Q. Have you seen this clever project? By the filmmakers of King Corn, comes “Truck Farm,” a movie about the smallest CSA in the biggest city. You can grow food anywhere….
A. Have I seen it? Of course I’ve seen it.
I’m in it.
I joined the CSA and got filmed when they delivered my share.
Cool.
Q. I’ve just been thinking about this in light of the current situation – the worst drought in 60 years. Do you think that there is more awareness of global food security, the global food system and ‘our responsibility’?…I find this a complex issue and I think it is incredibly important we don’t forget it as other news items are prioritized.
A. Your question arrived just as the New York Times put another one of those devastating photographs of a starving child on its front page, this time to illustrate the famine in Somalia.
Like all famines, this one is politically induced. What’s going on in Somalia these days is a consequences of a lengthy colonial history. A colleague and I wrote a controversial paper about such issues more than 15 years ago (see Nestle M, Dalton S. Food aid and international hungerr crises: the United States in Somalia. Agriculture and Human Values 1994;11(4):19-27)
At the time, I was struck by how often the history of humanitarian aid repeats itself. We keep making the same mistakes.
This is because it seems—and in the case of Somalia is—much easier to deal with the immediate demand for food aid than to address the underlying politics that caused the problem in the first place.
But if we don’t deal with the underlying politics, the same tragedies occur again and again.
More awareness? I don’t see it happening—just increasing feelings of helplessness in the face of so much human misery.
What to do? I have no answers. Somalia is too dangerous for amateurs.
Readers: Thoughts? Suggestions for action?
I’ve been rounding up information about the Cargill recall of ground turkey contaminated with Salmonella Heidelberg. William Neuman at the New York Times related the story on August 3. Same old same old.
Cargill is a huge company with, as Bill Marler counts them, a long history of food safety problems. Did Cargill not bother to test for pathogens? As I explain in my book Safe Food: The Politics of Food Safety, no meat company wants to test for pathogens. If they found pathogens, they would have to recall the products.
And where was the USDA in all of this? Best not to ask.
The USDA was testing. The testing found Salmonella. The USDA did nothing.
According to the Wall Street Journal,
Federal officials said they turned up a dangerous form of salmonella at a Cargill Inc. turkey plant last year, and then four times this year at stores selling the Cargill turkey, but didn’t move for a recall until an outbreak killed one person and sickened 77 others.
How come?
Food-safety specialists said the delay reflected a gap in federal rules that don’t treat salmonella as a poisonous contaminant, even if inspectors find antibiotic-resistant forms such as the Heidelberg strain implicated in the latest outbreak.
But CDC investigations show that turkey-related illnesses have been reported for months. Despite the reports, the USDA took its own sweet time insisting on a recall.
The rationale for the delay is—get this—the USDA believes it does not have the authority to order recalls for any contaminant except E. coli O157:H7. It has no authority to recall meat contaminated with Salmonella or other toxic forms of E. coli.
Or at least that’s how USDA interprets the legal situation (for the history of all this, see Bill Marler’s summary.
One reason for the USDA’s foot-dragging must surely be pressure from the meat industry which wants as little testing as possible and preferably none. The meat industry would rather leave it up to you to cook your food safely.
According to a report by Elizabeth Weise in USA Today,
The reasons these bugs aren’t currently regulated are a mix of politics, money and plain biology — the bacteria are constantly evolving and turning up in new and nastier forms, making writing rules about them a bit of a nightmare. For example, the German E. coli variant that sickened more than 4,075 in Europe and killed 50…wasn’t known before this spring.
The meat industry takes advantage of this situation and argues:
“We don’t have a true baseline determining the prevalence of these organisms in the beef supply,” says Betsy Booren of the American Meat Institute (AMI) Foundation, the research arm of AMI. Without knowing how common they are, it’s impossible to say whether they should be considered adulterants, she says.
What they seem to be saying is that meat always has bacteria on it. And just because these particular bacteria can kill people doesn’t mean the industry is responsible if anyone gets sick. But shouldn’t the industry be doing a better job?
In Food Safety News, Michele Simon has a terrific analysis of the safety loopholes that allow this absurd situation to continue:
How did the meat industry get so powerful that it can keep USDA from doing its job? Now, instead of preventing illnesses from occurring by requiring testing with teeth, we have USDA regulations that are so lax they allow almost half the samples tested at ground turkey plants to be contaminated with Salmonella — a pretty easy standard to meet. And one that allowed this outbreak to occur.
I keep asking: how much worse does it have to get before Congress does something about ensuring safe food. Cargill’s inability to protect the public from unsafe meat is reason alone to create a single food safety system that unites the functions of USDA and FDA.
