package labeling
  • Sign-on comment filed in support of CSPI’s front-of-package labeling petition
    • Signatories include American Heart Association, American Cancer Society Cancer Action Network, American Public Health Association, Consumer Federation of America, Consumer Reports, and more
  • Comment filed in response to FDA’s proposal to conduct quantitative research on front-of-package labeling
  • Factsheet summarizing the importance of mandatory front-of-package labeling in the U.S. (from January)
  • Factsheet summarizing findings of a public opinion poll commissioned by CSPI in March (we found widespread support for mandatory front-of-package labeling)

Guess what!  The food industry opposes this kind of labeling.  A lot.

Why?  Because it might discourage purchase of ultra-processed junk foods.  That, after all, is its point.

The 2025-2030 Dietary Guidelines: an update

Personally, I can’t believe we are going through this again since the result will certainly not differ much from previous versions, except in details (see my previous post on this).
But here we are, so let’s get to it.

ODPHP must be in charge this round (leadership passes back and forth between ODPHP and USDA’s nutrition policy office).  It says:

You can get involved by:

  • Attending virtual meetings: View the recording of the first meeting held in February 2023, and register to view the livestream of the second meeting on May 10th on DietaryGuidelines.gov.
  • Providing public comments: Comments may be submitted online.
  • Subscribing to email updates: Stay informed on each step of the process by registering for updates.

More details on the Dietary Guidelines development process can be found at DietaryGuidelines.gov.

What to expect?

  • Investigative reports on conflicts of interest among members of the Dietary Guidelines Advisory Committee (members must report conflicted interests but the agencies do not make the reports public)
  • Nothing about sustainability (Off the table; the agencies said there will be a separate report on that.  When?)
  • Nothing about meat (Off the table)
  • Debates about the significance of ultra-processed foods (but only with respect to heart disease)
  • Other issues, surely

My prediction: after an enormous amount of work, the guidelines will say, as they mostly do:

  • Balance calorie intake with expenditure
  • Eat more plant foods (foods)
  • Don’t eat too much salt, sugar, saturated fat (nutrients)
  • And, if we are lucky, minimize or avoid ultra-processed foods

Stay tuned.

The Lancet series on commercial determinants of health (and, therefore, nutrition)

Executive Summary

Commercial actors can contribute positively to health and society, and many do, providing essential products and services. However, a substantial group of commercial actors are escalating avoidable levels of ill health, planetary damage, and inequity—the commercial determinants of health. While policy solutions are available, they are not currently being implemented, and the costs of harm caused by some products and practices are coming at a great cost to individuals and society.

A new Lancet Series on the commercial determinants of health provides recommendations and frameworks to foster a better understanding of the diversity of the commercial world, potential pathways to health harms or benefits, and the need for regulatory action and investment in enterprises that advance health, wellbeing, equity, and society.

  • Defining and conceptualising the commercial determinants of health: Anna B Gilmore, Alice Fabbri, Fran Baum, Adam Bertscher, Krista Bondy, Ha-Joon Chang, Sandro Demaio, Agnes Erzse, Nicholas Freudenberg, Sharon Friel, Karen J Hofman, Paula Johns, Safura Abdool Karim, Jennifer Lacy-Nichols, Camila Maranha Paes de Carvalho, Robert Marten, Martin McKee, Mark Petticrew, Lindsay Robertson, Viroj Tangcharoensathien, Anne Marie Thow

Although commercial entities can contribute positively to health and society there is growing evidence that the products and practices of some commercial actors—notably the largest transnational corporations—are responsible for escalating rates of avoidable ill health, planetary damage, and social and health inequity; these problems are increasingly referred to as the commercial determinants of health. The climate emergency, the non-communicable disease epidemic, and that just four industry sectors (ie, tobacco, ultra-processed food, fossil fuel, and alcohol) already account for at least a third of global deaths illustrate the scale and huge economic cost of the problem. This paper, the first in a Series on the commercial determinants of health, explains how the shift towards market fundamentalism and increasingly powerful transnational corporations has created a pathological system in which commercial actors are increasingly enabled to cause harm and externalise the costs of doing so….

Most public health research on the commercial determinants of health (CDOH) to date has focused on a narrow segment of commercial actors. These actors are generally the transnational corporations producing so-called unhealthy commodities such as tobacco, alcohol, and ultra-processed foods….Moving forward, it is necessary to develop a nuanced understanding of commercial entities that goes beyond this narrow focus, enabling the consideration of a fuller range of commercial entities and the features that characterise and distinguish them…Improved differentiation among commercial actors strengthens the capacity of practitioners, advocates, academics, regulators, and policy makers to make decisions about, to better understand, and to respond to the CDOH through research, engagement, disengagement, regulation, and strategic opposition.

