More on Iodised Salt S K SHARMA (June 1) has raised fresh issues on iodised salt: (a) there is a large population that is now suffering from excess iodine and (b) food inspectors are forbidden to collect so-called iodised salt samples from the market for checking and assessing iodine content. The WHO is a scientific body, is not an activist set-up and its findings are based on global research. Hence, one has to give credence to its findings till they are disproved by further research and fresh scientific evidence. The present WHO findings are: through adaptive mechanisms normal people exposed to excess iodine remain euthyroid and free of goiter. In Japan where dietary iodine intakes are high it has been shown that normal people who are not iodine deficient can maintain normal thyroid function states even at several milligrams of dietary iodine intake, that the incidence of non-toxic diffuse goiter and toxic nodular goiter is markedly decreased by high dietary iodine intake, that the incidence of Graves' disease and Hashimoto disease does not appear to be affected by high intakes of dietary iodine. Current estimates of daily iodine intakes in Canada and the US are substantially above physiological need in the range of 460
