PIES and CAT LITTER even though
her parents provide her with a varied
and healthy diet. Her parents can’t
solve this mystery. CAN YOU??
Minerals
•Found
in nearly all foods
•Do NOT supply energy
•Regulate body chemistry and
body functions.
•Can not be produced by our
body. Must be EATEN.

BIO-AVAILABILITY




Our bodies vary in their capabilities to
absorb & use of available minerals
Minerals may be present in foods but, they
are NOT Bioavailable unless our body can
absorb them
Minerals from animal products are absorbed
better
Mineral content of plant products depends
on soil
