P. Hendrix et al., DAILY DIETARY RUBIDIUM INTAKE IN BELGIUM USING DUPLICATE PORTION SAMPLING, ZEITSCHRIFT FUR LEBENSMITTEL-UNTERSUCHUNG UND-FORSCHUNG A-FOOD RESEARCH AND TECHNOLOGY, 204(3), 1997, pp. 165-167
Daily dietary rubidium intake in Belgium was evaluated by duplicate po
rtion sampling. Sample destruction in a microwave oven and atomic abso
rption spectrometric analysis were used to measure this element. The m
ean intake of 2.2 +/- 0.3 mg/day is similar to levels found for most o
ther countries. Since the necessity of this element for humans remains
unproven, the intake level could not be compared to a recommended ran
ge for a safe and adequate dietary intake.
