Food For Thought

 . The nervous system consumes more glucose than most other parts of the body; effortful mental activity is especially expensive in its demand for glucose. When involved in difficult cognitive reasoning or engaged in a task that requires self-control, your blood glucose levels drop. This is similar to a runner using stored muscular glucose when sprinting. Thus to handle self-control, ego depletion, etc, ingesting glucose is one way effective startegy. This restores the available sugar in the brain and prevents deterioration of performance, judgment, decision-making, etc. Research (Daniel Kahneman 2012) has shown that people make better decisions after eating some food, and poorer decisions when hungry.
