The Immortality Institute forums have some great discussion on nootropics. This one for instance: http://www.imminst.org/forum/index.php?showtopic=35751 http://www.imminst.org/forum/index.php?showtopic=35751 This comment in particular I thought was very thought-provoking: The MOST important tactic to prevent brain disorders: avoid fructose, and carb over-consumption. The brain degrades MUCH faster under the assault of a glucose-driven metabolism. It runs much cleaner -- metabolically speaking -- on fatty acids, which it can do up to approx 50% of its energy needs. I'd be curious to hear of other places on the web where people are discussing nootropics as it a very interesting area to me.
