> I have a hard time believing diet has a statistically significant impact on cognitive performance - excluding caffeine or other stimulants of course
Oh for me it's just the opposite:
Caffeine makes me jumpier, but I'm not at all sure it improves my cognitive performance. Do you have any evidence caffeine has positive impact on cognitive performance?
I'm pretty sure eating healthy improves the clarity of my thinking. When I was young, I'd eaten a bar of chocolate for lunch a couple of times when short of time during a go tournament. This has invariably been a terrible idea and worsened my performance.
