Who is getting billions in farm payments?

This Tweet got me started on farm payments.

Good point.  It sent me to John Newton who is an agricultural economist and lobbyist for the Farm Bureau.

The red sector is payments to agricultural producers and processors.  The tiny little sliver goes to food and nutrition.

All of this got me thinking.  What’s the Big Picture here?

Fortunately, Politico has done the work.

And here are a few other comments on how this is playing out—with taxpayer dollars, recall.

If ever we needed accountability—and rational agricultural policy—the time is now.

Dubious health claim of the week: cranberries and UTIs

The FDA has just announced a Qualified Health Claim for Certain Cranberry Products and Urinary Tract Infections.

The U.S. Food and Drug Administration announced today in a letter of enforcement discretion that it does not intend to object to the use of certain qualified health claims regarding consuming certain cranberry products and a reduced risk of recurrent urinary tract infection (UTI) in healthy women.

Huh?

The FDA does not exactly approve health claims that are not backed up by scientific evidence.  It just doesn’t object to them.

This one, no surprise, comes in response to a request by Ocean Spray Cranberries, Inc, which would love to be able to market its products as helping to prevent UTIs (which lots of people believe).

Here’s what the FDA says about the science.

After reviewing the petition and other evidence related to the proposed health claim, the FDA determined that the scientific evidence supporting the claim did not meet the “significant scientific agreement” standard required for an authorized health claim.

Hence, the Qualified health claim.

If Ocean Spray wants to use the claim, it has to put atatements like these on the label:

  • For cranberry juice beverages: “Consuming one serving (8 oz) each day of a cranberry juice beverage may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women. FDA has concluded that the scientific evidence supporting this claim is limited and inconsistent.”
  • For cranberry dietary supplements: “Consuming 500 mg each day of cranberry dietary supplement may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women. FDA has concluded that there is limited scientific evidence supporting this claim.”

Why does Ocean Spray want this?  Because believers will ignore the FDA disclaimers.  Ocean spray says:

To that end, Ocean Spray will use its medical attributes in the place they matter most–running a campaign on the WebMD site later this year. “We’re going to be all over WebMD,” he said, noting that the connection between cranberry juice and urinary tract health is the fifth most discussed topic on the influential health site.

Qualified health claims are about marketing, not science.

But I know how you feel.  UTIs are awful.  If all it takes is cranberry juice….

“Let’s Ask Marion” is coming September 1!

I just got the first copies of my forthcoming book with Kerry Trueman, Let’s Ask Marion: What You Need to Know about the Politics of Food, Nutrition, and Health.

The publication date was supposed to be September 29 but University of California Press moved it up to September 1.  The y will also publish the e-book on September 1.

This means it can be used in fall classes (I’m using it in the NYU undergraduate class I’m teaching on Food Politics in the Covid-19 Era.

Information about the book and its Table of Contents are here.

You can read the Introduction here.

And UC Press sent me these photos.

It’s a tiny book, not much bigger than a coffee mug.

Here’s the back cover:

And here’s the first page of the table of contents.

Income and sugary beverage consumption

A recent study confirms what we already knew: poorer people drink more sugary beverages than richer people.

This analysis suggests the richest 10% of families drink about 2.5 fewer sugary drinks a week than those in the poorest 10%.

These investigators found this relationship to hold up “even after taking into account things like education, race, gender, cognitive abilities and interest in nutrition.”

Drinking sugary beverages correlates with all those factors as well as with poor diets in general, overweight, the diseases for which overweight is a risk factor, and overall mortality.

I discuss the evidence for all that in my book, Soda Politics: Taking on Big Soda (and Winning).

Don’t raise industrial chickens near orchards, please

For two years, the investigators took swab samples of soil surface, air, and leaves in an almond orchard 35 meters downwind from an industrial poultry farm.  They compared the samples to those collected from two almond orchards (controls) nowhere near a poultry operation.

