The pushback on ultra-processed foods

Ultra-processed foods—defined operationally as industrially produced foods formulated to be irresistably delicious that can’t be made in home kitchens (because you don’t have the machinery or the ingredients—are by now well established to be associated with weight gain and weight-related chronic diseases.

Evidence now suggests the association is causal.  Ultra-processed diets induce people to eat more calories without realizing it.

Alas for food companies.  Ultra-processed products are among their most profitable.

The British Nutrition Foundation to the rescue!

  • It has issued a position statement on ultra-processed foods.   It complains that:
  • The classification system omits foods the Foundation considers healthy.
  • It implies that expensive artisanal products are superior for health (advice to reduce UPF raises questions of equity).
  • The research is largely observational.
  • The food environment is a key driver of poor health.
  • Making products that are not ultra-processed may have unintended consequences.
  • Demonizing ultra-processed foods could foster feelings of guilt and stigma.
  • Messages to avoid UPF might discourage industry from reformulation.
  • Food processing plays a releant role in food system sustainability and food security.

When I read things like this, I have the usual question: Who paid for this?

The British Nutrition Foundation says:

BNF’s funding comes from: membership subscriptions; donations and project grants from food producers and manufacturers, retailers and food service companies; contracts with government departments; conferences, publications and training; overseas projects; funding from grant providing bodies, trusts and other charities.

If it lists its corporate sponsors, I can’t find it.

But PowerBase says:

The British Nutrition Foundation (BNF) is the key food industry front group in the UK. The BNF promotes itself as a source of impartial information, but it does not always make its links with industry clear.

The BNF is hard at work on behalf of food companies who wish the entire UPF concept would just disappear.  See, for example, “How do we differentiate not demonise –Is there a role for healthier processed foods in an age of food insecurity? Proceedings of a roundtable event” published in the Nutrition Bulletin.  The themes that emerged from the conference:

  • problems with the use of definitions for UPF,
  • the lack of causal evidence and defined mechanisms linking processing per se with poor health outcomes,
  • advice that may result in consumer confusion.
  • misalignment of UPF foods with dietary guidelines
  • unintended consequences for vulnerable groups

Comment: 

OK, the food industry is fighting back.  I think it’s a losing battle.  The UPF concept has so much evidence backing up its usefulness.  But I will say one thing about the point about unintended consequences.   It’s OK for rich people to avoid UPF but OK for poor people to eat them?  I think the food industry is in trouble on this one.  It has gotten away with pushing junk food for way too long.  The British Nutrition Foundation would be much more crredible if it put public health first.

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.

Industry funded study of the week: ultra-processed foods are OK, really

Jim Krieger of Healthy Food America sent me this Food Navigator article titled “Can ultra-processed packaged food play a role in healthy, sustainable diets of the future.”

Uh oh.  Another attack on the concept of ultra-processed foods.  These, you will recall, are strongly associated in observational studies with poor health outcome, and one clinical trial demonstrates them to cause people to eat more calories.

The makers of highly processed foods are understandably worried that the word will get out and people will stop eating them.

Clif Bar to the rescue.

It sponsored a small session to establish guidelines for making highly processed foods healthier: “Making Healthy, Sustainable Diets Accessible and Achievable: A New Framework for Assessing the Nutrition, Environmental, and Equity Impacts of Packaged Foods”

The publication emphasizes flaws in the concept of “ultra-processed,” an approach it says

lacks the nuance needed to holistically evaluate packaged foods within recommended dietary patterns. Additionally, there is considerable diversity of opinion within the literature on these topics, especially on how best to improve nutrition security in populations most at risk of diet-related chronic disease. In support of addressing these challenges, 8 sustainability and nutrition experts were convened by Clif Bar & Company for a facilitated discussion on the urgent need to drive adoption of healthy, sustainable diets; the crucial role that certain packaged foods can play in helping make such diets achievable and accessible; and the need for actionable guidance around how to recommend and choose packaged foods that consider human, societal, and planetary health.

Acknowledgments: “Staff at Clif Bar & Company developed the meeting agenda, synthesized all prework inputs, participated as observers in the workshop, and assisted in the gathering of the materials used to prepare this manuscript.”

Here is an ingredient list for an oatmeal raisin walnut Clif Bar:

ORGANIC ROLLED OATS, ORGANIC BROWN RICE SYRUP, SOY RICE CRISPS (SOY PROTEIN ISOLATE, RICE FLOUR, BARLEY MALT EXTRACT), ORGANIC ROASTED SOYBEANS, ORGANIC TAPIOCA SYRUP, ORGANIC CANE SYRUP, ORGANIC RAISINS, CHICORY FIBER, ORGANIC SOY FLOUR, WALNUTS, SUNFLOWER AND/OR SOYBEAN OIL, NATURAL FLAVORS, SALT, ORGANIC CINNAMON, MIXED TOCOPHEROLS (ANTIOXIDANT).

My definition of ultra-processed is that you can’t make it in your home kitchen because the ingredients are industrially produced and not available in supermarkets.  By this definition, the soy rice crisps are ultra-processed and maybe chicory fiber, but that’s about it.

