The objective of the study was to examine whether intake of fats are associated with the risk of dementia. The dietary habits of 5,395 subjects with normal cognition were assessed over a six year period.

The study found:
(a) Higher fat consumption was associated with a 7% reduction in dementia.
(b) Higher saturated fat consumption was associated with a 9% reduction in dementia.
(c) Higher cholesterol consumption was associated with a 7% reduction in dementia.
(d) Higher polyunsaturated fat consumption was associated with a 5% increase in dementia.

The data from the study reveals that higher saturated fat and cholesterol consumption is associated with a lower risk of dementia.
