Why Fat?
A diet high in saturated fat has been shown in studies to impair a wide range of learning and memory functions; a possible reason for this could be constricted blood flow to the brain.

Why Alcohol?
Alcohol's negative effects on the brain have been well documented ? prolonged alcohol abuse can cause the brain to atrophy, and it impairs activity in the brain receptors necessary for memory and learning.