The Clif people must be worried that they will be viewed in the same category as seriously ultra-processed snack foods.

Let’s give them and their parent company, Mondelez, credit for full disclosure.

Food marketing exposed !

TODAY: @Stphn_Lacey will moderate at 1:00 p.m. ET. Register HERE.

********

The Global Health Advocacy Incubator (GHAI) has just released this report.

The report documents how marketing of unhealthy food and beverages is linked to complex political, social, historical, cultural and economic forces that make it a key driver of unhealthy food environments:

  • Ultra-processed food and beverage product (UPP) marketers…saturate the marketplace with junk products through tactics that are aggressive, insidious and everywhere.
  • Consumers are ambushed with food marketing through the sponsorship of their favorite sports teams, the hidden product placements in their children’s educational shows and the free products that they receive at events.
  • The dangers are even more apparent when UPPs target children and adolescents who lack the developmental maturity to distinguish advertisements from entertaining or educational content.
  • The UPP industry is notorious for failing to take responsibility for its participation in creating an unhealthier planet.
  • The industry instead places blame solely on the individual or the guardian of the child.
  • UPP corporations exploit consumers through deception and undue influence, and also gain privileged spaces in policymaking tables.
  • UPP marketing threatens public health by decreasing state action to regulate food environments.

More evidence for the need to regulate ultra-processed foods and beverages (see my paper on this precise point).

Let’s get to it !

Canada’s new front-of-pack food label

Canada has joined the ranks of countries with front-of-package food labels alerting customers to products high in salt, sugar, and saturated fat.

I learned about this in a press release from Kate Comeau, Communications Advisor, Mission, Canada | Heart & Stroke

The official announcement from Health Canada is here. 

It comes with an explanatory Infographic.

I think the warning labels used in some Latin American countries work better, but this is a big step forward and is likely to cover the great majority of ultra-processed foods—and those are the ones that are best avoided.

Congratulations to Canadians who pushed for this.  Progress!

Industry-influenced commentary of the week: soy foods should not be considered ultra-processed

The commentary: Perspective: Soy-Based Meat and Dairy Alternatives, Despite Classification as Ultra-Processed Foods, Deliver High-Quality Nutrition on Par With Unprocessed or Minimally Processed Animal-Based Counterparts.  By Mark Messina, John L Sievenpiper, Patricia Williamson, Jessica Kiel, John W Erdman, Jr.  Advances in Nutrition, nmac026, https://doi.org/10.1093/advances/nmac026

Purpose: “This perspective argues that none of the criticisms of UPFs [ultra-processed foods] apply to soy-based meat and dairy alternatives when compared with their animal-based counterparts, beef and cow milk, which are classified as unprocessed or minimally processed foods (group 1). Classifying soy-based meat and dairy alternatives as UPFs may hinder their public acceptance, which could detrimentally affect personal and planetary health. In conclusion, the NOVA classification system is simplistic and does not adequately evaluate the nutritional attributes of meat and dairy alternatives based on soy.

Conflicts of interest: the statement is so long that I will save it for the end.

Comment: This commentary is a critique of the NOVA classification system, which puts foods in four categories by level of processing:

  • Group 1: Unprocessed/minimally processed (fruit, vegetables, nuts, grains, meat, milk with no complicated additives)
  • Group 2: Processed culinary ingredients (oils, fats, butter, vinegars, sugar, and salt eaten with added to Group 1)
  • Group 3: Processed (mix of groups 1 and 2, chiefly for preservation)
  • Group 4: Ultra-processed (industrially produced, cannot be made in home kitchens, chemical additives)

By this time, literally hundreds of studies have linked frequent consumption of ultra-processed (“junk”) foods to weight gain and its associated chronic diseases—type 2 diabetes, heart disease, etc—as well as high risk for poor outcome from COVID-19.  One carefully controlled clinical trial has shown that ultra-processed diets induce people to unwittingly take in more calories (“you can’t eat just one.”).

Artificial meats and dairy products made with plant proteins clearly meet the definition of ultra-processed.   Are soy products in a different category from those made with pea protein, for example?  Should plant-based meats in general be exempt from being considered ultra-processed?

I don’t think we know yet whether these products are better for health and the environment.  The issues are complicated and we don’t yet have the research or experience.

These authors report conflicted ties—many such ties—to companies making soy products and other products that might be considered ultra-processed:

My latest article: Regulating the Food Industry

The American Journal of Public Health has just published a first look—ahead of its print in June—at my most recent article, Regulating the Food Industry: An Aspirational Agenda [if you are not a member of the American Public Health Association, this will be behind a paywall, alas].

It begins:

I end it with policy recommendations for:

  • Dietary guidelines
  • Mass media campaigns
  • Taxes
  • Warning labels
  • Marketing restrictions
  • Portion size restrictions
  • Farm subsidies

Hence, aspirational.

And, I say,

While we are thinking in aspirational terms, let us not forget root causes. We must also demand policies that link agriculture to public health, keep corporate money out of politics, reduce corporate concentration, and require Wall Street evaluate corporations on the basis of social as well as fiscal responsibility.  In comparison with those challenges, takin gon the food industry should be easy.

Let’s get to work.
