Egg prices! Yikes!

Thanks to Lisa Young for this:

 

The average price of a dozen eggs goes up and up.   It now averages $4.25 a dozen, and that’s for the cheapest kinds.

The New York Times explains

  • Inflation
  • The war in Ukraine
  • Higher feed costs
  • Higher energy costs (those hens have to be kept warm)
  • Avian flu (44 million hens died or were killed)
  • Higher-than-normal demand

It could get worse.  Avian flu infects animals as well as birds and could infect us.

How’s that for a cheery thought.

Small egg farms, anyone?

Or chickens as art, per National Geographic?

Do we need drugs and surgery to treat childhood obesity? Surely there are better ways.

So many readers have asked me to comment on the American Academy of Pediatrics’ Clinical Practice Guideline for the Evaluation and Treatment of Children and Adolescents With Obesity that I thought I ought to say something about it.

The guideline report is so long and detailed that I cannot imagine anyone actually reading it.  I started with the introduction, which summarizes basic facts.

  • 14.4 million children and adolescents are affected by obesity.
  • Obesity is a chronic disease with potentially serious health consequences
  • Childhood obesity is strongly affected by social determinants of health (poor education, poverty, racism, exposure to toxins, etc)
  • Childhood obesity is stigmatized in ways that fail to acknowledge social determinants.

What got press attention—and the attention of readers of this blog—is the AAP’s endorsement of drug and bariatric surgical treatment of obese children.

I cut right to the chase and looked at Appendix I, which gives the AAP’s algorithm for deciding on treatment options.  

The report’s major conclusions expand on this chart (the report does not define KAS, but I think it means Knowledge, Attitudes, and Skills):

KAS 9.  Pediatricians and other PHCPs should treat overweight (BMI ≥ 85th percentile to <95th percentile) and obesity (BMI ≥ 95th percentile) in children and adolescents, following the principles of the medical home and the chronic care model, using a family-centered and nonstigmatizing approach that acknowledges obesity’s biologic, social, and structural drivers.

KAS 10.  Pediatricians and other PHCPs should use motivational interviewing (MI) to engage patients and families in treating overweight (BMI ≥ 85th percentile to <95th percentile) and obesity (BMI ≥ 95th percentile).

KAS 11.  Pediatricians and other PHCPs should provide or refer children 6 y and older (Grade B) and may provide or refer children 2 through 5 y of age (Grade C) with overweight (BMI ≥ 85th percentile to <95th percentile) and obesity (BMI ≥ 95th percentile) to intensive health behavior and lifestyle treatment. Health behavior and lifestyle treatment is more effective with greater contact hours; the most effective treatment includes 26 or more hours of face-to-face, family-based, multicomponent treatment over a 3- to 12-mo period.

KAS 12.  Pediatricians and other PHCPs should offer adolescents 12 y and older with obesity (BMI ≥ 95th percentile) weight loss pharmacotherapy, according to medication indications, risks, and benefits, as an adjunct to health behavior and lifestyle treatment.

KAS 13.  Pediatricians and other PHCPs should offer referral for adolescents 13 y and older with severe obesity (BMI ≥ 120% of the 95th percentile for age and sex) for evaluation for metabolic and bariatric surgery to local or regional comprehensive multidisciplinary pediatric metabolic and bariatric surgery centers.

What is not in this guideline is anything that addresses the social determinants of childhood obesity.  What we have here is a focus on treating the symptoms, but getting nowhere near the cause.

It is difficult for someone like me who is not affected by those determinants to even imagine how drugs and surgery could be thought even remotely acceptable for children, even those over the age of 12, but I am not treating these kids.

Providers who do treat obese children tell me they are relieved to be able to offer options that might help kids achieve healthier weights.

As I see it, these should be absolute last resorts if used at all. And this is without even getting into issues of cost or our dysfunctional health care system.

In public health terms, drugs and surgery are “downstream” solutions to a problem that began way upstream with all those societal determinants.

If ever we needed upstream approaches, chldhood obesity is a prime example.

Upstream means policy changes that make healthy eating more appealing, accessible, and affordable  That’s what pediatricians need to be calling for.

This AAP report deliberately separates treatment from prevention.  It promises a discussion of prevention in a subsequent report.  I hope it is as hard hitting as any AAP report has ever been.

If childhood obesity teaches us anything, it is that our society needs to change in ways that are healthier for our children.

