vitamin, mineral and fluid requirements Flashcards
vitamin function is to
release energy from ingested food and serve various roles to maintain homeostasis
13 essential vitamins are classified as
water-soluble or fat-soluble
water-soluble vitamins
not stored in the body as they are lost in urine
help regulate metabolism, tissue synthesis, cell membrane function
fat-soluble vitamins
stored in body fat and the liver; help enhance tissue formation, prevent cell damage, and form compounds
some vitamins serve as antioxidants which
help to thwart tissue damage caused by free radicals
