Diet directly influence the composition of gut microbiomes. A diet rich in fibre (fruit. & vegetables) and fermented food tends to support diverse microbiome.
Exercise, sleep, and stress level can influence the composition and health of microbiome.
Antibiotics may damage benefical gut microbes while treating harmful bacterial infection. This may disrupt the gut microbiome and leads to dysbiosis.
Dysbiosis is the imbalance in the gut microbiome, where harmful bacteria may outnumber beneficial ones. This causes gastrointestinal disorders, metabolic disorders, or mental health (mood) condition.
Birth and early life affect gut miccrobiome (e.g. mode of delivery (how a baby is born) & breastfeeding). Early life experiences and exposure also shape the microbiome.
