Lifestyle Shapes Oral Microbiomes Over Time

This study explores how varying lifestyles in Nepali populations—ranging from foraging to industrialization—affect oral microbiomes. Researchers found that microbial diversity remained constant, but specific microbial compositions changed with lifestyle transitions. Factors like diet and smoking significantly influenced these shifts. Key microbes such as Streptobacillus varied based on lifestyle. These findings provide insights into how oral microbiomes are shaped by habits, offering potential strategies for promoting oral and systemic health. Understanding these dynamics can help tailor health recommendations to different populations.
