Relation Between Gut Microbiota Composition and Traditional Spontaneous Fermented Dairy Foods Among Kazakh Nomads in Xinjiang, China

Abstract

The human gastrointestinal tract represents one of the most densely populated microbial ecosystems studied to date. Although this microbial consortium has been recognized to have a crucial impact on human health, its precise composition is still subject to intense investigation, as people from different regions have different gut microbiota structures. The Kazakh nomads in Xinjiang, China still retain their nomadic lifestyle and traditional diet. Their specific diet style and ancient genetic background shaped their gut microbiota to contain unique characteristics. In present study, the compositions of the gut microbiota and fermented dairy foods were assessed by high-throughput sequencing of the 16S rRNA gene. Twenty-nine Kazakh nomads were recruited, and 33 traditional fermented dairy foods were collected from five pasturing areas (Buerjin, Zhaosu, Nilka, Tekes, and Fuhai) in northern Xinjiang, China. The correlation of the physical index with the gut microbiota was also analyzed. The unique diet style of Kazakh may be a critical factor in keeping their gut microbiota in a balanced state and help them to remain in good health.

Colonization Ability and Impact on Human Gut Microbiota of Foodborne Microbes From Traditional or Probiotic-Added Fermented Foods: A Systematic Review

“…The majority of fermented foods were represented by dairy products (88)(89)(90), especially fermented milk (91)(92)(93), yogurt (94)(95)(96), and different cheese varieties (97). Other fermented foods included plant and vegetable based (15,98), fermented rice (99), and diverse home-made (100) and local (101)(102)(103) fermented products. The amount of ingested fermented foods varied between 135 and 400 g/day, although not all articles reported this information, and when reported, the information was based on food frequency questionnaire (FFQ).…”

Two Faces of Fermented Foods—The Benefits and Threats of Its Consumption

“…Due to the production of chemokines, cytokines, growth factors, or immunoglobulins, MALT acts as a microbial fighter. Furthermore, probiotics influence the balance of the gut microbiome composition, reducing the risk of disease gut ( Tokarz-Deptuła and Deptuła, 2017 ; Azad et al, 2018 ; Li et al, 2019 ; Uusitupa et al, 2020 ; Zhang et al, 2021 ). As microbes are able to produce neurochemicals, as well as respond to them, they can play a crucial role in the treatment of depressive and anxiety disorders ( Romijn et al, 2017 ).…”

Association between the metabolic score for insulin resistance and prostate cancer: a cross-sectional study in Xinjiang

“…(3) Xinjiang is located in northwestern of China, at the crossroads of Central and West Asia, and is a region of multi-ethnic coexistence, which avoids the bias that studying a particular ethnic group bring to the results. In the Xinjiang region, various ethnic groups develop different dietary habits as and lifestyle ( Li et al, 2019 ), distinct from the inland provinces of China. Studies have found that special dietary patterns and lifestyles in the Xinjiang region influence the prevalence of metabolic syndrome and its components ( Zhang et al, 2024 ; Hailili et al, 2021 ; Wang et al, 2021 ).…”
