Diet / food:
- More plant variety and fiber can increase microbial diversity.
- Highly processed foods and low fiber may reduce it.
Gut microbiome:
- Antibiotics can temporarily lower diversity.
- Ongoing gut imbalances can make diversity harder to rebuild.
Lifestyle (sleep, stress):
- Poor sleep and chronic stress can shift microbial activity.
- Regular physical activity may support a healthier gut ecosystem.
Biological factors:
- Age, hormones, and genetics can influence which microbes thrive.
- Illnesses and travel can change gut conditions quickly.
