Weekend reading: National Food Museum’s update on Trump Administration Food Scorecard

Michael Jacobson, founder and former president of the Center for Science in the Public Interest, is now promoting development of a National Food Museum.  One of its projects is keeping score on administration food policies.

He lists them as positive or negative, like this.

The most recent entry is dated June 26, a negative: the huge cut in SNAP benefits.

Alas, the negatives far outweigh the positives.  Take a look.

Eating your veggies isn’t easy: they cost more and there aren’t enough of them

The Bureau of Labor Statistics published this graph of the change in price of fresh vegetables since January 2024.  Prices have gone up a lot this year.

This did not get sent out to subscribers last week, so I’m trying again.

This may be explained not just by inflation, but also by a decline in the availability of vegetables in the food supply (defined as produced in the U.S., less exports, plus imports) as shown in this chart from the USDA.

If we want people to eat more healthfully, we need policies to make vegetables more widely available at lower cost.  Farmers have to make a living.  That’s why we need to rethink which foods get subsidized, and our entire agricultural system for that matter.

How about redesigning the agricultural system to prioritize food for people, instead of feed for animals and fuel for automobiles.

To explain, I’m posting this USDA chart again.

Nutritionally hilarious: Louisiana’s definition of “soft drinks” for its SNAP waiver

I am indebted to Melissa Fuster at Tulane University (congratulations on achieving tenure!) and Megan Knapp of Xavier University of Louisiana for telling me about this one.

The USDA has just approved a waiver for the State of Louisiana to exclude soft drinks, energy drinks, and candy from allowable purchases with SNAP benefits.

Check the definition of  excluded soft drinks [my emphasis]:

“Soft drinks” are defined as any carbonated nonalcoholic beverage containing high fructose corn syrup or artificial sweeteners.

By this definition, soft drinks made with cane or beet sugar are fully allowed to be purchased using SNAP benefits.

What is the difference between high fructose corn syrup and cane or beet sugar?  Not much.  All are mixtures of glucose and fructose and have the same number of calories.

So why the distinction?

Guess which state is the #2 producer of cane sugar.

As I said, nutritionally hilarious (see my clip in John Oliver’s Last Week Tonight on this point).

Editorial: Ultra-processed diets promote excess calorie consumption

I was asked to write an editorial commenting on a study published a couple of weeks ago that looked at changes in weight among people participating in a comparison of ultra-processed vs. minimally processed diets.

The study: Ultraprocessed or minimally processed diets following healthy dietary guidelines on weight and cardiometabolic health: a randomized, crossover trialNat Med (2025). https://doi.org/10.1038/s41591-025-03842-0.

The study has a long list of authors: Samuel J. DickenFriedrich C. JassilAdrian BrownMonika KalisChloe StanleyChaniqua RansonTapiwa RuwonaSulmaaz QamarCaroline BuckRitwika MallikNausheen HamidJonathan M. BirdAlanna BrownBenjamin NortonClaudia A. M. Gandini Wheeler-KingshottMark HamerChris van TullekenKevin D. HallAbigail FisherJanine Makaronidis & Rachel L. Batterham .

It must have been a huge amount of work to conduct this trial.  I can’t even imagine.

The lead author, Sam Dicken, explained the trial and its results on X.

My editorial has just been published in Nature MedicineUltra-processed diets promote excess calorie consumption (I have no idea why the editorial was not published at the same time as the study, but it is now out).

I fthought several things about the study to be especially interesting.

  • Participants, all overweight or obese, lived at their homes while under study.
  • They were fed ultra-processed meals for 8 weeks followed by minimally processed meals for 8 weeks, or vice versa.
  • Both sets of meals were designed to meet British guidelines for healthy foods; the ultra-processed foods were all healthy.
  • They were give about 4,000 calories a day and could eat as much as they wanted from that.
  • Participants lost weight no matter which diet they were on.
  • They lost twice as much weight on the minimally processed diet.
  • They ate more calories on the ultra-processed diet in comparison to what they were eating on the minimally processed diet.

Here’s the summary from my editorial.

