Background/aims: The incidence of hepatocellular carcinoma (HCC) in Mongolia is growing at an alarming rate. Traditional dried food was suggested as the major reason for high HCC numbers, due to possible aflatoxin contamination during manufacturing. We thus aimed to measure aflatoxin concentrations in Mongolian food samples.
Methods: Samples of traditional Mongolian food ('aaruul', dried meat, and dried noodles; in total 11 samples) were collected and shipped to Germany. The food samples were analyzed for aflatoxins by extraction, immunoaffinity purification, and subsequent HPLC with fluorescence detection.
Results: The traditional Mongolian food samples did not contain any detectable amounts of aflatoxin.
Conclusion: Since Mongolian food does not contain aflatoxins, the cause for the increasing HCC incidence in Mongolia is probably due to a high prevalence of viral hepatitides. Further studies to identify the reason for this development are warranted.

Background: Mongolian cattle, a unique breed indigenous to China, represent valuable genetic resources and serve as important sources of meat and milk. However, there is a lack of high-quality genomes in cattle, which limits biological research and breeding improvement.
Findings: In this study, we conducted whole-genome sequencing on a Mongolian bull.
High Meat Intake and Ferritin Levels in Relation to Cardiovascular Risk Among Individuals with Diabetes in Mongolia.

Background/objectives: Mongolian diets are characterized by high meat consumption, which may contribute to dietary iron intake and influence ferritin levels and cardiovascular risk. Elevated ferritin levels have been associated with inflammation and cardiovascular disease (CVD) risk in various populations; however, the specific effects of high meat intake and ferritin levels on CVD risk in Mongolian individuals with diabetes remain unclear. This study aimed to assess the relationship between meat intake, ferritin levels, and cardiovascular risk markers in a diabetic Mongolian population.

We aimed to estimate the prevalence of vitamin D deficiency in Mongolian men aged from 15 to 49 years at the National level as part of the Fifth National Nutrition Survey in 2016. This was a cross-sectional survey, conducted between September and November in 21 aimags of 4 economic regions of the country, and also in Ulaanbaatar. Given the regional differences in lifestyle and nutritional status, the target populations were stratified into 5 strata based on their economic region and in Ulaanbaatar, with equal samples drawn from each stratum using a cluster-randomized sampling design.

Inner Mongolian cheese is easily spoiled during storage due to hydrolysis and microbial contamination. Herein, the guar gum (GG)/chitosan (CS) edible films reinforced with orange essential oil nanoemulsion (OEON) were fabricated for cheese preservation. Results showed 4 % OEON with the optimal droplet size (380 ± 44.

Objective: To quantify and compare concurrent within-person trends in lifestyle risks, nutrition status, and drivers of food choice among urban migrants in Central Asia.
Design: We collected panel data on household structure, drivers of food choice, nutrition knowledge, and diverse measures of nutrition status and lifestyle risk from urban migrants at 0, 3, 6, and 9 months using harmonized methodology in two cities. Trends were analyzed using mixed-effects models and qualitatively compared within and between cities.
