Impact of the Food Matrix on Iodine Bioavailability

This study is a randomized crossover trial, lasting 12 days in total, which will assess the difference in iodine bioavailability (as a percentage of iodine consumed that is excreted in urine) from three iodine-rich foods; semi-skimmed milk, white fish, and dried seaweed sheets. Each of the three foods will provide approximately 140µg of iodine, and iodine excretion will be monitored for 36 hours following food ingestion via collection and analysis of urine.
