Researchers have taken a closer look at the typical microorganisms found in the digestive systems of healthy individuals from Pakistan. Their interest stems from Pakistan's diverse population in terms of diet, genetics, and environmental factors. Given that Pakistan is one of the world's most populated countries and classified as a Lower Middle Income Country, the gut microbiome of its residents proves to be a subject of considerable significance. The study encompassed the analysis of gut microbes of healthy individuals of normal weight by examining the genetic material associated with these microorganisms, known as 16S rRNA. Participants from different areas in Pakistan completed questionnaires, providing insights into their lifestyles and diets. Scientists then linked this information to the participants' health status using statistical methods that investigated patterns relating to diet and health. The analysis showed that where a person lives within Pakistan is a major factor that differentiates their gut microbes. For example, the study demonstrated that men's gut microbes appear to be more finely tuned to their local environments compared to women. The research also revealed that people's ethnicity, diet, and lifestyle all contribute to variations in the kinds of microorganisms present in their gut. Some specific microorganisms were found more often in people who consumed certain foods like pickles, fresh fruits, rice, and cheese. Furthermore, the team saw links between microorganisms and aspects such as diet, sleep habits, work status, and health history. In identifying the shared characteristics of the Pakistani gut microbiota, researchers employed a method that accounted for the presence and consistency of various microbial species, even considering factors like gender and provincial residence. They also utilized a neutral model to uncover the central microbiome shaped by the environment. The findings offer a detailed view into the gut microbiome typical of healthy Pakistani individuals in urban areas, focusing on the most populous provinces and ethnic groups. Such insights provide a reference for investigating how these microbiomes vary with disease and can also aid in developing personalized diet and lifestyle changes to encourage healthy digestion, especially in the context of Lower Middle Income Countries like Pakistan.