If Congress isn’t ready to take that step, it could at least give USDA the power to act and the FDA the funding it needs to do its job.
Q. I would love to hear what you think about hydroponic food. My instincts tell me that organic soil is full of life and traces of nutrients and elements we don’t fully understand and here we have another frankenfood that is scientifically derived.
A. Frankenfood is too strong but I’m basically with you on this one. I don’t get hydroponics. Obviously scientists have figured out enough about plant nutrient requirements to keep them alive in water and nutrient broth but what’s the point? Soil works really well and is bound to contain substances we don’t even know about. These may even influence taste.
Chefs say even the best of hydroponic vegetables, according to a recent New York Times article, are not considered serious replacements for field-grown lettuces because they can’t reproduce the flavor.
My suspicion? People who like hydroponics don’t like getting their hands dirty (but isn’t that half the fun?).
I’ve just turned in the copy-edited manuscript of Why Calories Count: From Science to Politics (pub date March 2012) and now have time to catch up on some questions:
Q. I was recently given to read a book titled “The China Study” which is based on research conducted in 1970’s in China by Dr. Colin Campbell. His main conclusion is that eating dairy and meat causes cancer. His resolution is that a plant-based diet (i.e. vegan) is the (only?) healthy diet for humans. This book has made strong enough of a point to convince several of my friends to “convert” to a vegan diet in order to save their health. Could you share some comments on the validity of the research and conclusions this book presents with regards to detrimental effects of dairy and meat on human health?
A. Campbell makes a forceful argument based on his interpretation of the research and on case studies of people whose diseases resolved when they became vegans. And yes I’ve seen Dr. Campbell’s new movie, Forks over Knives. The first half is a terrific introduction to how the current food environment promotes unhealthy eating. The second half promotes Dr. Campbell’s ideas about the hazards of meat and dairy foods.
Whether you agree with these ideas or not, the film is well done and worth a look.
Some scientists, however, interpret the research as demonstrating that people are healthier when they eat dairy foods. For example, the enormous consensus report on diet and cancer risk from the American Institute for Cancer Research and the World Cancer Research Fund concluded in 2007 that eating lots of red meat and processed meat is convincingly associated with an increased risk of colorectal cancer (but no others).
On the other hand, they found dairy foods to be associated with a decrease in the risk of colorectal cancer. They found limited and less convincing evidence that dairy foods might decrease the risk of bladder cancer but increase the risk of prostate cancer.
How to make sense of this? These are two food groups in the diets of people who consume many kinds of foods and who do many things that might increase or decrease cancer risk. Given this complexity, one food or food group seems unlikely to have that much influence on cancer when considered in the context of everything else people eat and do.
Nutrition research, as I am fond of saying, is difficult to do and requires interpretation. Intelligent people can interpret the studies differently depending on their point of view.
The new Dietary Guidelines say to cut down on saturated fats. Those are most plentiful in meat and dairy foods (plant foods have them, but in smaller amounts). Pretty much everyone agrees that plant-based diets promote health/ But whether they have to be 100% plant-based is highly debatable.
The new USDA MyPlate food guide suggests piling plant foods—fruit, vegetables, and grains—on 75% of your plate so the argument is really about what goes on the remaining 25%, what USDA calls the “Protein” section. You can put beans in that quarter if you don’t want to eat red meat, poultry, or fish.
Q. I’d love to hear your take on the recent walnut flap [accusations that the FDA now considers walnuts to be drugs]. I suspect walnuts got caught with such offenders as Pom, Froot Loops, and Juicy-Juice, but I’d love to find out what the FDA actually said about this. For some odd reason I don’t believe the article is presenting the whole truth.
A. This is a health claims issue. The FDA is not saying walnuts are drugs. It is saying that Diamond Walnut is claiming walnuts as drugs on package labels. How so?
The labels say the omega-3 fatty acids in walnuts may help lower cholesterol; protect against heart disease, stroke and some cancers (e.g. breast cancer); inhibit tumor growth; ease arthritis and other inflammatory diseases; and even fight depression and other mental illnesses. These are disease claims for which the FDA requires scientific substantiation.
The company’s petition did not provide that substantiation so the FDA issued a warning letter. In general, you should be skeptical any time you see a nutritional factor advertised for its ability to prevent or treat such a broad range of problems.
Q. A question about sugar and how it is counted: My books say: 4 g = 1 teaspoon = 15 calories. My Illy Caffe says 10 g of sugar, but 50 calories. Ingredients: coffee, sugar, potassium bicarbonate, potassium citrate. If the drink is 50 calories, shouldn’t it say 12 g or more for the sugar listing?
