You don't have to eat a burger for it to be bad for your health. The exhaust from cooking them is a major contributor to air pollution.
Charbroiling about a dozen burgers creates as much polution as driving a diesel truck for over 140 miles. That's a conservative estimate from UC Riverside researchers.
They're developing new ways to filter cooking exhaust. The study should be complete by the end of the year.
New restaurant regulations are also in the works. If the technology catches up, larger establishments could be forced to install new air filters.
