Dannon sued over Activia claims

Activia “probiotic” (promoting the growth of friendly bacteria) yogurt is a case study of successful marketing, based on its claims about the benefits of its particular live-and-active bacteria. Now its maker is being sued for overhyping the science and duping consumers into paying 30% more for Activia than for other yogurts. For what the company claims, see the Danone website.

Dannon, of course, rejects the charges.

To complicate the picture, Dutch investigators report the disappointing results of a clinical trial of probiotics in treatment of pancreatic cancer; the death rate was higher among study participants taking probiotics.   Somehow, I doubt this had anything to do with the probiotics but it does suggest a need for caution in interpreting studies of benefit as well as risk.

USDA’s new WIC standards: a great improvement!

Daniel from Ithaca writes about the USDA’s new nutritional standards for the WIC food packages for low-income pregnant women and children. He says, “it’s like I am on another planet,” meaning that he can’t believe that such good things are coming out of USDA, among them “More produce! Less juice! Less dairy! No full-fat milk! Dairy substitutes allowed! Fewer eggs! Whole grains! A greater emphasis on breastfeeding! He asks: Do you think that these changes, along with USDA’s hiring of Brian Wansink, will make for more straightforward Dietary Guidelines in 2010?

Thanks to Daniel for passing along this information. The WIC guidelines come out of a different part of USDA than the one that Brian Wansink heads but let’s hope that these changes–and his appointment–signal a new era in that agency, one that puts consumer interests first. One of Wansink’s jobs will be to oversee the appointment of USDA’s nominees to the 2010 Dietary Guidelines committee (the others come from the Department of Health and Human Services). Keep fingers crossed.

Canada’s Health Check program, checkmated

Dr. Yoni Freedhoff, who directs a bariatric medical clinic in Ottawa, sends a video report (in which he stars!) of an investigation into the Canadian Heart and Stroke Foundation’s Health Check program on food labels. This program is much like our American Heart Association’s (AHA) Heart Check program. For both programs, companies pay the organizations for use of the Check on the package label. Both use saturated fat and sodium as cut points for use of the logo, but don’t care much about sugars. I’ve argued for years that putting the AHA’s Check on sugary cereals misleads consumers and is not a good idea. The video–and the press accounts–of this investigation ought to hugely embarrass the organizations, maybe even enough to get them to end the programs.

Methylmercury in big, expensive tuna

So yesterday’s New York Times report on methylmercury in sushi tuna–a shocker because the most expensive tuna has the most of this toxin (of course it does; it’s bigger and accumulates more)–is now experiencing the expected backlash. Sushi eaters don’t seem to care much, and the tuna industry is fighting back through its public relations agency, the Center for Consumer Freedom (CCF). What is a tuna lover to do? If you aren’t pregnant, about to become pregnant, or a very young child (if you are, you should avoid big predatory fish like king mackeral, swordfish, tilefish, shark, and albacore tuna) the FDA and EPA say up to 6 ounces a week is OK. That leaves plenty of room for spending a fortune on sushi.

Here’s what Newsweek has to say about the CCF complaints. It’s great to see a news magazine blow the whistle on that group. Every word CCF says is paid for, and some tuna association pays it to say that methylmercury is not a problem.

Do dietary guidelines do more harm than good?

I wouldn’t even ask such a silly question if the American Journal of Preventive Medicine wasn’t going to publish a paper arguing just this point. Along with one of the editors of that journal, I wrote an editorial commenting on the paper, to which its authors added a rebuttal to our editorial. The authors argue that the government has no business issuing advice based on weak evidence. I would agree except that evidence will never be as good as we wish it would be because research on human nutrition is really, really hard to do. And when it comes to diet, dietary guidelines are not exactly radical; the basic advice hasn’t changed in 50 years. I summarize it like this: “eat less, move more, eat plenty of fruits and vegetables, and don’t eat too much junk food.” Michael Pollan gets it down to 7 words: “Eat food. Not too much. Mostly plants.” The Dietary Guidelines published in 2005 may take 70 pages, but in general, they say pretty much the same thing.

Welcome to Snickers Charged: Functional Candy Bar

Mars, which owns Snickers, brings us Snickers Charged, a line extension with more caffeine than a soft drink, taurine (an essential amino acid for cats), and a bunch of B-vitamins. Why do we need this? According to the public relations folks, “This new product responds to current marketplace trends and satisfies two need states craved by consumers who seek hunger satisfaction and a boost of energy.” Food, anyone?

New York City tries calorie labeling again

As of March 31, the NYC Health Department will require chain restaurants with more than 15 outlets to prominently display calorie information. I can’t wait to see how this will look and whether it will have any effect. Stay tuned!  And check “calorie labels” to see previous posts on the history of this decision.

Oh great. Vegetarian glucosamine made in China

I guess the world needs this. I know that lots of people think glucosamine helps relieve their arthritis pains, especially in the knees, but the science on it is really iffy. Any number of reviews conclude that glucosamine is ineffective but safe as a placebo. Well, at least you can get it now from vegetarian sources, made in China. Reassured? The manufacturer says “Most of the world’s glucosamine is manufactured in China anyway. What we’re doing is supplying a safer and purer glucosamine coming from the same geographical location.”