A. Sugar should be the only ingredient that has calories in this coffee but I’ve seen calorie lists that say 5 calories per gram for sugars. Food companies have some leeway in the way they compute calories. Illy may be using a method that gives 5 rather than 4. But the difference between 40 and 50 is hardly measurable and I wouldn’t worry about amounts this small, annoying as imprecise figures may seem.
My monthly (first Sunday) Food Matters column is in answer to a question about the deeper meaning of the fuss over McDonald’s “healthier” Happy Meals.
Q: Wouldn’t it be the best form of activism to encourage people to buy McDonald’s slightly-less-bad-for-you Happy Meals? If the new formulation flops, do you really think McDonald’s will take more baby steps in the same direction? Aren’t you letting perfect be the enemy of the good?
A: The question, for those of you ignoring national media, refers to McDonald’s announcement that it plans to restructure its Happy Meals for kids by adding fruit, downsizing the fries and reducing calories by 20 percent and sodium by 15 percent.
Skeptic that I am, I took a look at McDonald’s lengthy press release. The company does not claim to be making healthier changes. It says it is offering customers improved nutrition choices. This is something quite different.
At issue is the default meal – the one that gets handed to you without your having to ask for anything. Plenty of research shows that although customers can request other options, most take the default. So the default is what counts.
McDonald’s says its new default will include a quarter cup of apple slices (how many slices can that be?), less sodium and 1 ounce less of french fries (thereby reducing calories and fat). These are steps in the right direction, but tiny baby steps.
The rest is up to you: hamburger, cheeseburger or McNuggets.
As for beverage, the press release says, “McDonald’s will automatically include produce or a low-fat dairy option in every Happy Meal.”
This sounds great. “Automatically” makes me think the default Happy Meal will come with low-fat milk. No such luck. It’s up to you to choose from soda or low-fat chocolate or plain milk.
Want something healthy? You have to ask for it. And the meal still comes with a toy, although the meal isn’t healthy enough to qualify for a toy under the San Francisco’s nutrition standards, which are scheduled to go into effect in December.
The McNuggets meal meets the San Francisco standard for sodium, overall calories and for saturated fat – if you choose low-fat white milk. It fails the other criteria. Fat provides about 40 percent of the calories (the standard is 35 percent), and fruit misses the mark by 50 percent. The hamburger and cheeseburger meals fare worse. And even if french fries count as a vegetable, they don’t reach the three-quarter-cup standard. Sodas, of course, have too much sugar.
No toy for you, San Francisco kids.
So let’s get back to the underlying question: Isn’t perfect the enemy of the good? Aren’t baby steps like these in the right direction and, therefore, deserving of support?
I don’t think so. McDonald’s proposed changes are a reason to ask a different question: Is a better-for-you Happy Meal a good choice? Wouldn’t your child be better off eating something healthy, not just slightly healthier?
Couldn’t McDonald’s, the largest fast-food maker in the world, come up with something genuinely healthy that also tastes good?
“Better for you” is a marketing ploy, and McDonald’s must need help. Although its annual sales are $24 billion from its 14,000 outlets in the United States, Happy Meals have not been doing well.
Business analysts attribute declining sales since 2003 to the unsophisticated toys. Toys are the only reason kids want Happy Meals, but more parents are ordering adult meals and splitting them with the kids. But what if Happy Meals appear healthier?
Let’s be clear: McDonald’s is not a social service agency. It is a business. Its business interests come first. This means selling more food to more people more often, viewing food choice exclusively as a matter of personal responsibility and pretending that the company’s $1.3 billion annual marketing expenditure has no effect on consumer choice.
I suspect McDonald’s actions are attempts to appease Michelle Obama’s healthy eating campaign and perhaps to attract health-minded families to its outlets.
But surely the changes are also part of a calculated public relations effort to discourage other communities from enacting nutrition standards like those in San Francisco.
What McDonald’s actions make clear is the need for federal action to make it easier for people to make healthier choices for their kids. This means putting some curbs on marketing below-standard foods to kids and insisting that default kids menus be healthy.
If McDonald’s were serious about promoting kids’ health, it would offer default Happy Meals that meet San Francisco’s nutrition standards and advertise them to the hilt. Until the company does that, I’m reserving applause.

This article appeared on page G – 4 of the San Francisco Chronicle
I got several calls this week about a new study from the University of Washington arguing that because of the way foods are subsidized, it will cost everyone nearly $400 a year to follow the recommendations of the government’s MyPlate food guide.
The Seattle group calculates the cost of food per calorie. By this measure, the price of fruits and vegetables is exceedingly high compared to the cost of junk food. Fruits and vegetables do not have many calories for their weight.
