In several Russian regions, including Kamchatka, Lipetsk, Vologda, and Orenburg, people face a higher risk of selenium deficiency because the soil in these areas contains very low levels of this essential trace element. Selenium plays a crucial role in supporting immune function, maintaining metabolic balance, and protecting cells from oxidative stress. Recent research from Sechenov Moscow State Medical University indicates a link between selenium deficiency and the development of obesity and metabolic syndrome. This finding was shared with socialbites.ca by the university’s press service.
When selenium is lacking, the immune system may weaken, cognitive performance can decline, and adaptation to environmental changes can be impaired. There is also concern about an increased risk of cancers and cardiovascular diseases, along with potential disruptions to reproductive health. These observations were highlighted by Anatoly Skalny, a Doctor of Medical Sciences and director of the Center for Bioelementology and Human Ecology at Sechenov University, during a briefing with socialbites.ca. The center has also identified connections between selenium deficiency and obesity-related metabolic issues.
Among the Russian regions, Kamchatka, Lipetsk, Vologda, and Orenburg are cited as having notably low soil selenium content, while regions such as Kabardino-Balkaria, Dagestan, Mordovia, the Chechen Republic, and Tambov are recognized for comparatively higher selenium availability. In areas with low selenium, iodine deficiency often accompanies it, likely because the lack of selenium can hinder iodine absorption. This pattern has been observed in residents of the Orenburg region, according to Skalny’s remarks to socialbites.ca.
The scientist noted that in Central Europe and many other areas where soil selenium is scarce, programs exist to fortify foods with selenium. At the Center for Bioelementology and Human Ecology, similar initiatives are being pursued in Russia to improve public health by enriching foods and drinking water, guiding dietary adjustments, and strengthening local food and agricultural systems with targeted interventions. These efforts aim to support healthier living in specific regions and to foster regional nutrition resilience through science-based policies and practicable programs.
Beyond population-level strategies, researchers are exploring how amino acid management and nutritional planning may influence age-related metabolic changes. By understanding how trace elements interact with dietary components, scientists hope to develop clearer guidance on preventing obesity and supporting metabolic health across diverse populations.
