I’m getting caught up on my journal reading and didn’t want to miss this one.

The journal Childhood Obesity has a special issue of articles related to Michelle Obama’s Let’s Move! campaign.  Mrs. Obama wrote the foreword.

Here are some selections:

Dietary sodium continues to generate much talk but little action.

The CDC issued a recent Vital Signs report on dietary sodium with this graphic:

In translation from the data tables:

• 90% of Americans consume too much salt.
• 44% of salt comes from 10 foods: breads and rolls, cold cuts and cured meats, pizza, poultry, soups, sandwiches, cheese, pasta dishes, meat dishes, and snacks.
• 65% of salt comes from retail processed foods.
• 25% comes from food served at restaurants.
• 10% comes from salt added at the table.
• 10% occurs naturally in foods.
• $20 billion a year is the cost of salt-related chronic disease.

The bottom line?  Americans would be better off eating less salt.

But from the standpoint of the food industry, reducing dietary sodium is a big problem.  See, for example,  FoodNavigator-USA.com‘s recent articles about sodium in foods and health:

Sodium reduction: The science, the technology… and the business case It’s expensive, risky, and difficult, but manufacturers have made huge progress on sodium reduction in recent years. But how much further can they go, and where is the ROI if consumers are at best indifferent to their efforts, or at worst downright suspicious?..

Marty Gitlin and Topher Ellis, The Great American Cereal Book, Abrams 2011.

I love cereal boxes, especially ones with egregious health claims, and I have a small collection dating back ten years or so.  I also, courtesy of Kellogg, have facsimiles of the complete set of Rice Krispies, All-Bran, and Froot Loops, dating back to the first year they were produced.   So I’m delighted to find this history of U.S. breakfast cereals, organized alphabetically by era starting in the 1860s, illustrated with pictures of each.  A encyclopedic nostalgia trip!

Aaron Bobrow-Strain, White Bread: A Social History of the Store-Bought Loaf, Beacon Press, 2012.

Bobrow-Strain organizes this books by dream categories: dreams of purity and contagion, control and abundance, health and discipline, strength and defense, peace and security, resistance and status.  White bread does all this?  Indeed it does in this story of how “white bread became white trash.”  He begins by asking, “Is this stuff even food?”  He ends with the whole wheat phenomenon and “yuppie bread.”  This is entertaining history and an example of food studies in action: using food to talk about important issues in history and contemporary society.

Jane Brody, Personal Health, March 20: Calories are everywhere yet hard to track

The human body has a very complex and redundant system to make sure the brain gets the sugar calories it needs to function, Dr. Nestle and Dr. Nesheim explain in their book. At least 100 different hormones, enzymes and other chemicals — with more likely to be discovered — act to regulate appetite and to assure that people eat enough to maintain brain function.

But it is these very systems that go into overdrive during starvation (translation: a reduced-calorie diet), making it so difficult for people to lose weight.

Mark Bittman, Opinionator, March 21: Is a calorie a calorie?

Ultimately, the calorie is political: marketing affects instinct, and Nestle and Nesheim really shine in their analysis in this realm. (Their slogan: “Get organized. Eat less. Eat better. Move more. Get political.”)

When I asked Nestle what she would do, given that people in the United States were obviously eating too many calories and that the resulting excess weight was costing all of us life years and money, she answered quickly: “We need a farm bill that’s designed from top to bottom to support healthier diets, one that supports growing fruits and vegetables and making them cheaper.

We need to fix school lunches so they’re based on fresh foods, and fix food assistance programs so people have greater access to healthier foods.”

Every Tuesday I answer a question about food or nutrition in NYU’s student newspaper, the Washington Square News.  My deal with the dining editor is that she sends one question a week and I do the best I can with it.  The questions reflect the kinds of things that NYU undergraduates want to know.

This week, the question is about cooking chicken:

Q.  What are the more cheap and healthy ways for students to buy and cook chicken? What are the health differences between chicken breast/legs/etc.?

