Eating for Optimal Performance

I frequently post stories on athletes eating to optimize their performance.  I wonder, why is fuel for daily performance only important for athlete's?  Most of us are professional's at something.  We have personal lives that also need to be considered.  We all perform in different ways all day, every day.  Why shouldn't everyone optimize their diet for optimal performance?  Is your diet optimized?  Is your health optimized?  Is your performance optimized?
