If you want to keep your mind as healthy as possible as you age, pay attention to your waistline. Evidence is accumulating that excess weight is linked to mental decline in older years.
A recent study found that postmenopausal women lost one point from their scores on a standard memory test for every point increase in their body mass index, indicating that obesity is linked to a decline in memory and brain function with aging.
A 2008 study found similar results. People with the greatest central fat accumulation had almost a three-fold higher rate of dementia 36 years later than those with the least amount.
