This Is Your Brain on Cars—Oh, and Your Lungs and Heart and Gut, Too
Gerontologists in a laboratory at the University of Southern California exposed a group of mice to the same atmospheric conditions that humans encounter when driving along the freeway. Horrifyingly, they discovered that the mice’s brains showed the kind of swelling and inflammation associated with diseases such as Alzheimer’s. The researchers didn’t super-dose to get these results: The mice were exposed to freeway air for the equivalent of 15 hours a week -- less than the 18.5 hour average Americans spend in their cars. Jokes aside about getting those darn mice off the road, the study suggests that driving less may reduce our risk of brain damage.

Food Deserts: Another Way the Deck Is Stacked Against Car-Free Americans
Slate has posted this map to illustrate the concentration of "food deserts," where large numbers of people don't have access to fresh food. The USDA considers households more than a mile from a supermarket and without access to a car to be in food deserts, often with only convenience-store junk food for nourishment. In 2009, the agency found 2.3 million of these households. Here, Slate shows the preponderance of those households in Appalachia and the Deep South, and on Indian reservations.

NYC MDs: Tackling Obesity Takes Systemic Change and Safer Streets
So it looks like the lasting media image from last week's City Council hearing on bike policy will be Marty Markowitz's string of non-sequiturs sung to the tune of "My Favorite Things." The routine was allowed to proceed even though committee chair Jimmy Vacca began the hearings with a call for decorum at all times. (Maybe that's what prompted NYC Greenmarket founder and car-free Central Park pioneer Barry Benepe to observe, "The entire process appeared to be staged for the benefits of the loudmouths.")

APTA Report Prescribes Public Transport to Improve Public Health
A new report written by the Victoria Transport Policy Institute's Todd Litman for the American Public Transit Association [PDF], the trade organization for the nation's transit agencies, reminds us that one of the most valuable benefits of transit is to our health. Summarizing the state of research in the field, "Evaluating Public Transportation Health Benefits" lays out the basic fact that increasing transit use is an easy way of preventing thousands of unnecessary deaths each year.

Our Waistlines Are Expanding In Sync With Our Car-Dependence
Two reports released last week underscored the increasing severity of America's obesity epidemic. And the eye-opening findings add to the mounting evidence that stopping the spread of obesity and its attendant health risks will require changes to the nation’s transportation system as surely as it demands altering our diets.

Car-Dependent States Hit Hardest by Obesity Epidemic
Transportation is a public health issue. As profiled in the recently released report from the Trust for America's Health, "F as in Fat," obesity rates continue to rise across the nation, increasing the risk of serious health problems like diabetes and hypertension. To solve the obesity epidemic, the data suggest, we need to rethink our dependence on the automobile.
