Principales fuentes dietéticas de yodo en población adulta española.

Abstract

Background: Iodine is an essential element for a proper human body performance, due to this; its intake must be enough to guarantee this performance. There are some groups of aliments, such as seaweeds, milky products and iodize salt, in which the iodine content is higher. Methods: Along the research study, 418 people from different Spanish locations were studied; this is a representative sample of the Spanish population. In order to make a dietary assessment, surveys about feeding habits and 24 hours dietary recall of 2 days have been collected. These data were used to define the iodine contribution from all the aliments within the analyzed diets, in order to obtain the main iodine sources. Results: The main iodine dietary sources, in the population under study, aside the iodized salt, are milk, seafood and fish. Other iodine sources, with a low contribution level, were alcoholic drinks in male subjects and seaweeds in female subjects. Conclusions: Taking into account the outcomes from the research study, we infer that, with the exception of iodized salt, the aliments that contribute the most in the Spanish population diet are milky products, fish and seafood.
