California defines ultra-processed foods and bans them from school meals—by 2035 (!)

California’s governor, Gavin Newsom, has just signed the bill, “Pupil nutrition: restricted school foods and ultraprocessed foods of concern: prohibition.

This bill prohibits ultra-processed foods in federally funded school meals (K-12, breakfast and lunch), as well as competitive foods sold as snacks.

This means that

From the midnight before to 30 minutes after the end of the official schoolday, at each school, the only competitive foods that may be sold to a pupil are fruit, vegetable, dairy, protein, or whole grain rich food items; foods with a fruit, vegetable, dairy, protein, or whole grain item as its first ingredient; or combination foods containing at least one-quarter cup of fruit or vegetable.

These foods must also meet the following standards:

(1) Not more than 35 percent of its total calories shall be from fat. [This does not apply to individually sold portions of nuts, nut butters, seeds, seed butters, reduced-fat cheese or part-skim mozzarella cheese packaged for individual sale, eggs, fruits, vegetables that have not been deep fried, seafood, or a dried fruit and nut and seed combination.]
(2) Less than 10 percent of its total calories shall be from saturated fat. [This does not apply to reduced-fat cheese or part-skim mozzarella cheese packaged for individual sale, eggs, nuts, nut butters, seeds, seed butters, or a dried fruit and nut and seed combination.]
(3) Not more than 35 percent of its total weight shall be composed of sugar, including naturally occurring and added sugar. [This does not apply to fruits, vegetables that have not been deep fried, or a dried fruit and nut and seed combination.]
(4) Contains less than 0.5 grams of trans fat per serving.
(5) Contains not more than 200 milligrams of sodium per item, package, or container sold to a pupil.
(6) Contains not more than 200 calories per individual food item.
And then, beginning December 31, 2027, competitive foods may not contain color additives:
(A) Blue 1
(B) Blue 2
(C) Green 3
(D) Red 40
(E) Yellow 5
(F) Yellow 6
This is terrific, but don’t hold your breath.  The timeline:
  • June 1, 2028: The State Department of Public Health adopts regulations.
  • July 1, 2029: Schools begin to phase out restricted school foods
  • July 1, 2032: Vendors cannot offer restricted foods.
  • July 1, 2035: bill fully implemented.

Really?  Ten years to make this happen?  A lot can happen in that time….

Industry-funded studies of the week: Nuts!

My collection of studies funded by the nut industry is growing, so here are a bunch all at once.

Almonds: Almond Consumption Modestly Improves Pain Ratings, Muscle Force Production, and Biochemical Markers of Muscle Damage Following Downhill Running in Mildly Overweight, Middle-Aged Adults: A Randomized, Crossover Trial. Current Developments in Nutrition, Volume 8, Issue 9, 104432

  • Conclusion: This study demonstrates that 2.0 oz/d of almonds modestly reduces pain, better maintains muscle strength, and reduces the CK response to eccentric-based exercise.
  • Funding: This study was supported by the Almond Board of California

Peanuts: Peanut Polyphenols Are Bioaccessible and Inhibit Proliferation of Cultured Jurkat Leukemia Cells.  Current Developments in Nutrition, Volume 8, Supplement 2, July 2024, 102631

  • Conclusions: Polyphenol-rich PSE inhibits the growth and proliferation of Jurkat cells [a cell line derived from leukemia T-cells].
  • Funding: The Peanut Institute.

Pecans: Pecan Intake Improves Lipoprotein Particle Concentrations Compared with Usual Intake in Adults at Increased Risk of Cardiometabolic Diseases: A Randomized Controlled Trial.  The Journal of Nutrition, Volume 155, Issue 5, 1459 – 1465

  • Conclusion: Incorporating 57 g/d of pecans into the diet in place of usual snacks for 12 wk improved apoB, atherogenic lipoprotein subfractions, and the LP-IR in adults at risk of cardiometabolic diseases.
  • Funding: This study was funded by the American Pecan Council.

Pistachios: Nighttime Pistachio Consumption Alters Stool Microbiota Diversity and Taxa Abundance Compared with Education to Consume 1–2 Carbohydrate Exchanges (15–30 grams) over 12 Weeks in Adults with Prediabetes: A Secondary Analysis from a Randomized Crossover Trial.  Current Developments in Nutrition.  Volume 9, Issue 7107481July 2025 [Thanks to Martin Camhi for this one]

  • Conclusions: In adults with prediabetes, intake of 57 g/d of pistachios as a nighttime snack altered stool microbial community diversity and composition compared with a CHO-rich snack, providing evidence of stool microbial effects with pistachio consumption.
  • Funding: The American Pistachio Growers; Penn State’s Clinical & Translational Research Institute, Pennsylvania State University

Comment: If one nut producer does this, they all have to.  This is about market competition.  The idea is to convince you that nuts are superfoods performing health miracles and to eat more nuts.  These studies must be interpreted as marketing efforts.

Nuts are indeed healthy, but highly caloric—best eaten in small handfuls.  

