Good foods --> blood sugar steady and feel-good brain chemicals  --> good mood

==================

Foods can boost energy by supplying calories, by pushing your body to burn calories more efficiently, and, in some cases, by delivering caffeine. 

For a better mood, the best foods are those that help keep your blood sugar steady and trigger feel-good brain chemicals.