E. coli was isolated from 41 of 206 (20%) and 1 of 207 (0.48%) air samples in the almond-poultry and control orchards, respectively….On average, the amount of dry solids on leaves collected from trees closest to the poultry operation was more than 2-fold greater than from trees 120 m into the orchard or from any of the trees in the control orchards.

Members of the family Staphylococcaceae—often associated with poultry—were, on average, significantly (P < 0.001) more abundant in the phyllosphere of trees closest to the poultry operation (10% of relative abundance) than in trees 120 m into the orchard (1.7% relative abundance) or from any of the trees in control orchards (0.41% relative abundance).

Poultry-associated microorganisms from a commercial operation transferred a short distance into an adjacent downwind almond orchard.

Contamination of leafy greens grown in California and Arizona near large cattle operations has been a problem for a long time.

This new study adds two pieces of information:

  • Toxic bacteria can travel downwind in air.
  • Poultry operations are just as contaminating as cattle operations.

The moral of this story: Do not grow nuts or fruit or vegetables near industrial meat or poultry operations.

Update on Covid-19 among meatpacking workers: an American tragedy

Leah Douglas at the Food and Environment Reporting Network (FERN) is doing a great public service.  She has a website where she reports Covid-19 cases among workers in the food system.

These are not trivial.  As of July 24, she reports Covid-19 cases in:

  • 370 meatpacking plants
  • 139 food processing plants
  • 74 farms and production facilities

As for confirmed cases:

  • 37,197 meatpacking workers
  • 4,635 food processing workers
  • 4,927 farmworkers

She reports 188 deaths among these workers

  • 168 among meatpacking workers
  • 14 among food processing workers
  • 6 among farmworkers

Here’s what this looks like:

Where is all this happening?  She’s got a chart for that too.

These places have a lot to answer for.

This is an American tragedy.

Amazing food study of the week: saurkraut prevents Covid-19 !

What is one to make of a headline like this?

CABBAGE DIET HOPE: Eating sauerkraut, coleslaw and raw cabbage ‘could protect against coronavirus.'”

I raced right to the study, fast-tracked in a not-yet-peer-reviewed paper:

Title: Association between consumption of fermented vegetables and COVID-19 mortality at a country level in Europe, by Susana Fonseca, et al.  

The study: The investigators compared consumption of fermented vegetables (and also pickled/marinated vegetables, fermented milk, yoghurt and fermented sour milk) in the European Food Safety Authority (EFSA) Comprehensive European Food Consumption Database to COVID-19 mortality.

Result: For each g/day increase in the average national consumption of fermented vegetables (but not the others), the mortality risk for COVID-19 decreased by 35.4%.

Comment: One food—saurkraut—reduces the Covid-19 mortality rate by 35%?  This would be an astounding result for any single food.  The authors’ hypothesis is that consumption of fermented foods promotes a microbiome that helps resist infection, even, apparently, respiratory infections.

At the moment, I’m judging this study as a delicious example of why correlation does not equal causation.

Eating saurkraut is just fine if you like it.

But for preventing Covid-19?  I’m sticking to masks and social distancing while waiting for further research.

Weekend reading: health claims in food advertising.

Chefs Best has issued a short, handy guide to making health claims in advertising that will stand up to the Federal Trade Commission’s scrutiny.

The guide divides advertising claims into three categories.

How can you tell if your claim is OK?

First, consult with competent legal counsel. The FTC advertising substantiation policy states, “Objective claims
for products represent, explicitly or by implication, that the advertiser has a reasonable basis supporting these
claims”. It goes on to state, a “reasonable basis” means “objective evidence that supports the claim” and “at a
minimum, an advertiser must have the level of evidence that it says it has.” “If the ad is not specific, the FTC looks
at several factors to determine what level of proof is necessary, including what experts in the field think is needed
to support the claim.”

Good luck with that.  The FTC generally goes along with what the FDA says about health claims.

As for those of us who are the target of health claims: it’s best to remember that health claims are about marketing, not health.