If such studies should convince you of anything, it’s to eat the nuts you like.  They all can be shown to have health benefits.

Weekend reading: UNICEF’s Feeding Profit report

The UNICEF report: Feeding Profit: How food environments are failing children.

The UNICEF press release: Obesity exceeds underweight for the first time among school-age children and adolescents globally – UNICEF: One in 10 children worldwide living with obesity. Exposure to the marketing of ultra-processed foods found to be widespread.

the prevalence of underweight among children aged 5-19 has declined since 2000, from nearly 13 per cent to 9.2 per cent, while obesity rates have increased from 3 per cent to 9.4 per cent. Obesity now exceeds underweight in all regions of the world, except sub-Saharan Africa and South Asia….According to the latest available data, 1 in 5 children and adolescents aged 5-19 globally – or 391 million – are overweight, with a large proportion of them now classified as living with obesity.

One of the report’s major findings: “Globally, obesity has overtaken underweight as the more dominant form of malnutrition among school-age children and adolescents.”

Why?

  • Ultraprocessed foods aimed at children
  • Marketing of such foods to children
  • Unethical practices of companies making ultraprocessed foods
  • Inadquate legal measures and policies to stop such marketing

What to do?  Basically, oppose the practices, and institute measures and policies.

The report is beautifully documented and lays out the issues clearly and forcefully.  It’s well worth reading.  And taking action!

The National Food Museum’s collection of short food videos

The National Food Museum, is a project of Michael Jacobson, former founder and director of the Center for Science in the Public Interest (I’m on its Advisory Council).  It is currently still virtual, but provides all kinds of resources, short videos among them.

The Museum organizes them into several categories.  I took a look at the category of “kids (and others).”  Three examples, from among many:

This is a large collection of such things.  Enjoy!

A MAHA Win? Beginning to close the GRAS loophole.

The FDA is starting the regulatory process to close the GRAS Loophole.

This proposed rule, if finalized, would amend the Generally Recognized as Safe (GRAS) regulations in 21 CFR [Code of Federal Regulations] parts 170 and 570 to require the mandatory submission of GRAS notices for the use of human and animal food substances that are purported to be GRAS.

What?  You mean manufacturers are not already required to tell the FDA when they are putting new additives into foods?

No, they are not.  Hence, the “GRAS Loophole.”  Food manufacturers have been allowed to decide for themselves whether a new additive is safe and also to decide whether to inform the FDA about it.

Closing the loophole is a long-standing goal of food advocates.  Even I got into this one.

In 2013, I wrote a short editorial about the history and significance of GRAS determinations: Nestle M. Conflict of interest in the regulation of food safety: a threat to scientific integrity. JAMA Internal Medicine. 2013;173(22):2036-8. 

Here’s the FDA’s version of this history.

And Food Dive explains: FDA takes first step toward closing GRAS ingredient ‘loophole’

Dive Brief:

  • The FDA proposed a rule that companies provide health data and other documentation when declaring a new food ingredient or additive is safe, a step toward eliminating a voluntary approval process decried by Health Secretary Robert F. Kennedy Jr.
  • The rule would require companies to submit mandatory notices when declaring an ingredient is Generally Recognized as Safe, or GRAS. Currently, notices are voluntary, though strongly encouraged by the FDA.
  • The proposal is included among a list of upcoming regulatory priorities by the Trump administration. In March, Kennedy directed the FDA to explore rulemaking to eliminate companies’ ability to self-affirm that an ingredient is safe.

If the FDA can pull this off, it will indeed be a MAHA Win.

I hope it can, given how many FDA employees are no longer with the agency (~3,500 according to reports).

The new EAT-Lancet report: “predominantly plant-based”

The EAT-Lancet Commission has released its updated report on “healthy, sustainable, and just food systems.”

Let me point out immediately that the report was written by a great many authors (I could not easily count them), is 76 pages long, and is pretty much impenetrable without a lot of hard work.

As it did in its first report in 2019, the Commission’s report defines a Planetary Health Diet (PHD), which

represents a dietary pattern that supports optimal health outcomes and can be applied globally for different populations and different contexts, while also supporting cultural and regional variation…The PHD is based entirely on the direct effects of different diets on human health, not on environmental criteria….[It] emphasises a balanced dietary pattern that is predominantly plant-based, with moderate inclusion of animal-sourced foods and minimal consumption of added sugars, saturated fats, and salt.

The report offers “eight solutions and 23 actions to enable food systems transformation, which can be organised into coherent bundles of interventions that simultaneously advance health, environmental, and justice goals.”

the exercise of corporate power in ways that undermine public interests. The high degree of corporate concentration across food systems remains an intractable governance issue, which is partly due to the vast influence of large transnational food and beverage companies with considerable power.

Industry-funded study of the week: Eggs

I learned about this one from Women’s Health: New Study Confirms What We’ve Known About Eggs’ Health Impacts All Along.   Translation: Saturated fat raises blood cholesterol levels more than does dietary cholesterol.  Guess who paid for it!