FDA organizational “reform:” clearly not fundamental, so just for show?

Last week, the FDA announced its proposed Redesign of Human Foods Program to Enhance Coordinated Prevention and Response Activities.   You can also watch this announcement on video.

This action comes in the wake of:

The FDA proposal comes with a vision of how the redesign would work.

The complaints and pressures argued for appointing a senior FDA official in charge of all FDA food programs and units.  Instead, the FDA proposes to create a Human Foods Program encompassing some, but not all, FDA food units.

Most prominently missing is the Center for Veterinary Medicine which deals with food for farm animals and pets.  These, however, fully participate in the food system for humans; they eat most of US corn production and loads of byproducts of human food production.  The systems for humans and animals are inextricably linked.

The organizational chart will look like this.  It splits the food units and connects them with dotted lines.  Good luck with that.  That was precisely the problem with the previous organization.

This looks better than the previous organization chart but falls far short of the authority needed to solve the nation’s food safety problem.

What’s needed?

  • Unification of food safety under a central authority that unites the functions of USDA and FDA (the Government Accountability Organization has been calling for that for decades).
  • Short of that, high-level FDA authority over the entire food supply under its jurisdiction.
  • And much more FDA attention to its public health as well as its safety functions.  It should be taking the lead on actions to prevent diet-influenced chronic diseases.

Hey, I can dream.

In the meantime, let’s see how the FDA’s new structure goes and who it hires into that key position in charge of human foods.

Industry-funded study of the week: Mulberry leaf

I saw this on NutraIngredients.com, one of those newsletters I read regularly: Study: Mulberry extract shrinks blood sugar spike by 40%.  

That headline was all I needed: Who paid for this?

Fortunately, the study was readily available: Mulberry leaf extract improves glycaemic response and insulaemic response to sucrose in healthy subjects: results of a randomized, double blind, placebo‑controlled study.  Pariyarath Sangeetha Thondre Helen LightowlerLis AhlstromAndrew Gallagher.  Nutr Metab (Lond). .2021 Apr 15;18(1):41.   doi: 10.1186/s12986-021-00571-2.

Conclusion: “Mulberry leaf extract can be used as part of lifestyle changes that may lead to healthy blood glucose levels.”

Acknowledgements:  The authors would like to thank Dr Chen Xie (CX) and Mrs Hongwen Yu (HY) for technical input during the conceptualization of the study and editorial commentary on the draft publication. CX and HY are both employees of Phynova Group Limited.

Funding: The work in this study was funded by Phynova Group Ltd, a privately held company that is the developer of Reducose® mulberry leaf extract. Phynova was involved in the study design and manuscript preparation but had no role in data collection and analysis.

Competing of interest: AG is an employee of Phynova Group Limited, the funder of the study. He was involved in the development of the product, design of the study and drafting of the manuscript, but was not involved in the collection, analysis or interpretation of data. PST, HL, and LA have declared they have no conflicts of interest.

Comment:  This degree of industry involvement turns this study into industry-funded marketing research, no matter how beautifully the science is conducted.  Please refer to my book, Unsavory Truthfor references to the studies backing up that statement.

Weekend reading: the FTC wants science to back up supplement health claims. What a concept!

The Federal Trade Commission has issued a Health Products Compliance Guide.

This amazing publication takes on the Dietary Supplement Health and Education Act of 1994.  That act effectively removed the FDA from regulating dietary supplements.  It also allowed supplement labels to make “structure/function” claims that the supplement supported some structure or function of the body, whether or not there was much in the way of scientific evidence to back up those claims (in contrast, FDA-authorized claims must be scientifically substantiated).

Now the FTC is saying:

Marketers of health-related products, including dietary supplements, should be familiar with the requirements under both FDA law and FTC law that labeling and advertising claims be truthful, not misleading, and substantiated.  The FTC approach generally requires that health-related claims be backed by competent and reliable scientific evidence substantiating that the representations are true.

Marketers cannot suggest unsubstantiated benefits, safety, or other characteristics.

Example 4:  An ad for an infant formula states that an ingredient added to the formula can reduce the symptoms of colic.  The ad includes an unrelated chart from a pediatric journal showing that, as a general principle, the length of time that colicky babies cry tends to decrease over the first 12 weeks of life…Using the graph in an ad for the infant formula likely implies that the formula, rather than the babies’ ages, causes the decrease in crying time.

Claims have to be qualified.

