AB Nutrients  are  substances  that  are  not  synthesized  in  sufficient  amounts  in  the  body  and  therefore  must  be  supplied  by  the  diet.  Nutrient  requirements  for  groups  of  healthy  persons  have  been  determined  experimentally.  The  absence  of  essential  nutrients  leads  to  growth  impairment,  organ  dysfunction,  and  failure  to  maintain  nitrogen  balance  or  adequate  status  of  protein  and  other  nutrients.  For  good  health,  we  require  energy-providing  nutrients  (protein,  fat,  and  carbohydrate),  vitamins,  minerals,  and  water.  Requirements  for  organic  nutrients  include  9  essential  amino  acids,  several  fatty  acids,  glucose,  4  fat-soluble  vitamins,  10  water-soluble  vitamins,  dietary  fiber,  and  choline.  Several  inorganic  substances,  including  4  minerals,  7  trace  minerals,  3  electrolytes,  and  the  ultratrace  elements,  must  also  be  supplied  by  diet.
