A Healthy Take
Commuters exposed to
pollution in car
If you live a relatively healthy life
and don’t smoke, chances are the unhealthiest part of your day is your
daily commute, researchers say. A study by
(www.usc.edu) and the California Air Resources Board (www.arb.ca.gov) found
that up to half of
residents’ total exposure to harmful air pollutants occurs while people
are traveling in their vehicles. Although the average driver in
spends only about 6 percent of their day on the road, that period of time
accounts for between 33 percent and 45 percent of their total exposure to
diesel and ultrafine particles (UFP), the researchers say.
“Urban dwellers with long commutes are
probably getting most of their UFP exposure while driving,” says Scott
Fruin, assistant professor of environmental health at USC. Ultrafine
particles are of concern because they tend to be more toxic than larger-size
particles, he says. “Shortening your commute and spending less time in the
car will significantly reduce your total body burden of harmful

The herb rosemary contains an ingredient
that fights off damage to the brain. The active ingredient in rosemary can
protect the brain from stroke and neurodegenerative conditions such as
Alzheimer’s, and also from normal aging, a collaborative group of
researchers at the Burnham Institute for Medical Research (www. burnham.org)
say. The ingredient, carnosic acid, protects the brain cells from free
radicals. The findings were originally reported in The Journal of
Neurochemistry and Nature Reviews Neuroscience.
Rosemary comes from a shrubby evergreen
bush with needlelike leaves. It has trusses of flowers that can be white,
pink, purple or blue. Rosemary derives its name from the Latin rosemarinus,
which translates as “dew of the sea.” Rosemary has a long history as a
memory aid. It was also used in the past at weddings to symbolize love and