Example 10:  An energy drink contains an ingredient that, when consumed daily over an extended period, can result in a significant increase in blood pressure.  Even absent any representation about the product’s safety, the marketer should disclose this potentially serious risk.

Qualifying information must be clear and straightforward.

Example 13:  A company has results from two studies suggesting that its supplement helps to maintain healthy cholesterol levels.  There are, however, significant limitations to each of the studies… The company makes a claim in advertising that “promising, preliminary scientific studies show that our product may be effective in reducing cholesterol.”  The use of the words “promising,” “preliminary,” and “may” is unlikely to sufficiently convey the limitations of the science.

Assertions about the strength of evidence must be accurate.

Example 16: An ad for a supplement includes the statement “Scientists Now Agree!” in discussing the product’s benefit.  This statement likely conveys to consumers that the state of science supporting the benefit has reached the level of scientific consensus.  Unless the advertiser possesses evidence demonstrating that scientists have reached that consensus, the claim is false.

Marketers must consider the totality of the science.

Example 30:  An advertiser wants to claim that a supplement will substantially reduce body fat.  The advertiser has two controlled, double-blind studies showing a modest but statistically significant loss of fat at the end of a six-week period.  However, there is an equally well-controlled, double-blind 12-week study showing no statistically significant difference between treatment and control groups.  Assuming other aspects of methodology are similar, the studies taken together suggest that, if the product has any effect on body fat, it would be very small and may not persist over time.  Given the totality of the evidence, the claim is unsubstantiated.

Here’s the press release. 

The bottom line:  The FTC is requiring evidence for health claims on supplements.

This will affect claims for thousands of supplement products.

Enforcement anyone?  This should be fun to watch.

Update on plant-based foods: Yes, another one

I don’t care what the arguments are about plant-based meats (see Deena Shanker’s riveting piece in Bloomberg News), they and other plant-based alternatives to animal foods still look like a hot trend to me.   I base this on what pours into my inbox.

One view of the trends:

The new products:

Funding and expansions:

Marketing innovations:

Even so, the criticisms continue:

I am ever fascinated by all this. You too?  Stay tuned.

Annals of food politics: “Woke” M&Ms

I kept coming across this on Twitter, but had no idea what it was about.

I’ve always said food explains everything.  And here we are in the middle of M&M-inspired culture wars.

The New York Times to the rescue !

M&M’s, the ubiquitous candy brand owned by Mars Wrigley, announced on Monday that it would take “an indefinite pause” from its “spokescandies,” deciding that the cartoon characters with arms, legs and minimal facial features were simply too divisive for a polarized America to take…figures on the political right, including Tucker Carlson of Fox News, have criticized the candy as “Woke M&M’s,” owing to a series of cosmetic tweaks in recent years.

I love what the Times says next: “Here’s how we got here, to the extent that it’s possible to explain.”  Right.

The Times attributes this to Fox News’ sTucker Carlson:

In January 2022, M&M’s gave the aching feet of its two female spokescandies a break, replacing the green M&M’s heels with flats and swapping the brown M&M’s stilettos for smaller, more comfortable heels…“M&M’s will not be satisfied until every last cartoon character is deeply unappealing and totally androgynous,” Mr. Carlson railed on his show. “Until the moment when you wouldn’t want to have a drink with any one of them. That’s the goal. When you’re totally turned off, we’ve achieved equity. They’ve won.”

All of this is enough to make me want to run out and eat some M&Ms.

You can’t make this stuff up.

Impossible Foods picks a public fight with a reporter

When I saw this tweet from Tom Philpott, I knew immediately what it was about.

I had seen Deena Shanker’s investigative report in Bloomberg News, not least because I’m quoted in it: Fake Meat Was Supposed to Save the World. It Became Just  Another Fad.

The article’s subtitle: “Beyond Meat and Impossible Foods wanted to upend the world’s $1 trillion meat industry. But plant-based meat is turning out to be a flop.”

And then I saw this ad in the January 22 New York Times.

Anonymous Reddit writers saying things like “I suspect it’s coming form [sic] a news outlet paid money to write an article by people who make money from meat sales.”

A badge of honor for Deena Shanker indeed.  Clearly, she hit a nerve.

Meat alternatives still have their fans and I’m not ready to write off fake meat just yet.   But this ad makes me much less sympathetic to this particular Cause.

Ironic addition, January 30: Impossible Foods to lay off 20% of its staff.
