Abstract
The article deals with longevity of people living in a low-populated northern region. There has been a shift in gender and territorial indicators due to active migration of the elderly from the country to urban settlements. The authors review average life expectancy of people who have reached retirement age, pointing out increased probability of reaching an advanced age with persisting gender differences. The authors argue that one of factors contributing to longevity of the Yakut people is consumption of traditional meat products from horse meat (flesh of colt). It was pointed out that the source of unique meat composition of the Yakut horse, affecting longevity, is the feed frozen by natural cold (cryo-feed) with a high content of essential fatty acids. Conducted field studies demonstrated that the content of linoleic acid increased by 2.1 times, and α-linolenic acid by 1.8 times in the cryo-feed compared with their respective summer levels. The economic background of green cryo-feed use is presented as a basis for increasing the nutritional value of the Yakut horse meat.
