Expanding portion sizes in the Joy of Cooking

Brian Wansink’s latest paper is an analysis of the increasing size of servings and meals through multiple editions of the classic cookbook, Joy of Cooking. These, he finds, have increased by 35%.  My former doctoral student, Lisa Young, looked at how portion sizes began to balloon in the early 1980s in parallel with increasing calories in the food supply (from 3,200 to 3,900 per day per capita) and with rising rates of obesity.  She showed how readers using identical recipes were instructed to make far fewer cookies in newer editions of the Joy of Cooking and wrote about this phenomenon in her book, The Portion Teller.

I wrote about this last year in a letter to the New York Times: “To the Editor: I could not resist looking up the calories for the gorgeous chocolate chip cookie recipe given on July 9. That recipe calls for about 4 pounds of ingredients to make only 18 cookies, each of which runs 500 calories — one quarter of the amount needed by most people for an entire day. I’d call one of those cookies lunch or share it with three friends. By the way, a similar recipe in the 1975 “Joy of Cooking” made 45 cookies with just half the ingredients. These would be just under 100 calories each.”

The point of all this: larger portions have more calories! And you need no further explanation for rising rates of obesity.

Update February 18: Wansink is a professor at Cornell, and the Cornell Chronicle did a story on it.

The irony of too little and too much food

Surely, this collection of items is nothing if not ironic.  The International Food Policy Research Institute (IFPRI) has issued its 2008 Global Hunger Index, which maps 33 countries with alarmingly high rates of hunger.  And then we have Taco Bell’s new Big Bell Box; it racks up 1670 calories with the drink and more than 3 grams of sodium (about 7 grams of salt).  We also have the Heart Attack Grill, which I guess is not really a joke.

I thank Andy Bellatti and Hugh Joseph for pointing these out (I think).

No end to supersizing

Here’s Lisa Young’s MSNBC summary of her latest observations of what fast food chains are doing about portion sizes–the same or bigger, in a word. If you want to read the article on which it’s based, look under Publications. Enjoy (?)

Better Nutrition Labels?

Today’s question (see Vending Machines post): “I was looking at the Nutrition Facts Label on a bag of carrots today…If I read this label and compare it to packaged foods, the carrots really don’t look all that healthy. And yet I know they are. I have the same experience with apples and with other fruits and vegetables. What needs to be added and changed on the Nutrition Facts panel so that this makes more sense? Has anyone done a blind study of nutrition labels, having people compare them side-by-side and see which food they believe is more healthy without knowing what the food is, but from the label alone?”

Response: When Congress passed the nutrition labeling act of 1990, which mandated Nutrition Facts labels on packaged foods, the FDA created a bunch of possible designs and tested them on consumers. The result: nobody understood any of the designs. The FDA chose the one that consumers least misunderstood. In What to Eat, I devote two chapters to explaining food labels, one for Nutrition Facts, and one for Ingredients. The FDA has a lengthy site to teach the public to understand food labels. I think the ingredient list tells you more about the real nutritional value of foods than the Facts part. My rule, only somewhat facetious, is to never buy foods that have more than 5 ingredients. The more processed a food is, the more ingredients it is likely to have (to cover up the losses), and the lower its nutritional quality. Fresh and some frozen foods have only one ingredient: carrots, apples, broccoli, beans. The most important thing I’d change on food labels is the calories. The FDA proposed five years ago to require packages likely to be consumed by one person to display the total number of calories on the front panel, rather than listing calories per serving, which makes the calories appear lower than they are. What happened to that excellent proposal? It disappeared without a trace (the packaged food industry loathes the idea). It’s tricky to figure out what else an ideal food label would display. Any ideas? Forward them to the FDA (and post them here, of course).

McDonald’s Portions

The New York Times business reporter, Andrew Martin, starts a new column on the food and beverage industries today with an article on McDonald’s Portion Sizes and the introduction of Hugo drinks to temporarily replace the company’s phased-out Supersize portions. Mr. Martin’s article draws on a study on McDonald’s promises versus actions that I did in collaboration with my former doctoral student, Dr. Lisa Young, just published in the Journal of Public Health Policy. If you look at the comments to my previous entry on Hugo drinks, people do love getting 42-ounce drinks for as little as 69 cents. And, of course, they can fill those cups with water if they like.
