It’s not a good time for the makers of herbal and vitamin supplements.  The better the research, the fewer benefits it shows.

Herbal supplements

DNA testing is demonstrating what many of us have long suspected: herbal supplements are not necessarily what they say they are.

As the New York Times reports, a recent study shows that many products purporting to be herbal supplements, actually contain rice, corn, or wheat (gluten-sensitive folks beware):

I would feel sorry for supplement manufacturers, if they hadn’t brought this on themselves.

First, they lobbied to get Congress to pass the Dietary Supplement Health and Education Act of 1994 (DSHEA).  This lets them advertise the benefits of supplements without much in the way of scientific substantiation.  It also excused the FDA from doing much regulation.

But DSHEA also required research.  Oops.   Although the point of asking for research was to demonstrate the benefits of supplements, things haven’t worked out that way.  Most of the research shows no benefit and, sometimes, harm.

And investigations like this one show what many have long suspected.  Without federal oversight, some supplement manufacturers will do whatever they can get away with.

Fortunately, rice substituted for St. John’s Wort is harmless and hardly matters, since St. John’s Wort doesn’t seem to do much anyway.

Vitamin Supplements

The latest review of the benefits—or lack thereof—of vitamin supplements for prevention of heart disease or cancer comes to cautious conclusions.

Limited evidence supports any benefit from vitamin and mineral supplementation for the prevention of cancer or CVD. Two trials found a small, borderline-significant benefit from multivitamin supplements on cancer in men only and no effect on CVD.

Borderline significance?  Not impressive.

The Natural Products Association, which represents supplement makers, issued a response:

• Multivitamin supplements should not be expected, without the combination of a healthy lifestyle, to prevent chronic disease.
• Dietary supplements are used by more than 150 million Americans on a daily basis. Research has shown that when taken in combination with other healthy lifestyle practices, such as consuming a wholesome diet and exercising regularly, people can benefit from dietary supplements.

Translation: if you consume a wholesome diet and exercise regularly, you really don’t need supplements.  And if you are not doing those things, supplements won’t do any good.

As for the 150 million Americans who take supplements: the ones I know tell me that they don’t care what the science says; they feel better when they take the pills.

Let’s hear it for placebo effects!

As always, I am indebted to Bill Marler for keeping me up to date on the latest outbreaks of foodborne illness.

The most recent—26 illnesses, 6 hospitalizations—seems caused by E. coli 0157:H7 contaminating grilled chicken salads sold by Trader Joe’s in California, Washington and Arizona.  According to the CDC:

Epidemiologic and traceback investigations conducted by local, state, and federal officials indicate that consumption of two ready-to-eat salads, Field Fresh Chopped Salad with Grilled Chicken and Mexicali Salad with Chili Lime Chicken, produced by Glass Onion Catering and sold at Trader Joe’s grocery store locations, are one likely source of this outbreak of STEC O157:H7 infections.

These are multiple ingredient products.  What could be the source of the toxic E. coli?

Marler provides some labels:

The contaminated ingredient could be Israeli couscous, something I can’t read (currents?), asiago cheese & toasted pecans with sweet basil dressing (first label), or white chicken meat, mixed greens, corn, peppers, sun-dried tomatoes, pepitas and asiago cheese with a jalapeno Caesar dressing (second label).

This will be hard to figure out.  There are lots of possibilities.  Likely candidates are mixed greens and jalapenos—this would not be the first time—but others could also have gotten contaminated along the way.

Marler also took the trouble to go to the website of Glass Onion Catering.  You will be happy to learn that this company’s “ salads, sandwiches, wraps and treats are crafted to the client’s specific recommendation. We only use the freshest, most natural ingredients to promote a healthy lifestyle,” and that the products are

• Trans fat free
• No artificial colors or flavorings
• No preservatives or additives
• No genetically modified ingredients
• Locally grown produce used (when possible)

Too bad they aren’t also free of this nasty form of E. coli.

Everyone who prepares or produces food needs to know how to follow standard food safety procedures.

You should not have to worry about buying foods at Trader Joe’s that make you sick.

To keep up with this is not so easy.  Because the products have meat (chicken) and vegetables (mixed greens, etc), they are regulated by two agencies: FDA and USDA.  This means three agencies are involved:

• CDC information 
• FDA information (and more FDA) 
• USDA information

Wouldn’t it make more sense to have one food safety agency?  Just asking.

It got my attention, for sure.

Recall that Got Milk! ads are funded by a USDA-sponsored research and promotion (a.k.a “checkoff”) program, this one, appropriately, for fluid milk.

Will this ad help reverse the long-term trend in declining milk sales let alone consumption?

Um.  Why don’t I think so.

I am indebted to Farm Futures for the heads up about the USDA’s just-published request for public input on what it calls “enhancing agricultural coexistence.”

Agricultural coexistence, the USDA says,

refers to the concurrent cultivation of crops produced through diverse agricultural systems, including traditionally produced, organic, identity preserved (IP), and genetically engineered crops.  As the complexity and diversity of U.S. agriculture increases, so does the importance of managing issues that affect agricultural coexistence, such as seed purity, gene flow, post-harvest mixing, identity testing, and market requirements.

