Mark Winne discusses SNAP reform

Long-time anti-hunger and community food security activist Mark Winne has a new essay on the Supplemental Nutrition Assistance Program (SNAP).  Winne is passionate about protecting the program from the deep cuts proposed in the House of Representatives and eloquent about the hardship SNAP participants face in these hard economic times.

And yet, Winne includes the following strident call for reform and improvement of SNAP:
Whether we have more food stamp spending or less begs the question of why such a major act of social policy that nobody, including the recipients, seems to like, continues unreformed and unevaluated. With a national poverty rate locked at 15 percent and a near-poverty rate bringing the combined numbers to well over 30 percent, food stamps provide some relief but no solutions. With overweight and obesity affecting 65 percent of the population and eclipsing hunger as America’s number one diet-related health problem, food stamps do little to encourage healthy eating and less to discourage unhealthy eating. And with high unemployment, low wage jobs, and few prospects for growth – other than big box stores and casinos – leaving the economy stuck in neutral, food stamps $70 billion in federally generated buying power helps Kraft Foods (food stamps are 1/6 of its sales), but nearly nothing to infuse local economies with new energy.

But the anti-hunger orthodoxy that SNAP is a vital part of the nation’s safety net and must never be altered goes unchallenged. Whenever an innovation is proposed, e.g. Mayor Bloomberg’s request to prohibit the use of food stamps to purchase sugary soft drinks, the program’s pit bull defenders bare their teeth threatening to rip the limbs off heretics who might modify even one of SNAP’s holy sacraments. It may be that they are in bed with Wal-Mart and others who have tragically dumbed-down American wages and whose workers are subsidized by the food stamp program, or it may be that they are riveted to the notion that they are all that stand between a modicum of food sufficiency and mass starvation. Either way, the tenaciousness of their enterprise, which opposes food stamp change at any cost, is only matched by an equally fervent brand of conservatism embodied by the Tea Party. The result: A program now more than 50 years old remains largely unchanged even though the nation that it helps feed has changed in myriad ways.

Imagine a corporation or major private institution that did not conduct research and development, kept the same product line for generations, and never engaged in strategic thinking. That enterprise would be out of business (or subsidized by the federal government).
It's something to think about.

Like Winne, I think it would be fine for USDA to use its existing authority to permit pilot innovations that would change the definition of "food" under SNAP to exclude sugar sweetened beverages such as soda. The New York City proposal was designed to appeal only to public health nutrition advocates and did not do well at building bridges with anti-hunger advocates.  Yet, I think both public interest traditions should support such a pilot.  The anti-hunger advocates say the proposal is stigmatizing, but I see no evidence that SNAP participants actually would mind.  Remember, low-income parents, just like all parents, work hard to choose healthy foods in a rough marketing environment, and they may find the restriction helpful as they discuss food and beverage choices with their children in the aisle of the grocery store.  Congress has to draw the line between "food" and "non-food" somewhere, and it makes sense for USDA to use pilot studies to help Congress figure out the best way to do so.  If the pilot finds that the proposed reform increases stigma, reduces program participation, or damages food security, the proposal should be dropped.  But, quite possibly, the opposite will happen.  Anti-hunger advocates may be stuck in the way things have always been, overlooking an opportunity that could be appealing to program participants and politically popular with the public at large.

I once interviewed Winne for this blog, shortly after he wrote his book, Closing the Food Gap.  Winne's new book is Food Rebels, Guerrilla Gardeners, and Smart Cookin’ Mamas.

Link between television and weight

In the current issue (.pdf) of the magazine Tufts Nutrition, Jacqueline Mitchell describes recent research on television viewing and weight status.
Americans spend an average of more than 150 hours a month in front of the television — that’s six days—and never mind other sedentary hours we spend with computers or mobile devices. As our screen time has exploded, so has the national waistline. Two-thirds of adults are overweight, and childhood obesity has more than doubled in the last 20 years.

One reason obesity may be on the rise is that people who watch a lot of television may eat more, particularly pizza, soda and other fast foods, according to a recent Tufts study that evaluated 30 years of research linking TV viewing with weight gain. The paper, written by four students and their adviser, Robin Kanarek, Ph.D., interim dean of the Friedman School, was published online in the June 4 edition of Physiology and Behavior....  The research by Kanarek and the students—Rebecca Boulos, N13; Emily Vikre, N08, N13; Sophie Oppenheimer, N11, MPH11; and Hannah Chang, A10—also indicated that television can shape societal views about overweight and obese people.

Two communication strategies for reducing sugary drinks

First, I like the plain matter-of-fact tone of the federal government's MyPlate graphic. It paints a pleasant portrait of a healthy meal, and then underlines several key messages for consumers by stating them in blunt English.  One of the key recommendations is to "drink water instead of sugary drinks."

A reasonable person may add that one should drink water instead of sugary drinks most of the time, but the mainstream message of the dietary guidelines reflects the best judgement of scientists in this field.



Balancing Calories
  • Enjoy your food, but eat less. 
  • Avoid oversized portions. 
Foods to Increase
  • Make half your plate fruits and vegetables. 
  • Make at least half your grains whole grains. 
  • Switch to fat-free or low-fat (1%) milk. 
Foods to Reduce
  • Compare sodium in foods like soup, bread, and frozen meals and choose the foods with lower numbers. 
  • Drink water instead of sugary drinks. 
Second, in a new video from the Center for Science in the Public Interest (CSPI), public health marketers seek to both imitate and expose the emotive power of soda advertisements.  In the video, a family of polar bears endures the harsh effects of diabetes and learns that the soda advertisements offer only a false promise of happiness.  The video strays close to playing on guilt themes as motivation for healthy behaviors, but the polar bears are fundamentally sympathetic, and they take charge of their own lives in the nice ending. 

If you dislike the video's harsh imagery, I'd be interested to hear about it.  But I do think the beverage association spokesperson's rebuttal -- in a USA Today article -- rings false:
But ABA spokeswoman Karen Hanretty says, "CSPI is better at producing videos than they are doing math. People are drinking fewer calories from soda -- and have been for a decade -- so how can soda be to blame for rising obesity?" 
The basic message that it is better to limit sugary drinks is well-established and denying this with misleading trend statistics just makes the video look like the more serious party in this conversation.

Reuters: Washington soft on childhood obesity

From yesterday's long report by Duff Wilson and Janet Roberts at Reuters:
At every level of government, the food and beverage industries won fight after fight during the last decade. They have never lost a significant political battle in the United States despite mounting scientific evidence of the role of unhealthy food and children's marketing in obesity.
Lobbying records analyzed by Reuters reveal that the industries more than doubled their spending in Washington during the past three years. In the process, they largely dominated policymaking -- pledging voluntary action while defeating government proposals aimed at changing the nation's diet, dozens of interviews show.

Why Calories Count

Why Calories Count, the new book by Marion Nestle and Malden Nesheim, nicely bridges the world of food policy commentary and nutrition science. It offers a great counterpoint to the loud and untrustworthy bazaar of diet books, each blaming some simple villain for the obesity epidemic (too much carbs, too much fat, too little calcium, whatever).  Why Calories Count teaches a wealth of detail about how calories are measured and how their effects are studied.  It also tells great stories, from the history of nutrition science to the poignant service of wartime conscientious objectors who participated in a clinical study of human starvation.  If I were a graduate student in nutrition or public health, I would find this book inspiring as an eloquent and engaging secondary reading alongside a nutrition science textbook.  Strongly recommended.
