UPDATE ON THE DAILY IODINE INTAKE IN JAPAN: Since writing part VIII of this series, a document has been brought to my attention that I feel has tremendous significance in relation to a major controversy being discussed in this series. It is a recently published letter to the editor entitled "The average of dietary iodine intake due to the ingestion of seaweeds is 1.2 mg/day in Japan" by Nagataki1. As the title suggests, it supports my conclusion published in part V of this series, based on a review of the literature available to me at that time, that Abraham's claim concerning the Japanese average daily intake of dietary iodine, primarily from seaweed ingestion, is incorrect. As you may recall, Abraham has claimed that the average intake of iodine in Japan is approximately 13.8 mg per day, mainly from seaweed. In contrast, my review of the literature suggested that the average Japanese intake ranges from 1-5 mg per day. However, Nagataki1 in his recently published paper suggests that the average intake may even be less than this.