The study: Impact of dietary cholesterol from eggs and saturated fat on LDL cholesterol levels: a randomized cross-over study. The American Journal of Clinical Nutrition. Volume 122, Issue 1, July 2025, Pages 83-91  https://doi.org/10.1016/j.ajcnut.2025.05.001.

Background: “Cardiovascular disease (CVD) remains a leading cause of death. Although dietary cholesterol from eggs has been a focus of dietary guidelines, recent evidence suggests that saturated fat has a greater impact on LDL cholesterol.”

Objectives: “This study examined the independent effects of dietary cholesterol and saturated fat on LDL concentrations.”

Methods: Participants were assigned to 3 isocaloric diets for 5 wk each:

(1) high-cholesterol (600 mg/d), low-saturated fat (6%) including 2 eggs/d (EGG);

(2) low-cholesterol (300 mg/d), high-saturated fat (12%) without eggs (EGG-FREE); and

(3) high-cholesterol (600 mg/d), high-saturated fat (12%) control diet (CON) including 1 egg/wk.

Results: Compared with CON, EGG but not EGG-FREE reduced LDL cholesterol. Across all diets, saturated fat intake was positively correlated with LDL cholesterol, whereas dietary cholesterol was not.

Conclusions: “Saturated fat, not dietary cholesterol, elevates LDL cholesterol. Compared with consuming a high-saturated fat diet with only 1 egg/wk, consuming 2 eggs daily as part of a low-saturated fat diet lowers LDL concentrations, which may reduce CVD risk.”

Funding: “This work was funded by the Egg Nutrition Center, a division of the American Egg Board. This funding source had no role in the design of this study, and no role in the analysis or interpretation of the data or writing of the manuscript.”

Conflict of interest: Three of six authors report financial support from the Egg Nutrition Center.

Comment

We know that saturated fat raises blood cholesterol levels.  Even so, it is very much to the interest of the Egg Nutrition Center to convince the world that eggs, the single greatest source of dietary cholesterol, (a) do not raise blood cholesterol levels, but also (b) actually reduce LDL and, therefore, heart disease risk.

Once again, industry-funded studies tend to produce results favorable to the sponsor’s interest.

Weekend reading: WHO’s new report on non-communicable diseases

The World Health Organization’s declaration on prevention of non-communicable diseases (NCDs—heart disease, type 2 diabetes, etc) was in the news this week (its source is here).

First, because of what it says and does not say:

These things are miserable to read.  You have to start with the “recognizes.” Here are two:

Recognize also that the main modifiable risk factors of noncommunicable diseases are tobacco use, harmful use of alcohol, unhealthy diets, physical inactivity and air pollution and are largely preventable and require cross-sectoral actions;

Recognize also that obesity is driven by multiple factors, including the unaffordability and unavailability of healthy diets, lack of physical activity, sleep deprivation, and stress;

But after all that, the declaration merely suggests [my comments]:

(i) promoting increased availability and affordability of nutritious food and information on healthy eating including through promoting efficient, inclusive, resilient and sustainable agrifood systems [how?]

(ii) improving policies and taking measures to reduce industrially-produced trans-fatty acids to the lowest level possible and reduce excessive levels of saturated fats, free sugars and sodium [by what means?]

(iii) providing nutritional information to consumers, such as through front-of-pack labeling;

(iv) putting in place public food procurement and service policies for healthy diets;

(v) protecting children from the harmful impact of food marketing, including digital marketing [How?  By what means?]

(vi) protecting, promoting and supporting optimal breastfeeding practices, including by regulating the marketing of breastmilk substitutes [at last, regulation] and

(vii) promoting adequate physical activity, including sports and recreation, and reducing sedentary behavior, including through
increasing access to public spaces.

What’s missing here?  Policy!

Whatever.  All of this could be moot.

Second, because the U.S. will not sign on to the declaration

The reasons are quite different.

HHS Secretary Robert F. Kennedy Jr, oddly since he wants to Make America Healthy Again, objected to the declaration.  He says he cannot “support W.H.O. policies that…promoted abortion and “radical gender ideology.”  This too is odd because neither is mentioned in the declaration.

He is also quoted as saying,

More specifically, we cannot accept language that pushes destructive gender ideology…Neither can we accept claims of a constitutional or international right to abortion. The WHO cannot claim credibility or leadership until it undergoes radical reform. The United States objects to the political declaration of non communicable diseases.

Again, odd because MAHA has a political agenda to end NCDs.

But I am more concerned about the failure of WHO to propose stronger measures.  Earlier drafts, apparently, contained stronger language.

Third, because conflicts of interest could be involved

What’s going on here?  Could this have something to do with it? Alarm as WHO accepts increasing amount of dark money from donors.

The WHO Foundation, according to Who funds the WHO Foundation? A transparency analysis of donation disclosures over the first 3 years of its operation, takes large donations from corporate and philanthropic groups and individuals without revealing who they are.

Oh dear.
