On this site, I comment on current events, answer questions, and respond to comments. I list speaking invitations under Public Appearances and recent writings under Publications (see list at left). Information about my other books, Food Politics: How the Food Industry Influences Nutrition and Health (University of California Press, 2002, paperback 2003, revised edition, 2007) and Safe Food: Bacteria, Biotechnology, and Bioterrorism (University of California Press 2003, paperback 2004), older writings, and press responses to my work on my other website, www.foodpolitics.com. Feel free to comment here on anything that interests you from either site. Welcome!

Even I am astonished by this one. Greg Miller of the National Dairy Council sends me all the studies that favor eating dairy products.  This one is a classic (of sorts) from the Journal of the American Dietetic Association .  The study compares the nutrient value of conventional milk, rbGH-free milk, and organic milk and finds–surprise!–no significant difference. In case you need a reminder, rbGH is recombinant bovine growth hormone, the genetically engineered hormone that increases milk production in cows.  Monsanto makes it.  OK, class: it’s quiz time.  The study has ten authors.  Guess who seven of them work for (or used to work for)? Guess who paid for the study?  And what are the other three authors doing there?

The Government Accountability Office, long a proponent of overhauling the U.S. food safety system and putting it under the aegis of a single food safety agency, has produced more evidence for its view (I love this title): Food Safety: Selected Countries’ Systems Can Offer Insights into Ensuring Import Safety and Responding to Foodborne Illness. The countries they looked at have farm-to-table safety systems in place, place primary responsibility on food producers (what a concept!), deal with risk intelligently, and have mandatory recall authority. We could do this too, maybe?

Sherry Weiss Poall of the RF Binder agency, which does public relations for Cargill, was kind enough to send me the collection of research studies the company is using to demonstrate the safety of Truvia/Stevia. The studies just came out in a supplement to Food and Chemical Toxicology, July 2008. Journal supplements typically are paid for by the research sponsor, in this case, Cargill. The authors of the dozen or so papers are scientists at Cargill and Coca-Cola or “independent” scientists who were paid for their work by Cargill “for consulting services and manuscript preparation.” The papers cover the chemistry and metabolism of stevia, its effects on human blood pressure and diabetes (none reported), and its effects on rats (minimal problems and only at absurdly high doses). Their entirely predictable conclusion: Truvia/Stevia is safe.

Stevia is a plant extract.  It isn’t poison ivy, it’s been around for awhile, and it ought to be safe. But sponsored research always raises questions about the objectivity of the science, especially when the papers read like press releases, which these do. I can’t wait to see what the FDA makes of all this. In the meantime, it’s on the market as an unapproved product.

I missed the Rockefeller Center launch of Cargill’s new sweetener, Truvia, but the press people followed up by sending me a sensational press kit in a gorgeous garden tote, complete with gloves. What can I say. It’s another artificial sweetener (OK, it’s an extract of plant leaves, which they claim makes it “natural”), this time in a little green packet. The press kit included a chocolate bar “made with Truvia natural sweetener.” It tasted like a dark bitter chocolate of the waxy type. Andy Bellatti of Small Bites, who works in my department, pulled out a Lindt dark chocolate bar for comparison. Truvia 191 calories vs. Lindt 210. No contest, I’d say. One thing intrigues. The packets and chocolate have Nutrition Facts labels, but the FDA has never approved Stevia so it’s been marketed as a dietary supplement with Supplement Facts labels. Reports are that the FDA is considering its approval as Generally Recognized as Safe (GRAS).  But to date the FDA has not approved it.  How is Cargill getting away with this? It plans to team up with Coca-Cola to seek international approval for it on the basis of research which they claim demonstrates its safety. But neither the website nor the press kit give the protocols for the studies or the actual data so it’s hard to judge. Cargill says it worked with FDA on this. FDA is letting Cargill use a Nutrition Facts label? On an unapproved product? Well, Cargill is a giant company and I guess it knows how to get what it wants. Oh. And how does Truvia taste? Sweet, with a bitter aftertaste. Is everyone waiting for this? Or is it just me who prefers sugar?

I start a new column today - Food Matters - in the San Francisco Chronicle’s Food section. It’s a Q and A, with room for comments on the online version. I will answer a question or two whenever it runs (how often? I’m not sure). This first one deals with the editors’ question: “What’s the most pressing nutrition issue today, and why?” In a word: calories.

And while we talking about calories, today’s New York Times printed my letter about  last week’s post on the 500-calorie cookie recipe.

Thanks (I think) to Hugh Joseph for forwarding the YouTube video, “The guy from CSPI.”  When I see things like this, I assume they are bought and paid for by the Center for Consumer Freedom, but it doesn’t say who made it or who paid for it.  I’m curious: how much does it cost to produce something like this, and who paid for it?  Anybody know?

A new study in Pediatrics finds most U.S. schools to sell junk food from food carts or vending machines. The situation isn’t too terrible in grammar schools but 97% of high schools sell junk food. I’m curious about that other 3%.

The Rudd Center at Yale has produced a handy summary of the research in support of calorie labels on menu boards.

The government of Great Britain has produced a major report on the need for healthier food systems, meaning the effects of current trends in food production and consumption on health, society, food safety, and the environment.  It will be interesting to see if they do anything with it.  I wish we could do things like this.  Maybe soon?

CBS News reports that FDA bureaucrats collected $35 million in bonus pay last year, a year in which the agency was charged with gross incompetence. Who got the biggest one? The person in charge of giving them out. Sigh.
