Researchers have linked eating baked or broiled fish with brain health later in life—but say it's not about the omega-3 fatty acids.
The findings, published online in the American Journal of Preventive Medicine, add to growing evidence that lifestyle factors contribute to brain health later in life.
Scientists estimate that more than 80 million people will have dementia by 2040, which could become a substantial burden to families and drive up health care costs, according to senior investigator James T. Becker, professor of psychiatry at the University of Pittsburgh School of Medicine.
Some studies have predicted that lifestyle changes such as a reduction in rates of physical inactivity, smoking, and obesity could lead to fewer cases of Alzheimer’s disease and other conditions of cognitive impairment in the elderly.
The antioxidant effect of omega-3 fatty acids, which are found in high amounts in fish, seeds, and nuts, and certain oils, also have been associated with improved health, particularly brain health.
