Abstract
Yakutia is an endemic territory for iodine content in the environment. The region of Central Yakutia belongs to the biogeochemical areas known for iodine deficiency. Goiter etiology is associated with low levels of iodine in food. Thus, we analyzed the iodine content in local raw materials (plants, animals, and natural water) in the biogeochemical areas of Central Yakutia. The obtained results show a low amount of iodine in various water sources (river water, lake water, snow water, and rainwater), even in other areas of Yakutia. The iodine content analysis was carried out in food of local origin (beef, horse meat, milk, potatoes, beets, and carrots) as essential food products. Compared to table values, the lowest iodine level was found in milk (3.3 times lower than the standard rate), vegetables (1.7 times lower), and fish (2 times lower). Satisfying values were registered only in meat. The approximate daily iodine intake of a resident has averaged 65.3 mcg, while the standard input is 130–150 mcg/day.
