Fish may protect the brain from air pollution's effects

Older women who eat more than one to two servings a week of baked or broiled fish or shellfish may consume enough omega-3 fatty acids to counteract the effects of air pollution on the brain, according to a new study. Ironically, one of the study limitations actually makes it even more relevant to the active-aging industry: the researchers were only able to examine exposures to later-life air pollution, not early or mid-life exposures. That means the benefit may still be seen with dietary changes for residents and members.
