Iodine deficiency in UK schoolgirls/Authors' reply

[...] we urge caution over the conclusion that iodine intake is inversely related to egg consumption, particularly when other studies with more rigorous dietary methods have shown the converse.5 Eggs are an excellent source of several important nutrients, and an inverse association between egg consumption and iodine status should not be promulgated on the basis of a flawed food frequency questionnaire. [...] in developed countries such as the UK there is a strong public-health objective to lower salt intake to reduce the risk of hypertension. [...] only 10% of UK salt intake is estimated to be added to food at the table, so dialogue with the food and salt industries to establish the feasibility of adding iodised salt to processed food is essential.
