Iodine deficiency still exists in many countries worldwide, to a certain degree this is also true for Germany. Food of animal origin can be a good source for iodine depending on the feed. To investigate the possible use of laying hen feed enriched with iodine, we conducted a feeding experiment with 40 laying hens receiving feed with different amounts of iodine either as KIO3 or in the form of seaweed. Iodine concentration in eggs increased significantly depending on iodine intake after a 2 week period. Seaweed could also be used as an iodine source by the hens. A subsequent consumption study with 24 volunteers showed that eggs enriched with iodine can increase human's iodine excretion and therefore improve human's iodine supply. This new strategy is thought to accompany salt iodization programs, not to replace them.
全球许多国家仍存在碘缺乏问题，德国在一定程度上也是如此。取决于饲料，动物源性食品可能是碘的良好来源。为了研究富含碘的蛋鸡饲料的可能用途，我们用40只蛋鸡进行了一项饲养实验，这些蛋鸡分别食用添加不同量碘（以碘酸钾形式或海藻形式）的饲料。两周后，鸡蛋中的碘浓度随碘摄入量的增加而显著升高。海藻也可以被母鸡用作碘源。随后对24名志愿者进行的消费研究表明，富含碘的鸡蛋可以增加人体的碘排泄，从而改善人体的碘供应。人们认为这种新策略应与食盐加碘计划相辅相成，而非取而代之。
