Smog has been linked to heart problems and even death, and new research by the U.S. Environmental Protection Agency begins to explain why.
Researchers found that healthy young adults who have been exposed to ozone – which is a major component of smog – experience physiological changes that could be linked to heart ailments in vulnerable populations, such as elderly people with cardiovascular disease. Additionally, the study “provides a plausible explanation for the link between acute ozone exposure and death,” lead author Robert B. Devlin said in a statement.
The study has special implications for Californians, who are exposed to some of the highest ozone levels in the country.
Of the 10 regions in the country with the most ozone pollution, nine are in California, with Los Angeles-Long Beach-Riverside topping the list, according to the American Lung Association.

But coming in a close second (at least here at the health desk) was the call for regulating sugar in the same way alcohol and tobacco are. The argument was made by UC San Francisco researchers in the journal Nature. They laid out the science that sugar is behind many of the chronic maladies we see today–diabetes, heart disease and high blood pressure.
Today FDA Commissioner Margaret Hamburg was a guest on KQED’s Forum. Host Michael Krasny asked her if sugar should be removed from the FDA’s “GRAS” category–that’s for Generally Recognized as Safe. Not surprisingly, the Commissioner did not announce imminent action. She said she did have a chance to “look quickly at the initial report” and that “we’ll look very seriously at any new data that’s presented.” Continue reading
