"Piomelli's previous studies identified how oleic acids from fats are transformed into a compound called oleoylethanolamide (OEA) in the upper region of the small intestine. OEA sends hunger-curbing messages to the brain to increase feelings of fullness. In elevated levels, OEA can reduce appetite, produce weight loss and lower blood cholesterol and triglyceride levels.
Piomelli and McGaugh discovered that OEA also causes memory consolidation, the process by which superficial, short-term memories are transformed into meaningful, long-term ones."
Why is this the case is also fascinating:
"OEA is part of the molecular glue that makes memories stick," Piomelli said. "By helping mammals remember where and when they have eaten a fatty meal, OEA's memory-enhancing activity seems to have been an important evolutionary tool for early humans and other mammals.""
Interesting! Three fast takes: 1. I definitely agree that some fat in a meal makes you feel full faster. And 2. it might explain why many have pleasant memories of eating out. If more fat, you may remember it more. and 3. might eating some (good fat) improve memory for tests etc?
