説明

The traditional diet of Mongolian nomads consists of dairy products and meat, and they have been able to satisfy their nutritional needs without consumption of vegetables. In the winters of 2000 and 2001, large numbers of Mongolian livestock died from extreme cold. As a result, there were notable changes in the diet of the Mongolian nomads compared with that before the two successive harsh winters. Although there was no marked difference in mean total energy ingestion by males between 1997 (2, 191±589kcal) and 2002 (2, 108±618kcal), the quantity and frequency of dairy and meat products ingested decreased and those of flour products ingested increased. The amount of flour consumption increased 3-fold from that in 1997. Adult males are dependent on kumiss, which accounts for 50% of their total energy intake and all of their vitamin C requirement. However, kumiss was not available in 2002. As a result of the decreased ingestion of dairy products, various active ingredients contained in such foods could not be taken in, and this may have had a negative impact on the health of Mongolian nomads, whose eating habits now stand at a crossroads under the influence of modernization.
