Editorial: Exercise is good for body and mind
The Pensicola News JournalThe UCLA study released last week shows the brains of obese older adults are on average 8 percent smaller than their more fit counterparts. The research was funded by the National Institute on Aging, the National Institute of Biomedical Imaging and Bioengineering, the National Center for Research Resources and the American Heart Association. It focused on 94 subjects, 70 and older, who were overweight or obese. Overweight patients lost 4 percent of the tissue in the frontal lobes of their brains when compared with peers of normal weight. But those who were obese had twice the brain loss — 8 percent less tissue — in the frontal lobes crucial to attention and planning.
