Research paper of the day: Is Psychological Well-being Linked to the Consumption of Fruit and Vegetables?


Could it be that the best way to combat the epidemic of depress that we find in moder society is just to eat more vegetables?  This new paper from the National Bureau of Economic Research argues it might. 

Humans run on a fuel called food. Yet economists and other social scientists rarely study what people eat. We provide simple evidence consistent with the existence of a link between the consumption of fruit and vegetables and high well-being. In cross-sectional data, happiness and mental health rise in an approximately dose-response way with the number of daily portions of fruit and vegetables. The pattern is remarkably robust to adjustment for a large number of other demographic, social and economic variables. Well-being peaks at approximately 7 portions per day.

Well I think I am going to start eating way more fruits and vegetables, how about you?
