Omega 3 & Brain Ageing (2007)
This study investigated omega 3 and brain ageing. An Italian study measured the blood levels of essential fats in 935 elderly Italians and compared these with their cognitive function, which ranged from normal cognitive function through to dementia. The researchers found those with the worst cognitive function, had the lowest level of essential fats, especially omega-3.