One of the co-authors on the study is Kevin Hall, who did a rigorously controlled clinical trial of ultra-processed v. minimally processed diets and reported participants to be unwittingly consuming 500 calories a day more on the ultra-processed.

His study has been criticized for being too short in duration: two weeks on each diet.

This study kept participants on one or the other diet for eight weeks, and got a smaller but similar result.

Dicken et al also addressed a frequent criticism of the concept of ultra-processed foods: that the category excludes healthy foods like whole wheat commercial bread, commercial yogurts, power bars, and the like.  That’s what these participants were fed when they were on the healthy ultra-processed diet.

Here’s how I concluded my editorial:

Overeating, overweight, and increased risks for chronic disease are rapidly increasing public health problems for global societies.  Dietary guidelines in the UK and the United States have had little effect on improving overall dietary intake. None of these guidelines considers the degree of processing; the findings from Dicken et al. suggest that they should.

Brazil’s dietary guidelines, issued in 2015, say “avoid ultra-processed foods.” Researchers in the United States have called for guidelines and regulatory approaches to reduce intake of ultra-processed foods.

Despite ongoing debates about their definition, classification, and effects on health, in the context of maintaining or losing weight the evidence points to a clear message: minimize intake of ultra-processed foods.

If nothing else, the study provided further evidence for this sensible dietary advice.

Industry-funded study of the week: OLIPOP (prebiotic soda)

Here is yet another industry-funded study with a predictably favorable outcome, this one about a drink containing 6 grams of dietary fiber shown in this study to reduce blood glucose levels after consumption.

The study: Prebiotic soda lowers postprandial glucose compared to traditional soda pop: a randomized controlled trial.

Conclusion: a prebiotic soda is a favorable alternative to traditional soda formulations for managing postprandial blood glucose levels and maximal glucose excursion in generally healthy adults with overweight or obesity.

Competing interest statement: This study was funded by the manufacturer of the prebiotic soda beverage, OLIPOP, Inc. CFM, TB, EM, VK, and CC were employees of Biofortis, Inc., a Contract Research Organization that received funding from OLIPOP, Inc. to conduct the study. NV, MJM, and CM were employees of OLIPOP, Inc., the study sponsor company. AMV was a consultant of OLIPOP, Inc. for research support at the sponsor’s request.

Funding Statement: This study was funded by OLIPOP, Inc.

Comment: I particularly wanted to include this one because it is so blatantly done for commercial purposes, funded by the maker of the soda and conducted by employees or consultants. It belongs in the Journal of Industry-Funded Research, if such a thing existed.  Adding fiber to sodas to feed your microbiome?  I’d rather get mine from vegetables, grains, beans, nuts, and fruits.

Weekend reading: legal advocacy action guide

The Global Health Advocacy Incubator has issued an action guide to legal advocacy.

As GHAI puts it,

GHAI has launched a new Legal Advocacy Action Guide to show how legal professionals can advance public health objectives by identifying the most feasible legal strategies, drafting robust laws and regulation and using strategic litigation to promote and protect public health policy. Download it here, or read our sponsored Devex article summarizing how legal strategies can help advocates draft stronger laws and hold health-harming industries accountable. The new legal guide complements our Advocacy Action Guide.

This is a how-to manual for lawyers and advocates about how to use the legal system of a country to promote public health.  It’s divided into the 4 sections shown on the cover: Analyze, Draft, Assess, Litigate.

Each of these discussions comes with international case studies.

Here is an excerpt from the litigate section.

This guide is really useful.  Use it!

USDA is allowing states to ban sodas from SNAP: is this a good idea? Yes, if evaluated.

I thought I should say something about the new state bans on using SNAP benefit cards to buy sodas and other kinds of junk foods.

More states ban soda and ‘junk food’ purchases from SNAP benefits: Varying restrictions add more confusion for food companies already struggling with slowing sales.

This article, from Food Dive, says

  • Twelve states have now received approval to restrict benefits, with bans set to commence next year. The Department of Health and Human Services said the waivers aim to end the “subsidization of popular types of junk food.”

It points out that the bans vary in what they cover, and define candy and soft drinks in different ways.