The Commerce department tracks the indexed price of foods. Its data show that the indexed price of fresh produce increased by 40% ince 1980 whereas the price of sodas and processed foods has declined by 10-30%. (The easiest place to see their charts is in New York Times articles from a couple of years ago. Click here and also here).
USDA economists have produced a similar chart:
Other USDA economists, however, argue that price trends for fruits, vegetables, and junk foods are really no different, and that the data shown in the figure overstate the apparent difference.
Nevertheless, the Seattle paper got a lot of attention, and rightly so. One of my calls was from David Freeman of CBS News who said he was hearing lots of complaints that the study promoted a “nanny state” because it blamed bad eating habits on the government. My quotes:
“It’s a common misconception that food choices are solely a matter of personal responsibility,” Dr. Marion Nestle, professor of nutrition, food studies, and public health at New York University and an outspoken critic of the fast food industry, told CBS News. “People are hugely influenced by the price of food. If you don’t have any money and go into the store to buy some fresh fruits, you might decide that it’s cheaper to have a couple of fast food hamburgers.”
And those who can afford healthy food may lack the time or the necessary food-preparation skills, Dr. Nestle said.
Government-sponsored cooking classes and kitchen equipment may not be in the offing. But Dr. Monsivais and Dr. Nestle agreed that federal agriculture policies could do more to encourage healthy eating. For example, some of the federal farm subsidies now directed to producers of corn, soybeans, and other crops used to make fast and processed foods could be redirected to growers of fruits and vegetables.
“What’s the matter with that?” Dr. Nestle said. “I can’t think of a thing.”
I’m in the midst of working on the copy-edited manuscript of my forthcoming book with Malden Nesheim Why Calories Count: From Science to Politics (University of California Press, March 2012) and spending every minute I have on it. So I’m going to take some shortcuts on the blog this week and deal with some questions I’ve been asked recently.
One is right on the topic of the book:
Q. Could you address the 2,000 calorie a day number (both its history and speculate on how an individual can arrive at a more personalized amount)? Short of metabolic testing (and I read conflicting opinions on that, too), it seems rather difficult to figure out how much I should be eating.
A. Nothing could be easier, and here’s a preview of the kind of thing that will be in this book (with footnotes, of course):
If you look at a food label, you will see ingredient contents compared to a 2,000-calorie average diet: “Percent Daily Values are based on a 2,000 calorie diet. Your daily values may be higher or lower depending on your calorie needs.”
Here’s the history of where that came from:
The FDA wanted consumers to be able to compare the amounts of saturated fat and sodium to the maximum amounts recommended for a day’s intake—the Daily Values. Because the allowable limits would vary according to the number of calories consumed, the FDA needed benchmarks for average calorie consumption, even though calorie requirements vary according to body size and other individual characteristics.
From USDA food consumption surveys of that era, the FDA knew that women typically reported consuming 1,600 to 2,200 calories a day, men 2,000 to 3,000, and children 1,800 to 2,500. But stating ranges on food labels would take up too much space and did not seem particularly helpful. The FDA proposed using a single standard of daily calorie intake—2,350 calories per day, based on USDA survey data. The agency requested public comments on this proposal and on alternative figures: 2,000, 2,300, and 2,400 calories per day.
Despite the observable fact that 2,350 calories per day is below the average requirements for either men or women obtained from doubly labeled water experiments, most of the people who responded to the comments judged the proposed benchmark too high. Nutrition educators worried that it would encourage overconsumption, be irrelevant to women who consume fewer calories, and permit overstatement of acceptable levels of “eat less” nutrients such as saturated fat and sodium. Instead, they proposed 2,000 calories as:
- consistent with widely used food plans
- close to the calorie requirements for postmenopausal women, the population group most prone to weight gain
- a reasonably rounded-down value from 2,350 calories
- easier to use than 2,350 and, therefore, a better tool for nutrition education
Whether a rounding down of nearly 20 percent is reasonable or not, the FDA ultimately viewed these arguments as persuasive. It agreed that 2,000 calories per day would be more likely to make it clear that people needed to tailor dietary recommendations to their own diets. The FDA wanted people to understand that they must adjust calorie intake according to age, sex, activity, and life stage. It addressed the adjustment problem by requiring the percent Daily Value footnote on food labels for diets of 2,000 and 2,500 calories per day, the range of average values reported in dietary intake surveys.
As to how many calories you personally need, I think they are too difficult for most people to count accurately to bother. The bottom line: If you are eating too many, you will be gaining weight.
The best advice I can give is to get a scale and use it. If your weight starts creeping up, you have to eat less.
The book will go into far more explanation of such issues but for that you will have to wait until March.
