Tired of being tired? Like your car, if your body is missing fuel or spark plugs, it won’t go very far.  The carbohydrates, fats and proteins in your diet are the fuels that provide energy and the vitamins and minerals are the spark plugs which allow you to burn this fuel.  Simply eating a “normal” diet may not be enough to maximize health.  Would you put the same gasoline in an Alpha Romeo as you would in a Lada?
