Adiposity, Iron-deficiency
Conditions
Brief summary
Adiposity is a state of sub-clinical inflammation, thus hepcidin is increased in adiposity, often leading to iron deficiency in this population group. Central adiposity is generally considered having a greater negative effect on health compared to peripheral adiposity. Whether this can be also seen in hepcidin and thereby in iron absorption is uncertain.
Interventions
Participants have to consume a test meal containing stable iron isotopes in order to determine iron absorption
