Why is the GFHP of Nutrition and Metabolism important?
Deficiencies may explain other problems fluid intake is important problems r/t being underweight or obese skin is 1st line of defense against infection treatment may interfere with metabolism
What do nutrients do?
supply the body with necessary elements for growth
List the different kinds of nutrients

Micronutrients (list)
vitamins and minerals
Vitamins
Water soluble: peed out by body if excess
Fat soluble: can be toxic if in excess because body holds onto these.
List the fat soluble vitamins
ADEK
Metabolism
process of producing and using energy within body cells fueled by nutrients -energy produced -energy used -needs to be balanced for health THYROID HORMONES PLAY A MAJOR ROLE
Ways energy is used in the body
to maintain essential life processes: breathing, circulation, nervous system function
to support non essential life activities: running, working, thinking, stress management, digestion/absorption.
Basal Metabolic Rate (BMR)
the amount of energy required for essential life processes.
breathing circulation and nervous system
when is BMR measured?
when the body is physically, metabolically, and emotionally at rest.
influenced by: activity, hormonal imbalance, temperature, stress, and illness.
anabolism
Cell building.
excess stored as fat and can be used for body needs if nutritional intake is not sufficient
fat excess=weight gain
