Five Pillars of Health

Health is being happy and maintaining a balance of exercise, diet, and sleep. The five pillars of health are nutrition, exercise, sleep, stress, and social. The pillar that I am personally the strongest at is probably sleep, because I sleep a lot.  I could probably improve in any of the four remaining pillars.  Something I want to learn more about regarding health is what types of foods do benefits to your body, for example what to eat before sports and to help keep you focused longer.
