Today, nutritionists from the United States presented the results of their new scientific study on how the intestinal microbiome of a person and entire tribes changes and how this can be converted for the benefit of science. As the main subjects of research specialists were people from four different tribes in the diet of Nepal – we are talking about the tribes of Taru, Raji, Raut and Chepang. Despite the fact that all these tribes have almost identical cultural characteristics and history, they differ in their way of life and, as a consequence, their diet – and based on these differences and similarities, specialists have studied in detail how different types of diets and lifestyle affect microbiome .
Having collected samples of several people belonging to different tribes, they found that the lifestyle and type of diet most directly determines the level of certain intestinal bacteria in a person’s microbiome. So, as a basis for comparison, they took the Tara tribe – which is the most settled and developed in relation to agriculture – and compared its diet with diets of much more nomadic representatives of the Chepang and Raji tribes.
Despite the fact that these last two tribes have also recently begun to change their way of life and diet towards sedentary, nevertheless, scientists have registered a noticeable difference in the development of their microbiome. So, in nomadic tribes, noticeably higher rates of bacteria of triponema and ruminobacteria were found, in contrast to settled tribes – however, they also differed between the inhabitants of the same tribe in terms of age difference. Thus, experts were able to prove one important hypothesis – the hypothesis that the intestinal microbiome can dramatically change during the life of one generation.
More precisely, during the life of one person. This discovery in itself entails potentially many changes in modern therapies for the treatment of intestinal microbiome. In addition, this will allow specialists to delve deeper into the processes of redistribution of intestinal microbes and their evolution over a certain amount of time. It remains only to wait for the end of research.
