The purpose of the study is to determine the uptake of calcium from fish bone meal from salmon and cod in 12 healthy volunteers. A test meal labelled with trace amounts of a radioactive calcium isotope (Ca47) will be given after an overnight fast and whole body retention of calcium will be measured on day 13, 21, and 24 after the test meal day.
