These people might also look to change their diet, eating foods rich in

inflammation-limiting antioxidants, like brightly colored fruits and

vegetables, or dark chocolate. She recently began feeding commercially

available chocolate rich in polyphenols, a class of natural

antioxidants, to treat inflammation ravaging the hearts and minds of mice.

Scientists have known that air pollution can impair airways and

blood vessels. The emerging surprise is what it might do to the

brain. Increasingly, studies have been highlighting

inflammation-provoking nanopollutants as a potential source of

nerve cell damage. ~Science News

*excerpt:*

When Lilian Calderón-Garcidueñas recruited children for a study probing

the effects of air pollution, Ana was just 7. The trim girl with an

above-average IQ of 113 " was bright, very beautiful and clinically

healthy, " the physician and toxicologist recalls.

But now Ana (not her real name) is 11. And after putting her and 54

other children from a middle-class area of Mexico City through a new

battery of medical and cognitive tests, Calderón-Garcidueñas found that

something has been ravaging the youngsters' lungs, hearts --- and,

especially troubling, their minds.

Brain scans and screening for chemical biomarkers in the blood pointed

to inflammation affecting all parts of the brain, says

Calderón-Garcidueñas, of the National Institute of Pediatrics in Mexico

City and the University of Montana in Missoula. On MRI scans, white

spots showed up in the prefrontal cortex. In the elderly, she says, such

brain lesions tend to denote reduced blood flow and often show up in

people who are developing dementias, including Alzheimer's disease.