This paper is about the future role of the commercial sector in global health and health equity. The discussion is not about the overthrow of capitalism nor a full-throated embrace of corporate partnerships. No single solution can eradicate the harms from the commercial determinants of health—the business models, practices, and products of market actors that damage health equity and human and planetary health and wellbeing. But evidence shows that progressive economic models, international frameworks, government regulation, compliance mechanisms for commercial entities, regenerative business types and models that incorporate health, social, and environmental goals, and strategic civil society mobilisation together offer possibilities of systemic, transformative change, reduce those harms arising from commercial forces, and foster human and planetary wellbeing. In our view, the most basic public health question is not whether the world has the resources or will to take such actions, but whether humanity can survive if society fails to make this effort.

Weekend reading: pesticides on produce

The Environmental Working Group has just published its annual lists of Dirty Dozen and Clean Fifteen.

  • The Dirty Dozen—those with the highest levels of harmful pesticides:  Strawberries, spinach, kale/collards/mustard greens, peaches, pears, nectarines, apples, grapes, peppers, cherries, blueberries, green beans.
  • The Clean Fifteen—those with the lowest levels of harmful pesticides: Avocados, sweet corn, pineapple, onions,papaya, sweet peas (frozen), asparagus, honeydew melon, kiwi, cabbage, mushrooms, mangoes, sweet potatoes, watermelon, carrots

What always interests me about these lists is how nobody except the EWG wants to deal with pesticides on produce, and how much pushback the EWG gets from industry.

IFIC, the International Food Information Council (an industry front group), criticizes the EWG for promoting “organic produce as being safer and healthier than conventional produce.”  It says (my paraphrase except for direct quotes):

  1. You don’t need to avoid any kind of produce.
  2. Regulators ensure all foods are safe.
  3. Regulators inspect and monitor all foods.
  4. Residues are on all foods but “they are not to be feared.”
  5. “Giving elite status to organic produce is detrimental to people’s health.”
  6. Everybody agrees people need to eat more produce.
  7. “Shelf-stable foods, organic or conventional, present relatiable and healthy foods for all of us.”

My translation: Don’t bother with organics, ultra-processed foods are fine.

The Alliance for Food and Farming (a produce industry trade group) says:

Despite peer reviewed research showing it is scientifically unsupportable and negatively impacts consumers, the so-called “dirty dozen” list will be released soon  This list was developed to invoke misplaced safety fears about fruits and vegetables – the food group we are encouraged to eat more of every day to improve physical and mental health, prevent illness and increase lifespan.

This group says the “Dirty Dozen” recommendations are “unsupportable” and “negatively impact consumers and produce consumption.”

It says,

  • Just wash it! According to the FDA, washing produce under running tap water can reduce and often eliminate pesticide residues, if they are present at all.
  • A farmer’s first consumer is their own family so food safety is always their priority.

Comment: We use a lot of pesticides, more than 400 in the US alone, and more than 2.5 million metric tons annualy, worldwide.

We can debate the degree of harm caused to individuals, especially children, but there is no question they are bad for soil and the environment, and I’ve never heard anything suggesting they are good for us.

We would be better off eating fewer of them and producing food in ways that use less of them.

If EWG pushing farming in that direction, it needs it.

Choose organics as a means to encourage more sustainable production practices (vote with your fork).

Advocate for policies to reduce pesticide use (vote with your vote).

And thank EWG for holding industry’s feet to the fire.

Oh no not again. The 2025-2030 Dietary Guidelines process begins

USDA announced the members of the new 2025 Dietary Guidelines Advisory Committee last week.

It also set up the places where you can:

Why my “oh no not again?”

I was on the Advisory Committee for the 1995 Guidelines, have followed them closely since 1980, and have written about them repeatedly in Food Politics but also more recently on this site.

  • Reason #1.  They don’t change enough from one edition to another to have to go through all this fuss.  The 1980 Guidelines said eat more vegetables and fruit; balance calories; and eat less saturated fat, salt, and sugar.  As did the current Guidelines.  Want to make a bet?  The new ones will too.
  • Reason #2:  The committee no longer gets to do much.  When I was on the committee, we chose the research questions, reviewed the research on them, and wrote the Dietary Guidelines.  We did it all.  This committee will only review the research.  The agencies have already chosen the research questions (as I explained previously).  The agencies will write the guidelines.
  • Reason #3: The Dietary Guidelines get longer, more complicated, and more obfuscating every year.  The original ones came as a 24-page small pamphlet.  They’ve been expanding ever since.  The most recent is 149 pages online.
  • Reason #4: What they say has to be a result of political compromise.  The last time USDA was in charge, Congress instructed the Secretary not to allow any discussion of diet and sustainability.  As if it didn’t matter.

Well, here we go again.  Let’s wish the committee the best of success.  Here’s its chance to say something about ultraprocessed foods (not mentioned in the current version), clarify the meat situation, insist on taking environmental issues and sustainability into consideration, and giving clear, unambiguous advice about diet and health.  Enjoy!

  • Previous Editions of the Dietary Guidelines are here.
  • How they are developed is here.
  • Online historical documents related to the Guidelines are here.
