Type, not amount, of fat decreases cognitive function in women
A study of 6,000 women (all over 65) found that changes in cognitive function were reflective of the TYPE of fat - not the amount - that they ate.
Those who ate the most saturated fat (red meat, butter, etc.) had the worst overall cognitiion and memory over the 4 years they were tested.
Those who at the most monounsaturated fats (olive oil) had the best cognitive scores.
In addition, it's important to note that declines in cognitive function can increase the risk of dementia and Alzheimer's.
And it's never too late to start substituting your bad fat for the good stuff!