A.  Let me answer your second question first.  Chicken is a good source of protein and other nutrients.  Most of the nutritional differences between one part and another are too small to bother mentioning.  The one useful difference is that dark meat has a bit more saturated fat and cholesterol than white meat.  Even so, most of the fat in chicken is in the skin.  Worried about fat?  Remove the skin.

The important nutritional differences result from preparation.  If you add fat during preparation, you are also adding calories (fat has 9 calories per gram as compared to 4 for protein or carbohydrate).

The healthiest way to cook chicken is to bake it in the oven or stir fry it with vegetables.  Put the parts in a baking pan, rub some olive oil on them, and surround them with plenty of garlic, lemon, carrots, or whatever you like.  Bake at 350° until brown.

Buy whole chickens so you aren’t paying someone else to cut it up for you.  Cutting a chicken is easy and YouTube has plenty of videos that explain how to do it.

The cheapest chicken is industrially produced, meaning that the chickens are raised in huge flocks indoors under crowded conditions, treated with antibiotics to prevent illness and promote rapid growth, and are ready to slaughter six weeks after hatching. 

If you don’t want to eat chicken raised this way, you should look for birds that were raised free-range without antibiotics and are Certified Organic, kosher, or halal—if you value such things.   You will have to pay more for such meat but it will taste better. 

You will be supporting a food system that is healthier for chickens, people, and the planet.

Jonathan Deutsch and Natalya Murakhver, editors, They Eat That?  A Cultural Encyclopedia of Weird and Exotic Food from around the World, ABC-CLIO, 2012.

The editors, both graduates of my NYU department, got their students, colleagues, and friends to write short essays about nearly 100 foods considered weird, at least by someone.  The list includes foods that are anything but weird in other cultures—seitan, durian, nettles, haggis, huitlaloche, vegemite, but also those hardly ever available to even the most serious eaters.  On that list I would put camel, cavy, iguana, and walrus flipper.  As for what I would eat, stinky cheese, yes.  Urine, no way.  The entries put the foods in cultural context and provide references.  Most come with recipes.  This book is fun.

Tracie McMillan, The American Way of Eating: Undercover at Walmart, Applebee’s, Farm Fields and the Dinner Table, Scribner 2012.

McMillan followed the footsteps of Barbara Ehrenreich (Nickel and Dimed) and went to work at low wage jobs.  She has plenty to say about how hard it is to do them and how little they pay; she provides balance sheets to prove it.  Like Ehrenreich, she’s a good writer and her stories are compelling.  Eating well in America, she says, is difficult—bordering on impossible—for people who don’t have much money.

Atina Diffley, Turn Here Sweet Corn: Organic Farming Works, University of Minnesota Press, 2012.

I blurbed this one, with much pleasure: “Turn Here Sweet Corn is an unexpected page-turner.  Atina Diffley’s compelling account of her life as a Minnesota organic farmer is deeply moving not only from a personal standpoint but also from the political.  Diffley reveals the evident difficulties of small-scale organic farming but is inspirational about its value to people and the planet.”  The book comes with an insert of glorious photographs illustrating the history she recounts.  The political?  The Diffley’s fought to keep an oil company from running a pipeline through their property—and won.

David Hanson and Edwin Marty, Breaking Through Concrete: Building an Urban Farm Revival, University of California Press, 2012.

Wonderfully photographed visits to a dozen urban farms all over America from Seattle (P-Patch) to Brooklyn’s own Annie Novak’s Eagle Street.  The authors asked hard questions and got honest answers.  This is a great resource for anyone who wants to get started, and the beautiful farms and farmers are well worth a look.

Jennifer Cockrall-King, Food and the City: Urban Agriculture and the New Food Revolution, Prometheus Books, 2012.

Cockrall-King went international.  She visited cities in the U.S., England, France, Canada, and Cuba to see what urban farmers were doing to create alternative food systems.  They are doing plenty.  This looks like a great excuse for ecotourism, dropping by, seeing for yourself, and getting to work.