My translation: The USDA wants producers of traditional crops and organic foods to stop complaining that GMOs are contaminating their crops, and producers of GMO crops to stop complaining that they get prosecuted if they try to save seeds from year to year.

The USDA explains that it is doing this in response to recommendations from its Advisory Committee on Biotechnology & 21st Century Agriculture.  This committee recommended actions to promote agricultural coexistence in five areas:

1. Potential compensation mechanisms
2. Stewardship
3. Education and outreach
4. Research
5. Seed quality

How come the USDA is collecting input on #3 rather than the far-more-likely-to-be-controversial #1 and #2?

Early in 2011, I wrote about USDA Secretary Tom Vilsack’s use of Cold War rhetoric to promote détente between growers of organic and GMO foods.  I pointed out that while the USDA had no intention of backing down on support of GM agriculture, it was at least recognizing the threat to organic production.

I noted that the USDA was unlikely to get very far with this initiative because so many farm groups representing industrial agriculture so strongly objected to Vilsack’s coexistence proposal.  The groups argued that coexistence could “adversely impact all producers of biotech crops, as well as the integrity of the American agriculture system.”

If you can’t do anything about underlying structural problems, try communication.

Have something to say about what it will take to support all systems of agricultural production?  Now is a good time to weigh in.

The Yale Rudd Center, in collaboration with the Robert Wood Johnson Foundation, has just released its 2013 report on fast food marketing to kids.

This report takes a look at what, if anything, the top 18 fast food restaurant chains have done to improve the nutritional quality of menu items since the last report in 2010.

Quick summary: not much.

It also analyzes changes in marketing to children and teens on TV, the internet, and social and mobile media.

Quick summary: getting worse and increasingly focused on minorities.

The FDA has just announced a proposal to withdraw GRAS (Generally Recognized As Safe) status for trans-fat.

My first reaction: Isn’t trans-fat already out of the food supply?  Hasn’t this been one of the food industry’s greatest public health achievements?

Once the FDA started to require trans-fat to be listed on food labels, food companies quickly stopped using partially hydrogenated oils (the source of trans-fat) and found healthier substitutes.  That’s why most food labels list zero grams trans-fat.

But the FDA allows food labels to say zero trans-fat if its amount is below 0.5 gram per serving.

Some manufacturers are still using a little.  This new initiative will encourage them to get rid of those last little bits.

Contrary to the New York Times headline, this is not exactly a ban on trans-fat.  If trans-fat is no longer GRAS, manufacturers can still file a food additive petition to continue using partially hydrogenated oils.

The Federal Register notice asks for input for the next 60 days.

I say congratulations to all:

• To food companies who worked hard to find ways to substitute healthier fats for trans-fats.
• To the FDA for finally taking care of the trans-fat 0.5-gram loophole.
• To Center for Science in the Public Interest for bringing health problems with trans-fat to public attention.
• To all of the researchers who did the science linking trans-fat to higher LDL-cholesterol levels and to heart disease risk.
• To the New York City health department for banning trans-fats from use in city restaurants.

Americans will be healthier as a result of all of your efforts.

At the moment, the FDA has not yet posted its Federal Register notice on the GRAS status of trans-fat. When it does, the notice should be available here.

Can money buy elections?  Apparently so.

Yesterday’s election results indicate that the GMO-labeling initiative in Washington state and the soda tax initiative in Telluride, CO both failed.

Washington’s I-522

According to USA Today, the defeat cost opponents $22 million.  All of that—except $550—came from out of state.

The top five contributors were the Grocery Manufacturers Association, Monsanto, DuPont Pioneer, Dow AgroSciences and Bayer CropScience.

But the Grocery Manufacturers Association was required to list its contributors.  The top five?  PepsiCo, Nestlé (no relation), Coca-Cola, General Mills, ConAgra  at about a million each when you add it all up.

USA Today reports:

Food industry ads claimed that the initiative would raise food prices. Labels would mislead consumers into thinking that products that contain genetically engineered ingredients are “somehow different, unsafe or unhealthy,” said Brian Kennedy of the Grocery Manufacturers Association, a food industry group based in Washington, D.C.

The Yes on 522 campaigns emphasized consumers right to know what’s in their food.

But PoliticoPro points out that because votes are mailed in, more than 600,000 votes may still be left to count.

The food and biotech industries used their considerable war chest to make ad buys across the state, pointing out all of the products that would not be covered under the measure — such as cheese, beer, restaurant food and even, they claimed, pet food — and pushing the message that the bill is misleading and would considerably raise food prices. They said the law would hurt Washington’s farm families.

As I told USA Today, sooner or later, one of these is going to pass. At some point the industry is going to get tired of pouring this kind of money into these campaigns and will beg for labeling, which is what should have happened in the first place.

The Telluride soda tax

Telluride is a small town, so the amounts are much smaller.

According to ProPolitico, the Colorado Beverage Association installed an onsite lobbyist to generate opposition to the measure through meetings and an Internet site.

The largest donors to the opposition campaign were a Texas billionaire who owns a second home in Telluride ($55,000), and the the local and national beverage associations. were the largest contributors to the anti-tax campaign, giving $20,000 and $55,000 respectively.

Taxes, of course, are never popular even when intended for public health purposes, as this one was.

Soda taxes too, will pass eventually.

Patience and fortitude.
