Not that I am not totally in favor of hearing that green tea, red wine, and chocolate (three of my favourite things!) are basically the keys to living forever, but I’m not sure this study didn’t just run away with itself a little bit.
The author postulates that the amount of chocolate a country consumes is strongly correlated to the number of Nobel prizes it has won, a possible indicator of higher cognitive function. But could it not also be related to the fact that chocolate has for centuries been a luxury food, and the higher the consumption per capita, likely the higher a country’s GDP, which would leave more resources for education and for winning those shiny Nobel prizes.
Either way, I will still eat a lot of chocolate, drink my fair share of red wine, and start my day with a hot mug of green tea.
