Good food nation
MIT researchers think America's obesity epidemic can be reversed via ‘foodsheds,’ in which healthier, more affordable food is produced and consumed regionally.

In the last three decades, childhood obesity in the United States has become a massive public-health problem. According to the Centers for Disease Control, between 1980 and 2006 the percentage of obese teenagers in the United States grew from 5 to 18, while the percentage of pre-teens suffering from obesity increased from 7 to 17. Such children often become overweight adults, leaving themselves especially susceptible to heart illness, Type 2 diabetes, strokes, and some forms of cancer.
These weight problems do not simply stem from a lack of willpower, according to Dr. Tenley Albright, director of MIT’s Collaborative Initiatives program, which uses systems analysis to study broad social issues. Albright is a Harvard-educated surgeon who, two years ago, helped organize an interdisciplinary group of about 10 researchers, from MIT and Columbia University, specifically to analyze the causes of child obesity. Aided by a grant from the United Health Foundation, the team scoured medical and economic data, and consulted with medical researchers, economists and policy-makers, before releasing an initial October 2008 report.
The group’s conclusion: Obesity is widespread due to our national-scale system of food production and distribution, which surrounds children — especially lower-income children — with high-calorie products. “The problem lies not just in a child, but the whole environment around a child,” says Albright. “To end obesity, we need to produce healthier, more accessible, more affordable food.” As Albright notes, 90 percent of American food is processed — according to the United States Department of Agriculture — meaning it has been mixed with ingredients, often acting as preservatives, that can make food fattening.