Iowa, which has one of the most restrictive set of SNAP rules, is banning sugar-sweetened beverages that contain less than 50% juice, including sodas, energy drinks and flavored waters. The state is also restricting drink concentrates and powdered mix-ins.

The USDA has a web page devoted to SNAP Waivers (of existing rules governing what SNAP participants are allowed to buy).

Comment: I have long been in favor of pilot projects for banning sugar-sweetened beverages on SNAP (I was a member of the SNAP to Health Commission which issued a report in 2012.

Sodas are composed of sugars and water and have calories but no other redeeming nutritional value.

Even though we sympathized with the arguments that restrictions on purchases are condescending, we recommended pilot projects—along with research to evaluate them.  Would the bans change purchasing habits?  How would SNAP recipients feel about them?

It’s pretty clear how retailers feel about them.  Ouch.  Reduced sales.

The USDA turned down all requests for researchable pilot projects, ostensibly for logistical reasons.  Whatever.

Times have changed.

USDA’s SNAP waivers do not require research, unfortunately. I hope somebody in those states does some before-and-after data collection.

I worry that the waivers will be used as wedges to further cut SNAP benefits.

This one is a wait-and-see.  Stay tuned.

The MAHA Strategy report: two leaked versions

The big news in my world last week was the leaking of drafts of the forthcoming MAHA strategy report.

At least four reporters sent me copies for comments.

I did not do a careful comparison.  The main difference seems to be that the earlier version had this useful graphic about MAHA’s strategic intentions.

All of this may change when the final report is released, but here are my initial thoughts on its food sections.

First, the background: The first report, despite the hallucinated references, was a strong indictment of this country’s neglect of the health of our children. It stated the problems eloquently. It promised that the second report would state policies to address those problems.

As for this report: No such luck.

It states intentions, but when it comes to policy, it has one strong, overall message: more research needed.

Regulate?  Not a chance, except for the long overdue closure of the GRAS loophole (which lets corporations decide for themselves whether chemical additives are safe).

Everything else is waffle words: explore, coordinate, partner, prioritize, develop, or work toward.”

One good thing: the report mentions marketing to children, but only to “explore development of industry guidelines.”  Nothing about regulation.  This is too little too late.  We know what food marketing does to kids.  It’s way past time to stop it.

A few comments on specific issues mentioned.

  • “USDA will prioritize precision nutrition research…”  USDA?  NIH is already doing that, and it is the antithesis of public health research, the kind that really will make Americans healthier.
  • The report emphasizes color and other chemical additives (we knew it would), a definition (not regulation) of ultra-processed foods, and a potential front-of-pack label (unspecified).
  • It says it will modernize infant formula (really? how?), and will work to increase breastfeeding (again, how?).

And then there are the contradictions:

  • Improve hospital food, but the administration is taking money away from hospitals.
  • Teach doctors about nutrition (how?)
  • Prioritize “whole healthy foods” in nutrition assistance programs (but cut SNAP and WIC)
  • Expand EFNEP (but eliminate SNAP-ED)
  • Promote healthy meals in child care settings (also defunded)
  • Encourage grocery stores in low-income areas (how?)

How are they going to do this?  It doesn’t say.

Are there any teeth behind it?  It doesn’t look like this is anything more than voluntary (and we know how voluntary works with the food industry; it doesn’t).  None of this says how or has any teeth behind it.

And oh no!  MAHA boxes.  I’m guessing these are like what got given out—badly—during the pandemic.

It is striking that the leaked Make America Healthy Again (MAHA) Strategy Report, like its AI-assisted predecessor, embodies much of the idiosyncratic beliefs about food and drugs of one person: Robert F. Kennedy, Jr. He might be right about food dyes, but the report’s recommendations to alter our vaccine framework, restructure government agencies, and promote meat and whole milk are going to promote disease, not health…

The report…seems to twist itself into knots to make it clear that it will not be infringing upon food companies….But we also need to judge the administration by what it does, not what it says. And the administration’s attacks on SNAP, Medicaid, the health insurance exchanges, and the FDA and USDA workforces are poised to make America sicker, hungrier, and more at risk from unsafe food.
