What was once considered a vain preoccupation, the quest to drop 5 (or 50) pounds has swept America in a call-to-arms, complete with militant nutritionists who bark out commands to "put down that cookie dough and pick up a carrot!" and refuse to acknowledge the financial burden of maintaining a healthy diet. As a nation we have never fought so hard to lose, but we rarely question why so many of our ranks have fallen.
A new study sheds light on the high cost of the battle and proves that loosing a few inches around the waist is much harder when you have to tighten your belt. Adam Drewnowski, Director of the University of Washington's Center for Public Health and Nutrition and advocate-extraordinaire for struggling single moms everywhere, recently conducted a study in Seattle which reveals a 20 percent increase in the cost of healthy food between 2004 and 2006; over and above the 5 percent overall increase of food. Simultaneously the cost of junk food dropped.
Drewnowski argues that the relationship between poverty and obesity is causal, after having found in another study that the major mechanism behind this link is the inverse relationship between energy-density (MJ/kg) and energy-cost (US dollars/MJ) of food. The premise is simple, confirming what any struggling college student will tell you in line at the university food court: two slices of pizza for $2.50 will go further than an $8.00 salad.
While there is no question that everyday life in America is a minefield littered with pressures to eat poorly, the lower socio-economic class as a subgroup stands out as a nutritional black hole. Fast-food restaurants are concentrated in poorer neighborhoods and ads continually remind residents that they can "Feed the Family for Under $4 Each" at KFC. The USDA's Healthy Eating Index, which measures the nutritional quality of an individual's overall diet, produces consistently high scores for wealthy and low scores for poor individuals. As a quantifying example, 10% of high-earning adults eat 3 or more servings of whole grain products per day and fulfill their fruit and vegetable requirements while only 5% of low-earning adults do so."
Drewnowski and other nutritionists claim that obesity in the US is a socioeconomic burden born by those living in low-income communities where a "toxic nutritional environment" (a phrase coined by Marion Nestle) is created and re-created. "It's not a question of being sensible or silly when it comes to food choices," he says. "It is the opposite of choice. People are not poor by choice, and they become obese primarily because they are poor."
Therefore, as a former struggling college student (hell, as a struggling college graduate) I have this to say to those tiny, annoying Pomeranians who bark and growl from the nutrition columns and early morning news shows--bite me.
