Vegans iodine sources

As the major sources of iodine in the diet are animal based, it is reasonable to suggest that vegans (a strict vegetarian diet of plant foods only) (Table 45.1) are likely to have a low dietary intake of iodine. So where can vegans obtain their dietary iodine ... 

Possible dietary sources of iodine for vegans include iodized salt and seaweed (Lightowler and Davies, 1996). In many developing countries, iodized salt is considered a good medium for iodine prophylaxis. However, although some iodized salt contains 1527-25 57 fig/lOOg (equivalent to 76-128 pg/teaspoon), encouragement to use this... 

Dietary Supplements As dietary supplements are an important source of iodine in the vegan diet, the accurate assessment of iodine intake from this source is important. The use of dietary supplements by vegans is a crucial factor in determining their iodine intake and assessing whether supplement users could be at risk of excessive intakes of iodine. However, dietary supplements may be a confounding factor in the assessment of iodine intake, as there is uncertainty and variability in their iodine content (Lee et at, 1994). Furthermore, an excessive intake of iodine through some dietary supplements is not difficult because of their concentrated formulation and manufacmrers recommendations about the number of tablets to be taken, which may further exacerbate excessive intake.
